Never had this before (Android 11). after 3 week updated to Android 12. this issue happen.
is it probably Firmware issue? currently im on G988BXXSCEUL9 XME (Malaysia)

Try using different fixed frequency display rates and brightness levels.

Tried turn off adaptive brightness
Change from 60hz to 120hz and back to 60hz
Turn off/on night light
Eyeshield off
Screen mode to natural
Resolution to 1080 and 720
No luck.

Guess try reflashing it. If you can downgrade do so. Maybe a mobo failure, if a downgrade solves the issue... leave it there.
If under warranty, send it in.

Not sure as I haven't had to do it. I rarely mess with the firmware if it's running good even to do updates. This N10+ is still running on Pie, the current load will be 2yo in June.

Alright thanks for the reply. I will just wait for next update hopefully it will fix. Otherwise i'll just buy new phone

Not written in stone. Maybe a loose connector or it got corrupted doing the upgrade. A Samsung Experience center at a Best Buy might be able to find the issue and if firmware, reflash it.

I downgraded back to Android 11 Nov 2021 build using Odin (my esim data doesnt get erase).
no more flickering screen after 2 hour of usage, i will keep monitor the display and update here again.
Hopefully its the Android 12 Firmware issue not my hardware.

Could be either or a combination of both. Best shot is to not update/upgrade it again. It can run for many years like that.
Android isn't PC and anything from Pie up is reasonably secure as is.
With 11 you have more than enough security in place unless you do something stupid... which is how malware usually gets loaded.

Hi
I'm having the same issue in my s20ultra exynos G988b/DS and it's nearly 2 years old and in clean condition. got this problem last week and it wasn't under the warranty anymore service center said it was hardware and need to changethe display which cost ~$290 which i refused since the device is not even scratched and pretty sure must be a software thing.
Came across your post today, can you verify that problem has gone after the downgrade?
Thanks in advance.

Please help! Galaxy Tab S glitch.

So, I got a Tab S a couple of months ago and then about a month ago I started having some trouble with it. Lines flashing down the screen and the screen turning off. I'd have to lock and unlock to get the screen back on. Sent it to Samsung for repair and they sent it back about two weeks ago saying they couldn't find a problem. Well, the problem is definitely still there so today I took a video. Samsung said I would have to send it back in for more tests and that they would not watch the video. I'm afraid they're not going to find anything again so I was wondering if anyone had a similar problem and could help.
Samsung Galaxy Tab S 8.4 glitch: https:// youtu.be/ 7kOFewYbNzw
That's the video, remove the spaces
Does it still happen when you use power saver mode?
When the display goes blank, you press the power button twice, once to enter sleep mode, and again to wake it up, so it looks like a loose display connection or a faulty display, does the screen ever come back on without pressing the power button.
Does the brightness level effect how often the display goes blank?
John.
Thanks for getting back to me. It does still happen on power saving as it turned that on not long after I took the video. Screen brightness I'm not sure though because I packaged it back up to return or send for repair, whichever I decide is best to do.
This happend to me 2 times in the 6 months I have the tab s, seems more like a software thing for me.
All you can do is a factory reset, then install no apps (in case they cause the fault) and see if the problem is still there, if it is, all you can do if you are still in warranty is get an replacement or repair.
John.
I've got the tablet back out of the box while I wait for my repair packaging. I did a factory reset when I got in from work and restored a backup and straight away I had to the same problem. I've now done another reset but with out restore, I haven't even logged in to my Google account. So I'm thinking it's either an app I have installed, not that there were that many or some of the factory installed apps I disabled/removed. I don't think the restore from backup reinstalled apks such as remote play and show box so they can't have been the problem. Could deleting any of the factory apps cause any problems?
You can only delete factory apps when you are rooted, any you have delete without root will make no difference to your tablet stability, try and use the stock apps and see if the error shows.
John.
I've disabled a couple of them like New York times and the office suite one. It's working faultlessly at the minute. The problem is when it came back from Samsung it was working fine for about a week and then the problem returned so I can't be sure if I've solved anything or its just a ticking time bomb.
I don't know how Samsung tests the tablets, they will just send it back if they cannot find a fault, download a couple of benchmark apps, to stress your tablet and see if the fault shows up, see if increasing the brightness while benchmarking doe anything.

Just ran Geekbench 3 adjusting brightness from lowest to full and nothing, worked fine. I'm at a loss, I know that if I send it back to Samsung they're not going to find anything and spoke to Very today, they won't refund me without Samsung authorising it.
Is that Very UK, if so they send phones and tablets for repair, if they cannot repair your phone/tablet in 30 days they give you a refund unless as you said the manufacture says to refund.
Hopefully your problem will not show again, but it could have been an downloaded app, or an update to an stock app that causes the problem only time will tell.
I suppose you are on lollipop, I decided to stay on Kitkat as it`s super stable for me.

Yeh it is, but I bought it a couple of months ago. And they've have to find the fault first.
Hello i have similiar kind of problem i mean it shows stripes and boom reboot or sometimes screen goes black.I wonder if you found any solution?
Have you done a factory data reset from the settings menu, you will loose all internal user information so backup first.
If you have done an reset and still have the problem and you are on the stock rom and have not flashed an rom and have not rooted then you have an hardware fault.

If you are out of warranty check the battery as it sound like an bad connection or a bad battery, there are guides on youtube on how to get the cover off the tablet, you can buy a kit from the link below for $65 or cheaper on ebay for the battery and pry tool.

Galaxy S20 Ultra Boot Looping / Shutting Down

Hi, I have a Galaxy S20 Ultra 512GB from T-Mobile. I have an issue that manifested itself a couple of hours ago, and have never encountered anything like it.
My S20 seems to be shutting itself off every time it boots fully and I have no idea how to fix it. I have tried safe mode, clearing cache, etc. Nothing has fixed it so far.
Is there anyone that could guide me in the right direction to potentially fix this, or do I have an expensive paperweight?
Edit: I have tried factory resetting as well now, and that did nothing to fix the issue. It gets part of the way through setup, then reboots again. Maybe I could be directed to try flashing the latest update file?
Edit #2: I was able to figure out how to fix the issue entirely and no longer require help, unless the issue crops up again.
Edit #3: I have no idea what's causing the issue but it's back. Phone shuts off after some time of use, I have no idea what to do at this point...
In case the issue persists after a factory reset and not using a backup to restore the phone I would suppose that the unit is defective and return it, if possible. If return is not possible, you could try and have Samsung repair it as it must be covered under some warranty, as it is brand new.

Yeah... I tried to get into contact with T-Force to have T-Mobile send me a replacement as I am still financing the phone, but it looks like they don't even have it in stock and mistakenly are trying to send me a downgrade S20+ variant instead... Looks like I have a very expensive paperweight on my hands.
As for Samsung, all they were able to offer me at this point was to take it to a service center but with the pandemic limiting everyone to be able to work or go outside I don't think I can even do that at this point.

It doesn't say what you tried to do to fix this - so if you haven't already -- I suggest downloading the most recent firmware (via Frija) and then flash in Odin. Don't use the HOME CSC - use the other one, this will force you to wipe data when it first boots up - when finished, it will boot up and you can set it up like a new phone.
If you don't already have it, you can download FRIJA here: https://forum.xda-developers.com/s10-plus/how-to/tool-frija-samsung-firmware-downloader-t3910594
Be sure to use the most recent patched Odin - https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
If this doesn't work, then it is most likely a hardware issue - but try this first to be sure.
Hope this helps.

Hi, I tried exactly this process and the issue came back after a few minutes of using the phone along with a bit of graphical corruption when trying to use the phone. I'm guessing it's definitely a hardware issue. That's too bad though, I tried to get a replacement through T-Mobile and they have none in stock, I guess I'll see if I can get Samsung to replace it.
Good luck!

Thank you! It's been a week now and I made a ticket with Samsung to have the phone repaired the same day I posted about it. I finally received my repaired phone, it turns out there was indeed a bad SoC on the motherboard and they went ahead and replaced the board, so I got to keep the phone I bought. It's too bad I couldn't recover my data, although I don't feel too bad about it anymore.
Mods feel free to close the thread, as this has been solved.

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?
I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U
It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.
Updates, destroyers of worlds...

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.
Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.
Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...
Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....
Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.
I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..
Not very helpful, but a work around could be to use Screen Filter

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?
Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.

Question Regular, repeatable shutdowns

Someone please give me hope.
I've got this phone yesterday and it keeps turning itself off when locked. If my phone doesn't receive a "wake up signal" like a notificationn or isn't in charge it will turn off in around 5 minutes (measured with a clock). This is not a sudden shutdown or crash ,you can see the logo on the screen.
Neither safe boot nor factory reset solved the problem.
Returning it and buying it again at the same price is impossible now so i'm hoping for a fix before the return window ends.
Can Xiaomi fix my (and probably others) phone in less than a month or is better to throw the towel now and go for a full refund?
Oh.. Had a few unexpected shutdowns Yesterday.. and one today.. but it's Not reproduceable.
Have you tried to enable AOD? Maybe this is a workaround....
Yeah, even with AOD permanently on after around 5min the phone shuts off. I've also tried running the clock app in chrono mode in the background with no results.
Rightnow i'm trying to reinstall miui 12.0.2 cause i don't understand if this is an hardware problem or a software one.
Also we don't know how widespread this problem is, a lot of people are happy with their F£ but it's impossible not to notice a problem this serious
Just ordered the phone, will come in a week, what version of MIUI does it come with, Global stable or Global beta?
Bro try unlocking bootloader and installing xiaomi.eu

I have the same problem. Got it yesterday, went to sleep and in the morning the phone was rebooted/crashed.
Had to put in Sim pin and Device pin again just like after a reboot.
I hope this gets fixed soon.
Same problem here, I have the f3 for ten days with MIUI Global 12.0.4 (Italian Country), several reboots (four) almost always at night under charge, but once even during the day in front of my eyes, another time I have found the smartphone completely turned off, at this point I don't know whether to ask for a refund because I don't know if it's a SW or HW problem
There are several users who are reporting this problem
Hmmm i think the update from yesterday solved the problem for me.
I didn´t have a reboot this night.
Edit: Had another reboot this night, so update didn´t help.
UPDATE: i've updated the phone to 12.0.4 and the problem still remains. i will ship it back to Amazon in a few days. Also the problem got even worse ( before update): it's the second time i've found the phone with 0 charge after one of those shutdowns. The "when isn't in charge" part of the OP is also wrong, in the last days the phone switched of even while charging
Had a reboot this night on 12.0.4
Before putting it definetly inside the box after factory reset i've tried to start the phone again and then lock the screen at the welcome page. After 10 mins i've found it turned off
Same problem for me. I wonder, does it also happen on xiaomi.eu rom? Hope its not a hardware fault.

Pretty sure it´s just a software Problem. During my search for a solution i found out, the Poco x3 had the same problem.

That can't be, if it was a software problem all of us on MIUI will have the same experience. I think mine is a hardware problem cause is worse than anyone here. Also a lot of people do not have any problems so maybe is a QC issue on some component like the power management chip
I dont have any shutdowns or reboots at night, but i use an old charger with 800mA.
My Shutdowns come If i disable AOD.

Question Samsung Galaxy A 32 4 G has a blank/black screen after Android 13 update. Any ideas?

Hi everyone, the phone was working fine, it was left to do an update for 3:00 in the morning. Couple hours later realized phone was blank/ black screen. Followed steps to do power and volume down and all it did was vibrate. It vibrates when plugged in. Two technicians looked at it and said it was a screen problem but a new screen was tried and it only showed a charging sign and after that it went blank again. I am wondering if it was android update that breaked the phone or is it something else. What specific hardware failure or is this software failure?
Any help would be greatly appreciated. Thank you.
My cousin had a similar issue with a black screen when they woke up - however their phone automatically reset itself and lost all data while updated to Android 13 overnight.

Hi, Thanks for reaching out. Definitely seems to be a Samsung problem. This problem however cost me a phone. That's life. Thanks again.

tried a firmware reflash?
anyways yes. samsung is a **** and has given me terrible experience with my a32. they dont pay attention to midrangers at all pushing out broken ota updates. My fingerprint sensor is now bricked permanently (no like actually. downgrading firmware doesnt help. its just gone. its fine physically. according to logs but something else broke ig). Then that stupid mobile data bug. where if i was using mobile data jt would disconnect from the cell towers and reconnect. as if there was no service. i saw many people have this issue. I was forced to use a gsi. One ui 5.0 is still pretty terrible for this thing. its not optimized at all. I am waiting for one ui 5.1. the final big update for this phone. Samsung seems to be pushing it out for all the phones. even cheaper than this phone. but looks like they forgot abt it.
