How To Guide Force 120Hz Guide (S22)

[MochaVex]

[Tested. Works as of One UI 4.1 September, 2022 Patch AVHH Build]

Hello again! A handful of you may have seen my S21 guide for forcing 120Hz through pretty much every app and while the camera is active (looking at you, Snapchat!!). The previous guide doesn't apply to the S22 series because Samsung changed the range of valid refresh rate values all the way down to 1Hz.. WELL I still managed to break it... 0.1Hz as a value apparently works.

A kind user made a video based on my guide: Linked;

I also want to say that the August update seems to have broken something for some users, but I've re-applied this on said update and it still works fine on my end.

This is also for allowing 120Hz when the camera is active; not so much forcing 120Hz (some users got confused because of my poor choice of wording).

Before you start, make sure your refresh rate is set to Adaptive.

1. Download SetEdit from the google play store.
2. Open up to the system table.
3. At the very top, you'll see an option to add a new setting. Go ahead and tap.
4. enter this: min_refresh_rate
5. Save changes. For the second value, enter: 0.1
6. Do this again but instead start with: peak_refresh_rate
7. Save changes
8. enter again, : 0.1
9. Save changes.

That's it! You'll still benefit from adaptive refresh rates when the screen is still and most apps will run in 120Hz regardless of their manifest. Enjoy a smooth Snapchat and everything else!

No.. Google Maps still runs at 60Hz; but rightfully so! It uses a lot of battery as-is.

If you want to undo this, carefully delete the lines we added and reboot the phone.

Will this force games like COD Mobile to run in 120pfs?

It won't 'force' games to run any higher than they are programmed to. It just allows the screen to go up to 120Hz in most applications that normally wouldn't.

Thanks, makes sense.

What FPS counter app do you use?

Thank you for this! Does this tweak have an impact on battery life?

if you want play COD with 120hz just use [App]Galaxy Max Hz ,
i play on mine s22 with very high graphic quality and force 120hz with this app

Nothing too noticeable in my experience between stock and forced.

That's still not 120FPS though, alls it is doing os putting out 120Hz.

Thank you for good article.
Is there any way to fix 90 or 96Hz not 120Hz?

Doesn't work anymore on August update

For my Tab 8, on newest firmware I had to change the min_refresh_rate value to 120. Leaving the peak_refresh_rate at 0.1 Instantly locked to 120.

Actually tested this on my s22+ and the result was me having "grey" screen instead of black in 24hz, just deleted the "peak" and "min" values and restarted and was solved! If anyone getting this, that is the solution.

does it work on s22 ultra in agust 2022 update?

Re-applied just now and it seems to without any issues.

Any way to use system table or other means to allow adaptive refresh when battery saver is enabled? Even if peak is still 60 fps with battery saver on, seems like it would still improve battery life to have it drop down to 24 or whatever it normally does when there is no motion, though I may be completely wrong.

Why can't Samsung give what we want in the first place? Why don't we have the freedom of choosing what refresh rate our phones runs on, like for ffs

Not that I could find.. They fixed system table modifications for what you're asking for with One UI 4.0's release. Galaxy Max Hz App *might* be able to accomplish this but I'm not entirely sure.

The Beta Moderator's reasoning was that the phone's hardware couldn't handle the screen running up to 120Hz in every single activity.. part of that is proven incorrect and the rest I can't vouch for because no matter what I do some apps just refuse to go higher than 60Hz.
