I had a problem with the color banding on the screen although I looked very good at the phone. I have no idea when it happened, but it's annoying. what can i do for this problem? More importantly, I do not know if the problem is software or hardware.

A Samsung Service Centre or Samsung Experience Store will be able to help you further with this too.
