Hello,
Recently got this phone and very happy with it. Only issue I have found is that the screen occasionally dims randomly, not by a lot, but noticeable when it happens.
Adaptive brightness is off. System mode is set to dynamic.
Is dynamic system mode the issue? If so which is a good adaptive battery setting which won't affect the screen brightness.
Thanks in advance
I assume its due to the changes in refresh rate. Try setting the refresh rate to a single value (120 90 or 60) and i think you wont see the transition.
Same issue and I have adaptive brightness on. You will open an app and suddenly brightness will turn all the way down. Definitely a bug.

Thanks for the suggestion. I've tried this at 90hz, for reasonable battery, but it still does it.
Same here! Locked at 90hz, so that's not the problem.
I'm having the same issue. Adaptive brightness off, fixed refresh rate. I've only noticed it when I'm outside in bright light.
same problem.
have zenfone 7 rooted. locked to 90hz. adaptive brightness switched off.
anyone found a solution or cause?
I've noticed it happens when i tilt the phone.
and also when i have an app overlaid over main screen. like YouTube vanced minimised etc.
i think phone somehow might be switching brightness between the small app at the front and the main app on the back and doing it back and forth.
Once the screen changes to 60hz and if you then where to rotate the screen without touching it, it will remain at 60hz during the rotation and look slightly laggy.
Exynos / OneUI 4.0
Proof: Laggy Stuff
TLDR: The screen should change to 120hz during the rotation.
Samsung, plz fix.
Welcome to XDA
Lol, slow screen rotation is a Samsung trademark
It's not a 60hz thing per se. May have to do will the sensor refresh rate at least on fixed display rate devices.

No it is a 60hz thing, the screen does not boost to 120hz when a rotation is happening. You can check this by using a system FPS overlay.
Mine changes to 120 on screen rotation. It is very very brief but it definitely happens...

I'm facing the same problem, maybe reducing the refresh rate helps it?
I just tried to replicate the issue on my phone as follows:
Opened a web page and when i was scrolling around, refresh rate was 120.
Stopped scrolling and refresh rate dropped to 60.
Without touching the screen, I rotated the phone and refresh rate goes up for a split second to 120, then as soon as rotation is complete, it dropped back to 60, untill I touched the screen again.
Tried this multiple times, and it's a reproducible behaviour.
I think it's working as intended. As the screen rotates, refresh rate ramps up to 120, making the rotation animation smooth, then it drops back down again to its previous state. I wasn't able to produce any lag during the screen rotation in my tests. It's very smooth.
I tried screen recording this behaviour but turning on screen recorder locks the screen to 60Hz and can't see the changes in refresh rate. One would need to record the screen with another camera/device to show the behavious I've described above.

Do you have Exynos or QC?
Doing the same thing I can reproduce not boosting to 120hz during rotation, I can post video as proof.
Video added in original post.

Exynos.
Did the test on BUK8.
Just upgraded to BUKG.

Well that doesn't make any sense, can you post a video?

Bought Pixel 5 form Aliexpress a month ago and now I'm facing a green tint issue. On low brightness and dark colors (especially gray shades) the screen becomes green. Moreover, while switching refresh rate from 60Hz to 90hz the screen is bliking. Sometimes this thing pisses me off.
I've been searching the whole week and found some people solved this by switching to popular custom kernel. But I couldn't find what kernel exactly.
Maybe someone out here know what kernel to choose (or maybe there is another way to solve this?) A new display cost half the price of the phone, which is not the solution I want (
I have a similar problem. My P5 has a uniform green tint, regardless of the brightness. I recommend flashing any kernel with RGB control and lowering the green channel until you are satisfied.
As for the blinking problem when switching refresh rate, I suggest enabling Developer Options and toggling "Force peak refresh rate". That way your phone will stay at 90Hz.
Sometimes even if I disable de "smooth screen" option in screen settings, the screen refresh rate keeps at 90hz. No matter what I do, what app I open.
I have developer options disabled.
The only way of forcing the 60hz is by enabling the battery saver mode...
Do anyone has faced this issue? Sometimes restart the device fixed it and sometimes not.
I turn on show screen refresh rate in Developer mode.
Then it only show 120 hz in almost state, almost app, while am not touch it, and in stactic display.
Only drop to 60hz in game or full screen youtube.
Never down to 1hz.
How to fix that ?
