Did you try diagnostics via Samsung members app

i did try the diagnostics, it didnt help. i didnt get the error message ever since i restarted my phone, i did try to tho.  i have to restart my phone every time the touch screen keeps delaying and it have been affecting my game play since i cant touch the screen more than one tap

"windowName:ColorFade BLAST d0#6496 isn't optimized for the latest version of Android. Screen touches may be delayed or not recognized." theres no such app named ColorFade in my phone
