Imagine the battery life in standby if the display was set to 10hz. It would be amazing but yeah got to wait for Samsung to enable it. Can't understand why it's not already available. They definitely mentioned it could go as low as 10hZ
[App]Galaxy Max Hz (Refresh Rate Control, Quick Resolution Switcher, Screen-Off Mods, Adaptive Mod, Keep High/Adaptive on Power Saving Mode and More)
- Thread starter tribalfs
- Start date
If you turn down the brightness to lowest and flick between refresh rates... You'll see 48hz and 96hz have a green tint. Noticed on my s21 ultra.
They Mentioned 10hz when not touching the display. Hopefully the next software update enables it.

Screenshot_20210225-234929.jpg
On s20 U SM-G988B whenever I click on adaptive it goes to standard. Tried clearing cache/data, uninstalling and reinstalling to latest apk. Followed the instructions for adb but still doesn't work.
Not possible without the latest panel installed on S21 Ultra (only). The rest (S20, Note 20, S21 series) supports 48hz as lowest refresh rate. Not something that a software update can do
Try to clear app data after performing the adb instructions.
Hello. Version 6.61.10 works stably. Thanks for fixing the bug so quickly.
Okay somehow its working now. Thanks for the ongoing updates to the app.
I thought it was just me and a battery optimisation issue but I turned on the notification refreshrate to keep the app alive and it helped.
I already restarted my device, uninstalled the app, cleared data and ran the adb command several times but the app keeps crashing whenever I switch from QHD-60HZ to something else.
It allows me to go from FHD-120 TO QHD-60 but it won't switch back.
I'm on the latest update.

Can you share screenshot with the app opened? Are you using the app's resolution changer?
I can confirm this is happening right after unlocking the phone using fp before touching the screen again. Only resumes to 48hz once touch. Is this your case?
Thank you. Refresh rate profiles looks alright. Is this happening also on adaptive mode? Can you share another screenshot with adaptive on?
This is what happens, it won't even show the options to switch to any other resolution.
And the dedicated button just crashes the app when pressed.
Th
This is strange. Only one resolution for standard. Can you perform clear app data now? Don't uninstall - need to keep the adb permission.

v6.64.20 is now available.
- Fixed bug on refresh rate not being fixed on games when the in-app refresh rate monitor overlay is turned-on 5Thanks for the workaround, as my power saving mode mainly automated by Tasker or Bixby routines (seldom turn it on manually)
v7.00.20 in-app update now available!
5Update: Currently pausing this update due to adaptive mod issues on some S20 devices.
v7.00 is now up!
- `Keep motion smoothness on power saving mode` will now take effect immediately after toggle - Filter what resolutions to include in the screen resolution switcher - Power saving mode and deep-doze are now separate options under screen-off mods - Additional deep-doze option with no maintenance window added - Adaptive or high motion smoothness on CQHD resolution now sticks after reboot. 5v7.00.10_beta2 is up!
Includes fix for crashes of some devices and some adjustments on doze modes to prevent it from being interrupted by constant motion. This should improve doze performance when the device is constantly in pocket or in motion.

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 the app's Tasker plugin support. Supported actions/variables: Max Refresh Rate, Keep Motion Smoothness on PSM, Motion Smoothness Mode, Quick-doze Mod, Change Screen Resolution. (new in v7.10). More info in FAQs below.
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+)***
- 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.
Info: This app targets older android sdk in order to control refresh rates without ADB setup. Just ignore the dialog that says "This app was built for an older version of Android...." when opened for the first time.

Hello everyone.
v6.61.10 build is now up - should fix bug on refresh rate profiles not properly loading introduced in v6.61.0*.
v6.61.10
- Fixed bug on refresh rate profiles not properly loading(bug inroduced in v6.61) Clearing app data is highly recommended after this update
Thanks to all who reported the bug.6FAQs:
- I am on adaptive or high refresh rate mode, but why my refresh rate stays at 60hz on google maps, waze and some other apps and games even if I set a higher max refresh rate?
These apps are either (1) blacklisted by the android system to not use the high refresh rates due to compatibility reasons, (2) sets its own preferred refresh rate or (2) controlled by Samsung's game optimizing service (game launcher). GMH app can't force these apps to use high refresh rates.
- How does Quick-Doze Mod work?
If enabled, the device will quickly enter into doze mode (except when charging) during screen-OFF. This will make a better standby power consumption. This works best with "Power Saving Mode on Screen-off" enabled. Doze mode will stay until the device is unlocked. Motion detection will not interrupt this doze mod. The general behavior of doze mode is described below:
Some app notifications are only allowed during the maintenance window except for SMS, those apps using High Priority FCM and those which battery optimizations are disabled. If you want certain apps to ignore this behavior, just disable battery optimization in their respective app settings.- Why I don't have 48hz and/or 96hz on my device?
Currently only the following Samsung devices have 48Hz and/or 96hz enabled:- Note 20 Ultra (48 & 96)
- S21 Series (48 & 96)
- S20 series excluding FE (48 & 96 - but 48hz was removed by Samsung in OneUI3.1 update)
- In Adaptive refresh rate mod, I set minimum refresh rate to 48Hz but while watching videos, refresh rate only goes down to 60Hz
On video apps like youtube, the default refresh rate is set to 60Hz but it will automatically go down to 48Hz on compatible videos (i.e 24fps or 48fps videos). Most videos in youtube are in 60fps format.
- Adaptive mod does not go down on GAMES and also when notification panel is expanded.
On games, the refresh rate will adapt to the highest refresh rate the game supports and will be fixed on that refresh rate. This is to preserve input responsiveness and smoothness while playing. If the game is not compatible to the currently set max Hz, it will use the next lower compatible refresh rate. On expanded notification panel, it does not go down when you enabled the app's refresh rate monitor and/or net speed indicator - this is to avoid refresh rates constantly jumping up and down when refresh rate and/or net speed values are updated. However, if both are disabled, refresh rate should go down like the usual adaptive behavior.
- Is the Adaptive refresh rate mod in the app the same as Samsung's native adaptive refresh rate. Is it based purely on touch input?
For those devices that do not have the Samsung's native Adaptive refresh rate mode, the app's own Adaptive Mod is applied. But for those devices that have the native adaptive refresh rate, the native adaptive refresh rate is applied 'as is', except when you override the minimum refresh to lower than 60Hz .
Aside from touch input, the app's Adaptive mod also considers the changes on the contents being displayed on screen like the native implementation. It is a goal of this app to make the Adaptive mod behavior similar to the native one.
For those devices not natively supporting adaptive refresh rate, some users experienced flickers when refresh rate switches more specifically under low brightness and specially when using 96hz and/or 48hz. This is an issue of consistency of gamma curves across the different refresh rates. Samsung possibly did less calibration on 96hz/48hz. This also has to do on the hardware tech that is used in the display (LTPS).
- Can I add the CQHD+(custom QHD) resolution that supports 96hz/120hz for Note20Ultra or S20 series device?
Yes, this option is added as requested by some users. Connect to the internet before opening the app for the first time -or - clear the app's data and open it while connected to the internet in order to load the profiles from my server containing such resolution. The server copies of the resolution and refresh profiles have the following additional resolution:- Note 20 Ultra: 3087x1439 @ 48/60/96/120 hz
- S20/S20+/S20Ultra: 3180x1431 @ 60/96/120 hz
- How to activate ad-free trial?
Click the 'Activate Ad-free' button and click 'More Info' into prompt that will appear. Type in "TRIAL" and apply. You will have 7-days to test the ad-free extra features.
Starting with v7.**.**, activate ad-free trial will automatically prompt when it is still available to your device. Just click ok.
- Why is it that we can't download this app in play store and how do we know it's safe?
This app targets older android sdk in order to set refresh rates without ADB or root requirement. Unfortunately, play store doesn't anymore allow us to publish app targeting such older sdk. If you doubt if it's safe, you can scan it with any virus scanner like virustotal, metadefender, with Samsung's built-in threat scanner powered by McAfee or Google Play Protect scanner.
- I constantly receive sound/vibration alerts everytime real-time refresh and/or netspeed indicator is turned-on. How can I turn it off?
In case you're experiencing this, you can turn this off in the app's notification settings (long press app icon > app info > notifications > open each notif category and set to silent). This is fixed since v6.62.
- How to setup GMH with Tasker?
Create(+) a Task in Tasker app and give it a name. Inside the Edit Task window, add GMH action by clicking (+) button > Plugin > Galaxy Max Hz. Click the (edit) Configuration section to see the tasker settings/variables available for GMH. Set a value to each of the variable that you want to apply by clicking (+) button > Variables >Variable Set > enter the variable name and a corresponding valid value. Ensure to put Galaxy Max Hz action task after all the Variable Set tasks (use hold and drag to re-order).
You can then link this Task to the Profile/Trigger that you want to use. You can create multiple GMH tasks with different variables.
If you want to override behavior for certain apps, just create an Activity trigger and another Activity Invert trigger for this/these App(s) in tasker profile, then create each corresponding GMH task following the above steps and link them to the respective profile.

Questions and Bug Reports:
Feel free to ask questions relevant to this app here should your question is not addressed in FAQs above.
For suspected bugs, you can send me a direct message or post it here. Read the FAQs also to check if it is an intended/expected behavior or not. Also check if the latest version is already installed in your device. Please include your device model number, OS version, app version and the steps to reproduce the bug. If possible, attach screen recording* or screenshots. This can be very helpful to me in answering your question or in reproducing and resolving the bug faster.
*You can use this screen recording app capable of recording high refresh rates
Due to the app usage of non-sdk and non-public api to execute most of its features, it is not guaranteed that all of its features are going to work in the future android iterations, should the new iteration block/disable them. But the dev will do his best to keep it working as long as possible.
Sharing Outside XDA:
Feel free to share this app anywhere as long as proper credits and reference to this thread are provided. Do not create any alternative download link. This is to ensure that users get the untampered installation file, latest information and latest updates of this app.
Unresolved Bugs:
- Samsung Pay is reported to be crashing when using this app. Currently investigating on this. I am encouraging anyone who is experiencing this to also send/report the Samsung pay crash log to Samsung.
Update: Based on my research, it seems that this is happening when using any app that uses a screen overlay.
