Hello there! I have the same issue with mine. I’m starting to doubt if is really glasss or not. I want to polish, but I need to really know if it glass or hi end acrylic to use the right product to try to eliminate the scratches. I’m very carefull to handle the phone (always was) and that’s why I don’t understand the scratches. Just the pocket. No other handles. No keys, no coins, no nothing besides the phone inside of it.
I found a product named “Polywatch” a cream to eliminate scratches from watches…maybe could work
