[App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods and More)

Search This thread
That's strange.
The app consumption should be what is shown in the device care.
Yeah I never felt like the app was the cause my battery was draining a lot. But I recently changed my battery to a new one, via Samsung assistance center, and the consumption kept being not good. Tried unistalling it and can say it's a little bit better now. Using naptime for doze purpose.
But it could be only a false perception. A placebo, I don't know.
Any updates on the horizon?

Hello there, is there a way to integrate it with Bixby or anything similar so that I could put special conditions to lower the phone into fixed frequency when I enter a app or a special state like 5 seconds screen timeout?

I think there's a bug with auto sensor off. When the option was removed, the phone will still disable sensors but there's now no options to disable it either.

Houston, TX
Samsung Galaxy S21 Ultra
On OneUI5 on my 986U. Been having a problem where high mode is not persistent after going using Sleep mode (under modes & routines...also turns on PSM). Sleep mode is set to turn on automatically at 9:30pm and turn off at 5am. At that point, I would expect the display to revert back to high mode (96hz). However it doesn't work.

Tried using the Keep selected mode on PSM option and that doesn't appear to work as well.

Is this a known issue on OneUI5?

I have some small stuttering especially on unlocking and then scrolling on the homescreen and sometimes while exiting/entering apps. When I remove this app everything is smooth again.

Happens on all resolutions. S20+ Exynos

    About this app:

    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)***
      -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]
      Note: The workaround is already blocked in OneUI5.0. Check the extra steps provided in the app.

    Screen-off Mods:
    • Force to Lowest Hz: Force the lowest refresh rate on screen-off or Always-On Display(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.
      -Tasker plugin support

    • Auto apply power saving mode during screen-off (after ~ 10 secs)***

    • 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.
      -Tasker plug-in support
    • Battery protection mod (Experimental)
      -Option to set maximum charge to 86%-95%(for OneUI4+)[premium]

    • Quick resolution switcher
      -Easily switch to any supported resolutions using the included quick setting tile***
      -Tasker plugin support
      Caution!! Be careful on applying CQHD+ on S20 series with OneUI4.* - it causes the UI to shrink after reboot or long sleep that causes difficulty on entering the lockscreen.

    • 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 .

    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.


    Github wiki (Please read specially before asking questions or reporting bugs)

    v7.14.17 in-app update now available
    -Auto sensors off workaround for OneUI4.0
    -Fixed bug: setting min hz for adaptive (%lhz) usingTasker not working
    -Fixed bug: unable to turn off accessibility when no feature requiring such is enabled
    -experimental workaround for enabling Adaptive/High refresh rate on PSM on OneUI4.0 (may not work on some)
    - other stability fixes
    But I am working on working around this limitation. :)
    Update: After spending some hours of research and tests, I think I now have a workaround to mimic adaptive refresh rate behavior for devices with high refresh rates like S20s. Not 100% perfect but seems working well.
    v6.62.25 now up! :)
    - Fixed crash when opening some apps in Secured Folder
    - Minor improvements on adaptive mod
    v6.62.10 changes:
    - Fixed intermittent bug on restoring power mode settings on screen-on when using quick power-doze mod

    I am getting crashes after latest update. Mostly when I switch between normal apps and apps in secure folder. The app has stopped and it closes.
    Now that I did the thing with the adb I have the same problem. Small screen flash when the rate changes.
    Yes, because you are in adaptive mode now. Adaptive is working but not the high mode. I will push an update to fix this soon.
