Why don't you have another option for aggressive doze mode as for me standby drain was better. Don't know if it's the March update I've just updated my phone to or the app but not getting standby like before.
Seconded. I feel the standby time on 6.62.25 was better than 6.62.50, and I really didn't have issues with the notifications before not coming through, so It would be nice to have the option to switch back and forth.

I also think that the Net Speed section is not needed and adds a bit of bloat to the UI. It just feels a bit out of place within this app and I doubt many people even use it (I could be wrong though).
These are noted. I will put the options in the next update.

Hello, love this app! Thank you for the continued development and continue to add features!
Unfortunately I ran into a issue I believe on version 6.62.25 and up. The phone would spam me with "send error report messages" causing the phone to be un responsive and continuously vibrating.
The app the was getting the error was samsung pay, I believe because I had quick access from the lockscreen enabled in the samsung pay settings. Turning off that option seems to have resolved the issue. So Going forward could you possible add options to exude specific apps(I believe it was the new doze feature since I think that's when the issued started) here is the bug report if it helps:

Is galaxy max hz also crashing?


Any chance to make CQHD (or any other resolution close to QHD) resolution to fill the entire screen?, In order to use 96 or 120hz. Im on S20+ using adfree app. Thanks
Thank you. Unfortunately, NO if you want to keep the high refresh rates. You might be better off using FHD+. Personally, I don't find the CQHD quality better than FHD+. But it has advantage when watching videos in youtube - you will have higher than 1080p options

Thanks for the new update to fix Hz going down with prolonged input
Can you make it so that it does the same behavior when using S-Pen? It still drops down to 60Hz from 120Hz when writing something in Samsung Notes, but it remains at 120Hz when scrolling using fingers

Can you explain how the Moderate and Aggressive work? I know that it has something to do with the amount of time that it puts the phone to sleep, but would like to hear more from you

I don't believe so.... all I know is the problem started when I updated to 6.62.25. It's very easy to see the problem because the phone immediately starts locking up and vibrating, I was able to catch the screenshot of the error pop up but it took me many tries because it goes into an error loop I guess and the pop up window doesn't have time to stay displayed🤷‍♂️. When I got the issue the first time after updating the galaxy max hz app (to I think 6.62.25), I Uninstalled the galaxy max hz app and immediately problem stopped. You released the update (6.62.27 I think it was), I installed that.... no issues.... activated adb and instant locking up and vibrating again... i Uninstalled the galaxy max hz app again... issue stopped. Saw you released 6.62.50 tried that, same thing. Then I was finally able to see the error pop up window and saw it said samsung pay has stopped. So I thought that maybe because samsung pay was enabled on the lockscreen that somehow was crashing from a setting in your app. So I turned off samsung pay quick access from the lock screen installed 6.62.50 and enabled adb and everything has been working flawlessly all day. If you want me to try anything else I will but I think that was the issue.
Thank you for looking into it!

Edit.. okay so I re enabled the quick access from the lockscreen on samsung pay and haven't had any issues in a few minutes. I updated the galaxy max hz app to 6.63 with aggressive doze on and still good. Idk I'll have to keep playing with it and see if the issue Arises again.

After the latest update, the adaptive refresh rate becomes really erratic. I've noticed even when scrolling sometimes, the phone drops back down to 60hz and won't switch back up to 120hz. (This is relatively noticeable on my phone's app drawer and main) It is rather inconsistent even when it detects a touch input, it stays at 60hz and will randomly dial back up to 120hz at times. This makes the adaptive mode really uncomfortable to use unlike before.

Also, the refresh rate stays at max 120hz on the notification shade even when I've idle for more than my allocated delay time.

Tried resetting both data and cache on several occasions but to no avail. This problem only crops up in the recent update.

its very good! I have a question. When i watch twitch or YouTube livestream, adaptive mode doesn't work because of live chat.
I think it recognizes live chat as touching screen.
Could you please fix it? thanks!

v6.63.10 now available.

v6.63.10
-Fixed few erratic behaviors on Adaptive mod that appeared in v6.63.00 release.



I found a small bug. Adaptive mode works perfectly but not in Lockscreen. In Lockscreen its always in highest refresh rate
Seconded, adaptive is more erratic with this release.
I also noticed this
Yep mine goes down to 48hz while scrolling app drawer but jumps back up when back on home screen.
I noticed that too. The refresh rate stays at max 120hz on the notification shade and even if I leave the notification shade and return to the home screen it stays 120hz



This is the same behavior as the native Adaptive motion smoothness mode.
But I'll check if I can make an improvement on this.

    I updated to the latest version. Another weird behavior I noticed. On Instagram 'Horizontal' scroll of Pictures, the RR stays down at 48Hz...But I scroll vertically (page up-down), then the RR goes up.
    ****The screenshot here shows, when I am in d middle of a Horizontal swipe between 2 pictures in Instagram, My finger is touching the screen, swiping left.
    View attachment 5294749

    I noticed that when you scroll through comments on IG it stays at 48 for me

    Another abnormal adaptive behavior. When toggling off overlay to appear on top, the adaptive refresh rate seems to be stuck on either 60 or 120hz. Appear on top overlay needs to be on for adaptive to function normally but will still be stuck at times.

    Also, the refresh rate will be stuck at the last refresh rate when the device is unlocked even with power saving mode turned on or off. On Beta3 .10, it was working fine but after the recent .15 and .17 hot fixes seems to break the adaptive mode.

    Please do something with the youtibe all the time in 60hz and the fact that adaptive didn t works well,lags when switching with delay
    I have s20 fe if it matters

    For those who are experiencing issues in v7.10, you may rollback to previous stable version v7.00.36 for the meantime while I am investigating the issues in v7.10. Thank you.

    Hello my app will not download the updated version. It's telling me this..
    Same for me
    Having the Adaptive mode dying on my S20 FE Android 11 ... all battery optimizations off for Galaxy Max Hz but still seems like some aggressive doze/task killer type thing is interfering with it.

    Sometimes hz notification reports nothing as well as if it doesn't wake up correctly from screen off. Reported this and got no reply.

    EDIT: Upon further testing I've noticed that opening or moving the new "Bubbles" feature locks the screen in 120hz mode until next lock/unlock cycle.


    I have the PRO version of the APP. I needed to restore the device and now I can't pass the adb on GALAXY MAX HZ. What should I do ?
    Can you provide more details of your adb issue? What's the error shown in adb?

    • Can I add the CQHD+(custom QHD) resolution that supports 96hz/120hz for Note20Ultra or S20 series device?
      Yes, this option is added as requested by some users. Connect to the internet before opening the app for the first time -or - clear the app's data and open it while connected to the internet in order to load the profiles from my server containing such resolution. The server 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
        Note: Since this resolution is not defined in the system, the system does not automatically recognized this as supporting High/Adaptive refresh rates and resets the refresh rate mode to standard on every reboot. Will be working for a workaround for this in the future update.

    I can't seem to find that 🤔is now qhd and 60 rate can someone help 😁😘 note20 ultra
    Do you mean CQHD+? If it's missing, try reload profiles option in the 3 dot menu.

    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***

    • 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.

    v6.64.00 is up! :)
    - Added option to keep motion smoothness on power saving mode - either enabled manually or by the system/adaptive power saving

    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


    Hello everyone.

    v6.61.10 build is now up - should fix bug on refresh rate profiles not properly loading introduced in v6.61.0*.

    v6.61.10
    - Fixed bug on refresh rate profiles not properly loading(bug inroduced in v6.61)
    Clearing app data is highly recommended after this update

    Thanks to all who reported the bug.

    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) during screen-OFF. This will make a better standby power consumption. This works best with "Power Saving Mode on Screen-off" enabled. Doze mode will stay until the device is unlocked. Motion detection will not interrupt this doze mod. The general behavior of doze mode is described below:
      In Doze mode, the system attempts to conserve battery by restricting apps' access to network and CPU-intensive services. It also prevents apps from accessing the network and defers their jobs, syncs, and standard alarms. Periodically, the system exits Doze for a brief time to let apps complete their deferred activities. During this maintenance window, the system runs all pending syncs, jobs, and alarms, and lets apps access the network. At the conclusion of each maintenance window, the system again enters Doze, suspending network access and deferring jobs, syncs, and alarms.
    Some apps notifications are only allowed during the maintenance window except for SMS, those apps using High Priority FCM and those which battery optimizations are disabled. If you want certain apps to ignore this behavior, just disable battery optimization in their respective app settings.​
    • Why I don't have 48hz and/or 96hz on my device?
      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 and also when notification panel is expanded.
      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. On expanded notification panel, it does not go down when you enabled the app's refresh rate monitor and/or net speed indicator - 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.

    • Is the Adaptive refresh rate mod in the app the same as Samsung's native adaptive refresh rate. Is it based purely on touch input?
      For those devices that do not have the Samsung's native Adaptive refresh rate mode, the app's own Adaptive Mod is applied. But for those devices that have the native adaptive refresh rate, the native adaptive refresh rate is applied 'as is', except when you override the minimum refresh to lower than 60Hz .

      Aside from touch input, the app's Adaptive mod also considers the changes on the contents being displayed on screen like the native 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 and specially when using 96hz and/or 48hz. This is an issue of consistency of gamma curves across the different refresh rates. Samsung possibly did less calibration on 96hz/48hz. This also has to do on the hardware tech that is used in the display (LTPS).

    • 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 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

    • How to activate ad-free trial?
      Click the 'Activate Ad-free' button and click 'More Info' into prompt that will appear. Type in "TRIAL" and apply. You will have 7-days to test the ad-free extra features.
      Starting with v7.**.**, activate ad-free trial will automatically prompt when it is still available to 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 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, click the (edit) Configuration section to see the tasker settings/variables available for GMH and the valid values on each.

        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 Activity Profile(Trigger) and another Activity Invert Profile(Trigger) for each of these apps in Tasker's Profile tab, then create the corresponding GMH task following step 1 and link them to the corresponding Activity Profile(Trigger) and Activity Invert Profile(Trigger).

    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.

    Unresolved Bugs:

    • Samsung Pay is reported to be crashing when using this app. Currently investigating on this. I am encouraging anyone who is experiencing this to also send/report the Samsung pay crash log to Samsung.
      Update: Based on my research, it seems that this is happening when using any app that uses a screen overlay.

    Upcoming features:

    • Custom max refresh rate on power saving mode (e.g. 96hz) - implemented in v7.10

    I was looking at screen off refresh rate. Screen on works perfectly.

    On latest Samsung update, security patch December 1.
    Same here, since v6. 01
    You just triggered me to look, battery was going faster than usual but didn't check why yet. But now I know. Although 3.n% is not that much of expect it to be much lower.
    Can confirmed that it works after turning screen off more than 5secs but its not consistent, sometimes it would still shows 96hz and most of the times 48hz doesn't revert back to 96hz upon waking up the screen.


    update : 48hz is working more consistently but still wont revert back to 96hz. I also need to manually turn back on the 'Real-time Refresh Rate' for it to show up again even when the option was already turned on before the screen went off.
    Same here, tried putting the app in exclude from cleaning but it still won't revert back to 96hz.
    Yes i removed and know stop crashing 👍

    my screen off refresh rate doesn't change correctly i noticed it's inconsistent sometimes it does... sometimes it stay at 48 for long while after....needs work
