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

[Deleted member 2086469]

Hi @tribalfs thanks for such a great app! I purchased the ad-free version because I like your work!

One question from me: If I only want to enable this feature "Force lowest refresh rate on screen-off/AOD." and nothing else (meaning the normal usage follows default stock behavior), is it just by toggling the Force to Lowest Hz option in your app, leaving the rest untouched?

Also, seems not mentioned, do I need to exclude this app from Battery optimization which I just did?

 

[tribalfs]

While on home screen, the refresh rate sometimes gets stuck at max value (96hz in my case). Is it an expected behaviour?
Edit: I don't keep the refresh rate display on at all times. So, whenever I enable refresh rate monitor from quick panel, the refresh rate gets stuck on home screen. If I open any app and get back to home screen, the behaviour is normal.

Yes, but only when the notif panel is expanded and the app's refresh rare monitor is enabled at the same time. It should drop after closing the notif panel.
More info in FAQs.

FAQs:

• In my Note 20 Ultra, the 96hz setting drops more regularly to 60hz than 120hz. Is this an expected behavior?

It's the stock behavior. It's probably because of the relatively larger gap of gamma curves between 120hz and 60hz than between 96hz and 60hz. Samsung needs to fine tune these gamma curves across different refresh rates so users perceive consistent brightness level when refresh rate switches. Otherwise, there will be visible flickers which our eyes are more sensitive when on a darker environment. Seems Samsung hasn't fined tune yet 120hz->60hz gamma for darker environment as 120hz switches to 60hz only on a certain (high) level of brightness.​

​

Update: It seems Samsung has improved this behavior in its Nov 2020 update. This possibly the "Improved battery usage time" in its changelog.​

​

• What will happen if I uninstall this app?
  The last set max freq will persist after uninstall. Set the max refresh rate to 120Hz first before uninstalling to keep stock refresh rate.
  Update: Not anymore persisting since one ui 3.0

• Why 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 Power-Doze Mod work?
  If enabled, the power saving mode will automatically turn-on and the device will quickly enter into Deep Doze (except when charging) both during screen-OFF. Power saving mode will automatically turn-off once the screen is turned on again for atleast ~5 seconds, unless when it was priorly enabled.
  
  App notifications are only allowed during the maintenance window except for SMS, those apps using High Priority FCM and those which battery optimizations are disabled.

• Why I don't have 48hz on my device?
  Currently only the following Samsung devices have 48Hz enabled:
  • Note 20 Ultra
  • S21 Series
  • S20 series excluding FE (but was removed by Samsung in OneUI3.1 update)
    Note: If you are still on OneUI3.0, please advise me so you can load the refresh rate profile which includes the 48hz

• In Adaptive refresh rate mod, I set minimum refresh rate to 48Hz but while watching videos, refresh rate only goes down to 60Hz
  In 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 when expanding notification panel and in games.
  In 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.
  
  In 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 smoothnesswhile playing.

• 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 adaptive refresh rate mode. 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 when using 96hz and/or 48hz under low brightness. This is an issue of consistency of gamma curves across the different refresh rates. Samsung probably did less calibration on these refresh rates. This also has to do on the hardware tech that is used in the display (LTPS).

• 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.

• 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 or with Samsung's built-in threat scanner powered by McAfee.

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.
Please include your device model number, OS version and app version.


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.

- 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

There is one small thing that I'd like to raise. In v6.62 whenever the keyboard is in use, the refresh rate remains at lowest (60hz for my S20+), which is great in saving battery as sometimes I need to make really long text. In the latest version (v6.63) if I hit the keyboard, the high refresh rate is immediately activated, which is not necessary since nothing is moving much. Can you bring the old feature back in the next update?

I didn't expect this change in v6.63.* since the implementation was just the same. But I will double check

Hi @tribalfs thanks for such a great app! I purchased the ad-free version because I like your work!

One question from me: If I only want to enable this feature "Force lowest refresh rate on screen-off/AOD." and nothing else (meaning the normal usage follows default stock behavior), is it just by toggling the Force to Lowest Hz option in your app, leaving the rest untouched?

Also, seems not mentioned, do I need to exclude this app from Battery optimization which I just did?

Yes
Yes, you can enable batt optimization but allow background activity.
Thank you.

Thanks for this app, I always felt like my S20U display was smoother at 120Hz than my N20U due to the adaptive refresh of the Note vs the static 120Hz on the S20U, I could see slight stuttering opening folders on the Note and just ddn't have the same fluid feeling as the S20U, now by setting the Note to 'High' forcing constant 120Hz it has the same smooth motion as the S20U, not noticing any battery hit either

v6.63.20 is now up!

-Tweaked adaptive behavior on video apps on non-natively adaptive devices to avoid/minimize flickers specially on videos with live chats, live captions and animated overlays.

- Minor adjustment in deep doze mode

Thanks for the quick update.
Unfortunately, I am still seeing refresh rate switching when caption is enabled? Just tested on Prime Video.

After this update it started dropping to 48hz again while watching a TikTok, and the frame drop is noticeable because those videos' framerate is more than 48 (I think 60).

Hi. I can't use PayPal because I live in Turkey. For this reason I cannot purchase the program. How can I buy outside of Paypal? I cannot use the stable program in the free version on my flat S20.

Set minimum to 60hz then. I prefer the 48hz drop when watching videos. Saves lot of battery.

My prime video is perfectly playing without any flicker even when the captions are on.

 

[Deleted member 4685262]

I've not had any issues with 48hz while watching videos... Whether it's on Amazon. Netflix.. Facebook... Tiktok... So don't know why people are complaining.

 

[android_htc]

My prime video is perfectly playing without any flicker even when the captions are on.

I've not really noticed any flickering with this version or the previous.
I was just reporting that the refresh rate was still changing constantly when different conversations are detected; if this is still the expected behaviour and cannot be changed, than fine I would probably need to watch videos without captions.
I was just concerned about battery life due to the constant switching when watching a movie or long video.

Hi. sorry if this was already asked in the previous 32 pages. Latest version, paid, the "screen off mod" Force lowest hz keeps turning itself off. What would cause that?

 

[Elhombree]

Thank you for this app, I have recently purchased it but i have some strange issues regarding force lowest hz while screen is on. Its like the one ui launcher gets unresponsive and crashes, for example while in settings when i try to press a category i have to press several times and it doesnt go in the setting and when i scroll up to go to homescreen after that one ui crashes and reloads. This doesnt happen when i toggle it off. Using s21 ultra

I can't currently think of its connection but will investigate more
Few questions:
Do you have the latest version?
Did you perform the adb permission setup or not?
Thank you.

[Doctor_3825]

Has anyone had any luck fixing the weird color difference between 120 and 60hz? Or is that just an issue with how the S20 handles the display?

 

[pepo187]

I uninstalled your app and everytime I get edge light notification my screen stutters like on 48Hz or something...Jesuuus...how can I fix it?

 

[dusanl]

Thx for this awesome app. Is there posibility to reduce battery usage of this app. Its like 2% on me (I know its not that much but...). On version 6.60 (initial version with adaptive function) it was like 0.4%. Btw I am on g985f.

 

[tribalfs]

Has anyone had any luck fixing the weird color difference between 120 and 60hz? Or is that just an issue with how the S20 handles the display?

Yes, on your 2nd Q. But I its weird for me too thinking that these 120hz and 60hz are the primary refresh rates of the phone. I will understand if it's happening on 96hz or 48hz.

I uninstalled your app and everytime I get edge light notification my screen stutters like on 48Hz or something...Jesuuus...how can I fix it?

Definitely not because of the app. You can try clearing edge lighting app data.

That % is very relative to the other app's usage.
Give it time to settle.
I am highly recommending to use the phone's built-in batt stats in case you don't.

 

[Elhombree]

The latest update did nothing to solve my problems with The app. Still having one ui crashing when 96-48hz is enabled and lowest hz enabled/disabled. When i swipe up to go to homescreen it crashes and homescreen reload no matter where i swipe up from. My Phone absolut vibrates outta nowhere sometimes.
