Question Display hue flickering - Samsung Galaxy S21 Ultra

I don't really know how to explain or describe this problem I am having. But while I'm staring at my screen for example in the settings menu I can see the color or the background change from one color to another and it keeps going back and forward. I tried to get screen recordings and screenshots but it does not get captured during screen recordings even tho it's happening while recording. Has anyone else experienced this problem?
Edit: I think it has something to do with the refresh rate going from 60 to 120. I noticed this because I have my refresh rate monitor on the status bar

Adaptive brightness?

So I noticed it only happens when the refresh rate goes down to 48hz. I use Galaxy max Hz app to force 48hz when its just idling. When I set it to 60hz it's fine

How To Guide 120Hz refresh rate everywhere (including YouTube) No root.

I jumped from stock CN firmware to XiaomiEU and I noticed that my YouTube running on 60Hz...this is how to fix it back to 120hz all the time. This is method gonna change you refresh rate to 120Hz everywhere including games, and it will stay after restarting ur phone
Attached screenshot
I think videos on YouTube are max 60 FPS so no real point in any higher than 60hz. That was my understanding anyway I could be well off.
I would gladly make it so that the refresh drops to the content I'm watching ( like YouTube to 60 ) but it seems to be stuck on 120hz always... that's why I set it to 90hz and it's much better now . It's a very good compromise between battery drain and viewing experience imo.
Cheers !

Correct, videos on YT are 60FPS max. However I think OP simply meant 120Hz when scrolling in the YouTube app

Nope, it doesn't work in my 11 Ultra global rom. What i did was clear the cache of battery and performance apps and it will become 120Hz everywhere. However it will revert back once restarted.
I am not sure if this will work with xiaomi devices but for those who want to test/try, check galaxy max hz

Damn thx bruh. I'm getting 120 on yt now. Was trying to find out how to get this done. Idk I came across stuff like to clear the battery app. Weird.
Anyway thx! This helped a ton!
It doesn't work really well though as after watching a video YouTube goes back to 60hz, I found the solution with forcing 120hz via custom props for those who have root
Thanks, it worked on my Poco F3
Thanks it worked on mi 11.

The swich between 120 and 60 or between 90 or 60 (when setting the refresh rate manually) on Mi 11 Pro is driving me crazy. The reason is that the screen flickers eveytime it switches refresh rate. I really need to set 90hz or 120hz permanently but none of the solutions above works for me. Is there any other way to fix the refresh rate to a given number? 60hz is too low.
You can do ot with terminal if you have root or via ADB if not

I used this app before. I now suspect that my problems with flicker started some time after I changed the refresh rate to 90hz using setedit. Anyway, I recently did a clean install of MIUI 13 (Xiaomi EU) and the flicker is gone. I use the default 120 hz mode now and get more or less the same battery life as when I used 90hz. Before I did a clean flash it did not work using ADB commands either. Even if I set both minimum or maximun refresh rate to 90 it jumped between 60 and 90 constantly.

S20 FE Amoled screen is not truly black [issue]

I noticed at bedtime that this phone's panel didn't get those deep blacks we come to expect from samsung panels, i remeber in 2012 i had the same issue with my galaxy S2, i can see the black being lit like it was an LCD panel.
black image 0% brightness at 60hz = i can clearly see the display back-light.
black image 0% brightness at 120hz = it behaves like an amoled panel should, i can't see a thing.
The phone is running the latest software, oneui 3.1 + May patch.
Is this a known software bug? I think i'll return this phone because of this.
There is no backlight in a AMOLED display.
Firmware or hardware issue.

Try clearing the system cache
Try a hard reboot
Doesn't it have variable display frequency depending on what you're viewing ie static picture vs scrolling?
Could that be coming into play?
A glitch. You can't clear the graphic driver data but maybe the apk that controls the variable rate if separate from that.
You haven't done any major firmware upgrades, right?
I haven't play with the higher refresh rate displays, pretty much love my 10+/Pie.
Otherwise...
If you're within your return window, do so.

maybe some calibration issue? however someone tested on his device and had pitch black on both refresh rate so i think thats a faulty panel.

I've not personally used an S20 FE , but am a samsung user myself.
it should be pitch black.
are you sure the picture was absolute black and not slightly gray ?
if it was an absolute black image , the screen should not emit no light at all irrespective of what brightness you put it in , since it is black.

Thanks. That's what I was thinking about. No need to send for replacement since the same is with all units. Not a big problem for me since I like to use 120hz even if it drains more battery.
I got the same issue. It seems to be a software issue, because it only happens in always on display. If I open a black image the screen comes completely black. Weird bug.
There is a setting for variable current verses pulse modulation for brightness, I can't recall what they call it. Try using the variable current setting.

I am using the samsung galaxy A 52s 5g.
It has the exact same issue, the AOD and lockscreen behave like a LCD panel with a yellowish tint when the refresh rate is set on 60Hz.
Though everything else is fine, other screens and apps.
If set at 120Hz then AOD and lockscreen behave normally.
I don't what this is.. maybe samsung did not optimise their 60Hz setting properly.

Question Adaptive Refresh Rate

Hi!
Is there any rom that provides the option of adaptive refresh rate? Is it possible to provide this option is a rom? Or is there another way to do so?
Full time 120Hz consumes a lot of battery.
Thanks!
You can enable the video toolbox for the application you want to use 120hz with and enable the adaptive refresh rate in the toolbox.
what is tollbox ?
i'haven't adaptive refresh rate....
Search for video toolbox in the settings. But yes I am seeing now that they removed that option for adaptive refresh rate.
It is kind of adaptive on 120hz, it drops to 60hz every chance it gets while not interacting with it.
This made myself and others here to lock it on 120hz.

Question Picture in Picture, Split Screen etc - Refresh Rate drops to 60Hz (EXYNOS)

Hi there, I'd not noticed this before the Android 12 update, but refresh rate appears to drop from 120Hz to 60Hz when using Picture in Picture or Split Screen views. Can anyone else reproduce this please?
You can confirm this by going into developer mode and toggling to always display the refresh rate.
Try a factory reset if you haven't already and it was a OTA upgrade...
I'd rather see if others can reproduce this first - would have thought it's a simple enough thing to test and post your results here, thanks!
Hi SSJ100, I just tested this to confirm for you, it does drop to 60hz immediately and I cannot prompt it to 120hz until I return to full screen view
Further testing, if i have video running in the background, Amazon, netflix or YouTube it stays at 120 with windowed mode on

Thanks for checking! Again though, I'm quite amazed (okay, maybe not quite the word hehe) at how no one has reported this issue in this forum (and at least one other "major" forum). If they have, please excuse my ignorance and I'd appreciate a link to the thread.
I can also confirm that this issue persists even after updating to the so-called bug fixing patch "BUKG".

Interesting how bugs like this manifest sometimes huh hehe. I first noticed this issue with Google Maps when I was navigating with it and switching to another app (which automatically forces Google Maps app to become picture in picture mode). Scrolling looks quite different and jittery - it's amazing how one gets used to 120Hz!
Have you tried the tiles app developed by a user on here? It can force refresh rates very easily and just requires an adb permission.....there was a thread the other day

There is some black magic going on with these 120Hz panels. 60 Hz never seemed to be a problem before these high refresh rate displays started popping up. I remember smooth as butter 60Hz phones (both iphones and android). But now when i use a 120Hz panel at a 60Hz refresh rate, it feels like something inside the phone is in it's death throes, coughing and spluttering - the stutter is jarring! But if I use my wife's OnePlus 6 (which has a fixed 60Hz screen), it doesn't feel so bad. It's definitely not as smooth as 120Hz but the 60Hz on a 60Hz panel feels smoother than 60Hz on a 120Hz panel. Is it only me or has anyone else had a similar experience?
I have the same issue as well..so pissed..using latest BUKG
I'm on Android 11, One UI 3 still, and when my phone displays split screen apps the refresh rate drops from 120 down to 60.
This must be some battery saving feature, because If I toggle performance mode (processing speed) from the drop down quick menu, the fps shoots back up to 120 in split screen.
So an easy fix if you need 120 in split screen.

Yes, that seems to "fix" it for split screen. However, it doesn't resolve picture in picture fps drop to 60Hz.
Hmm must be an Android 12 thing. I'm sat here typing this with YouTube playing pip and the screen is holding 120fps even with my finger removed from the screen.
I did try Android 12 when the public version was released, but didn't like it, so downgraded back to the last version of 11, with a clean wipe.
Ok something odd going off, my screen seems to be stuck at 120!
Forcing it back to 60 in display options, works. Putting it back to adaptive, keeps the screen at 120. Even on the lock screen, and AOD!
I might try a reboot.

If you're in low ambient light, screen at low brightness, panel will be locked at 120Hz even with adaptive selected. Move to bright area or increase screen brightness and check if you are able to get to 60Hz

Nothing odd there - as previous poster mentioned, it's always behaved that way when the ambient lighting is low enough. And yes, has always been that way for AOD too. I never understood why 120Hz is required particularly for that!
I think that after android 12, my unlock animation is rendered at 60hz because it is sometimes sluggish. Did a full factory reset and i have the last update. Do you guys experience the same? other than that the phone is perfectly smooth
Still the same issue with BULC December update. Somewhat disappointing, as you'd think this should be quite an easy fix.
Still same issue after BULG update with PIP. As a previous person has noted, split-screen mode appears to be auto-throttled to 60Hz by default, and the only way to change this so it remains at 120Hz is by toggling "High" or "Maximum" "Processing speed".

Question Refresh Rate stuck at 120hz (battery drain)

Pretty sure, my oneplus 10 pro is stuck at 120hz the whole time which drains A LOT of battery. BUT, isn't this phone meant to be LTPO 2.0 technology which has variable refresh rate as low as 1hz. I am so confused why it doesn't drop to 1hz. CAN SOMEONE PLEASE HELP . I tried those stupid apps like smart hertz and they are useless, shouldn't the phone itself drop to 1hz, like bruh

Hi, in the developper options settings you can toggle on a settings that show you the live framerate of the screen. You will see it drops at 1hz when nothing is happening on the screen. Warning : it drops only to 10hz when brightness is at middle, and stay at 120hz all time at mid brightness
Hope it helps you
Edit : i tried and mine is also stuck at 120hz or 60hz but never dropping below
It was working few months ago
Working fine here
Screen Recorder Doesn't Support 120fps Record
It's stuck on 120hz on my side on lower brightness levels.
On the Standard refresh rate setting, it's altering between 60hz & 30hz on lower brightness levels.
@regrestbuyingOP10pro are you in quad HD + ? If so try to go back at full HD +, then reboot
On my side variable refresh rate worked again after that, but as soon as I go for quad HD it brake it
Still great battery life with quad HD tho
Edit : tried it again and does not worked this time. I really dont know what's causing that, maybe with debloat I disabled an app nedded for that

So i removed root completely, i restored ALL the system apps that i disabled long time ago to debloat the phone, and removed some apps that can changes system settings such as Naptime, 3C toolbox, DarkQ
Rebooted a couple of times and this damn phone is still stuck at 120Hz
I will give up there, except if you have other ideas to test, but i'm too lazy to do a factory reset to see if a ****ter user app is causing this...
Someone have his phone that is dropping fine to 10hz or 1hz with OOS 13 C22, C25 or C26 ?
To know if it is not a system issue of these builds, please tell me
I have never rooted my phone. Refresh rate is working fine for me on C26
