Update: Found the culprit! When the phone is on a 2G network, it happens always when there is any (voice or data) communication and glitches are stronger when the signal is weaker. It's probably caused by an interference and bad shielding of components. Similarly how 2G network makes buzzing sound in radio speakers, on A52s it makes a mess on the screen.
At least one user (bellow) solved it by RMA - sending the phone to service and getting back new/fixed one.
Update 2: Problem fixed. I sent the phone to service center with description how to replicate the issue (phone must be on 2G network, ideally low signal, data or voice transfer is happening). Got it back after 2 weeks. Report says they replaced the display and also battery for "construction" reason (as they described it) and issue seems to be solved!
To conclude: It is indeed hardware issue and is fixed by replacing the display. If this happens to you too, don't wait for software update or anything else, send it to a service for a fix covered by the warranty!
Since few weeks ago, maybe since last update a month ago (security update from 1st October 2021), I'm randomly getting graphical glitches on my A52s.
It usually happens when I wake my phone after few hours of screen off but today I also saw few flashes even when playing a (graphically not demanding) game.
There is colour noise flashing over parts of the screen. It is usually just few random quick couple of 1/100 sec flashes, sometimes it stays a second and it disappears and everything is okay after that.
I also saw noise not covering the screen but flashing instead of wallpaper... Like there's a corruption in graphical memory, driver or whatever.
It doesn't make a difference whether the phone is freshly rebooted or running a week or two.
Does anybody else have this issue?
Is my phone (the memory, screen cable or something else) dying or is ist just a bug in current system update? I don't experience any other instabilities or problems.
(I'd send my phone to RMA but since I didn't find any consistent way to replicate this, it would make just as much of a difference as locking my phone in a drawer for a month.)
I'm appending mock-up screen shots how some of the flashing glitches look.
Clear system cache, hard reboot.
Huh, I didn't really ask for help, but yeah, that's a good idea with clearing the cache.
I rebooted to recovery and wiped the cache partition.
(I also accidentally hard rebooted when trying different button combos to enter the recovery LOL, so I did both things. In the end I had to enter the recovery using "adb reboot recovery" command because none of the button combos I found worked for me.)
I'll report back in few days whether it solved the issue or not.
Your screen is dying. This is hardware issue

A possibility as is a mobo failure but no harm in trying a few simple fixes first.
Samsung has been having a lot of issues with their displays this year...
It doesn't really feel like screen itself is dying when glitches can appear under the home screen icons in wallpaper or in the application area with status and nav bars being untouched. But I guess it can be; I have no idea how the image on screen is being redrawn.
But it happens especially after phone display is off for longer period of time. The phone then is quite sluggish, presumably because the system paused or killed some apps and is waking them up. And glitches mainly appear then.
That would suggest to me either a system memory being corrupted or something weird happening in the cache, depending on where these apps go when they're paused/killed.

Factory reset. Before loading apps confirm if ok.
Then be careful what 3rd party apps you load.
If the reset doesn't work, reflash it to a known good version.
If all that fails it's likely hardware.
The most likely cause is a 3rd party app given right to overlap other apps and this 3rd party app has crashed. Uninstall apps in opposite order of installing until problem is solved. Or factory reset.
I have the same problem, sent phone for repair.
In my case, the issue is occurring when phone is on 2g network. You could try going to network and set it to 2g only, check if it's happening, and then set it to 3g and see.
Cheers!

I have the same problem, and I can't replace the phone, the question is here, will this problem increase and affect the screen more?
Same problem here...but mostly when I am on 2G network (anyone please try and post results)...Thinking of sending phone to service...will see how it goes
Huh, I didn't get notifications for my thread, so I didn't know about all the replies!
I tested different things in last few weeks and I came to the same conclusion - that it only and always happens when my phone is on 2G network. If 2G signal is strong, it's occasional small glitchy line here and there. When the signal is really bad, it just messes up the whole screen - I had my phone ringing with screen being all just noise and mess. So I guess it's probably because of interference similarly how the 2G network connection makes buzzing sound in a radio speakers. Except here it makes a mess on the screen.
Now that I know how to reliably replicate the problem, I'll back the phone up and RMA it after christmas.
i have the same problem from the first day, it happens only in 2g signal ...and only if 2g signal is weak... i sent the phone to Samsung , they inform me that they know the problem and it will be fix ..on another update ...it s software problem they told....from this day i have take 3 updates and nothing happened....the phone still have the problem
Same here, took my a52s to a Samsung authorized repair center, after 3 repairs (the third one being the display change) it seems that the problem is solved. To me, it has nothing to do with software.
So, it's a hardware issue, I face the same problem for almost 2 months, and I don't know what to do

I've seen a couple of people post on this issue but not many is facing it so i'm wondering if it's cause by a certain software? Or is this just another bug in the 2.1 and hopefully it gets fixed in 2.2
I've got the sound manager app installed to activate the vibration again once it stops. Usually it's for my SMS but over the last 2 days, even when i draw the unlock pattern, it does not vibrate anymore until i re-activate it using sound manager.
I've read that it could be the battery being weak but my batt was at some 65% so i'm guessing that is not the reason.
Anyone knows what maybe causing this vibration to stop issue? Maybe it's an application causing it....my only guess is "Handcent".
I've had this issue for the last month.
I've tried a few different things and usually it comes back, one way or another.
A few days ago I discovered something that leads me to start thinking I have a hardware fault. My vibration disappears almost daily now but the last 3/4 times it's gone I've done nothing except give the phone a light tap (light as in two fingers on the back of the unit) and the vibrate function has immediately returned.
I'm just guessing but it kinda looks to my untrained eye that it's a hardware issue on my handset - it may just be mine though.
Ha....if that is the case then you probably have a faulty hardware. No tapping is going to make mine vibrate until i launch Sound Manager to reset the vibration setting
I'm gonna contact HTC and get it sent back in the next few days for sure. I think I'd prefer it to be a hardware problem (fixable) than a non-descript software issue that may or may not be fixed at some point in the future.
Well I hope there's a permanent fix soon for you
mine always has some problem with the vibrate too...
Anyone any news? The vibration of my Desire is not stable, you clearly hear changes in the speed/power. I contacted HTC and wait for their answer.
For your information, it does always work and I am using Android 2.2.
My vibration works without sound manager on 2.2. I have even had the phone turn off due to low battery and the vibration works once the phone is back on charge

Generally it's the first thing they think of to try, regardless of the fact it means you lose all your data.

That's what I think too. I will hard reset the device after my holiday and will take care of a backup myself. If this doesn't fix the issue I'll send it to HTC...
Bad Vibrations
I've noticed a problem recently, that I get vibration when the phone rings with an incoming call, or when I switch to vibration profile, and the handset also gives 'haptic feedback' when typing etc, but no longer vibrates when I receive text messages or emails, despite soft resetting, de- and re-selecting all the relevant options.
Running 2.1 on T-Mobile, can't tell you what software I've got on it as I stood on it and cracked/trashed the screen earlier today - phone still running, receives calls, seems to be receiving emails, but can't read anything at all on the screen.
On a side note, does anyone know how to get data off a running Desire with an unreadable screen?! I can't get it to sync with the PC Sync software because I can't get it into sync mode from the touchscreen menu
Phone is set up to backup to memory card, so I am now wondering if I can use that card in a replacement handset to restore my data to new phone?
Sorry for hijacking the thread a little! Ed
Hiya folks,
Just wondering if anybody has been experiencing random reboots on the OP3. Have been experiencing em on 3.2.1 and 3.2.2 about twice a day since I got the phone four days ago. Tried a cache wipe/hard reset but to no avail. Haven't been able to reproduce the reboots. Just happen at completely random times, while writing an email, making a call, or connecting to the car Bluetooth. Phone is perfectly responsive and stable otherwise!
Have asked Amazon for a replacement, but I'm wondering if this is something that's been noticed by anybody else. No mods done, completely stock. Running dual sims (Vodafone and Jio VoLTE).
Attaching a screenshot of how the battery page shows the reboots.
Yeah, they happen for me periodically. Not nearly as often as yours though. Mine is maybe once or twice a week max. But yes, slightly annoying.
Phone is completely stock, locked, unrooted. Running 3.2.2.

Haven't had a single random reboot yet, had the phone for about a month now. Started with 3.1.3, then 3.2.1, now 3.2.2, rooted, running xposed (not a lot of modules).
What are you doing when the reboots happen (an app issue)?

It's been all over the place, but often when the screen was actually off! The way I would know would be I'd pick up the phone and see that it asks for the PIN post reboot. If it helps, I've enabled encryption. I also have a work (exchange) email account set up as a device admin
I know there's ways of investigating this with logcats and last_kmsg, but I've had the phone 4 days and I cant imagine why it's spontaneously rebooting while doing literally nothing. Seeing as hardly anybody has had similar reboots (on XDA/OnePlus forums), could this be a hardware issue at all? I could possibly try reflashing the entire phone, but that would essentially be the same as a wiping data/cache, right?
Here's an idea - my LTE data/VoLTE is extremely spotty (on Reliance Jio which is in a beta test stage) - disconnects and connects VERY frequently, could that be triggering reboots at the baseband level? Now throwing ideas at the wall!

Mine had random reboot issues recently on a trip. It only seemed to happen when I was using Google navigation combined with listening to music on my bluetooth headphones. I haven't tried that combination since the trip and haven't had any reboots since then.

same issue
the reboots are random, and i could only know that the phone has rebooted itself if it ask for a pin upon scanning finger, went to service center and has OS flashed, but the problem still persist, for me some time when the phone hangs, some kind of pixels form on the screen, attaching a sample photo for reference, anybody experiencing this issue or am i the only one, and today the phone has completely stopped working, it is not switching on.

Wow that is substantially worrying, and almost certainly not just a software issue I reckon. Try getting a replacement maybe? - or atleast ask the service folks for a mainboard replacement. Anybody else with reboot issues?
Doesn't really seem to be an OS bug, unless it happens in very niche use cases which I don't have anyway! Getting the replacement on Tuesday, fingers crossed for that one!
My friend and I both got a one plus 3. He does not have this problem but I have.
The reboot is random but usually happens during charging. Sometimes it even turns off.
I have tried to ask for a replacement but they rejected me. Still communicating with the support staffs

Went to service center in Gurgaon, getting a replacement for motherboard, as oneplus policy doesn't give replacement handset, have to SETTLE for this, i dont know how many days this whole process is going to take, will update you guys about it when i get the phone back.
I have the same issue, random reboots usually when screen is off.
3.2.1, root + xposed... for me it started with 3.2.0 update

I experienced a similar scenario twice, only seems to happen on long trips, 3+ hours. I was using Waze with Plex streaming audio over car Bluetooth. I have not had this on shorter trips, 1-2 hours. I'm typically plugged into the dash car charger. Otherwise, haven't had issues. Never rooted 3.2.2.
Situation Update
Got the replacement OP3 on August 9. Have now seen 2 random reboots since. Once while paired to the car Bluetooth, once after finishing a call.
I have till August 19 to decide whether to keep this device or ask for replacement number two! Overall, the reboot situation is a lot better on this device, but I can't help wonder - why any at all?
Seems at this point to either be a bug with the Bluetooth implementation AND/OR with the dual SIM functionality where repeated switching between SIMs for every call. (I use one SIM for calls and texts, another for data)
Can anyone confirm the situation on a custom ROM as opposed to stock? I'm running stock 3.2.2
Aaaaand now we have an ota claiming to fix 'auto-reboot issues' - 3.2.4 :laugh:
The reboots were so sparsely documented compared to the other stuff that I ended up getting a replacement for a s/w issue!
Anyway - you folks reboot free now? Post results with 3.2.4 please
I had three back to back random reboots while using Google Maps and Amazon Kindle in the background. Weird.
I've yet to have a random reboot on 3.2.4

Had several reboots while driving and navigating on google maps one after the other. Maybe it is to do with the GPS sensor but its annoying coz you need it most when u r navigating turn by turn

Agree. It happens only when I drive with gmaps running on background. When the screen times out, the phone, instead of shutting down the display, goes to hard reboot.
I've never had this issue until I moved to the latest update. Weird. Annoying.
I had my first reboot a few hours ago (with 3.2.4). I was connected to Bluetooth in my Car. Noticed it, as my car told me that mein Phone is now connected. No gmaps or something with GPS runinng.
Looks like Bluetooth is the Problem.
Sometimes, not always, when I restart my phone, things get a little crazy and somehow they must be all related. It happens as often as approx once a week. What happens is the following things:
1- I get an email from Where's My Droid that my SIM card or phone number has changed
2- Network-provided time zone changes to Central European Summertime
3- Wifi calling is turned off (however this doesn't normally stay on for some reason)
4- Visual voicemail in the phone app is missing despite still being turned on
5 - APN is not selected (the circle next to Verizon is empty aka does not have the blue dot in it)
I am on 7.1.2 and rooted. Does this happen to anyone else and is there any fix? What could be the cause?
Edit: I doubt this is related, but since I am looking for general feedback for strange bugs with my phone...
Another thing that happens is sometimes while using my phone, apps randomly reload (lack of a better word)
By reload, what happens is the app does not fully close and reopen. What happens is the app remains open ("heading" bar at the top remains) but the rest of the page I am on goes completely blank and then returns with any previous changes undone.
So say I was writing an email in gmail, the red bar at the top with the back arrow and trash can, etc. stays while the rest goes blank and any text I wrote will be gone and I have to start from the beginning. Usually when this is happening, it continues to happen repetitively for a little while. Eventually it just stops on its own. It does not seem to be related to any specific app (since it happens with a bunch of apps) unless maybe it is related to something like Swype keyboard that is always on.
Does that happen to anyone else too? What is causing this??

Hi everyone,
I have 2 Galaxy S8+ from Verizon and here are my issues:
Past issues:
One of them did not come with the Galaxy Apps store (Not the plays store), and that phone also experienced the DQA issue
Current issues:
If I turn on Fingerprint gestures, the fingerprint sensor will stop working, this was an issue I had from the day I got the phone and has continued even through the updates. Here's a thread I made about it a while ago : https://forum.xda-developers.com/galaxy-s8+/help/fingerprint-sensor-t3595614
My internal speaker has detached, or at least I think that is the issue, as sometimes when I am in a phone call and shake the phone just a little bit, it will either start making a weird buzz sound or completely cut off the sound. Shaking it again will fix it, that's why I think it's a physical issue. I haven't dropped my phone and just in case I ever do, I have a case and a screen protector on it, and neither of them (phone, case, screen protector) have any damage marks on them.
The Biggest Issue: Currently this is the most annoying bug I am experiencing is that whenever I go to lock screen and security in the setting app, it crashes the settings app. I also can't use the search function in the settings app, as it crashes the app withing a few seconds. The lock screen and security is the only menu in which I experience this, I am 99% sure this is due to me turning on Secure startup. I had it turned on a few days after I got the phone and it worked great, I had to turn it off once, about a month ago in order to get a quicker boot. After that I was experiencing issues turning it back on (meaning I turned it on, rebooted the phone and it would not work) , after some persistence, I was able to get it to work and it has worked and still works.
One thing to mention is that I had done the most recent system update, I am not sure this issue was caused by at, since the inability so search in the setting menu has happened prior to the latest update.
I have tried everything other than a full factory reset (wiping all cache, wiping apps cache, reset setting, reset network settings), which I refuse to do, It is absolutely unacceptable for me to pay this much for this phone and have so many issues with it, I have factory resetted my phone (Samsung's recommendation) in order to fix the first issue listed above, multiple times and it did not work.
At this point I really don't know what to do, Samsung support has been useless in this, I don't wish to replace my phone right now as I need it to much to even give up for one day, If anyone has any advice/fix other than factory resetting, I'll happily try it.
Thank you,
GGgamer16
Sounds like a factory reset is needed. I just tried all you mentioned with zero problems on the newest update w/ navbar options and experienced none of that. Speaker problem is most likely hardware related.

You try changing your WiFi channel? Using 5ghz or 2.5ghz? I use Wifi 100% of the time I'm home and never have any issues with disconnects.

Yeah I have tried changing channels. It didn't matter. I'm on 2.4 GHz.
I found a possible fix from another forum. I changed my wifi encryption from wpa2 AES/tkip to wpa2 tkip only last night and was rock solid after that point. I didn't have any more wifi issues... Just wanted to mention this change for other people. I usually got 5+disconnects every night. I'm gonna try just the AES option tonight and see how it acts.
Hi, i have a big issue with this phone, i bought it like 2 weeks ago.
Since the 2nd day of use, i started to experience this issue, sometimes and usually when im not using wifi but mobile data, the screen goes to lockscreen, if i try to unlock it will lock again and that happens a couple of times, maybe 2, 3, 4, 5 times, sometimes i have to press lock button and try again. its really annoying, because somtimes it doesnt happen in a lot of time and then after 1 hour in the street and while im using it it locks and unlocks like crazy.
i did a soft factory reset but didnt work, i even tried in safe mode and it still happens.
yesteday i noticed that it even wakes up for no reason, that happened while i was driving in a highway, it suddenly wakes up like if i touched it, i disabled every feature about auto waking (like 2 touch, motion detection) but it still happens.
the only thing that makes it stop is if i switch airplane mode, so i guess maybe its something related to network (not wifi or location or mobile data because i disabled those and still happened), but when it is in airplane mode it will work fine, obv thats not a real solution.
i tried disabling and uninstalling a lot of apps but i cant figure out whats making this, im pretty sure its software problem, something related to network but i dont know.
do you have any ideas? even if i take it to tech service it will be hard to show them because sometimes it doesnt happen in hours.
anybody has an idea what could be causing my phone to lock for no reason while using it on the street?
Your phone gone kaboom
I have same problem, the problem is caused by the weak signals,which means that your phone connectivity is constantly changing, for example on a highway or in a basement. Solutions I have none, just waiting samsung to make a fix
Yes, thats exactly the problem. When signal is weak the phone locks or unlocks. I asked for a new phone at the store and they gave me a new one.
