Android 4.4.2 crashes while screen is off - Android Q&A, Help & Troubleshooting

Since Thursday, my mobile sometimes crashes (it restarts, and No Frills CPU-Control is telling me, that the reboot wasn't normal), when beeing in my pocket for a few minutes. When it happened a few times, I downgraded all Applications which I installed since Wednesday, but nothing helped. I didn't made any bigger chances to my mobile.
When checking SuperSU logs, I saw, that Greenify mght be the problem, so I blocked root access for the app. This didn't helped, but when I disabled the app, the crashes stopped. :good:
But today, it happened again. Are there any logs in Android, where you can view the reason for the crash.?

Does Android not safe any crashing logs? I can't really believe this

[HELP] Apps constantly crashing and preventing use

Hi guys,
I have had the Galaxy S2 for just over a month now
I have not installed any custom roms. I've just updated it once and then rooted it after that.
I have had very little problems with the phone so far. It would rebooted by itself 2 to 3 times but it worked just fine.
The problem began when I turned my phone off. I can't remember why but I did and when I turned it on again apps would be crashing left right and center.
I pretty much have no access to anything since the crashes occur constantly.
It's the normal crash notification you see on the phone
ie. Sorry! Application xxx (in process xxxx) is not responding
ex.
xxx - TwLauncher
xxxx - com.sec.android.app.twlauncher
Pretty much all the applications that run at startup (including widgets) crash
I would click on "Force close" to get rid of the pop ups but
Logsprovider and Calendar Storage continue to crash making it impossible to use that phone
Any help or thoughts would be greatly appreciated!!
Thank you guys
I would try going into recovery mode and doing a factory reset, should sort it out.

is there no other way? i was hoping there was a way that fixed the problem but also retained my applications and data...

gps crashes phone, problems logging crash

Thank you for reading. I feel really stuck and though I've tried cannot solve this on my own.
The Problem:
When my phone crashes, the logcat apps that are happily recording the events get force closed along with it, and the buffer is lost forever. I seemingly have no way of recording the actual crash event so that I can research the problem.
Possible Solutions, Unfounded:
So I guess what I need is a logcat app that writes the events to file as it's reading (none seem to offer this, only saves manually) or a way to read the internal log after the crash occurs.
Crash Description:
When it crashes, I get a few short successive vibrations, then a lot of lag between a few seconds to a minute, then (if I'm lucky) the screen goes black for a few seconds and then a sort of an instant reboot occurs where I am at the home screen and all the widgets/icons are loading again and all the programs running a moment ago are not open, and any programs normally loading on a startup will start. It always will say the Sim Card has been removed and I must reboot. I lose contacts but not network. Sometimes the phone just freezes without going black and the fast reboot occurs after some minutes or not at all.
Background on what causes the Crash:
As you know, the GPS on the Fascinate and other Galaxy S models have serious issues with accuracy. I have tweaked the internal settings (*#*#3214789650#*#*) myself, without modifying system files (I dont think I ended up going that far) in order to produce better results. I did this months ago and havent changed it since.
The tweaks did not perfect it, so for some apps where accuracy is crucial I temporarily use an app called FakeGPS, which allows me to manually set my location while the app is running. It worked fine. After I updated about 12 apps at once, FakeGPS included, now whenever I run that application the phone crashes as described above.
At first I thought it was just the new version of the App, so I tried a different one that did the same thing. But it also crashes in the same way. I reinstalled both, still crashes.
I am using firmware 2.2. My phone is rooted. I'd be happy to answer any questions.
Really appreciate even just a point in the right direction.. I wouldnt be afraid to poke around the filesystem if need be.
Thank you!

[Q] Android gets into a hotboot looping state for unknown reason

Hi.
My Galaxy S3 is frequently getting into hotboot looping state for no apparent reason. The only way to get it out of this state is to wipe the phone or restore a backup of the "data" folder only.
After that, it might work for a week, but it might not work for a day (not work = start to hotboot loop).
It happens when after the phone screen is locked, it doesn't wake up anymore. It doesn't answers to any calls (like if it's off) or notifications. Just dies.
Forcing a reboot (by holding the power button) or removing the battery ables me to reboot it, but enter in hotboot looping state. I can make it go thru the whole booting state and I see the homescreen (And that's weird because I'm supposed to see the lockscreen first). Some widgets animation works but the device doesn't answer to touch (two softbuttons vibrates when touched, they do vibrate but don't render anything on Android) and then hotboots. Keeps doing this forever. Booting into safemode USED to work, but it doesn't work anymore, I don't know why.
After wiping the device or restoring the Data backup, device turns on as expected (restoring data takes it back to working state exactly like it was before the backup, even the same lockscreen pattern). I've tried to leave a terminal running logcat to catch the error, but it doesn't write in realtime, so when the bug breaks out, the logfile is empty.
I even thought it could be the S3 memory issue with firmware, but I'm using the "fixed" kernels. Also, it is recoverable, and not permanently dead.
I suspect of some rogue app, but I have too many apps to just go through installing one by one (and waiting even weeks to install the other one). Is there any way I can get a postmortem logfile or make logcat write in realtime?
Thanks

Try flashing another ROM for S3 and doing a full wipe.

I already did. It started to happen out of nowhere while I used the Android Revolution HD ROM, then after a few wipes and reinstalls with the same problem, I gave a shot to WanamLite ROM. Exactly same problem. Both are based on the original 4.1.2 Android.
I'm pretty sure it is being caused by some rogue app, because the only thing in common between those ROMs is that I "batch-install" all my apps back from Google Play.
So far, I'm suspecting about Vine (it's the last install that I remember since it started to have this issue) and I have already uninstalled it, but it might have been caused by some app update that broke hell to my phone.
If there were some kind of "black box" that I could retrieve after a crash, it could be the solution

If you wipe data, your apps disappear, so I think this is not the problem.
Do another full wipe and DON'T restore your data. Just download again from Google Play and see if the problem appear again.

I started doing this the first time, but it still crashes it. And as I was wasting too much time with this, the backup option came as a option to not have to click to download over 200 apps one by one. Also, it once happened during a long holiday, and I was in a friend's ranch with no decent internet connection for downloading. All my apps were gone and I was stuck with a default phone for five days.
The backup is exactly the point where I finish downloading all the apps and they're installed. There are no cracked programs or adapted (e.g. Nexus camera). Every single app is obtainable from Play Store, so it's pretty fresh
Funny (actually sad) thing is that it's a system-wide error that a wipe solves it. If I don't wipe data and reinstall the same ROM (which under normal condition is no big deal), it doesn't get past from boot screen.
The worst is it happens instantly. It's working now, but then it crashes. Bam, gone. Few hours ago I was texting my gf and I left the phone for a while, waiting for her answer. After some time I knew something was off, picked up the phone and it was pretty warm (first signal), with the LED blinking some Facebook notification. Tried to wake up but it is in coma. I force a restart and it hotboot loops like I described on first post
It -only- happens when screen is locked. I disabled the screen lock for now to see if it's a workaround, but I'm not holding my breath
It could be a hardware malfunction if it can carry through all the roms you flashed and even when you tried a fresh install without your apps it still happened.

That's pretty much discarded. Wiping data instantly solves it. It did indeed run for 5 days with no external app without a single problem.
But also it ran over one week with external apps without a problem. I've executed some memory integrity tests and they all reported a-OK.
I'm kinda ruling out the "rogue-app" issue. I thought that recovering "data" from NAND backup was the /sdcard/android/data. But it's deeper than that. Now I don't even have a lead.
Phone already crashed today, without Vine and lockscreen, so that's not the problem. I really need to get some logs out of him. Just need to know how. Only if it could write a realtime log, so I could pull through ADB.
My last resort will be a fresh-fresh android installation, default S3 i9300 ROM, with only essential apps. Already have it triggered for the next crash.
If it goes rogue even this way, I'm running triangleaway and returning it (will be a profit too, the silver border is stripping).
This time around, I'm trying running it without a external sdcard (several files were being corrupted in it, don't know if it's due to force restart by removing battery, or some real issue on the card)
It's a problem within the Facebook social app or Youtube.
I've managed to run the phone flawlessly for weeks without signing in on Facebook, suspecting it might be it.
Today I logged in on Youtube app accidentally, and had to login on Facebook app to retrieve some info. Three hours later, phone went mad again.
I don't know which app caused it, but I think there's some relation to Facebook due to a greater ~involvement~ (couldn't find a proper word.. forgot it) with Android.
I've changed ROMs, launchers, system versions.. but not Kernel. I'll try another kernel and report on Boeffla main thread to see if there's some known bug

S6 Edge restarting VERY OFTEN. No apparent reason

Hey,
I've had my S6 Edge for about a month or two now. Never experienced any random reboots until today. I restarted it earlier today, and now it keeps restarting several times an hour. It most often restarts when I unlock it, after the screen has been off for some minutes. It also restarts if I browse the internet or browse Play Store. It reboots to the Samsung logo, then directly to my home screen. I don't have to enter any pin, unlike when I manually reboot it. The phone is not rooted and I haven't installed any apps in days. It seems like me restarting my phone triggered this.
Any ideas or suggestions? It's VERY frustrating, the phone is nearly useless as it is now. I can't use it for more than a couple of minutes before it reboots, losing everything I was doing.
I have tried wiping cache. Still restarting.
Thanks

Try using it in safe mode. If the problem disappears you know it is a third party app
It doesn't restart in safe mode. I've uninstalled a bunch of apps but it doesn't stop restarting in normal mode anyway.
If the phone is fine in safe mode, it can't be anything but a 3rd party app causing problem?

Safe mode is very similar to normal mode.
The difference is all non-system apps have been removed.
It is a mode put into all Samsung phones to diagnose issues that may show up.
It is a very basic, simple way to diagnose problems.
Since your issue disappears in safe mode, try uninstalling every app you have installed, then download them again, one by one

Thanks. It turned out to be a bad app, that I installed a week ago or so. Of course, it was the one app I didn't want to have to uninstall. Oh well, at least it doesn't reboot every other minute now.
Thanks for the help, much appreciated.

It was Casper, an alternative client for SnapChat.
I have the same problem but samsung service centre fixed it by changing the main board and battery.
I had only one restart and had phone over month
And it restarted bcos I was installing all apps at once from play store ?

Question Random reboot - any Pixel 6 (non pro) users affected?

Wazzup.
Over at the Pixel 6 Pro fair, we have quite the number of people having problems with random reboots. We are trying to narrow it in - Android12? Pixel 6? Software? Hardware?
So - anyone here with the same set of problems? Or does the Pixel 6 not have that kind of issue?
For reference: https://forum.xda-developers.com/t/random-reboots.4353231/
I have gotten several random reboots as well. 256gb seafoam pixel 6. In particular, I was using "Frep" automation app (unrooted, used pc to start server) to do repetitive image searches in a game. Also the phone was sitting on a wireless charger while doing this. I noticed my phone felt pretty warm, wonder if it could be overheating?
Could be a naughty 3rd party app. Have you tried safe mode?
I posted this here:
P6 Bluetooth Problems
My p6 will see most some of my Bluetooth devices (laptop, tablet, TV, earbuds) . It pairs with the earbuds, but everything else it will try and pair, usually does not. If and when hen it does pair, that pairing is dropped dropped within 5 secs...
forum.xda-developers.com
My random reboots (or crashes that forced me to reboot) almost entirely stem from the wifi+bluetooth implementation. I found a sure-fire way to crash it during setup. Without word vomiting here, connecting the P6 with and to other devices has proved more difficult than any previous Pixel (for me).

Not yet. It's also hard to "force" it (the reboots, I am not able to replicate it manually). Yesterday it just randomly happened whilst the phone laid idle next to me, thrice at the morning, about one time through late afternoon, then one time evening. I just notice the screen lighting up, then the Google logo comes, meaning the phone restarted.
I'm also pretty sure that Bluetooth/Wifi settings differed when the reboots happened, ergo at some times bluetooth was on, then when it rebooted, bluetooth was off. At no time when the reboots happened had I a bluetooth device connected. WiFi was online though, all the time.
What all the reboots have in commong though (at least the ones where I am concerned), is that the phone is just laying next to me, or somewhere, being in idle - doing as far as I know, nothing. It never happened when I used the phone or put it under load, so my P6 never "crapped" out under me. That's why I am not that concerned about this as of now, but it's certainly a nuisance to unlock the phone every time with my darn pin.
(Concerning 3rd party app) - I'd say that's unlikely. I copied my files over from my Pixel 4 XL and have not yet added one singular other app to my P6 Pro, so it should have gone naughty before my transfer over.
Hi! I experienced a big crash on the pixel 6. When I was configuring telegram, the app crashed and then the screen got black. After a minute it rebooted to the Google logo with a loading bar underneath. It was blocked in that state, but I could reboot it with volume up + power button.
I was pretty scared as the usual button down + power button didn't do anything lol
12 (SD1A.210817.036) on my pixel 6, occurred randomly when opening camera app. Happend 7-10 times.

Odd. I never had a problem whilst using the phone, my phone only rebooted when laying idle (even though today I had no reboots at all, alas I didn't use the phone much, maybe 2h SoT without any heavy lifting).
Something in android 12 is bugging around, maybe we have to open support tickets.

I just talked for a while with a Google rep and he said that they are not aware of any reboot problems, no people over at Google Forums have reported such a thing. "We do not monitor Reddit or XDA" - so he said he opened a support ticket to the responsible team and they would look into it, he also asked that I / we report/feedback this under -> Settings -> Tips & Support -> Feedback.
We also talked about a lens flare problem, that at least the Pixel 6 Pro has. If you shot some photos where the sun is directly shining into the camera, you might want to re-check them. Most of mine have either some sort of big circular green dot in them, or a big beam of light like in a phone with a very bad HDR processing. It seems to be some sort of software glitch, he also reported that.
So hopefully those things can get fixed.
This was the follow-up email:
Thank you for contacting Google support.
This email is regarding the chat conversation we had earlier today, I'm sorry we weren't able to complete it. Hence I wanted to follow up via email to ensure all your queries have been answered.
Please re-launch the camera app and check if the issue is fixed.
Please be assured our developer team is working on this to fix it as soon as possible. We would really appreciate your kind understanding as we work on this to fix it for you.
If there is anything apart from this that needs clarification, please feel free to reply back to this email. I'll be more than happy to assist you.
Thanks!

I'm having similar restarts while phone is sitting on a table doing nothing. Tried a factory reset and was fine until overnight on charge and it happened again.
Also have had a few times where wifi has stopped working for some reason. Not sure if related.
Not had any reboots but quiet a few app crashes in especially FB will be scrolling away and bang just closes also Amazon app ,
Well that was interesting.. When it rebooted that time, it gave me an error screen saying it could not load and may be corrupt. I had two options, try again and factory reset. Try again got me back running, but I'm wondering do I got as defective device now.. or if it's software related.
So after a lot of messing around, I think I have narrowed down what may be causing my reboots. It only seems to happen when I am using "Frep" to play macros on a game while charging my phone.. the phone gets pretty hot, and reboots when I tap the screen or try to swipe home or recent apps. Maybe its overheating, or maybe its "Frep" playing naughty.. but Frep did work perfectly fine on my old $200 used Nord N10 5g. Will update if it reboots while not doing this.
no reboots or crashes so far, not doing any gaming - but using phone for email, surfing, whatsapp etc and also a work profile for MS outlook and teams.
I have/had similar issues with my Pixel 6 (128GB - europe unlocked).
I was transferring old data via cable from my old (Xiaomi Mi A1) to the Pixel 6. This resulted in sluggish performance, crashes every 15 minutes. The crashes would randomly occur and behave mostly like this:
Try to unlock phone with fingerprint sensor
Fingerprint sensor lights up, nothing happens, no haptic response
Swiping up to the PIN entry. Enter PIN and hit enter. Nothing happens. Now freeze.
Screen turns black and it takes phone to reboot on average ~7minutes
Factory Reset; Installed apps manually (standard messaging apps, no games etc), better performance, problem persists
Factory reset; boot into safemode. It now took way longer to provoke the issue. But it still happened.
After this I contacted the customer service and they will provide me with a replacement. But now after a night of idle, the phone was working for 3-4 hours without any issue at all with most of my apps installed. It just now went into a random reboot (could only notice because it asked for PIN because of the reboot). But not the 8 minute blank black screen type of reboot.
I am really unsure what is the issue at hand here. But have to say that experience is less than ideal.
Mine just happened last night, not charging or running anything 3rd party apps (all from App Store). I tried to use the camera after eating dinner and noticed that double clicking power button doesn't open the camera anymore. After unlocking the phone it appears that the phone has restarted.
Is anyone running Private DNS on their system like Adguard DNS or NextDNS? I did some searching and people reported some private DNS were causing Android to crash. It was suppose to be fixed in previous Android versions but it could be back again.
I haven't noticed any random reboots (and the lock screen will require a pin to be entered after reboot and says this on the screen, so you should know the phone rebooted). I've had the P6 since the official release date. In fact, I haven't restarted the phone in days.
I run a wide variety of apps. Some from the Play store and some sideloaded. I think that any reboot issues are probably app related. Remember that A12 is very new and the are surely still some compatibility issues that app developers haven't found/fixed yet.
