    @tribalfs,
    Thanks for the bug fixes, adaptive refresh rate now working for recent, back and home virtual buttons and gesture mode.
    As a future feature, it would be great if you could incorporate the "exclude app" function within the app instead of tasker profile, similar to AutoHz.
    Not sure what happened... adaptive refresh rate for the recent, home and back button worked fine as per above after a clean install. However, I've just realised that it is not working again 😕
    I did toggle the statusbar option, not sure if that has messed it up... Will do another clean install with just the overlay option only.

    Strange. Check maybe you disabled "Allow background activity" on GMH?

    Not sure what happened. I did clean a install again last night and it started working as expected. I did note this morning that I forgot to enable allow background activity for the app, but this has not affected the functioning of the app, it has been working fine.
    However, I have not noticed that the "home" and "back" button (virtual buttons) do not activate adaptive refresh rate from the home screen (seems to be okay from recent menu), see video below.

    Expected behavior when already at home and when nothing is on backstack. Otherwise, adaptive kicks when these two are press.

    Hi I bought full version, could you or someone answer 2 questions:
    Power saving mode on screen off- is it normal power saving mode? Is it normal power saving mode which should set 5G to 4g etc? As I have them enabled but and anytime I turn screen on I can see that I constantly got 5g.
    Also does power saving feature can cause delayed notifications?

    Thank you. It's the normal power saving mode. It's working on screen off, you will see the battery saver icon in the statusbar for a split second right after turning ON the screen. However, switching from 5g to 4g is Samsung's own additional implementation. I am still looking on how to replicate it.
    PSM may delay notifications depending on the app and your usage

    Good morning i have an Samsung S21 Ultra EMEA Version it works great😊👍👍
    Can this App Working on my Galaxy Tab S7+ too? There the same problem in Energy Saving mode to reduce on 60Hz...
    Yes, the app is compatible to Tab S7+

    I want to report a bug
    The auto switch for battery saver when screen is off,after a full charge and disconnect it,it s still on the battery saver and some random bugs like that
    Check if you have adaptive power saving mode enabled. If it's already enabled while screen is ON either manually or by adaptive psm, the app will not turn it off.

    @tribalfs,
    I normally have power saving mode manually enabled all the time.
    I was curious to see if PSM was working when display is off with your app.
    Unfortunately, after turning on the screen I do not see the battery saver icon in the statusbar for a split second as expected?
    I have created a tasker profile to check this behaviour and can confirm that the power saver icon appears for a split second after turning on the screen with the tasker profile.
    But, it seems to be NOT working with the GMH app on my S20 FE 5G as reported by another user as well?

    Turn the screen off for atleast 8 secs. You have to quickly unlock to catch it. If you are still unable to catch it, you can check it using adb. Just execute the following command while the screen is off.
    Code:
    adb shell settings get global low_power
    It should show 1 when PSM is enabled and 0 when not.

    Thanks for the quick response, it is almost impossible to see the icon after unlocking the phone.
    I have tested with the ADB command and can confirm that it is working, returns a "1" when the screen has been off for at least 8 secs - your app is much quicker than the tasker setup!

      Updated to the june patch and everything works as it should using 96 hz adaptive refresh 60 hz minimum refresh and CQHD+. Monitored refresh rate using both the built in monitor in the Dev options as well as the one in the app. 96 hz maximum and 60 hz when idle. Using the latest version of the app on a Samsung Note 20 Ulta 5g Snapdragon variant.

      Props to the dev.

      Amazing App !! you saved me alot of battery with adaptive refresh rate.
      I already got the ad free version after a week of trial, I couldn't live without it.
      Now my S20 hits 5-6 hours consistently each day.
      I would suggest You add battery percentage toggle to the adaptive refresh rate,
      like from 100 to 60 would use 120hz
      59 to 30 would use 96hz
      Below 30 would use 60hz
      That would be amazing.
      Keep the amazing work

      Great App! However found following weird issue. If this app is ON in installed services, then the xbox wireless controller will not work with Mantis Gamepad Pro app (it stops recognizing buttons, etc). Just sharing in case it happens to someone else :)
      Hey,
      I have a problem with my Xbox wireless Controller in games when Galaxy Max Hz service is enabled - for example sticks are not working. When I turn it off in Settings->Accessibility->Installed services->Galaxy Max Hz everything works perfectly fine. Is there any way to fix that?
      Edit: I have also tried with PS4 controller and it behaves exactly the same.
      I have s20 fe 5g.
      Sounds like a similar issue I was having with Nvidia Games not recognizing gamepad inputs when galaxy mhz accessibility option is enabled

      Please check v7.12.11 in-app update. Thank you.

      I did bro, I have installed the latest update. Cleared the data, installed and uninstalled several times, gave adb access. But still the issue persists
      Edit: Fixed. Please check v7.11.03 in-app update.

      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 (after ~ 10 secs)***

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


      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.


      DOWNLOAD LINKS (GITHUB):
      WARNING!!! DON'T DOWNLOAD THIS APP FROM ELSEWHERE. THERE ARE TROJAN-FILLED TAMPERED VERSION OF THIS APP OUT THERE.


      FAQs, changelogs and more information in the next post.👇


      Demo video of v5.4. More features have been added in the later versions

      FAQs:

      • 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) while screen is OFF. This will make a better standby power consumption. Motion detection will not interrupt this doze mod. While in doze, the device periodically enters a maintenance window (MW), during which apps can complete pending work (syncs, jobs, etc.). The device will continue this cycle, doubling the length MW interval each time. The longer the MW interval, the better the battery saving.

        Doze mode may cause notification delays on some apps. It will not affect SMS, High Priority FCM and apps which battery optimizations are disabled.

        Doze mode will deactivate once the device is unlocked.

        Caution: Ensure to disable Doze Mods from other apps when using enabling this feature in GMH to avoid conflict.
      • Why I don't have 48hz and/or 96hz on my device?
        Availability of certain refresh rates is dependent on hardware support and must also be enabled in the system.

        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.
        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.

        Important: When you are using "Priority Mode" in Game Launcher, you should add GMH to the excluded list in order to keep it's background service from being killed when opening a game. Not adding GMH to this list can cause refresh rates to drop to minimum hz and behave abnormally while gaming.

      • When notification panel is expanded, adaptive mod does not go down.
        This only happens when the app's refresh rate monitor and/or net speed indicator is enabled - 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.

      • How the Adaptive refresh rate mod works?
        For those devices that do NOT have the Samsung's native Adaptive refresh rate mode, GMH's own Adaptive Mod is applied. But for those devices which already support Samsung's native adaptive refresh rate, the native adaptive refresh rate is applied 'as is', except when you override the minimum refresh to lower than 60Hz.

        GMH Adaptive mod not only detects touches but also the changes on the contents being displayed on screen similar to Samsung's native adaptive 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 conditions and specially when using 96hz and/or 48hz. This an issue of consistency of gamma curves across the different refresh rates, a display calibration issue. This varies on how finely the manufacturer calibrated the display, which is also influenced by hardware tech that is used in the display. Unfortunately, GMH can do nothing on this


      • Can I disable appear on top permission if I don't use the app's refresh rate monitor overlay?
        Not recommended. Disabling it may introduce issues on GMH's Adaptive mod. It's recommended to keep it enabled and just hide its notification by long-pressing on it in the notification panel and switching it off.


      • Can I add the CQHD+(custom QHD) resolution that supports 96hz/120hz for Note20 Ultra or S20 series device?
        Yes, this option is added as requested by some users. If it's not shown in the app, just click the "Reload Profile" in the 3-dot menu while connected to the internet to load profiles from my backend containing such resolution. The backend 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

      • I enabled Power Saving Mode on Screen-off and the Always on Display (AOD) stopped working?
        Disable "Turn-off Always on Display" option in your device's Power Saving Mode settings.
        Note: You can use this setting to confirm that PSM on Screen Off is working. AOD turn off after 6-10 seconds.

      • 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?
        1. Create(+) a Task - inside Tasker's TASKS tab and give it a name. Inside the Task Edit window, add GMH Action by clicking (+) button > Plugin > Galaxy Max Hz. Inside Action Edit window, expand Configuration section to see the tasker settings/variables available for GMH.

          Go back to Task Edit window and set a value to each of the variable that you want to use by clicking (+) button > Variables >Variable Set > enter the variable name and a corresponding valid value. Ensure to put GMH action AFTER all the Variable Set actions (Tip: Use hold and drag to re-order).

          You can test the task you created by clicking the ▶️ button at the bottom.

          You can create multiple GMH tasks with different variables.



        2. Create a Profile(Trigger) - in Tasker's PROFILES tab for the trigger that you want to use then link it to the task that you created in step 1.

          Tip: If you want to override behavior for certain apps, just create an Application-Activity Profile(Trigger) for each of these apps in Tasker's Profile tab, then create the corresponding GMH tasks (1 enter task and 1 exit tasks) following step 1 above and link them to the corresponding Application-Activity Profile(Trigger). To link the GMH exit task, just long press the linked GMH enter task and press "Add Exit Task" in the options that will show.

      • How to activate ad-free trial?
        Click the 'Activate Ad-free' button and it will prompt automatically to activate trial if still available on 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 don't have a paypal account but I want to buy ad-free
        You can use the "Checkout as Guest" option to pay without registering to paypal.
        If paypal is restricted in your location, you can purchase this GMH Donate app from play store and send to me here on XDA or to [email protected] your device model number and email address so I can send you the activation code. I am currently doing this manually while I am still working on automating it.

      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 attach/send a screen recording* showing the bug/issue and also show your GMH settings in the screen recording. 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.

      The program is very much in conflict with bank programs where the entrance is through a fingerprint. The phone starts to hang very much. Latest version of the program
      The link to the latest version isn't working.
      @tribalfs Thanks for all your work, amazing app!

      I'm having some issue with S21 ultra v6.61 the app is detecting my lowest hz differently each time sometime it detects 60 sometimes 120 (although the actual should be 10).
      Also is there an option to set a specific hz for certain app?
      Could you post the link for 6.61.02! Updating through your app gives the error "there was a problem parsing the package".
      Since last Android Update unuseable.

      Can't switch to ,,Adaptive". Can't even set it to 96hz. I will revert back to 5.30.... That works... but 48hz will be out 4ever i think
      Does this version fix the issues ? Safe to install? And thank you
      No more adaptive refresh rate..allready do the ADB commands and "trial" it was once then gone forever tried to force stop and clear app data..please help
      Same here, I think the dev mentioned that screen profiles aren't being loaded properly but the link seems to be broken to the update that fixes the issue. All we can do is be patient for now. I tried to get back 48hz by wiping and uninstalling but that broke adaptive for me as well
