Nexus 5X stays awake after charging
Nexus 5X running 6.0.1 shows awake after disconnecting charger cable.
Reboot helps but later the awake state persists if I connect charger back.

I think its a issue with the dose system

Thx! Any ideas on how to fix? Later I could try complete reset but it would be better to know the root cause.

Turn off doze and try

As far as I remember there is no such control in Settings. If you mean "Battery saver" - it is OFF by default.

Factory data reset helped but didn't help to know the root-cause.

I've found the root cause for awake state - it is Viber.
To detect this I've completely removed all third party software and left only one came from Google (my Nexus 5X comes only with Google and no bloatware).
So adding apps one by one I was checking the issue appearance after every.
The issue back after adding Viber and immediately has gone after removing it.

Packages for API level

Hi, I'm new to Android development studio. My question is, if I am not using Android Emulator then do I need to install only these checked packages for every API level ?

Yes, that is the actual SDK, which is the source code, so definitely install it if you are targetting that API level. About Google API, depends on the use case. If you are going to talk to the internet or use Play Services you will need them for sure

Ok. It means Android SDK platform and sources for Android SDK of API levels which I want to use. What about Google API? Do I need to install that also ?

Economist app stuck with old issues
This has happened to me repeatedly with the Economist app on Android. Basically the app usually automatically downloads the weekly issue by push notification, but sometimes it simply doesn't do that. When I uninstall the app and reinstall it.. it's stuck at the December 19th issue of 2015.
I figured this may be a date problem, so I set the time manually on my phone.. no luck.
Any ideas? And if someone is to suggest this isn't the right stack exchange site for such questions please tell me which one I should use instead .

Contact the app maintainer?

Already did that many many many times.. they keep on sending updates that sometimes fix it and sometimes it doesn't..

I basically connected my android device to the internet using a VPN service (unotelly.. I currently live in Lebanon although when I first registered with the economist.. I was living in Canada).
Connecting via the vpn solved the problem

Photos and videos visible on phone., but impossible to import to a Mac
I have a Moto G 2nd gen, with android 6 (marshmallow).
It appears that the phone contains some photos and videos which I can see through the Gallery, but I am unable to import to Photos.app on OSX.
The camera app is setup to store images on SD.
I have tried connecting the phone as a camera (PTP) and nothing shows up.
I have also tried connecting the phone as a media device (MTP) and use the android transfer app, but the pictures do not show up in DCIM/ under "internal storage", and the "sd card" file list doesn't contain a DCIM/ directory at all.
I have tried wiping the cache partition, ejecting and re-adding the sd card but nothing worked, I cannot find these files.
Where are they, and how do I get them out of the phone?

try using apps like shareit which is available both for Mac and Android

Would solutions involving ADB be acceptable? Or solutions involving 3rd party apps via WiFi?

I would say yes, but only if they come with an explanation of why it's not possible with standard stuff,

If the physical transfer does not work, you could try an app like WiFi File Transfer
It uses your WiFi to transfer files, so that might be worth a try.

so, file is still invisible in the android transfer app and some others (e.g. airmore doesn't see the folder) but for some reason wififiletransfer shows all the proper directories. Since nobody offered another solution, I'm going to award the bounty to this one.

It appears that the phone contains some photos and videos which I can see through the Gallery, but I am unable to import to Photos.app on OSX.

From what I understand, you seem to be able to view the photos in your gallery but you're unable to find them when you connect the phone to your Mac. And you seem to be searching them only in DCIM. Are you sure that these photos exist in locations other that DCIM perhaps?
If you're able to view these photos and videos in your phone's gallery, it means that they exist somewhere on your device. You could start with figuring out as to where they are. In the gallery, if you tap on info, it should show you the file name and where it's located. Once you chance upon the right location, try navigating to that specific location, maybe via a file explorer. This is to be certain that other generic apps also are able to find these pictures
An immediate solution I could find is:

Select those images from the gallery
Hit the share button
Use the Google Photos app and have it uploaded on to your google photos.
Head to photos.google.com on your Mac and download those photos from there.

Note - It doesn't really have to be photos app. You could use just about anything to have it transferred out. Even old-school bluetooth.

Attempt to root AVD running Android 4.4/5.1 is failing
I have referred to various posts but I don't think they seem to work, at all, whatsoever, when it comes to AVDs with Android 4.4 or 5.1.
I felt a need to post this.
So before posting this question, I have understood a basic need for rooting AVDs or even any device.

Mount /system in rw mode.
Push su binary; optionally busybox binary.
do chmod to them, say, 6755. That should be it.

I followed posts and successfully rooted AVD with Android 2.2, however, I tried to repeat the same thing for Android 4.4 or 5.1 (both with SELinux disabled), but it seems that there is some kind of fallback mechanism.
For Android 4.4 and 5.1, /system will be mounted in rw mode, but, as soon as I try to push binaries, it gets reverted back to ro mode. Furthermore, it won't get back to rw mode as well, at least until I do a reboot. I keep getting a permission denied error.
Since these worked for Android 2.2 (with a modification in filesystem type and mountpoint), I intend to execute following commands (for Android 4.4 and 5.1):
adb root
adb shell /system/bin/mount -o rw,remount -t ext4 /dev/block/vda /system
adb push su /system/xbin/su
adb shell chmod 06755 /system
adb shell chmod 06755 /system/xbin/su

Anyone who has managed to root AVDs running these versions of Android are requested to help me in this.
I have experience with Android Studio & Windows.

I have tested and found that irrespective of the version of Android, if the ABI is arm, armeabi or maybe even mips (not sure), the process of rooting is going to work. They didn't worked for me, as of now, if the ABI is x86 or x86_x64 for Android 4 and 4+.
Below, anything after "#" is supposed to be a helpful comment.
Testing working on - Android 1.x, 2.x, 3.x, 4.0, 4.1, 4.2 (add additional space in subsequent boot):
adb shell mount
# Preferred command: adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock0 /system
adb shell mount -o rw,remount /system
adb push su /system/xbin/su
# Appropriate su binary from Chainfire's SuperSu.zip package.
adb shell chmod 06755 /system
adb shell chmod 06755 /system/xbin/su
adb install "Super user.apk"
# Update the su binary for sure.
#adb install "Rootchecker app OR Terminal Emulator app to test."

Testing working on - Android 4.3-4.4 (add additional space in subsequent boot), 5.1, 6.0:
adb shell df
# See the available space in /system
adb shell mount -o remount,rw /system
adb push su /system/bin/su
adb shell chmod 0755 /system/bin/su
adb push su /system/xbin/su
adb shell chmod 0755 /system/xbin/su
adb shell su --install
adb shell "su --daemon&"
adb shell setenforce 0
# optional and recommended; adb shell mount -o remount,ro /system
adb install "Super user app"
# Update the su binary.
#adb install "Rootchecker app OR Terminal Emulator app to test."

You know that x86 and ARM require different binaries, right? There's no way a binary compiled for ARM would work on android-x86.

Can't view Location (textual desciption) information in Windows when opening picture taken with Camera app
On my Samsung Galaxy SIII, I have enabled GPS on my device and have also enabled the GPS tag feature in my Camera application. When a picture is taken, GPS information is attached to the image, and then as soon as either a mobile data connection or Wi-Fi connection is available, somehow the Gallery application is able to retrieve textual information about the street name, city, and country, corresponding to the GPS location stored with the image. When I press the menu hardware key and then select Details I can view this information alongside other information associated with the picture taken.

However, when I attach the phone to my Windows 7 PC and open a picture directly as Computer -> GT-I9300 -> Phone -DCIM -> Camera -> date_sequentialnumber.jpg I am not able to view the embedded textual/alphabetic location information which I was able to see when I was viewing the picture in the Gallery application.

So, what I would like to ask is:

Is it possible to embed the textual location information in the image (besides just GPS coordinates) as EXIF information inside the JPEG so that this information can also be viewed on the PC even when the PC has no network access?
If this information is already embedded but not being displayed by the Windows Live, then are there better, free, image (and video) viewing programs for Windows 7 which will allow you to view this information?

EDIT:
According to this Wikipedia article, the process of enriching geographical coordinates with a description of a location is known as reverse geocoding. This is what the Gallery application above was doing. Also according to this other Wikipedia article Geotagging can also attach not only coordinates, but also place names, which is what I'm after. The EXIF standard does not seem to include any specific tags for place names, although camera manufacturers can embed their own custom format metadata using the MakerNote tag. Upon searching for images with the Advanced Google Image Search, downloading, and viewing with Gimp 2.8.4 I found place name information embedded in the ImageDescription EXIF tag, whereas images downloaded from Panoramio it seems do not contain EXIF informaiton.
So, my question is, how do I embed reverse geocoded place name information inside the ImageDescription EXIF tag of pictures from within my Android smartphone? Thanks!

I guess XNViewMP can show MakerNote tags. You can grab the portable version and give it a try.

Thank you for your comment. I've tried installin XNViewMP on my PC. It's a nice software indeed. However the Makernotes tag under EXIF is empty, and the reverse geocoded information (place name) does not appear anywhere in the Info panel (EXIF data etc...). Hence, I can conclude that the Android Gallery application retrieves the reverse geocoded information from the Internet and displays it but does not embed the information inside the displayed pictures. Regards. Thanks.

Block some sources from Google Now?
I'm seeing some cards from the Daily Mail when I look at Google Now. How can I prevent Google Now surfacing cards from sources that I dislike?

Tap the menu button at the top right of the offending card, there should be an option for "Never show stories from the Daily Mail".

Has Android 6 Update Caused PC Connection Issues for Galaxy Note 4?
Since updating my Samsung Galaxy Note 4 to version 6 of the Marshmallow operating system, it won't show up when I connect it to my PC.  Any recommendations? Is anyone else having a problem?  It may NOT be related to the Android update -- but I've never had this issue before.  Thanks for any help.

Have you changed the USB settings on the phone from just charging to mtp?
Pull down the notification bar while it is plugged in and select the USB notification followed by Mtp which is just file transfer.
Some info on that:
http://m.androidcentral.com/inside-marshmallow-usb-connection-options

Thank you so much!  That got it!  The key wasn't going to Settings / Notifications -- it was actually swiping down on the Notifications screen.  I am so grateful for your response.

Glad to help! If the answer was accurate, would you mind just marking it as correct so the thread doesn't stay open. Thanks!

You bet!  I will be happy to mark your answer as correct, just tell me how.  I'm new to this forum, but there was nothing in the Q&A search instructing me on how to do it!  Not seeing any "mark answer as correct," etc.

@KipKirby underneath the up and down arrows on the answer there should be a check. Just hit that. Thanks!

Boy, they don't make THAT very clear, do they?!  :-)  Anyway, I followed your instructions and the check mark turned green, so I take that as a positive sign!  LOL.  Thanks again.  I'm sure this won't be my last question here in the forum, but you were the only one to answer, and you solved my problem perfectly.  Thanks so much!

Whether a new user of my old number can see my old WhatsApp messages?
I was using WhatsApp with my mobile number since last 1 year. Suddenly the number got deactivated due to no call/messages for long days. However, I got to know that the same number has been allotted to another person-B.
Now I am wondering whether the person-B can be seeing my old WhatsApp messages those I had 1 year before attached to the same number?

They cannot see your messages because they would not be able to sign into your account. Without your password and/or physical access to your phone where your messages are saved there is no way they will be able to access your messages.
An entirely new account can be created for the new owner of that number, but it is separate from your old account and does not have access to your old messages.

There is an important note: If people don't realize that you have a new number, the new account / old number might get messages which were written for you. It happened to me. I could still see the old messages that my friend has received and the new messages that the stranger received - in the same chat.

I had asked something along the same lines (although not identical) just a few days ago. Question
Whatsapp stores messages locally in your phone's internal storage under Whatsapp/databases/ <<*.crypt12>>
Apart from this, the latest message backup will be stored in your google drive. (This is only if you have enabled the option to store a backup on your google drive)
So in essence, there is no way the person with your old number can gain access to your previous chat history.
What could happen is your current contacts, who might have your old number, would see that person in their whatsapp contacts.

Why are my call settings disabled (and which settings require operator support and which settings are normally included in service plans)?
As shown in the screenshot below, on my Samsung Galaxy SIII, when I go to Phone -> Call Settings, almost everything is disabled/grayed out. I have a SIM card inside my phone but have not topped up my mobile phone subscription this month. I wonder whether that is the reason why these features are disabled, or whether the reason is that my network provider doesn't support them (after all I am still able to receive incoming calls and SMSs). Is this the case?
I would like to use features such as:

placing a call on hold, retrieving a held call, and dialling second (or other) calls
make multipary/conference calls by merging calls
set call diverting (including diverting calls to the voicemail server)
set call barring
set call waiting
set call forwarding
set fixed dialling numbers (FDNs)

I wonder which of these features require support for these features from the network operator. I also would like to know whether, and if not then which of these, features are nowadays provided free of charge with a subscription plan from the network operator, and which features normally would not be included and cost extra. Receiving phone calls and SMS messages does not require the account associated with the SIM card to be topped-up (hence is totally free of charge). I know this could vary from network operator to network operator, but due to network operator competitiveness, I would expect most network operator to provide more or less the same features for free as others, and charge for features in case the other operators also do.
Thanks.

EDIT:
I've topped up my phone with my pay-as-you-go plan and as a result all of the entries in the above screenshot have become enabled.

EDIT:
Just for the record, I've contacted my network operator. The monthly 10€ pay-as-you-go plan I'm subscribed to happens to include 400 phone hours within the same country, 400 SMS to phone numbers within the same country, 1GB fast Internet followed by unlimited slow Internet. However calls abroad as well as calls to the provider's answering machine service are charged separately/extra. Also, while Caller ID and Call Forwarding/Diverting services are free of charge, Call Waiting will soon incur charges with my provider. I guess other service providers would offer similar service and features at roughly the same price. Regards.

I'd first ask the network operator. Most of what you've listed are "service features" the operator needs to explicitly support – so it might well be that's why they're disabled in call settings (they might be detected as "being absent").

Thank you for your answer. Besides my particular network operator, I was also interested in knowing which of these services are included on average by most network operators with the most common basic pay-as-you go plans and which ones among the services I listed tend to cost extra nowadays. Thanks.

That's no question fitting this site (off-topic for being "Android independent"). We don't cover "all about cell phones" here ;)

Sorry, I thought those features would have had to have support from the Android OS to function properly, plus the screenshot I posted is Android specific. Plus, I couldn't find a more suitable site for this post. Sorry for the post.

You've got me wrong: Your question is fine. But what you've asked in your last comment ("which of these services are included on average by most network operators") would be off-topic here.

The reason for this is because airplane mode is on.
Turn off airplane mode, and all those settings will be available.

How to associate alternative app to stock Gallery app when launched from stock Camera app
I am running Android on a Samsung Galaxy SIII Neo (Android KitKat 4.4.2). I would like the stock Camera application to launch a different application than the stock Gallery application when the small square icon in the upper-right hand corner of the camera screen is clicked. Presumably, the stock Gallery app is opened via an intent, and I would like to associate a different app with the intent used to open the stock Galley app from the Camera app. I tried going to Settings -> General -> Application manager -> ALL and for both the stock Camera app and the stock Gallery app it says that there are No defauts set.
The reason I would like to launch another app instead of the Gallery app from the Camera app is so that I can use an app capable of adding EXIF data (which would allow me to enter EXIF memos alongside any picture's EXIF data).
How can I accomplish this?

the answer is you can't ,because the "preview" button action is hard coded in the stock camera app as a link to the right activity in the stock gallery app it sends an intent with the path to the jpeg image to the stock gallery ,the link is not an intent that can be received  by third party apps ,even if you try deleting the stock gallery app the preview button will have no action and in some phones your camera app will force close.

This is a bit dumb in my opinion. Why didn't the developers make the underlying intent behavior more general? Also, how hard would it be to download the code for the Camera app and modify that line that sends the intent. Is the Camera app distributed via a GPL license, and where can I find the code? Thanks.

yes ,I never thought of that before but now I see that this is dumb ,for the source code it depends on your phone and witch Rom/firmware you're using ,usually camera app is not delivered under GPL license but there is exceptions (if using Cyanogen roms all apps are under apache 2.0 and the source codes are available )

Thank you for your comment. Now I would like to submit a request to the Samsung developer team for this feature, but unfortunately all I could find was the Android Open Source Project Issue Tracker which is not specific to Samsung or Samsung Galaxy devices. Do you know where I could submit my request? Thanks.

You're welcome my friend there is two web sites of samsung's
1 / the open source project all open sourced stuff can be found here http://opensource.samsung.com/
2 / the developers website http://developer.samsung.com/
you can use the contact form on the open source website or use the forum on the developers website

Yeah, there's this site, but where is the page for software enhancements developer requests? Thanks.

I edited the last comment with the two links (I always tap "enter" which submits my comment before I want that :D sorry

Yes but your first link is for developers who program to the Samsung API. I want to reach developers who code those apis as well as the stock applications so that I may make suggestions. How can I do this? Also, not all samsung stuff is open source, or is it (I know it's not GLP, but not sure if all Samsung stuff is Open Source). I was able to find the files for my Samsung Galaxy SIII Neo GT-I9301I_EUR.

the source you found are kernel source code since it is under GPL V2 they have to put the sources public ,and some open source libraries ,submitting a feature request will take time if it was accepted (samsung is not realy that open to suggestions ) I advice the use of a third party app as a camera with the wanted option included in it or may be post a request on XDA forums may be some rom cooker will do the work for you or you can use apktool to decompile the camera apk and then made the changes you want to it.

If I decompile with apktool I would have to edit binary or assembly code right, I guess that's hard to do, not really feasible IMHO. And I'm not sure XDA developers would care about apps, perhaps the Cyanogenmod people, or perhaps developers on Google Play. Thanks.

if you decompile with apktool ou will have to edit smali codes witch is pretty readable if you are familiar with java ,and you will have all the .xml files readable. any way this is all I can do to help have a nice day/night

What is meant by "RAW" firmware?
I want to use Asus Flashtool to restore stock firmware to my phone. The download page says I will need "RAW" firmware. What exactly is that? I have already downloaded the correct firmware file from Asus' own website. The site in question has a link to what it refers to as "RAW" firmware, but I would rather flash the firmware I've downloaded from an official source. Is there any difference? Is "RAW" firmware supposed to be something special?

RAW is just the archive format used by the Asus flasher (as opposed to ZIP, EXE, IMG, KDZ, etc.). If you're using the Asus flash tool (AFT) and you downloaded a .raw file, you should be all set. AFT does not support other formats.
If you want to install the stock firmware as it comes from the official source (Asus website), then you wouldn't use AFT. The exact procedure you would use varies depending on what you've got installed now and if it will boot.

I didn't download a any .raw file though. The official firmware file is a .zip file (if extracted it gives a number of files and folders.) I suppose I need to download the .raw file. But where can I get it from a reliable source?

You posted another question about how to flash back to stock. Since this question is just about RAW, I've answered that here and will attempt to answer the other question separately.

Chrome stuck at loading upwork.com
When I go to upwork.com the page loads. However, when I click the login button it gets stuck loading.
Image: https://i.sstatic.net/wbUeB.jpg

What's your question? TBH this sounds like a bug in the website you should raise with the website owner.

@DanHulme you're correct.

Try clearing the cache and app data. Go to settings --> app manager and find google chrome. Then force stop google chrome and try again.
Try installing Google Chrome Beta (Could be a bug in the current version)
As @TamoghnaChowdhury said, it could also be a website or internet problem if it doesn't load on other phones.

I cleared chrome and app data, problem still persist.

It worked when I installed Google chrome beta on my android, thank you a asloss.

Glad you got it working, I'll edit my answer to account for that!

Do other websites load normally? I guess they do. Hence, this is a probably a problem with the website, not with Chrome or Android. Be patient and try again later.
Re: About it working with Chrome Beta, it could be any number of other factors related to the website other than Chrome.

it could easily be a bad plugin from that chrome version. but yes i would agree about it potentially being a website error.  he should have seen if it loaded on other devices at the time.  No worries though because it is working now :)

@asloss, You should know that Chrome on Android doesn't support plugins, and had never done so, so that is a moot point. Also, he most probably didn't bother to check the website on any other device, so I would say he got lucky.

Not what I meant by plugin (Although plugin is the wrong word I will admit), but yah sorry about not referencing you, I just figured since the answer was already marked I would put it in there for future readers. Didn't know how to cite, whoops

why HTC wildfire phone deleted all of my sms for 2 times?
my HTC wildfire phone deleted all of my sms suddenly. I don't know what happened!!
and I hadn't made a backup of them. what can I do to restore them?

It's a known bug in the Android OS. There is nothing you can do about it but bump your head. I'm moving over to  iOS because of that. There are many other bugs in Android, but this one is a deal breaker for me.
Here is a link to the official bug report. The issue has been known to Google at least since 2009:

(other comment transformed into an answer) Please note: This problem is probably caused by bad flash cells. The used database solution on Android is SQLite. iOS also heavily relies on SQLite (including SMS storage). This kind of problem will happen on your new iPhones too at some point probably. Do backups.

If you are using the stock messaging app, the settings might be the cause of the trouble.
Go to Messaging app -> Settings -> Untick Delete old messages. (If it was ticked I'm sure that was the reason for auto deleting of the sms)

There are two moments. 1. Default setting is to save all messages an do not delete oldest. 2. Messages are deleted not all, only oldest. So this isn't the case of topic starter.

In my default setting on Gingerbread the option was ticked and all my messages were deleted as a result of not using sms for quite 10 days. The setting depends on the ROM the user is using. But in this case I might be wrong, but it has occured.

Someone posted a logcat snippet of the occurrence in this bugreport:
I/Database(9): sqlite returned: error code = 11, msg = database corruption found by source line 54710
E/Database(9): Removing corrupt database: /data/data/com.android.providers.telephony/databases/mmssms.db
E/DatabaseUtils(9): android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed

Explanation of the above:

SQlite is the used embedded database engine on Android. Error code 11 describes a malformed database disk file (#define SQLITE_CORRUPT 11 /* The database disk image is malformed).
A bad db file was detected, removed and a new empty one created
All SMS are gone now

Some further thoughts:

SQLite is known to be extremely well tested (99.9% of all code are test cases)
Therefore it's highly probable it's not SQLite which causes this
Very probably the file got corrupted by bad flash storage cells, memory corruption or another reason

You can do some things. I'd suggest the following order:

See again if you do have a backup. If so restore it.
You could take your phone to a forensics / data rescue expert like Kroll Ontrack and have it analyzed.
There's also growing free support for mobile devices, eg. by Sleuthkit
For the future: Back up your SMS data, e.g. move them to GMail

Some final words:
SQLite is very common for embedded devices, iOS also relies on SQLite for many things (including SMS storage). There will always be a chance of losing data if you don't backup: Device is lost/stolen/broken, dying flash storage cells, software bugs, other erratic situations like full storage, etc. It's the same with any device, don't rely on a single point of failure, have a backup in the cloud. This just works with mails, your address book and so on. Do the same with SMS.

Nothing. You can do nothing. One option is go to data recovery service, but price will be uninteresting.
Also tell please if you install 3rd party software on your phone.

why HTC wildfire phone deleted all of my sms for 2 times?

I suppose that there can be installed glitchy or malicious programs on phone. Also if you have child or children, they may have played with phone and occasionally deleted messages.

I don't know... Somebody likes to press downvote for every answer. Some kind of terrorism :-(

This has happened to me multiple times before. Each time the number of messages was around 6000. I think there may be an upper limit on the number of messages the Messaging app can handle, and beyond that it just deletes everything. I might be wrong though.
I don't know of any way to recover the messages though.

You're really asking two questions here, and both are extremely hard to answer. First of all; why did the messages disappear? We can't possibly know this because we know nothing about what software you're running, if you changed something (installed/removed software etc.) around the time the messages disappeared and so on. Maybe it's a "feature" of the stock software?
The second question is; how can the messages be restored, and that's a very hard question to answer because what you're asking about is data recovery which is not exactly easy work usually (that's why it will cost you a lot of money to pay someone else to do it). You would need to make a copy of your entire storage first of all, and then go in and look at the raw data to perhaps salvage all or some parts of earlier messages.
In short, if you care a lot about some messages, you should have them backed up to begin with. You can either do a backup of your phone, or copypaste the messages into a platform in the cloud (Dropbox, Google Docs, you name it).
I'm sorry to say you won't find a solution to this problem without either paying a lot of money to get someone to recover your data, or start reading up on data recovery yourself and learn how to copy all the data from your phone bit by bit and then looking at the raw data.
I wish I could have given you a better answer, sorry about that.

Android update on HTC Desire 628
I'm looking into buying an Android phone, and quite like the specs and looks of the HTC Desire 628. Unfortunately it ships with Lollipop (5.1). Would it be possible for me to upgrade this device to Marshmallow (6) or Nougat (7)? If so, how?

For a phone of this popularity you can only expect something to drop officially, the chance of which is slim (especially in regards to Nougat). Decide what's your priority (aesthetics VS updates) then choose wisely.

send fake accelerometer or multitouch signal to an application on Android x86
I have this challenge:
I use proto.io to make demos of application I will develop, but this time I have to run it on a PC running Androidx86, connected to a touchscreen (no multitouch). Proto.io requires at startup to tap the screen with 3 fingers or to shake the device, obiouvsly I cannot do both as the PC don't have an accelerometer.
Is there any way to send a fake shake or multitouch to the app? I have already contacted the support team of proto.io, but they confirmed that right now there is no other way to start the application..
Any idea?

Solved, this can be done using app WIFI ADB - Debug Over Air installed in the device, after establishing a connection sending the command

adb shell input keyevent 82

to shake the device.
Another solution I found was using app Tasker to send a shake.

Does rooting a phone expose the phone to security risks?
I have a very simple question. If I root my phone, will it be easier for malware to run on my device and cause more damage (due to the nature of the extended set of operations that applications with root access can perform, and the downside of being logged in and running applications as root on Linux systems).
Thanks.

EDIT:
Even when an application is rooted, it can still be configured to disallow installation of APK files from unknown locations (locations other than the Google Play Store). This increases security since it makes it impossible that a web browser download install a malicious app even though the device is rooted.

Yes and no.
If you carelessly install apps to your phone without reviewing permissions, then yes your system is more vulnerable to malware and such.
But if you "read the fine print" and are conscientious about what you install, then no your system should be just as safe as not rooted.
You can also control permissions with the native AppOps or you can use a third party app. A excellent example of that would be My Android Tools. You can enable/disable Activities, Broadcast Receivers, Content Providers, and Services. So even if an app has an undesirable permission you can still control what your apps, while rooted, are doing (even in the background). Not only can you change the settings for user apps, but also system apps. It even has an option to backup the settings before any changes are made, in case of any issues.
Once rooted the Android becomes very interesting. The sky's the limit.

If you don't have AppOps in Settings (because its a hidden setting) you can download a shortcut to it from the PlayStore. There are several apps to accomplish this, just pick one you like.

Thank you for your answer. I looked for the AppOps application under Application manager -> ALL but couldn't find it, so at least on my Samsung Galaxy SIII it does not appear to be a "native" application. However I can see several results for AppOps in Google Play, not sure which of these applications is the best. Thanks.

According to this article, on newer Android phones it is also possible to enable/disable running processes by clicking on an application in Application manager from settings and then clicking on the Disable/Enable button, but my Samsung Galaxy SIII (Jelly Bean 4.3) has an Uninstall button in that very position.

Application manager: no SD card present but applications still listed under "SD CARD" and what is USB storage?
The back of my Samsung Galaxy SIII has a slot for inserting an external memory SD card (MicroSD up to 32 GB) next to the SIM card slot, but I never purchased nor inserted any, just double checked just in case. However when I go to Settings -> More -> Application manager and swipe once to the right the following screen shows up (click to enlarge):

As you can see, it looks as though I've downloaded these applications to an SD Card despite the fact that such SD Card on my system does not exist. Can someone be so kind as to explain what this screen is displaying? Perhaps internal storage and internal memory are both synonymous with internal SD, but I'm not sure and would like clarification. And if this were true, then is this screen displaying applications stored on both the internal as well as the optional external SD card, or just the internal SD card?
Thanks.
Also, what is the gray rectangular area just below USB storage at the bottom of the screen for? My device doesn't have any USB sockets despite the one at the bottom of the device used to recharge the device or transfer files. What is this USB storage? Does the SD card appear as a USB device? Perhaps the external SD card when present appears to the Android OS as a USB device. If not, then what does USB have to do with this screen?
Thanks.

EDIT:
I just checked this information on the Samsung Galaxy S Plus. Here is a screenshot of
the breakdown of storage which is broken down among internal phone storage (and personal data which seems to me at least like it's the same thing), internal SD card, and external SD card. So, my guess is that not all phones are the same. This screen was accessed by long-pressing the Home hardware button, clicking on the Task Manager button, and then clicking on Storage.

As the following screenshots demonstrate, on the Samsung Galaxy SIII the only internal storage present is an internal SD card (which is 16GB as advertised).

OTOH, on the Samsung Galaxy S Plus, as we have seen there are two separate kinds of internal storage, namely internal phone storage which must be a device-specific format, and internal SD card.
On the Samsung Galaxy S Plus, when one goes to Settings -> Applications -> Manage applications one can see the difference between All and On SD Card. This phone did not have an external SD card at the time the following screenshots were taken, and we can see that only some applications (all of which are user downloads), have been installed on the internal SD card (as opposed to on the other internal memory):

The Samsung Galaxy SIII also displays different tabs when one goes to Settings -> More -> Application manager and one can swipe left and right to switch from one tab to another, and the available tabs there are named DOWNLOADED, SD CARD, RUNNING, and ALL. The ALL tab, which includes the applications under DOWNLOADED plus preinstalled apps, however, still contains more applications than can be seen under SD CARD (the SD CARD AFAIK lists applications available in the internal SD card, not sure about external SD). This puzzles me, because I thought that on the Samsung Galaxy SIII the internal SD card was the only available internal storage medium. Screenshots follow:

On the Samsung Galaxy S Plus, both applications installed on the internal phone storage location as well as the applications installed on the internal SD storage location when viewed by clicking the application in Settings -> Applications -> Manage applications -> All / On SD card have a button to move the application to external SD storage labeled Move to SD card and since I don't have an external SD card such button returns the message Failed to move application. Not enough memory:

The same layout is also available on the analogous screen on the Samsung Galaxy SIII. Here are two screenshots shown when I accessed two applications in the analogous manner by clicking on Settings -> More -> Application manager -> click on any application to view its info`:

On the above screenshots I don't get the difference between the fields Data and SD card data, since what I thought I had understood was that there is only one internal memory location, and I do not have an external SD card on this device. Again the Samsung Galaxy SIII where I tried this had no external SD card. On the screenshot on the lef, the Move to SD card is properly grayed out, which I take it to mean that for some technical reasons the application cannot be moved to the external SD card. On the screenshot on the left, the technical details of the application make it possible to move it to the external SD card, but since no such card is present clicking on the button yields the message Your phone does not have a SD card. Insert SD card..
on the Samsung Galaxy SIII, unlike on the Samsung Galaxy S Plus where clicking the button gives an alert error message.
However, what I find strange on this Samsung Galaxy S Plus is that there does not seem a way to transfer an application from internal phone memory to internal SD card memory (at least not via Android OS's GUI, maybe it is possible if the filesystem is mounted and then files are copied with command-line tools such as Unix cp). After all, the internal phone memory is not read-only as I have installed some applications from Google Play Store there as well. Probably, the excutable .apk files which get installed contain preferential information as to where they want or prefer to be installed once downloaded.

EDIT:
Still, I don't get the USB storage bit (seemingly however empty on the Samsung Galaxy SIII), which shows up on both the Samsung Galaxy SIII and the Samsung Galaxy S Plus, as the above screenshots demonstrate.
As we can see from an above screenshot, on the Samsung Galaxy SIII, no information is given on USB storage (the gray rectangle at the bottom of the Application manager -> SD CARD (USB storage) contains no numbers indicating what percentage of USB storage has been used up). Also from the above screenshots, we can see that the Samsung Galaxy S Plus reports roughly 5GB of internal SD card storage, of which Settings -> Applications -> Manage -> On SD Card reports a breakdown of roughly 400MB used and 4.6GB free from which it seems possible to conclude that on the Samsung Galaxy S Plus USB Storage is synonymous with internal SD card storage, however bizarre that may be.

I don't even have an SDCard slot on my device, and the main folder on mine is "sdcard".

I think the internal storage space looks like an SD card to the operating system, whereas for those devices that can accept external storage, this comes as an SD card, but according to my screenshot may look like a USB stick. But I'm really not sure. Would you be so kind as to post some screenshots? Try holding the power button and the home key together to take the screenshot, then upload it. Thanks.

possible duplicate of What's the difference between "sd card" and "usb storage"?

Apps shown in the "on SD card" tab aren't actually on the external SD card, they're just apps you are able to move to the SD card. If they'd been on the SD card, the checkbox next to them would've been checked with a colored check mark.

It's true. Looks like you're right. Applications shown under Manage applications -> On SD card tab (Samsung Galaxy S Plus) or under Application manager -> SD CARD (Samsung Galaxy SIII) are simply those applications which can be moved to the SD card: they all have their Move to SD card button enabled. Other applications listed under ALL which are not listed in this section are for technical reasons incapable of being moved to an external SD card and (thus) do not appear in this list. Thanks!

I still haven't figured out the following: why does the USB storage bar displayed under Manage applications -> On SD card on the Samsung Galaxy S Plus display usage statistics for the internal SD card, while the same section at the bottom of Application manager -> SD card on the Samsung Galaxy SIII tab displays no numeric information? Also, is USB storage on mobile phones always synonymous with internal SD card storage? Thanks.

@JohnSonderson the no numerical information I don't know about, since I don't have a Samsung device. It may be a bug, or Samsung designed it that way. Also, USB storage nearly always refers to internal /sdcard/ partition

OK. Thanks. This information is very useful. What about external SD storage, does it also fall under the category USB storage or is it only the internal SD which shows up as such? Could you please post a screenshot of the Application manager -> SD CARD section on your device. I am curious as to what your device says about the USB storage. You can take a screenshot with Power+Home key or Home+Back or swipe your hand across the screen on several devices. Thank you for your information. I really appreciate it.

Also, what happens if you mount an external USB drive onto the Android phone (I presume this could also be a possibility if the USB drive had a small enough adapter). Thanks.

@JohnSonderson if you mount an USB drive using an USB OTG cable, it will be mounted at /mnt/usbdisk. I don't know what that will be called on the phone though

Thanks, and what about mounting a regular external SD card (by inserting the card, without going through USB cable)? Will that storage also show up as USB storage or not. Where does it get mounted on the filesystem? And would it show up as USB storage in the user interface? Thanks.

@JohnSonderson it will show up as external SD card, and IIRC it'll be mounted at /sdcard/external_sd/. I'm not sure of the behaviour if you mount yet another card, via an USB SD card reader though.

Thanks. As to the filesystem I found out from this link that /sdcard is always a symlink to /mnt/sdcard. Samsung Galaxy SIII device there is also a (likely custom) partition called /storage/emulated/0 which is the Home directory of the File Manager application from Cheetah Mobile on Google Play (probably the same as cd ~ at the shell prompt) and after examining its contents this also seems to be a symlink to /mnt/sdcard. On the Samsung Galaxy S Plus /mnt/sdcard is the Home directory of the File Manager app.

As to the external storage the Samsung Galaxy S Plus has /sdcard/external_sd and doesn't have /mnt/usbdisk. On the other hand /sdcard/external_sd doesn't exist on my Samsung Galaxy SIII, although this device has six USB directories called /mnt/UsbDrive{A,B,C,D,E,F} and it is presumably these which are used for mounting USB drives via OTG cables. So, my guess is that unless a directory appears in the link I posted, these mount points for the external SD card and OTG USB drives are not standardized and relying on these locations in computer programs is thus unreliable.

Also because of these differences, I was not able to conclude whether in the graphical user interface of Android devices, external SD cards and OTG USB drive also fall under USB storage. Please let me know. Thanks.

@JohnSonderson Generally, the naming convention of the UI is as follows: /sdcard is USB storage, internal memory is /system, SD card is the external SD

Could you please elaborate on the following: from the GUI it seemed like on my Samsung Galaxy SIII the internal storage was the SD card (I didn't see a separate ROM/internal space). So on such a system the /system directory would also be classed as USB storage. Am I correct?

@JohnSonderson /system would most definitely not be classified as USB storage. I think this thread should end, maybe someone could create a chat room. Also, I don't have access to a Samsung device, and my knowledge is only finite

Let us continue this discussion in chat.

battery draining when developing
I am connected via an USB port and have the screen constantly on, with the lowest brightness settings - by using the Lux app, that lowers that below the allowed level, making the screen barely visible.
Nevertheless, the phone is discharging fast.
Nexus 5 stock rom, rooted.
Only one process running in the foreground (an official play store app) which I am trying to automate via adb.
This didn't happen with a chinese MTK tablet, which stayed 100% charged all the time.
What can I do to work around this issue?
Thanks.

How about underclocking cpu speed. since the device is rooted. or you can check other services that may not be usefull but running background.
if you have busybox or something installed. maybe you can look for processes and their consumption of cpu.

One of my phone's last location is in different continent
today, on my Google Account, I saw that one of the last locations of my phone is from the USA when I live in Europe? Is it right?

If you haven't been to the US recently and haven't used a VPN connection on your phone, this is not right. The first thing I would do in this case is to change your Google password.
Maybe go through the Google security checkup, some good advice on there: https://security.google.com

Play audio through phone speakers when connected to Bluetooth car
My car has Bluetooth for making / receiving calls. It also allows media playback if I switch to Bluetooth instead of USB. I use my phone for sat nav so I'd like to be able to hear the audio telling me which direction to go and of any traffic problems. The issue is that it routes that audio to the car and I can only hear it if I switch the stereo to Bluetooth media, as if I was going to play songs from the phone. That means I either can't listen to music on my USB or I can't hear the sat nav. Is there a way to get my phone to play the audio back through its speakers in n steal of through the Bluetooth but still allow phone calls through Bluetooth?

This seems to be the setting -- go to Maps' Settings (tap the three lines in the left top corner to open a pane, then tap Settings there), there go to "Navigation Settings" and turn off "Play voice over Bluetooth" switch.

Go to Bluetooth settings, click on the gear icon beside the car name, uncheck audio.

On my Samsung Galaxy S4 (Lollipop) using Samsung Music (recently updated, but this was the case when I bought the car, before the Lollipop update, and immediately after that update as well), with a 2015 Ford Fiesta (basic Sync Bluetooth audio and controls), this is the default.  When I'm playing music, either Verizon Navigator or Google Maps directions (if set to give voice directions) pauses music playback to speak through the car's sound system.  Even if I'm listening to FM radio, the broadcast is interrupted for directions.  If I'm on a phone call, the directions voice is mixed, much softer than the voice of the person I'm speaking to (but still there).
Other phone initiated sounds (notification, for instance) also pause music, though keyboard sounds don't.  Car initiated sounds (low fuel warning, service required warning) pause playback as well.
If this isn't happening with your phone and your car's Bluetooth, I'd start with checking your phone's general settings, then those of your navigation app, and finally those of your car's Bluetooth and sound system.  It's got to be in there somewhere.

How to log all user interaction on my device?
I would like to know whether on an Android device it is possible to:

Log the date and time of every time a password is entered on my Android phone (this security measure would mean that if someone in my home sees me enter a password without me noticing it, and then uses it to log into my phone, I would then be able to see whether this happened or not to take care of my suspicion).
As an extra step, I would like to log all activity once the login screen is bypassed as well (for instance the date an time and application name for each time an application is opened. This is because, while my phone is password protected, once I make the screen go blank by pressing the hardware button on the right, some time goes by until a password is required: I have things set up this way so that I don't have to enter the password just so often). So, is there a way to log all user activity when the lock screen has been bypassed as well?

The device I have is a Samsung Galaxy SIII Neo running Android KitKat 4.4.2.
The device has been rooted.
Thanks!!!

A bypass technically is a mockery of the security of a particular thing for which bypass has been used. In your second case, I see no scenario of bypass. It's just a user (not you) entering your password and gaining access in a technically legitimate manner. Please explain what kind of bypass scenario is supposed to be considered in second point. How do you technically differentiate between your access and the other person's access to the system? I currently find no difference.

Also see How do I know when an app was used in Android?

@Firelord, if I leave my phone on the table, and know I didn't touch it in the last 8 hours, and go back to it and see that a password has been entered correctly (1.) and that some applications have been opened (2.), then I know there has been an intruder accessing the stuff on my phone. No, I don't distinguish between myself and someone else. I just happen to remember when I last personally interacted with my phone.

@Firelord, I've tried following the instructions in your link, but it does not work on my Samsung Galaxy SIII Neo. The error I get is that there is a connection problem and that the code I entered is not valid.

John, in that link I also mentioned alternative way using ADB. Does that also not work in your device?

Well, for one I cannot get to the Testing window, is there some other code I need to type on my Samsung Galaxy SIII Neo KitKat to get this to show up. Secondly, when I am on vacation I don't usually bring my computer with me, so I cannot really rely on using 'adb shell' to get to the last time, especially since I may use the app after someone accesses it, and this would overwrite the last time with some other time, not desirable.

I'm wondering if I could have an app built (e.g. on freelancer.com or elance.com) to support the behavior I'm looking for, or whether what I'm afeter is impossible to carry out. Thanks.

How to transfer Firefox bookmarks (and saved logins, etc) from one phone to another **without** using Firefox's "sync", 3rd-party apps nor root?
Title says it all, pretty much.
A quick Google search (surprizingly) did not return any pertinent results.
I guess it might boil down to copy-pasting some system folders/files from one Android installation (via USB-C, via a PC) to the other. But I prefer not to be the guinea pig here...
(PS: I'd rather not have to revert to Firefox's "sync"-feature for various reasons... anyway, it's obvious that "sync" would work, but that's not the question here...)

EDIT:

My phone(s) aren't rooted.
Neither a 3rd-party app, nor a cloud-based solution is what I'm interested in.

Related link(s):
seems like the transfer-via-USB-route would require a rooted phone :(

How can I access the folders where Firefox mobile stores its application data
https://support.mozilla.org/en-US/questions/949785

Does this answer your question? Export Firefox Android Bookmarks to html file

@beeshyams Not really; I can't imagine saved logins (incl. passwords) could be simply dropped into a flat html file (securely) for migration from device A to device B...

I wrote how to do this for bookmarks (without meta data unfortunately) in this answer:
https://android.stackexchange.com/a/256203/407146

As of now, given the constraints, you cannot achieve what you have set out for.
Firefox app would be able to restore bookmarks using these methods,  in the absence of a hack:

native settings option to import bookmarks. This is not available in Firefox for Android as of now.
Using Web Extensions/ Addons. Firefox for Android doesn't provide API support for manipulating bookmarks as of now.
Read and write to its browser.db database using a universally accessible content provider. Firefox's content provider for this is not accessibly by any user other than Firefox itself.
Full participation in Android Backup Service. As a result, a user can use adb to backup and restore Firefox app's data. Sadly, Firefox explicitly disallows backup as of now, so adb is also out here.
Using its own implementation of cloud backup service. It does provide a sync service -- but then, you don't want that so this is also not an option anymore.

Possible hacks:

copy and then restore the browser.db or into your another phone. That database contains users' bookmarks. Alternatively, use a root backup/restore solution, such as Titanium Backup.
Use content provider with root access to read and write into browser.db. But if you have root access, "1." is plain and easy.

As you can see from above, your options, as of now, are: get the devices rooted, or use Firefox's sync services.
Third option is to raise a feature request with Mozilla to provide bookmarks import, and extension support for manipulation of bookmarks.

I recently migrated app data from multiple Firefox apps from one Android phone to another. At first I tried to rely on Android's device-to-device backup transfer mechanism, but that did not migrate any meaningful Firefox data. I also tried adb backup, but that does not work either (bug 1808763).
What did work is to enable Firefox's remote debugging feature (about:debugging to connect to an Android device) + adb (no root required) to unlock the ability to execute arbitrary JavaScript code in Firefox's main process on the Android device. This enables me to do anything what Firefox is allowed to do, including reading and writing its app data. Which is exactly what we need to create and restore a backup.
The remaining part is the code to actually perform the copy and restore, which I shared at:
https://github.com/Rob--W/firefox-android-backup-restore
Backup instructions: https://github.com/Rob--W/firefox-android-backup-restore#backup

The backup instructions are designed to not consume any space on the source device. The first step is to start a TCP server on your computer to receive the data directly. If you don't have nc (netcat) available on your computer, an alternative is to run a local TCP server on your Android device and then use adb to retrieve the data from it:
adb shell 'nc -l -p 12101 > /sdcard/firefox-android-backup.tar.gz'
adb pull /sdcard/firefox-android-backup.tar.gz
adb shell rm /sdcard/firefox-android-backup.tar.gz

Once the server has been set up, follow the rest of the instructions to run fab_backup_create();

Restore instructions: https://github.com/Rob--W/firefox-android-backup-restore#restore

The first step to restoring is to put the backup archive on the device (replace org.mozilla.firefox if NOT using Firefox release!):
adb shell mkdir /sdcard/Android/data/org.mozilla.firefox/
adb push firefox-android-backup.tar.gz /sdcard/Android/data/org.mozilla.firefox/

The default instructions are for Firefox release (org.mozilla.firefox), but if you want to restore to a different app, replace org.mozilla.firefox with:

org.mozilla.firefox - Firefox Release
org.mozilla.firefox_beta - Firefox Beta
org.mozilla.fenix - Firefox Nightly
org.mozilla.focus - Firefox Focus

Once the backup has been uploaded to the device, restore it by following the rest of the instructions to run fab_backup_restore();

I have tested this with all Firefox apps (versions 118 - 120), on Android 12 and Android 14, on Google Pixel 3 and Google Pixel 8.

How to silence all but one application? (no calls, messages, notifications and similar interruptions)
When listening to meditation instructions (previously downloaded as *.mp3 files) I would like to be able to silence all applications, (that is, all audible notifications, messages and calls). How?

PS: Native solution(s) which are not reliant on 3rd-party apps are prefered.

At least related: Is there a way to set app-specific volume? / Control volume of particular app

Android version?

@Firelord kitkat.

If you don't want to use any 3rd-party apps, then you have to learn programming and make your own.
In my opinion, the best way to do this is using AutomateIt.
Its normal features include "Set volume" actions and if you register an account, then you could download one Pro codec, like the "Multiple(OR)" event that, could also be used when more than one app are opened.
All types of volume can be changed when a certain event happens.

How to disable shortcut to launch (Samsung's) S Voice *without* accepting its ToS?

By default, when you double-tap the home key, you'll launch straight into S Voice.

To disable that shortcut, one could

load S Voice, then press the menu key and hit "Settings." Next,
  uncheck "Open via the home key." That's it -- with the shortcut combo
  disabled, the home button should respond immediately as opposed to
  with a very slight delay.

However, this method seems viable only once Samsung's Terms of Service (ToS) have been accepted - only after which S Voice will launch fully. Any way to disable that key combo without having to accept ToS of a S I do not want?
Note that at this stage I do not (yet) want to uninstall S Voice. If you happen to know how to uninstall it, I'd appreciate a comment, though :-)

I just disabled S Voice entirely for now, as explained here and elsewhere:
Application Manager >> All >> S Voice >> Disable, then reboot.

Is it safe to delete "Miscellaneous Files" of WhatsApp?
Based on an earlier Q&A, is it safe to delete "Miscellaneous Files" of WhatsApp?
"safe" as in that it won't delete anything you might regret deleting (like photos, etc which haven't been backed up elsewhere).
--- click image to enlarge ---

Doesn't your Android list the files/directories accounted into "Miscellaneous files" when you tap on that entry?

@Firelord No, it does not.

Downvoting without explaining why is not all too helpful.

No, it is not.
If you want to clear storage space on your internal storage, you may copy-and-paste your WhatsApp media folder to another place, like your SD card; then delete the folder's contents...

How to change the pitch of the white-noise ***when placing a call*** with Samsung S10e connected to the Bose QC35ii?
Background
Ok, here goes:
Huawei P10 is still the best phone out there. (Only thing I miss here is an additional wide-angle lens, but hey.)
After having taking it's ten-thousandst fall the glass splintered slightly on the side and the camera is showing focus issues (which can only be "fixed" temporarily by letting it drop on a flat surface: google it...) I decided I need to look for a replacement :(
Regarding modern phones, I can't stand a notch, with the exception of the punch-hole on the side, like featured in the Samsung S10e. Thanks to Trump and the Huawei-Google-sanctions, the obvious Huawei P40 family is also out of the question.

The Problem
Hitherto, I'd use the P10 in combination with a Bluetooth-connected Bose QC35ii headset for business calls. Sure, there was a distinct white-noise hiss already then when initiating calls, but now this hiss with the S10e has a different pitch and it's driving me bonkers / bananas.
Note:

All devices have the latest firmware and updates installed (as
per 20 Apr 2020).
No (white-noise) hiss is present when placing a call with another, USB-C wired
headset
or without a headset.
The hiss starts already when dialling and continues throughout the call.
Listening to music does not cause any (discernible) white-noise (irrespective of whether noise-cancelling is on or off).

Does anyone have an idea of how to change the pitch of the white-noise when placing a call with the Samsung S10e through the Bose QC35ii?

Related Link(s)
https://community.bose.com/t5/Around-On-Ear-Headphones/Bose-QC-35-Firmware-4-5-2-Noise-Cancellation-Investigation/td-p/285738 (interesting read, albeit not that helpful... doesn't cover a way to turn off the "hiss")

@downvoter: care to comment?

I haven't voted (yet), but the rant doesn't make the question anything easier to answer. Care to reduce your personal opinion/rant and stick to the fact & issue only?

@AndrewT. Fact is: Huawei P10 had a much more pleasant (to me!) "hiss" than the Samsung S10e when calling via the Bose QC35ii.

I happen to own a S10e and QC35II as well. Before I had the QC35 (version 1) and never had issues with the bluetooth. Everyting was running smooth, I had my phone and PC connected to the headset at the same time all the time.
It started with the QC35II. I cant say anything about calling with the headset, but I recognize the interference with listening to audio. Things that helped between phone-headset connection where going to 'Settings' -> 'Connections' -> 'Bluetooth' -> Next to your connected QC35 headset press settings symbol -> There are three options, turning 'Calls' and 'Acces to contacts' off helped (so leaving only Audio on).
As for desktop, go to Configuratiescherm\Hardware en geluiden\Apparaten en printers\ to properties of connected QC35II, tab Services and unselect Handsfree calling.
Third thing that helps with less interference is turning off my phone bluetooth when the headset is connected to my PC and vice versa.
You can see my tips are focussed on listening to music, however it probably works the other way around as well --> turning off audio and leaving on call-things will cause less interference for calling.

Unlocking Bootloader of HTC One X on Windows 8.1 / Linux Ubuntu
How to unlock the bootloader of HTC One X on Windows 8.1? Since I want to install MIUI Rom.
When I install the latest version of "HTC Sync Manager", It shows me that the Windows 8.1 is not competible with this software. Therefore, the command fastboot oem get_identifier_token does not work because of the incompatible HTC Driver.
I am wondering whether I can unlock my HTC One X on my Linux Ubuntu? If yes, how to do it? Do I need to install HTC Driver on Linux Ubuntu?
Thank you for your attention.

Linux is absolutely the best way to do this sort of things. This is a thread on xda about how to set the development environment on Linux Ubuntu in particular http://forum.xda-developers.com/showthread.php?t=2302780
Follow these steps and you'll have fastboot command set up to do the unlocking process. Plus you won't need any driver to let the system recognize the device.

How do I enable birthday reminders or view birthdays as events in Calendar on Nexus 4
Simple problem: I forget the birthdays of my friends. I have the dates saved in my contacts (CardDAV-Sync address book) and can view them with the People app. I have not found a way to set up an alert or reminder, though. Alternatively I'd like to see them as events in Calendar. I would hope there is some option in the stock Android 4.3 of my Nexus 4 to configure this, but if it is not possible, do you know of a simple reminder app that does not ask for full internet access?
Thanks in advance.

Are you using Google Calendar?

Also, did you look in the Play Store? I see a number of apps which purport to send reminders or otherwise list your contacts birthdays.

@AlEverett: I'm using the stock Google Calendar app (version 201306302 if that is of any use) but only use my own CalDAV calendar datasets synced with my own Radicale server. I do not display or sync any of the Google calendar datasets (for the lack of a better word).

@AlEverett: Yes, I've seen those apps but they all suffer from feature creep and thus permission creep. I draw the line at full internet access, because I don't want them to be able to send my personal data to their servers. I've emphasized the passage asking for that in my question.

..., but if it is not possible, do you know of a simple reminder app that does not ask for full Internet access?
The topic is also discussed in the Google forum for the calender application and indeed there seem to be only workarounds.
There is also an app mentioned, which does provide the notifications for the birthdays and does not need Internet access: https://play.google.com/store/apps/details?id=de.noyer.consulting.contactevents.pro
That is a paid app for a small amount, but there is also a free version with Internet access for advertisements: https://play.google.com/store/apps/details?id=de.noyer.consulting.contactevents.free
If you just want to try the free version if it works for you, you could perform the following steps:

Download the free app in the Play Store
Turn your device into flight mode
Start the app
In Android 6 or higher: Grant access to adress book at first start
Check the app, widget etc. (Notifications are only raised at midnight)
Uninstall the app
Turn off flight mode
Decide if it worth to get the Pro version

The paid app costs hardly anything—so it makes perfect sense to buy it.

How to Add Your Gmail Contacts' Birthdays to Google Calendar

Add Your Gmail Contacts' Birthdays to Google Calendar
To add a calendar showing and alerting you to birthdays of your Gmail contacts to Google Calendar:

Select Settings | Calendar settings in Google Calendar.
Go to the Calendars tab.
Follow the Browse interesting calendars » link under Other Calendars.
Open the More tab.
Click Subscribe for Contacts' birthdays and events.

Sarah Dee's Answer on Why it's not possible to add notifications at Birthday's Calendar?

Please follow these steps:

Go to google.com/calendar so you are just viewing the regular home screen
On the left hand side under Other calendars, find Friends' Birthdays, click the drop down arrow and select Reminders and notifications from the menu
Under the Event Reminders section, Click Add a reminder, set the desired reminder
Click Save

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference (please [edit] your question and do so). Otherwise your question ceases to be helpful in case the link dies.

These guides only work for the Google calendar, unfortunately, and not for other calendar accounts, e.g. the caldav calendar I was referring to in my question. (I have no contact information stored in the Google account.)

There is not option to set event reminders fot the birthday calendar

In what reality is this answer even remotely correct?

This answer was probably correct at the time (2014), but now it is outdated (2018).

I couldn't find a native way either for that, and was wondering why it worked on one of my devices but not on the others. On the "working" device, I'm using aCalendar as a frontend to the Google Calendar, which also comes with a nice widget, and is really handy. aCalendar also sends birthday reminders, shows them on the widget itself and also puts a hint in the notification bar which is hard to miss. So until you find a solution you like more, this would be a possibility.

Thx. It also seems to have reasonable permissions. I'll look into it if there is no other answer.

Exactly those were my arguments when I chose it for my device: Handy, comfortable, light-weight, and "reasonable permissions" :) Good luck, further; I'll watch this question as I'm curious for "on-board alternatives" as well.

What does the "@" symbol in the Running Applications/Services mean?
What does the "@" symbol in front of the time given in the right column of Running Applications/Services mean?
See screenshot below.
Phone: Samsung Galaxy S4 (GT-I9505)
OS: 4.2.2

Screenshot (click image for larger variant)

What phone and Android version is this on?

Samsung Galaxy S4 (GT-I9505), 4.2.2

We have the same phone and Android version, but I haven't seen those symbols on my phone. Hmmm.

All my Nexus 4.3 devices don't show this either. Seems like it's Sammy specific (maybe even for some sub models only)

My 4.2 Nexus 10 gives an = sign on Google Services, but no @ signs.

I've looked in the source for this settings page in AOSP, but can't find anything relevant.

It means that the process has been running longer than 99 hours, 99 minutes, and 99 seconds. It's a formatting bug.
The second hour digit, after reaching '9', will simply continue with the next characted from the ascii alphabet:
0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~

Where in this case ':' means 10, ';' means 11, '<' means 12, etc.
For example, '<5:12:34' means 125:12:34 and '?5:12:34' means 155:12:34.
It's fixed in Android 4.3
The Related bug report is here: http://code.google.com/p/android/issues/detail?id=41401

I don't have a Samsung Galaxy S4 but based on the information provided it seems like this is the time frame since the services has been active (i.e. Service "com.sec.phone" started about 1:46:26 ago).
I can see that this is the case because a few other services have the same start time, at which point you either turn your phone ON (and Android initiated those services automatically).

Rooting Android Galaxy S2 - Connection Error
I am trying to root my Galaxy S2.
So I followed instructions online, I booted in debug mode, connected the USB cable then pressed the up powerbutton to start the mode, I then opened up Odin v3 3.04 and it showed up with a device connected. I selected the correct .tar file under PDA and clicked start. It says "setup connection" and freezes at that.
I tried redoing it because it wasn't working. Eventually I decided to see if it was just the program. I opened Samsung Kies and it couldn't connect. It tried connecting for a long time and eventually just gave up.
The weird this is that when I plugin the USB cable my computer actually recognizes it as a Samsung Device because the first time I plugged it in it installed drivers automatically using Kies.
I tried using different USB ports, tried using a different cable and I tried charging it.
I couldn't tell if it was fully charged but it charged for 8 hours so I'm sure it was charged fully. Still didn't work.
After researching for 2 days and trying endlessly, I decided to see what you guys think.
So let me know if you have ideas! :)
I tried uninstalling and reinstalling kies, now it is connecting with Odin but it wont connect with kies at all. But its now showing this error.

You might have luck installing an aftermarket firmware, benefit: Android 4.3 with constant updates.Which model do you own? http://wiki.cyanogenmod.org/w/Devices#vendor="Samsung";

I know its the sliding one, but its with Rogers and that link doesn't list any Galaxy S2's with sliders. It also doesnt have a button, it has touch buttons with 4 at bottom if that helps.

I followed this guide rooting mine:
http://forum.xda-developers.com/showthread.php?t=1773659
I started at Step 1. HOW TO INSTALL TWRP OR CWM : ON STOCK FIRMWARE OR CUSTOM ROMS - GB, ICS AND JB
The guide even has a section for troubleshooting Odin errors.
Be careful with odin. When you're editing your bootloader. You can brick your device if you do it wrong, and then your only option is JTAG repair, which will cost you ~$50

I used Google's Find My Phone to factory reset my phone since I lost it but before that happened, I got my phone back
So, I headed out one day and lost my phone. I head to see ways to get it back and saw that you can factory reset it through Google's Find My Phone. Now, someone gave it back and I'm stuck because if I go online on that phone, it may be factory reset. How can I prevent that from happening?

If you reset your phone using the Android Device Manager, there's a good chance it's already gone. Online means connected to the internet, and if mobile data was still on while you clicked the erase button, there's no way to undo that, as far as I know. Luckily, you can still recover some data when you sign in to your Google account on your phone, namely apps, settings and maybe some photos (if you used Google Photos).

I opened the phone and it was untouched by the person that got it. It wasn't connected to the internet since mobile data was turned off and I only used a laptop to tell Google to factory reset it, which it said won't happen as long as it is not online.

Using this, I can only say this: try getting your data off that device just in case. There's a good chance the moment you reconnect your phone to the internet your phone will be wiped, but I'd suggest trying to disable Android Device Manager, go online, then re-enable it.

Device soft-bricked after flashing Xposed ;-;
Newbie here! I rooted my phone, (Samsung Galaxy Note 3 SM-N900) and I'm trying to get Xposed working. After flashing Xposed*.zip, my device is just stuck on the "SAMSUNG" screen. Do you guys/gals know any way to install Xposed for my phone?
Any help would be appreciated! :D

Maybe you flashed a version that's incompatible with your phone. Some phones need a specific version of Xposed (be it version or CPU architecture). There's an uninstaller zip available. Just flash that and try another version.

Do you have custom recovery TWRP/CWM? If yes then search for uninstaller on place where you downloaded xposed from, and simply flash it from recovery.

First, try to boot your device in download mode, you can do that by:

Switch off your device completely.
Press and hold Volume Down, Home and Power, all at the same time.
Release all buttons when you see the Warning! screen
Press the Volume Up button to confirm that you want to boot Download Mode

Then, download Kies from here, after you install it, connect your phone to your computer and you should get a message from Kies, ignore it.
On the Kies menu bar, click Tools and then click Firmware Upgrade and Intialisation
Enter the information it requires (Usually, you can find them at the back of your phone) and then Kies will factory reset your phone.
To install Xposed, visit this link.

Np, please make sure you mark the answer as correct so other people can see it too.

How do I know if it's safe to opt out of the Android Beta program without wiping my data?
I recently joined the Android Beta program so I could update my Nexus 5x to the latest public release without having to wait for the staged roll-out.
Now I want to opt back out because I don't want to install a beta version.  When I go to the opt-out page, I see a warning that my user data will be wiped if I'm running a beta version:

Unenroll device
You are about to unenroll this device from the Android
  Beta Program. If your device is running a beta version of Android, it
  will be sent an OTA update that will wipe all data on the device and
  install the latest stable public version of Android.
We strongly recommended that you back up all data before proceeding.
  You will lose all data that you have not backed up.

How do I confirm that I am running a public release?  And am I reading the language correctly that my user data will NOT be wiped, as long as I'm running a public release?

You aren't running a Public Release, or ?  In the first sentence you said you opted in to the Beta and are running "the latest public release"...You would first need to determine what Build you are running by going into Settings - About phone - under Build Number.
From the Android Beta site you linked in your post, under "How do I verify that I'm running a beta version of Android?":
1.  Navigate to Settings > About > Build number. If the build number starts with NP, you are running a beta version of Android N.
2.  Reboot your device. You will see a message informing you that your device is running a beta version of Android.
I would assume that if you are running a current Public Release that you would not have to worry about data loss, but as always, backup any files/docs/photos/music you would like to keep in case that happens before opting out of the Beta Program.
The lastest Public Release for Android 7.0 is NRD90S, and Android 6.0.1 is MTC20K according to what Google has posted here:  Google Nexus Factory Images

:facepalm: ok, I'm just blind, but thanks!

No worries, better to ask and understand.  :)

How to check if application on Google Play would work on other (not own) phone?
Is there a way to (at least approximately) check if an application I have found in Google Play store would work on friend's phone.  I'd rather not suggest an app that would not work on friend's phone.
For example is there a way to check if an application would work on Android 2.3, when my phone has Android 4.1.2?

Nowadays Google Play store has (in the web version) "Additional information" section, with table (actually: divs) containing structured information about an app, with the following 'columns': "Updated", "Size", "Installs", "Current Version", "Requires Android", "Content Rating".
While usually the information I want is in "Requires Android" field (e.g. '4.0.3 and up', '2.2 and up') sometimes it is just 'Varies with device', e.g. SoundHound.

Let him try installing it via Playstore. If it's "incompatible by design" (e.g. requires Android 4.x while he has only 2.3), Playstore would refuse to install it and give the hint "not compatible with your device".
Apart from that (and if the app description doesn't give a clue):

check the comments for hints (take care for their date, compared with the "last updated" timestamp of the app; AppBrain lists the history of an app nicely on its "Changelog" tab)
Install the SDK on your computer, and add the corresponding AVDs to it to test out for yourself
Ask for the specific app on a forum, whether anyone can confirm it's running on Android X.X.X / the specific device / ...
Ask the dev (and if doing so, suggest to include such hints with the desc)

I see that some (all?) apps in Google Play have "Additional information" table with "Requires Android" column... though it is sometimes 'Varies with device'

Exactly that's the problem: You can't conclude anything from "varies". And sometimes everything "varies": Android version, size... I wonder whether permissions also vary then. So though you might look there, you not always can rely on that.

Samsung Galaxy S III mini - Cannot turn Bluetooth on
I have new Samsung Galaxy S III mini (GT-I8190N) with Android 4.1.2, and I cannot turn on Bluetooth.
When trying to do it from Settings menu, switch toggles from "O" to "I" position, but remains gray rather than green, list of available devices is empty and 'Scan' button is inative, and when going back to Settings menu I see Bluetooth turned off.

Have you tried restarting the phone?

You can try to reboot / remove battery. Maybe resetting to factory settings will help. In addition, if everything else fails, you could try following (read somewhere about it):  turn it off and then back on (the one asking you about using wifi to localize you faster) the bluetooth and wifi are both 802.11 standards, therefore they are controlled by the same chip

Rebooting phone solved the original issue with Bluetooth, and new issue with Wi-Fi not turning on which made me do reboot.

How to manage browser favorites with Chrome?
How can I manage the position of my favorite links in the grid of chrome?
I have several favorite in the default grid, but the position is determined by the order of saving. I would like to order my favourites by needed (by use for e.g.).
I use chrome with no extensions on Nexus 4 with Kitkat 4.4.3

I couldn't test this approach because my Chrome for Android didn't sync with Chromium on PC. However, the approach theoretically should work.

Make sure Chrome browser both on Android and on PC is synced to same same account. See Why sign in to Chrome.
When the bookmarks get synced, launch Chrome on PC and type chrome://bookmarks in the URL bar. It will open Bookmarks Manager.
In the left pane, choose Mobile Bookmarks.
Hold a bookmark entry and drag it to your desired position.
Wait for the sync to take place and see whether the changes are reflected in the Chrome for Android.

If yes, do tell me!

This approach requires a rooted device. Bookmarks are saved in the file /data/data/com.android.chrome/app_chrome/Default/Bookmarks and the backup in Bookmarks.bak.
Simply pull that file into PC or edit it in Android. Before attempting to edit make sure that Chrome is not running. Force-stop it using Settings  → Applications → All apps → Chrome → Force Stop.

This is a typical look of a Bookmarks file having two bookmarks.

"children": [ {
   "date_added": "13086476457495966",
   "id": "9",
   "name": "Stack Overflow",
   "type": "url",
   "url": "http://stackoverflow.com/"
}, {
   "date_added": "13086471687779090",
   "id": "6",
   "name": "Index of /sdcard/Movies/",
   "type": "url",
   "url": "file:///sdcard/Movies/"
} ],
"date_added": "13086470816073516",
"date_modified": "13086477795302443",
"id": "3",
"name": "Mobile bookmarks",
"type": "folder"

In order to change the position of a bookmark with the other, interchange the following lines of the bookmarks:

"date_added": "13086471687779090",
"id": "6",
"name": "Index of /sdcard/Movies/",
"type": "url",
"url": "file:///sdcard/Movies/"

Save the file and remove the Bookmarks.bak.
Launch Chrome, go to Bookmarks and the changes would be reflected.

Force to buy app with old version of Android
I have two smartphones:

HTC Desire (unrooted / android 2.2 / normal-sim / operator1 / my account)
Nexus 4 (android 4.4.4 / micro-sim / operator2 / my account)

Both smartphone are regurarly  logged with the same account.
I need to buy some apps with normal-sim from operator1 but those app are available only for android 4.0 and newest.
I will use the apps on my Nexus 4 but I do not want to root any device by now.
How can I solve it?

I am not sure how the offers you have work, but could you go to the play store in a browser and buy them there on your HTC and tell it to install them on the N4? I've had to do that for devices since you cannot access the Devices page from the app itself. If necessary, you may have to clear defaults with the browser and Play Store so that you have the option of viewing it in a browser instead of being taken directly to the app. I haven't used 2.2 in almost 4 years, but I assume that that is possible.

I assume that rooting and flashing a ICS rom on your HTC desire is out of the question, so how about you take the SIM card from your HTC to your nexus 4, complete the offer, then switch back? If the offer is tied to the operator the nexus 4 should be able to make the purchase just fine.
If the offer is tied to the device model (HTC), then try this app on your nexus 4 (requires root!). It will make the play store see your nexus 4 as a HTC device. Combined with switching SIM it should satisfy both operator and device requirement for the offer. I'm not sure if it will work for your particular case though.

The sim format are different (micro sim in N4 and standard sim on HTC) and I do not want to put another sim on my N4...

You can always cut your sim to the smaller standard and use an adapter when you need to use it on your older phone. Any phone shop can do this for cheap.
Also, you can flash an ICS rom on your HTC, but it's an arduous process.
The question is, is the offer really worth the trouble? :)

EDIT after reading your comments:
AFAIK, It's not possible.

It is the opposite: I want to buy with HTC desire (android 2.2) and use the app with nexus 4 (android 4.4)

@Ale Edited. :)

The apps are not available for Android 2.2, so I can't buy the apps on Play Store from HTC Desire

@Ale both smartphone are logged with my account What happens when you try buying from Nexus??

With Nexus I can buy it normally (but I have to pay with credit card, while with HTC Desire I can pay with operator offers...)

Oh! I'm sorry. I don't know :(

How to choose the correct email address in gmail app?
If I have two different email address from the same contact like:

firstname.lastname@private.com
firstname.lastname@job.com

When I need to send a new e-mail I am not able to choose the right one because it displays only the first part of the email address.
So I can only view "firstname" and the first part of the lastname...
It happened very often with my contacts with the original Gmail app.
How can I solve it?

Does turning the phone in landscape mode show longer address?

Yes it does, but it is longer (only few instants, but if I could solve it I will be happy)

It looks like you can type a few letters of domain name that you want after a space to get other addresses filtered out. In general, you can type several parts of a email address separating them by spaces to find only contacts that contain all specified parts.
For example, if you have the following email addresses in your contacts:
john.doe@home.com
john.doe@work.com
john.smith@home.com
john.smith@work.com

Than you can type something like john.d w or j doe w or even j d w to get only the first one in the auto completion popup.

At the top of your email you will have star, reply, forward and the 3 dots. Underneath that you will have from who, then the time, and to:. On the same line where is shows (to:) there is arrow pointing down, click on that and it will expand and show from and reply-to full address. Should have no problem seeing ending of addresses now.
Good luck!

I am not able to view the "arrow pointing down" (I use standard GMail app)

@Ale that is on Gmail

@Ale the arrow looks like this (>), only pointing downward. I have the Gmail app installed.

in the attacched image you can see I have no arrow in the field. It do not appear if I start to write a name

I think HasH_BrowN is referring to a received email whereas Ale is asking about how to see the full email address when creating a new email.

@bmdixon went back and saw the picture again,  and your right.  There still should be some drop down when Ale types so as to see contacts with that name, when in landscape the whole email address should show

as soon as you type into the TO text field any saved contact with the letters/symbols/numbers typed will show up in a drop down menu. If they aren't saved they will not show. Also if the theme/color of background/color of font is matching the drop down you will not see whats there. But as to not seeing the endings of the email address, that doesn't make any sense.

@Ale  spent a couple of hours researching on this, the best i could find for this question is this: https://productforums.google.com/forum/m/#!topic/gmail/tNbT7V0zLXs. Basically what this says is that your email information for your contacts are in the wrong fields. See if this will solve your problem, if it does I will edit my answer to reflect it.

How to set personal interval to check data usage?
On my Nexus 4 with stock Lollipop, I can check the usage data month by month, but my subscription is every 30 days (around the 15th).
New contracts last 28 days, so there is more difference between real interval and a month.
Is it possible to set a personal interval (the start and the during) to check it?

As far as I remember, even there is no setting to change the interval since JellyBean, and I'm afraid it's impossible to do it on stock ROM. Most possible, you have to use 3rd-party apps.

Unfortunately I don't have enough reputation in this sub-stackexchange, so I will answer instead of commenting.
This options is not available in Android (up to this date), but there is an issue (which you can star*), which has unfortunately been marked obsolete with no reason whatsoever. Maybe it can be rediscovered if enough people star it.
P.s.: Here is a similar issue which has not been marked obsolete (yet).
Edit: Another trick (which does not really give you the desired effect) might be to use an app from your provider (these often show you how much data you have left).
*Makes it more likely that it might be implemented at some point.

There appears to be another listing of the same issue (with a few more stars).

Go to data usage in setting, and click the drop-down that says some interval (5 Dec-4 Nov etc) and choose "Change cycle..." to change the start date.

It works for the starting day, but I am not able to set the during (30 days is not a month, but there are also week subscriptions)

I disagree with -1 vote because it reply to a part of the question

I found the "Change cycle" option today.
It's at the bottom of the drop-down
I had to scroll past every month from 2014 to 1970 (~520 months)

I am not able to find this setting

It's the same as saloalv's answer actually.

Andrew T, it's not the same answer

Ale, I had to scroll past 1970

Johgru, if it isn't the same answer as saloalv's, please add some additional information.

Can you please add the screenshot? Maybe it helps me to understand how to find this setting

@StephenSchrauger Better?

@Ale I have added a screenshot and some more info

@johgru this setting let me to modify the starting day, not the duration of the interval

@Ale I'm sorry! I missunderstood your question

How can I display my maps (from maps.google.com) on Android smartphone?
How can I access to "my maps" saved from desktop website (maps.google.com) from my mobile device?
When I use maps application on my device I am not able to find my saved maps with my POI and my settings
I am using Android 4.4 on Nexus 4

Google finally offers the solutions:
Google Maps Engine can solve the problem and is free available in the Play Store

However the integration has been lost.

I have to check but it seems that it has only changed the name

Yes the name has recently changed but I meant something different: the integration in a single Maps application has been lost.

Have you explored the layers option in your Maps app? Your saved maps can be shown as a layer.
In the following image (courtsey: HowTo.Cnet.com) you can see the "My maps" section. Expanding My Maps will show all your saved maps. It requires a data connection to use this feature.

Update:
While composing this reply, I cross checked my input with the Google Maps app in my mobile. My mobile is running v2.3.3 and having Google Maps of version 6.x. I could see the "My maps" section in the layer and I could overlay one of my saved maps.
When I saw OP's comment that "My maps" was not found, I cross checked it with my Nexus 7 running 4.3.3 and Google Maps v7.3.3. It has indeed no "My maps" at all. After some search, I understood from this page that "My Maps" has been removed - may be in favour of Google Maps for Business.
Update:
I just found a new app from Google at its Play store named "Google maps engine" which seems to overlay the stored (though not the old ones, but only the ones that were created with new Google maps for desktop) maps.

When I start maps I can only have to dark image you have posted here, I am not able to find Layers as in your left image (I use maps v 7.2.0)

What version are you using to have those capture screen?

I didn't capture the screen, as I said I took it from how.to.cnet.com. my phone has maps of version 6.x and there was no further update. Once went home, I noticed my nexus 7having maps 7.3 doesn't have my maps. However, I was able to see my previous searches and places, but no saved maps. After searching in internet, I saw this page, which says this feature is removed.

This feature was removed :(

I downloaded Maps Version 9.7.1 from the Play Store today, and am now able to view My Maps within the regular Maps app.
Note that I had to actively install the newest version of Maps via the Play Store, it did not update automatically.

Look at the millions of complaints on Google forums: https://productforums.google.com/forum/#!searchin/maps/my$20maps$20android$20app$20
(It's actually a pity there are so many of them, if people searched before posting there would be fewer and stronger threads)
Looks like version 7 removed not just one useful feature:
https://productforums.google.com/forum/#!topic/maps/kRm9Tfvmp2k%5B1-25-false%5D

Google finally integrated My Maps with the regular Android Google Maps app. Click on the menu in Google Maps app, then Your Places, and you will see your My Maps listed near the bottom after Saved Places.

Not available in iOS Google Maps as of yet.

Yes, you can achieve the desired result bu removing your SIM card and connecting your phone to WiFi.

Color saturation cm 13
I have the nvidia shield k1 tablet. It's running cyanogenmod 13 nightly release. On the stock os there was options for color management. Is there any options for this on cm 13?

You can manage color temperature under Settings - Display - LiveDisplay. Other than that there's no built-in option.

If the kernel supports it, some kernel management apps can also fine-tune color, although that's not universal across devices.
