Long wait after flashing
I have a stock image for my tablet, and I am using DragonFace to edit it and PhoenixSuite to flash it.
The stock image flashes fine, and after the flash it immediately reboots (I don't have to do anything).
I can make changes to it via DragonFace and save it as a new img file.  After flashing the new file, sometimes it won't boot at all, sometimes it takes 5 min before it will boot.  I try many button combinations to trigger a boot.
Obviously, it could be a bad img (if I changed something critical) some of the time, but that isn't the case most of the time.  I know this because after a bit of waiting, the device does boot.  If after a few minutes there is no activity, I sometimes reflash the exact same image, and it boots (eventually).
My main question is how to shorten the long delay between flashing and booting.  It is making diagnosing my new image difficult.
Note, I disabled device encryption, and I know that works because the image flashes just fine with that modification (again, after a short wait).

In general, after flashing any Android OS, the first boot takes too long because how Android works. I think it takes too long because is "optimizing" all the apps (compiling to be run on ART) or something like this, and configuring stuffs. And it depends also on your hardware. AllWinner/RockChip CPUs are not powerful though.

I would think that, but there is no screen activity and adb can't find the device.  Also, when I flash the stock image, it boots immediately.  After flashing a new image, it is for all appearances dead.  Buttons do nothing.  Then magically after a few minutes (sometimes) it boots up.

So this depends on how you modifying your image

Agreed, I am using DragonFace.  If I open the stock image, make no changes, and then just save it as a new name and flash it, it does this.

I was about to point Dragon Face. I think the way the stock image is packed is different than the one Dragon Face does

That does appear to be the case.  If you are aware of any other such utility, please let me know!

Unfortunately I don't know any other ROM tools/utility or editor for AllWinner devices

Look into the simg2img tool.

Yeah, looks like my best bet is to switch to linux and use command line tools rather than windows tools.  Thank you for the help!

LG Stylo 3 on Cricket, Wi-Fi randomly disconnecting
I got an LG Stylo 3 on Cricket last month, and already I seem to have a problem. Randomly, it will disconnect from Wi-Fi. When I go into the settings, it'll say that the network is disabled.
Any idea what could cause this?

I had the same problems, did all advice given, but this one thing I did helped.

Go to Settings
Click on Wi-Fi
Click on Wi-Fi Manager
Click on box if checkmark on

Now it connects and stays connected, at home and everywhere else.

I followed your instructions and it still disconnects

From OP's (now deleted) comment,

The problem got solved. I turned off Cricket Wi-Fi Manager as Jess in the replies said, then in Advanced Wi-Fi, turned off "Switch to mobile data."

i cant enter recovery mode; how do i install my ADB driver?
Here is my issue. I have an LG g Stylo 3 Plus, (T-mobile). I can't get into recovery.
Here's the situation:

my screen is broken and I have a semi picture. However its unresponsive.
I had no need to root this phone before. So device is not rooted.
I enabled knock code. So I have important calls and texts that I am not receiving.

So I need to use ADB to unlock my phone and also side-load a mirror to pc apk.
I am familiar with ADB commands and have tried everything within my knowledge. I have also done extensive research and yes, I did also using the search bar.
Any ideas how to make this show up in adb without entering recovery mode?
so just to make this clear. I'm completely lost.

May I recommend you a look into our broken-screen tag-wiki? You're not the first in this situation, so some of our existing solutions might apply.

If you display is at least partially usable, you may use a USB/micro-USB adapter to simply plug a computer mouse to your smartphone. From there and depending on your screen damage, you may more easily interact with your device.
Also, remember the screen rotation settings : if your ROM allows 360° rotation (i.e. 90°, 180°, and 270°), you should be able to see any part of the screen by turning it on the sides, and/or upside-down.

how to stop motorola moto G5 from automatically rebooting?
I have a Motorola Moto G5S (it is displayed exactly like this in the about/status config) running android  7.1.1 (stock ROM from my telecom)
Sometimes it reboots out of the blue, even when I am using an app. The device is not having any storage shortage, or overheating.
Is there a way to stop it from doing so?

You need to determine, or bypass, the cause... This often required a factory reset and is often a good place to start. Factory reset and determine if the problem exists, if it does it's likely bad hardware and there is nothing you can do. If the problem is gone, add apps a few at a time to determine the culprit... It's a simple process of elimination. This isn't a simple tick box fix saying "don't reboot", it will get uncomfortable if your not easy with a factory reset.

Assuming you have keep a stock ROM on your phone (don't have root it), the cause can be both hardware and/or software.
I explain myself: either the cause is material, or a heat problem putting the temperature sensor(s) on alert or even the components themselves overheating thus obliging them at a given moment to stop. In this case, you would already feel a significant increase in warmth with your bare hand when picking up your phone.
The last possible cause of this scenario would be a design flaw, it seems to me that this phone is recent, perhaps reason why this kind of trouble starts to make edge effects and therefore untimely restarts.
The battery may also be involved, voltage variations that would no longer power the phone enough for a few seconds, forcing Android to turn off.
The second hypothesis, namely the software, therefore in this case Android, could be the cause, in this case, the diagnosis could become more complicated than for a material cause.
Indeed, it could be that a system or user application poses a problem. If the last words i quoted don't scare you, then you might find an anomaly in the system log files, namely in the logcat, an explanatory tutorial has been written very well on XDA, i let you read it:
https://forum.xda-developers.com/showthread.php?t=1726238
Always in a software case, the problem could simply come from an old application, not updated for a certain time that you would use to perform a very precise task in a very precise way.
I would suggest you to make a complete backup of your data on your phone before anything else, and this in a separate way (a backup of each type of data such as SMS MMS and call log on one side and photos, videos, music on the other side). Then a simple cleanup of the data partition, cache, as well as the dalvik cache through your reovery menu, followed by a reboot to test your phone.
By hoping you find this information useful.

"SIM Tool Kit: Error in application" pop-up always shows on Lenovo Vibe K5
I have a Lenovo Vibe K5. The phone screen always shows a pop-up message saying:

SIM Tool Kit
Error in application

How to fix this issue?

please try this, go to settings->apps and clear cache and data of sim toolkit app. OR check for any settings available to block notification(pop-up) of that app.

Check if both SIMs are activated or not. If not, kindly recharge and activate it. The pop up will not come.
Ex. I got this error due to Airtel SIM and my SIM's incoming outgoing was already stopped. I also got the same error, also tried all things posted on internet and YouTube. I recharged RC 35 and it automatically resolved.

MacroDroid asks for "Application Launched/Closed" accessibility permission constantly
I'm on non-rooted Android 8.1 Oreo with MacroDroid Pro v3.24.1. After I got a replacement phone and reinstalled MacroDroid, it constantly asks for accessibility permission: Application Launched/Closed.
There are three accessibility permissions available:

MacroDroid
MacroDroid Fingerprint Gesture Detector
MacroDroid Volume Button Monitor

I enabled the first and last and kept the fingerprint off as this disables drawer swiping. I don't get where to allow that accessibility permission it is asking for.
Any suggestions?

I am an avid user of MacroDroid and noticed this issue with two devices and raised this issue on app forums (accessible from within the device and my post dated 24 December 17- unable to link)
This is what the developer said

It's not a MacroDroid issue but a system issue that can happen with any app.
If you Google the issue you will find stuff like this:
Accessibility services gets disabled automatically

I find this to be true, since I had this problem on stock ROM but not on custom ROM
Quite possibly same case with you

So what is the full link ? (currently badly formatted and can't be followed ...)

Judging from the last word and the context, it might be Accessibility services gets disabled automatically or Accessibility services get disabled automatically

Thanks Andrew//@SRG..sorry for delayed response. Did not see your comment earlier. Fixed

How to remove apps which doesn't allow uninstall option without rooting smartphone?
I'm using Samsung J7Max recently I updated MY AIRTEL app and try to uninstall it app uninstalled but leaves an duplicate MY AIRTEL app which tell me download MY AIRTEL app from playstore. I can't remove it or disable it. Don't know what to do. Here is snapshot of duplicate Airtel app.

Is airtel app was there on first boot? Did you install airtel app from Playstore OR by downloaded apk? Please explain how you installed that app. It seems like airtel app is a system app.

I always install apps from Google playstore..

I want to get rid of it.. help me remove it.

do you remember that it was there on first boot? System apps are built-in apps like Google. You cannot uninstall them.

I think no. I have checked.

After purchase, you open the box and turn on. You can see apps like Google, gmail, Web browser, camera etc. Have you noticed airtel app along with this?

No it is not pre-installed app. I have uninstalled many time Airtel app but nothing leave app like this. I'm sure.

May be a factory reset solve this. Backup data before reset. Otherwise please wait for a good answer.

I think I should wait..

Even I scanned with  JIO security (norton antivirus) but nothing cames out.

If it is installed as system app (and not being able to uninstall suggests that), it cannot be removed without root powers (or flashing a clean ROM that comes without it).

@Ashish Try this: https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

From what I understand :

MY AIRTEL is a system application that's installed in the /system
partition
Updates to this app are stored in the /data partition

Without rooting your phone, you only have read access to /system, and read/write access to /data. That's why you can uninstall MY AIRTEL updates (which are in /data), but not the app itself (which is in /system). And since Google Play has a newer version, you'll be prompted to update it again, etc.
Rooting your phone will allow you to gain write access to /system and hence uninstall any system application.

Your question specifically asks for a no-root solution, which is difficult but not impossible if you are willing to use a temporary root through ADB.
Connect to your device via adb and enter adb root, mount the system partition, and delete the APK thats in your system partition.
This may not work for all devices, as it can be difficult to get true root in production build on many devices. good luck.

Screen black during phone call and it won't come back during call
I have an Xperia XZs with Android 8. Lately I'm having problems while calling. When I start a call, the screen goes black immediately, and won't come back anymore during the call. The result is that when I'm in a menu where I need to chose a number, I can't, because the screen is black. I can't even hang up. Well, I can pull out the sim card, and that will end the call, but that means a restart.
I've installed a new dialer, and that seems to help a little, but the problem is still there.
Is there any way I can get my dialer back to normal? Is this a new bug? I updated recently.

The screen protector has an opening for the proximity sensor. This opening collects dirt along the edges. After removing the dirt, the problem is gone.

The proximity sensor take charge of your screen when making a call
Factory reset your phone or change to custom ROM. If the problem still exists, you've to change the proximity sensor on your phone.

That's an explanation of the behavior, but not a fix of this problem.

How does one change the proximity sensor of a phone? And why is it always a factory reset you recommend? Wouldn't it be better to try calibrating the sensor instead? Such an app could also detect if the sensor is working properly. If it does not, it might be necessary to sent it to a service center. A factory reset hardly helps then.

Something is filtering blue light and I can't figure out how to stop it
I just got a Samsung Galaxy S9 last week and since day 1 it has been applying a blue light filter even though I turned blue light filter off in the settings (Blue Light Filter turned off and also schedule turned off under Settings/Display/Blue light filter).
The blue light filter's behavior is strange. The filter turns on around 6:56 every evening and turns off around 5:56 in the morning. Sometimes when I unlock my phone the filter isn't applied and a split second later I see it get applied. Even less often I see it applied in blocks quickly filling the screen. If I turn blue light filtering on in Display settings, the affect is additive.
When I got the phone all of the applications from my previous phone, a OnePlus 3, were installed, so I supposed it could have been one of those. I went into application permissions and turned off overlay permission (Settings/Apps/Special Access/Apps that can appear on top) to everything I thought might be affecting the screen color.
What else can I look into? Is there a way to check every process that's running to see what is changing the screen color?

Do you have Auto Brightness set ON? If you have recently turned it OFF, did you flush the usage data?

@wbogacz Auto Brightness is on. I've only briefly turned it off while trying to figure this out. Where do I flush usage data?

Tap the Auto Brightness LABEL to bring up the submenu where you can flush usage data (At least this is functionality on the Galaxy S8). If the option is disabled, temporarily turn Auto Brightness ON, flush, then OFF again.

Flushing usage data did not work.

Next, and my last, theory hinges on the times you have stated in the post, and the regularity. Do you have some sort of automation tool installed and active like Tasker or IFTTT? They have means of controlling environmental settings via time-based, or location-based, triggers.

Nope, sorry, nothing like Tasker or IFTTT

This is a wildcard - do you have Developer Options turned on, under the section "Simulate Color Space"? I think this is an option to test Accessibility for the color blind?

I don't see this option, but I did go through all Accessibility settings, paying close attention to Vision related, and they are all disabled.

Just making sure you saw this thread about using adb to disable a buggy night mode: https://forum.xda-developers.com/galaxy-s9-plus/help/weird-night-mode-type-issue-t3764161 or use Nova Launcher https://www.reddit.com/r/GalaxyS9/comments/85blz5/psa_night_light_and_blue_light_filter_overlap/

@morrison-chang The reddit post was it, nearly exactly. I did the transfer from my previous OnePlus 3 and the night light settings transferred over and were hidden by Samsung's software. I already use Nova launcher, but didn't know about the Activity widget. Please post your comment as an answer so I can reward you the bounty.

So I did a bit of digging and found two related threads describing your problem:
User Friendly Solution
As you've described you had transferred over your settings from a different device and the 'Night Light' settings were hidden by the Samsung software.
The most user friendly way is from Reddit:
PSA: Night Light and Blue Light Filter Overlap
where the solution is use Nova Launcher and to create a Night Light shortcut from Nova Launcher:

Easy fix is through Nova Launcher / Activities. Press somewhere on the home screen so you can select widgets. From there select Activities>Settings>Night Light. Open Night Light from your home screen and turn it off - and the scheduling, too, of course... Unless you'd rather use Night Light.

Reddit author made a video for visual aid: https://youtu.be/J9J1B2Q8Eu4
Alternate ADB solution
In my research I also found a different way, and while it didn't help you perhaps it may help someone else:
Weird Night Mode type issue
The XDA one lists adb commands to try:
Using adb to list out device settings
adb shell 'settings list secure

and then attempting to clear the appropriate ones:
adb shell 'settings put secure night_display_activated 0'

adb shell 'settings put secure night_display_auto_mode 0'

I landed on this question + answer for a similar problem on a Motorola Moto G6 instead of a Samsung: the screen takes a slightly red-ish tint in the evening until the morning.
For the Motorola phone, there is an independent set of screen settings which includes a night mode (it's a blue screen filter with a schedule, not a black and white mode).
To access it, open the "Moto" application, head to "Features" ("Fonctionnalités" en français), expand the "Moto Screen" settings ("Écran Moto" en français), then enable, disable or configure the "Night screen" (Écran nuit" en français).

Any way to make a device believe that an app was downloaded from play store?
Is there any way to make a device  believe that an app was downloaded from play store, not having to turn off Unknown sources?

Is there any way to make an believe it was installed from the Play Store, sure... Can this be done easily? Probably not. If you can figure out how it is verifying this information we might be able to formulate a solution. Also, knowing what app and it's source, the device, why you can't just install it from the Play Store, etc. would be very useful information. Also be aware, if this is an attempt to "pirate" an app, we will not assist you in any way.

@acejavelin ok,edited my question to make it more proper.

Turning on Unknown Sources does not stop an app from checking it's validity, it simply allows loading an application from a different source. And no, you cannot install an app from outside the play store on a device without enabling Unknown Sources.

Possible to use another application as default camera application?
Many apps let u use only the default built-in camera app. They not allow you to choose a third party app, such as the app "fake camera". Is there a way to remove/replace the default camera app? Any ideas?

Yes, it's possible. At least, on some devices. But without knowing anything about your device, it's hard to answer your question.
For example, on Android 8, you have a menu like this: If you have a search option in your settings, then you can easily search for "default", and you will find it easily.

Changing default camera is unfortunately disabled on Android 11 and newer, see this answer

Android auto - non stop notifications
I have been using android auto using car display for more than a year on nexus 5. No problems at all, well except from huge battery drain on Nexus.
Couple of weeks ago updated the phone to Samsung Galaxy s8. Android auto connects and works except for the one part. If I get any notification e.g. on WhatsApp, phone goes in non stop notifications tone. By that I mean, whatever sound phone plays for WhatsApp message notification keeps on playing. I have tried disconnecting phone from android auto, killing all applications. Nothing works. Only recourse is to reboot the phone.
This only happens when phone is connected to android auto display in the car. Otherwise notifications are normal.
On the lighter note, first time this happened, it was almost comic for me. By sheer coincidence I had low fuel signal and WhatsApp message within seconds of each other. Unfortunately, the tone setup for WhatsApp is very similar to car warning. I thought my car has developed some sort of issue and warning me about it and decided to pull over. Only after killing the engine, I discovered that noise was not stopping and found the phone was the actual culprit.

This seems to be more like related to Android Auto functionality in mentioned applications themselves. Do you have, by any chance, an ability to do some tests in some other Android Auto-enabled car, to see, if the problem persists there as well?

Between numerous updates of whatsapp and android auto and phone service packs, issue automatically resolved. Don't know who the culprit was - as it developed automatically after few days, it did resolve automatically after few days

Why cant i access my google account on a new phone when I have not factory reset my old phone
I recently bought a LG Stylo 3. It is the EXACT same brand and model of my old phone.
I bought a used phone from Offerup but I know it is not locked. The person who sold me the phone did a factory reset to it right before selling it to me. I called Metro PCS and activated the newly bought phone.
I tried to sign in to my google account and i entered all the information correctly. but it tells me i have to wait 24 hours before attempting to sign in again.
I waited 24 hours and the same message prompted. I waited 72 hours and the same thing.
How can  I prove I am the owner of the Google account and allowed to use my new (used) phone?! I am frustrated because Google does not have a service to call or even text.
The phone is not locked, I have all the informations and I can still access my information easily on my old phone. Can I add a new device to my google account before activating it?
Essentially this is not an issue of a used or new phone, it is an issue with my Google account and thus if my old phone (that I am forced to use) breaks then I am completely screwed.
How does Google have a multi billion dollar business if they dont have customer service help??

Did you try logging in to your account from a computer instead? May be you have some security mechanisms enabled such as 2-factors auth and such...

I'm confused... You have your Google account credentials and can log into it on any device except this "new" phone? You said you watched this person do a factory reset, but did they remove their Google account first? If not, then the phone maybe locked to the previous ownets account...

You mean that you had to wait 24, and 72 hours to be able to logon again to your google Account. So apparently Google have warn you several times before block your IP (i think).
Concretely, some information is missing in your tracking subject, namely the types of protections you have set up on your Google Account (confirmation email, confirmation SMS, secret key by Google Authentificator, etc).
It also lacks the essential information to know what the exact error message Google is displaying on the screen.
In your security center on your phone connected to your Google Account, do you have any alert related to your problem? This famous Google security center is generally accessible via the phone's settings menu.
In yet another solution, the user has the ability to create special accesses for third-party applications (allow Outlook to access your Gmail account, allow access to your Google account through a Windows Phone).
Maybe you could create a particular access for another type of device, Google will then provide you with an access code, it will want to write it down (without spaces), then enter it as a password to be able to access your Google Account without having you blocked again.
We hope this alternative will help you.

Completely disabling cellular data and limiting apps only to WiFi when available
I've recently (2 months ago) purchased my first smartphone. I'm on a sort of prepaid contract (I pay what I use in terms of calls and SMS and it's automatically withdrawn from my bank account).
For years I have been paying like 6-7 EUR per month (at the most!). I don't like using phones in general and smartphone is a new thing for me but I bought it just for the cheap GPS and camera (not the mobile surfing). After the first month I got a surprising 30 EUR bill. Every once in a while I was getting notifications about new mail, or Skype messages etc. and I was wondering why this was happening (I know, I sound like a member of the Flintstone family) because I never enabled mobile data transfer. As it seems it is turned by default.
I went to my service provider and the guy deactivated the data connection. To my question "Can I just block any Internet activity through cellular connection for my number?" he told me that it's not possible (why he did not explain). Just to make sure things were all set I even put a data cap on cellular data at 10KB. In addition I have also limited updates of apps only to WiFi that is if I'm connected to a WiFi network only then apps should check for updates and download those.
I've just received my bill for last month (the second month of me using the smartphone). And this time it was just painful - 81 EUR. I checked my bill's details and I saw the following strange reoccurring Internet traffic:

22.05.2018 10:05:11 Internet 39 Min 2,9410

All in all 68 EUR without VAT, 81 EUR with it.
Needless to say I am far from happy.
I started digging and checked the data use for every single app. Almost all apps had the background data use (cellular connection) enabled by default. I wan't sure what the background data is so I read a little bit.  The descriptions is also useful namely: Enable usage of cellular data in the background.
I checked some of the apps (like YouTube) and I saw that while 80% or so of the traffic was foreground many times there were couple of hundreds of megabytes background data.
I disabled all background data use now for all apps but I wonder if that is not the case why I got that fat bill. If that's the case there are multiple things that bother me namely

why did the cellular data limit not kick in? In the stats for cellular data I still get literally no data being used
why even with data connection disabled cellular is used at all?
why am I not getting Skype, Hangouts etc. messages, new email notifications, Chrome shows I'm offline etc. if cellular  is indeed enabled?

Especially with Google Photos (I have syncing between my phone and the online service enabled) the situation is horrible - 466MB foreground, 2.08GB background between 10th of May and 7th of June.
What else am I missing? Clearly the guy at the shop didn't help and I'm very new to this smartphone thing. I simply want to use Internet (any sort of Internet connectivity) ONLY when I'm connected to a WiFi network (home, work).

If mobile data is turned off, that shouldn't happen. While my answer should provide you with measures to drastically limit your bill: could you please [edit] your post and include a screenshot showing mobile data is turned off? Just to rule out it might be "the wrong switch". Also include a screenshot of that 10k data cap please, to remove similar doubts :)

I think your carrier should be able to block your data access, if you ask them for this. Maybe you should call them on phone. Didn't you think about switching bundle? If your currenr one is old, you might find a better one, with lower prices, and included data cap. For example, in Hungary, they either limit your speed or block your internet connection if you reach the included ammount of data.

Check out datally

First, "not possible" is a straight lie. The carrier is perfectly capable of turning that feature off and limit you to "calls and SMS only". They simply don't want to.
Second, you could try some Firewall app in whitelist mode (i.e. by default all apps are blacklisted). Take e.g. a look at NetGuard (I recommend taking it from F-Droid, though it's also available at Playstore). This firewall app doesn't require rooting your device, and you can set up mobile-data restrictions separate from WiFi:

NetGuard: List of apps, settings for a specific app, defaults (source: Google Play; click images for larger variants)
As the screenshots show, you can set the default to "block mobile by default", so you don't have to take care for new apps unless you want to allow them.
Third: I find it very strange that mobile data are summing up if you have disabled them, that shouldn't happen. But using a firewall app, you should at least be able to reduce that massively.

How can I take a screenshot of the notification bar dropdown?
Sometimes I get a notification in the notification bar, I pull it down, and then I want to take a screenshot. I press the power button to make the screenshot, a menu appears to either shutdown, restart or make a screenshot. When this popup menu appears, the pulldown menu disappears. I've tried another screenshot app, but that didn't work either.
How can I take a screenshot of the notification pulldown menu?

Isn't the normal way (volume down + power button) working?

I don't think you can, but there's a workaround I came up with. Using the screen recorder, make a short video where you scroll down the notifications bar. Once the notification you want to screencap is in frame, end the recording, play the video, pause it, and then take a screenshot.

You just have press and hold volume down and home key for some time

This isn't an answer. When I take a screenshot, I press the power button on my phone, then a menu pops up where I can choose to restart or make a screenshot. When this menu appears, the dropdown disappears.

@SPRBRN You have to press the power button and the volume down button at the same time. Then the menu should not appear. If it still appears the device manufacturer has destroyed the screenshot function, because on a AOSP device it works.

Confirm this works on my Google Pixel.

Works on Google Pixel Android 14

How to link an android device (or its account) in a restricted way to my primary google account?
I have an Android powered car multimedia unit that I would like to link somehow to my google's account, so I could send locations from Google maps directly from my PC by clicking the "Send to your phone" button on the location description pane shown in the Google Maps.
At the same time I don't want this device to be logged into this account to prevent any potential data leaks.
Switching between accounts on a PC is not a convenient option.
Is this achievable?

You can send locations not only to your own account but also to friends (or the Google account of your car).

@Robert, I believe you meant "Share" button. I edited the question to be more specific.

"At the same time I don't want this device to be logged into this account to prevent any potential data leaks." - This prevents what you are trying to do, in order to make the Send to your phone option work your Google account must be on the device, you can't just "link" a device to it, you could potentially add the Google account and do not sync any information except Maps although I don't know if that would work.

"Send to a friend" or "Send to your phone" - if it works it does not matter - have you tried it? Anyway you have to use multiple accounts as a Google account on Android can't be limited to just Google Maps.

@Robert, then how to link the device to account so it has no access to all data in the account, uses another password and it appears in the list of your phones?

I wrote clearly multiple accounts not one account. What you want is not possible.

How to delete downloaded files on Android TV
I have a Sony Bravia TV with Android.
When trying to install a new app from the Play store it says I have to free up some space, as my storage is full.
When checking storage in the settings, it says the cca 5.5GB are in the Downloads folder.
But I have no option to delete it, as there is nothing like a file manager.
I also cannot download any file manager, or cleaner etc. as it won't install anything, cause the storage is full.
Any ideas how to solve this?

Although there seemed to be enough space (0.9GB) to install a small file manager app (about 30MB), I had to:
- clear caches from several apps
- deleting stored data from several apps
- uninstall some default app updates
After that I got about 1.6GB of free space, and just then it allowed me to install a File manager, where I was able to browse to the Download folder and remove unnecessary data.
I don't think this is a real solution, there must be another way, but this was the way that worked for me.

Navigate to settings -> Storage then clear the cache it may give you save space to install any of the file manager and delete the files which are not needed.

There is almost 1GB free space but it still says there is no space to download an app

Nexus 5x Won't Turn On
My Nexus 5x started bootloading but now it won't turn on at all. I noticed the battery was bulging so I replaced it with a new battery I bought on Amazon. I charged it all night, but it still won't turn on. I've tried different key combinations and holding them for various times, still nothing. I plugged it into my computer, nothing. I installed ADB, and it didn't list my device when I typed adb devices
(I have not been able to get it into fastboot mode. If I had been able to, this question would not exist)
Is there any way to salvage my phone? If so, please help!
EDIT: There has been no indication of anything happening since the changing of the battery. i.e. no lights, no indication of charging, nothing at all.

Have you tried booting it to fastboot mode? (Press and hold the Power and Volume Down until the fastboot screen appears)

@IiroP, did you even read his question?

You say you charged it all night. Was there any indication that it was in fact charging?

I think the battery is dead (no charge), try changing it outside of the phone (check YouTube videos) then place it back to the phone, should power on now. ADB will never work on a phone that is not fully booted to android or in recovery mode. Try fastboot devices instead

@SiXandSeven8ths Well, he didn't mention exactly what key combinations he had tried. And I have once succeeded at booting phone to fastboot when it seemed to be dead.

Your current phone state is bricked, You have two options

You have to flash official firmware using PC (In your case, your phone isn't even getting detected. You may need to install all drivers such as adb, properly and check it once again)
You have to go to authorized Service center to get this issue fixed.If you have warranty make this as first priority.

Is it a good idea to give my screen lock PIN to an app?
My online bank created an app which can be used to generate TANs or be used as second authentication factor. For the setup it asks for the screen lock PIN which I've never seen before and seems like a bad idea (the equivalent of running an application not only with sudo, but entering the sudoers password into the application on Linux which I'd never do and alert the distributor of the application about potential malware).
Is this comparsion approximately accurate? And thus the use discouraged, maybe even requiring to take the app down? I could ask the app author, but they'll likely provide a biased argumentation.
I verified with the bank's customer service that it requires the screen lock PIN.
I'm using Lineage OS 14 based on Android 7.1.2 with Google Apps installed.

AFAIK the app should not be able to use this pin as it can only be used on the lock screen which the app can't access.The only usage I could think of is to test for complexity and therefore determine if your device has been secured or not.

I'd tell the bank that's a bad idea. IMHO your comparison fits. To determine whether the screen is locked or not, there are APIs that can be used by the app ("Keyguard"). I see no reason why an app should know the device lock pin or password. And I'd never trust an app which accesses the Internet with my passwords. But then, I'd neither do banking on my mobile device.

How do I view Google Camera's motion photos on my Windows PC?
I can download the JPGs from my DCIM folder in my Pixel 2 and I know that the video is encoded inside the JPG, but I don't know what image viewer I can use to see the motion.
I usually use Irfanview, but I haven't yet been able to find out how to make it show the motion. And I haven't found anyone talking about how to do it.
Does anyone know?

I did some experimenting based on the answer by James Henstridge and came up with a simple PHP script that successfully split every Google Camera's motion photo I threw at it.
2022-01-24 - Code has been updated. See the edit at the bottom of this post.  I'm leaving the old code here to avoid any confusion.
<?php

  $src_arg = $argv[1];
  $src_dir = realpath(pathinfo($src_arg, PATHINFO_DIRNAME));

  echo "Scanning for files...\n";

  foreach (glob($src_arg) as $src) {

    $file = realpath($src);

    if (!is_dir($file) && in_array(strtoupper(pathinfo($file, PATHINFO_EXTENSION)), ["JPEG", "JPG"])) {

      echo "\tProcessing: " . $file . "\n";

      $filesize = filesize($file);
      echo "\t\tFile size: " . $filesize . "\n";

      $handle = fopen($file, "rb");
      $data = fread($handle, $filesize);
      fclose($handle);

      $eoi_pos = strpos($data, "\xFF\xD9\x00\x00\x00\x18");
      echo "\t\tEOI segment position: " . $eoi_pos . "\n";

      if ($eoi_pos !== FALSE) {
        $output_base = $src_dir . DIRECTORY_SEPARATOR . pathinfo($file, PATHINFO_FILENAME);
        echo "\t\tSaving photo...\n";
        file_put_contents($output_base . "_photo.jpg", substr($data, 0, $eoi_pos + 2));
        echo "\t\tSaving video...\n";
        file_put_contents($output_base . "_video.mp4", substr($data, $eoi_pos + 2));
      } else {
        echo "\t\tSKIPPING - File does not appear to be a Google motion photo.\n";
      }

    }

  }

  echo "Done.\n";

?>

It should work on Windows and Linux.  You just pass a path as the first argument and it will split any files that it believes are motion photos.  You can use wildcards.  It's non-destructive - the source file(s) are not deleted.
Some example uses:
php google_motion_photo_splitter.php c:\test\file.jpg
php google_motion_photo_splitter.php c:\test\*.jpg
php google_motion_photo_splitter.php c:\test\*

2022-01-24
As j3App mentioned in their answer, at some point, Google decided to add debug data between the JPG and MP4 in some cases.  At the end of 2021, I also began seeing other variations (MP4s with varying start bytes - ex: 0000001C instead of 00000018, extra JPG EOI segments earlier in the image near XMP tags, etc).  Anyway, I modified the code to search for the MP4 header first and then work backward to find the JPG EOI segment.  It's worked on all variations I encountered.  Here is the updated code:
<?php

$src_arg = $argv[1];
$src_dir = realpath(pathinfo($src_arg, PATHINFO_DIRNAME));

echo "Scanning for files...\n";

foreach (glob($src_arg) as $src) {

  $file = realpath($src);

  if (!is_dir($file) && in_array(strtoupper(pathinfo($file, PATHINFO_EXTENSION)), ["JPEG", "JPG"])) {

    echo "\tProcessing: " . $file . "\n";

    $filesize = filesize($file);
    echo "\t\tFile size: " . $filesize . "\n";

    $handle = fopen($file, "rb");
    $data = fread($handle, $filesize);
    fclose($handle);

    $mp4_start_pos = strpos($data, "ftyp");

    if ($mp4_start_pos !== FALSE) {
      $mp4_start_pos -= 4; # the real beginning of the mp4 starts 4 bytes before "ftyp"

      $jpg_end_pos = strrpos(substr($data, 0, $mp4_start_pos), "\xFF\xD9");

      if ($jpg_end_pos !== FALSE) {
        $jpg_end_pos += 2; # account for the length of the search string

        $output_base = $src_dir . DIRECTORY_SEPARATOR . pathinfo($file, PATHINFO_FILENAME);
        echo "\t\tSaving photo...\n";
        file_put_contents($output_base . "_photo.jpg", substr($data, 0, $jpg_end_pos));
        echo "\t\tSaving video...\n";
        file_put_contents($output_base . "_video.mp4", substr($data, $mp4_start_pos));

      } else {
        echo "\t\tSKIPPING - File appears to contain an MP4 but the no valid JPG EOI segment could be found.\n";
      }

    } else {
      echo "\t\tSKIPPING - File does not appear to be a Google motion photo.\n";
    }

  }

}

echo "Done.\n";

?>

Thanks for a good solution. Since my Pixel 4a 5g addes debug info between the photo and the video, I had to make some small adjustments to your solution (see my answer below)

I haven't seen any software to view them other than on the Google Photos website.  I was curious about this so started pulling apart one of the photos from my phone, and here's what I found:

The image file appears to be a standard JPEG image, but continues on after the End of Image segment (0xFF 0xD9).
exiftool reports unrecognised MakerNotes.  I suspect this custom metadata identifies the file as a motion photo.
If transfer all the data after the EOI segment to a separate file, you'll have a standard MPEG-4 container.  I got a GStreamer crash when trying to play it, but ffmpeg seems to be able to handle it and displayed the following metadata:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'foo.mp4':

So, that's a 1.87 second H.264 video with resolution 1024x768, which seems to roughly match up with what I see from Google's apps/website (a drop in resolution and change in aspect ratio).

I know it isn't a complete solution, but it might be enough to get started on a tool to extract the videos.

Although the question is for Windows, I think it's appropriate to post my script to play it from command line on Linux here:

        ARGS+=($i)
    else
        FOUND=1

        T=`mktemp`

        ARGS+=("$T")
        dd if="$i" skip=$((S-O)) iflag=skip_bytes of="$T" 2> /dev/null &
        TOKILL+=($!)
        TORM+=("$T")
    fi
done

if [[ $FOUND == 0 ]]; then
    echo "EXIF tag wasn't detected in specified files. Maybe exiftool does not work?" >&2
fi

mpv "${ARGS[@]}"

Maybe it can be used on Windows as well, with enough Mingw/Cygwin hackery.

There's also Motion-Photo-Viewer. Can either be self hosted or used online to play a single *.MP.jpg (and extract the mp4 through right-click-save-as.
You do not need a Web Server, so cloning the project and opening index.html will suffice.

I tried out the answer from Kory - thanks Kory. Since my Pixel 4a 5G adds a significant amount of debug info between the jpg and the mp4, my extracted mp4's didn't play.
So I had to add a little bit of extra functionality to Kory's solution

Thanks for posting this.  I've also seen this as well as some other new variations.  I updated my original post to work in a way that will hopefully be able to continue working with any future changes Google decides to make.

If you have already downloaded the jpg and MP files to your PC, all you need to do is edit the extension. Change it from filename.MP to filename.MP4 or .MPG and play with any media player like VLC, or import into any video editor like Premiere or EDIUS

I am not a fan of the solutions I have found so far, so I created my own Motion Photo Utility /exporter. https://www.3d-i.com/motionphotoutility/ it is free, closed source (for now), in alpha, and works on most platforms.  It does a lot more validation, meta reading, update meta tags and detects some malformations… See website for more.
All the solutions I have looked at so far seem to follow the pattern of read whole motion photo jpeg file ~3,000,000 bytes long and look for EOI marker of jpeg anywhere in the file aka 0xffd9. Take a hacksaw and chop it there, and assume all is okay.  You might get lucky and the corrupt info can be read by some robust software.
Warning the following is a verbose explanation, it may put some of you to sleep!
These new jpeg files are complex.  Old jpeg version has 11 tags describe everything: https://docs.fileformat.com/image/jpeg/
The simplest jpeg parsers generally read to tag/marker, read var = bytes[length] associated with tag.  Then consume the next var length of bytes in some defined manner.  At the end of that data block a tag is EXPECTED 0xFFXX, if it is not there then throw an exception…. But that is also not enough.
Today jpeg file format continues to undergo changes adding meta data Exif, XMP… In the last few decades, every camera company has had some say in putting all kinds of interesting data into these files. From shoving thumbnails, videos, gps , orientation …, often for good reason. Exif meta data has several hundred tags, when that was not enough XMP was added, which has unrestricted length for describing imbedded data.
Some of these programs completely violate the rules, forgetting to represent tags etc, or have incorrect information.
Those poor software engineers that write your media players etc (vlc/browser), over the last decades, have to navigate around the changes and display what they can.  The problem is they don’t know what the intent for a lot of the imbedded meta/data, and it is often just dropped.  Case in point, open up a copy of an android motion photo on windows, click the favorite icon (heart).  Observe the file size before and after, it is about half the size.  Windows will delete content (including video), add some of its own meta tags and largely keep existing meta that describe the very data that was deleted. Aka it makes a mess.  In my test VLC player (which is incredibly robust) will play motion photo as a video, but only render a still image.

An updated Motion Photo Utility to support newer android Motion Photos.  The previous version over cautiously did not correctly recognize newer motion photos.

I'm developing a motion photo viewer for Windows 10/11, compatible with various motion photo formats from Google and Samsung, including JPG and HEIC.
It also allows exporting of video as MP4 and still frames as JPG.
Install from Windows Store:  https://www.microsoft.com/store/apps/9NMBBHZ33KLM

Please let me know if you have any issues. Thanks!

DeadSystemException causing Google Pixel power cycling?
I am getting this error when my phone is power cycling randomly without my control. See below for previous error logs.

Back story:
I bought a Google Pixel online recently, and I've had an issue with it power cycling randomly.
I've followed numerous online help and suggestions from sites such as here. Here's my experience

The phone will operate normally for a week or so, then go into waves of power cycling very frequently
Safe mode stops the power cycling
A factory reset will cease the power cycling, I've done this once and assumed it had fixed it, but the issue has returned today.

I've done some android app development before so I booted up android studio to see if the debug logs could reveal the cause of this issue.
Here's the logcat debug logs pastebin.

Block phone calls which are not saved on mobile
I have a Samsung Galaxy S6. I  want to block all calls which are not saved in my contact list: the phone should not ring, but the blocked call should be recorded in the call history so I can call back if I wish.
I have found many apps but they reject calls after ringing once. So strangers think he/has not recieved call and cut.
Is there any help or setting in Android?

I'm not sure if it's possible to supress the ring without root powers. You could try Block Calls, which is a privacy-friendly call blocker app that has the option to block calls from numbers which are not in your contact list. They write "It is known that some devices vibrate or ring a few seconds before the app manage to hang up the call", so this might be device specific.

Thanks for link. I've install extension.it just reject call not block

How do you assume blocking should work if not by rejecting? The only alternative I know of would be simply suppressing the ring tone (i.e. let it continue ringing, but soundlessly, until the caller hangs up). That could possibly be achieved using some automation app (incoming call › not in contacts › ring volume=0; call finished › restore ring volume).

I want it shoul work like when stranger call it turns flight mode

Then you'll have to look into automation. No such setting exists in Android itself, and I'm not aware of any app acting like that either.

Does this answer your question? Block calls for everyone except for contacts

Actually there is. Download 360 antivirus. In the its security menu you can block all unknown numbers, fortunately there's a history of the caller and the number of times the number has called. If you are having issues finding it, you can reach out to me.

Can you mention link please?

No longer in Playstore AFAIK. And comes with a bunch of trackers (7 ad modules, 4 analytic modules). You certainly wouldn't want that. Apart from that, it will do the very same: rejecting calls.

No way to clear the Monthly Data Limit on Huawei Mate 10 Lite, Android 7.0, EMUI 5.1
So, I'm in my 3rd month of ownership of my first (and last) Huawei smartphone and I have discovered yet another strange family of issues.
I have a 20GB monthly data limit from work so I rarely check my data usage. But I had a few extra charges on my last bill so I decided to check it out. (First time on this phone)
The first shock was that there was no Sum of the usage, just a graph with the daily peaks and that's it. So if it was say the 30th, then you would have to add-up 30 days worth of data to find out how much you have left. What a joke:

Anyway, so I figure that I should add a data limit and maybe that will Sum-up my usage. So I tap on the gear icon on the top right, then on Monthly Data Limit and enter 18GB. Voila, my total appeared:

From here on, the story gets even stranger.
I tapped on the pencil icon and for some strange, inexplicable reason, you can actually edit your usage. What exactly is the point of that??? So I enter a number and tap on OK to see what happens, and now the Used total becomes whatever amount I entered:

So I decided to revert to the ACTUAL total usage and I was confronted with yet another trademarked Huawei irritation. You cannot clear your own usage, you have to enter something in that box, otherwise Save stays disabled:

So as a last resort I thought that I should clear my data limit and be done with all this mess. Sadly I discovered that there is no way of doing that. It seems that once you enable the data limit, you're stuck with one. You can only change the number of MBs or GBs and again like above, you have to enter something in that box otherwise OK is disabled:

I tried Network settings reset but all that does is delete your stored Wi-Fi networks (thanks Huawei) and Bluetooth devices (thanks again !)
Any ideas?

Have you tried to enter a zero ("0") into those fields? If that doesn't work, then an "imaginary limit" of e.g. 200G? And simply put back the original number of your usage (and no, I have no idea why one should edit that)?

@Izzy - that was the 1st thing I tried. Alas, 0 actually means 0. It effectively disables Mobile data right away. Also, you cannot reset the actual data usage, either

OK, so set 500G for the limit. And what do you mean you cannot reset data usage? According to your question text you did exactly that (from 1G to 111M).

Once you've typed your own total. There's no going back to the actual total.

See if this works:

What are you trying to achieve? I see lots of complaints here but I'm not sure what the actual question is.

Clear "phone manager"  app data, it will return limit to "not set"
Works on all huawei phones.

I will accept this as the answer, however it does not only delete the usage settings. That's not your fault though :)

Just clear the Phone Manager's cache and it will go bat to 'not set' if you don't want to clear its data, Setting → Apps and Notifications → Phone Manager → Storage → Clear Cache.

You can reset the settings app. Find Settings app in the apps list and clear data.
To check what’s using your data, go to data usage ranking.
It doesn’t let you see a total unless you set a limit.

Go to settings → apps and notifications → phone manager → storage → clear data
After clear data it will go back to 'not set'

On my P20 Pro it was "Optimizer" instead of Phone Manager.
Settings -> Apps -> Optimizer -> Storage -> Clear Cache

How to reset back Monthly Data Limit to "Not set"
1st Optimizer from the home screen, Optimize it
2nd Go to Settings -> Apps -> Optimizer -> Storage -> Clear Cache & Clear Data, then restart the mobile

Cookie Alert on Android
Is there a way to block eu cookie alert on android?
Tried Adblock browser - no luck. and i am using a cookie alert blocker on PC, which doesn't work on Android.

Have you looked into this? If this is what you are looking for it can be done inside the chrome browser on Android. It's almost at the bottom.

https://mirrorbits.lineageos.org/su/addonsu-15.1-x86-signed.zip

Only the 3d did not give a red error.
So as much of a trivial challenge it may appear to be, I was curious if anyone can point out which mistake I am making in trying to give the device root-access again. Other suggestions are welcome as well!
*Note, this was also the file that allowed me to root it the first time.

As you've already found out, LineageOS has its own, built-in, lightweight SU solution (addonsu), which is the only one supported officially (the team does not adore Magisk/SuperSU).
Note that officially LOS only provides 14.1 builds for your device. Assuming that's the version you're running, using the addonsu for 15.1 you will naturally bump into problems. As indicated in the source, your device is an arm one, so use addonsu-14.1-arm-signed.zip instead.
Magisk/SuperSU are reported by other users to work well enough, but you will need newer packages that work with higher Android versions, and the one you initially used (SuperSU 2.62) isn't enough.

Thank you for your overcomplete answer! And I appreciate the link to the source.  I was curious why the team does not adore Magisk/SuperSu, and I will look into it.

The team doesn't want errors caused by 3rd-party addons - which would be hard to recreate and track down - to pollute their Reddit and bug-reporting platform.

It seems that you had Lineage (im on 14.1 right now & i love this rom), but you wanted, instead, the excitement, unreliability, the Wonder, of 3rd-party root management.
  Yeah, I used to smoke a lotta that, too. JK.  CM/LOS's su is way more stable, predictable, user-friendly, and PRIVATE than most other root-solutions. Seems you weren't aware of the add-on at first, but in the future, Google everything about your device before flashing every file that comes in a zip-format.  Knowing your architecture  is kinda a big deal in the root/modding communities (im curious how the x86 add-on was the least error-throwing on your arm device). You're lucky that root access was the only issue you were fighting.  I can laugh at you because I've been there, done that.  You did right by asking, though.  Live and learn.

Thank you for your elaboration Rick, it is a good reminder to check the architectures and versions of my hardware and software before I flash anything on it!

Sony Xperia Z3 D6446 Touchscreen not working right on bottom
My xperia touchscreen got physically broken. I got it to a "tech service" so they promised to use an original piece and change the old damaged display with a new display.
After they changed (many other hardware things like camera button and gsm antenna where damaged), the touchscreen aparently works ok, but, I noticed that, until I tap closer to the bottom of the screen, my taps get misplaced. I can verify it with the developer options.
I tried changing the resolution, density and overscan via adb shell with multiple values, but the effect is almost the same, it seems the installed  display doesn't have the right behavior.
I've tried like 20+ touchscreen calibrator applications (like 3 different languages) to solve this problem, and still persists.
I restored to factory, installed custom external ROMs, even installed ISP custom ROMs and nothing worked.
I've run the test for the touchscreen and I can use all the screen without a lose.
Hope someone can lead me to a possible solution, maybe a way I can play with those 3 values so I can "emulate" the correct position of my taps. Ideally, a way to "not enlarge my taps" while I get closer to the botttom of the screen.

It simply sounds like you need another hardware replacement...

Well, I tried all the possible solutions via software, and finally I've decided to throw it at technicians face for breaking the touchscreen, there was no other option. Thanks.

SIM IccId - logged anywhere?
Is there anywhere I can find historical traces of the IccId? By that I mean, something to indicate the identity of the sim card at some point back in time.
Ideally, this would be as far back as possible. Any "recorded" instance of IccId would be of relevance - system logs, attributes in SMS or call log - anything, really.
I doubt the background is relevant, but if anyone is curious:
In the peculiar case of my carrier disagreeing with what my SIM card's IccId is (and as a consequence, I assume, which physical sim card I actually possess) I've experienced the following:

I read the IccId off of the physical card, let's call this number 123.
When I ask my carrier for the PUK code, the response is an IccId (let's call it 456) and a PUK. 456 is different from 123 (very different - it's not a typo or anything) and the PUK (naturally) doesn't work on my sim.
When I say that IccId 456 is not the number that appears on my sim, seemingly nobody is able to figure out why they're showing an IccId for me that isn't the sim that I physically possess.
I've spoken to 3rd level techs and they say that IccId 123 was produced a year ago, but registered to the network only a week ago (despite having been in my phone for well over a year)... but is not and has never been in "actual use".
They also say that they see activity from IccId 456 consistent with the activity I've relayed to them.

I've used my phone without significant issue (the only issue being that I was unable to get a form of mobile banking authorization based on a Sim Toolkit-equivalent, and I'm now guessing that this must be significantly related to the IccId disagreement) for the past year, so any notion that my sim card hasn't been in use, or registered prior to a week ago, is empirically untrue.
The phone is a Huawei Honor 8 (FRD-L09, bought in Europe if that matters). It is not rooted so I would prefer non-root approaches (though root approaches are still welcome).

Run Android RPI on Android emulator
I want to run the compiled images of the Android RPI 3 on an Android emulator. I have looked everywhere but I didn't find any way to emulate Raspberry PI and sideload the images.
Is it possible to run Raspberry PI Android image on an emulator or any image of another hardware on an emulator?

Given that emulator is supposed to 'emulate' a AOSP device, what do you mean by I want to run the Compiled images of the Android RPI 3 as there are no HAT or other specialized third part hardware to connect.

What i want to do is to run the compiled Images of RPI3 into android Emulator, how to costumize AVD to run customized rom of a device ?

The Android Emulator uses QEMU as the hypervisor.
While QEMU appears to emulate Raspberry Pi 2 you should read the documentation about ARM support to see if it fits your needs.
Update
Physical devices have different driver configuration than the emulator.
And if you want emulator to have any performance you'll have to use a different CPU architecture (x86 vs ARM). Please reach up on Adding a New Device in the AOSP documentation (note the layers).
I don't know if you could run a binary AOSP image on RPi on QEMU but it would be slow (and still need to configure fastboot etc.), this thread: https://www.raspberrypi.org/magpi/android-raspberry-pi/ leads me to believe that drivers will be the blocking point.
Another thing that is leading me to say what you want is very difficult is that it sounds like you want load almost arbitrary images. This article on XDA about EFIDroid shows what I think you want but is limited to a set of supported Qualcomm Snapdragon devices.

Here is basically what i am interested in, i want to customize QEMU or anrdoid emulator to run any other custom Rom ( system image, ramdisk, kernel...) not necessarily RPI3 but run any other images that i compile using AOSP

If you are already building new AOSP image what is wrong with Running emulator after building Android from source in which case this question is getting off-topic for Android Enthusiasts

i guess i haven't explain my needs very well, the question is basicaly, can i run different images and also load emulator with kernel different than goldfish for testing purpose. for example running LineageOS or other custom rom on the Emulator before flash it in your physical device

I've updated my answer, I'm leaning toward very difficult as you give the examples of (a) a different kernel (b) a different OS. If you want off the shelf solution, I don't believe there is one.

Ok, i have been looking around the the only thing i found is this which is very old: https://forum.xda-developers.com/showthread.php?t=1599005 , that's basically what i want to do or at least be able to do with different device ROM. in the XDA post they load SDK add-on of the Xperia X10 and then use it to load Xperia image and run it on emulator.

I believe it is using the ARM version of the emulator to run your 'image' so back in the Android 2.x days the hardware layout/kernel may have been similar enough.

OK i understand, i will keep looking around maybe i will find another solution.What about building an android emulator based on QEMU source code from the ground up and you can add support for your device ? is that something possible ?

Motorola G4 random no internet via WiFi
When connected to WiFi at home, my Android phone randomly says there is no internet connection with the WiFi and it switches to 4G. There is no notification of this. An exclamation mark will be shown in the WiFi icon. However, reconnecting to the same WiFi solves the problem, until the next moment the WiFi is 'not connected' and that moment can take half a day or just a couple of minutes. The WiFi signal is excellent. It doesn't matter if I connect to 2.4 or 5ghz.
Now this could be a connection with my modem at home (modem is for internet, routers are connected to modem for WiFi), since other android devices (Samsung) do not have that problem. I've also tried to connect to other routers at home, but I get the same problem. I also don't experience the problem at other WiFi connections. AFAIK there is no option to not fallback to 4G when WiFi is not connected. Other than check my modem again, could there be a different approach to solve this problem?

How to send a text message from Skype on Android?
So, I just spent 30 minutes trying to find out where to send a text message (SMS) to a phone number using the latest version of Skype on Android.

Does anyone know if it's still possible to do this or has this feature been removed? Please make sure it applies to this rather new version of Skype for Android.

In the latest version of Skype, you need to follow these steps:

Go to the Calls tab.

Select the dial-pad icon

Type the number you want to send an SMS to.

Type your SMS and send.

The problem is my Skype app does not look like yours. Thanks for trying but that is not going to fly here. If anyone has a working solution for my version of the app (see my original screenshot) then please post an answer to this question.

Well, as you mentioned yours is latest version of skype. so, last I checked, the latest version is 8.24.0.2,which is my version as well and I have shared the screenshots of the same.what version are you using,if this is not what your Skype looks like.

Huawei P20 Pro charging in USB host mode
I'm seeing several related questions here. However, most of them are ancient (as in 2012) and refer to micro USB and maybe the USB-C standards are different with regard to host mode charging.
I'm using my P20 Pro as a tactical flight computer with two connected devices.
The first one is a single row mini usb keyboard and the second a flight vario which sends position and elevation data to the software.
   P20Pro
     |
mini USB-Hub
  /     \
KBD     Vario

What I'm missing in this setup is how to power the phone.
I would need something like this:
   P20Pro
     |\
     | \Portable Power Bank
     |
mini USB-Hub
  /     \
KBD     Vario

This is just some background info. The question could also be How to charge the P20 Pro while a usb keyboard and mouse is connected?
Basically (at least according to Huawei's online chat support) the device supports charging in host mode since their MateDock 2 adapter also charges the phone.
However, the MateDock 2 would be an overkill since I don't need a HDMI/VGA port.
In addition I'm not sure what the MateDock is exactly and if it also redirects non standard USB devices.
Another solution would be wireless charging but the P20 doesn't support this technology.
So what is the the 2018 answer to charging in USB OTG host mode ?

I managed to achieve this (and use an HDMI monitor) by using a USB C Power Delivery hub, and a PD charger. The hub included as well an HDMI output, but it's cheap (around 30€).
I think I used this one here.
I bought two different ones but the second one does not seem to be available anymore on Amazon and the link does not work anymore.
The charger I used is an USB C PD 41W charger from Auckly.

The answer really seems to be the USB Power Delivery (PD) standard. However, I'd love to see a phone with 3 USB ports instead of 3 cameras ;)

Can you link an Andoird phone into your home internet without having to pay for a monthly service?
I have never had a phone before. Can phones do this?
I want an Android phone.
I want it to be able to download stuff from the Google Play store.
I would like it to be able to do this using my existing home internet router, without the need for a further monthly subscription to some phone-based data plan. (I only intend to use this phone from home. I am with Sky Broadband for my home router.)
I would like the phone to be as cheap as possible, about £50 or slightly above. (I want to make sure it is right for me before spending loads of cash.)
I would like it to be able to play simple games like checkers, chess etc.
I live in the UK, if that is important.

I bet your home router supports WiFi. It's the same wireless networking technology that laptops use to connect to the Internet. Android devices have WiFi too, you can enable it and connect to your router to use its Internet connection.

The simple answer is yes.
With no service contract, or cellular service at all.
Not only can you connect it to WiFi, (you usually need a Gmail account)
You can get free text messaging via Google voice or freedom pop from the play store.
And if you feel like getting frisky you could dabble with Asterisk and use the jabber/gtalk modules to make voice calls via VOIP through the Google voice service, or any other VOIP provider. (Using a SIP soft client such as csipsimple)

When turned on wi -fi something unknown uses data suddenly
When i turned on wi-fi something unknown uses data rapidly..I use android version 4.4.2 ..Can't find anything that uses data, I did a virus scan, and removed all unknown apps also,and there are just a few apps,I've installed..Does it use by the OS or other thing,I tried to run only with mobile data but some apps ask for wi-fi..How can stop this unknown data usage, without turning off wi-fi..

Go to settings -> Wireless & networks -> Data usage. Here you can check detailed data used by each app. Did you check the statics there?

yes now i checked it..According to that these apps use the data..Android os,downloads,media storage ,download manager...Then i cleared cash and data of those apps, but they still use data,don't know any reason..OS is also up to date..

Yes i found the answer..
settings-> about phone -> tap build number for few times(that enables developer tools..)
settings -> developer tools -> background processes limit -> no background process
that's all..Now data usage while phone is idle is 0..

com.qualcomm.embms keeps popping up every few minutes
In Lenovo Phab, a message : "Unfortunately, com.qualcomm.embms has stopped." keeps popping up exactly twice every few minutes, to which I've to click 'OK' every time.
I've tried force stopping it from the settings manually but it's still going on. I've scanned the device with McAfee but there are no threats. But a Quadrooter scan tells me I've the following vulnerability : (CVE-2016-2504).
Is it possibly popping up because of that? Or is it just a bug? What should I do to make it stop popping up? Help would be appreciated.

A new widespread vulnerability that affects millions of Android devices around the world could allow hackers to read your SMS text messages, phone records, and perform any capabilities the radio allows.
This hack involves the netd daemon, which is the network interface in Android. The problem arose when Qualcomm released new Application Program Interfaces (APIs) as part of the network_manager system service, which also involved the netd daemon. These APIs allowed additional tethering capabilities.This vulnerability is labeled as CVE-2016-2060 with a medium risk.
Devices ranging from Gingerbread to Lollipop are likely affected. So, if you can upgrade your android that would be the best option.
Also, The FireEye Mobile Security app will detect the Qualcomm vulnerability, but it’s only for enterprise customers. If you have a corporate phone, check with your administrator to find out if your company subscribes to the service.
The good news is that FireEye has been monitoring the use of the API, and hasn’t found any occurrences of it being exploited. However, that could change as hackers learn of the flaw.
Looking at the big picture, it’s still more unlikely than likely that you will fall victim to an attack.
You can read more about this issue in this blog.

I deleted my Gmail account but I keep recieving the notification "Account Action Required" but I can't access the account since it's already deleted
I deleted my Gmail account but I keep recieving the notification "Account Action Required" but I can't access the account since it's already deleted. By the way I used my phone to delete the account. How can I remove the notification? I tried everything.

For Honor Mobile :
Setting->Accounts->Google->select the account and remove

Even if you deleted the account on Google, your phone is still trying to log into that account, and giving you the notification to tell you it's not working. You need to remove the account from your phone too. From the Settings app, scroll down to the Personal section and choose Accounts. Then choose Google from the list, and from the three-dots overflow menu, choose Remove account. Some manufacturers move around the settings on their phones, so while the instructions above are fine for stock Android, they might not be quite right for your phone model.
Note that apps you purchase on Google Play are tied to your Google account, so it's not usually a good idea to delete the Google account that's the main account on your phone. You'd want to follow these instructions if you've added a second account, such as a work email, and it's been deleted or disabled.

Deleted thumbnail file but no space was freed
I'm using Sony Xperia Z3 and used File Commander to browse and found that I kept running out of space because of a 4GB thumbnail/preview file/folder that grows rather quickly.
I tried deleting the folder, but after deleting the folder, I saw that no space was freed and it was still there. So I tried moving the folder to my SD card which resulted in 4GB of space taken up on my SD card and no space freed.
I don't think I can find the thumbnail preview folder anymore, but I think new files are building up because I'm running out of space again.
Does anyone know what's going on?.

The .thumbnails folder has a file of the format .thumbdata4* whose size is shown to be really big usually. But in reality, it's not a big file and it's size is shown as such is because it's not a normal file.
It's a sparse file and its real size can be seen using du command from a terminal emulator. ls shows the file size from it's metadata like most tools do and it'll be a big number.
On my phone, it looks like this:
/storage/emulated/0/DCIM/.thumbnails $ du -h .thumbdata4--1967290299
172K    .thumbdata4--1967290299

/storage/emulated/0/DCIM/.thumbnails $ ls -alh .thumbdata4--1967290299
-rw-rw---- 1 root sdcard_rw 11G 2020-07-30 19:18 .thumbdata4--1967290299

So it's actually a small file, and you don't have to worry about it's size.
See the size difference. ls shows size to be 11GB while du shows it to be only 172KB.

Thumbnail folder is automatically created by android. It helps android to open pictures from gallery in a faster way. Even if you delete the folder, android keeps on recreating it.
Although there is a work around it. You can create a text file and save it with extension .thumbnail. Now replace .thumbnail folder with .thumbnail file.

It should be a comment but It seems I have enough reputation yet.
I have no knowledge how the space is taken, but echo -en > .thumbnailsX-xxx (*Anyone trying this should do it at your own risk. *) DOES set the size to zero and total free partition space LOOKS increased, while simply deleting files can't.
An educated guess would be these files are located somewhere else in the filesystem tree and linked here but that is just a guess.
I came here looking for a way to locate the the deleted files and empty them, if my guess were true.    If not true(say sparse file), I would be grateful if anyone can explain in detail.

Hi, looks like you actually have enough reputation to comment since the beginning due to the association bonus rep (+100). However, this looks like a proper answer (whether correct or not), so I don't think it should be posted as a comment instead.

Connect OnePlus One through adb keep disconnecting
I'm trying to switch my OnePlus One from CyanogenMod to LineageOS, and to do so I need to use adb adn fastboot. I use Fedora 28 as OS on my PC, with the latest Gnome as DE.
The usual "data" connection works fine, meaning that I can access my phone's internal storage and copy files from/to that memory. Trying to use adb, I I changed the USB mode to "charge" and enabled adb from the Developers Options menu under Settings.
As soon as I connect my phone to the PC, it looks like it is stuck in a loop of connecting and disconnecting the device. I don't see any prompt on my phone regarding the adb connection, and dmesg shows the following output:
new high-speed USB device number 31 using xhci_hcd
usb 3-2: New USB device found, idVendor=05c6, idProduct=6765, bcdDevice= 2.32
usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-2: Product: A0001

usb 3-2: reset high-speed USB device number 31 using xhci_hcd
usb 3-2: device firmware changed
usb 3-2: USB disconnect, device number 31

where the device number starts with 1 and goes up, and up, and up, until I physically disconnect the phone.
adb start-server (executed as root) shows no error whatsoever, but adb devices shows nothing (both as root and as regular user (not sudo)).
What's happening here?

After a few digging, I found out that the problem was due to an old version of abd in the Fedora's repository. Downloadting the latest platform-tools from the website fixed the problem.

Samsung Galaxy s7 is an LTE device and not VoLTE. But if you still want to make voice calls over LTE, you can download jio 4G voice app from https://www.jio.com/en-in/apps/jio-4g-voice  .
It is very user friendly app,still in its beta phase. But it lets you enjoy all the features of VoLTE while you are in LTE.

Processes involved to update an app
We run Android devices in KIOSK mode, and want users to able to update apps directly. Nothing happens when "Update" is clicked, it seems we need to whitelist / authorize some additional processes in KIOSK mode.
Could you please clarify what are the Android processes involved when an app is upgraded on a device ?
Thank you for your help

Did you blacklist Package Installer?

No it's whitelisted (com.android.packageinstaller)

Are you updating your apps via the Play Store?

This is through the Mobile Iron app (Mobile@Work / Apps@Work) which is whitelisted in KIOSK mode

How do I log in to Android Messages for Web without my phone?
I recently discovered the Android Messages for Web service! My immediate thought was, awesome! If I forget my phone at home, I can still text when I'm at work. In an emergency, I could send a text message using a friend's computer.
However, when I logged in, I discovered that I needed to use my phone to log in by scanning a QR code on my computer screen. I'm afraid that this defeats the purpose for me.
(I'm aware that it has a "remember me on this computer" feature so it will work in some cases when I don't have my phone with me, as long as I've recently logged in on that computer with this option enabled. But this is not all computers at all times, so it defeats the "in case of emergency" situation.)
Is there any way to authenticate myself to Android Messages for Web without having my phone with me?

No. This appears to be Google's intended purpose.

What happens if I disable Google app?
If I disable Google app (which came preinstalled on my phone and which I don't use) will that have an effect on other apps by Google like Google Maps or Gmail?
I want to disable it for privacy reasons but I don't want other apps to be affected.

Causes bootloop in a Nexus phone.

No, it won't have any affect on other Google apps. I have it disabled in my phone.
Here are the things I can't use anymore:

Search widget at homescreen. I have removed it anyways.
Google assistant.

I've basically never missed anything with the Google app disabled. Maps, Gmail, contacts sync and everything else works as they should. I don't see them having any connection with Google app.
However there will be issues if you disable Google Play Services app.

Today I found out that disabling the Google app not only removes the Search widget, but some others as well. I.e. At a glance (calendar and weather), Feed (not sure what this is, maybe an older version of At a glance) and Google sound search

Unable to flash custom recovery in Samsung j1 ace
I am trying to use the TWRP custom recovery on my device but am unable to do so.
First I made sure I had the latest ADB and Samsung drivers. Downloaded the TWRP .tar file which is compatible( I think so, its not the exact model number, which is SM-J110H) with my device. Then I proceeded to run Odin, connect the phone to the PC using an usb cable, and put the phone in download mode.
Everything was working alright until I 'flashed'(Put the TWRP file in AP, clicked Start, the log showed 'All threads completed. (succeed 1 / failed 0)
').
 After that, my phone rebooted. Now, whenever I try to go to recovery mode or boot my phone, it just hangs and a red exclamation mark is shown at the top left.
I have fixed it by flashing the stock firmware but would like to know why it doesnt work.
Any help would be appreciated.
Many thanks.

My first thought is that your recovery image (.tar file) is either uncompatible or corrupted.
To prevent this :

Double-check that your recovery image is compatible with your exact
phone model. If it's not, ask the developer about it.
Check the control sum (md5sum, sha256sum, etc.) of your file once downloaded. If it's different from the sum on the website, download
it again (from another miror if possible).

You may also use Heimdall instead of Odin to flash your recovery image : https://www.glassechidna.com.au/heimdall/

Searches and locations I didn't do and never went to
How is my phone in Google search showing I searched places that I never searched and shows I went to locations where I have never been? There are local places but not me. I changed my password several times and always have my Samsung Android phone on me.

How to disable auto update Google Play Store and Google Play Service
My phone broken WiFi (couldn't scan WiFi around). So, I have to use phone data. However, I'm having problems with two apps: Google Play Store and Google Play Services usually updating, consume a lot of phone memory, and use more and more network data (I pay a lot of money for them).
I have gone to "Settings" and chose "Disable auto update" but it just didn't update the other apps but it kept updating the two apps themselves.
So, I hope people can give me some solutions to solve this problem okay?

Having a similar issue with one of my devices, but my workaround is using a firewall application to disable internet access for these apps.

I agree with Xavier. This works as long as you don't open an app requiring Play Services, such as Maps, in which case you would have to permit internet access to Play Services as well to use the former app's full functionality and thus have to bear the burden of updates too.

Android phone display stuck and restart not working
My Android phone's display is stuck and none of the three buttons volume up/down and lock are working. I tried calling myself from the Android device manager, which didn't work.
I connected the phone to my laptop, it shows up connected as an MTP device.But, when it try adb devices, it doesn't show up.
What can I do to regain control of my phone?
For now I am just waiting until the battery is empty, so that I can restart it by plugging into a power source. Is there a better way?

Press and hold Volume Down button and Power buttons together for a 10 seconds and your mobile phone should restart.

oh wow, that worked. I has tried that but not long enough I guess. I had tried all the possible combinations of those buttons for at least 5-6 seconds. Thanks, it worked

This was answered in the comments by @Sandeep , but I hate unanswered questions, so:
Try a Hard Reset: Hard Reset essentially forces your phone (or any device, for that matter) to reset regardless of what it was doing or where it was stuck. It's the first thing you should try if all else has failed and you need your device to work.
Hard Resets, at least consumer devices with limited buttons, is usually done by holding the power off button for longer with another key.
For Android, it's usually the power button along with the Volume/Up Down Button for about 10 seconds or more. For iPhones, it's usually the Home Button and the Power button. For PC/MACs, just holding the power button for a long time can cause a force shut down.

well i was trying to do that only, just that I was not doing it for 10s long

Instagram Login Error - sorry there was a problem with your request instagram
Instagram Login Error -

What is the reason for receiving this error message in the Instagram?

I had the same problem few weeks ago and i figured two ways to get over it.

This option is for people who have a different phone in handy. You just have to login to your instagram using a different phone(and the irony is that it allows you to login there). Then you link your instagram with facebook. Logout from instagram and then log back in to instagram using your original phone with facebook.

Now, if you don't have another phone with you or you don't have a facebook account, you can try option 2.

This option requires you to download an app called parallel space. this app basically clones all the apps present on your device. And then using this app you can successfully login to your instagram.

Lineage OS -- Phone still spying on me?
I switched from Android to Lineage OS, and I installed the most basic Gapps package possible, called 'pico', to get the bare minimum requirement for the Google Play store. I then manually disabled Google Play services. If I want to get to the Play store, I have to manually re-enable this.
Recently, I was in the car with my wife and son, and I mentioned that I miss the funny vines that were produced when vine.co was still active. Then, when I got home, I connected to wi-fi, went to Youtube.com through a mobile browser (I don't have the app installed), and the homepage was showing my 'funny vine compilations'. I was not searching for vines before this.
Then, today, I was telling my wife that we need a better vaccum cleaner, and that we should order a Dyson on Amazon. An hour later, I went to Amazon.com on my phone and the home page showed a deal on Dyson vaccum cleaners.
The reason I went through the trouble of putting a custom ROM on my phone was that I didn't want my phone listening to me. I'm not logged into my Youtube or Amazon accounts on my phone, and I didn't search for these things. I suppose it could be a coincidence, but I highly doubt it.
So my questions are: how is my phone spying on me? And how can I prevent this?

Hard to tell without knowing what apps you have installed. I wonder why you installed GApps at all (to access Playstore, you could also use Yalp or Aurora, and for other GServices there's always microG as replacement). A custom ROM doesn't necessarily protect you against "snooping apps".

Interesting, I've never experienced such behavior with stock (or manufacturer modified) Android. There must be something other than Android listening to you.

Had this happen to me recently with LOS 15.1. Still investigating, but I currently suspect Google Framework Services' microphone permission, because I don't have other well-known culprits installed like the Facebook app. I've seen people say the Google services also listen in through the microphone, albeit the stories I found this in were from many years ago. (Won't put this in an Answer until I'm closer to being sure.)

Can I setup an Android 7 box play all movis in a usb drive upon start and infinite loop through them?
I bought an Android 7.1 box and I like to use it for a marketing event.
The idea is to have a few mp4 files in a usb drive and setup the android box such that it infinitely loops through all the movies in the USB drive upon start.
Is that possible?
Can I add a few images to the loop as well?
