Question Help diagnosing a issue - Samsung Galaxy S21 Ultra

My S21 Ultra has been suffering a minor screen glitch mainly on the lockscreen but sometimes appearing in applications.
I thought it was a hardware issue but after a screen replacement it is still happening.
Hopefully some S21 Ultra owners can help me diagnose the issue.
How to reproduce the issue:-
Make sure dark mode is enabled
Make sure color pallet is enabled
Make sure QHD resolution is enabled
Make sure lock screen is stock live wallpaper
Now when phone is locked, press lock button on & off 10 times one after the other.
Do you see glitch lines across the time on lock screen?
Thanks in advance guys!

not sure what you mean, I don't see anything.
share the device model number and the software version it's on please.
also, i suggest you submit error report to samsung members app > get help > error report after reproducing the issue (would be best if you take video recording or a screenshot of the issue when submitting ticket).

Attached a video for better understanding of the issue.

Just my guess, so don't take my word for it since I might be wrong... but I'm guessing it's due to how the display powering on is programmed, which area is supposed to light up first and the animation of how the screen powers on is causing that 'glitch'.
I also don't think it's a hardware issue but rather something more software related that needs to be modified.
One other possibility is the charge buildup/flow within the hardware wirings that end-up resulting temporary spiking in LED lighting up to the area that lights up first. (again, I am very much speaking hypothetically. By no means am I an expert in this area)

Had Samsung take a look at it, phone passed software diagnostic after a reflash from themselves, then they done a full hardware replacement, motherboard, screen, battery, the whole phone basically, issue still persisted, they deemed it a OneUi 4 issue as the display phones on OneUi 3 didn't have the same issue, guess I'll just wait for a OTA.

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive
Hi All,
I got an issue bothering me since I bought Xperia X Perfomance (F8132) Mid June.
The auto rotate function failed after a while but everything goes fine after reboot.
When it fails, I use "Xperia Service Menu" -> "Service Tests" -> "Accelerometer",
then all X,Y,Z are zero and the ball just sticks and freezes at mid.
I bought from Taiwan and I can find 15 more people having the same symptom with me on 2 forums
( http://mobile01.com and http://gamer.com.tw ).
Hence I don't think it's only me and it's a common issue or common yield problem for Xperia X Perfomance.
I post here because I'd like to find more people with the same issue and raise the attention of SONY in order to find the root cause (i guess it's either over-heat causes this or accelerometer yield issue) and give a patch.
Now I'm using a APP "Rotation Control" to workaround this, but all photos cannot records correct orientation data and no auto-rotate is kinda inconvenient.
For a flag-ship and high-priced cellphone for SONY this year, it is very disappointing to me. :crying:
Version: 35.0.A.1.227 and 35.0.A.1.238 both occur

I also have that problem. No more auto-rotation after a while (1-2 days) . Only a reboot fixes that

Thank you for letting us know.
It shows it's not a regional FW issue but a global HW or FW one.
I wonder if SONY knowing this. If not, we need to address this and push SONY to work it around.
And if it is not workaroundable, SONY will have a big problem.
I have the same issue on my Xperia X (F5121) bought in Sweden. Haven't checked the accelerometer but the behaviour is the same and reboot is only fix.
I have not had any problems with auto rotation, my accelerometer works fine but my touch screen is messed up

Can you specify "messed up"? I've had issues with the touch screen also, mostly that it registers a tap while I'm scrolling resulting in involuntary tapping on links. Also it often takes a while to start scrolling, as if the screen has a hard time recognising the swipe.
I have the same problem. The accelerometer stop working 15 minutes after reboot.
Help me verify if is caused by a third party app or not.
Use your phone in safe mode for a while.
I'm from Hong Kong, the accelerometer and its auto-rotation of my x performance has the same problem that it won't work until i reboot my phone.
I dont think that is caused by a app crashing when the problems occuring in all around the world.
The issue didnt come to me when I was not yet update to 35.0.A.1.282. Please notice this problem SONY. It seriously affected the satisfaction from user of the phone from your brand.
There is a topic on the Sony support forum - see here: http://talk.sonymobile.com/t5/Xperia-X-Performance/Accelerometer-stops-working/m-p/1158490#U1158490
At least they are aware of the problem. As soon as it happens again on my phone, I will send them my logs. I will report any development...
It seems that I uninstall the AR effects in my phone and reboot, it works again
Rotation fails
Hello guys,
I have the same problem. Yesterday it worked fine, but today, the auto rotate don't work. Very disappointing. Only a reboot can help but not every time.
Sony has to do something with it.
Gyroscope/Auto-Rotation Issue
Hey everyone,
I'm also having this same issue, but only since the most recent update from late September. When trying to make a pic display as fullscreen by rotating the phone, nothing happens, unless I reboot the phone. Then within day or two, it starts happening again. When I go to camera it loads up and STAYS in landscape mode, no matter what I do, even closing it out and clearing out the cache & force stopping it then reactivating it. It seems like a software issue that Sony needs to address PRONTO!
It appears another thread here on XDA is dealing with the same issue. I tried shenlong85's idea and it seems to have fixed the issue, but I need another day or so to make sure. If you don't hear from me by Sunday (10/23), assume it's been fixed. Hopefully the Nougat update we're all about to get any day now will permanently fix it!
The memory uninstall updates only prolong the issues. Seems like the firmware issue earlier on.
Nougat... When are u coming?

Well, we'll see. I am giving my XP 'til Sunday........if no more auto-rotate issues by then, then I will consider your idea to be gold. lol Of course, once we get Nougat, I'm hoping it will ensure that the issue never comes back period. As of this time, the issue has NOT returned.
I bought my Xperia X Performance from Kogan who sells imports in Australia from Asia and I have the exact same issues with my orientation and touchscreen. However my jumpy touchscreen only seems to occur while charging.

I tried shenlong85's idea, but less than 24 hours after trying it, I switched my phone from Portrait to Landscape to view a 16:9 widescreen pic I had in my Album, and it WOULD not auto-rotate the pic. So unfortunately this "trick" doesn't work either.
Just have to hope Sony includes a fix with the Nougat update we're about to get any day now from them.
I'm noticing now too that once the Auto-Rotate function stops working, so does Smart Call Handling. Have to swipe screen once again to take calls. Hurry up Nougat!! lol
I'm having the same issue and the only help I'm getting from Sony support is to factory reset my device :\ I'm hoping Nougat makes it's way to our devices soon. I really like this phone and this is a pretty big issue to have.

I agree Spencer. And yes Sony Mobile told me the same thing. I'll do a repair (which yes, includes a factory reset) only IF Nougat doesn't fix it. They say we're getting it "in or close to October", so I'm guessing it's gotta be coming any day now. Hopefully they include a fix with Nougat though and I don't have to do that. Getting tired of this BS with Sony. My Z3 had an issue where if I turned on Stamina Mode, it would 1) mess with my MMS (group/pic/video) text messages.........you don't know how many times I had to ask ppl to resend those to me and how much that sucked lol 2) Cause a "random" battery drain. Only fix was a factory reset. I FINALLY got wise and realized it was SM and kept it off. Found a great app called 360 Hibernation Master that did what SM was supposed to do but better, MINUS the buggy BS. But OF COURSE it doesn't work on any X series phone (at least not my XP), so I'm stuck with SM now. At least Sony Mobile FINALLY fixed that bug with SM so that's not an issue anymore. lol
It is a big issue, and it makes me not want to keep buying their phones.

Problem with the Front Facing camera.

I was wondering if anyone else had this issue with the front facing camera. There's a couple people that had this issue as well, check the
mentions for SamsungSupport on Twitter a couple days back(at the time of this post)
There's even a video of it in action: https://twitter.com/Hired_Assassin5/status/918633351510200320
As you can see at the top, there's some major discoloration going on. It's almost like a negative image.
https://i.imgur.com/2ipVzgS.jpg
I got the phone on Sep 15th, release day. The camera was working fine up until around Oct 5th that I know of. Taking selfies with the dog, etc.
Well, I opened it up on the 12th, haven't used it for a while, and I noticed that issue you see in the first image. I contacted Samsung and they had me
go through the whole troubleshooting process, all the way to me factory resetting my device. Factory Reset, then skipped all the setup wizards
and went straight to testing the camera. Issue is still present!
So the next day, I went to my carrier store, they said they never seen that before. So they're ordering me a shipment to replace it, possible defect.
Well, that night, I decided to try and look deeper into the issue. Flashlight on camera lenses, didn't see anything. Then I remembered from previous
android phones, there's hardware codes you can enter into the Dialer, so I input *#0*#, which is the hardware testing screen.
It looks like this:
https://i.imgur.com/RhJD4WJ.jpg
So obviously, one of the options is "FRONT CAM". I thought I would "test" it. I clicked on it, and it was working fine! I said oh sh!t, WTH.
This is the screenshot of it:
https://i.imgur.com/2BiaA7U.jpg
Then I took the picture as well, and it turned out just fine, like a normal camera. Well when you tap the screen again, it backs out, and switches
into a different mode, or something. And well sure enough, that issue I was having in my main camera app showed up!
This is a screenshot of it:
https://i.imgur.com/kGgJDD1.jpg
Now this is where I'm wondering if the Geniuses and good people here at XDA can figure out.
If you notice in the first screenshot of the "test" https://i.imgur.com/2BiaA7U.jpg
It says SUB AP at the top left....
Then in the next one, the defective one or whatever https://i.imgur.com/kGgJDD1.jpg
It says SUB CC.
Does anyone know what those are, or what they stand for? And if possible, how can I get my camera app to go back to using the correct mode or whatever that is.
This issue happens in all camera apps, the Samsung default camera app, play store camera apps, etc.
Thanks.

I'm not having that issue *knocks on wood*
But it doesn't sound like a hardware issue though.
Sub AP, Sub CC are probably different Samsung settings not available to end users. Any advice I'd give is to back up, hard reset, test if problem still present, if problem fixed restore data.
When does the problem usually happen, in bright or low light?
What if you use the front camera "flash" does it still happen?

I originally thought it was a hardware issue, but seeing it function normally when I did the diagnostic testing, I knew it had to be
something that triggered the software to not work correctly.
the issue is still present no matter what settings I change. Changing resolution, flash on/off, picture size, HDR on/off/auto, all the settings
I can find, the issue is still exists.
EDIT: Is a hard rest the same as a Factory Reset?

Dam, that's unfortunate. That's 4 people now that have had this issue. I wonder how much worse it will get. Hopefully the new replacement doesn't have this issue.
It's weird because it was working fine for a few weeks, and then something happened. Not sure if it auto updated without me knowing and caused this issue.

sounds like they're sending you a replacement. make sure you are satisfied with the replacement because they might send you a refurb.

Nope, Samsung never got back to me. I just went to the Tmobile store and they were like, yep, never seen that before. So they overnight me a new one.
I just begun to have the same issue on my phone and I'm not happy after spending 1k on it. I'm going to my career tomorrow but unfortunately don't know I this will be resolved. Please Let me know what Samsung did for you.

If you did not mistreat the device, dropped it or fiddle with system settings or something of the sort, warranty is the all time solution for these problems
Hey my note 8 front camera just experienced the same issue. I've talked to Samsung support, and frankly it seems like it is a hardware issue. It is recommended that you use Samsung Support to make a service request. Free shipping both ways, so if you can live without your phone for a week or two (or have a backup phone to use), that's the route I recommend people going.
Original Problem:
MENU / COMMON APPLICATION ( NATIVE) - CAMERA / VIDEO - CAMERA EFFECTS NOT WORKING
Problem found:
FRONT CAMERA FAIL

My front selfie camera has the same problem!

already try Wipe cache partition and hard reset but still facing the same issue..
but if i use front camera for video call thru whatsapp it's working fine, but yet again if check thru *#0*# for Front Camera it's Camera Failed..
is it hardware issue or FW issue ?
Front Facing camera has double image
Has anyone found a fix for this issue yet? Mine started this issue last year and I haven't found a remedy for it yet. Ugh.

Samsung Note 9 - Display Discoloration & Overheating

Who else are facing the same problem ?
1)Initially, when I unlock phone by pressing power button the display was changed to dim colour(mostly yellowish) and with horizontal lines displayed when the brightness is below 50%. After tried with multiple times pressing on power button the display came back to normal.
2) Next stage, it's not solved with power button. I have to keep my phone aside for some time to get back to normal display. It's been 15 to 20 min then.
3) Now, I would get normal display only in morning. Else, I need to keep my phone idle without touching for at least 4 to 5 hours. I've also changed screen power off time from 30 Sec to 10 Minutes. So that my screen wont turn off and I can keep the normal display. If I forgot to use or kept aside more than 10 min then my screen would go off and display would gone again and irritation starts with that discoloration problem..
4) If display changes to yellowish to reduce the horizontal lines problem I need to increase the brightness to 80 or 85% but this causing my phone with another problem "heating issue"
Samsung haven't responded on this issue yet, how could we bring up the issue and get the proper resolution from Samsung.
This happened after last March update installation?
What note 9 do you have?
Probably not a hardware fault if it happened after recent software update.
A number of note9 affected although samsung seems to disagree at the moment.
Hello,
I also have a problem with the display after waking up with the POWER button. There are tinted colors distorted and some stripes like dim lines and slow refreshing. Everything started after updating to Android 10. In fact, when the display lights up incorrectly, it starts to heat up from the bottom. Putting the smartphone aside for a moment or cooling down causes the display to work correctly.
Workaround? I turned on Active Display and first knock to activate it, then the display lights up correctly and then I unlock the screen and use normally. It is known that battery consumption increases. Of course mine is Exynos.
hi guys,, i remember a similar experience sometime back.. try this. if u have turn on the proximity sensor i mean the advance feature where the phone screen doesn't turn on while in pocket , switch it off and restart the phone and see if the problem still exist.
i am having same issue

whats the firmware version u are having now and phone model?
Try wiping the cache partition in Recovery Mode. If that doesn't work then back up your device and manually reinstall the OS back onto your device.
Im having the exact problem. I flash LineageOS and it worked by max brightness then back to auto. I installed brightness widget to max brightness and back to auto everytime I turn on screen.
This issue is popular after March update. I tried everythings you mentioned above, reset, flash new firmware, even April update, wipe cached, flash cooked rom, heat screen, turn off features, disable gpu overlay, etc... Samsung Vietnam guaranteed can fix with new screen but I'm out of warranty.
I dont have any issues us unlocked snapdragon xaa model on latest android 10 version.
Can we confirmed that a screen replacement fixes the display problem or is it still a software issue

No one knows what is the exact cause here, its noticed in many devices right after this March update but few are noticed months before. But, now the problem came to many users at same time. So its been brought up by many tech blogs, websites.

I'm having the exynos version too but with ITV (Italy) firmware ...never had this problem and now I'm on April's version after March's version.
This looks a little bit like what happened to the S5 years ago when after 1 and a half/ 2 and a half year's the screan began flickering, having green spots or lines, randomly didn't go on with low luminance settings since it completely died....a lot of people said on forum's that it was the screen and a replacement solves, but when it happened to me years ago the Samsung assistance center told me that it was another component (never told me what it was) causing the issue and once they changed it , they solved the problem.
So, after my experience with the S5, don't know what to think now for what is happening to some guys even if I think that this issue might depend with something happening after marchs update because for the too many people having it after the update, coincidences are not credible.

Yes, many people were facing this problem and how many times we have contacted the Samsung they are behaving like they just hearing the issue for the first time. Just created and posted the link in Members app and 67 members joined so far. Everyone having the display problem out of nowhere. All of them on out of warranty except one or two. Still members app floating with the display problem messages.
Display issue got noticed in S20 too but they immediately released the security patch and solved it. Don't know why they were silent on Note 9.

Black crush / gradient banding issue in samsung note 9

Hello community!
I recently bought a samsung note 9 out of the love towards the note series. But, after 2-3 weeks of usage I started noticing that there are some issues in displaying darker shades of black. The gradients of blacks are not shown properly. Instead, bands are formed in different shades of black. I searched internet and found that it is called black crush. My display is perfectly fine and it is appears like some firmware/software problem rather than a hardware issue. I also saw many people complaining about the same issue with samsung premium phones like S9+, Note 8/9 etc. But it is very surprising that there is no result for black crush or gradient banding in xda forum for note 9.
Please help me here. I wanna know if this is an issue of my piece only or is there anyone with the same issue. (Do check your phone twice before saying no. You might miss to notice it). It is so sad that a premium phone like note 9 is having an issue like this. I also read that even the advanced note 10 also face this problem. So even an update sounds foolish. The black crush isssue is really annoying. Once we notice it, we'll see it everywhere and we cant unsee.
I can't put screenshot to explain as it is a processing problem. You can search google to understand black crush or I can take a picture, if needed, of my display showing it.
If the problem really exists, I think it is high time for Samsung to have a look at it.
Is it on Mar security patch or newer?

Im in the latest security patch (1st September 2020). Is there anyway to get rid of the black crush problem? Would it help if I try installing a custom rom?
I can't tell if custom rom could fix your problem or not but those with display discoloration issue mentioned that their problem haven't go away with newer security patch(Aug/Sep).
If you've no plan in using samsung pay, you could try custom rom but rooting will break this function forever. There are workaround for other functions(at least in rooted mode), but not for samsung pay.

I was thinking about installing another OS. But, I'm not feeling to do it, as rooting permanently trip Knox. Do you know if the black crush issue is a h/w or s/w problem? Is there any fix for this? Will rolling back the OS to any previous version can help removing it?
I don't know if it's s/w or h/w but most people with display discoloration issue(not sure if similar as yours?) said s/w. Better just wait for newer firmware base. Those security patches probably with old bootloader/base that's why the screen issue persists.

It appears to be a software issue for me too, rather than a hardware one. Thanks for your advice. I'm gonna take it and wait for some time for an update from samsung, without unlocking the bootloader.

Green screen bug

Hi everyone, I know this may be a rather silly question, but from what I saw, not all devices (S9/S9+) were affected by the green screen bug due to the software error. Has anyone tried to "catch" software from one of these unaffected devices and test it on one that was affected? So far, we still have no official statement from the company and a problem with cell phones. I tried several roms and they all gave me the same error on the screen :/

I've installed OLED Saver to go around this bug.
I wanted to learn how to downgrade the version, this happened after the Sep 18 update for me.

Bloody annoying, only way to solve it for now is to set always on display to on, then when screen is off you have to tap screen to come on then unlock with fingerprint, phone screen is now perfect.
This proves a software bug all along.
