Hi,

Nice app, congrats.

Do you know if is possible to change the power saving mode settings (AOD, CPU, brightness, 5G, apps and hone screen)?
I'm trying to change them with tasker and secure settings, but not sure they are actually being applied when PSM is activated. Especially the last one, apps and hone, does not get activated.

With the power saving option enabled, AODNotify notifications do not wake up when the screen is turned off

Dear sir,
your app does not seem to work on S20 FE 5G with andrid 13 OneUI5.
(Build G781BXXS4GVL1)
installed the latest version 8.0.0 with adb shell permission.
I still keep getting only 60Hz when moving to power saving mode
Please see screenshot below.

Sorry for the wrong thread posting - thought it was a global one...

Haven't found this in FAQ. I've set an adaptive profile with default 24 Hz min freq. Streaming app I use still falls down to unacceptable 10 Hz on some old bw movies. Does it mean that S22 ignores exact value or min Hz array could be either 24 or 10 and one should set min value a little higher (how much?) not to fall into the lowest Hz range?

If you set 24Hz as the minimum hz in the default settings, it's the phone's native adaptive algorithm that's working.
You said old movies, seems to me that these movies are of low FPS with 10Hz as the closes compatible refresh rate.
Could also be a problem on the streaming app.

Currently I've set system scenario to set standard refresh mode for this app and it works, so maybe I should try to set lower limit down to 30 Hz to see if it would work as well.

I've tried to limit streaming app with 30-120 range, and it always stays at 120. Tried to limit the phone's global adaptive profile with 24-96 range, and the phone wasn't going beyond 60. Strange behavior as for me.

@tribalfs, there was a JuiceDefender app that had a shedule option for autosync like "enable autosync for x min every y min" among many other powersaving things. Is there any sense implementing this someday or maybe you've done this already in another way?

Important Notes for OneUI6.0 (Android14) :
Starting OneUI6.0, installing the app on OneUi6.0 requires doing it via ADB using this command:
Code:
adb install --bypass-low-target-sdk-block galaxy_max_hz_v8.1.apk
You also need to "Allow restricted settings" to the app:
Open Galaxy MaxHz > Go to About app in top right menu > Click the info (i) icon > Click top right menu in the window that will open > Click Allow restricted settings

    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

      Note: It's reported that after a certain Samsung's update, 96Hz on Adaptive Mode doesn't anymore work on S22 while on normal power mode. But still working while on power saving mode on certain brightness level. Unfortunately, this is beyond control of GMH.


    • 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]

      Note: It's reported that this workaround is blocked and not working in OneUi5.0 on S22
    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]


    • Quick resolution switcher
      -Easily switch to any supported resolutions using the included quick setting tile***
      -Tasker plugin support


    • 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.

    I respect your opinion. But it's not that easy. Basically this feature is just exploiting a bug on the system and that bug was already patched.
    Ah OK didn't realise that. Sorry hope I didn't come across too rude, just frustrated was all.
