You're not the only one. I've expended this last 3 days trying to figure it out, and I think I found the solution. (Need computer for this)
On your phone go to:
About device> Press several times on Build number (to activate Developer options)> go back to settings> turn on Developer options> turn on USB debugging.
On your computer:
Download and install:
Downloads for Mac:
Debloater.v.x.xx.dmg
Android.zip
Downloads for Windows:
Debloater.v.x.xx.exe
ADB for Windows
Install the app and drives, plug in your phone> open debloater> click read device (top left button)> click filter> type this in: GameOptimizer.apk> check it> click apply!
And since I did this I Can play normally on my S7, without that annoying over saturation.
