Iv had my mate 20pro for about a month now and the screen is horrendously scuffed, small scratches but everywhere. It's in a case most of the Time and never dropped. I'm very particular so have never manhandled it etc. Iv had iPhone for years with no screen protector on or cases and never had a scratch. Any ideas why it's so bad? Iv heard they have a protective film on but some people say they haven't.
