Guys, i bought this iphone 14 pro max on 01/03/2023, and today 01/29/2023 i noticed that it is discoloring on the sides, with some spots turning silver. Does anyone know what i can do?

I’m not sure I’m seeing it. It looks like some dust maybe but are those nicks in the case?

Rocks and debris caught inside case most probably.
