SwitchHZ : App which let you control refresh rate.

About this app:
Refresh Rate Control: Easily control the max refresh rate (Hz) of android devices with multiple refresh rates (e.g. note20 ultra, s20/S20+/S20Ultra, z fold 2, s21/s21+/s21Ultra, tab S7/S7+). This app can limit max refresh rate to 96hz (or any available refresh rate) on supported smartphones - you can save power with negligible difference on smoothness. Use either the in-app toggle or quick settings tile - ADB setup or Root NOT needed.
Switch to High: Option to use High(Fixed) motion smoothness mode on Samsung devices with native Adaptive motion smoothness***
Current Samsung smartphones natively supporting adaptive refresh rates:
Galaxy Note 20 Ultra
Galaxy Z Fold 2
Galaxy S21, S21+, S21 Ultra
Refresh Rate Monitor: Observe how multiple refresh rates work on your device. Use either the in-app toggle or quick settings tile
Quick Resolution Switcher: Easily switch to any supported resolutions using the included quick setting tile***
Quick High/Adaptive on Power Saving Mode: Easily switch to high or adaptive motion smoothness mode (from Standard) even on power saving mode on supported Samsung smartphones.***
Force to Lowest Hz: Force lowest refresh rate on screen-off/AOD. This overrides Samsung's strange stock behavior which sets the refresh rate to the highest on screen off (update: it is now at 60hz since oneui3.0) - to improve standby power consumption a bit - ADB setup or Root NOT needed.
Auto apply power saving mode during screen-off***
Tasker plugin support: Automate GMH settings using Tasker plugin support. Supported actions/variables: Max Refresh Rate, Keep Motion Smoothness on PSM, Motion Smoothness Mode, Quick-doze Mod, Change Screen Resolution.
Ad-Free Exclusive Features:
Keep motion smoothness when power saving mode is enabled - either manually or by the system/adaptive power saving***
Adaptive refresh rate mod: Experimental adaptive refresh rate mod for devices supporting multiple refresh rates but do not have the native Adaptive motion smoothness (e.g. S20 series, S20FE, TabS7/S7+, A52, A72)***
Quick-doze mod: Quick doze mode during screen-off to improve standby power consumption***
Set minimum refresh rate for adaptive mode to 60hz or lower (if available)***
Resolution switcher filter: Filter what screen resolutions to include for the resolution switcher QS tile.
Statusbar net speed indicator
7-day Ad-Free Trial is available. Just click "Activate Ad-free" button and activate free trial when prompted.
***these marked features require one-time ADB setup (this is not root)

Isn't it possible to get the screen damaged/worn out, when its switching the refresh basically every couple of seconds?

I don't think so as long as it's switching only between supported refresh rates.
v7.12 in-app update now available
- More customizable maintenance window interval for Quick-Doze Mode
v7.11
- Added turn-off autosync option under screen-off mods
v7.14.00 in-app update now available.

v7.14
Added Auto SENSORS OFF (experimental non-root workaround): Device sensors will automatically turn off while screen is off until the device is unlocked. With tasker support so you can enable and disable this setting on the conditions you set.

v7.13
Anti-flicker: added minimum brightness threshold for Adaptive mod similar to the native one. When the device's display brightness falls below the set minimum brightness threshold, adaptive mod will pause and will resume once the brightness increases again above the threshold. This is for devices who are experiencing flickers when refresh rate switches at certain low brightness level.Stability and bug fixes

Thanks for your work, gonna test with my A72 as soon as it arrives
v7.14.18 in app update
Fixed bugs on OneUi4.0: brightness threshold for adaptive mod bug, netspeed indicator bug
Fixed bug on minimum hz tile and minimum hz tile tasker command
Minor layout and tile improvements
Auto dim refresh rate overlay when not changing after few seconds
Fixed crashes on netspeed indicator
v7.14.17
Workaround for auto sensors off for OneUI4.0. Prior method was already blocked in A12.
Experimental workaround: enabling High/Adaptive on PSM on OneUI4.0 (not working on some models)
Fixed: setting min hertz for adaptive (%lhz) using Tasker not working
Hello, can we downscale refresh rate to 90hz to save battery? I dont notice 90 120 diff anyway haha

Summary
Pixel 6 Pro goes down to 10 Hz as expected when idle in normal lighting
In low ambient light & low brightness for darker content, refresh rate only goes down to 60 Hz
Pixel 6 Pro PWM frequency is 360 Hz, lowering down to 120 Hz at <20% system brightness
AOD goes down to 10 Hz as expected
Battery Saver/Smooth Display disabled does not go down to 10 Hz, stays at 60 Hz
Watching 24fps/30fps movies/videos does not lower refresh rate down to 24/30 Hz, stays at 60 Hz
The important bits
Some people have (mistakenly) used Android's refresh rate indicator within the Developer Options to come to the conclusion that the 6 Pro's variable refresh rate only goes down to 60 Hz, because that's what the indicator shows when the screen is idle. However, Android's refresh rate indicator does not show the OLED panel's lowest operating refresh rate, due in part by how its VRR is implemented. The Pixel 6 Pro's Samsung Display panel has a variable refresh rate mechanism that operates at a much lower level, within the display driver, and not exposed to the Android user-space.

Samsung's VRR implementation is not the same as those found in typical gaming monitors which can target any arbitrary refresh rate. The VRR found in Samsung's HOP ("LTPO") panels still work by switching between discrete refresh rate modes, like older implementations, but the new panels now incorporate a low frequency drive (LFD) mechanism which operates the OLED driving rate at a fraction of the current refresh rate mode. As an example, a 10 Hz driving refresh rate is achievable by operating the panel at 60 Hz but skipping re-drives for 5 out of every 6 refresh intervals if the frames are the same.

And from (#1), we finally find some solid proof that there is a 10 Hz fundamental driving frequency in the Pixel 6 Pro display when screen content is idle, despite the Android refresh rate indicator reporting 60 Hz.
Along with it, we find two other fundamental frequencies at 120 Hz and 360 Hz. The peak at 360 Hz is almost certainly the PWM frequency, and 120 Hz is the fundamental refresh frequency from which the 10 Hz LFD is employed from.

I also tested if the Always-On Display went down to 10 Hz (#5), and I can confirm that it does. It's driven at a 120 Hz PWM freq. and a 60 Hz fundamental refresh, employing LFD down to 10 Hz.

How to force to use 90hz instead of 120hz?
you can chose auto-select to automatically select the best refresh rate for an app
otherwise you cant chose then 60 or 120
