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+, z fold 3, z flip 3). 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.

  • Force 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
    • Galaxy Z Flip 3
    • Galaxy Z Fold 3
  • 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.***
    Note: Currently not working (blocked by samsung) on pre-OneUI4.0 devices updated to OneUI4.*


  • 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 (after ~ 10 secs)***

  • Tasker plugin support: Automate GMH settings with Tasker app. Supported actions/variables: max refresh rate, min refresh rate, keep smooth motion on PSM, motion smoothness mode, quick-doze mod, change dispaly resolution. More info in FAQs below

    Premium Features:

  • Keep High/Adaptive motion smoothness when power saving mode is enabled whether manually or by the system/adaptive power saving***
    Note: Currently not working (blocked by samsung) on pre-OneUI4.0 devices updated to OneUI4.*


  • Adaptive refresh rate mod for devices supporting multiple refresh rates but do not have the stock Adaptive motion smoothness (e.g. S20 series, S20FE, TabS7/S7+) with the ability to set the brightness threshold for its activation***

  • Quick-doze mod: Quickly enter doze mode during screen-off that can not be interrupted by motion ***

  • Set minimum refresh rate for adaptive mode to 60hz or lower (if supported)***

  • Resolution switcher filter: Filter what screen resolutions to include for the resolution switcher QS tile.

  • Auto SENSORS OFF (experimental non-root workaround):
    Device sensors will automatically turn off while screen is off until the device is unlocked. This helps minimize battery-draining motion-triggered wakelocks while device is not being used.

  • Statusbar net speed indicator

  • 7-day Premium Trial is available. Just click "Activate Premium|Trial" button and activate free trial when prompted.

    Note: The premium license is on a per device basis.
***these marked features require a one-time ADB setup (this is not root)

Info: This app targets older android sdk in order to control refresh rates without ADB setup. Just tap OK the dialog that says "This app was built for an older version of Android...." when opened for the first time. If OK button is not visible, just tap the blank space on the lowest portion of the dialog.

I have been trying this mod on my Flip 3 for a few hours, and can already see and feel a big difference.
Battery drain has gone down, and heat generated by the cpu and battery is much improved.
I have set it to Max 96Hz, and minimum 48Hz, and Doze mode ON.

Still a very smooth experience.
Brilliant 👍👍
I have included a couple of screen shots of my settings for those interested?
P.S.
I have executed the ADB command to get full acces to all of the features.

After using this mod for around 20 hours, it has been great. Much improved battery life, and Doze Mode has vastly improved standby drain 👍.
Can't say I miss 120Hz, as 96Hz still gives a great experience.
120Hz is definitely a battery hog, maybe Samsung will improve this with updates.

@tribalfs,
Just testing the app on my new Z Flip 3 (Andoroid 3.1.1 not 3.5).
Not sure if it relates to the new updates... but noticed that the motion smoothness keeps dropping to 96Hz, although it was set to max 120Hz?
Also, noticed that the app force closes a few after installing an update, and then it stabilises...not noticed this behavior on my S20 FE 5G before?

Are you able to identify when this is happening?

Do you have Spay installed? I broke something related to this. Will push immediate fix for this.

App keeps closing after 1-2 seconds here and I can't toggle on the "Force lowest refresh rate on screen-off/AOD".

Latest update available for me, the AUG7 one.

Yes, I found the culprit. I'll post a fix soon.
For the meantime, try performing WRITE_SECURE_SETTING permission using ADB to stop the force closes

Hi! Would you mind sharing the crashlog ?
Pls see below how. Thank you.
If GMH crashes on your device, please send me the crashlog of your device. Just execute the following adb command:
Code:
adb logcat -b crash > crashlog.txt
Ctrl+C after 15seconds.
Then locate crashlog.txt file in your adb installation folder then send it to me. In most cases the culprit can be identified and addressed using this file. Otherwise, I may send a you specially build apk to get the full stacktrace.
 
I wanted to take a minute and say thanks for the app. I came from the Note 20 Ultra and ROG Phone 5, both of which were left to use the automatic settings provided by the firmware.

Moving into this phone with it's tiny kid's edition battery meant having to worry about all the features that weren't active when the screen was on. This app has really delivered on what it claims.

Thanks for taking the time to make something that fixes what the manufacturers always manage to overlook.
