internal memory
My phones internal memory is only 2GB. I only have very few apps like facebook, viber, etc.
When I bought my phone I installed a lot of apps and games but did not have any problems with the internal memory. All of my apps, photos, musicc etc are saved in the SD card. How come I now have a very low memory left internally when I have a lot less apps and games compared to before?

Bigger apps? Storing more data? When I look back a few years, an app of 1 MB size was considered big. Today it sometimes seems that's the minimum size you can get.

Various crash logs tend to clog up internal memory on older devices.  You can try clearing them out by doing the following:

In Dialer app dial the following: *#9900#  Note that this may not work on all devices (specifically on tablets, since they don't have a dialer to begin with.)  Some devices require you to tap the "call" button, while on others the code should start running the moment you hit the last "#" sign.
This will open up the SysDump utility as shown here:

Tap the "Delete dumpstate/logcat" button, and exit out of the app.

This should hopefully free up some internal storage space.

Here is a rundown of steps that can help remedy your problem:

Open up downloads from app drawer, delete all incomplete downloads.
Use a file browser and move all music, movies, videos, photos, and documents to ext SD card.
Open up settings/app manager/all, scroll to Media Storage. Force stop first, then clear data.°
Use a cleaning app such as CCLEANER OR CM SECURITY; to remove old, useless left over data.
Perform a factory reset, backup essential data first.
Go into recovery wipe cache and dalvik-cache, reboot.
Install custom recovery and custom ROM for your device.

° This will not erase any existing files, this will force the system to rescan your device. Any entries for non-existing (left over) files will be removed

First off, be careful in what you mean by "memory" here. You've got RAM that's used by running and cached but inactive apps, and you've got internal storage. I'll assume you're talking about internal storage here.
Apps don't necessarily get stored to the SD card (or "external storage" under KitKat). Some apps cannot be stored there. All apps keep a portion of themselves in internal storage. Apps also store data, including their own caches, in internal storage. Then there are the ad add-ons that may be consuming more space than in the past.
Start first by clearing app caches. Since you're running low on internal storage, I suggest doing this by hand. You may also find some apps you didn't realize you had. As you go through each one, also see if you can move any of them to the SD card. Don't go crazy over this, because some of them won't be worth the time, but it could help.
If all else fails, it might be time for a factory reset and reload of everything.

Battery Drain from mysterious wake locks
I have an huge battery drain issue on my OnePlus One running Android 4.4.2 on stock ROM CM11s O5Q with FrancoKernel R35. I googled and searched so many times but couldn't find anything and I am really desperated now. And hope you guys can help me out.
So, some time ago I noticed that my battery drains over night in "Deep Sleep" 2-8% per hour which is really unusual. I installed "BetterBatteryStats" to look up whats going on, noticing that strange wakelocks are draining my phones battery. Here are to wakelocks event0-875 and event2-875 (see screenshot, this screenshot was taken after charging so dont wonder the -0,5%) which iI dont know and I also dont know to what they belong to.
I read so far that event0 are androidOS stuff wakelocks and at the end of a day I have round about 30-40% left mainly drained buy AndroidOS, as I can see from the built-in Bettery Stats. We have to see that its a 3100mAh battery and i usually dont use my phone at all during the day.
I already greenified some apps to see if its an app which is causing the drain but no success so far.
Today in the evening I cant post you another screenshot from WakelockDetector app. The statistics resets after charging the phone.
I hope you guys can help me, thanks so far!

BetterBatteryStats (click image to enlarge)

does rebooting/restart the phonef fix it temperary?

No I tried it several times inlcuding clearing cache and stuff at the end of a day the same result showed up

what if no internet access ( OS update )?

I dont understand the question :) I am usually all day connected to WLAN. The phone turns WLAN of if not necessary and in sleep i guess

check 'data usage'. can you see 'android OS' in the list.

I see Android System with 8.5MB

possible OS update. Can you try this : recharge to 100%, switch to flight mode , restart phone. watch for some hours/day.

If you're rooted, try Greenify. It will hibernate all the unused apps and thereby releasing resources which sucks up your battery juice.

Centrally managing large number of android tablets
I'm involved in a project that will deploy approximately 400 android tablets. All the devices are on the same network. Is there an easy way to centrally manage the following:
Creating and updating policies to restrict users from launching apps or updates
Update a custom written application
Set device into kiosk mode and auto start an app
Any help would be appreciated.

I've just put the correct tag on your question. You might wish to check other questions using the same. Probably relevant as well is the tag remote-control. Related question: centrally manage corporate android devices (and the ones linked to it).

VNC server + shell script or try some thing like air_droid etc
Install in each tablet
enjoy :)

Welcome to [android.se]! Could you expand this answer, like example of how to use shell script, and why and how Airdroid could help this problem? On Stack Exchange, answers are not only for the asker, but also for future readers. Not all people know how to use them (well, I don't). Thank you.

If you have the resources to write the policy code yourself, to achieve this, Android has an API for affiliation to become device administrator.
If you want an out of the box solution, there are a number of applications on the Play Store that does this. You should evaluate the balances between cost, ease of use, and required functionalities.

my internal memory is empty but cant add new apps
Not enough storage when loading apps to my phone why is this and my internal memory is empty, also new 4gb memory card is brand new.

I've just added the insufficient-memory tag to your question; please see its tag-wiki for some background and first-aid. Trouble in such cases is not storage per se, but device internal storage. If that's down, no matter how much free space you've got on your internal/external SD card, you'll get this error.

I think that this has already been answered in this thread
You may have sufficient internal strage space, but not enough space on the /data partition.

Open settings>storage>miscellaneous and delete all the files from here
Also delete cached data(by touching it)It happened with me too but now every thing is fine I found a file named 0 in miscellaneous and on deleting it my phone started working properly

How to downgrade from Lollipop to Kitkat?
I am using Spice AndroidOne. When I purchased it, there was Kitkat in it. It automatically requested for Lollipop update which I have granted. Later it has requested for Marshmallow update. When I tried to update it, it has given an error.
Now Android OS is eating all my data (3G) in one day without my permission.
How to rectify it. And also I want to go back to Kitkat version.
Kindly help me.

Have you done any research for downgrading at all? Because the first thing that shows up at Google is this video that shows you how to do that

Your question is way too broad. Either decide to rectify data consumption issue or to downgrade to KitKat. For whichever case you choose to,  tell what have you attempted so far?  Furthermore, give us the screenshots of Settings -> Data usage -> 3G as well as Wi-Fi, only for the data consumption issue.

Unfortunately you cannot downgrade from the newest version of Android to an older version, unless you root or modify your device's permissions. Ask your carrier to see if they can flash a new ROM to your device.

What "permissions" of the device need to be modified for that? First time I hear this. Usually you just have to find a matching ROM (see Where can I find stock or custom ROMs for my Android device?) and flash that – downgrade, upgrade, or just "something different" should not matter.

this is not true at all ,this is an android device with unlocked boot-loader and have no security to avoid downgrades ,an older rom can flashed using the SP Flash tool like any other mtk device without root and without editing "permissions"

How to remove Taboola adware?
I have factory-reset my mobile, and had already scanned with antivirus for adware, which it found but it couldn't remove. What should I do?

If a factory-reset wasn't able to cure it, it sits in the system. The only trustable way then is to flash a clean ROM, sorry.

While it's not really the same adware, consider this question about wonderlandsads that has same SpyHunter reference when searching for this adware.

The only method that is left if it the adware truly resides in your phone memory is to flash your phone with its original ROM.
You can also try full resetting it after removing your memory card, sometimes adware comes from the files which were saved on memory card.
Try out a full wipe, don't worry, you can get out of this problem.

How to play multiple files on multiple Androids?
I have three Android devices and I have three tracks: a bass track, a drum track and a vocals track.
What I want is to play each track on each device simultaneously, like, one Android plays the drum track, the second Android plays the bass track and the third Android plays the vocals track, all of them simultaneously.
I can also use a Windows PC to stream or remote control the devices.
I've used many apps like AirFoil or SoundWire, but I can only play one track at the time.
Is there a way to achieve this?

Maybe a batch file with a few adb commands will do the trick. Unfortunately I do not know the commands for opening a sound file on a phone (and properly syncing them as well).

Have the tracks loaded in the device. Then use a music player in each of the device, load a particular song (it would start playing) and reset the song progress to beginning. When you're done doing this in all of your devices,  (as GiantTree noted) dispatch (for Android 4.4 or above) adb shell media dispatch play for all the devices. They would start playing the song. Alternatively, for other Android versions, find the music player's activity responsible for playing the song and pass the data (the song file) into them using adb shell am start.

Another thing you can do is make [tag:Tasker] or an other competent app to play the files at a particular time in the devices.  Have the devices synchronize their time setting with a global time server for better synchronization.

YU Yureka freezes and reboots since the last Lollipop upgrade 5.1.1
I have YU Yureka. I upgraded it to Lollipop 5.1.1 last week.
Since then, the screen goes blank most of the time whenever I open any application and then it comes back in few seconds and phone restarts automatically many times.
Please can you help me out about this issue?

If this happens after an update you should do a factory reset from the recovery menu and clean your partition cache. Some malfunctions like this is expected in most of the devices after a system upgrade or firmware upgrade. It is always good to clean partition cache after every firmware update.
If you don't know how to perform a factory reset from the recovery menu and to clean partition cache just google it. You should back up all the needed data before factory reset because it will erase everything in your device.

How much (Idle) time is needed for "Doze" to get activated ? (Android 6- Marshmallow)
Consider a device that was left on a table, unplugged, and no movement. After sometime, the screen turns off, and the screen lock may (or may not) be auto activated, according to lock and smart lock settings.

Firstly, let's assume its locked, how much time is required for Doze, working to save power?
On the other hand, if the smart lock is acting (like by geographic location), keeping device unlocked for several hours (is six the limit, right?), how will this affect "Doze" functionality?

First part of your question "Firstly, let's assume its locked, how much time is required for Doze, working to save power?"

Idle time is not specified by Google and I guess this is implemented differently by OEMs
Quoting from Google documentation  Optimising for Doze and stand by  (emphasis added)

If a user leaves a device unplugged and stationary for a period of time, with the screen off, the device enters Doze mode. In Doze mode, the system attempts to conserve battery by restricting apps' access to network and CPU-intensive services. It also prevents apps from accessing the network and defers their jobs, syncs, and standard alarms.
Periodically, the system exits Doze for a brief time to let apps complete their deferred activities. During this maintenance window, the system runs all pending syncs, jobs, and alarms, and lets apps access the network.

Edit : This may answer from a user perspective as this is what developers are apparently planning 9 minute interval
Source https://plus.google.com/+AndroidDevelopers/posts/94jCkmG4jff

Dianne Hackborn17 Nov 2015
+Petr Nalevka Sorry scheduling alarms so frequently is currently not supported in doze....For what it's worth, the minimum time between while idle alarms will be changing to 9 minutes at some point relatively soon (even on devices running the current Marshmallow builds).

Second part of your question ".... if the smart lock is acting (like by geographic location), keeping device unlocked for several hours (is six the limit, right?), how will this affect "Doze" functionality? (and a related question of yours How Doze (marshmallow feature) work during playback?)

It is difficult to answer this correctly as

As can be seen from the answer to first part of question, developers seem to be improving / modifying the behaviour of "Doze" functionality and only once it is matured and implemented, one can reach a conclusion.

As can be seen in this post https://stackoverflow.com/questions/33018306/doze-mode-and-foreground-service, thanks to Firelord for highlighting this
, documentation by Google is lacking in details and developers/ OEM may implement varying behaviors, so nothing can be said at this point of time with certainty.

How can I make sure Bluetooth is working every morning?
I use Google Clock & Spotify as my morning alarm, with OnePlus 11 connected to my Marantz NR1200 stereo receiver.
When this works, the alarm sounds and plays. It has worked about 4 out of 5 times. But, because there is a sound delay of about 1 second between the phone speaker and the main speakers, I usually set the alarm volume on the phone very low, and to get a sufficient volume on the main speakers, I have to set the media volume on my phone at around max. The volume on my Marantz is also tied to my phone media volume, so it's set at 72.
This is kind of scary though, as sometimes if I accidentally play music from the phone or have any other media sound, this plays extremely loud on my main speakers. The alarm sound is okay, I guess because the low alarm volume and high media volume balances this out.
So, every night, I have to make sure the media volume is max, the alarm volume is low, and silent mode on the phone is activated (so as to not be shocked awake by a notification)... so, not optimal.
The real problem is when Bluetooth doesn't sound at all. It has happened about 3 times since I got the Marantz. When it happens, the alarm plays from the phone at a low volume, but nothing from the main speakers. The phone is connected via BT to the Marantz as shown in the display of the receiver, and also in the BT menu of the phone.
This makes my morning filled with some anxiety, because I am so used to waking up to music and I need this to keep working, or I might have to change receiver.
I have considered putting in the old solution from my previous receiver; a phono cable in the back of Marantz to a minijack on my phone; but having tried that the sound was awful in comparison, and because of the high volume, I could hear the speakers static constantly.
So I was hoping anyone could help me remedy this situation. I don't have enough know-how to even begin to troubleshoot this.
Any helpers?

Do you have other BT devices?

No, just the receiver and my phone

Leave it alone, is the advice on other forums.

That's a Samsung specific system app. You can't remove or disable it from the UI. Please consult Samsung for more information about it.

From google.support.

This is a pre-installed app, idk why someone said the customer support said it didn't, there is a company called MMI group and I think the app is some kind of test or something but it is pretty sketchy but malwarebytes is fine with it

How do I physically remove the radio chips on a phone?
I recently dived down into the world of privacy and looked at how many privacy advocates would physically remove the microphones and cameras on their phones by desoldering them.
However, when I researched how to remove the radios (e.g. Bluetooth, WiFi, GPS, and the standard cell radio that connects to cell towers), I came up with nothing. I couldn't even find much on what they looked like or where they were even located on the phone's board.
So my question really is, where are these chips on the board and what do they look like? And can I even remove them at all?

Usually smartphones use a "System on Chip" (SoC) which means everything is integrated into one chip. So removal is next to impossible. Even if there would be a second chip, the chance would be high that the phone stops working if the chip is removed. You should better buy a tablet and keep it on AirPlane mode.

Just install a decent antivirus program. And keep passwords complex and  secure.

There is also the PinePhone or PinePhone Pro (although not really Android devices) that have physical switches to turn on/off various radios in the device including the cellular radio, WiFi, GPS, etc.

@acejavelin I double checked and the pine phone does have dipswitches to turn off the wifi, gps, bluetooth, cameras, microphones, headphone jack and modem. By switching off the modem, does that mean the phones cell radio is turned off and will not be able to connect to a cell tower at all?

Yes, that is correct, turning off the "modem" switch powers off the cellular modem and it will no longer have any connectivity to the cellular network. That said, realize this is a Linux hobbyist device... not a "polished" Android device like from a regular Android device manufacturer, it isn't exactly a daily driver for most people.

Can't unlock Pixel 6's bootloader
I have no problems finding my Pixel 6 through adb. Also, no problems finding the device with fastboot devices while in fastbootd. But for some reason, when I switch to bootloader, the computer doesn't see the device.
Windows's USBView shows me absolutely nothing connected to the corresponding USB port. Tried on macOS as well, same thing, through 'system report' I see that literally nothing is connected to the port.
I have the latest platform tools on both PC and Mac, latest Google USB driver (on PC). USB debugging and OEM unlocking are enabled. Tried with a couple of different USB cables, in every possible port. Also, tried disabling driver signature enforcement on Windows 10 and had no luck.
I don't know what to do anymore, I read everything there is on the internet and all they say is to update drivers/change cables, etc. Any help will be greatly appreciated.

What do you mean by "when i switch to bootloader"? Usually fastbot and bootloader mode are the same.

newer androids have a new fastbootd menu(with 'd' at the end), which is different from the bootloader, you cant flash or unlock bootloader from fastbootd menu for example

what do you mean dont need to use fastboot? is regular fastboot the bootloader?
Will try downgrading platform tools, okay, thanks

doesnt seem to work with older versions aswell... tried 30 and 31.
same thing

Maybe it's one of those devices whose boot loader can't be unlocked for example

If it's not carrier-branded , you can try Pixel flasher in advanced mode // I have not used that mode at all , so read well beforehand

Correction to my earlier comment. I didn't use fastbootd, normal fastboot was enough

I bought a compatible cable and all worked like magic.
Obviously bootloader is very pretentious

It all worked like magic after buying a compatible USB cable.
4 days wasted for a damn cable...
A compatible USB cable in this case was a samsung one.
We tried like 6 or 7 different ones until we found the device while in bootloader with it.

While we're glad that you found a solution by yourself, could you [edit] and expand the answer? To help readers who may face the same problem, what does it mean by "compatible USB cable" in this case?

How to Root Xolo One

Hardware  : MT6582
Model : XOLO One
Build number : XOLO_One_S006_14012015
Build date UTC : 20150115-031031

Kernel version : 3.10.54 (jenkins@80-32) (gcc version 4.8 (GCC) ) #1 SMP  Thu Jan 15 11:22:17 CST 2015

Description:- I tried everything (Framaroot, kingoroot, iroot) but no progress, can't root it at all. I am not an expert.Is there anyway out ?
When I bought the phone it was running on Kitkat and was rootable because one of my friend did it. But after updating to Android 5.0 it seems there is no way out.
Few things that I found while trying to root it :-
-File /system/recovery-from-boot.p which restore factory recovery in case of phone switching on in a normal mode Is Found.

You can root XOLO phones using Framaroot application. The framaroot application helps to install the Superuser and su binary on the android phones (but compatible only for few android devices).
Before Proceeding:
1.Take a full backup of your phone by using appropriate backup applications.
2.Once you have backup your important data’s which was available in your phone, check the battery level of your phone.
3.Incase, if it is low charge them fully, so then it never get switched off during the middle of the rooting process.
1.First, download the framaroot.apk from this page of xda-developers.
2.Once you have download this application install the same in your device.
3.After that select the SuperSu from the dropdown menu.
4.Select the Boromir now and reboot the phone.
5.That’s it! Now, your phone has root access and you will get success message which implies The SuperSu and Su binary was installed.
6.After seeing this message on your mobile, just reboot your phone.

I Can't Access Google Playstore Nor Gmail On My Huawei Y220
My Huawei Running On Android v2.3.6 can't access gmail and google playstore anymore. I deleted the pre installed Emails but everything was working fine until when I once switched the phone off and when I switches it on, anytime I open the gmail app, it shows a blank white page which doesnt last for a second. when I open playstore, they tell me to add a gmail account but when I try adding, I am sent back to the home screen. it is rooted. ia there anything I can do to make it function like before?

It might help to [edit] your question and include exactly what and how you deleted. Looks very much like you deleted too much while using your "root powers".

I deleted the maps and emails but NOT Gmail. I did it with titanium backup

Which files exactly did you delete? Hint: Next time, better try freezing apps first to check for potential side-effects before deleting files. And when deleting files, keep a backup somewhere so you'd be able to put them back if needed :)

All right, thanks. I Reinstalled Google Play Services And It Came Back To Normal. Thanks For Yo Comments, I Really Appreciate It ;)

Glad you've solved it! May I ask you to make that an answer, including some more details, and then accept it? That would then help others in similar situations to identify this problem here has a solution. Thanks a lot!

Smashed screen on Xperia Z3, need to download data without touch capabilities
My wife accidentally smashed the screen on her Sony Xperia Z3 and the touch screen is not useable. There are colors and lines but nothing else. All of the ports on the device work just fine. However, I cannot access the phone's files with my PC because USB connection settings are currently set to charge the phone. I need to do the Data Transfer setting but am unable because of the broken touch screen. I talked to Sony support and they were no help whatsoever.
Can someone please tell me if there is a workaround? I am a tech so I will understand what you are saying even if it is complicated.
Thanks,
Mark

Also take a look at our data-recovery tag-wiki for additional details.

I have a phone with smashed screen as well and need to recover photos and videos. Searching around I have found several places where they mention using OTG (On The Go) USB cable to hook up a mouse and keyboard, also you can possibly hook up the phone to HDTV as explained here:
http://androidforums.com/threads/broken-screen-no-backup-and-need-your-data-try-this.841614/
I am yet to try the methods described as I need to buy the necessary cables first.

I have an otg cable and mouse and yes it will work although it will take some time to get used you should know that when you want to move you have to click and drag but other than that just a mouse should work fine

I have the task of setting up 50+ tablets (Binatone Homesurf 744, Yes cheap & cheerful!), which all need the same App installed and same wireless settings entered but require different configuration files (config files stored on SD card).
I was hoping there might be a solution which I can set up each of the tablets via ADB or a script without root access if possible (as this would an additional step and take more time). The tablets so far have come out the box with debugging mode already enabled. If I access the tablet via ADB and type "su", it does give me some kind of root access as the symbol changes from "$" to "#" but I'm unable to remount the /system a rw.
The process I would like to do is as follows:-

Start Tablet and plug in via USB cable to the PC for ADB access
Automatically Disable/Skip "Welcome" screen (Initial Setup Wizard)
Install Wireless Settings
Install Required APK
Push Required Configuration Files
Restart Tablet if Required

I think I may have answered the question about disabling\skipping the "welcome" screen after a bit of research. This I believe requires full root or rw access to modify system files (ro.setupwizard.mode=DISABLED, I believe?).
With regard to the wireless settings, I'm able to add the wireless settings manually in ADB shell via the following command after switching to the "wifi" user (issuing "su wifi"):-
echo 'network={\nssid="Wireless"\npsk="i*********m"\nkey_mgmt=WPA-PSK\npriority=1\n}' >> /data/misc/wifi/wpa_supplicant.conf

After restarting the wireless via ADB, the tablet happily connects to the newly added wireless.
I can install the required APK and "push" the required configuration files manually or via a batch script on windows.
Any help would be appreciated on automating this and making things as simple as possible.
Thanks in advance!

If that ADB command works, the tablet is most likely rooted – as files in /data/misc are usually not writable by anone but a system user. I don't think there's a way to automatically skip the wizard (and no app can plug in the cable for you), but everything else should be easily possible. One thing I need to know before being able to answer: What OS is running on your computer? I can setup an answer for Linux, if that's acceptable (which should also work on a Mac, and could be adapted to Windows).

Thanks Izzy, I have access to both Linux and Windows so an answer for Linux would be greatly appreciated at least to give me an idea of where to start.

OK, so here you go! I've included some explanations which should make it possible to adapt the idea for other systems as well. Hope you'll find it helpful!

So here's a solution for Linux. The first part you already mentioned in your question, but for completeness I'll include it nevertheless:
#!/bin/bash
#
echo "Plug in the cable now, please!"
# Just kidding: That and skipping the intro you'll have to do manually :)
# As well as ensuring that USB debugging is enabled etc. Test with
# "adb devices". If it shows the connected device, go on.

# Install Wireless Settings
echo "Installing wireless settings..."
adb shell su -c "echo 'network={\nssid="Wireless"\npsk="i*********m"\nkey_mgmt=WPA-PSK\npriority=1\n}' >> /data/misc/wifi/wpa_supplicant.conf"

# Install Required APK
# assuming all the required APK files reside in a "install" sub-directory:
echo "Installing APKs..."
for apk in install/*.apk; do
   adb install "${apk}"
done

# Push Required Configuration Files
# these and all other files you want to push you've placed into
# the "upload" sub-directory **WITH FULL PATH** (e.g. to push "foo" to
# "/data/local", it would be saved as "upload/data/local/foo
echo "Uploading files..."
adb push upload /

# Restart Tablet if Required
echo "Rebooting device..."
adb reboot

Of course, this is just a skeleton; you might wish to have some "success checking" in place, or write a log to evaluate later. But it contains all the technical stuff you need:

adb shell su -c "command" to execute a command as root – here for appending your wireless settings
adb install to install your APK files. In case these are just newer versions of apps already installed on the devices, add the -r (re-install) switch; a simple install would fail then (i.e. make it adb install -r "${apk}")
adb push to transfer files to the device. Note a few things here:

Syntax is adb push <source> <target> (the counterpart would be adb pull <source> <target>)
you can push a file, or an entire directory
<source> and <target> must be of the same type (i.e. either both are a file name, or both are a directory name)
you can only push to directories you've got write access to. So in order to push into "system areas", the ADB daemon on the device must be running in root mode

As the last condition usually is a culprit (on "production devices", adbd runs in "secure mode" – i.e. non-root), use a work around by first pushing the files to a "common area" (e.g. the internal SD card), and then copy them over. Example:
adb shell "mkdir /sdcard/misc"
adb push upload/data/misc /sdcard/misc
adb shell sudo -c "cp -a /sdcard/misc /data/misc

And as a last hint: You might need to check permissions (incl. ownership), at least when it comes to system relevant files. So first try with one device, investigate the results, see if it works as expected (adjust if not – incl. adjusting your script(s)) – and if necessary factory-reset and start over to verify it's working now. And BTW: These "install and upload" stuff is the next item on my ToDo list for Adebar ;)
Good luck!

PS: that "install and upload stuff" is meanwhile implemented in Adebar :)

Stop announcement of who is calling me
How do I stop my phone from announcing the name of who is calling me on my Droid Razr Maxx? I've gone into my settings and can't find out why this is doing this.

See if my answer works. If not, let me know. If it does, you know what to do. :)

You probably have Driving Mode enabled. In my Samsung Galaxy S4, it's in Settings > My device > Driving mode > Incoming call. See if you can find something similar on your phone.

How do I stop all running apps in the Samsung Galaxy S3?
Device: Samsung Galaxy S3
Android: 4.1.1
I need to stop all running apps for an app, but how do I do that with one click? Is it safe?  Does the S3 have a tool?

Question is: What makes you need that? Android takes care pretty well to clean up if ressources are required. Task killing is rather contra-productive. If you'ld add some background, there might be better approaches to your goal -- and your current question might turn out being a XY problem ;)

Long-press the home button.
You should see something similar below.
NOTE: It is from a Samsung Galaxy S4, but S3 should have it also.
Then, click the 3rd icon (lower right).
YES, it is safe. It will close all open apps.

Screenshot (click image for lager variant)
UPDATE #1: Just to clarify Izzy's comment, he's partially right. Clicking the button will not close all running apps, but it will close all apps have you have manually opened. e.g. If you opened 3 different browsers, and clicked the button above, those 3 browsers would close. However, it will not close background processes / services that are running (e.g. AdBlock, aCalendar+, etc)

Sorry to disappoint you, geff: but that will not close all open apps. It will only remove your recently-used apps from the list and kindly ask them to "calm down" (see also Do applications that remain in Recent Apps list take up resources?). Even if the additional button Samsung has placed there does kill the apps, this only handles "recently used", not necessarily "currently running". See Settings->Apps->Running to compare. Please correct me if this general rule is not valid for Samsung devices ;)

@Izzy Added Update#1 so that it's a bit clearer

Yepp, that fits better. Though that list is still named "recent apps" (and in older Android versions was limited to 6 or 9 entries), my experience with ICS/JB matches your description (apps are kept here until the user "swipes them out" explicitly). And that "kill button" (as well as the others visible in your screenshot) seem to be a Samsung extension to merge in a kind of task manager :) // Thanks for your update, geff -- much clearer now!

@Izzy After clearing my list, it says "No recent apps". So yeah, it is still the recent apps list.

Exactly. So to make your answer complete (on-board solutions), you might want to add the Settings->Apps->Running list, where one can walk each entry and "force stop" the corresponding apps/services. But that's even less "one click" then the "recent" list ;)

Try using a task manager or a task killer app like Advanced Task Killer.

If you are rooted your Android then 'Greenify' is your answer !
It will help to hibernate all running services/apps/processes and free up resources.

In what language is Gingerbread OS written?
Are all versions of Android written in the same language or in different languages?

Not Gingerbread-specific, but according to Ohloh, Android was created using:

C
C++
Java
Others

+1 Also ARM Assembler, and Java runs on the Dalvik VM instead of a standard VM because it is compiled to ARM Assembly code before it is put on the device.

Change pattern lock to Thin Pattern Lock like in ICS
Device: Micromax A57
Android: 2.3
How can I change the size of the unlock pattern grid like this:

That is ROM dependent, do not think you can change the grid size as its built in. Solution would be to look for a alternative lock screen, am sure there is plenty on the Play Store.

Try "Go Locker"
https://play.google.com/store/apps/details?id=com.jiubang.goscreenlock
Gives you a wide variety of lock screens to choose from.

Speed of Nova or alternative launchers?
I'm thinking of getting the GS4, but plan to use Nova Launcher. When using an alternate launcher, will this negate any slowness or lagging introduced by TouchWiz?  Or is the damage done deeper in the ROM?

I have a Samsung Galaxy S4, and Nova is surprisingly snappy on it. You can change how fast the animations / transitions are. In my case, I set it to faster than light. If you're not content with that, you can go further and disable animations / delays via the phone's Developer options settings.

YouTube app stops loading
Device: Xperia V
Android: Stock ROM, rooted
When I watch some YouTube video on the YouTube app, it plays up to some point. Then, it just shows that it loads, and never continues. Why is that?

Are you using YouTube app, or stock browser?

I am using the YouTube app

What happens when you access YouTube via your browser? (Assuming you're currently using Wi-Fi) did you try using 3G/4G to access YouTube

And did you try Main Menu > Settings > Applications > Manage Applications > YouTube > Clear Data?

Trying to go into Download mode, but goes to Recovery mode instead
Device: Samsung Galaxy S4
Android: 4.2.2
I can't get into Download mode. I have tried many options like removing battery solution, pressing Vol Down+Home+Power. I always get into Recovery mode.

Power off the phone completely by removing its battery for at least a minute.
Re-insert the battery back into its place.
Press and hold Volume Down, Home and Power buttons, all at the same time.
Release the buttons only when the ‘Warning!!’ message appears.
Next, press Volume Up button to confirm that you wish to enter Download Mode.
Your device will now show a green Android with the ‘Downloading… Do not turn off target’ text listed under it.

That's it, now you can connect your device with your PC after you launch ODIN.
You can try adb reboot bootloader from PC if the above doesn't work.

You can do it the easy way: Download ROM Toolbox. Then choose reboot to download mode.. :) good luck

please note that, not all are familiar with the tools you are mentioning in your answer. you may want to edit your answer and provide ref./link to download rom tool box and brief about how to use it

How do I add other apps to Samsung's multi-window/sliding app in Android 4.1.2?
I just got the Android 4.1.2 update.
I know how to disable the multi-window/sliding app section. I know how to add and remove the preassigned apps there, but how can I add other apps (e.g. camera, calculator, standard music player and other apps I have downloaded and installed)?

You can't add just any app to the multi-window list (the one you get by clicking Edit). That list only contains apps that have been written using Samsung's vendor-specific library to support the multi-window feature. (I suspect that the feature also has special-case code to enable the Google apps in the list such as Hangouts, but that's just speculation on my part.)
You can only make an app appear in that list by contacting the developer of the app and asking them to support it. It may be an up-hill struggle to convince them to invest time and make their app larger to support a feature used by a minority of users on one manufacturer's devices.

yes, I found where to disable it...under settings....display....multi window. but at that location you can only enable and disable, you have to edit the window onthe main page :)
I can understand for sure how the diff vendors may not want to convince them to support it!  thanks for the reply!

Wanam Xposed Method
On a stock Samsung ROM, there is no option to edit the Multi-Window apps, and you can only select from a few apps.
However, you can work around this with an Xposed module called Wanam Xposed which lets you customize which apps are shown in that viewz as well as many other aspects of a stock Samsung ROM. To use this, you will first need root. There are many tutorials about how to root various devices on the XDA Forums. You will then to install the Xposed Installer and then activate the xposed framework and the module. You should then be able to customize many things on a stock Samsung ROM, including the Multi-Window apps.
Note: Please read all warnings pertaining to root, and research about root access before you try modifying your device, as it can lead to unwanted changes in your system. Always use caution when dealing with root or any modification of your device.

By default, you can't add other apps to Samsung's multi-window feature.
However, you can use apps like Samsung Multi Window Manager to work around this limitation. It also has a Pro version that has additional features.

Using this Multi Window Manager, you can enable ANY app to take
  advantage of this awesome new feature.

I like the multi window feature, too bad they don't allow the addition of other apps.
will try the Samsung Multi Window Manager, thanks for the inftormation

@Donald You're welcome. Please don't forget to upvote and accept if you're good any of the answers here. :)

Your phone needs to be rooted to use that app BTW.

How to access and/or delete an invisible Exchange account?
I seem to have somehow developed an invisible exchange account on my rooted (but otherwise stock) 4.1.2 AT&T HTC One. I don't know at what level to attack this problem -- is it a Sense issue or an Android issue? What app or data should I delete / uninstall or clear?
If I go to Settings -> Accounts & sync -> under the "Manage Accounts" area there is no Exchange ActiveSync account even listed.
If I try to add an "Exchange ActiveSync" account I get the Error message in a popup box that says "You have already set up this Exchange account." Googling for that message or searching for it on xda did not yield anything helpful.
I'm not sure if this developed at some point from a Nandroid restore or what...
Does anyone know how to delete this invisible Exchange account that it says I have already set up? I can't see the account anywhere to delete it, but it's data must exist somewhere inside "Accounts & sync" and so it thinks I have already set it up... I'd like to delete it for real and then re-add it.
UPDATE #1: I don't use any Exchange services (Outlook Web, nor MS Outlook).

I think I have encountered a similar issue before. Not sure how I fixed it, but

see if you have a Device Administrator for Exchange. In the Samsung Galaxy S4, it's in Settings > More > Security > Device Administrators. Uncheck / Remove it there, do a restart, and see if that helps.
or:  Go to your application manager, and swipe to the ALL section. Then look for the Email app. Click that and do a Clear data and/or Clear cache. Also, look for the Exchange services app, and do the same. Restart, and see if that helps.

Based on Asker's feedback, the second approach fixed the problem. He also cleared the GMail app, although it's not necessary.

Thanks for the idea... but not a help in this case.  I went into "Device Administrators" on my HTC One, but there are no accounts listed in there.

I'm thinking that the only way to fix this is to do a factory reset and then reinstall all my user apps (being careful not to restore any system settings).  So I will probably have to do that, but if anyone does discover the answer please post.

second bullet point also fixed the problem for me on my LG Optimus F3. Thanks a ton!

The initial suggestion is what I was looking for to delete an account that couldn't be deleted.  On Lollipop, it's the Gmail app that's listed as the device administrator, since the Email app doesn't exist anymore.

Deactivating Device Administrator for email worked for me. Had to pause my Twilight app (brightness app) to confirm action on dialog. Thanks!

Clear cache did not work.  Have to do Clear Data.

Here's how I fixed this on my HTC One
1. Open Settings -> Apps
2. Find the Mail application in the list of all Applications
3. Press the "Clear Data" button
4. Reboot the phone.
After doing this I was able to add my Exchange account

Thanks.  Clear Cache didn't work.

I developed the "Duplicate Account", "You're already using this username..." problem after using AkrutoSync in multiple locations with the same laptop over WiFi. I was using different routers at each location of course, which, provided  different IP address. Seeking a better way to change locations/servers/IP address, I experimented with the server IP address settings and the result was that I locked an exchange account into a file and could not delete the account. (Nexus 5X on Oreo 8.1.0) I cleared data and cache for both my gmail and my Google Inbox app, then rebooted and the problem was solved. Thanks.

Under Android 7.1.1.  I had deleted my work Exchange account because I was trying to troubleshoot why that account wasn't syncing parts of my calendar.  I went to accounts and deleted it, then when I tried to recreate it I got the same dialog, wouldn't let me set it up with the username on my Excahnge account, said it already existed.
I restarted, deleted all my gmail accounts as well to no avail.  Tried wiping the cache in the fastboot menu, same thing.  I finally ended up going to Settings/Apps/gmail, but there is no button to clear data, so I disabled gmail, and it asked me if I wanted to go back to the original installed gmail.  I confirmed that, restarted, and I was finally able to add that Exchange account.  Hopefully sometime soon it will update gmail, but either way it is working.

I had this problem on a Xiaomi Poco X3 just now.  I had removed the 365 exchange email account from gmail client to enable 2 factor authentication then when I added the account back in gmail said it already existed and would not let me.
After trying the above solutions and them not working for me I realised that my google account on the poco x3 used the same email address as my 365 exchange email account.
I removed my google account credentials first then re-added my 365 exchange account in gmail which it accepted this time and then once the emails were working I added back my google account credentials with no problems.
It worked for me.

Go into the Mail App.  Go to Account Settings....  Delete account.  Keep deleting until the exchange account is deleted.  Then re-add the accounts.
Works like a charm!

Recover data from Asus Zenfone 4 in special case
My Asus Zenfone 4 (ZE554KL) started to be slow and sometimes it crashed and restarted, and then it went back to normal. It stayed that way for months. Last week, the bar containing the buttons to access the apps disappeared, and the only thing I could access was the top bar, scrolling down, but I couldn't access anything except the Settings. In the Settings, none of the changes I made worked, and it always ended up crashing and restarting.
At a certain point, I decided to try starting in safe mode, so I pressed the shortcut and it worked. It started normally, but a few moments later it simply restarted, and right after the Asus logo screen, it fell straight to TWRP, on a screen asking for a password to decrypt and mount. I tried every possible password I've ever used on my phone but none worked.
I tried to cancel and go to File Explorer, and there I got a surprise: Internal storage was listed as 0 MB. I tried to connect my cell phone via USB cable to the PC, entering fastboot mode and only the SD card appeared (where I didn't save anything).
To recap the problems are as follows:

My Android does not start, it goes straight to TWRP asking for a password to decrypt and mount the data.

When I click cancel and try to access files through TWRP's file explorer, my phone's internal storage is listed as 0 MB.

When trying to enter fastboot mode through TWRP and connect the phone to the PC, only the SD card appears, where I never saved anything.

I need to save my WhatsApp data that is not saved in the cloud or locally, being just the application data and being all the most important work in my life, WhatsApp remains connected via WhatsApp Web, and I can only access recent messages, and I know that soon it will disconnect because my cell phone does not start Android anymore.

I saved important things on my WhatsApp, and as my cell phone's storage was always full, I never made a local backup, nor on the Google account because I didn't have any account with enough free memory (I had a lot of things saved, they exceeded 15GB). My WhatsApp is still connected through WhatsApp Web but I don't know for how long, and I can only access the most recent messages because the oldest ones can only be accessed through the cell phone.

Based on what you describe the flash memory of your phone could be defect. As your phone is about 6 years old flash memory problems are reasonable.

Yes... something solution?

Sorry but that is difficult to answer. For example it is not clear if your device uses hardware encryption or not thus if it would be possible to decrypt the data only with your password/PIN. If that would be the case you could try to make an image of the user data partition and try to decrypt the data on a Linux PC.

As I mentioned, when plugging in the usb cable, the internal storage does not appear, and TWRP does not appear either, but I believe it is due to the encryption, I believe it is the default encryption of android, I already tried to type my pin but it did not work. My pin has zeros and it was numerical, I saw in other forums that there is a problem with typing zero in twrp, but I didn't understand the reason.
Is there a way to make a nandroid or internal storage backup image? Or at least manage to copy WhatsApp folders to restore conversations on a fresh android installation?

Have you tried TWRP support, they may have suggestions.

Where i find they?

In-app update out of the Play Store?
I have a local Android application,  a custom scanner application, that is used in a cabinet factory production environment.
This application is not published on the Play Store. It is installed using a link to the apk on our local network. We do install apps and app updates one by one. We already have around 100 scanners. So, it's a pain updating all those one by one.
The question is: Can an in-app update be implemented in this way? I mean, without using the Play Store? Like writing in-app update code in the main activity but pointing to the link to the apk on our local network instead of the Play Store.
In other words, putting the new apk on the local server and using the link for the in-app update code, instead of uploading the app to the Play Store?
I've been looking for information for a few days unsuccessfully.
NOTE: I'm trying to do this out of the Play Store because the scanners in the production environment do not have internet access for security and safety purposes. They only have access to the local network via Wi-Fi.

An app can update itself (see e.g. f-droid store), but to actually install the app update Android shows a user consent page where you have to select the "Install" button. Only system apps can install apps without user consent.

MDM solutions are also an alternative, as they may also provide a built-in store to push app updates to multiple devices directly.

@Robert, do you have any tutorial that I can follow, I'm completely new on this. So I'm kind of lost. I checked documentation, but not sure if I need to create kind of a local f-droid store or something like that. Because remember that the devices have no access to internet. Also, each device needs to have f-droid app installed on it?
Thanks in advanced!

@AndrewT. Which MDM do you recommend, please let me know.
Thanks in advanced!

You only need to download the APK file and then trigger installation for the APK file. There are a lot of examples on https://Stackoverflow.com. How you organize the apps on server side is up to you.

Can I run an Android emulator (with GUI) on a headless Linux server?
I have a hosted server that runs the Ubuntu server, and I was wondering if there was a way to run Android applications and get access to the Android GUI remotely, such as with a remote desktop. Also, is there a way to set up this without installing a complete GUI on the remote server to preserve resources?

Have not used but aware of: AOSP- Cuttlefish Virtual Android Devices

It's commercial, but Canonical's AnBox Cloud should be able to do what you need. It runs Android in containers and is intended for streaming Android games, but that is not its only use.
I looked at it for on-premises software testing, because I had test data that I wasn't willing to put on a cloud platform, and Canonical reckoned that could be done.

Android app drawer hides
It happens on my Samsung Galaxy S4. Here is when the issue happens:
I go to applications and hold & draw an application to any folder. Before I do this, my screen looks like this (I can see the Messaging, Contacts, Phone and Apps icons):

However once I drag an app from applications screen to any folder, the bottom bar goes away. I am not sure how to get it back. Please note that the apps option is no longer available.

It gets resolved once I restart the phone. How else to resolve this? If not, at least how to get back my bottom aaps bar once it goes away?
My Android device info:
Model number: SAMSUNG-SGH-I337
Android Version: 4.4.4
Baseband Version: I337UCUFNJ4
I am running stock Samsung UI

Not really answering the question – but the simplest solution would be trying an alternative homescreen/launcher. Apex and Nova are good choices to start with.

Why does the play store require multiple account login to display my apps in the Google play store
I recently changed my 2nd gmail account password.
When I open the play store to check my apps it gave an error:

Authentication required. You need to sign in to your account. (click image for larger variant)
Whereas I have already logged in my first Google account  then why does it require the second account to be logged in when I haven't used this account any time for any Android apps till date.

Pretty easy to answer – let me use an example:
I add your Google account as my secondary. Now I log in with my primary. Would you be happy if I wouldn't have to authenticate for the secondary now? That would enable me to do all kind of stuff "on behalf of you".
So, putting it in short terms: Security concerns. Whether you have logged in with the second account from any apps or not doesn't matter – that account holds personal data, which must be protected.

I don't get it I have an account a@gmail.com for which i download apps and have an account b@gmail.com which i only used for checking mails in gmail app(i.e a is both checkng mails in  gmail app and download,whereas b is only for checking mails). Now as you say that for security concerns that both the accounts a and b are required for the play store.Previously it was only a single account required to login but now it why does it require two accounts wasn't there any security issue before when the Play store had only a single account access?

Authorization for Google Services is kind of "single sing-in" AFAIK. Obviously the Playstore app checks all configured accounts. Using b@gmail.com for Gmail (or any other Google service), you'll have to sign within that anyway. If you wouldn't use it, you hadn't configured it – I'd guess that's the logic behind it.

How to Unroot " Galaxy tab 2 p3113 8gb wifi "
My 9 year old son rooted his tab on his own, against my wishes. I tried a factory restore and used Kies to load via PC although this did not restore the tab.
It's still showing as rooted. Can anyone help as it seems he should have installed software prior to rooting from what I have read. Is there anything I can do to restore it to factory-defaults? Please anyone who can give suggestion I would greatly appreciate it.

I would recommend doing a nandroid backup before messing around with it too much. If you have a custom recovery installed, such as TWRP, you could download the stock ROM of your specific model (or really, any rom you wanted), and flash it via custom recovery. I highly suggest backing up prior. Once you do this everything should go back to how it would be if it was a brand new phone (besides the custom recovery - but this is more beneficial than problematic.)

Just reinstalling factory ROM will remove root access. I am assuming he has a custom recovery image installed? Also, how exactly is it showing that its rooted? Is a superuser app installed? Stock ROM?

How to unlock the Lock Screen in Android Lollipop
How can I unlock the screen lock in Android Lollipop without losing data?
I have forgotten the pattern.

I have just added the locked-out tag to your question. Please follow up to its tag-wiki for first-aid. Hint: Answers on Can not unlock my Android device as have no internet connection? cover pretty much any known method concerning your issue.

method 1Try using adb pull with the android SDK
In recovery mode.
method 2If you have a phone without an SD card wiping data will only remove the apps otherwise the data will be fine. This works even in some phones without SD card.
method 3 easiestAfter several tries it will give you option of forgot password. Which will ask you Google account details. Fill it and you are good to go.

How do method 1, or method 2, unlock the phone?

Recover photos and/or bypass lock screen on Android 5.0
I have a Samsung Galaxy S5 which I dropped on the ground so the screen broke. I had a swipe lock enabled. To be able to unlock it before it was repaired I locked it through Android Device Manager and tried to send commands to it from ADB. I was unsuccessful. The phone was repaired but wasn't wiped but now I can't access it. It keeps saying incorrect pin even though I know I've entered the pin I set through Android Device Manager.
I can't seem to set a new pin through ADM it says it's not needed since it is already protected by a pin.
Is there any way I can access my phone? Either:

Backup my pictures and then reset the phone
Bypass the lock somehow (I have ADB access and debug mode enabled)

I've tried all sorts of guides with ADB shell to remove *.key files but they don't work either because I don't have permission or because su or sqlite3 doesn't exist.
I'd prefer if I could keep the stock android image on the phone.

I've just updated the tags on your question. Two places you want to see first are our locked-out tag-wiki (for bypassing the lock screen), plus the data-recovery tag-wiki for the other part of your question. Our tag-wikis often contain some first-aid or links to the "top" related questions – always a good idea to check :)

Thanks for the suggestion. The locked out wiki seems to apply to older versions of Android and/or rooted devices. As for data-recovery, it seems to be for deleted files. My files are not deleted, just not accessible.

There might be some version-specific hints in, but also many version agnostic hints (as e.g. installing that app to disable keyguard, see second item). As for data recovery: here you're right, the wiki focusses on exactly that – my bad, sorry for that. Though I still thing the tag is correct, as the data is currently inaccessible to you.

The Screen Lock Bypass specifically says "This app will not work on Android 4.1 or above" so it's not version agnostic.

Ouch – sorry, I didn't check the app for a while. What about the ADB tricks mentioned there? I know, you've tried "something" with ADB – but was it especially that?

Chromecast Google TV: rotate output to display with default portrait mode
I recently bought a Waveshare display to connect my Raspberry Pi (RPI) to it for showing Home Assistant info. The display also has a second HDMI port which I would like to use to connect my Chromecast Google TV.
However, the default resolution (EDID data) is 1080x1920, so by default a portrait mode display. In my RPI, I can rotate the screen to 1920x1080. But I'm still looking for a solution for rotating also the Chromecast GGTV.
I already tried to install a "screenrotation" app, but nothing happened. I also tried to connect to the screen through adb and run some commands, but not the result I was hoping for (I got a message that the Chromecast did not support that resolution).
Today I found on the internet an EDID emulator. Could this be a solution? These are the EDID timing parameters of the display:
Pixel Clock  H Addressable  H Blanking  V Addressable  V Blanking  H Front Porch  H Sync Width  V Front Porch  V Sync Width  H Image Size  V Image Size  H Border  V Border
141.12       1080           120         1920           40          40             20            2              5             1080          1920          0         0

Any idea how to solve my problem (if there is a solution)?

Percentage reach a certain number then stop when trying to download an app from Play Store
When I try downloading an app on Play Store (even if it doesn't take up a big space), it would reach a certain percentage and then just stop. I tried waiting for a bit however; when I do, I get a weird message that tells me that I can't install the app.
I've never had this issue before. I have plenty of storage in my phone; I have the latest update on both my phone and Play Store; my WiFi is relatively good and usually installing apps wouldn't take seconds. I had tried restarting my phone; clearing Cache and doing a bunch of recommended stuff, but when I try to install the same app, guess what? It stops at the same percentage.
Please help me fix this problem. I don't want to abandon my account or remove data from my phone (OPPO Reno5 5G).

I once had this problem. I went to the website/review of where this app was mentioned (using mobile browser) and it had a link to the app. Clicking that took me to Play Store and it installed fine. Before doing all this I may have rebooted too, don't recollect

Welcome to the Q&A site Android Enthusiasts Stack Exchange. We have a few questions about a similar issue: Google Play Store download stops to a certain percentage on large programs, Why can't I install anything since Google Play Store downloads don't reach 100%?.

Banking apps disabled in Android SDK emulator
Does the Android SDK emulator run apps with FLAG_SECURE used from Android 12? I have been trying to run different banking apps, which work but crash when I get to the login screen which is flagged with the recent security options.

Usually banking apps are limited to physical device, emulated devices are not accepted as they have a higher chance of being insecure as they run on an unknown host system which can in general access anything within the emulator.  But that has nothing to to with FLAG_SECURE. This flag only disables screen shots for an activity.

/system/sbin in $PATH variable, but the folder doesn't exist?
I have a Chainfire-rooted Samsung Galaxy J5 with Android 7.1. The $PATH variable is
/su/bin:/sbin:/vendor/bin:/system/sbin:/system/bin:/su/xbin:/system/xbin

But /system/sbin appears not to exist at all.
Why is this? Is it normal? Could the manual creation (and planned use) of this folder cause problems? (I run into huge ones, but not sure this was the cause.)

(I probably have made several mistakes, and I will post my questions one-by-one to avoid confusion. This is the first.)

You can put any directory on PATH. They don't necessarily need to exist. init sets the default PATH on boot. /system/sbin was removed in Android 11. Related: How to modify environment variables like PATH at startup?

Thanks. It could be only a coincidence, but I run into troubles just after having created this folder. So I wanted to be sure if this could cause it. (lot of commands, like even "ls" stopped to function: "not found"...etc.)

APK updates showing on Aurora (3rd-party store) before Play Store
I noticed this yesterday.
I went onto Play Store and had "10 app updates available".
I then went on to Aurora Store and there were "125 app updates available".
I checked the version number of a few apps online, and it did seem as though the updates were legitimate.
My questions:

Are the updates on Aurora Store legitimate?

And, if so, why are they not showing on Play Store?

I hadn't heard of this so I installed it today... Aurora showed I have 7 updates available, and the Play Store showed I had 12... Weird.

Aurora Store is same as Play Store

Aurora app source is Play Store. Aurora Store says

Overall, Aurora Store is an intriguing app, that completes two functions. First of all, it makes it easy to download virtually any APK offered on Google Play, and second, it enables you to manage the apps already on your device. All from an elegant, intuitive interface.

(Emphasis added)
This makes it clear that the source for Aurora is Play Store. Also the FAQ has this

Is it safe to use Aurora store?

Aurora Store is fully open-source and verified by F-Droid. If you're asking about the safety of the apps in the store, those are the exact same ones the Play Store would load and display. A lot of dangerous stuff seems to sneak past Google though, so as a rule of thumb, don't download anything which you're unsure about.

Why does Aurora show more updates than Play Store?

Play Store follows Release app updates with staged rollouts. This could be the reason why you see less apps available in your region, Staged rollouts are:

New and existing users are eligible to receive updates from staged rollouts and are chosen at random for each new release rollout.

Your app update will be available to the percentage of users in your staged rollout, but it may take time for the full group to receive the update.

Users won't be notified if they receive a version of your app in a staged rollout.

If you choose specific countries for your staged rollout, the upgrade will be limited to users with Google Play accounts in those locations.

Robert's answer gives additional reasons for staged rollouts
To summarize, you won't see all app updates available on Play Store
Aurora Store is legitimate
The updates in Aurora are legitimate Aurora store is open source hosted on Github and the latest update to readme says

The source code for Aurora Store is actively developed on GitLab. You can find the latest updates, contribute to development, and track the progress on the Aurora Store GitLab repository

Hence, there is no reason at all to doubt the authenticity of Aurora Store. As a side note the developer of Aurora store is also the developer of Warden which is a tool for privacy conscious users, since

Detects Trackers & Loggers across whole device

Allows to disable all trackers/logger

App developers usually don't publish app updates immediately to all users. Instead they publish new app versions only a small subset of users (may be 5-10%) that is increasing over time ("staged rollout").
This is a precautionary measure, because if something goes wrong e.g. an app always crashes on a certain device or on devices by a certain manufacturer then this can easily lead to a denial-of-service attack against the app support (e.g. a forum) when millions of customers trying to reach the app support.
The Aurora Store uses internally Google Play Store but using a different account. Therefore it can happen the Aurora Store account is in the group of accounts which get access to the app update earlier, therefore in this case the app update is visible earlier in Aurora Store.

Connecting Samsung Galaxy Note 8 to a hardwired Ethernet
Has anyone been able to connect the Galaxy Note 8 to a hardwired Ethernet network?  If so, what adapter was used?
There are times that I cannot use the Wi-Fi and need to connect using a wired network.

Welcome to Android Enthusiasts StackExchange, what are you asking for exactly? A recommendation on the type of adapter or similar? Please read the [FAQ], recommendations are off-topic. :)

@t0mm13b Let's forget that this is a recommendation question. It looks like a valid question. I'm also interested to know if we can used wired connection with the tablet, and if there are devices / adapters that make it possible.

How to make Ethernet work on Android over OTG?

The short answer is no, there are no USB-to-ethernet dongles that the Galaxy Note 8 recognizes. The long answer is Galaxy Note 8 only supports wireless network connections unfortunately; however that could change if Samsung decides to include support for wired ethernet dongles in updates to the Note 8.

This is what you are looking for...

But does the Galaxy Note 8 include drivers to support its use?

Apps won't install or update after I cleared files and data
My phone is a mess right now. I cleared some files and data. Now, my Play Store stopped functioning. All my apps won't give notifications anymore. What should I do to fix this huge problem? I just uninstalled all the apps, and they won't let me install or update them again.

Have you tried doing a factory reset? In my Samsung Galaxy S4, it's in: System settings > Acceounts > Backup and reset > Factory data reset. See if you can find something similar to your phone.
WARNING: You will lose all your data when you do a factory reset. But since you uninstalled all your apps, it shouldn't be any problem / issue.

Download or get the Instagram video I saw earlier
Device: Samsung Galaxy S3
A person I followed had a cool video they posted on Instagram, but then deleted it later. I was wondering if there was a backup of the video in the temp folder, since I watched it earlier?

See if the answer here helps: How to download photos (of others) from Instagram?

The location of the Instagram cache is storage/android/data/com.instagram.android/cache/video
However, when I look on my device, it seems that the files are not stored in a traditional video format. You should be able to find the video there, if at all though.

storage/android/data/com.instagram.android/cache/video/
change the file extension from .0 to .mp4

Running MX Player on a Nexus 10 to access an ext4 USB Flash drive
How would I play an MP4 on a USB Flash drive connected to the Nexus 10?  The drive was formatted with Ubuntu with ext4 format.  I have the MX Player but it does not see the USB Flash drive.

First question: Assuming you are using an OTG cable, is your phone able to detect the USB drive using a file manager?

Yes, I have an OTG cable. I haven't seen a file manager on this Nexus 10.

Try installing File Expert or something similar. Let me know if your phone can see it.

I've installed File Expert HD.  I'm not familiar with this application but I don't seem to be able to find the USB Flash device attached via OTG cable.

See my latest answer. Try using a different OTG cable. Or try the app I suggested.

Usually Android can use only FAT32 because of permissions in ext file systems. If you have a terminal emulator installed + root + busybox you can do it like that:

Open terminal;
Type su to get root;
Insert cable and flash drive;
Type dmesg to get device name;
Make a folder using your file manager;
Try to: mount -t ext4 /dev/(device name) (path to folder you make);
Enter the folder: cd (path to folder);
Change the file permissons: chmod 777 (your file);
Go to that folder with file manager and play.

Or you could just use StickMount.

Google+ app does not launch live video hangout
Device: Nexus 4
Android: 4.3
When there is a live video hangout, the Google+ app makes a button available on the post called Watch Hangout On Air. However when I press it, YouTube launches the What to Watch screen, but the hangout video isn't in the list and nothing auto-plays.
The live Hangout is occurring. I can watch it on my laptop by using the same G+ post to launch it as I'm trying to use from my phone inside the app.
I've cleared the App Defaults for both the Google+ app and for YouTube. The Hangouts app has no defaults set yet.  My apps are all the latest versions.
I've used the back button in the YouTube app and have backed right out of it altogether, just to check that the live hangout video isn't hidden behind another screen activity.
Does anybody have any suggestions?

Not sure if this is it. From Google Support:

The YouTube app won't work with Hangouts On Air. So if you use
  Hangouts On Air, your viewers will only see the video call, not your
  playlist or the videos.

You were correct. The new YouTube 5 app released this week supports Hangouts On Air.

The YouTube 5 app released this week (Aug 20, 2013) supports Hangouts On Air. The previous version of the app apparently did not.

Not getting current location even if Location Services are enabled
Device: Samsung mobile phone
Android: 4.0.3
My Location Services are enabled, but I am not getting the current location. When I restart the phone, it works.
What could be the problem here?

So is it working now or does it stop working after a while and only a restart fixes it? And what app aren't you getting the location in? I've had a similar problem when developing an app (see http://stackoverflow.com/questions/13594932/network-provider-not-providing-updated-locations) but there isn't any known fix for the issue.

No, I cant able to found out the fix, can you have any solution regarding this

Nope I never did find a solution, neither did anyone else as far as I know, I just restart the phone occasionally if it stops working. Is it Google Maps that it isn't working in though? Do you have the latest version? I've never seen that problem on there.

so what's the the alternate way you are using for this fix, because i am getting this issue in several Samsung devices.

Can you Disable Wi-Fi and Bluetooth from Google Apps or a MDM Server?
This page claims:

Wifi configuration from Admin console - Enter Wifi network settings in
  the Admin console, and they’ll automatically be pushed out to all
  managed Android devices.

Does this mean just connection settings, or can it be disabled remotely?

From looking at that page, I'd say it's just the connection settings. I don't think you can completely disable Wi-Fi and Bluetooth.

Exchange ActiveSync allows you to disable Wi-Fi and bluetooth.
However, I'm not sure for Google Apps. Can't seem to find the information on their Support page.

Do you know if that particular ActiveSync policy is compatible on Android? I cannot find the API for it

@h00j I think the policy is supposed to be defined in Microsoft Exchange ActiveSync.

I understand that, but
Do you know if that particular ActiveSync policy is compatible on Android

@h00j I would assume YES. I have a corporate Exchange account on my phone, which disables certain options (like I should use only PIN lockscreen; other types are disabled). I would assume disabling Wi-Fi and bluetooth would also work.

Enable dialer autocomplete feature in Android 4.3 on Galaxy Nexus
My phone was upgraded to 4.3, as I see in the Settings.
How can I enable the dialer autocomplete feature in Android 4.3 on Galaxy Nexus? I don't see any Dialpad autocomplete in my phone app setting.

Could tou post a screenshot of your call settings?

From mybookofknowledge:

Go to your Dial Pad and select the Settings options.
Under the other call settings, you can see the option Dial pad autocomplete.
Enable this option and now you can see suggestions when you dial a phone number.

NOTE: Make sure you are using the stock dialer.

Why does Phone storage get full with ambiguous "Other" storage that wont let me use more than one GB of the supposed four that i have
My HTC keeps running out of phone storage, there is supposed to be four GB of storage but it always gets full at one GB of app data and 3 gigs of "Other" data which isn't cache and I can't even see what it is, I've had this problem with previous HTC phones, I've done what I can to move as many apps to my SD card but most can be moved there. What is this Other, is it important data, and can i move it or get rid of it.

Screenshot (click it for larger variant)

Have you checked what is shown when it connects to the PC? Does this memory appear when you connect to PC?
Try using a file manager to browse the files of your phone, and look for anything unusual.

"Other" is just anything that doesn't fall into one of the other categories.  If you install a file-manager app (such as OI File Manager) you can browse through the actual files and see exactly what's there.

Please any ideas for installing settings.apk to system without root on 4.4.3?
I will answer any questions you have for me....but I am just in need of an answer to the question as posted
I cannot access the settings on my device, as the settings app is not showing on the installed system applist.
Simply put, it seems the setting.apk must be replaced to save the phone.

non rooted
kitkat os 4.4.3
sgs4g
no usb hub working on unit
no recovery working
no settings menu access
(therefor, no dev settings menu either)

i have :
good full twrp recovery backup
good generic flash .image
(recovry can be set up once root is achieved)
Thus:
I have:
good apks/apps to get root access cable free
(but this can only happen when I am able to install apps from unknown sources)
I look forward to your comments
Thank you
and thanks Izzy for the suggestions

you said : but this can only happen when I am able to install apps from unknown sources - why you can't ? do you touch Unknown Sources for install? i can't underestand what you want exactly :-?

my problem right now i just need settings menu to work, which it does not.... due to the settings app not showing on the installed system applist

"i think",without root you can't.it's better to flash a rom only.

i can not flash...as noted in body of question; "no recovery working, no root, no usb hub". i simply need to see if anyone knows a way at all to install or enable the settings app, cause it may just be disabled

scenario ;  flashed a rom and after all settled lost bootload recovery twrp somehow, lost root, and no settings menu.... and to top it off the usb micro hub does not work.  what would you do in this case ?

i have one idea, if you can get access on number > keypad then you can use this code's for example : *#*#7780#*#* or *2767*3855# for factory reset or full reset.maybe it can help."but maybe..."

Suggesting a little more, as this time it got much clearer: If the settings app is not visible, it might simply be disabled (should not happen usually, but it might). If you've got a file explorer, you could check (/system/apps is usually the place it resides in). In that case, there are ADB commands to re-enable it or, worst case, a factory-reset should restore it. // Btw: If that turns out to be the case, that was a classical XY problem :)

okay thanks Izzy for joining.  and yes in conment above from 6 hours ago i stated it was possibly disabled .... i am ready to run some commands in term if you have something i can run.  please please. itd be great

M4T -  thanks i have been attempting all kinds of codes, but I get no reply when executed.. maybe something reaching out to cell network settings in the UI cause its blank as soon as code entry is completed (dialer digits dissapear but nothing happens). anyt other ideas...throw it my way...i am hoping the app is disabled and i can enable it..., thank you sir

hey Izzy,  you got me there..been dealing with this XY my entire life.... my apologies and nice link there... i will attempt to persue the proper agenda and better help others assist me. thanks again

What is the Lock Screen?
I don't understand the concept of "Lock Screen", can someone explain it?  Is it the main screen?  I have a Moto G 2nd gen.

Welcome to Android Enthusiasts!
While the community here is based around answering questions, we expected that the person does some research on the topic before asking a certain question. For example, when you put the name of your question as a Google search query, the first result directs you to the Wikipedia article which answers your question perfectly.

A little search on our site helps as well. Hint: our tags are sometimes a great resource, as they have "tag wikis" explaining their means. In your case, the lock-screens tag-wiki answers your question, which is why I've added that tag to your post.

The lock screen is the screen that shows up when you first turn on the phone, or wake the phone up.  It is the first layer of defense for your phone.  You have many options:

No lock screen(least amount of defense.
Swipe motion(which means you just have to swipe it to open it up)
Face recognition(which when you want to unlock your phone, you will have to face it and it will recognize your face with the camera)
Pattern lock(which is just as it sounds, gives you 9 dots and you have to make a 4+ pattern to unlock the phone)
Number lock(where you pick a 4 digit code that you must input before you can unlock the phone.)

if I know nothing about Android, is it crazy to have a rooted phone?
I bought my first Android phone off ebay, a Samsung Galaxy S4 after always using Windows phones.  It was supposed to be unlocked and a "store demo", but when I started playing with it, I was getting warnings that it was rooted and couldn't update in the regular way, etc.
I tried to update using Samsung Kies, which gave me a ton of errors, I had to do it four times.  This was the error message I kept getting:
http://i136.photobucket.com/albums/q161/Arylkin/1%20error.jpg
Then I got an error that I needed to do "emergency firmware recovery":
http://i136.photobucket.com/albums/q161/Arylkin/error%202.jpg
I finally got it to work (I don't know what kind of update it was, because it's still running the same Android version after it).  I got it to work by just ignoring the emergency recovery message and hitting continue (or something).
I am apprehensive about keeping this phone, since while I really do like it, I am worried about having some fiasco and it refusing to update down the road.  Also, every tutorial about rooting and "flashing roms" (whatever that means) and doing anything to a rooted phone says, "WARNING- YOU MIGHT JUST BRICK YOUR PHONE!".  Needless to say, this worries me.
The seller is willing to take it back, but now I've already bought a otterbox case for the S4 as well as additional batteries, so I'm kind of roped in to having an S4.
What would you do, return it and try to find another person selling an S4 that is stock?  I really don't know anything about Android, and even after reading tutorials, I'm not really comfortable doing a bunch of stuff to the command line of my phone or whatever, particularly since there are 1,000 warnings that doing so might totally break it.
Even video tutorials on rerooting or whatever have a bunch of comments like, "Now my phone is broken!  Thanks a lot!"  Everything I read says how rooting is the coolest ever, but I really don't want to break it since I will not be able to replace this, financially.
I'd appreciate any words of wisdom!

Some relevant posts: http://android.stackexchange.com/questions/236/what-does-to-root-a-phone-mean?lq=1, http://android.stackexchange.com/questions/1/ive-rooted-my-phone-now-what-what-do-i-gain-from-rooting

You might wish to see our rooting tag-wiki and root-access tag-wiki for that – they contain the related information, or at least the links to it.

If it's rooted, leave it be. It's very unlikely for the S4 to receive many (if any) more Android OS updates officially since it's now a couple of generations old. I use a rooted S4 myself, and love the fact that I can remove bloatware at will and make backups of everything.
With that being said, some more info from your device might help us direct you to info on your particular ROM if you have one, and how to lock it back down if you still so desire. Go into Settings>About Phone and see what Android version you're running and the build number for starters. All of those scary warnings in forums are there for a reason: with root you have unrestrained access to the very innards of your phone. If you start changing things in certain areas you can mess things up. However, it generally takes more than doing everyday tasks to do it.
Armed with the information from the About Phone section, head over to the XDA Forums to find out just about anything you'd ever want to know about that phone, along with some generally very knowledgeable and helpful people.

Thanks, I feel a little bit better. I'm running 4.4.4 and with build KTU84P.M919UVUFNK2 (model number SGH-M919).  I would just be sad if I couldn't get the lollipop update, or any  future update, whenever it comes out.

If it's already rooted, I wouldn't worry about it.  I wouldn't let it do any OTA updates, though.  I rooted my first phone without knowing much about it, and it was fine.  I use root mainly for apps like Titanium Backup, which is just great.  You can backup and save all your apps and app data, as well as remove any bloatware that normally comes with the phone.  You can actually get rid of all the apps you don't want/use.
When I rooted my S4, my phone stopped getting the OTA updates.  If it's important to you to have the latest and greatest version of android, then yeah, you might want to get rid of it or unroot it.  If you don't want to deal with the hassle and like you phone the way it is, I would keep it.
I would definitely check out these forums here.  Who knows, you might find a new hobby.

Sony Xperia Z3 (Compact) Battery life after update to Lollipop
If you already updated your Sony Xperia Z3 (Compact) to Lollipop, what is your experience (and what we can expect) with the battery life in Stamina mode while the phone is idle?
Xperia can have couple of days of light use when on Stamina mode and Hangouts/LocationHistory off in KitKat.
Is it comparable, does it get noticeable better or worse after upgrade to Lollipop?

Screenshot (click for larger variant)

That's quite impressive; I'm assuming you've got Ultra Stamina mode enabled to get that? (so, Wifi off when screen is off etc etc).
I've not seen any noticeable difference myself after the upgrade, but I only have Stamina mode enabled with 'Extended Usage' and 'Queue Background Data' turned on.

Yes, I ask about the Stamina mode, where is the biggest advantage of the Xperia prolonging the battery life when you don't use the phone often. If you have an experience with Stamina Lollipop, feel free to answer below. I would also appreciate to see a screenshot of your battery stats, if possible.

I can't speak to Stamina mode since I don't use it often, but I had great battery life in regular mode on KitKat. With light talking, texting, and browser/FB use, I could easily go more than 24 hours without recharging my phone. Since upgrading to Lollipop (4-5 days ago), my phone goes from 100% charged at 7am to 7% charged at 5pm -- with very little use -- terrible!  I hope there's a patch for this, b/c I am so disappointed. No real visible upgrade to Lollipop, so frankly, I'd rather go back to KitKat.

I would like to downgrade to kitkat as well. The question is how to do that?

My battery life started to deplete very quickly after upgrading to Lollipop. I experimented with Stamina mode to try to get back to the battery life I used to have on my Z3C, but it actually made it worse! Google play services was keeping my mobile radio active almost 100% of the time. I moved back to regular mode and I'm getting about 15-20 hours of battery with normal use.
Google play services still consumes the most battery on my phone, but it seems to be at least reasonable now. Definitely looking for a patch or some sort of fix - very disappointed.

I have the same problem for xperia z1 compact

My friend saw a huge decrease in battery duration after making the Lollipop switch. The battery would not last a whole day with light usage.
Her workaround is to disable location services when not using them. This prevents Google Services from activating, which apparently is a currently a huge power drain in this build. Now she is back to at least a couple days between having to recharge.

how to reset the phone pc after too mant pattern attempts
How can I reset my android phone HTC desire HD after too many attempts. I want to reset my phone via connecting it to PC . I don't know how reset it from PC and even I can't reset it from buttons because volume buttons are broken.
Now please somebody tell me how can I reset it from PC.

I see you've got a big problem and are "bold" enough to ask it – but that shouldn't end up in all-bold-letters, please :) Bold is for emphasis – and emphasizing the entire post makes no sense.

There are multiple ways to do this, most of them requiring adb being available on your computer:

How can i do factory reset using adb in android? gives this solution:
adb shell
recovery --wipe_data

How to Hard Reset or Factory Reset and Format Android Phones and Tablets gives detailed instructions on doing this with fastboot (including setting up your computer for that). The command finally doing the job is:
fastboot erase userdata

Doing that, I'd recommend to also include a fastboot fastboot erase cache (recovery --wipe_cache if you use the first approach).
If you had setup other means of accessing your device's command line interface from your computer (e.g. SSH), you can use the first command (recovery --wipe_data) from that shell as well – without the need of ADB/Fastboot.

Why is the battery usage graph so useless?
Is it just my phone (Nexus 5, 5.1) or did the battery usage graph become useless in Lollipop?
I've attached a graph from today that, at first (and second) glance, makes no sense at all. This is after about an hour of sitting idle with the screen off.

If someone could please explain what's going on I'd really appreciate it.

What happened to the other 97% of usage?

Also, I did ask for someone to explain what's happening. So if you know what's being shared in the image you should be able to provide an answer, correct?

The percentages do not refer to actual battery use, e. g. on your device, those 1% marks don't mean that specific application has used the 1% of the battery.

Yes. It has become rather useless. You can't know how many hours passed since you unplugged it, and now the percentages do not add up to 100% (as they should in any rational universe)

Export WiFi x509 client certificate
My Android (4.4) device has a WiFi configured which uses WPA2-TLS authentication with client certificates.
I got my hands on the wpa_supplicant configuration and the relevant entry looks like this:

network={
        ssid="fobar"
        key_mgmt=WPA-EAP IEEE8021X
        eap=TLS
        identity="000123"
        password="000000"
        ca_cert="keystore://CACERT_fobar_WPA_EAPIEEE8021X_TLS_NULL"
        client_cert="keystore://USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N"
        engine_id="keystore"
        key_id="USRPKEY_fobar_WPA_EAPIEEE8021X_TLS_NULL"
        engine=1
        proactive_key_caching=1
}

How can I get hold of the certificates and the key?

Go to :

/data/misc/keystore/user_0

And find the file's with similar name like below :
USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N

good idea, but how to make of the file contents?

i think these files automatically stored in this directory.and also, this information can help you : ca_cert="keystore://CACERT_fobar_WPA_EAPIEEE8021X_TLS_NULL"         client_cert="keystore://USRCERT_fobar_WPA_EAPIEEE8021X_TLS_N" for find and save.
