Input lag on my phone (version 2)

Alright, so it's been a while since I got my galaxy s8.  I noticed that there was a lot of input lag and I made a game support thread about it about 5 months ago.  P1kachu had recommended some methods of reducing input lag, but unfortunately, none of them worked.  I even decided to play the game for 5 months like he said, and nothing has changed.  I wonder if I can find a way to reduce input lag on my phone now.  Please provide any suggestions.

Edit: I forgot to mention that I've tried changing the screen resolution, messing with developer options, and using the Game Launcher.  Nothing I have done has worked though.
