My S24 Ultra's refresh rate constantly bounces between 120Hz and 24 Hz, while in use. Is there any way to disable that? I get the need for a low refresh rate when in AOD mode, but I'd prefer a more stable refresh rate while looking at the phone. I know you can set it to 60Hz, but then it still drops to 24. I am getting noticeably more eye strain looking at this phone than any other phone. Do I have to downgrade to a 24FE?

Or with Goodlock and display assistant app. That's if on ui 7

I was hoping that would do it, but that just set 60 as the max. It still drops down to 24 once you stop scrolling.

Migraines. I can't look at my phone for longer than a few minutes without getting a headache. Never had that issue with the S23U and I can use my work phone fine. The only thing the S24U has that the other phones don't support is refresh rates below 60Hz.

Yay! This will be the answer once I can get one UI 7.

I think you're right about the PWM. I used a fast shutter on my camera to check the PWM flicker and it's terrible when you set the brightness lower. The difference might be that the S24 (and S25) have much brighter screens, so they have to dim them more aggressively using PWM. That's probably why I didn't have the same issue with the S23 and S22... Wish Samsung would enable DC dimming. Guess I'll have to trade in my S24 in for a vacuum or something lol
