S20 Ultra forces 60hz even on games which support 90/120FPS

(Topic created on: 26-04-2020 03:54 AM)

Update: You can fix this problem by disabling GOS. I found this out quite long ago but I forgot to edit this post, sorry about that guys. GOS = (Samsung) Game Optimising Service. To disable it follow this tutorial, I'd highly recommend using the package disabler method and not ADB as the ADB method does not seem to persist after a reboot:

Original post:

@Anonymous User what are you guys doing?? I have tested pretty much every single 90-120FPS supported title and so far only ONE of them actually works, Subway surfers. All other 90/120fps supporting games do not work because for some reason OneUI/Android scales the display down to 60Hz.


I'm guessing Samsung have implemented some sort of API that allows a game to tell the phone to run at 120hz which would suggest why subway surfers works (it's on the galaxy store, maybe they work closer with Samsung) but for me this is unacceptable considering other device manufacturers use a more unified method of refresh rate scaling.


Why is it that over 60fps titles work perfectly on other variable refresh rate phones (Pixel 4, OnePlus 7T Pro, OnePlus 8 Pro, Nubia RedMagic 5G, Black shark etc.) But on Samsung there's some sort of unique API used instead. This is causing fragmentation, you know a lot of developers will ignore this. Why can't you guys just use the same method as other phone manufacturers? I'm guessing android itself has its own variable refresh rate API which is why all these other phones have no problem with scaling the refresh rate up on these titles.


There are many games that support unlocked framerate now and the S20 Ultra as of now can't take advantage of any of them, I guarantee any game you guys are playing besides subway surfers is running at 60fps and you can check this with game tools.


Some games which are able to support 90 and 120FPS but DONT on the S20 series because of the way Samsung has implemented variable refresh rate include:

I paid a lot of money for my S20 Ultra @Anonymous User please get your 💩 together. Also please release an update for WQHD @ 120hz, I don't understand how other companies are releasing phones with both WQHD + 120hz and you guys haven't done it for the S20 series yet even though you make all the displays for these other companies. Thanks.

Try to use a killer app such as "package disabler pro (samsung)", and kill "game optimizing service" application. That will make games run in 120 fps. 


Thanks for the tip, you are correct. I found this out a while ago as I explained here:


Except it doesn't. It has no effect on the frame rate. Pokemon GO still runs at 30fps and I see no difference in the 60fps games
Disabling GOS does enable 90/120fps in titles that natively support high refresh rate on phones like the Razer phone, ASUS ROG, Blackshark etc. I can't speak for Pokémon go but I have tried many 120fps titles that cap at 60fps when GOS is enabled, but work at full 120fps when it is disabled. BulletForce, Modern Combat Versus, PUBG etc. Just to name a few. Android Authority has a full list of 120fps games here:
Didn't see any difference in Altos Odyssey.
And if its not even making a game that's 30FPS into 60fps then I can't imagine it's actually doing anything for the others.
That isn't how this works dude lol. It's not forcing games which are hard coded with a certain FPS to run at higher FPS. It's just removing the 60fps lock it seems to put on games which are supposed to run at higher. Pokémon Go is set to 30FPS by the developer themselves, this is reported on many android devices. Games like BulletForce etc. Have no cap but GOS is capping it to 60, so in this case it allows the game to run at 120. Try it before speculating dude, I have already made an extensive thread on Reddit detailing everything as I shared above and no it isn't a placebo effect, there's nothing to doubt, if you think the difference between 60 and 120fps can even be considered a placebo I don't know what to say, it's a night and day difference. Give BulletForce a try with GOS enabled and then disabled and you will understand, it runs at 60fps with it enabled and 120 when it's disabled.
Got bullet force. Disabled gaming optimisation and all the gaming booster stuff... I don't want to say, I can't see the difference at all. If it running at 120fps.
30 vs 60 is night and day. 60 vs 120 should be too, but I'm not seeing it.
In either case, we shouldn't even have to do this to enable 120fps on games that support it.
Dude you need to disable GOS using ADB or Package disabler pro, look at the Reddit link I sent here a couple posts up.

So I've spent the last couple of hours messing with this . Got package disabler, disabled gos. It does help, getting 120 in altos adventure and 1945, also getting 60 in galaxy of heroes where it was 30...BUT still 60 in Alto odyssey and asphalt. So yeah, it's better but we shouldn't have to bugger about like this . 

Helping Hand

is there any package disabler that is free

many of the free similar apps only allow you to uninstall (to factory version) the GOS rather than disabling - which is not possible via the app management??
