adb push: sync but not copy
adb push seems to push everything into the dest folder regardless of their changed/unchanged states. So it wastes a lot of time. Is it possible to sync rather than copy (i.e. to rsync rather than cp)?
I see adb has a sync option, but I'm not quite sure whether it's relevant or not.

You would use adb push --sync, for example:
adb push --sync /home/abc/ /sdcard/abc

from adb --help:

file transfer:
 push [--sync] LOCAL... REMOTE
     copy local files/directories to device
     --sync: only push files that are newer on the host than the device

but it seems that this function is available for relative newer ADB version such as version 1.0.40.

While this answer is not exactly an explanation on the usage of adb sync, it may help when your primary goal is to sync files using adb.
You may be interested in adb-sync which is a Python script that uses adb to synchronize files from your computer to your Android device or vice versa.
Example (computer -> device):
adb-sync /home/abc/ /sdcard/abc

Example (computer <- device):
adb-sync --reverse /sdcard/abc /home/abc/

If missing files on the source should be deleted on the target you have to specify --delete.

this python script works for linux only. for windows one can install bash and try winadb-sync

"adb sync" is not relevant in your case. It is used to sync system partition to your connected adb device. It will only work if your phone is rooted and you first need to put system partition into writeable mode. By default it is in read-only mode. Please follow this article for more details:
https://medium.com/@yigitpirildak/syncing-aosp-build-changes-using-adb-sync-885ce12e5cc7

I have made a python script that works like charm for windows.
It copies all the files from the current folder to the device(path can be edited in the code) except the files already present there.
Optionally, -l switch can be used to list the files with copy size before actual copy.
import os
import subprocess
import sys
files=os.listdir('.')
files=set(files)
devPath="/path/on/adb/device"
cmd="adb shell ls -a " + devPath
deviceFiles=subprocess.check_output(cmd,shell=True).decode().split('\r\r\n')
deviceFiles=set(deviceFiles)
filesToCopy=files-deviceFiles
size=0
count=0
justList=False
if (len(sys.argv)>1 and sys.argv[1]=='-l'):
    justList=True
for f in filesToCopy:
    count+=1
    size+=os.path.getsize(f)
    if(not justList):
        cmd="adb push "+str(f)+" "+devPath+str(f)
        os.system(cmd)
    print(str(count) + ' ' + str(f))
if(not justList):
    os.system("adb shell rm "+str(devPath)+"/"+sys.argv[0])
print(str(size/1000000) + " Mb")

When running adb without any commands, you get a list of possible commands, and here it is:
adb sync [ <directory> ]     - copy host->device only if changed
                             (see 'adb help all')

Looks pretty relevant to me :)

Would you please give an example on how to use this? Say if I want to sync /home/abc/ on PC to /sdcard/abc/ on device.

Did you try adb help all?

Yes. It can sync system/data partition. But I just want to sync one folder on sdcard. Do you know how to do that?

It is not implemented in version <= 1.0.31.

While this command looks promising at first, I couldn't get it to work after a quick try. A real example as requested by cyker would be helpful.

This does not answer the question in full, nor it works as the OP wants.

How did that answer get upvoted? It's not relevant at all.

Recommended Modem for Israel/Middle East with CM9 for GS II
My connectivity randomly cuts out - and after searching the CM9 discussion threads - I understand my modem is likely incompatible with my region.
I couldn't find a sticky or thread in XDA about recommended modems by geography - so I was hoping to get some advice here from your experience.
I have a Galaxy S II.
Thanks!

I think you might need to let us know which device you have before anyone can recommend software for it.

Which model is it? i9100G or the original i9100? Both have very different internals, just be aware of that.

Identify the Correct Modem
The Galaxy S II modems files usually contain a reference to the zone where they best apply. In your case, the first reference letter should be "J", that appears just after the phone model.
Official Firmware: July 2012

Middle East

United Arab Emirates XSG - I9100JPLPF/I9100OJPLPC/I9100XXLPX ICS 4.0.3
Israel Cellcom CEL - I9100TJIKG3/I9100TCELKG3/I9100TJIKG1

You can also find out your modem version by accessing the "About phone" menu option. The value of "baseband" is your modem version.

Modem File
The file Modem_I9100TJIKI2.7z should be the most appropriated for your location.

How do I open a tg:// URL on Android?
I have a tg:// URL like tg://login?token=BTGjK95sf6QLckQBAZPtH_gSLOcpQoasQLCea18O9A that I want to open in the Android Telegram app.
If I paste it into Chrome address bar then it searches for the URL, rather than redirecting to the app like on a PC.
How do I open this URL?

That the link is not executed is related to the Chrome address bar. If the link is contained in an HTML page it should work. A simple "workaround" would be to send the link in an HTML E-Mail to an account that is set-up in an E-Mail app on your device. Clicking the link in the email app on your device should open it in Telegram or whatever app the URL scheme belongs to.

I found a work-around using the Telegram app and the data encoded as a QR code: open Telegram app → tap the Hamburger icon → Settings → Devices → Scan QR Code.

This edit is much less readable.

How do I get rid of the search suggestions in Chrome?
I want to remove these suggestions on chrome for android, but I cannot find how to do it anywhere. Can someone help me with this?
Once I type a letter the normal suggestions appear. I just don't want to see all these recent searches I made.

They seem to be from your history. I don't see a toggle to turn off history suggestions in Chrome.

Sadly, there doesn't seem to be any way to do this without turning off History or using incognito mode.

Those are suggestions that you can turn off.

Go to the Chrome menu on the browser toolbar.
Click Settings.

How to completely block popups / dialogs from WhatsApp without deleting the app?
I have a Nexus 5 phone with Android 6.0.1 and I'm trying to use it for time-lapse videos ("Lapse it" app) which means it needs to be on for many hours undisturbed.
The problem is that WhatsApp creates a dialog regularly which interrupts the time lapse photo app that I'm using.
I have disabled all notifications for WhatsApp, but this dialog comes up anyway.
Deleting WhatsApp would of course solve the problem, but it not possible for other reasons (message history etc stored). Registering the app would also stop the dialog, but is also not an option since I'm using the same number on another phone.
I think it should be possible to disable all dialogs, but since I've tried that and this dialog still comes up, what else is there? Is there a stronger blocking option? Can it be done if I root the phone?
Attaching screenshots of the notification and of the settings.

Rooting would definitely offer more powerful options but to root you'd need to unlock bootloader and that would wipe all data. It's the same as the option you are avoiding (uninstall whatsapp) // You can't anyway use the device when taking a time lapse, so the simplest would be to put it in airplane mode, isn't it? // your second screen shot is confusing - if it is not registered, how are you getting messages on WhatsApp? Unless you are using that SIM on another phone

Sorry, I missed seeing the edit where you clarified the last point. Simply use airplane mode to solve the problem

Technically, that's not an Android notification, but a custom pop-up dialog. In this case, you're right that blocking the notification won't help. Possibly there's a background service that checks this periodically and shows the dialog. If that's the case, it might be possible to disable this using pm command.

How to fix "No SIM" issue after flashing stock ROM?
After using custom ROMs on my Motorola E4 Plus (Nicklaus) I figured out that there's no such custom stable ROM to install, so I recently flashed my device with stock ROM (Motorola Nicklaus MTK (XT1770)) but ended up with no sim support.
I tried to reset the networks but it didn't help me at all. I also reformatted the device and flashed with region specific stock ROMs too,
but that didn't help either. I flashed TWRP too. It showed OK while flashing using ADB, but recovery mode shows "No Command".
The problem is, currently I'm unable to use the stock ROM or to go back to those custom ROMs. Bootloader is unlocked. Every change has been executed properly as expected but not working on phone.

Please don't abuse quoting and font highlighting tools.

Does your device show a valid IMEI number, either in bootloader or by dialing *#06#? I am suspecting your EFS partition is corrupted and unless you have a backup is almost impossible for anyone but Motorola to restore.

@acejavelin no it isn't showing my IMEI number. And is there any way to fix this without backup?

There are some EFS partition backup files available on the net, you can try to use for recovery. I also had this problem some years ago on an old tablet. I never mad the mobile network back to live on that old tablet.

@Robert after researching on the internet I've found that the network issue ca be fixed on MTK devices if you'll be able to fix the IMEI. So going to flash the phone with the stock ROM and tweeking the nvram and nvdata entries.

Restrict app's background battery usage using terminal (root granted)

Is it possible to change this setting using termux?

Run: appops set <package> RUN_ANY_IN_BACKGROUND ignore; appops set <package> RUN_IN_BACKGROUND ignore. See Disable autostart on boot and restrict background execution. For more detailed and fine-grained control of AppOps you may check my open source app PMX.

I initially asked this question to figure out a bug-fix for an open-source app but it turns out it's in AOSP (see here if you're interested to learn it, https://github.com/MuntashirAkon/AppManager/issues/388)
Now, for Users who want to apply this setting to a batch of apps the best and easy method would be to use this app, https://github.com/MuntashirAkon/AppManager
From AM's prevent background operation option available in the batch operations.
There are should be many alternative apps such as https://github.com/mirfatif/PermissionManagerX
and App Ops which you can try and see what it offers.
This answer didn't cover how you can do it using CLI but you can check the comment by Irfan Latif if that's any help.

How to attach multiple displays to Android?
I would like to have an Android setup with one primary and two secondary hardware displays. I am wondering, if it is possible at all? I know you can have primary and secondary screens according to the documentation, and Android have Display Manager supporting multiple displays. But would a total of three displays work?
I am running Android 11.

I don't think you are talking about regular Android installed on some smartphone. You are talking about Android-x86 or some other Android-OS for PCs. Because usually you don't "setup" Android somewhere. A device comes with Android or not. The only other option is to change the AOSP source code and develop you own Android based custom ROM (a topic that is considered off-topic here).

Yes and no, you can plug Android device into HDMI extender and have at least 1 external display. Technically you can use multiple HDMIs to connect to multiple displays. I tried successfully with only with one HDMI.
But yes I'm talking mostly about AOSP ans it more configurable.
But it should be irrelevant as Android since version 10 has innate multiple display support.

So you are talking about displays connected via USB-C port to an Android phone? If that works and how (MHL, DisplayPort alternate stream, ..) is very device specific.

By "Android [...] 10 has innate multiple display support", is this you're referring to: Using more than two displays?

@AndrewT. Yes, exactly this what I'm talking about.

How can I access files on a Seagate GoFlex Satellite wifi or Kingston Wi-Drive?
My final goal is to programmaticaly access files on a Wifi/USB storage device, like a Seagate GoFlex Satellite wifi or Kingston Wi-Drive (preferred because less expensive).
The storage devices are made to be connected to a PC by USB and also can be connected to Android (and iPhone) by wifi.
Once connected, it is possible to put files on the hard drive over wifi using a custom Android application provided by the manufacturer (like Kingston Wi-drive or Seagate GoFlex Access™ app)? How do they do this? Can I access on my filesystem with program like Astro ?

I'm not clear what you're asking here. If you're looking for help with a programming solution, you'll want [so], not here. (Please read the [FAQ].) If I'm misunderstanding you, I think you're going to need to clarify your question.

not sure ... if you can access on that two device from astro or a file manager like this it means that you can access programmaticaly on that two device. If I put my question on stackoverflow, they will tell me that the question is android device oriented. So I'm not sure of  the correct web site

The fact that your question relates to Android doesn't make it off topic for Stack Overflow (nor does it make it on topic here). If you're trying to write a program to access the data then this is not the correct site. If you just want to access the data however possible (i.e. if "Use Astro" solves your problem) then this fits here.

well I don't know, my first need is use it with my application, but if someone has one of that device and he can access with an astro application, it should work

Well if you have two distinct questions then just ask one of them. "How do I access a wifi drive from Android?" seems perfectly acceptable here, and is an entirely different question than "How do I write an app to access a wireless drive?"

@P.Sohm I've edited your question to hopefully make it a bit clearer, as it wasn't easy to understand what you were trying to do. If I have got any of the details wrong, please feel free to correct them.

done. hope to be clear. feel free to correct it

According to this review Pocket-Lint: Kingston Wi-Drive review :

You are also able to access the files on the Wi-Drive on a PC or Mac
  by visiting it's IP address in your web browser. This, again, allows
  you to play any files that are supported in your web browser. MP3s,
  for example, play fine, but you might struggle more with video files.
You can also connect to the Kingston as a regular network drive. We
  were able to view it as if it was any network attached storage device.
  That means we could also copy files over wirelessly too.

This suggests that, the Kingston at least, supports something like SMB (the Windows file-sharing protocol). Many Android apps let you connect to an SMB shared drive to copy files on or off, I use File Manager to copy files from my Windows machines to my phone/tablet this way, and I'm pretty sure Astro supports it too.
To do this from your app, you just need to include SMB file access support in your Andoird app. How to do that is off-topic for this site, as that is a developer question.

well I know how to make a smb / cifs file access with jcifs. I already developed it. My need is only to know is how to access to that device and I think you gave me a good answer. thank you

Oneplus2, screen capture option disappeared after OS upgrade
I have a Oneplus2 device, recently (last week) I have upgrades the OS to OxygenOS 3.5.6. Among a lot of UI changes I have noticed that when I long press the power button I only get the "Power off" and "Reboot" options.
Before the OS upgrade It also contained a capture screen (for screenshots) button. Is there a way to bring it back ?

Looks like it's dropped. Apart from Vol dn + power option you have 3 finger swipe option

If your device is rooted, it is possible

well, my device is not rooted.. yet! but i want to avoid having to install another widget/app just for that

In which case, you may not be able to bring it back as it is not a supported OS feature ( and needs root to modify OS) - I don't have that OS but a friend who has was discussing this option and showed me the three finger swipe

Just tried the 3 finger swipe and it's pretty good. post your solution as an answer and I will accept it

Posted as requested

This feature is dropped from the OS update and you would need root pets to attempt restore or apply a hack. Since your device is not rooted, you can use Three Finger Swipe . Steps below :
Settings → Gestures → Enable Three Finger screenshot
By swiping the fingers from top down, you can take a screenshot. There's also an option of taking  a long screenshot by pressing the icon which looks like portrait device icon
I neither have the device nor OS, but saw it on a friend's device. Please feel free to add or edit

Is it possible to order 2 Ubers at the same time?
Using the Uber Android application, is it possible to book 2 Uber drivers at the same time?

Franck(ly), are you sure this is an Android specific question – and not rather a policy-related Uber question? Does Uber generally allow this? (as on SR, please include context ;) A good starting place might also be the Uber help center (yuck, do they only know the iOS app there?)

@Izzy Unsure, I didn't use the iPhone app. Perhaps Uber policy indeed :/

I'd say simply try it; if it works you'll know (and have to pay 2 drivers :)

And? Tried it? Wanna post an answer? I know you know that on SE sites, it's perfectly fine to answer your own question :)

It does not seem possible to order 2 Ubers at the same time: requesting an Uber changes the application interface, making it impossible to request a second Uber.

At what decibel does Android Pie shows high volume warning?
At what decibel does Android Pie shows high volume warning?

According to an article here by Kevin Arrows:

The reason Android phones [give high volume warning] is due to regulations set by the European Committee for Electrotechnical Standardization, which dictate that media playback devices must have a maximum output value of 85 dB – past 85 dB and the user must accept a warning.

So, the decibel limit might be 85 in Android Pie.

By "volume limit", did you mean "the maximum decibel an Android device can play", or "the warning threshold"? Note that the article is talking about "the warning threshold" that the user has to accept before turning the volume louder than that.

I was talking about the warning threshold. Not the maximum decibel that's possible on an android device.

What does this symbol means?

My friend is asking about this icon on the notification bar. Is it from a application or just find in page?

Good question and being a developer I know that an app can add their own icons to the notification bar.
Depending on your phone type you can long hold on an empty part of your screen and then down at the bottom you will see widgets.   Hit that and then scroll down or sideways to see if you have the Notification history widget.   If you do drag it to a place on your screen.   Then you can see what that notification is for.
If you don't have the notification widget you can install a notification history app that will show you your notifications and what they are for.
On the app that I downloaded while I was researching this answer I had to enable Save Non-removable notifications.
If the notification is on the left top then you should be able to swipe down and see what app it is for.
If the notification is on the right you MAY be able to see it in the notification app.
That icon does not look like a default android icon so it's probably an application .
Here is a list of a lot of icons and it might be in there as well.

How do I use ADB Input Events for users, other than phone owner?
I can easily automate input events using something like this:
adb shell input tap 300 300

And I am doing this, indeed, to automate configs exporting process for some owner installed apps.
Although, I would like to automate configs exporting process for apps installed by other phone users, but I had no success, so far. This is because other users can't enable ADB.
My phone is using Android 9 (Lineage OS).

@alecxs When I use ADB Input Events, the command is only going to work for user 0. I want to be able to use for users 11 and 12, for example.

so your question is how to enable usb-debugging for multi-user?

if that allows me to use input for other users: yes

https://play.google.com/store/apps/details?id=com.singlebyte.devshortcut

@alecxs I really apreciate it but there's nothing I can do, since I don't know how to enable developer options for secondary users on Lineage 16. <3

the app does not work?

@alecxs no because developer options are not enabled for the secondary user I tried installing the app. I also have tried enabling developers tools by tapping "build number" many times...

How to fix error messages (failed /efs unmount; failed to find misc partition) on stock recovery screen?
This Samsung phone was given to me. I had no clue about the frp when I reset it.  I wondered the easiest way to get past it because I'm like two days into starting to learn this stuff and I'd like my phone back. There are two messages on the recovery screen I don't understand. The first is:

E:ensure_path_unmounted failed to unmount /efs (device or resource busy)

I would also like to add that I did factory reset it once without the sim card in it I'm not sure if that affects anything.
The second message this one is at the bottom (the other is at the top under the menu says):

E:failed to open /dev/block/bootdevice/by-name/misc: No such file or directory

Actually reading through it there are two more similar to these two.

When you got the phone was it working?

Yes and the verizon software update and repair thing was working on it all night but I don't know how to put it into the proper mode to transfer the software to it without getting into the phone which I still couldn't do.  Oddly, I restarted it a moment ago and got a weird green screen with gears saying android was starting which I'd never seen before.  I tried all those tutorials where they get to google, I couldn't before but my screen isn't quite so monotone now so maybe I can now who knows.  I'll try and let you know.

ignore that messages, that are leftovers from previous rom version. missing misc partition is due a change to fota partition, most likely some lazy samsung developer forgot to fix recovery.fstab

Does this answer your question? How to bypass "Verify your account" (Factory Reset Protection)

frp = "factory reset protection", nice to know. Before you buy a device, first always google, does it have similar dishonest practice. If yes, boycott the whole manufacturer.

"Internet not available" error while trying to connect to wifi
I have a samsung galaxy chat B5330 device.
Whenever I try to connect it to wifi, I get various errors as follows,

Using DHCP :- Here it shows a "obtaining IP address" message but never connects.
Using Static IP :- It connects to wifi but then shows a "internet not available" error. I'm sure that internet is available as many others use it successfully using other android devices/laptops etc.

EDIT:
I found out that not all are able to use the wifi. Some do not get connected(stuck in "obtaining ip address"), some get the "internet not available" error, some connect and get internet but at very slow speeds(10 KBps download speed) while some lucky dudes get blazing speed(10MBps download speed)
Could this occur due to to many signals at same place? At any given place in campus, we get at least 2 strong and 1/2 weak wifi signals, not to mention some secured portable wifi hotspots from androids.
How do I solve this error.
Note that I don't own the router/wifi, it's open(No security, accessible by any student.)

Could that be a MAC filter on the routers end? Doubtful (if anybody else can connect fine with any device, even new ones which never had connected to it), but the first thing coming to mind.

@Izzy Could this be due to too many routers? There are 1 to 3 routers at every floor, so we always get at least 4 signals at any time(few from same floor and few from above and/or below).

I don't think so (or I would have the same trouble here, with always ~10 APs in reach). I'd rather say it depends on which AP the device tries to connect to, one of them might be the culprit. But that's rather not an Android specific question I bet. It better fits the "personal and home computer networking" topic covered by [SU] – as long as it's not "specific to corporate IT support and networks" (off-topic there).

Seems DHCP is not enabled on WIFI router, you may need to ask others to obtain DNS
address, to connect to internet, DNS info is required as well

I tried, but there was a time limit to answer my own question, was about to do it later when it timed out, but you were faster. I've edited my question now instead.

As you already figured out, there's SSHelper hosting its own .apk. But you might also wish to check with F-Droid, and find out there are even more SSHd's to download without using Google Play Store.
Edit: As it turns out, I wasn't aware F-Droid also features forums, and the above are only forum links. To compensate: You can also find some SSH Server apps on 1mobile, e.g. SSH Server. The website allows you to simply download the .apk from your browser, no login required. Other than with F-Droid, I'm not sure concerning their reputation, though.
Apart from that: In my experience, it's always worth checking the resp. dev's website, where they sometimes host their own .apk files for download. If not, asking them helped me as well :)

What you link to are forum posts discussing sshd's. But if you take a look at the actual repository, there are no sshd's availiable (unless you count the one included in the fullfledged chrooted version of Debian, Lil' Debi, that is a really cool idea, but seems a little overkill for just running a ssh server).

Ouch – sorry, unfortunately you are correct: I wasn't aware of the fact F-Droid also features forums. To make up for my error: please take a look at What are the alternative Android app markets? I'm pretty sure at least AndroidPIT has some of those servers available. AndroidZoom as well. I'll update my answer in a minute...

I use Termux which ships with a package manager that can install OpenSSH server using the command
pkg install openssh

Termux has a wiki page about using ssh here: https://wiki.termux.com/wiki/Remote_Access

Removing redirect link malware
I have Xiaomi Mi3 and it's not rooted. Every time I open a web page, both on mobile data and WiFi, and even with different browsers, I get redirected to other pages with ads and pages like this:
http://mobiles.digital/IT/Sweepstake/LP/index.php?voluumdata=vid..00000004-4837-403c-8000-000000000000__vpid..ca8d4800-fd5d-11e4-88ba-7eef5f3eb726__caid..5422e033-3dc6-4996-b128-7bf07d491d19__rt..R__lid..19777e53-9ce2-45a2-8073-ce9466d65506__oid1..7756b6f2-77b0-4db4-8d79-0faa4854c67f__oid2..b504e00f-54b7-4fd2-99de-09a0e4919980__var1..425682__rd..www%5C.%5Cyouradexchange%5C.%5Ccom&SiteID=425682

I have tried:

Many antivirus (including AVG premium app which was free this weekend on Amazon app shop)
Factory reset: inside settings on my phone
Hard reset: deleted cache and installed app.
AdBlocker plus.

But nothing worked.
Here's the installed apps on my phone: https://drive.google.com/folderview?id=0B2cFQ2PnOtfNT0NsMnZJY1NiT1U&usp=sharing

Is your phone rooted? 2) Have you tried an adblocker? 3) Can you share screenshots of the apps installed (if no privacy concern exists)? 4) Does it happen on Wifi , mobile data, or both?

1)No 2)Yes, ive tried adblock but 3) i'll share it asap 4) both thanks for good question gonna edit my post asap

Are you going to share screenshots (mentioned in the comment)?

For me the album link don't work even logged into google plus. Are you sure it's public?

@FedericoPonzi I agree with user3344236. The permission to view the album by others isn't granted yet; Please change it to public.

updated with gdrive

It seems you're infected with YourAdExchange malware (note the URL at the end). However, I still haven't found any clue to clean it on Android.

Andrew T. this can be a false assumption also. I think the correct title should be: removing redirect link malware on Android phone. :)

@user3344236 fair enough since I couldn't find any clue related to that malware on Android.

Recently there's a similar issue related to YourAdExchange. I'm not really sure if your case is the same as that, but you might be interested to try the answer before flashing the ROM.

I'd like to get more information to help. Could you show the MIUI version of your phone? See it in Settings -> About Phone -> MIUI version. If you can use adb in your PC? I think It will be helpful if you can show the output of PC command "adb shell pm list packages" and the output of "adb shell ls -l /system/app /system/priv-app"
By the way, if a factory reset can not resolve the problem you can try a full ota update which will reformat the system partition. To do full ota update: Click the Updater app, and then click the menu button in the right top, then click the "Download update" item. !Remember to backup your files!

The MIUI version is 4.10.17,  android version 4.4.4 . When i try to Download update i get a "no update available "message, so i can't do it. Thanks anyway!

4.10.17 is a beta version and is rooted by default. Did you get it from the MIUI's official website? (en.miui.com)

I actually brought it from xiaomi on Amazon

I think you can try to download a full ROM package to do an update and then do a factory reset. The official download website: http://en.miui.com/download.html

Try Avast free  and Malwarebytes , one after another (not 2 installed in the same time).
Try to move the app masked as com.securitycore.miui_t to SD card, then scan your phone again.
Reasoning:
I removed an "insane" pop-up linker (no matter what browser I used) which, instead acting like an activity by default (a malware activity) just used text displayed on webpage ( reading html meta tags ) and added link with advertorial content (manipulating content by adding div contents) or opening random links even if I visited “legit” and “clean” sites.
I recommended Avast for it's heuristic engine (IMHO better than AVG). Malware bytes actually marks threats and help remove some “non-detectable” adware (details about heuristic engine vs. databases containing signatures of viral code is out of the scope here).
Having in fact an extended experience with those kind of threats, my advice is a first step for taking countermeasures against this malicious object (script). I also see the user has a strange object acting like overwriting content or redirecting page.
So, after scanning with those 2 tools, the user may come back telling: none worked. How we must interpret this second problem? I think the key in this case is thinking about “where” antivirus and other products used did not look. As obvious, there can be two major places: /data/ or /system root folders. So, in case we still have troubles after scanning with some tools the solution which comes to mind is to go in /data/ or /system folders and manually remove application which we suspect (browser application, in our case).
Being aware the user has a non-rooted device, a simple solution is to use another browser after deleting/uninstall browser app which caused trouble. I hope the user has original ROM by Xiaomi and not a "modified" one (there were rumors about malware packed inside 'Xioami' counterfeit rooms, even if the device looks legit).
Readings for reference:

[Android] Android malware found on Google Play with millions of downloads
Popular Xiaomi Phone Could Put Data at Risk

From the settings page of the app, i cant find move to sd options. Seems like Xiaomi dosen't support move to sd natively. http://en.miui.com/thread-12681-1-1.html

Try to disable/delete/uninstall com.securitycore.miui_t (do not reboot phone) and see if browser still acts strange. I think it should be enabled again on reboot. I doubt  Malware bytes and Avast did not find anything strange...

Can't disable/delete/unistall it! Removed the data but the adware is still there :(

Are there any solutions other than flashing Gapps, to have Google accounts on CyanogenMod?
I've flashed CyanogenMod, nightly, and it is working perfectly. When I flash Gapps, then battery is drained fast, and the device is getting overheated. So, are there any solutions other than flashing Gapps, to have Google accounts on CyanogenMod?
P.S. I extracted the Gapps.zip, there was a folder named "apps" there, none of which could be installed. I tested installation using "adb", and got error related to certificate. I think by having ONLY Google Play Store, other apps can be installed, if I'm wrong, then please tell me what else is needed.
Thanks in advance

pretty much - google play store should let you install anything else. Might help, I suspect to give more details on your phone, cynogenmod version, and where you installed gapps from

My phone is HTC Sensation, and I installed cm-10-20131006-NIGHTLY-pyramid and flashed gapps-jb-20121011-signed. I downloaded them from cyanogenmod's official site and goo.im.

You might wish to take a look at the NOGAPPS project at XDA. It's not yet complete, but most parts seem to be in a working order already. NOGAPPS basically is an OpenSource replacement of most Google apps (including Playstore), often mapping to free alternatives (e.g. OpenStreetMap for maps).
Side-effect: More privacy, less tracking :) But keep in mind that some components are still in Beta (Maps, Playstore) or completely missing (still under development; Login Services, Services Framework), so it's not yet a full replacement of GApps. Still it might be sufficient for many cases.

I'm a fan of free software, but this seems to be in its  first steps :) thanks

You can try only installing the "core" Gapps apps. Choose your current Android version and select the "Gapps Core" zip. Then boot into recovery and flash it. Beforehand you have maybe to whipe your paritions in order to have a clean install.
http://goo.im/devs/BaNkS/GApps
If you want to install CM10.0 you need the Gapps files for 4.1.x
Edit other possible sources:
http://forum.xda-developers.com/showthread.php?t=2548351
http://forum.xda-developers.com/showthread.php?t=1809377

Which there is no downloads available for 4.1.x :(

Have you checked with CyanogenMod's GApps page? It lists which GApps correspond with what CM version. // Edit: Ah, I see: they have no links for "core only" packages :(

@Izzy Maybe I must consider compiling CyanogenMod and adding those packages by myself?

CyanogenMod does not include those packaes (for license reasons), that's why they're provided separately. I don't know where other (minimal) variants are provided, but I rawly remember having seen that.

@MostafaShahverdy I added some more posible sources for Gapps packages with reduced bloatware.

try from here http://goo.im/gapps

Battery drains very quickly on Samsung Galaxy S5
I have purchased a Samsung Galaxy S5 from the store. I open it and I begin by charging it for the first time, but without turning it on. The battery was 61%, so I waited until 100%. After that, I turned on the phone and proceeded to set it up. The version of Android was 5.0 Lollipop (I don't know how this is possible as I thought I need to update it myself from 4.4.2 to 5.0).
While I was entering in the information for the first time, the battery suddenly fell from 100% to 95% in just 5 to 10 minutes, during the first steps where I had to create a Google account and set up my phone options.
I heard rumors that 5.0 Lollipop drains the battery quickly so I downgraded to 4.4.2 KitKat with the hope that it'll fix the battery problem. I downgraded successfully without error.
I have the same problem—the interesting thing is that I didn't download more than 5 apps. I only have Skype, Facebook, Messenger, WhatsApp, Viber and Instagram. All the other apps are from the phone itself.
Whenever I go to WhatsApp to check messages or chat (or anywhere else), the battery falls 1% after 3 minutes. All of the NFC options, location options and other unnecessary options are turned off. The brightness is also on low. In 15 minutes of use I notice that the battery falls from 80% to 65% or 60%.
I have already done a factory reset twice, whilst I was downgrading to KitKat 4.4.2.
I'm a new user of a Samsung Galaxy S5. Is this normal or abnormal? What is the problem and how can I resolve it?

Not sure how that language helps anyone. Read the [help] watch the [tour] and remember to Be Nice.

I used a combination of DS battery Saver(Aggressive mode option) and Greenify(paid) to mitigate excessive battery drain. To my surprise, I managed to get a lot of juice since then. Besides, I used Better Battery Stats to find out what was causing that excessive battery drain.

My device isn't from Samsung but I had similar issues and I questioned it with troubleshooting I did. Got some answers too. You may check them, could be helpful.

i'll take a try , lol the phone is new from the store , wtf is happening to it..
Thanks for advices

Could it be a defective battery?  Have you gone back to the store to get a new battery and/or phone?  I have owned my S5 for more than a year ..I have not downloaded Lollipop, which I have heard there are some battery issues and have not encountered the problem with 4.4.4.....

who knows i installed GSM battery monitor, so it says that for:
in 1h 10m has used 6% from my battery
5,1%/h - 29m 47s active (by just cheking instagram, browsing photos, and whatsapp) nothing else , and i didnt browsing or cheking for more then 4 mins, i just enter quit.

The phone is just original from store and is just 4 days old...

"....the battery suddenly fell from 100% to 95% in just 5 to 10 minutes"

That's perfectly normal and no cause for concern. Reasons for this are well explained in this XDA post  Your battery gauge is lying to you (and it's not such a bad thing). Summarizing from this post:

As explained at Battery University, "The time at which the battery stays at [maximum charge] should be as short as possible. Prolonged high voltage promotes corrosion, especially at elevated temperatures."

so

This is why many new phones will "lose" up to 10% within a few minutes of coming off the charger. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 90%

so how do OEM's deal with this situation?

The phone manufacturers essentially have three choices:

Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
Use new charging methods and have an accurate battery gauge
Use new charging methods and have the inaccurate battery gauge

Option one has clearly fallen out of favor as it prematurely wears devices. Option two, while being honest, would most likely be met with many complaints. After all, how many people want to see their phone draining down to 90% while it is still plugged in? Option three therefore offers an odd compromise. Maybe phone companies think that users will be less likely to worry about a quick drop off the charger than they will worry about a "defective" charger that doesn't keep their phone at 100% while plugged in.

So, it's normal and have seen it happen in every phone (four of them) I owned in last four years

Try factory resetting the phone. (Ignore if already tried)
Another thing you might do is calibrate the battery. Drain out all the battery till 1% is left and put it on d original Samsung charger. Let it charge fully. Do not interrupt it while in charge. In this way the battery will calibrate itself.
My personal experience shows battery monitoring apps drain the max battery life.
Also, for once, clear all the data in the phone. I.e. images and songs so that the phone memory is not cluttered.

I think this is pretty standard. My s5 drains at about the same rate. Try turning your mobile data on only when you need it. You can also try flashing a different kernel (that works in your region) to see if that helps.

how is a kernel region specific?

I think it some can improve reception and battery life depending on your region based of memory. Maybe I read a dodgy post.

"com.whatsapp" folder repeatedly and automatically getting deleted
I have an Oppo Reno 8 Pro (Android 13).
Since switching from my Huawei phone, the folder with the received and sent images/videos in the internal storage gets cleaned automatically every 3-4 days. As a result all my received and sent media are gone.
I can use an old backup, and that restores images/videos for a while, but after a couple of days they get deleted again.
How do I fix this problem?

You might want to check the installed File Managers and Gallery apps, and whether they have a feature to auto-clean storage or media files specifically, regardless if they have been backed up or not. Usually they have a setting to ignore certain folders.

Thank you Andrew. I checked it but i dont think thats the problem. I cant find any settings like this. My brother has the same phone and not this issue :(

What does a "crossed-out globe" system icon mean?
The "crossed-out globe" icon appears and disappears randomly. Don't really know which app or state it's representing. Seems like an unavailable connection.

What does it mean?

Thanks to user Firelord, I went to System to check which version of Android and CalyxOS I do have. I stumbled over the "Statusbar icons" area. There you can enable/disable notification icons. The crossed-out globe stays for Firewall. I assume, that a firewall match (block) shows this icon.

How to get the Wifi password from a previously connected network?
I have a Xiomi 10T Pro running Android 11. There is a WiFi whose password I want to know. My device is registered with that WiFi so I have no problem connecting to it BTW.
I am aware that I can choose to share my Wifi credentials from Settings. They are shared in the form of a QR code. That said, in my device I can share credentials for only those Wifi networks to which my device is connected to in real time.
This would not have been a problem except that the Wifi whose password I want to extract is hosted on a router that is located in an another country. So getting access to that real time Wifi is no longer feasible. My device is not rooted either.
So what can I do get the credentials for that Wifi without connecting to it?

How to check if Status bar is expanded?
I would like to determine, using ADB, whether Status bar is expanded/collapsed. I'm just looking for a way to check whether it's expanded or not, not what caused it to expand/collapse.
I know that there is cmd statusbar that can either expand or collapse the Status bar but I couldn't find a way to check its current state.
What I've tried so far:

comparing the output of dumpsys window windows| sed -n '/Window .*StatusBar.*:/,/Window .*:/p'
comparing  the output of dumpsys statusbar -> mDisableRecords.size is the most promising key, but I can't understand what exactly its value mean.

Can this check be done through any other command or am I missing something?

grep StatusBarWindowController from logcat. Whatever last entry you would grep will tell you whether expanded flag is set to True or False.

How to fix internal sd mounting error?
I have a T-Mobile Vibrant i9000 SGH-T959 variant phone,
phone suddenly stops working error message:
movinand open fail

 E:Can't mount /dev/block/mmcblk0p1 (or
 /dev/block/mmcblk0) (No such file or
 directory) E:copy_dbdata_media:Can't
 mount SDCARD: copy default media
 content failed

Is there anything to fix this ?
I tried various odin roms, only one working: Eugene_2E_JK2_Froyo.tar.md5
phone booting up but, settings → sdcard and phone storage says: unavailable

It does sound like your internal storage has been corrupted, but I don't know if I would try to format it via your PC. this is not actually an "SDCard", it is the internal storage on the device (which is a SGH-T959, not an I9000).
I would revert back to STOCK ROM using ODIN and return the phone under warranty. If you are already having issue with the internal storage, I would want a new device.
Now I guess you could try and format it via your pc (I dont know if you can even access it when its mounted via USB because I never mount it) but I, personally, would not, I would get a new device.
For reference, the i9000 is the international version of the Galaxy S phones. None of the US carriers sell the i9000. They sell different versions of the the Galaxy S phones. For example, the T-Mobile Vibrant is the SGH-T959, The Verzion Fascinate is SCH-i500, the AT&T Captivate is SGH-I897. While they are ALL Galaxy S phones, they are all also different devices. They have different hardware, like some have a front facing camera, led flash, 4 buttons, etc.

is there way to format internal sd? phone options unclickable. adb format possible ? and there is no way to send warranty, I'm in different country

I think you can format the sdcard in ODIN... been a while since I flashed with ODIN though, so I could be wrong.

Check the "Re-Partition" option in ODIN.

already tryed, result same :(

It definitely sounds like there is something seriously wrong with your internal storage. I would see if there is any way you can send it in under warrenty

I just had this same issue on my Droid 3 after I installed a Deoxded Stock ROM.  I was able to install Titanium Backup, but could never access my backup directory.
Ended up that I never disconnected my phone from my PC and while connected it would not allow bidirectional access (from PC and from phone).  Disconnected it from my PC and volia, my Internal SD Storage showed up.

On my I9000 (galaxy S) this just means that something has changed the file-system within the phone like ext2>ext4 and the current kernel doesn't support it..
Normally happens when flashing custom roms without checking the kernel requirements.... like I did :-(
The only way round it is to reflash using odin with a 512.pit file and make sure you select re-partition..

I think your internal SDCARD was corrupted, you can try connecting the device to the PC in external disk mode and try formatting the sd card from windows.

nope, not work. says: insert disk and try again

How to share Android "Reverse-tethered" internet via Android WiFi?
Before going into main question, we do know that :

we can do Reverse Tethering from PC into android (http://forum.xda-developers.com/showthread.php?t=1371345)
And we can share current phone internet connection via Portable WiFi hotspot (or similar apps in Google Play)

Now the question is :
"Is there a way to share the reverse-tethered internet (as we known connected via usb0 interface) via "Android WiFi Hotspot?"
To make it easier, here's the schema:

Schema of my setup (click image for larger variant)
*Additional Notes :

Actually I don't give a limit which version of the Android (so if it's just compatible in higher version e.g. 4.2, it's okay for me), but I prefer it works on 2.3.x (Gingerbread)
Some explanations of how to make APN (Infrastructure Mode) on Android (just like Wireless Router/[netsh wlan hostednetwork] on Windows 7/8) might be really helpful too.
And also some explanations about how to masquerade (internet sharing) between two interfaces in Android. (such as ICS in Windows or Masquerade/iptables thingy in Linux-based)

possible duplicate of How to set up reverse tethering over USB?

@t0mm13b No. The OP doesn't want to know how to set up reverse tether, but how to share that connection to other devices.

yeah, that's quite different that just reverse tether.. it's more advanced which, after you tether, you do "masquerade" sharing from usb0 into wlan0 and broadcast that as wifi hotspot. i understand that mistake that pretty "similar". please let LO this one. thanks in advance.

Btw: You might wish to take a look at Can we use an Android phone as a Wi-Fi repeater? and see how it applies to your case. Don't forget to let us know here then :)

Excuse me, would you please tell me where to write and execute this script to allow wifi tethering while reverse tethering from usb? And please, is it a one way process or is it temporal?

it's temporal. it breaks if any of interface down (offline) or restarted.
write this script via text editor and save it as .sh, execute it via terminal (emulator).

I able to access PC internet in android mobile using "AndroidTool.exe" tool now can anyone tell me what is next step to share the internet using wifi-HotSpot to other devices. above command tried still no success.

I made a tool special for that use case: tetherspot
This script simplifies reverse USB tethering with WiFi hotspot on non-rooted Android devices
The main idea is to use

Gnirehtet on PC to start reverse USB tethering via VPN and adb
Proxy server on Android to route WiFi hotspot traffic to VPN

Galaxy s2 screen turns on by itself
I'm Running a Galaxy S2, with the AOKP milestone rom (JellyBean). Occasionally, the screen will turn on by itself (even when no user apps run in the background) after being turned off, light up, turn off and on again, it won't remained off for a long period of time. Needless to say it's annoying and battery draining.
Rebooting doesn't always help, some times it goes away only to return a day or 2 later. Has anyone else encountered this issue with AOKP or other CyanogenMod based roms, and if so how you did addressed this? how should I fix this or disable this?

My GF's Galaxy Nexus was having the same problem, though it had the additional problem that it didn't want to charge. I did a factory reset (after trying various settings), which seems to have solved the problem for now. However, I'm not sure if its exactly the same problem.

I did a factory reset before flashing, doubt another one will help, I just don't want to go through the mess of backing and restoring only to have this happen again.
EDIT: also as far as I know, it may also be a fluke with the device mishandling things

But you installed a bunch of stuff after flashing right? Can't those things and/or any setting changes be responsible?

Something might run a service in background which, from time to time, requests a full wakelock. That would force the screen on for the time the wakelock is held. You could use BetterBatteryStats or Wakelock Detector to find out if that's the case -- which might even reveal the culprit then.

Wakelock Detector marked the facebook app as one source, uninstalled it and the wakelocks still continue (the googlesphere also pointed that other users also had wakelocks from the FB app!!), either it didn't work or there is another source.

I eventually found the cause of the issue to be in the screen-off animations in the display settings. I had the 'Electron Beam' animation selected, I disabled the screen off animation and the wake-locks stopped.

Its the small things!! +1 for figuring it out

Cannot screen mirror youtube to TV
I am using a Samsung Galaxy Tab 3 10.1 with Android 4.4.2 and a Samsung UE48H6270SS.
I can screen mirror my Music and also Media using the Samsung Smart View App but I can't do it with YouTube. There is an option in the YouTube-settings to "pair" a device with a TV, but that requires the TV to install the YouTube-App on the TV which I don't want to install. (Or anything else related to SmartTV). Is there any alternative to the YouTube app or another solution?

AFAIK, there is no alternative to the YouTube app. However do you expect your TV to decode the video by YouTube. Also: Isn't the YouTube app preinstalled on Samsung Smart TVs? I have one and it came with some preinstalled apps, that are working like a charm.

When using the HTC Sense stock browser I can press play, go to
menu → ... → settings → site specific settings → back out until l I arrive at the site again
Only then the music will start playing.
If I activate the key lock or take the focus away in any other way, the sound will stop.
When using Opera Mobile I can't seem to get the sound to work at all.
Looking at the site's source the streaming is done with Javascript (mootools).
On my desktop I don't get any javascript errors and the site works perfectly fine.
Can anybody tell me why I have to jump through such hoops with the stock browser to get the sound going, how I can have the browser keep playing in the background or with the key lock on or why the sound doesn't seem to work in the otherwise nice Opera Mobile?

I don't know if it's even possible to have the media stream continue when the browser loses focus. Youtube videos, for example, do the same thing (stop playing when the browser loses focus).

eldarerathis is right.  This is to prevent page ads fron draining your battery when you're not using the phone (for example), page execution is stopped.

I understand the reason, but that's also an argument against web apps vs native apps.

You should take it up with Google ;)

This is to prevent page ads fron draining your battery when you're not using the phone (for example), page execution is stopped.
As for Opera, I believe they have their own JavaScript engine, so maybe it's not standards-compliant.  Or maybe it doesn't interface well with the Android sound system.  Or maybe the page's JavaScript isn't standards-compliant.

How to Downgrade Android on Huawei
I have a Huawei CE0682, which by default came with Android 5. I upgraded to Android 7, but the mobile internet has become very slow.
How can I downgrade my phone back to Android 5?

CE0682 is not an actual model number (you're probably looking at the CE certification label). Also, unfortunately most if not all manufacturers prohibit downgrading strictly.

You can try to just install the 5.0 rom on your recovery. If that doesn't work you need to install twrp recovery. You may find them from xda developers website.

Tried many ways to root my Telenor Infinity E
I have been trying to root my phone for two weeks using various exploits but till now all in vain. The devices isn't international so its not famous and I couldn't find any recovery, custom root or rooting method for it on the internat, although I found stock ROM which saved my phone several times when I soft bricked it.
My Device:
Model: Telenor Infinity E
Build: TELENOR_INFINITY-E_L100
AOS: version 6 Marshmallow
RAM: 1 GB
Chipset: MediaTek MT6735M
Kernel: 3.18.19 Aug 22, 2016
Android Security Patch level: July 5, 2016
Stock recovery: Having no menu

Bootloader: Unlocked
Methods Tried:

Tried famous desktop applications: OneClickRoot, KingRoot, KingoRoot, RootGenius, iRoot etc. (All failed)
Tried flashing TWRP of similar device using SP Flash tool. (Result: Boot Loop)
Tried porting TWRP recovery using stock recovery and Android Kitchen. (Result: Auto reverted back or Soft Bricked)
Tried injecting su, supersu in system.img using android kitchen and flashed. (Result: Soft Bricked)
Tried Many Repack tools like simg2img/make_ext4 binaries, similar tools/guides to repack system.img. (Result: Soft Bricked)
Modified ro.secure=0 and ro.adb.secure=0 in default.prop and re-flashed boot.img (success, but no root)
Used dirtycow exploit scripts got root shell but still no permissions to modify /system.
Patched adbd in boot.img using adb insecure app's assets and got 'adb root' access. (still can't modify /system or remount in rw)
Found SELinux's getenforce=1 and neither could disable it by command setenfore=0 or echo 0 > /sys/fs/selinux/enforce nor found any method except making a custom build of kernel (which is not feasible for me).

Can someone help me to Root this device or tell me if there is anything else I can try?

scrcpy access problem with Linux
I have 2 Android devices: a tablet from Denver and a cell phone from Xiaomi (Redmi 9C), I installed scrcpy on my MX Linux pc, I have no problem to access tablet through scrcpy, but when I tried with Redmi 9C, I can only see it, the mouse does not work, did I miss some settings? The developer option is enabled (is there any other options inside developer options that I need to change/enable? I only enabled developer options).
note:

I've tried enable file transfer when plugin the USB cable, seems to make no difference and adb device command can see this device.
adb version 1.0.41

Looking at the issues page of scrcpy it seems that there are quite a few devices which have problems with scrcpy.

This is the solution given by alecxs.
Add Mi account and enable USB debugging (Security settings) option under Developer options.

What does a small "two white rings inside orange circle" icon mean on an app icon?
I am using a Samsung Galaxy S21 Ultra. Why do I have some apps doubled up such as Settings, Chrome, Android System Web View, and Google Play Services?  They have a small orange icon with two circles.

As mentioned by Andrew, the newer models support Dual Apps.  On my system I can see other apps such as:

Chrome
Whatsapp

If you search for Dual in Settings, you will see the option Dual Messenger that allows you to use a second copy of select social apps with a second account.

If you press it, you can see the following, where you can select which apps you want to use.  And you can use a separate contacts list for these.

To disable this:

click on the three dot menu at top right;
press Delete all my data.

Is it possible to recover apks after a wipe?
Today, I unlocked the bootloader of my old Oneplus One, which wiped the data partition of my phone. I had a backup made with adb backup -all but I discovered only after the procedure that apks were not included.
This phone had some apps that I had installed which are not found around anymore. I want to keep them for nostalgia sake. So, I'm wondering if there's some way to recover apks from a wiped phone (just like you can do a disk recovery on a PC using tools such as Recuva). I tried looking on the internet but I found tools that either recover only data but not apks or are pure scams.

If Oneplus  did their job correctly a bootloader unlock wipe erases the user data encryption key and thus makes all user data including APKs unrecoverable.

I see, thanks for the info!

@Robert OnePlus One was released in 2014 with Android 4.4 (upgradeable up to Android 6). As far as my experience goes with OnePlus One (Android 4.4 - 5.0) there was no default encryption of data partition. So if OP checks the current status of encryption they may realize that data recovery is still possible to some extent.

@Firelord I used "adb shell getprop ro.crypto.state" and it returned unencrypted. I'm confident I never activated encryption on this phone before wiping

@valepu in that case unless if you enabled encryption long time ago and forgot about it I'd assume that before you unlocked bootloader your data partition was unecrypted too. Which implies data recovery is possible to some extent.

Yes I'm sure I never activated encryption on this phone. The problem is how to do data recovery

For data recovery you can try reading up this resource: https://android.stackexchange.com/a/208114/96277

oh i see that's clever. Create an image with dd and then use typical PC data recovery tools, i shall try that!

How to enforce no eye comfort shield for certain apps?
I have a Samsung Galaxy A40 SM-A405FN/DS, set up in German. It has a functionality called "Eye comfort shield" to make colors less blue and warmer.

I like my screen with eye comfort shield on always, as it helps me to not be constantly swallowed in the virtual world and stay more grounded in the real world.
But I recently downloaded a great game (I Love Hue, for the curious) which heavily relies on hue distinctions. The eye comfort shield makes it all the harder.
Is there a way to specify that eye comfort should be off for specific apps ?
For those who don't know:  eye comfort shield removes some of the blue component of the color of every pixel on the screen, so that everything appears warmer. Blue light, which in the real world we get almost only from the sky during the day, acts a stimulus to stay awake (and then we feel naturally tired in the evening). Too much blue light from a phone screen is supposed to keep the user awake and hinder falling asleep.
One possible source.
This feature might be known as Night mode or Dark mode or Night Light in non-Samsung devices.
Images :

EDIT : @Firelord My attempts with Tasker :

When Eye Comfort Shield (ECS) is enabled could you try running this adb command adb shell settings put system blue_light_filter 0 and see if it disables ECS or not.

Yes it works, including while having the app open. I can't wait to see what you're suggesting with that !

Setup Tasker app (trial version here). Within Tasker setup Profile: Application -> select the apps where you want ECS to be turned off; create/assign a task having this action: Setting -> Custom Setting -> Type: System, Name: blue_light_filter, Value: 0. Leave rest of the entries as is. Save the task, enable ECS and now try opening one of the target apps to see if ECS turns off or not.

Excellent ! But no results yet ... see my screenshots in edit.

On that second screenshot, there is Play (rightward arrow) button on the bottom left. Upon pressing that Play button does ECS turns off or does Tasker report some error?

A notification appears : "Can't modify settings : Please click here to install the 'Tasker Settings' app to change the 'blue_light_filter' setting". It also independently started telling me this when opening the app (so somehow I hadn't correctly applied the rule or whatever).

And sadly when I click on the notification, it takes me to the page of the Tasker Settings app on Google Play, where it says : This app isn't available for your device because it was made for an older version of Android."

Re: Tasker Settings app, try downloading from its GitHub repo.

Yup works. It keeps telling me that it might not work properly at all because it's meant for an older Android version but okay. Now the whole setup works : a few seconds after opening my app I get the ECS off. How about part 2 now, turning it back on when I quit this app or switch app ?

Found how to do this. You can add an context like for the other task, except you press the "Invert" button and then context is "Not " and it does what you think it does.

If you post a summary I will mark it as the answer.

@Charles I think you're in a position to provide a working answer with nice screenshots and gotchas that you encountered. Go ahead. :)

That does not take into account my legendary sloth.

Also, the trigger seems to go through every time in reasonable time (and in fact the ECS button shows that its off) BUT the EFFECT of ECS is often still present ! And vice-versa. I think it is either a bug in Android, a delay (my phone can be slow), or we are missing a "refresh" sort of command or something.

How bypass ZTE factory reset protection
I did a factory data reset on phone and it still wants the last synced Google account.
I found phone and would like to bypass factory reset protection, how do I do it?

OK, can't guarantee this will work but I've had success in the past using this method.
First complete factory reset with no Wi-Fi connection. Don't enter ANY information or password, knock, pattern, anything..
Next, turn off phone, then hold power and vol up till phone cycles on.
Again, ENTER NO INFORMATION. Now, power off and back on normally with no Wi-Fi.
Disable auto sync and connect your new Google account..
Voilà

Updated Galaxy s3 and SD isn't recognized
I recently updated the software on my phone and it works great!! It's lollipop 5.1.1 , the problem is that the phone doesn't recognize the sd card anymore and my computer doesn't recognize as a removable drive anymore. I just want to know with that being the problem is there a way to downgrade back the the old software? and how if I cant use the sd card?

I also have a Galaxy S3 and it has "eaten" two SD cards! The phone won't recognize the cards anymore and my computer doesn't recognize them either. Did you find any solution for this or are the cards just fried?

There could be simple fixes that will allow you to keep your upgrade. With each new "flavor" of Android new APIs are released with relation to enhancements to the OS. Have you tried a brand new SD card? or backup and format for the current one?  Also a reinstall of the USB drivers may help. I hope you backed up your previous stock ROM because if not you will need to find one online(if possible). It will help if your device is rooted.  Good Luck!

There is lack of info from OP, but reinstalling drivers wouldn't make an SD card popup in my computer as removable drive since 4.4+ and 5.0+ devices doesn't have "USB Mass storage" support.

I was under the impression that the host device (computer) was not recognizing the tablet. Suggested the reinstall of drivers as maybe a way to get to MTP due to the upgrade.

Need to delete data from dead phone?
I have Samsung Galaxy phone. Now its dead. I tried lots of combinations and now I'm going to send it to India. In India it will get repaired but I don't want anybody to get the data, messages or media files which is in internal memory. But as its not charging, I can't delete data directly. How can I delete media files specially from internal phone memory from my dead phone?

What do you mean by dead...Not Charging Are you able to connect it to your System?

If you can charge a little  or arrange a new battry I guess you can do it by wiping data in recovery mode.

To do so hold the volume up, home button and power button simultaneously.
Once you are in Recovery Mode Scroll to wipe data/factory reset by pressing the Volume down button.

THATS IT.

Had a look around for you, I've never imagined it to be possible to retrieve data from a dead phone without external storage inside the phone i.e SD Card, then I stumbled across this article. A user commented something which i think you may find useful. I take no credit for this answer, try at your own peril.

WARNING! - Refurbished only means you will get a working phone back.
Even if they guarantee to return it with your data intact, be VERY
  CAREFUL! they are just telephone call handlers and do not know for
  sure what will happen, also people do not tick all the correct boxes
  and others do not look at all the boxes, so you could loose out those
  ways!
I am very surprised that there is no information on this subject.
It must have been an issue for 1000's of people over the past few
  years.
My problem is that "back up has stopped", would not re-install, and I
  could not find out why (it said memory, but there was loads free -
  since found it was talking about Dalvik).
Over the weeks I built up a collection of useful information and
  photos which I do not want to loose.
I am assuming yours is an Android phone, but even if it's a Windows
  phone, the principle is still probably the same.
It appears to be possible to recover files from the internal memory of
  a dead phone using a PC, free software and USB cable.
The principle is start the Flashing process, BUT do not Flash the
  phone, because I can not be sure it would not destroy your data /
  files.
When at the stage to be able to Flash the phone, effectively your PC
  thinks it is communicating have a "USB memory device".
This is achieved by removing the phones USB driver and substituting
  another driver (to enable the Flashing process).
I've not had the time to spend on it that I need.
I will come back when I do finish ...
BUT do not wait for me, there seems to be too many things going wrong,
  and the most important get done first. Which is why I have things
  waiting for over 1 year now.
One problem I have is that Windows keeps throwing out the
  "substitution USB driver" and replacing it with the original phone USB
  driver.
Windows thinks the phones driver is more suitable, so automatically
  re-installs it.
I know the issue, I've had it several times previously with the
  "unknown device USB driver" (a crash causes the driver change). I just
  need to find the "Windows stored back up driver", delete it, then
  Windows will happily accept the "substitution driver".
Ahhh, the joys of owning a MS Windows computer :-(
Some usefull software names :-
USB VCOM Driver
Windows drivers - A25_USB_VCOM_Drivers
usbdeview_droidtricks
Some useful search terms :-
brick
unbrick
flash rom
SP Flash Tool exe v3 (not to use, but the process' before is what's
  wanted).
Searches with search engines (Google, Yahoo, etc.), also You Tube (I
  could only find Flashing, but as previously, it's the process up to
  the "Flashing point" that you are interested in).
Sorry it's unfinished information, but at least it gives you hope and
  some where to start.
Data Recovery firms will be able to recovery the data / files and some
  are open to "please help, I'm skint ...", by reducing their prices to
  a poor private person, but they will not do it for free.
So good luck to all of us.

And this gentlemen in the comments of said post found a company willing to retrieve information from a dead phone, this could be worth a shot prior to sending it to India.

Hi Maria, sorry for the late response. They are called http://iekspert.dk/ or > iexpert.dk - try and write to them.

Just have a look and see what you find.

how do I get my google play store to start working for my Samsung galaxy exhibit (T559)?
I was going through my app settings and accidentally uninstalled all my updates on my Google play store, it lets me pull up the old version but it will close out and say it has stopped working . I have tried to fix it but it won't work.

You can download the apk version from this link:
Google Play store 5.5.12
And install it after you downloaded it.
You might change the security settings of your phone to download apps from other sources.

Huawei mobile File Transfer to my computer doesnot work
I used to transfer files but now I can't. The USB cable transfers from another Huawei, but from my Huawei mobile it doesn't. I turned debug on. Still my computer does not identify it.

Did you installed the drivers on your computer. Did you manage to change the mode in which phone acts when linked to computer (USB storage , MTP, PTP)?

Did you try to install the drivers?
If you didn't do this you should install Samsung Adb drivers, it might say Samsung, but it's for all devices. First install it from this link:
(Samsung) Adb drivers
After that:

Reboot your PC.
After the reboot press  + R and type devmgmt.msc.
Find the phone, do right click on it →  Properties →  Update drivers.
Select Browse my computer for drivers.
Select Let me pick a driver from a list of installed drivers.
Select "Adb drivers" (it might be called something different).
Select Samsung Android Adb interface.
Select Yes to continue (if you get a warning)

You're all set to copy.

Convert number in call log to Gmail Contact
When I get a call from some number I know I want to convert it into a contact. I expected to be able to do something like long press, then type the contact name, but when I long press and select add to contacts, it just kind of disappears into my contact list.
I'm sure everyone does this all the time, and so I am missing a really obvious way, but perhaps someone can enlighten me how to do this easily.
[edit]
Samsung Galaxy S, with Samsung overlay on Android 2.2, TMobile

Both Dialer and Contacts apps can vary per phone model due to Android OS version, as well as manufacturer or carrier overlay.
Usually though, in the call log when you tap on the new number it gives you an "Add to contacts" option.  At that point it brings up a list of all contacts, so that you can add this number to an existing contact. However, there should also be a button to create a new contact, which is probably what you're overlooking.

Ah, so I click the add contacts button and it does carry the number through. That is indeed what I was missing. Thanks.

delete operation are extremely slow
For some reason, moving files from my Nexus 5X to my PC takes huge amounts of time.
The copy "part" of the move operation is pretty much as fast as on any other Android device I've used (I can see the files actually being successfully created at the destination folder on my PC), but then, when the deletion "part" takes place (my indication is that all the files have been successfully copied and the progress bar reaches almost the end) -- the Windows File Explorer instance which handles the source folder just hangs, for a really long time.
For instance, when performing a move operation of 50 images, with an average size of 4MB each -- the copy "part" takes a few seconds, while the deletion "part" takes more than 5 minutes.
My question is: are there any specific tools, using which I can pinpoint the problem, or see a detailed log/real-time statistics regarding the deletion operation?
I'd appreciate any suggestions regarding the situation, which is obviously really problematic.
I've tried this on multiple laptops.
An important detail regarding my Android OS -- I have more than 29,000 images on my device (my entire WhatsApp history, since 2011). Maybe it has such impact on the file system?
I've attached a screenshot of the status bar and the "not responding" File Explorer window, during the deletion "part" of the move operation.

Have you tired to create some free space on the phone? I have observed similar things when device is  pretty full

Also on your laptop clearing recycle bin helps

@beeshyams currently I have 1GB of free space on my device. Anyway, it's a loop - I can't really make lots of free space, due to the fact that I can't move my camera photos to my PC.. It just takes too much time. Regarding your second comment - I've tried this on multiple laptops. The problem always recreates.

Interesting. Let's hope to have a definitive solution +1

First of all, what happens when you copy/move files inside phone with file manager without PC interaction? I had similar problem when my sd card went crazy and slowed down r/w speeds, so moving anything was pain in the ass. You can try app called "A1 SD benchmark" it should be able to test internal storage speeds so you can check is there anything unusuall. To me this sounds like hardware issue, and maybe just maybe android went crazy and factory reset will resolve a problem l, but I wouldn't recommend that due you can't backup your data.

@golosovsky Is this behavior experienced even when copying a single file from the phone to the computer?

@DeathMaskSalesman one of the questions I asked is here is a suggestion for a tool/utility to measure this type of things.

@ЈеднорукиКрстивоје thanks for the suggestion, I'll perform this test. BTW, it's an internal SD card.

Yeah I know that, I said similar case not the same. Maybe I'm not even close, but you should check.

RCA Tablet Root problems!
I have an RCA Tablet with Android 6.0.1 and no matter what I try I cannot unlock my root bootloader. When I reboot into the bootloader it just takes me to the main tablet stuff. In other words the screen with the laying down Android robot will not come up. I've used adb and fastboot but the fastboot wont recognize my tablet and adb does. I've tried a lot of one click rooters, and nothing!
Is there any way I can manually re-root my RCA Tablet through the terminal or maybe even get the fastboot to work?
UPDATE: Can you tell me how to install SU binary on to my tablet?

I'm not sure if this will help or not but on my RCA Galileo running 6.0 in the Developer options menu there is switch called "OEM unlocking". That should allow you to unlock the bootloader. I haven't actually tried it so I don't know for sure.

@bashBedlam Thank you very much, but I have been able to unlock OEM and it didn't really do anything. I have the voyager 3 but its running Android 6.0

Depending on what RCA tablet model you have, the answer will be the same; try googling: How to Install CWM/TWRP on your RCA tablet model. Follow chat for more comments here. [Edited by Moderator Firelord]

I'm afraid this is not possible, yet. I also have the Voyager III, and there is no way to root this device right now.

Android Phone connected as ttyUSB device
I need to connect my Android phone or tablet to my Ubuntu 16.04 and use smstools or minicom for reciving/sending sms for further data processing. In all tutorials about minicon or smstools they discribe connected Android device as ttyUSB*, whereas in my case every time I connect my Samsung S6 (stock Android 6.0.1) or Samsung Tab S2 device (stock Android 6.0.1) it shows up in dev directory as libmtp-1-2. not as tty device.
When I point in minicon to /dev/libmtp nothing is happening.
Are my devices incompatible to run such software or do I need to root my devices to deal with stock system limitations?
Thanks in advanced

Because Android doesn't talk on USB that way anymore... Not for many years, your tutorials are out-dated.

How to remove Google account on Chrome?
My boyfriend needed to use my phone to access his email. Since logging in his account remains the default user whenever I open Chrome and Google search. I have tried deleting my device on his account in under active devices. I have tried going into Chrome settings but there is no option to remove the account!

Go to chrome>settings tap on account then sign out. Does that works?

Go to settings>App>Chrome>storage, and clear cache and data(clear all). Open Chrome again, step 1. Accept and continue to start, 2. enable/disable data saver, 3. ask about Google account, to skip, select 'not now'.

Are you sure that your boyfriend's account is opened only in chrome ?
Well i think it's not.
The problem is not with the chrome if i am getting your problem.
Here the person adds his account to your Google Services and your device is currently using it as its primary account. So, it is auto logging in as default account in chrome.
If you want to check:
Open Gmail app look for the account signed in already by touching 3 lines on the upper left of the screen, there must be showing your bfs account.
So now, you have to remove this account from your device. Follow these steps:

Open Settings-Account-Google
Now click the account you want to remove and touch 3 dots on the upper right corner of the screen and choose remove account.

It's done.
However, what you have did by removing your device from his 'my activities' tab.
This will only unlink your device from his Google account that means if you will try to sign in it may need to go through verification for signing in next time. As your device is now unknown/new for this particular Google account.

Just hit "log out" and it'll log out of all of them. Then when you hover over it, it will finally have the "remove" option.

If you want to remove his account from the phone  (Android), follow this steps:

Go to Settings → Account → Google
Then tap on his E-mail/ID , you can see the more menu on right top corner, tap on it
It will show two options Sync now and Remove account
Tap on Remove account option
Done

If you have to remove account from chrome browser then open the browser and click on settings, then there is account on top tap on it, it will take you to next page from there you can remove, add or change account.
Second way is Goto Settings>Scroll down to Accounts (Portion)>Tap on Google, there you will see a settings icon(3 vertical dots icon) on top right corner click on that and tap on remove account.
Third way is Goto Settings>Apps>Chrome>Tap on Manage space/Storage>And then clear data from there. Hope it works....

In the Chrome browser...If it takes you to your Gmail account as saying signed in by your email id ...don't worry press the upper left button which have three horizontal lines ..It will show your email id in upper corner.  click on it. Then it will go to "choose google account " page sign out from your account . After signing out if you want to remove your account you can. remove your account and add another account.

create-user "Error: couldn't create User"
I tried creating multiple users on my Android TV dongle (based on RK3188 board). It should work, it's Android 4.4.2, but it returns an error:
root@rk3188:/ # pm create-user username
Error: couldn't create User.

And at the same time:
root@rk3188:/ # getprop fw.max_users
4
root@rk3188:/ # pm get-max-users
Maximum supported users: 1

You should edit your build.prop and add the following lines:
fw.max_users=2 #in case you want a maximum of 2 users
fw.show_multiuserui=1 # to show Users menu in settings
Save and reboot. You will then be able to add users

But according to the question, fw.max_users is already more than 2. How will decreasing it solve the problem?

It is not about decreasing the number of users(the 2 is just an example), but more about modifying his build.prop mainly the fw.show_multiuserui part

Unfortunately this does not work. The problem still is as described above from the point of view of CLI. I didn't know about the fw.show_multiuserui settings, this is a nice part, but it still doesn't work, no Users menu is visible in settings after setting it to 1 and rebooting. I suppose the problem is in the way the build has been done and its related to software components that cannot be changed in a compiled image as it's something missing, not just disabled...

May be my answer should be removed. According to this article AndroidTV News, multi-user support isn't available on Android TVs.

How do I undo "always show pictures from this sender" on Android gmail?
I accidentally clicked 'Always Display Images from This Sender' ('Always show pictures from this sender' in 2020) and was wondering if there's a way to undo this setting in Android gmail.
It's straightforward to undo on web Gmail, but not the same with Android (that I know of). Any help is appreciated!

In the Android Gmail app,
From the main inbox or inside any email: Bring up the Menu > Settings > General Settings. Now click the Menu button again to bring up sub-menu of options > Clear picture approvals.
WARNING: This clears ALL your approved sender settings, I believe there is no option to revoke by individual email senders.

Thanks! This did it for me. Just to be clear, once on the General settings page, click the three vertical dots(icon) on the top right corner to bring up a popup menu that has the "Clear picture approvals" option. It will display a confirmation prompt that says "Stop displaying inline images from senders you previously allowed." with a CANCEL or CLEAR option.

I needed to clear this setting for a single email address. I followed these steps:

Open Gmail (mail.google.com) in a web browser
Open an email from the sender which has an image in it
In the top left of the email it will have the sender's name and below that "to me" with a little down arrow next to it
Click the little down arrow and then click Don't display from now on

This seems to be outdated and isn't available for me. See https://webapps.stackexchange.com/questions/103469/undo-always-display-images-from-this-sender#comment126880_103470

@Ryan - still works for me. Make sure the email has an image in it

@RayfenWindspear This is the answer that I needed, but it's technically not correct because OP asked specifically about Android.

Worked for me 2021

A perfect and illustrative answer.  Worked for me, too.  Thank you!

If you do it from from gmail you can do it on a by sender basis. Here are the instructions: https://productforums.google.com/forum/#!topic/gmail/v0rJQjdR-Pc

click show details then click Images from this sender are always
  displayed. Don't display from now on.
NOTE YOU WILL ONLY SEE THAT OPTION IF THERE ARE EXTERNALLY LINKED
  IMAGES - NOT IF THERE ARE INSERTED OR ATTACHED IMAGES

Please include the instructions in your post, if the link stops working this will be useless.

Hi, I don't see that option. I went to email details, it only shows, from, to, enctryption, etc.. but no option to not display images.. Any suggestion?

@Rafael I found these instructions clearer: http://www.prowebguru.com/2015/04/how-to-disable-always-display-images-from-in-gmail/#.WKcCelfR37g

This solution no longer works.

I agree with @LS This seems to be outdated and isn't available for me. See https://webapps.stackexchange.com/questions/103469/undo-always-display-images-from-this-sender#comment126880_103470

In 2020 there is still a working solution to the problem of having accidentally chosen "Always display pictures from this sender" in the Android Gmail app (how I miss Inbox).
Gmail app > Settings > General Settings > Triple Dot Menu > Clear Picture Approvals.
PS I'm adding my answer here even though it's a partial duplicate of another (with lots of up votes). I ignored the other answer since it referenced a specific version of Gmail from 2013 figuring that it was no longer valid. Hopefully this answer will help others like me who skip the other answer.
FYI If all else fails there is a "nuclear option":
Clear the Gmail app's storage

Open System Settings app on Android.
Find the Gmail app details where you can clear cache and storage (Settings > Apps and Notifications > See all applications > Gmail on Android 10).
Choose "Clear storage".

Your stored accounts should persist but the unintended consequence of this action is that all your Gmail settings customizations like more sensible swipe behaviors will be lost. You have to ask yourself if the cure is worse than the disease.

Samsung Galaxy S Firmware Update
I'm experiencing trouble with the 2.1 to 2.2 update. It looks like this advice doesn't work for me as I have no Software Update button. I also tried this advice but it seems that I'm not able to put it in the download mode (it just doesn't apper). Can someone help me with the issue?
I also have next message in KIES:

As to KIES:

My firmware version is 2.1-update1.

You have installed the latest version of KIES , haven't you ? I had issues with previous versions, but updating to the latest version on my Windows 7 pc allowed me to upgrade to the latest version (2.2.1).

Check out edit.

@den-avamaniac: Ok, that should do it , although I have version 2.0.0.11032_12.

My answer on that other question wasn't quite right -- I have a US variant on the Galaxy S, and the process to get into download mode isn't exactly the same.  I'll update that answer shortly, in the meantime here are the Odin instructions:
Go to this XDA thread and download the newest firmware for your region.  Download Odin for Windows (search for "Heimdall" if you are on Linux).  Then do the following:

Put your phone into Download mode

Remove the battery
Hold VolumeDown plus the Home key plus Power.  While holding,

Reinsert the battery.
Release the Power button, still holding the others, about 1 second after the white "GT-I9000" text appears.
After a few seconds a yellow triangle with an android in it should appear, this is Download Mode.  If it doesn't, try this again while holding Power the whole time.

Start up Odin.
Attach the phone to your PC via USB so that Odin recognizes it.
Load the .zip file you downloaded (the ROM/firmware) into the PDA field of Odin.
Load the 512 .pit file into the PIT field of Odin.
Check "Re-partition".
Hit Start.  Odin will tell you when it's done; if it fails, reboot your phone and try again.  (This happens occasionally).

Note that if you need to back anything up, you should do that beforehand and save the backup to your PC, since everything (except probably the external SD card) will be wiped on the phone.  Also note that you do this at your own risk; Odin is very powerful and misusing it can damage your phone.  I've used it dozens of times myself safely.

What's odin official site?

There is no official site for Odin, it's an internal Samsung tool that has been leaked.  If you're worried about the download, I have downloaded it from the location I linked and used it, with no problems.

What actually worries me is that most people have the Update Software button. And that I shouldn't be going through all this just to get it updated. :)

Understandable.  One would think that Kies would offer you the update, since it's detecting that you don't have 2.2 yet.

Great, the download mode works. That's a real progress. :)

What are the know/possible consequences of inappropriate Odin usage?

The main problem is if you flash a bad ROM (corrupt download or firmware for the wrong device) it can brick your phone.  In most cases when something goes wrong you can still get the phone into Download mode even if it won't boot, and Odin can be used to undo the damage.  I've used Odin lots without problems, but if you're unsure about anything do feel free to ask.

Funny, but it seems that the problem is actually in the network segment, from which I tried to update the system. It's super secure and has extremely filterable traffic, and it allows only certain range of ports to be used. And it looks like Sumsung is trying to be smart and use certain own security. :) Though this way should be working. Thanx.
