I know that there was previous a Game Mode on Samsung devices. I can't seem to find it in the performance options on One UI. I've searched the Internet for a bit and there was a way to activate it with the Routines app from the Samsung store, but now there isn't an option for Game Mode on that app either. Is it gone forever or is there some other way to turn it on?
Hello. Are you looking for the menu that allows you to limit FPS and resolution for games, or the one that lets you take screenshots of games and put a screen lock?
The former is inside of Game Launcher on all Galaxy S/Note phones running OneUI. For the other stuff there's a perm notification for game tools/booster. You might need to manually add games to Game Launcher.
