hello and thank you for developing this awesome app. I just have a few concerns.

i initially used this app on my s23 and i got sot of like 4-5 hrs 85-1%. I did a factory reset and haven't set up the app yet and now i get 7 hrs with the same battery range.

i got premium, did adb and all. i use per app settings, keep adaptive on psm, quick doze, and 10hz aod.

am i doing something wrong or is it like a development limitation? i hope to be able to support this app again. :) thank you!

  • 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: Stopped working out-of-the-box on Note 20 Ultra updated to OneUI4.*. Extra steps alread required:Extra steps to bypass restriction on OneUI4.*/5.*. After selecting Adaptive or High in GMH while on power saving mode, do either: - Do a quick fake/mock video call to any number using the stock video call app(not google duo). Availability depends on network support
OR
- Connect and disconnect to a wifi display or miracast receiver (e.g. smart tv, chromecast, windows laptops) using the Smart View function (Credits to @albiGib and @rblckmnjr84 for sharing the discovery)
OR see Game booster method
The extra steps needs to be done everytime PSM is switched on and on every reboot

It's permanent but it is only for one phone. If you want it on another device you need to pay for it again. I didn't have that problem, but I guess you need to set the aod to 60hz.

I just bought the app, one question.
What does the "Keep selected mode on PSM" switch do? Please elaborate.

Edit:
Found the explanation on github.

Hi, love your app. I've bought for my N20U and recently switched to A54. Would you be supporting the Samsung A54 in the future?

Hi. I have a S23 Ultra. Got the Premium app today. I want to report that if I set the max refresh rate to 96hz, it will sometimes be stuck in 60hz when brightness is on the lower side of the bar. If I start to slowly increase the brightness it will finally go to 96hz. This doesn't happen when the max refresh rate is 120hz.

This happens without any other mods ot setting being applied.


Im running One UI 5.1 and the app version is 8.1.10

Hi.I have a s23 Ultra me too. I think I also have encountered your problem. Setting 96hz but sometimes the screen will be stuck in 60hz

Some more info related to the issue I reported earlier. If I'm in a well lit environment and manually decrease the brightness, it will actually go to 96hz.

If I then cover the light sensor with my hand, it is at that point where the screen will be stuck at 60hz.

So it seems that this issue triggers only when both the brightness is low and light sensor doesn't get much light.

I can continuously see how it goes between 60 and 96hz by covering and uncovering the light sensor, while the brightness is at the lowest.

Hope these details help to fix this issue.

    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)***
      -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]
    Need extra steps on Note20U starting OneUI4.* except when rooted with magisk and using lsposed(experimental). Test it first
    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

      - Supports up to OneUI4.1 only (api blocked in OneUI5)

    Others
    • 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 Note20Ultra 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 .[/TD]


    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.

    Previous changelogs (old app)

    v5.40
    - Fixed landscape orientation layout bug and other layout improvements
    - Added support for Note 20 Ultra Non-5G models (all features)

    v5.26
    - Fixed disabled "High/Fixed Motion Smoothness Mode" switcher on Galaxy Z Fold 2. You should be able to use this function now in Z Fold 2.
    - Fixed force close bug on Galaxy Z Fold 2
    -Fixed missing resolution label for Galaxy S20 series
    - Other code clean up

    v5.20
    - Qs tiles for refresh rate control and resolution switcher now have dynamic icons. Better visibility for partially expanded notification panel.
    - Added high/fixed refresh rate mode/option for Galaxy Note20 Ultra and Z Fold2. If enabled, the device will be set to 'High Motion Smoothness' mode and refresh rates will behave like the Galaxy S20 series.

    v5.00
    - Added support for Galaxy S20, S20+, S20 Ultra and S20FE. Resolution switcher is not applicable to S20 FE.
    - Renamed app to Galaxy Max Hz

    v4.00
    -Added 'Resolution - Motion Smoothness Mode' switcher (button and qs tile). Switch resolution and motion smoothness mode anytime even on medium power saving mode. This specific function requires ADB.

    v3.00
    - Changed overlay display FPS to screen refresh rate (Hz)
    - Refresh rate monitor now switches color to red if 60hz or below and to green if above 60hz
    - Added toggle switch for refresh rate monitor on app's home screen

    v2.00
    - The 3-way toggle button and quick settings (qs) tile are now aware if the current Motion Smoothness mode is set to Adaptive or not. If not, they will show 'Standard' and will open the display settings when clicked
    - The switch for the FPS monitor overlay is moved to a new qs tile. You can now turn the FPS monitor ON/OFF anywhere without opening the app.
    - Changed text color of fps monitor from red to green. Green color has the longest lifespan in amoled, so lesser chance of amoled burn.

    v1.00 Initial release
