Always on Display doesn't stay on - Samsung Galaxy S21 Questions

I purchased my S21 about 5 weeks ago and I am not sure if I have been experiencing this issue since I bought it but in the last week, I have noticed this issue. When my phone is locked, the AOD will either show for a few seconds to a minute or just won't show. I've ensured it is set to always show, power-saving not set to turn it off, no Bixby routines and any updates are installed for phone/AOD. I've even factory reset my phone and removed the case and screen protector and the issues are still persisting. Does anyone else experience this issue?

Disable all power management... it screws up all kinds of things.
Does AOD show if you tap the screen?

I have disabled all power management that I am aware of and still experiencing issues. I've set it to show on tap and while it worked the first time, subsequent taps do not show the AOD

Sounds like a firmware glitch or the flash was corrupted.
Double check all AOD and screen lock settings.
Try turning AOD always on.
Try disabling screen lock... a lock out is the last thing you want anyway.
Play with it... Android's wuv attention.
The case or screen protector won't do this more than likely.

I normally use AOD always on, I'd tried the tap on the option to test. Going to try flashing it today to see if that helps despite the factory reset not helping.

So I've flashed the stock firmware back onto my device and the issues are still persisting. I've contacted support through the Samsung Members app and it's been escalated to the Research and Development team and am just waiting to hear back.

Did you update any Samsung apps after the reload before testing it? Go with the factory app loads.
Try disabling the lock screen... they tend to end up locking out the intended user anyway, sooner or latter.
If no one else is having this issue it very well maybe a hardware issue.
Did you ever wonder what happens when one or two micro transistor junctions out of the millions in a phone fail? Yes, well...

Unfortunately I can't recall if Samsung apps updated before I tested. I've already factory reset a few times so I'd rather avoid that for now. I've noticed the issues occur when using auto-brightness on AOD in lower light settings. When I say lower light, I mean in my study during the day which I never experienced issues with on my S20 FE. I've sent a report to Samsung Members and am waiting on them to come back to me.

Did you ever get this fixed. I have the exact same issue on my s20 ultra
Edit: Nevermind just fixed it after 3 days troubleshooting. Oddly it was the the disable AOD while in power saving mode that needed to be disabled even though I don't use power saving mode. Samsung never seem to amaze me with these dumb persistent bugs.

Glad to see you solved the issue. I'd already confirmed this setting was off for me. It's still happening. Looks like it's something to do with the level of light detection as the issue only happens when I have auto brightness set for the AOD. The problem is it's not even that dark when it's happening and never occurred with my S20 FE.

[Q] HTC Amaze Screen Goes Black After Ending Phone Call

I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.

Screen won't time out

After my phone is running for awhile the screen won't time out, a reboot will fix it but after some time the screen won't timeout again. Also if Quick glance is activated, while the issue is present, the screen will turn on, start to dim and then the lock screen will show and stay until I shut it down. Maybe an app is running in the background and keeping it from shutting down? This is when the phone is not charging so it's not the Stay awake setting. I've also turned various settings on and off as well as changing the screen timeout, which is now set to 15 secs, and the problem still persists.
Anyone with this issue?
I've seen some (Issue 37974) with the GS3 posting about the same issue but never saw a resolution.
Any help or insight would be appreciated.
I've noticed this but it usually was an app that kept it running.
From the Homescreen, try holding down the Home "Verzion" button for a few seconds. Click "Remove All" and then see if it times out. If that doesn't work, try clicking "Task Manager" instead and closing all Active Applications.
If either of these do work, then when you notice it again, be more selective in which apps you close until you find the offending app. I have a few Sound Engineering apps that use the microphone and one of them forces my screen to stay on. I'm assuming to access the mic hardware. It seems to run in the background even when I "close" the app.
I've done the remove all and nada but I'm adsuming it is and app too...
Thanks for the reply...
It must be Stay Awake in developer options that is causing this bug. As stated a reboot fixes the issue temporarily, after the reboot the Stay Awake option gets turned off on its own, If I turn it on again the issue appears again shortly after. So somehow the Stay Awake option must be getting messed up and keeping the screen on even when not charging.
My workaround is turn off Stay Awake and Use Tasker to keep the phone awake while charging. Not what I'd like, I'd prefer the system work correctly, but it works for now.
Thanks
first off are you using a different keyboard other then the Samsung one ?
i had this happen to me using Swift.
just reboot your device and you should be golden.
Dont know why the keyboard would do this to the phone but thats what it was and all i did was reboot and Timeout works fine...

Don't think the keyboard is a major issue with this. I've had this issue both when using swift and just the SS keyboard. I am more inclined to think like the other poster said that it has to deal with SmartStay. I haven't tried turning it off then rebooting, going to see if that works now. It sucks because toggling SmartStay is really useful, but i'm concerned with burn-in and especially with a battery that lasts 10hrs+, that could be an issue.

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem

Always on Display (AOD) issue

Is anyone else having issues with AOD turning off even with slight darkness. For some reason my AOD keeps turning off even though there still some light in the room. It used to stay on when I wake up at 6am when there some sunlight but now it just turns off. I have to point the phone directly to the light sometimes to get it to turn on. Don't have any screen protector that is blocking the light sensor and seems to function correctly checking the debug mode (*#0*#). I have to reboot the phone to fix the issue but after a few days it goes back to being wonky.
yeah, i updated it via Samsung Galaxy App store, then did a data clear in the setting menu and now it works. But mine did the exact same thing.
clearing the data still causes me the problem.. Only fix for me is to reboot the phone =/
Do you have a screen protector?

I have a screen protector but have all the cutouts that isn't blocking the proximity sensor. I've tested the sensor in debug mode and no issues at all.
what was updated or installed recently that had this started happening with. It may be an app that introduced a bug. Did you try and see if there is a AOD update?

what screwed it up was the AOD update (go figures ).. I reverted back to the original before the update but somehow it's broken now. As mention it works like it should after a reboot but after a few days it becomes all wonky.

General Why must unlocking my phone be so cumbersome?

The simple user experience of unlocking the device on is so bad on Pixel 6. There's just no winning option.
Smart Lock randomly kicks in, so I can't be sure that a single tap of the screen will turn on the phone.
The fingerprint sensor sucks, and requires a tap on the screen just to bring it up. And sometimes I don't even get the option to use my fingerprint.
I don't even like the single-tap gesture to begin with. It means I'm accidentally turning my screen on all the time just when carrying the phone. It almost started a call with my deadbeat father, who I haven't talked to in 20 years
I could go with no screen lock but then I'm locked out of several key features (like viewing my account passwords). Also, pressing the Power button at all on a phone this big is cumbersome, since I then have to reposition my entire hand to go from pressing it to then interacting with the screen.
I'm already rooted because I absolutely needed the Back button to be on the right side. Now I'm hoping modders can fix the unlocking experience because it's the next big issue in my mind.
The fingerprint scanner is actually very good if you set it up right, and will always be displayed with always on display... No tap required. Problem solved

This is not my experience at all. Sometimes I get a fingerprint sensor icon. Other times my phone is unlocked via Smart Lock and I get an Unlock icon in place of the fingerprint sensor. Other times I get a Lock icon indicating Smart Lock is expired. Other times I get no icon there at all.
If the fingerprint sensor is there and I'm on the dimmed screen, sometimes it'll just light up and deny, and other times it won't even acknowledge that I've put my finger on the sensor.
If the Unlock icon is there, it requires a tap to unlock (no holding!). So that means I have to actually look at the screen and discern which icon is there to know whether I need to tap or hold.
And Lift to Check Phone would be even more problematic for me, since I'm trying to avoid accidental screen interactions and this would only cause more.
On all my other Pixel phones I just touch the back fingerprint sensor and the phone is on. I don't have to think about a dozen different possible states the phone could be in every time I want to turn it on.
Have you tried to recalibrate it via the Pixel tool thing Google has?

It sounds like smartlock working as intended (which I find useless, and poor security). It will give you an unlock icon instead of the fingerprint. Maybe you simply don't want smart unlock, which is more useful for password only. This seems like more of a matter of figuring out what features you want to use.
If you changed the Animation Scale in Developer Settings then the AOD fingerprint icon can disappear.

I never used to use Smart Lock, but on this phone it means I don't have to deal with the inconsistent fingerprint sensor as often.

Try setting up the fingerprint scanner again, slightly moving your finger with ever press during set up to get every angle and view of the print. It's been pretty much perfect for me. I suppose Google could have helped instruct people to do that better in the process.

I just restarted my phone, and then repeatedly unlocked and locked it (sometimes by fingerprint, sometimes by tapping). By the end of the video, the fingerprint sensor icon disappeared completely and wouldn't come back until after another restart:

This is just one example of the inconsistencies. I haven't changed the animation settings either.
I did see it happen a couple of times in your stream. I don't recall seeing that on mine, but I haven't been looking for it. The only other thing I can suggest is make sure you have the latest updates and/or factory reset.
Edit - I tried to replicate your stream, and the sensor showed in all 30 attempts for me. For whatever it's worth, so might be something specific to your device, maybe settings or software issue

what are you going on about lol. this is the kind of nonsense that is so irritating. you had 100% success rate unlocking your phone. what's the problem. looks to me like it works. so what's the big deal. and then you have the gall to complain that the sensor icon disappeared after you repeatedly locked and unlocked your phone? yea. try starting your car repeatedly. see what happens with the engine.

i will just apologize and go on with my day. good luck with the phone.
I went ahead and updated to the November firmware, and wiped my data as well. Now my phone won't show the fingerprint sensor while unlocking under any circumstances. I also found an interesting bug wherein I'm still able to turn my screen on by tapping it repeatedly even with "Tap to check phone" disabled:

I can recreate this 100% of the time by just setting my phone down for a second and picking it back up, then trying to unlock it. And you can't see it in the video, but the sensor doesn't even light up the first time I touch it. This is clearly a software bug.

Guess you don't know anything about cars. You can start and stop a fuel injected car until the battery dies, and nothing will happen to the engine or fuel system. (Yes, the battery will die if you keep starting the car and tuning it off right away) Just as proof of this, most modern cars shut off the engine when you come to a stop, and restart when you let off the brake. If you're in stop and go traffic, the engine will shut off and turn on repeatedly in a short amount of time nd distance.
Now with classic cars and motorcycles, you my flood the carb with repeated starts. Not a big deal, and not any kind of damage.
The only "damage" in repeatedly starting a car would be normal wear and tear on the starter. They do have a finite lifespan. But again, not damage, just use.
