I am using the D802, bought it in Singapore under M1. I also use the flipcover with the quick window - bug does not happen when i unlock using it. On stock with TWRP and root.
The problem first started when I rooted my device, I noticed that locking it and quickly unlocking it again would sometimes cause a soft reboot. The problem went away after a while, but today it has rebooted on me at least 8 times.
My logcat is attached below(no confidential stuff there). I seem to be able to reproduce the problem pretty easily today, so I started logging from when I turned on my screen and ends when the phone shows the lock screen when I finish the boot(when the lock screen appears)
Unlocking is attempted the moment the screen turns on and all the widgets have loaded(1second?), and the soft reboot occur both with double tap and using the power on key.

I've already done a cache and dalvik cache wipe using TWRP 2.6.3.2 but it does nothing IMO
Any one has any ideas? I suspect a problem with me /system/bin/cnd file cos is keeps showing a "reading a NULL string not supported here" - it's the one error that keeps showing up. Any help would be really appreciated, thank you so much
I have seen this problem on many, many occasions with my T-Mobile G2 but in my case I did not dug that deep (logcat).
However I noticed the problem occurred while using either the Lockscreen Gmail Widget or the Launcher Gmail Widget.
Once I remove them, the problem is gone.
Cheers!
I see, thank you so much! Just removed it.

WOO. I thought I ****ed up my phone when flashing TWRP but you found it out Cheers. Going to submit bug report to gmail so they can take a look at this.
I don't wanna sound tacky, but saying thanks through the Thanks button is best!!!
Glad it helped!
I'm going to Copy and Paste a conversation between a girl who tried to help me and all the stuff I've done so far... any help would be great. Issues started upon download of Pokemon go....
Hi Aubry
This would also be faster to chat this way
Yeah, thanks for the help, btw
No problem
I like to help when I can
So, if you already have that message after the card is removed, it's possible you have malware
It's also possible that will the latest android update, something unexpected happened with your phone
Tech support is 99% troubleshooting
lol, yeah, I know
I'm just not as tech savvy yet, I wanna be..
If the memory card is out and you still get that message, I'm leaning toward the latest update acting up
That would make sense...
I had an update forced on me 2 nights ago, I think. Happened without my consent
So that's why I think it may be likely
Is the battery still out?
No, it won't turn on at all without a battery in
Even connected to power
That's a little odd. That might happen if you have a hardware problem but irrelevant to the current issue
Let's try this..... can you get it to turn off, perhaps by taking out battery? Wait a minute (or a few if you want to be safer) and then immediately upon Power up, go into safe mode by hitting home + volume up + power at the same time, holding for maybe 10 seconds
That may throw it out of the loop and into actually recovering itself
I got into safe mode previously by holding power + down
Should I do that or what you said?
There are several modes
lol, k
The combinations are android specific overrides
They're used for different purposes
We want to break the cycle, get out of a loop and begin to recover
You could alternatively do a factory reset, but you lose EVERYTHING that way, so I prefer to exhaust all possible options before recommending that
The main idea is that you have a soft brick, which is recoverable
I already did a factory reset earlier today
That didn't cause any change?
So anyway, now I'm Android System Recovery
It still was having the same issues yeah.. nt as bad at first, but once I put in the mem card, and it started installing my apps and stuff...
Same old BS
Hmmmm
If it's installing apps from the memory card that can be malware
I don't think it was, cause when I did the reset, I took the memory card out to protect my data.
My pictures and stuff
And it stayed out for a while.
Right but malware is code. So if the card itself contains the code, it will continue to install even if it stays out a while
If I'm understanding correctly
It gave me a few hiccups, this has stopped, that has stopped.. but then it worked ok. I was like Oh! It's good! Let's reinstall! ... and back to crap..
If it is malware, the second you put in the infected card, it installs
So if you put the card in the trouble starts, correct?
Sorry if I'm misunderstanding. It's a little harder to fully understand when the device isn't in hand ?
Sooooooo I should save my pictures off the card and reformat?
If you place the card into a computer (presumably with an adapter, if it's microsd), you run possible risk of infection. I would run a virus scan on the card itself, but outside the phone
If you can save the pictures, that's ideal. In the future, consider google backups to the cloud or amazon prime photos
Well, I tok out the card. Then I did a factory reset.... it gave me a FEW of the annoying "this has stopped" or that has stopped, but I don't remember what, now.... It started installing stuff, but some programs it refused to. Clean Master, Pokemon Go.. it gave me error code -504. Then I forced some and it seemed like they were working ok and installing, so I figured maybe I was just DLing too much all at once. So I went back and put in my mem card in, and it froze. rebooted, and **** went to pot again.
I had Google Drive, but it kept filling up my phone's hard drive and prevented me from doing stuff, DLing more.. I had to clear all the data.
Hmmm
I'm lookin up error code
kk
-504 is specific to memory and data collision
Basically, one aplication said "I want to be king of the playground" the firmware said the same thing and they shoved themselves off the playground and both broke their arms
My analogies are bad at 2am
Anyways, when this happens, it's also related to the Google account data having issues with software
Ultimately, the Google services framework needs to be cleared
But how to do that without being able to boot is the problem
I can boot.. kinda.
But it freezes up quick
Right, but the associations and cache will freeze ir
Exactly
Who is your carrier?
Straight Talk
Ah.
That may be trickier
A regular kiosk usually has the software that overrides this to fix the firmware
Like,most of the time, it gets to the "A service of Straight Talk Wireless" and stopps there
Yeah that can't boot fully
You can't get into the settings, right?
(and I am really sorry for my typos, my husband is a slob and his keyboard on this laptop is filled with gunk.)
I can, sometimes~! I can try
If you can get into settings, the cache could be cleared
So just reboot normally?
If you can
But you likely need to be in a recovery mode
Hmm. Would it be best to go into safe mode for this or normal?
The developer resource says:
Go to ”Settings”-> “Applications”-> “Manage Applications” and select “All”
Go to “Google Services Framework”and select “Clear Data & Clear Cache”to remove all the data regarding Google Service Framework.
Go to “Google Play Store”and Select “Clear Data & Clear Cache”to remove all the data regarding Google Play Store.
..one question... will that kill my data in Pokemon Go.
If you could get into recovery mode, which is holding down power + home + DOWN volume, that may work best
No
Go data is all server side
Whew, ok
In theory, it should never be lost
Ok, hang on, gonna try this
(Thank you SO much for all the help)
If the above steps don't work, a second "easy" method is de authenticate you, meaning remove your accounts
The recovery mode gives me the option to wipe the cache a head of time, should I do that too?
Yes
Absolutely
Deleting cache is our goal
Ok, now it's updating andriod.. but stopped cause I'm at 12 percent battery
Oh that's no good
If the battery is too low it might quit
Did it give you the low battery message?
No stayed on
I mean, told me the battery is low but
Ok, in settings
Hang on
Oh great I thought you mean it forced itself off
It HAS done that before, but not right now currently
Go to ”Settings”-> “Applications”-> “Manage Applications” and select “All”
Go to “Google Services Framework”and select “Clear Data & Clear Cache”to remove all the data regarding Google Service Framework.
Go to “Google Play Store”and Select “Clear Data & Clear Cache”to remove all the data regarding Google Play Store.
Ok, so I'm in settngs, applications, but I have Application Manager.
Ok
Might vary depending on version
When I go there it gives me a list
Ok what do you see?
Do you know what phone and android version you are running, by the way?
Android System Webview, ANT Radio Service, AANT+ Plugins Service, AVG Antivirus, BatteryDoctor, my apps.
I might have it memorized in the deep recesses of my brain
That's my device right now
You need google services framework
It may or may not be totally alphabetical
clearing the cache did seem to help though..Ok, so I need Google Play services? I found that
Ok great!
Now.....
Hit clear data and then after clear cache
Those buttons
Ok, so when I tap it it won't show it to me. It goes back to the Applications main menu
When you tap services?
Yeah
That's interesting
Can you try again?
it acts like it wants to, and then gets kicked back out
Sure hold on
Yeah same thing.
Ok try going to Google play store instead in that list
Something is preveting it.
It might be malware or issue with the firmware
Same thing with Google Play... or any app
Google play store is the name of the app
Yeah, I know
I tried it with a few of them randomly too
You should click on that and then attempt to clear that data
Its not letting me access any of them
Ok new plan
Go to “Settings”-> “Accounts”-> “Google” -> Select “Your Account”
Go to “Menu”and Select “Remove Account”, and then “Add Your Account”.
Now “Restart”your mobile device and try to perform update or download.
Ok, so delete my account or services?
If it doesn't say remove, you can delete
that won't delete my gmail and everything right? ?
I sure it won't but just making sure
Well your Gmail will still be on the server assuming you didn't pull it down
I probably sound like the typical idiot here.. yeesh
And delete it on the server
Nah
Then it should be ok
I won't do that, had the account for like 20 years lol
Ah ok
It wants to open it with Chrome or Internet?
Chrome is fine
I hate "internet"
....and now "Unfortunately, Chrome has stopped."
That is unfortunate
Please turn on airplane mode
Airplane on
Ok we are going to wait a minute now
kk
For fun, let's go back into that app list and try clearing that cache again
While airplane is off
Also, if it's late, I can also send you messages later
I'm a 3rd shifter, I'm fine if you are
Yeah I couldn't really sleep
And just tried while Airplane was on, no dice, same BS
Try restarting while in airplane mode
You can hold power
And then restart
Ok
Ok, booted fine
Yay
Now once it's rebooted you can take out of airplane mode and see if the data can now be cleared
Now it won't go into the application list at all
That's sad
Ok time to try something else
On the settings screen, can you find "backup and restore"?
Backup and reset...
Yep that
Ok, in it, now what?
We can try a factory reset from here.
But before you do that
Already did this earlier but sure. XD
Hmm?
Uncheck the boxes that save the app data
So uncheck "Back Up My Data" and "Automatic Restore"?
Yes
You will lose your phone data
That's fine. I know what I need
But at this point, without installing firmware to fix it, it's pretty much the best bet
Is it normal when rebooting the phone it keeps the old apps up and running? I don't remember it doing this previously but it's been doing that lately
Alright.. So factory reset time yes?
I think so
The factory reset should wipe everything
But again, if firmware was badly enough affected you would need more than this
And it might possibly be better to get a new phone, depending on factors considered
But at least the most common solutions were tried
Ok
Welp, got to the tracfone screen... and it's stuck.
What do we mean by stuck?
Frozen?
Whatever is in there, it's in there good
Yeah. It does three boot screens. 1, the Galaxy Grand Prime screen. Then the Pretty Samsung one with the musical tone. Then the Tracfone screen, then it boots. Since these problems started, it will often freeze on the Tracfone one.. cause after a few seconds the screen will dim. And then it boots.. but like, before I took my husband to work.. it was still froze there. I had to pull the battery, cause it wouldn't move. Though, just now it did finally
If it is incapable of factory reset, it's the kernel. That really would have to be handled by the dealer who sold the phone (if under warranty and they feel like replacing it) or doing things that void the warranty anyway
Well, looks like it finally got to boot...
huh.
If it moves, I would say to give it a little more time
That's good news
We are hoping it's not the kernel
....and I selected English, and "Unfortunately, Settings has stopped"...
That might not be a huge problem if it progresses
Settings might be fussy but it can be overlooked for now
Does it look like a factory reset took place?
Like it's new without apps, data, etc?
Same start up and "Welcome!" screen from last time.. but now that I select English it won't go past it. Keeps saying settings stopped.
Oh. That's different than settings stopping on the home screen
Yeah, it's acting like I just bought the phone
If settings are failing to load during language selection and you can't get to the home screen, you can try takin out battery for 10 minutes and then try rebooting and trying again
If it still fails to work after 24 hours (sometimes if you leave it alone long enough it'll work) I'd go to where you bought it with proof of purchase and hope they'll help get a new one
Ok, battery removed. Is it possible it's an overheat issue? Cause when we were playing Pokemo Go Friday night, my phone froze.. and when I booted it the screen went black, and lines went through it, like it lost connection to the MB or something
I've had issue like that with like, DS lites when the ribbon cable gets crunched.. but...
It's possible the hardware overheated, but because it boots, it's not necessarily a gonner
I've taken very good care of this phone, no hard drops or water...
It seems it's definitely a firmware and software issue
If there is a malfunction and it overheats from processing too much at once, that is possible
If the memory can't handle it and it's overloaded
Ok. Cause when that happened it was hot as ****.. and that's when most of these issues really started
I was having the "stopped" messages but only about my SMSs
If it was hot out that is definitely a possibility then
Leave it alone for as long as you can. Maybe all night and up to 24 hours
And those started literally after Pokemon Go.. I would have to stop Pokemon Go cause it would freeze a lot, I don't know if that did anything
But all this happened after I started playing it.
The game may not be good for the phone
Honestly, a lot of the pay as you go phones are not really suitable for mucj processing
I've dealt with a lot of them
They sometimes have trouble with games
I would absolutely submit a bug ticket with Niantic
I soft bricked my phone (and recovered it) because of pokemon having an issue during a specific sequence in game play. It definitely has bugs
I warned friends about it and that other phones may not be recoverable. It really depends on many factors
I've noticed it allowed me to install it on both my tabley (really crappy NextBook from WalMart) and my husband's phone (LG Fuel) and it won't run on either.. I figured, 200 dollar phone, it should be able to handle it....
It ran fine, but now.. and it sucks cause this is how I run my etsy, is this expensive brick
For the record, I have now tried yet a third factory reset. Now my phone won't even get past set-up. Any help would be amazing...
On an unofficial capacity, I think your phone may have been google account locked. This commonly happens when you forget to remove your google account before factory resetting the phone. You will know if your phone is google account locked by holding Volume up button + Power Button + Home Key, then when you get blue screen press volume up button, If the FAP lock: ON, then your account is google locked (Google locked phones tend to not allow you to go past the setup screen as you cannot click the "next" button). You can send it in to your phone dealer for them to send back to Samsung for repairs, however you seem to live in the U.S so I don't know their policies. I live in Canada and work as a part-time Samsung repair technician and our policy is to unlock the google lock and factory reset then return to phone company. However, that is not covered under warranty so we do it as a sort of "customer service" capacity.

It is FRP, not FAP, it means Factory Reset Protection.
Well, if that is the case, on the setup you will get a window telling you to choose the WI-FI you want to connect to. Do it, then try to log in with your gmail account (This "gmail" account must be the same one you used last time otherwise it will not work.
Been a while since I had any issues with a phone I couldn't fix, but this is usually the best place to come when you run into something weird. Whilst I very much suspect that my phone has reached the end, there maybe something I can do if someone here has seen this before and managed to fix it.
A couple of days ago my phone started acting weird. Google assistant would start up for no apparent reason. Sometimes if I was in an app I'd just get a pop-up message but at other times I'd be taken to my home screen. The frequency came and went, but at it's worst it would happen every few seconds and would last for a good 5-10 minutes.
Thought it was just something weird in the OS so I booted back to the factory reset menu, wiped the cache and the system partition and started again. That didn't work. The start-iup process began with voice assistant turned on and every button click requiring activation and double clicking. I've since tried 5 factory resets.
I've disabled Google Assistant now and removed any updates. I've wiped out it's cache and tried all of the settings to make it stop so I no longer get Google Assisitant launching, but I do get something happening which asks me to "complete action using" and shows me the Samsung internet app, S Voice and Quick dial.
This is making me wonder if I'm looking at a hardware problem. I've switched everything off and given everything a good clean just in case one of the buttons has something stuck in it but that hasn't changed the situation.
If anyone here has any ideas or suggestions then they would be very gratefully received.
Thank you
Clean dalvik cache and update stock software through odin or custom rom may solve your problem
Thanks, will give it a go, forgot about the dalvik cache in the last reset so a good heads up. Will have to look into Odin, not had to use that in years.
FIrst the issue: Every day once I let my phone laying around for a couple hours, it will behave oddly and the "Always On Display" app will keep crashing and the phone will flash the screen trying to start again the app and it keeps in this loop forever until I restart it. If I try to open the phone main screen it will sometimes say "Always On Display" stopped working or "System UI" stopped working or a combination of both.
After rebooting, it works fine again for maybe another 20 to 24 hours.
Details:
This started happening one day after I changed the system language. My phone has always been in US English but I had a problem with a local app in Portuguese so I added the language and made it primary. After that I simply changed English again as primary and left Portuguese as secondary.
I don't know if this is related, but is very suspicious since when you change the language, lots of things in the UI behave differently for a while. After seeing the issue, I did remove Portuguese from the language list but I'm guessing the damage to some setting might already be done because the issue persists.

Hey I did face the same problem... I changed the theme and it stopped happening... Usual with high contrast themes they crash
Just give it a clean wipe and restore, see how that goes

Juste delete systemUI app and always on display app data or factory rest. Make sur u are on last update
Hi!
I'm having the same problem. I just came around at the 15th January. The first days it happend once a day. Now every 3-4 days.
I tried wiping the cache, but it didn't help. We are also discussing this topic at a german android forum. Someone reported there, that even a factory reset didn't help. The error occurs some days later again.
I suspect it's due to an app update, which is causing the problem.
Yesterday I tried to delete the systemUI ans AoD App data, like @KarimAssiakh suggested. Now I have to wait, if it will happen again.
Has anyone else found a working solution?
It's me again.
Deleting the System-UI and AlwayOnDisplay data didn't help. I'm still getting the error every 3-4 days.
I'm trying to avoid a factory reset. I also read in an other forum, that a factory reset won't help. The issue came back after some days. Maybe it's caused by an app update.
Has anyone found a solution to solve this problem?

Wow, nice to hear. Thanks!
I have some questions to understand what you did exactly. Maybe I will try it in the next days.
After the down- and upgrade the error didn't occur any more? How many days ago did you do the reset and how long was your device running after that? Because the error only occurs after 3-4 days at my phone. Maybe your just in this range?
Did you install all your apps again and made the same settings like before or do you use a different setup now? Did you use a full backup with the LG tools for your apps, settings etc?
Is your AlwaysOnDisplay activated? It seems that the AlwaysOnDisplay is causing the problem.
It would be great to hear from you again.
Thanks!!!

Bro not one's I've got the error... After I did the process... As far as I remember when the error used to occur I had to restart the device altogether.. Yeah download you're region kdz and lguppercut
Seems I am late to the party because this happened to me also. Have you guys tried the solution below? Posted by someone who goes by the handle XGXGXGX over at Android Central

Same thing happened to me, the file size of the photo is too big. Did a hard reset and cleared phone cache and it didn't work.
The fix: Go to:
Settings
> Applications
>Press Menu Button (3 dots in the top right corner)
>Choose "Show System Apps"
>Always On Display
>Force Stop
> Clear Data
>Clear Cache
This worked for me. Got info from another forum with instruction to only clear Cache, but that didn't work, so I did all of the above instead and it worked. I have the T-Mobile version.
Obviously the G6 has Always-on display Provider and Always-on display apps you will have to drill into , stop, and clear cache.
I've tried it and I will report my findings...
I purchased a Mi 9t a few days ago, and I'm experiencing a recurring issue that I can't seem to solve.
From time to time, the UI will simply crash. I can still see my apps but I can't open them, and the notification bar on top of the display just disappears. I can't access anything and my only solution is to reboot. Sometimes I'll have to reboot multiple times a day, which gets old quite quickly.
Most of the time it seems the issue occurs when I'm trying to go to the home screen, whether with gestures or with the home button.
- At first I thought it was a conflict between the gestures in Nova launcher and the gestures of the phone. Turning them off in Nova didn't fix it, so I tried to disable the phone ones and started using the navigation bar, but it didn't fix the issue either.
- I did clean Nova launcher's cache along with the system launcher's one, didn't fix anything.
- I tried to do a full factory reset, it didn't fix anything either.
- I tried to disable the search bar, didn't fix it.
- I tried using another launcher, didn't work.
- Using the system launcher didn't work.
I'll add that my phone and apps are all up to date.
I didn't find anything helpful on the internet, and now I'm out of ideas. Is it software, or could it be hardware ? I can still send the phone back and get a replacement, should I ?
Thanks for your input !

Hi there,
When you did a full factory reset did you start from scratch or did you import your backup?
If you did it with your backup once you were setting up your phone again, it may be some app that you have recently installed.
If you did factory reset (without restoring your backup) and still experience the same issue it could be Software/hardware issue (software being more likely) and yes you should send your phone for repair or get a replacement phone.
But before you do I would advise you to wait until another software update / Security patch is out and see if that resolves the issue for you if it does it was software issue if it does not it is a hardware issue.
Hope this helps
Thank you for taking the time to write an answer, I appreciate it !
Because of a delivery error I received a second device, so I decided to switch and send back the first one. I also suspected that it was more likely to be software rather than hardware, but thought I'd do it just in case. So far the issue happened once on the new device.
You raise a good point I hadn't thought about. I transferred the data from my old phone to the new one, at first. When I did a factory reset I entirely wiped the data on the phone, however I had backed up my data with Google and the Mi cloud, which I restored.
I think I'll try doing an entirely clean install if the issue persists. Thanks you !
