App doesn't access GPS location directly
There's a strange situation with Citymapper, where it doesn't access GPS location directly, but it does if a different app is accessing location at the same time. This hasn't always been the case, but I'm not sure exactly when it started (so, can't say if it's because of a certain update etc.).
Problem details:

I'm using Citymapper 6.23 on LineageOS 14.1.
The Location permission is for Citymapper is turned on
"Location mode" is set to "Device only" (i.e., GPS only), although I've tried turning "High accuracy" on to test, and it doesn't fix the problem.
I have Privacy Guard enabled on Citymapper, but access to location is allowed, and as before, disabling Privacy Guard for Citymapper doesn't fix the problem.

Citymapper "thinks" it's accessing location, but it's not: I say this because when I disable the location marker for the device (screenshot below), Citymapper complains that "Your location is disabled".

When location is on, Citymapper doesn't complain (so, it thinks it's working), but I know it's not accessing the location for three reasons:

the location Citymapper shows is incorrect (it shows the last "known" location -- see below for details)
the location marker doesn't appear at the top of the screen as it would when an app is using geolocation
in the system settings > Location, "Recent location requests" are shown, but Citymapper is not on that list.

Further to this, Privacy Guard reports that "Fine location" is being accessed by Citymapper every time I use the app, but it says that GPS was last accessed on 26 December 2017 (Privacy Guard controls separately access to "GPS", "Coarse location" and "Fine location").
Indirect access:
The weirdest part is that when I open a different application that uses geolocation (in this case, MapFactor Navigator) and the location marker does show up at the top of the screen, the correct location does show up in Citymapper as well (this is my current workaround, and this is how Citymapper gets the last known location I mentioned above).
What could be causing this, and how could I go about fixing it? As I've mentioned, it used to work but started having this problem a while back (perhaps around the 26th of December, since that was the last GPS access). I haven't seen this with other apps, but then again, I don't have a lot of apps with location access.
System details:

Device: Samsung Galaxy S5 Duos (SM-G900FD)
OS: LineageOS 14.1
Android version: 7.1.2
The phone is rooted with SuperSU.

Note: There's no "Citymapper" tag (and I'm a newbie), so I used the generic "applications" tag. Maybe a senior user can fix this.

Android Engineer at Citymapper here!
The issue you're describing sounds quite similar to one we fixed recently.
So I would recommend updating to the latest version of the app.
The current version in the Play Store as of writing is 7.1.

Thanks, @ted-eriksson! Works now. I was assuming that Play Store was letting me know when updates were available, so I didn't even think to do this (most basic) check. I guess you know what they say about "assume"...

How do I make an Android phone play sounds remotely?
I'm doing a Lego EV3 robot for a project. It needs to play sounds (like a soundboard app on a phone, but triggered remotely). Sadly, the speaker on the EV3 brick is too quiet for this.
I got the idea to use my old phone connected to a Bluetooth speaker. I want to hold my phone in my hand and with that phone, I want to make my other phone play short MP3 files. Without any wired connection. Sadly, I can't find any apps that already do this and I have no programming experience.
Is there another way to remotely trigger playback of a sound file stored on the phone? I'm okay with rooting the phone.

Have you tried AirDroid? It's very easy to use!
Or you can try something like LogMeIn. It's a cloud-based remote connectivity service a bit more complicated to set up.

You can install TeamViewer Host on your remote phone and TeamViewer on your regular phone. Setup is straightforward.
I use this for a similar purpose. I have a cheap Chinese surveillance cam which sends me an alert to my phone when an intrusion is detected. I want to play a loud sound when an intruder is detected, but unfortunately the camera built-in speaker power is too low. I had the idea of connecting an old phone to a set of speakers, then remotely controlling it to open the audio player and play a sound. I can easily accomplish this "manually" with this setup while I try to figure out how to accomplish this in a more automated way.

How can I check the commit message of AOSP
There is a bug in Android 4.3 and it is said to have been fixed in Android 4.4.
How can I know how it is fixed?
https://issuetracker.google.com/u/1/issues/36985755
Update 2018/03/01:
I searched with the keyword "mCurMethod" in gerrit and seems to find the related changes to fix it.
It is the commit. https://android-review.googlesource.com/c/platform/frameworks/base/+/68103
But IMHO, it is not merged into master because of merge conflicts.
How do we know how AOSP fixes it?
Git log in framework/base seems a lot of commit and is hard to locate the specific commit.

The Google Issuetracker offers an easy way to know the status of an issue: the sidebar.
Like any other issue tracking software, there are many different statuses an issue can be in.
To help clarify the status even more, there is a switch that tells whether or not an issue has been resolved and the changes are in "production" (ie. the current codebase of the project)
For your specific issue, the status is as follows:
Status
Won't Fix (Obsolete)
...
In Prod
(off)

This means that the issue hasn't been solved and will never be solved. It's probably not an issue anymore.

I think the issue once exists cause I met it before. And I found a possible commit for it (plz see my update) but it seems to be rejected because of merge conflicts. So how can I know how AOSP solves the issue.

How long does it take for a new version of an app to reach users?
I know that when a new version of an app is published to the Play Store, users do not all see it immediately. This is understandable; even Google probably doesn't want its servers being hammered when a popular app is updated.
I thought the delay was on the order of days, but now I suspect it's much longer than that. I turned off automatic updates because I like to be aware of when apps are updated in case a new bug is introduced. I check for updates every couple of days. It's not uncommon to see that an app was updated two or three weeks ago, when no such update was visible to me two days ago.
Can it really take three weeks for users to see updated versions of apps?

As far as my experience goes, as the release-manager for a popular app, once I roll out an update to 100%, I see the maximum adoption to the new version within 3-4 days.
Given we publish updates weekly and the app has a respectable penetration, YMMV.

I guess it depends on how the developer targets the audience .  If the developer chooses to do a staged rollout

You can release an app update to production using a staged rollout. With a staged rollout, your update reaches only a percentage of your users, which you can increase over time.

(Emphasis Supplied)
For more details see the link
It's best to contact the developer and check

Interesting. Actually, what prompted me to finally ask this question was that I was contacted by a developer to inform me that a new version of an app was out with a critical bug fix. It's only been days, not weeks, but I'm getting annoyed at Google.

Then you should check with him if this is the case

Dot a video file but still shows up in video gallery
I used to be able to hide video files in video gallery on my Samsung by adding a door in front of the filename.  After I change to Huawei phone, these files with dot in front just shows up like it is is not hidden anymore. Is there a change in hidden hide usage in android?

do you want to hide individual files or the entire folder contents?

Dot before a folder hides the folder. .nomedia within a folder hides the files contained in it from media scanner

Unlock android pattern after changing Gmail Password
My little brother had put a pattern lock on my old phone. I can't lose any data from that phone as It has many important contacts in it. so I'm not going for a factory reset. I had recently changed my password of my gmail account. Now I cannot access my phone through that gmail account. What can I do? The phone is Samsung Galaxy y with android 2.3.5.

On older Android devices, if you lock your phone using Google's find my device you'll be able to choose a new password, and you'll then be able to access your phone.
Go to android.com/devicemanager enter your email address and password. Now, press on lock. You will now see an option to put in a password to lock your phone with. After filling it out and pressing lock, You should be able to unlock your device with the password you chose.

Delete all files from an Artist/Album with VLC
VLC has the ability both to remove items from a playlist, but also to delete the filesystem data for a particular item or selection of items. To delete in VLC 3.0.1, open list of items, (e.g. by Artist, then Album) and then long press to select items. After selection, long press again to interact with a context menu which includes the Delete option.
However, I can't seem to find an option to delete all items in a particular set (e.g. Artist, Album) in one swoop. Do I have a way to delete these items other than by selecting them individually?

No, VLC does not offer the ability to delete an album or an artist in one swoop.
The issue was discussed in this thread Ability to delete an album/artists etc...
As stated in the thread:

That's because we don't support deletion on ext storage.
  This option would appear only for some album/artists with no clue for the user why.
That would be an inconsistent behaviour.

How do I root Redmi Note 5 Pro
I want to know how can I root my Xiaomi Redmi Note 5 pro running on Nougat based MIUI 9.2.4
I have tried searching for it but it seems that the phone is released recently so there isn't any information available

Not the time for that yet - wait for a initial TWRP port.

there is a way of rooting the Redmi Note 5 Pro. TWRP recovery is also available now. In the mean time custom ROMs may too be available. You just need to follow some steps which will get you easier to get root access. Then you can try audio MODs or uninstalling bloatware etc.

How do I delete an old device from my Google Acct?
so I have given my old phone to my mom and have forgotten to remove the my gmail account. I want to delete the phone from the "approved" list but I cannot find a way to delete it.
I've looked at various guides and the options/settings they are talking about are not available anymore.
I am looking at this page: https://myaccount.google.com/device-activity
Any ideas?
I'm trying to avoid changing my password since that means I need to change that on all my devices.
Thanks

If you are unable to remove the device from the Device activity section of your Google account because the red button doesn't show up, go instead to Google Security Checkup and expand Your devices, then tap on the 3 dots on the side of the device you want to remove to select the option.

It's quite easy. Click on the device you wish to remove and confirm as shown in screenshot below from my list of devices

Edit Try signing out of that account and signing in from that old phone and check if it shows up. Interestingly, for some users the remove button is not visible and there is an ongoing bug report for more than a year. You may like to add your complaint the and follow for updates

I don't see that option.

Can you add a screenshot of what you see and is the device you wish to remove listed or not?

Please see edit...

Afaik the remove button only comes for devices that haven't been logged into the account for long enough.

@xdevs23: That's not the case. Lollipop onwards if you want to factory reset you need to remove device from account to avoid factory reset protection lock. But showing devices used to be restricted to ascribe within last one month but that also changed - as you can see in the snapshot you see devices not active for more than a month

Alright then, didn't know that

1.) When I tried it via google.com/device-activity, the unknown device is listed, last used 4 days ago. The option to remove the unknown device is not available (i.e. no option to remove it, no 'red button'). However it does state that any unused devices after 28 days will be removed from the list. I changed my password 3 days ago.
2.) Going thru the "google security checkup" route, it only shows me a list of actively used devices, which does not include the foreign device.
So, I assume Google is the one who will "remove" the unknown device off my "device activity" list in 24 days. As long as I've changed my password I should be OK.

@reddy-lutonadio and to anyone else that seems to have the same problem I did just now, I had an unrecognized device on my account, a phone I have never owned, and the remove button did not exist, nor did the suggested fix you presented here work either, however, per the suggestion you gave, I discovered that a work-around did exist per your guided tip, however the remove option is not what was shown, sign out was the option needed that did the same job per your recommended link.  thank you, and if anyone else sees that same issue, you can follow that link, but click sign out of device instead.

Android data recovery
Hi I really need help on this one, my Samsung j1 has a broken screen, it's just blank and gives no visual. When I connect it via USB my laptop recognizes it, but I can't access the data because I have a pattern lock on the screen (which is needed to unlock the phone before the computer allows access), and the screen is non-responsive to touch. Can anyone suggest any software or anything that'll help me recover my previous data? Please help. USB debugging isn't activated.

Welcome to Android Enthusiasts! Looks like you've found the perfect tags for your question -- but might have missed the fact that our tags often also have wikis attached to them. Have you already checked with the "Data Recovery" section of our broken-screen tag-wiki? Or with our data-recovery tag-wiki? I bet you'll find your answer in the former.

Thank you for the help. Unfortunately it didn't help me but I understand more now, I'll try the otg cable but here's to hoping I can get the unlock pattern somehow

My huawei phone is not receiving text messages?
My huawei Y3II was working fine and receiving messages without any problem. But, one day I realized that one or two weeks have been passed and I did not got any text message. Then I checked by sending message from another phone but, I did not received. I have not done anything with my phone then, what could be the problem.

Don't know why but this may help 1. Restart the device 2 Clear  cache and data of the Messaging app. If this doesn't help try a different messaging app

How can I clear cache of my messaging app. With what name would I find my messaging app in all apps.

Huawei options are different but from Settings > Apps> Manage or show system apps > messaging> storage you should find clear cache and clear data .  clear cache and if it doesn't help clear data (you would lose existing SMS so back them up by using any app from Play store that does this) If you can't locate try an app like this but you should be able to find it with some search

Factory Reset has solved my problem. This also solved my second problem which was automatically turning off sometimes and then showing 'Starting apps' and taking too much time on it.
->  First of all I saved all my data to sd card and then switched off the phone and took out my sd card.
-> Then I reached to options by pressing power button and volume up button and releasing power button when logo is shown while continuing pressing volume up button.
-> Then I selected wipe data/factory reset option. It took just a few seconds to complete factory reset and then I rebooted the phone.

How can I reinstall basically everything on an LG G2
I don't know what happened, to be honest, it was a couple of years ago.
I rooted my LG D802 with TWRP. Because I was young and dumb and had no idea what I was doing, I decided to wipe the whole storage. Literally nothing is left except TWRP 2.7.0
My questions might sound dumb, maybe, i dont know, but here goes:
First off: Where do i get the files? Literally anything that is remotely related to an operating system is entirely gone. So i would literally have to install everything down to the metal. I remember trying to just flash a ROM back then, but that hasnt helped. Recently, i came to the conclusion, that it might be the missing kernel? Maybe im talking absolute nonsense, but i still havent really looked into that matter and im just trying to get my old phone back as a backup phone.
What would I need to get this working again? Is it possible at all? I have the Drivers and ADB Tools installed, but none of that has had an effect, flashing anything just fails miserably.

How to Check if Script is run once device is booted?
I have a script I need to run once, and only once the phone is booted.
I have attempted init.qcom.post_boot.sh, init.sec.boot.sh, debuggerd, and finally mkshrc
While my script ran with debuggerd, I found that it ran every time debuggerd ran, which is not something I need to happen...  thus when I stumbled upon /system/etc/mkshrc   (the other 2 simply did not work)
What I found was, the script runs that one time, on boot... however, it also seems to run every time adb shell runs, along with (I assume) everytime shell is fired up... which is also undersireable.
So, what can I do in /system/etc/mkshrc to ensure my call to my script runs only the one time... at boot?
I thought about running a while loop to check for the getprop sys.boot_completed if it == 1 then dump a file somewhere, and through an if statement inside the looop to check for that file, if exists then exit, if not then run the next command...   however, everywhere I am allowed to dump that file, it persists between boots, so that next command never runs again.
NOTE
Does not need root to do this, nor does my script need root to run (yes, I have confirmed)
CODE
BB=/system/xbin/busybox
MYPID=/mnt/sdcard/.kev-run

while [ `getprop init.svc.bootanim` == "stopped" ] ; do
    # if the run file does not exist, and we are stopped
    if [ ! -e $MYPID ]; then
        # run the scripts, then create the run file
        LOG=/mnt/sdcard/Download/kevs-scripts.log
        $BB rm -f $LOG;
        $BB echo "Launching Kevs Scripts" >> $LOG;
        MY_SCRIPT
        # write the run file so we aren't running this everytime this file runs
        touch $MYPID;
        sleep 1;
    fi
done

# if we are still booting, delete the run file
while [ `getprop init.svc.bootanim` != "stopped" ] ; do
    # we're not done booting, remove our makeshift pid file and sleep a second
    $BB rm -f $MYPID;
    sleep 1;
done

Seems to be off to me

mkshrc is by definition run every time an interactive shell is started, so it’s the wrong place.
You really should hook up your script with Android’s init system instead. (Sorry, I can’t give details on how to do that; I don’t know the Android ecosystem well, I’m just mksh’s developer.)
Writing to a file in tmpfs (so it’s auto-removed on poweroff) is usually a good approach for a script to run only once. However, I’d be surprised if Android’s init system wouldn’t provide such a facility; it’s the ideal tool for your job.

yeah, noticed that.  I'm hooking into debuggerd again, and utilizing setprop to set a non-persistent "flag" now

i wish I could hook into init.   or even compile a kernel for it (which would be much much better), but alas... it's a Verizon, with a locked down bootloader so I'm limited LOL

Well, there’s this but the accepted answer does not work on all phones as /system/etc/init.d/ support is a CM(IIRC?) addition. Patching init.rc seems to be the generally correct solution. In general, service …\n\tdisabled\n\toneshot seems to work; don’t forget to chmod +x it and copy to the correct partition beforehand.

I wish I could.  on a G935V, and it's bootloader locked, so root is the only thing we really have.  I ended up utilizing debuggerd as my "firing" mechanism, setting a "flag" via setprop   but what I'm finding now, is once root is removed, setprop no longer works.
My goal is to get some tweaks to work without having to root.   I have confirmed that some do indeed work, while some dont (which is expected), but the trick is getting them to fire off on boot... once :)

I forgot to mention, I can root/unroot my device at will.   Rooted, everything works just fine.  Unrooted, debuggerd throws a permission denied, so I think what I need to do is figure out the proper ownership, sepolicy, and context for it in order to get the permissions right... almost there LOL

Android phone animations have stop working
As title suggests it is a very strange problem I am facing. My phone has stopped showing usual animations instead it just gives jerk effects, or freezes,
1) for example the traditional google play store animations when you click on any apps,
2) another example is of loading bars, which just freezes and doesn't perform its regular animation.
I have attached small video files to make this more clear with both aforementioned examples.
Another examples to support this are in my android applications which I develop, none of the progress bars or animations work. All loaders just freezes like mentioned in the videos, I use some reveal animation libraries and fancy loaders libraries as well and their animations also don't work.
I checked to see the settings whether I messed up any settings or not but could not find it. Can anyone help me make solution out of this.
My model is samsung S5 neo running Android 7.0.
Thank you in advance.

In developer options does changing values of Windows / Transition animation or Animator duration make a difference? Wild guess

Excellent... That was the issue.. I missed it somehow.. but I have never accessed that options so I am not sure how it turned off. But Thank you tons..

Glad it helped :)

The animation scale options are turned off in developer options and by turning it on it works as expected..

There are many options to activate animation. Don't be afraid to select all of them.
In my Case I select 'Animation Scale 1x' from the list after clicked.
Also, switched off  'Remove/Delete Animations'  from accessibility configuration menu

Multi-window: prevent the out-of-focus app from pausing?
Android 7.0 introduced the native multi-window API which allows apps to be viewed in split-screen mode globally.
However, in actual usage, one downside prevents it from being as useful as some users would imagine. Many apps, when in the multi-window view but not in focus (i.e. user is interacting with another app in the multi-window view), pauses its activities: IM apps would no longer update incoming messages; music/video apps would pause playback; games would not proceed with their actions.
The official developer guideline briefly mentions the pausing behavior, and from what I understand, apps need to be programmed with this in mind so as to not exhibit it. But is there a way I can force the way around the limitation as a user? From what I've heard from fellow users, certain manufacturers' Android forks such as MIUI do not show such pausing whatsoever.
TL;DR: Can I prevent the out-of-focus app from pausing in multi-window?

@beeshyams YouTube is one known example of respecting multi-window (well-written), not sure about MX Player. I only asked this because some of my friends asked me about it when they're playing games (popular in China), and I did some tests and noticed some of my IM apps pausing as well. It probably is just Chinese developers not abiding by the guidelines, but the question stays the same.

Early this November, Google has confirmed that multi-resume - running two apps simultaneously without pausing - will be part of the next major Android release (Q), thus indirectly confirming that this functionality is currently not a part of AOSP Android.
However, Google also stated that...

To help developers provide the best user experience on multi-window
  with minimal effort, we're allowing device manufacturers to keep all
  apps resumed when in multi-windows in P.
To opt-in to this behavior in Android P, add the following meta-data
  in your app manifest:
<meta-data android:name="android.allow_multiple_resumed_activities" android:value="true" />
How to test: There are no device at the moment with this behavior but
  device manufacturers are working to update existing devices to allow
  developers to test. Stay tuned for more details from device
  manufacturers.

This implies that such functionality will be available in Android P at a later time. As of now (December 2018) though, there is zero reference to allow_multiple_resumed_activities in AOSP Android code, meaning that the time has yet to come.
Sources: Google Blog, XDA-Developers

Android Q beta was released on March 13, 2019, marking the first public debut of the multi-resume feature on non-OEM Android. Unfortunately, there's still no reference to allow_multiple_resumed_activities in AOSP Android P code (Q not open-source yet, obviously), and the "There are no device at the moment with this behavior" statement didn't change in the aforementioned blog either - the situation remains unchanged for the majority of users and the custom ROM community.

As of the formal release of Android 10, multi-resume has been made the default behaviour, as indicated in the multi-resume design page.

No that's not something you can effect as a user, or a developer. The multi-window behavior is defined by Android and any device that calls itself "Android" has implement the rules for multi-window life cycle.
The bottom line is the app needs to be coded to respect the resume/pause vs. start/stop differentiation. Prior to the invention of multi window the distinction between the two was tenuous at best. Now it actually matters.
In my experience, Google apps do a great job of working with multi window and it's hit or miss with everything else. YMMV.

I would actually live with the explanation, if it weren't for some users reporting that some Android forks have worked around it...

@AndyYan is right, some forks seens to "ignore" this life cycle.

I'd be really surprised. To be called "Android" you have to test a comprehensive test suite and I'm sure a little something like violating the Activity lifecycle would fail it. The start / stop / pause / resume semantics for multi window / display are well documented. https://developer.android.com/guide/topics/ui/multi-window#lifecycle

Why am I getting a red tint in the lock screen in Oreo 8.1/Nexus 5X?
I just updated to Oreo 8.1 from 8.0 and I notice that the lock screen has the same image as before, but with a red tint over it, like a layer of pure red with opacity 20% had been overlaid on top of it.
I never got that in 8.0 or earlier.
I thought it was due to a certificate from AdGuard and the resulting "Your network may be monitored", so I uninstalled the certificate, but the warning disappeared while the tint stayed (I have to say I haven't rebooted the phone without certificate).
I didn't change any setting about system colours, and in fact the rest of the apps and system show the usual colours, only the lock screen changed.
What are the possible causes of the red tint in the lockscreen in Oreo 8.1?

By any chance is night light activated . Check in your quick settings

@beeshyams it's not available on stock Nexus 5X/6P, only from Pixels and up.

Google support says that the tint is based on the colour of wall paper and there is no way turn it off. That's for Pixel phones and perhaps same applies for yours

Like you said the color tints are based on your wallpaper. I've found it typically does a nice job with this sorry you don't like it. There is not a way to turn this off.

Edit The colour tint applies to lockscreen too going by Android Police blog

Lock screen
It looks like the lock screen does this as well. However, the effect is even more subtle there.

That was not about lock screen, but I guess it's the same issue. After all, I have persistent notifications in the lock screen.

Added source for lock screen in answer

In the Google support OP mentions dislike for the effect on lockscreen

When I uninstall WhatsApp from Android device, would my chats'/msgs' data stay on device?
so i made this stupid mistake of uninstalling whatsapp then giving away my phone without resting it to factory settings, so the other person now have my device, could he by a way or another retrieve my uninstalled whatsapp data? In other words, when we uninstall whatsapp, does all the data related to our whatsapp msgs and chats get deleted or do they stay in some form that could be retrieved? I don't know the guy very well so i don't trust him and i'd really appreciate to know what's what so maybe i could make a plan. Thank you.

If you have just uninstalled whatsapp and given phone to other person, then otherperson can have all data(whatsapp, google, gmail etc). Its recommended to reset before any sale options.

All your pictures and videos will still be on the phone

If your Google account is still active on that phone, then just go to 'lost phone' option online and format from there.

There are two separate issues

Factory reset was not done , so it's technically possible to retrieve data but this would involve sophisticated methods not in the reach of an average person
As far as WhatsApp is concerned , when you uninstall , the data is  not accessible even on installing again since you need to authenticate the telephone number , which I presume it
s with you. WhatsApp database is encrypted making it more difficult to retrieve messages but your WhatsApp pictures, videos and audio can be accessed

IMO, unless the other person is very savvy technically, it's not a cause for concern but then in future do remember to encrypt your device and factory reset to ensure that others cannot access your private data

His gonna dowload his own WhatsApp then put in his own number,the back up of his WhatsApp will appear not yours,remember before going into WhatsApp after downloading it requires you to confirm your number,he cannot do that with someone else's number only his,so do not worry your WhatsApp info is safe and sound,they backed up on cloud somewhere,waiting for the rightful owner and his unique number.

How can I set an alarm for the first Monday of each month?
I can set an alarm for every Monday, but how can I set one for only the 1st Monday each month?
I can have calendar events set in Google that are for first Monday, is there a way for an alarm to be set on a calendar event?

You didn't mention whether you are willing to buy an app to do this. I recently got an app called Alarm Plus Millenium that I see can do this (and lots more).  I mainly got it for its task manager abilities, but I also needed a newer alarm clock app to replace my old unsupported Gentle Alarm, and this app was the best I could find for what I wanted.
Also, FWIW, I've had some email exchanges with the developer, and he was very responsive, quick to reply, and although in Paris, was very proficient in English (my only language).
Just saw your question about setting an alarm for Calendar events.  Yes, Google Calendar allows you to set all sorts of alarms for the events.  You can set more than one if you want.

Is there a way to prevent specific apps from using geo-location functionality/permissions when not running in the foreground?
Is there a way to restrict an android app from using permissions when running in the background?
For example, news broke recently that MoviePass is tracking location before and after movies (source)
I'm OK with using geolocation when the app is in the foreground... but not when I otherwise think it's off/closed.  Is there a way for permissions to be more granular?  I've heard that Apple devices can/do limit location services to apps running in the foreground.

AppOps provides more granular control for some permissions.

Yes and no.
Some versions of Android allow control of a background activity manager.  In Android 9, the Adaptive Battery function can be used to force certain apps not to run in the background.  There are also 3rd party alternate apps which can provide the same functionality.  This means that there is a way to prevent geolocation whenever the app is not in foreground.
However, if you need to keep the app running while in the background, or if you are specifically interested only in a permissions based solution, the answer is no - not without root.
With root an app such as Tasker could be set up to run a task that modifies another app's permissions every time it is triggered.  See for example this Reddit post: https://www.reddit.com/r/tasker/comments/79yjrl/change_other_app_permissions/

Window animation scale of 0.25 on OxygenOS 5.0.4?
Is it possible to set the window animation scale to 0.25 on OxygenOS 5.0.4? The closest options I see are 0.0 and 0.5, but I'm hoping there would be a way to do this with root access.

If there isn't option in developer settings for that value of animation scale then there is this app. App doesn't require root but you'll have to grant some permissions via ADB, you have guide how to do that when you launch app.
Now when you do that under miscellaneous section there are animation speeds where you can set it to any value you want. Keep in mind that when you restart the device in most cases all modifications you made with app and permissions you granted are gone so you'll need to do it again. I say in most cases because to me sometimes happened that everything is fine and sometimes I needed to do it again.

+1 thanks! I actually just found another one but this looks great too.

It seems jOnePlus Tools can do this.

Downloading certain apps on CM 12.1/13 causes it to bootloop
I flashed Cyanogenmod 12.1 on my 1st Gen Motorola Moto G (aka. Falcon) successfully through TWRP. Afterwards, I flashed gapps on my device (from OpenGApps.org) successfully. I set up my google account on it and everything with no problems.
However, after I had started downloading WhatsApp on my device, it crashed and restarted. Instead of giving the the "Warning: Bootloader Unlocked" message, it cut straight to the Cyanogenmod logo and started bootlooping. This would stop if I went into TWRP's File Manager, and deleted the files for the app in /data (or if I did a factory reset, which would also delete those files).
This had happened to me multiple times with multiple apps with both versions 12.1 and 13 of Cyanogenmod. Is there a way for me to have these apps on my device without it bootlooping?

Last friday WhatsApp updated on my Redmi Note 4 running LineageOS 13 and it crashed everything I had running in the background and then it just bootlooped... Something is wrong with WhatsApp. :s

In my case (Nexus 4 (Mako)), I have it running only on CM 10. WhatsApp then started to cause the boot loop on CM >= 11. Since I need a custom ROM for 4.4+/KitKat or up, I ended up in flashing LineageOS 14.1 (Nougat) and so far it's been working fine for me. (ツ)

Almost anything Google related keeps stopping
My wife's Pixel just started behaving oddly this evening.  Virtually all Google related services keep force closing with the error message "_____ has stopped" or "_____ keeps stopping".  There are various different apps and services that fill in the "blank".

Google
Settings
Google Play Services
Device Health Check
Google Keyboard

Additionally other Google apps, such as Google Maps, do not launch when started.  It just returns to the home screen without an error message. And when she tries to open Google Play, all she gets is a white screen.
A common suggestion I've seen both here and other sites is to clear the system cache, unfortunately she is running Android 8.1 so that setting doesn't exist.  Additionally because Settings force closes upon launching, I am unable to do it for the individual apps (besides, which app do I clear).  Another is to reinstall the Google Play services, but I'm unable to do so because Google Play closes when I open it as well as does settings so I can't roll it back there.
Since this started all of a sudden as soon as she returned home today, I'm assuming there is a bad update somewhere, but since I can't get into Google Play or the Setting to see the app details, I can't uninstall or reinstall.
I've tried booting into Safe Mode and I get the same error messages, so that won't be a help.
There were no apps installed recently, and if it helps, many 3rd party apps and games appear to work fine.
As pointed out in the comments, a factory reset would seem to be an option, but I consider that the "nuclear option" that I'm trying to avoid since it involves a lot of backing up and restoring that I don't want to go through.

Factory reset? Backup data before.

How to quickly switch between two apps on one half of the split-screen view?
I'm in this scenario a lot:
I'm using split screen opened to App1 taking the first half of the screen and App2 taking the second half of the screen. I frequently need to switch between App2 and App3 on the second half of the screen while keeping App1 on the first half. One way to switch between them is to tab the recent apps button then drag the app window to the second half of the screen. Unfortunately this process takes from 5 to 15 seconds each time I want to switch between App2 and App3, which is very exhaustive as I need to switch between them in a very frequent manner (About 3 to 10 times within 5 minutes).
How could I switch between App2 and App3 on the second half of the screen quickly just by some gesture and the apps get instantly switched without the need to drag or re-position the apps windows in order to re-fit the split screen each time?
A gesture example could be: swiping from the buttom edge of the screen to upwards on the second half of the screen (if screen is in horizontal mode).
Important clarification:
I'm asking about switching apps while being in multi-app split screen view. I'm not asking about single app view.
One example of apps which works very well for the single app view is EAS App Switcher. What I need is that when I switch to another app it's opened in the second half of the splitted screen (not the full screen which destroys the split screen view).
Let me clarify more. I have App1 and App2 active (in split screen mode). EAS will do the job if it replaces App2's window with App3's while keeping App1's as is. What it does is that it opens App3 on full screen (single app view) destroying the split-screen view and App1 becomes in the background instead of keeping App1 active and next to it is App3 on the other screen half.
It would be very helpful if exist some app or launcher that achieves this.
I'm on Android 6.0.1 on Samsung Note 4 with root access.

I have tested on Android Marshmallow, but it activates app in single app mode every time. I have also checked the setting and it seems there's nothing related to split-screen. It would be termendously great if it really supports split-screen on Marshmallow.

Here's a suggestion that works perfectly on a galaxy s5, and I'd assume that it's the same on a note 4.
While in split screen, long press on the back button. You'll now see all available apps on the left side of the screen. Drag the wanted app to the bottom part of the screen.
It's not as fast as you wanted, but it's two steps which would take less than 1.5 sec. when you're used to it.
Edit:
Found even a better way. Open app 1 and 2, now long press on the back button, and scroll to the bottom, you'll see an option called "create" press on that, and it will save the two apps as your preference. Now do the same while having app 1 and 3 open. Now to switch between the two, long press on back button, and you'll see the preset opting on the top left of the screen.

Wow. It's amazing. The only remaining struggle is holding the back button delay time. If there exist a way to a have a floating side movable button like in EAS app switcher to instantly switch between apps by tabbing, that will be the exact thing I'm looking for.

I'm unaware of a better way, but I'm sure this makes it MUCH faster then the way you had before...  I'll definitely be in the lookout for a better one.

note 3 and note 8
Are you aware of any issues with the Note 8 phones giving hot-spot access to the devices nearby if the note version you got is from another country or region? Does Samsung have restrictions still?
You may ask why I am asking such a question, and what the rationale is.
What prompts me to this question is the following experience I got.
I used note-3 (for years while I lived in in the US. ). No issues. But, when I brought it to Turkey, and put in a TURKCELL LTE simcard, I learned that it cannot give hotspot to my devices. (Whereas the iPhone 6plus which I also used and brought from the US ) does not have this issue with the Turkish Carriers.
Now I'm about to purchase a note 8 from Dubai (to use it in Turkey with TURKCELL ).  I'd like to make sure that if I put the Turkish sim card in it, I will be able to create a hot spot and my laptop will be available get its internet thru the note.
Do you have any information about any issues with hot-spot with note phones? Or is this an issue of the past?
Also, what could be the cause of not-giving-hot-spot access. As far as I remember, I believe USB & Bluetooth options did not work either.

AFAIK, certain carriers (especially US, and especially Verizon) would make changes to the device software so it prevents hotspot usage when a SIM of different carrier is inserted. I'm thinking you might have fallen victim to this on the Note3. Just buy an unlocked (not locked to carrier) device and you should be fine.

I think this is a pretty reasonable explanation to this problem. Thank you very much for clarification.

If you can make clear of the model number of your Note 3, I can judge whether it's a Verizon variant and if I should move the comment to a more concrete answer. Thank you.

It was an At&T phone. Do you still need the modal number?

Ah, yes, AT&T also does that provisioning quite often.

Can you install an app in a secure silo?
So I am learning Chinese and - because Google is not available in China - Chinese apps tend to be downloaded outside of the play store. To that end, a lot of news apps (especially the good ones which are offered by the state news organisations, e.g. CCTV) have ridiculously wide-ranging security-access levels (i.e. you have to agree that they can read your contacts, your accounts, camera access, the works - even though it has no logical need for such access).
Obviously, not too keen on giving the Chinese government full access to spy on me for the benefit of a news app, but is there a way of setting up a secure silo within Android, in which you can then install apps and dictate what access they can have?
In some respects, I would like to set up a Great Firewall of Europe on my phone and put the Chinese apps (or at least the ones which seem to come with added surveillance functionality) in there to stop them unnecessarily getting at my contacts etc.
Your help would be greatly appreciated!

Reroute requests for rear camera to front camera
My rear camera doesn't work (very well) and so I can't scan the QR Code which is needed to access WhatsApp web.

Is that possible?

How to enable usb debugging and install an apk to an android device with non-functioning display?
The display of my Xperia z3 is non-functioning(i.e. all I can see is a black screen) after an accidental damage due to water-insertion. But all other parts are working fine. The screen responses to touch, I can hear the touch sounds and I can click photographs as well with the camera key.
After connecting the phone with USB cable to my ubuntu laptop, I can browse through the internal storage files on the phone and locate the newly created image files as I click new photographs and take screen-shots. But I can't open any files(images/audio/videos) with errors like "couldn't load image" and "couldn't determine type of stream". However, I'm able to copy new files to the internal storage.
I want to install some screencasting application like vysor on my phone so that I can access it using my laptop. I know this can be done using adb commands but the problem here is that USB debugging is not enabled on my phone and hence I can't find it on the list of adb devices.
Is there any workaround for such situation?

see the broken screen tag wiki and other questions therein

So I guess the question here is how to enable USB debugging without a functional screen. Because from then on by using Vysor you can do the rest.

If the device is online and Playstore activated, you can trigger an app installation via https://play.google.com

yeah, primarily that's what I'm trying to do. @papakias

Unfortunately, the device is not online :( @Robert

I've heard that for some devices, if you put them in recovery mode, they can be seen by pc's without usb debugging turned on. I don't know though if you can install apk's or see the screen somehow :( It's just something that I remember I read somewhere.

How can I see which websites use up most of my foreground data?
Every month I use up most of my mobile data in Chrome. This is the foreground data, not background data, so the data saver settings don't do much.
My plan is to avoid those websites that use up most of my data. But to do so I need to find out which websites do so.
My mobile data usage only charts per app, and while I know it's chrome, I have no indication which website is most to blame.
Is there a way of recording this, either in the browser via flags/policy/settings or on a system level (system settings or another application)? I've used VPN apps as a  firewall previously but they ended up using a lot of battery.
How can I track website data usage on chrome?

I don't think there is a way to get a granular record (I may be wrong) but you can try the app mentioned here and to see the network usage opening a single chrome site at a time. That could possibly help you in identifying data hogging sites

As I discussed a similar issue here: Android app to show what apps/processes are currently using data. The same workaround is applicable in this case too.
I will focus on this specific part however:

How can I track website data usage on chrome?

It is still possible using the mentioned tool: Network Connections

To get website specific usage just open the app and navigate to Current Connections Tab.
The log is given in two formats i.e IP address or hostaname. If you want the Ip address resolved to hostname simply tap, Resolve IPs to Hostname option.
It should appear like this:

I produced this log, when I was browsing StackExchange website, and from the screenshot you can see it gives the data usage associated with the website an if you open another website it also shows data usage specific to that hostname and sub-hostname associated to that particular website.
Only part that I am not sure is giving a very finer log on per website basis that can be stored as a seperate log, AFAICT you could periodically start live capture of traffic and see the sites which generate a lot of data usage.

Do your know why it wouldn't show the amount of data sent and received? All I see is the connection status (TCP established etc.)

You mean on yourdevice, can start a live traffic capture?

Yes, I can follow the steps in your post but I don't get the same result.

Samsung Galaxy tab E new SD card shows no free space
Good day,
Trying to save some films onto a brand new SD card on my wifes Samsung Galaxy tab E. She has downloaded Showbox and when we hit the download button the screen shows 'no available space on SD'. It's a 32GB Sandisk by the way. The system recognises it, and I have moved a couple of apps over to test it and they transfer ok. I formatted the card before I started and it is getting a bit frustrating now. Anything I am not doing ?
Bill

Sd card could many times mean the local storage. Make sure to select in the app that you want it to go to extremal memory.

There is an 8GB memory on the device of which 4.3 is taken with mostly Google stuff we don't need that can't be moved to the external disk. I have just been through all the programmes cleared all the data, and moved what I could to the external SD so we are left with things we don't need and unable to move them taking up an awful amount of space. I was wondering whether a reset to as new might do the trick. The Showbox app is one that cannot be moved either.

Factory reset will not clear up too much space, as the phone takes up allot of memory on it's own

A bit stuck then. It is a micro disk. If I put that in my pc, downloaded whatever films required and then moved that back to the tablet, would that work?

If you're able to download it as a video file on your computer, you should then be able to move it to your sd card and play it in the regular video player, but probably not the showbox app

I don't have show box, but are you able to download videos from a browser? Or does it have to be the app?

Answer to both, we are using the Showbox app only because it has the latest films. I might try and install that on my PC which is where I am writing from. I don't watch them myself but the wife is away on holiday shortly and wanted to take some films with her and I thought downloading them would be easy. Thanks for the replies.

What Android version is running on the device? It might simply be that the app doesn't get permission to write to "external storage". Go to Settings and check whether r/w access to storage has been granted.

It's an Android 4.4.4 and I don't know how to do the last.

Lost Phone, I want to locate my phone
Can I get the location of my phone it does have WhatsApp on it,
I lost it about 20 hours ago and it was online(life) on WhatsApp 11 hours ago
I tried google-locator but it is out of reach because I switched off background data.

Welcome to Android Enthusiasts! Have you already checked with our lost-phone tag-wiki? You're not the first asking this question ;)

You can try locating your phone using Google's find my device option. Just go to Android.com/devicemanager log in, and it will show you the location of the device. If it doesn't show your location, in that case your location option is probably off, or your phone is off, or it was factory reset.
WhatsApp doesn't have a function to find your phone. So unless you had a different app that does that, you might be out of luck.

You could try reflashing it maybe. Try LineageOS.  I'm not sure why but no standard OSs seems to work differently sometimes.

I really dont want to reinstall the os. It was working at one point, but now its not working.

Cheating KNOX by cracking stock ROM certificate
I had some thoughts about KNOX and the fact that flashing stock ROM doesn't trip my KNOX flag. I did some research about the topic and I learned that KNOX checks ROM file's certificate or something like that. The files within a zip archive have .md5 file extension. Knowing a fact that MD5 is flawed hashing function which is considered broken so I can theoretically crack the password which it used to create md5 file checksum. Having this password I can sign a custom ROM with it and KNOX should be bypassed successfully. Are my thoughts correct and it's feasible or I misunderstanded something?

If it was that simple it would have been broken long back. Knox is almost fool proof and prevents any such attempts

Samsung KNOX addresses security using a comprehensive, hardware-rooted trusted
  environment:
• Hardware Root of Trust
• Secure Boot and Trusted Boot
• Security Enhancements for Android (SE for Android)
• TrustZone-based Integrity Measurement Architecture (TIMA)
• TrustZone-based Security Services

Source: White paper on Knox by Samsung
You can see the technical details but to summarise any changes made trigger a fuse that would flag tampering

(Fuse is)...one-time
  programmable memory area (colloquially called a fuse) is written to indicate suspected
  tampering.

Next, hardware root of trust is specific to each device and that  verification would fail
Even flashing an older version of  stock ROM would trigger the fuse

Rollback prevention fuses are hardware fuses that encode the minimum acceptable version of Samsung-approved executables. These fuses are set at manufacture time in the Samsung factory. Because old images may contain known vulnerabilities that can be exploited, this feature prevents approved-but-old versions of boot executables, from being loaded.

To summarise, you would see that it won't work

So there's no way to cheat KNOX? Any exploits, vulnerabilities?

Not that I am aware of.

Bluetooth with Moto G4
I recently purchased a Motorola Moto G4. My husband has the LG wireless headphones. I tried to pair but every time I would get a phone call the voices would come over garbled like they were under water. I thought it was the headsets due to I also fought this with my last phone LG Phenix 2, so i went and bought another pair. These are called Warrior BT2. When I finished charging them up i paired them and made a phone call, same problem. i was ok as long as i held the phone but if i even went 1 ft from the phone it would cause issues. Where i live I don't have great service so when i find service i have to leave my phone in that spot. What can I do to fix this or do I need to go purchase the higher end ear phones? my husband's was 70 dollars and i still fight this. Please help

As a quick Google search will confirm, the Moto G4 series was notorious for the Bluetooth quality being poor, especially with BLE capable device, and also interference from WiFi... Does the problem get better if you disable WiFi on the device?

Hi thanks for commenting. I didn't know about the Wifi. I will try that and let you know

Yeah, on the 2nd gen Moto G you couldn't use BLE at all while Wi-Fi was working. Getting all these radios to work at once without interfering is a tricky engineering problem, and it looks like Motorola just doesn't have those skills.

How to make a restore image / export ISO to restore later?
My Samsung galaxy S6 edge+ from Verizon came along with a lot of bloatware I really do not need.

First of all it has many pre-installed apps from google which is sadly the case for every android phone I bought till date. These apps can only be disabled under normal circumstances and cannot be uninstalled.
Secondly there are apps from Samsung as Galaxy add-ons which I know I will never use.
And lastly there are apps from Verizon like Verizon tones etc.

Saddest part is that most of them are redundant like I have two browsers (Chrome and Samsung Internet), two galleries (Google Photos and Samsung Gallery) and the list goes on. They eats up a lot of storage even when I have cleared all their data and disabled them. I decided to root my phone and uninstalled all unnecessary apps. Now everything is good.
But now I want to reset my phone and I know it will wipe out the whole content thing but will restore my phone to its initial state. Initial state means return of all those useless apps too. All settings, launcher preferences, gestures and automation things gone. Do I need to repeat the whole thing from  very beginning to regain current state? So My question is:
Is'nt there a way that I simply make a restore image or back up my current OS state to somewhere or export an ISO or whatever which I can restore later on to surpass all those steps?

Answering the last paragraph of your question first
Since you have rooted the device, flash a custom recovery meant for your device  (Google on XDA for your specific make and model) and take a nandroid backup (click on that tag and read the wiki) and restore /system to restore the way it is
Next, factory-reset will not undo the changes you made to the /system, it only affects /data. Which means apps you uninstalled will not be installed but yes your launcher settings will not survive. That's why it's better to go for Nandroid backup to restore with minimum effort

HTC One M9 factory reset problem
I need to do a factory reset on my HTC One M9. Just for clarification, I have not rooted the phone ever. I'm trying to do a factory reset through the phone setting and once I do the reset, it brings me to the bootloader. I'm not sure what to do from there. I try to boot it into recovery mode, but it says "this build is only for development purposes only"
Any help?

You can try this-- (for Hard Factory Reset)

Remove SD card and SIM card. Switch of your phone.
Press and hold volume down key along with power button, release the power button when vibrates.
Navigate to reboot to bootloader with volume keys and select with the power button.
Then select BOOT TO RECOVERY MODE.
Then select wipe data/factory reset.
Then Yes – delete all user data.

But as you mentioned that it says "this build is only for development purposes only". Then you can try resetting from the setting menu.
The detailed process to reset M9 by setting menu and Hard Reset is given here.
If none of the methods works, then you may need to visit the service center.

How does Firefox Mobile decide which text to scale up?
Consider this screenshot of regular desktop version of the site Stackoverflow on Firefox Mobile:

As can be seen, some text is larger than other. This odd text scaling only seem to appear in Firefox Mobile. On desktop, or in other Mobile browsers (that I've checked) the site appears normal.
I tried to inspect various CSS and tagnames but couldn't arrive at a conclusion myself. <p> and <span> tags seem to be larger than others. I also don't think it could be any other CSS property as it would work on other browsers as well.
It seems to be Firefox Mobile that's doing all this, but how does it decide which text to scale up?

Possibility text-size-adjust which is non standard and that's why not detected using other browsers
Extracts from MDN document

Because many web pages have not been developed with mobile in mind, smartphone browsers differ from desktop browsers in the way they display web pages.....

Because text that has been scaled down to fit a small screen is very small, many mobile browsers apply a text inflation algorithm to make the text larger and more readable. When an element containing text uses 100% of the screen's width, its text size is increased until it reached a readable size, but without modifying the layout.

This property only works on smartphones and some tablets

All files of the internal memory are duplicated on an LG G6
I have an LG G6 (has Android 7.1. An update with Android 8.0 is announced but not avaliable yet) with an SD card. The SD card went corrupt for some reason and after a phone restart, all files in the internal memory are listed twice. Somehow, a virtual folder named /sdcard/ (locaded at /storage/emulated/) is created and just mirrors the internal memory. I did a factory reset and the problem was fixed, but the SD card went corrupt again and the issue re-emerged. Is there a way to fix it without having to do a factory reset again? I'm not sure if it is completely related to the existence of the actual SD card either.

Android 7.1.1 showing insuficient space even with plenty of space in SD card formatted as internal
I have a ZTE Maven 3, it comes with 8GB of internal memory so i bought a 16GB microSD and formatted it as internal storage with the built-in android option to do so.
Problem is, when i try to install new apps the PlayStore refuses because i dont have enough space, but even if the internal storage is at full capacity, the SD card is 90% empty !
What is wrong with this?

You have to keep your internal storage empty because all the apps which you download from play store gets into your internal storage not in your external storage, even if you buy a sd card of 128GB or 256 GB you will not be able to install apps if you have full internal storage
Suggestion: Move all your photos ,videos, downloads to your SD Card
manually and  especially delete that .Thumbnails folder(Hidden Folder)
in DCIM in internal storage.

Once I've done that, my apps are still taking up too much space. I'ved tried moving all the apps I can. Is there anyway to view/debug what's hogging the space?

My phone display turns off automatically even though the feature is set to never
I own a Asus ZenFone 3 Max running a Nougat. From the past few days, my phone screen turns off automatically if left unattended for at least 10 seconds approximately. I have my "sleep" feature under "display" in settings set to never. But this still happens. What may be the problem?
*I did get my screen broke like from a month ago. But I hadn't faced such an issue from last few days. So maybe I don't think if I could actually relate that to this.

Edit:
My phone got an app called Mobile manager which have something called the power master.

Again the power master opens as:

I then tried checking out the option called Battery mode:

and customized goes as:

Does setting it to 30, help?

@ABochur No. I just tried it yesterday. There weren't any positive results actually.

Is there any battery saver or something?

@ABochur No power saver actually. There is an app called the mobile manager which have an option called power master. I have add screenshots of the these and some other ones in the edit ( of the question. )

Feel that it is due to the power master app.If that is a pre-installed app, disable it from settings and see if it helps. If you installed it yourself , uninstall that. Since that app is not available (for me) on Play Store, it may be pre installed and some setting in it over rides the choice you made

@beeshyams I tried it now as you said. Still no use. The screen turns off after 10 secs.

Probably related to hardware changes you made since your question implies that this problem is a recent one

Where is Samsung's SIM manager in '/system/app'?
My custom ROM's SIM manager is broken, so I have to replace it with the official one but when I install it, it says the package exists by the same name. I need to replace it manually in '/system/app' yet I failed to locate the folder.

Check here: /system/priv-app/SimSettingMgr/SimSettingMgr.apk  its name is com.sec.android.app.simsettingmgr

It is very likely that this individual app doesn't exist, instead it is embedded within the setting app. However you can still create a SimSettingMgr folder and put your apk in there and push the folder to system/app or system/priv-app and reboot.

How to restore deleted pictures from LG K8?
I accidentally deleted some pics of my daughters that was sent in a txt. I found some recovery apps to get them back but my phone has to be rooted.
How do I root my phone and what does it mean?

Welcome to Android Enthusiasts. Kindly look into this for basics of rooting.

You will not need root access if the device runs android 5.0 or above, A photo recovery software is able to recover photos easily without root due to the new changes in Android 5.0 and above, It's still not clear why Android has left this out of the root only features but it's still handy.
The first thing to remember with data recovery is that deleted files are not actually deleted but rather marked as replaceable files ready for new data to replace it, this means you should not to add any new data to the device or it will overwrite the deleted files, so if you fill up the device with more photos, all the old ones will be non repairable ( unless you have software that is powerful enough ) .. Some people say it's possible to repair a file that has been overwritten 7 to 36 times but i don't believe that..
Anyway, the first thing you should try is DiskDigger
This link is to their no root version Photo Recovery
A tip for using disk digger :   Sometimes changing the default storage path in settings > storage will allow DiskDigger to scan the SD Card as the internal storage. It's sometimes helpful to reverse the default storage device between scans if you couldn't find the files you're looking for

What are RAM , ROM and their types used in Motorola smartphone?
Well I know some basic information about RAM and ROM.
RAM is Random Access Memory with two main types i.e. SRAM and DRAM.
Whereas ROM is Read only memory. There are five basic ROM types:
1.ROM
2.PROM.
3.EPROM.
4.EEPROM.
5.Flash memory.
Below is the screenshot taken of Motorola G5S which says smartphone have 4GB RAM and 32GB ROM.
I want to know little bit more about particular types of ROM /RAM (from the types given above) used in the smartphone and reason behind using them. Can anybody tell me?

RAM is volatile, so the premise of your question appears flawed.

Moto G5S uses LPDDR3 DRAM, which is volatile (cleared on power cycle) Random Access Memory which can be confirmed with an app like DevCheck, and a 32GB flash storage chip which is non-volatile high-speed electrically programmable memory that is common to most modern cell phones although sizes can vary widely.
Modern cell phones do not have a "ROM" or Read-Only Memory so to speak, although the term ROM is often used as a misnomer for the operating system... such as "My phone is running the custom ROM called LineageOS." which in this case is referring to a custom operating system residing in the /system partition.
That said, many OEM's use the term "ROM" for the embedded storage in the device. Technically, this is not the correct the term for it at all. The storage, or ROM as the OEM is referring to it here, is the embedded storage flash chip which is usually partitioned with some parts accessible to the user and others protected from normal user access for use exclusively by the system.

Scan and recreate QR code
Does anyone know of a way (preferably a single app) that could scan and recreate a QR code?
Eg. I point my phone at the code, and then I could display that code on the screen, so it can be scanned again by some other device. This is different from simply taking a picture of the QR code since it takes me longer to get a nice photo of the code and even if I do, the quality is still quite bad and it takes too long to scan the code with the other device.

Most likely the ROM you've flashed is not for the same model of phone that you have. Check again the model number written on the phone and the model number the ROM is for. Note that Samsung often releases different models of phone under the same marketing name.

About apk installation
I have doubt on installation of apk file. Where does the apk file store RAM or ROM ?
As we know that RAM is  volatile memory and ROM is secondary storage and also  when is system shutdown, is the data  erased from RAM?

apk files you install are usually stored in /data/app which is typically part of the /data partition on your internal storage. What is the problem you are having, are all settings/applications/data erased when you reboot? Sounds like a hardware or ROM problem. Please update your question with your specific device, Android version, and clarify the issue. Thanks.

There is no accessible ROM in Smartphones, only FLASH. Apps are installed to FLASH memory and loaded from there to RAM.

Welcome to Android Enthusiasts! I have modified the content of your question, if wish it to edit it further please do, but make sure the question is clear enough to attract a good answer.

Just to be clear, where I used the term "ROM" in my previous comment I was referring to the operating system and it possibly being corrupt, not "Read Only Memory".

Method to block calls on dual SIM and block notifications from some apps (scheduled)
I recently got a Motorola G5S Smartphone with Android 7.1.1 with Dual SIM. One SIM is work-related, the other private. Also, every App on my phone is either work-related or private.
I'm searching for an app (or integrated function) which can do the following:

block all calls & messages coming into the work-SIM at night & on weekends
block notifications of the work-related apps at night & on weekends

The tricky thing here is that I do want to use the mobile data from the work-SIM, so disabling it completely is not an option.
I checked out Tasker but the description doesn't say anything about blocking calls coming in to one of the numbers/SIMs. On the other hand, the "Do not disturb"-option also cannot to block only calls to one SIM (at least on my phone).
Is there any other app or even built-in feature that I'm missing? Rooting the device would not be a problem, I guess.

@beeshyams That might be OK for an "internal" work number, but if the number of the work SIM is published, it might be getting called by people not in the contacts list at all.

Right, but the point is that an unknown contact might be a work or a personal call. Maybe the questioner is happy to treat unknown contacts as always one or the other; it would be helpful if they could come back and clarify.

An ideal solution would be to block or allow calls depending on the number/SIM. But I think, a block depending on the group (I have a private and a work address book) plus blocking unknown contacts would also be fine.

Caveats

OP is willing to reject unknown numbers in weekends
They have their office contacts and private labeled in their address book
Only office people call on office SIM , they are not aware of private SIM number and vice versa for private contacts
They can continue to use data from Office SIM
Not tested on dual SIM but should work

I don't think it is possible using SIM based approach, alternative non root automation approach using macrodroid which is simple and easy free up to five macros ( App link )
Blocking calls in off times
Create a macro and name, save it  (Add Triggers,  actions and constraints by pressing +)
Triggers

Call Incoming → Select Groups →  Office (office numbers stored in contacts and grouped by this name)
Call Incoming → Select Contacts → Non Contact (additionally select Unknown caller if required)

Actions
Call Reject
Constraints
Day of the week → Saturday & Sunday
add constraint of  AND /OR /XOR/ NOT → OR (ensure the little inverted triangle shows OR)
add constraint Time of day → set start and end time for example 2000 to 0800
what it does is that on weekends OR during specified times calls made by non contacts  / unknown numbers and office folks are rejected
Test it by changing triggers and constraints . Use the 3 buttons menu → Test Macro

Blocking Office app notifications
Trigger
Notification → Notification Received → select apps → choose office apps from drop down → Text content → Any
Actions

Volume change → Notification → Set slider to zero
Clear Notifications → select apps → choose office apps from drop down → Text content → Any
Volume change → Notification → Set slider to the level desired

Constraints As in above macro ( Hint: from 3 dot menu use clone macro to get a copy of macro to save repetitive selection)
What it does

Action 1 mutes the notification volume to zero ( you don't need to hear the ding when you don't want to be notified)
Clear notifications during the time / day chosen in constraints
Action 3 restores desired volume level so that you can hear other other notifications that you  want to

For testing: Long press on triggers for instance and disable it . add a trigger that is convenient like a friends phone . Once the testing is done long press to enable.

Haven't tested fully ,so let me know if there any issues

Reading your comment under question again, this macro can be modified to choose numbers instead of groups. Selecting numbers from a large list of contacts in the drop down is painful. I know how bad it was to select a dozen contacts, and created a group to facilitate this for myself. If that works better for you, you can go do that

What is qualcomm.qti.autoregistration process for?
I was using 'netstat' for Android and I discovered many processes called 'com.qualcomm.qti.autoregistration' LISTENING on several UDP ports (IPv4 and IPv6)
I have a OnePlus 3t running Android 8.0 and OxygenOS 5.0.2.
Any ideas?

These are processes related to the functionality of your device hardware.  com.qualcomm.qti.autoregistration is the full package name of the process, where "qti" stands for "Qualcomm Technologies, Inc.  The "*.34xxx" numbers are probably ports.  I'm unsure what the  "autoregistration" process actually does, however.  My hunch is that it has to do with WiFi calling.

Thanks for your help. I already knew about the qti and ports part. But I couldn't find info about the autoregistration process.

Move apps to the SD card and keep them there
I have a phone with a very small internal memory (LG K7, just 4GB storage, running Android 5.1.1) but a nice roomy (64 GB) external SD card, so naturally I use an application manager (specifically, AppManager III) to move as many apps as possible to my external storage.  For the most part, it works fine.
But every time one of these apps updates the new version is (by default) installed in my internal storage, and I have to move it again.  This happens at least 2-3 times per week, especially for apps like Facebook, Twitter and Messenger, which update very, very frequently.
It's very frustrating to have to manually instruct my phone over and over again that, yes, I want to move the app to external storage again.  Is there a way to just set this once and forget about it?  One option, I guess, would be to turn off auto-updates.  But what I really want is a way to configure things so that the auto-updates are auto-moved to the external storage each time they are re-installed.  Particularly looking for methods that don't require rooting my phone.

There are many similar questions to read here and this really should be labelled a duplicate. This issue is unresolved over many years. Some background can be found through reading results of this query

How to rid Contacts app of phone numbers showing as duplicate entries
Problem description:
This is the typical duplicate contacts scenario where a contact name does not show up when being called by that number. The problem is, named contacts have been duplicated into their phone number formatted counterparts. This has seemingly been caused by WhatsApp as only contacts with WhatsApp have been duplicated.
I.E., at the time the duplication occurred, Contacts app had 600 named contacts which "automatically" duplicated into 470 numbered contacts. Therefore, 1070 contacts exist, with no way to merge.
Research and solution attempts:

Contacts > Settings > Merge duplicate contacts, produces no result
Contacts > Settings > Contacts to Display > Custom List > Deselect WhatsApp contacts, shows only the named contacts but still doesn't show the named contact when being called.
Syncing the contacts to Google, only syncs the named contacts, so merging cannot happen there
Refreshing contacts in WhatsApp produces no result

Other information:

CLI (Caller Line Identity) is turned on and had always worked prior to the issue arising - most notably if a named contact does not have WhatsApp, the contact name shows when being called currently.
Samsung Galaxy S6 Edge with Android version 7.0

Partial Working Solution:

Deleting numbered contacts 1 by 1, produces "You cannot delete contacts from read-only accounts, but you can hide them in contacts." [Cancel] [Delete]

Clicking [Delete] does produce the desired result but I'm looking for a more elegant fix. For lack of better words, to merge all named contacts and numbered contacts, without deleting them 1 by 1.

Try this app. I bought after testing it. YMMMV

Disable "com.package.name has stopped" pop-up notification
I am typing, and then, a pop-up flies into the screen, telling me that a random application in the background has halted.
Starting with Android Lollipop, the "OK" button of the pop-up is terribly small, and is greyed out for one second. Tapping on the background behind the pop-up does not work.
Apparently, Android is unable to send a notification instead of pop-up on app crashes, so it decides to block the screen like the infamous iOS volume indicator.
How do I disable the app crash pop-up?
I am tired of waiting one second and pressing "OK" each time.

Try using Macrodroid. Create a macro Trigger: Notification Received> select app > any> contains text > add the text you see in notification ; Action: Clear notification> containing text (repeat text)

Revert navbar back to the right side of the screen under 270° rotation
Since Android 8.0 (Oreo), when the device is rotated to 270° rotation, the navbar will go to the left side of the screen instead of staying to the right (as in 90° rotation):

As humanized as this sounds, it conflicts with some of my launcher/wallpaper mods, and also forces me to use the left hand under 270° rotation, so I don't see the change as beneficial and would like it reverted.
The answer could be decompiling and modifying SystemUI, or even modifying the Android source code and building (I have the know-how for that) - one just have to tell me where and how.
Any ideas?

(I hate Google enforcing more and more UI changes I dislike with every Android release...)

@beeshyams Not sure if it's a 8.0 or 8.1 trait - LOS is now 8.1. I'll go check some vids to make sure and update the tag accordingly.

Looked it up a bit and it seems to be a thing in Nexus/Pixel devices starting as early as 7.1. Manufacturers might've merged the change according to their preferences. For LineageOS, best I could find is this commit which probably is responsible. I'll see if reverting it does the trick, but I bet there will be a lot of conflicts that make it hard if possible at all...

This seems to be what's calculating and determinating the navbar layout. Will try hands at it when I have time.

As my investigation shows, Google calls it "Seascape Navigation Bar View" and deems it as a feature. This part of the code inside the Android framework determines whether the new left navbar layout should be used if 270° rotation happens. Making it still return NAV_BAR_RIGHT in the case effectively reverts the change. Tested side-by-side on a LineageOS compilation done personally.
Unfortunately for end users without access to source code, I don't know of a way to alter the behaviour yet: on older Android versions this change is supposed to be reflected in /system/framework/services.jar, but since Oreo it has both been split into a new /system/framework/services.jar.prof file and odexed, so currently available tools can't touch it as far as I know.

For the above reason, I'll leave the question open for now, so anyone with the know-how of altering the new file format can chime in anytime.

Data Warning Slider Missing
I used to have 2 sliders, a warning slider & a limit slider, now just a limit slider is present.

Is data usage warning toggled on? Or did they remove that option too?

There never was a toggle for warning bar. I was sliding warning bar up to be as close as possible to limit bar when it disappeared.

So you were dragging it up and it disappeared? What happens if you drag the limit bar till you catch up with the other one?

It would only come within 5, 10, or 15 MB's of limit bar, depending on if usage was low or higher, and it would stop sliding. However, the last time I slid it up as close as it would go next to the limit bar it disappeared.

You can try clearing the data for the settings app. Settings > apps > settings > storage > clear data. Although that might not be worth it for what you're trying to do, as that will revert your settings to the original ones.

Bought a phone on eBay, want to reinstall Android, but not sure which one to use
I bought a phone on eBay named XGODY 5.5" 3G 5MP 8GB, and I want it to go back to the stock version, but how do I know what is the correct ROM to install on this phone?
Here is what the "About phone" says:

Is there any OEM related information in Device Bootloader?

Not sure, how would i check that?

There is no such thing as a "generic" phone. ROMs need drivers that are specific for the specific processor, specific memory chip, specific camera module, specific cellular radio, specific Wi-Fi radio, specific Bluetooth radio, specific GPS chip, specific LCD screen, specific digitizer, etc.
From the eBay ad you linked to, the manufacturer of your phone is XGODY and the model is X15S. Here is a link to the manufacturer's website.
Now, you need to find a ROM that was specifically made for the XGODY X15S. You can use your favorite search engines with such keywords as xgody x15s stock rom.

Is it possible to stop play-store from updating all the apps automatically? (some automated way, not via settings)
I know there is a setting in Play-store, 'do not auto-update apps'. I am not looking for that one.
I am looking for an automated way, like using ADB or some other code by which I can stop apps from auto-updating.
EDIT:
I have root access, though it is better if it can be done without root.

There is separate flag for each app too. Auto update is a flag in Play Store and not particular app, so you can't use adb to toogle  that.

@global_warming I changed that flag in database to 0 (don't auto update) but still when I logged in from my google account, they got updated, while 'auto_update' column for each app remained at 0.

Can I install an APK on a new Android device before the setup wizard runs?
We got a bunch of Google Pixel 2 (Android 8.1) devices for our employees. We want to install the Microsoft Intune Company Portal for Android app and a LOB application.
To save time, we don't want to go through the setup wizard on every device. But the main requirement is that device should look and feel like new. When the employee turns the device on, he should still be presented the the setup wizard.
The device must not be rooted.
Is this possible?

Sorry, Android 8.1

Not 100% sure, but afraid not. To get the APK unto the device, you'll have to turn it on. And to install it e.g. via ADB you'll have to turn on [tag:usb-debugging]. So the next time you turn on the device, it's no longer the first boot and thus the setup wizard won't be started. Only possible way around I can see would be via a custom recovery – which requires to remove the [tag:bootloader-lock].

Why do refurbished android phones have 3 months warranty or, no warranty?
I am planning to buy an Android smartphone, but I don't know whether I should buy a refurbished phone or not. I checked many websites and most of them say that their refurbished phones function like "NEW", but they give only "3 month" warranty. If refurbished phone's performance is SAME as the Brand new phones, then why they do Not give 1 year warranty? I am confused !

Refurbished phones are those that have been returned by customer due to hardware or software issues under replacement warranty.
These are then repaired, issues fixed and sold as refurbished phones by EBay etc and they carry less warranty because they are not covered by OEM or carrier warranty but warranty provided by these third parties which are lesser in duration -after all the cost is also significantly lower !
Nobody can guarantee it will or won't be as good as OEM direct sale phone performance - caveat emptor

as they are NOT giving 1 year warranty, does it mean that the refurbished phone will NOT last long as a Brand-New one?

Nobody can guarantee it will or won't. It's caveat emptor

but, if everything is working "perfectly" in a refurbished phone, then why can't it have a one-year warranty?

Like I said it's not the OEM selling it, it's EBay etc doing it and warranty costs money. Why should the company support you with complete one year warranty when you are paying less ? You get what you pay for

Flash the stock ROM on your device

how can I do this?

Search in XDA or your device forums

can I do this without pc?

If you just want to access the Playstore, use the Yalp Store app. However, if you need to buy an app, or use one that needs to check its license with Google, that won't help.

You need a computer in order to flash your device. It is probably a mediatek Powered phone.

You can try mounting /system and copy Play Store apk to /system/apk the restart device.

The password to my google account is stored on my Mac via KeyChain (it is a long and random character password). Is there any way for me to send this password to the tablet over bluetooth/usb? I tried creating a txt file and putting it in the downloads folder on the tablet but it does not see the file.
I am not able to download any apps to this tablet without this password, so I can only use the apps that are loaded with android.

Do you have a file manager on the tablet?

Or an app called "files"

@ABochur I don't see any app called files. This N7 is running Lolipop btw (the latest official OS it supports)

"I tried creating a txt file and putting it in the downloads folder on the tablet but it does not see the file." Can u explain that part? What method did you use, and where is this Download folder?

@ABochur I used the file transfer program, it showed one of the folders on the tablet was called Downloads - there's a Downloads app on the tablet

so you tried using using Bluetooth to transfer the file, or did you use something else?

@ABochur usb. I'm not sure how I'd do it via bluetooth. Is there some magical built in facility for sending and receiving things from a Mac via bluetooth similar to AirDrop?

not sure about Mac, but allot of Microsoft computers, have Bluetooth capability.

It seems like without Bluetooth or a file manager, or wifi, your best option might be to simply read of the code, and enter it into the tablet. I mean, how long can it be?
