About this ap:


Refresh Rate Mods

  • Change default refresh rates
    -Easily change the overall refresh rate settings of devices supporting multiple refresh rates.
    -Set supported mid refresh rates as the maximum refresh rate limit for battery savings (e.g. 96hz instead of 120Hz).
    -Quick settings shortcut
    -Tasker plugin support

  • Motion smoothness mode switcher(Normal, Adaptive or High)***
    -Set you device motion smoothness mode to stationary refresh rates (high mode) for better smoothness if so desired on Samsung devices with native Adaptive motion smoothness with a little trade-off to the battery.
    -Apply adaptive mod on device that don't natively support adaptive mode [premium]
    -Tasker plugin support

  • Per-app refresh rate settings:
    Set different refresh rate settings for every app either adaptive or fixed(stationary) [premium].

  • Motion smoothness on power saving mode (not working to all devices with OneUI4.**+, test first). ***
    -GMH will apply a workaround to bypass 60Hz limitation on Power Saving Mode (PSM) on supported Samsung smartphones.
    -Automatically apply workaround when PSM is enabled [premium]

Screen-off Mods:
  • Force to Lowest Hz
    -Force the lowest refresh rate on screen-off or Always-On Display(AOD) to improve standby power consumption a bit.

    -Select refresh rate to set for AOD/screen-off[premium]
    -Tasker plugin support.

  • Auto apply power saving mode during screen-off ***


  • Auto disable Autosync***


  • Quick-doze mod
    -
    Quickly enter doze mode during screen-off that can not be interrupted by motion [premium]***
    -Tasker plugin support


  • Auto SENSORS OFF (experimental non-root workaround)
    -Device sensors will automatically turn off while screen is off until the device is unlocked to help minimize battery-draining motion-triggered wakelocks while device is not being used [premium]
    -Tasker plug-in support
    - Supports up to OneUI4.* only
Others
  • Battery protection mod (Experimental)
    -Option to set maximum charge to 86%-95%(for OneUI4+)[premium]

  • Customizable refresh rate monitor
    -
    Use statusbar or overlay which you can place anywhere on screen.
    -Tasker plugin support


  • Net speed statusbar indicator
OneUI inspired UI. Dynamic theme and Icon. Manual language selection

Note: The premium license is on a per device basis (not per user).


***these marked features require a one-time ADB procedure (this is not root)

Galaxy Max Hz background service is highly optimized. Background battery usage p is very negligible .

Info:
This app targets older android sdk in order to control refresh rates without ADB setup or root. 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.

If google play protect will prompt during install that the app is built for older version of android and doesn't include the latest privacy protections, you can ignore it and proceed to the installation. For privacy related concern, please refer to FAQ No. 3.

It looks totally different on my fold 4? It's like stuck on adaptive but seems to be letting me set per app rate.
Does the screen off 10 work with aod?

We don't have the Z Fold4 to test yet but it should be since Z Fold4 is capable of 10Hz.
I more less was thinking if the aod holds the screen on 24/7 if the 10hz lock still happens?
Looking to save battery if I can loli need aod on due to media controls with the phone "off"
Either way thanks 🖤🤗

the problem with 10Hz is that all apps (instagram, reddit etc) that shows videos are stuttering, so I need to use 24-120hz on those apps.
Yes, that's a known limitation of GMH when setting min hz to 10Hz (for these apps which are restored from backup or not installed directly from play store).

For device like ZFold4, It's recommended to keep default min refresh rate to 24Hz and just use the per app settings to adjust individual app refresh rate settings to your liking..

Hey, thank you very much for this amazing app! 😄

Two Issues:
  1. I can just choose between "standard" and "adaptive" mode. The "high" option is greyed out. Why is that, and how can I use high mode?
  2. I can't use the Tasker plugin. I can just add the plugin, but the edit button doesn't show the configurations. Am I doing this wrong?

Questions:
  • Can you add a QS tile/toggle for "PSM when screen is off"?
  • the option to limit the refresh rate while tying is just 60Hz, why can't this be lower like 10-24Hz?
  • At the top of the app it shows the device and says the model, Android 12, but it says "OneUi4.5", but it's on "OneUi4.1.1."
Thank you very much for your help 😁

What version of the app you installed?
And what is the exact model number of your device?

Thank you.

That OneUI4.5 version is a bit strange. That value is actually read from a field in OneUI's Build class.

  • It says: Version 8.0.0, I set it to alpha update channel. It doesn't say "beta" like in your screenshot here
  • In settings app, it says: SM-F936B/DS
  • I don't understand the One UI version either
  • I bought premium, and it also says that it's activated
------------------------
EDIT: I cleared cache & data and installed the most recent version from GitHub. Now the "high" mode is available again.

I've set up Adaptive to 24-96Hz. Now I have a weird bug, that locks the front screen to 24-60Hz and on the main screen it's correct 24-96Hz. No PSW or anything.

I don't know how to use the Tasker plugin. When I open it, then it just shows a long block of text, (see attached screenshot). There's an edit button (pencil icon) at the top right, but pressing it does nothing. Is there any configurator or even an (G)UI? Or how am I supposed to use the plugin?

Thank you very much 🥺

Hi there. Despite changing the update channel to beta, I cannot get the beta version of the app. Tried clearing cache and data several times but still no success. Any idea? I also bought a license. Thought that was the issue but still no update to beta. Helps please? Really wan to use high refresh in PSM. THANKS.

Just reporting that the per-app settings master toggle seems to be ignored. I set my device globally from 10 Hz to 120 Hz and found that YouTube would fall down to 10 Hz when playing videos rather than 24 Hz (which also shouldn't happen). I rectified that by setting YouTube alone to 24 Hz - 120 Hz, but forgot to activate the master toggle for per-app settings. When I switched to YouTube however, it was now working correctly. It wasn't until later that I discovered that I never changed that setting, and testing with it both enabled and disabled seem to have no impact on the behavior. Only completely resetting the individual setting for the YouTube app restored the original (buggy) behavior.

Great!

Seems Samsung set higher brightness threshold for 96hz on the front screen which disables 96hz on low brightness condition. Unfortunately, this is beyond control of GMH or any third party app.

I don't know how to use the Tasker plugin. When I open it, then it just shows a long block of text, (see attached screenshot). There's an edit button (pencil icon) at the top right, but pressing it does nothing. Is there any configurator or even an (G)UI? Or how am I supposed to use the plugin?

Please check #16 in FAQs.

Thank you.

I believe that the installed youtube app was restored from backup and then subsequently updated from play store.
This is related to the limitation I mentioned here. Thank you.

I understand that youtube not correctly applying 24 Hz falls under the limitation you mentioned, however shouldn't setting the per-app profile for youtube to 24 Hz minimum, but not having the master per-app toggle on not alter youtube's behavior at all from the global behavior set?

No, global behavior for apps detected as video player is 24hz min unless higher min hz is set as default.

I get that, but with the GLOBAL setting set to 10-120, and the master per-app toggle OFF--meaning NO settings within per-app settings should affect behavior--YouTube falls down to 10 Hz during playback when the YouTube per-app setting is left cleared, but correctly plays back at 24 Hz when its per-app setting is set to a minimum of 24 Hz. Why is YouTube's per-app setting having an affect on refresh rate within the YouTube app when the master per-app toggle is set to off?

    96Hz only works on certain (higher) brightness levels on ZFold4 to reduce visible color shifts and/or brightness flickers which our eyes are more sensitive on darker environments. That threshold is set by the manufacturer depending on the display calibration. Unfortunately, it is not something an app can override/modify.

    I am a loyal user from z fold 3 to Z fold 4 who benefit much by using Galaxy Max hz. Can developer please fix the issue of lagging in using camera preview. I tried to use at a fixed 60 hz in camera app but it is still laggy
