No 10hz on the S21 Ultra - Page 2

adamlee · ‎25-02-2021

Samsung stated that when not touching the display it will be 10hz. Lowest mine goes is 48hz.

There was a widget on XDA for the S20 series to switch to 96hz from the notification panel. I imagine they may be able to make one for the S21 Ultra although the screen refresh is handled very differently.

has anyone heard more about this topic? I put on developer options and checked my refresh rate, and I cannot get it to go down to 10hz. Best I get is 48 on certain youtube videos. Usually 120hz or 60hz while static screens...

Apparently the built in Refresh rate in developers menu only reads 48hz 60hz 96hz and 120hz. The phone could go to 10hz when viewing a picture but the overlay will show 60hz

Thanks for the info Adam. And that's quite possible, but so then is there a way to confirm this, ie a program that either records or displays the refresh rate while not affecting it?

Thanks!

Same for me, I couldn't get it below 48Hz and I have an S21 Ultra as well. I managed to dig up this ADB command to change the screen refresh to 96Hz on the S20 Ultra, and modified it to get 10Hz:

adb shell
settings put system min_refresh_rate 10
settings put system peak_refresh_rate 120

Sadly, no dice, still defaults to 60Hz. Even I set both min_refresh_rate and peak_refresh_rate to 10Hz, it just goes to always running at 60Hz like it's ignoring me completely. But, if I set both to 48Hz... Now I can get 48Hz everywhere! Of course this is way too choppy when scrolling, so it would be nice if I could at least get 120Hz then drop to 48Hz for videos/etc, but if I don't set BOTH to 48Hz to force it, it just jumps back up to 60.

And fun fact: Most YouTube videos are 30fps, not 60. So screen running at 60fps seems like a bit of a waste since most of what I do on the phone is watch YT videos or browse websites. The latter of which I wouldn't mind doing at 10Hz when not scrolling. But that doesn't seem to be possible.
