Like everyone here, my iPhone 11 Pro Max scratched while in my suit pocket (no keys, pen or anything else) in one day, before I had even received my screen protector. Never experienced this with previous iPhones. I don’t have any pictures but there was one deep scratch and many smaller ones. Very annoying in daily use, especially on a brand new phone.
I was able to get it “fixed” since I was still eligible for Apple Care. Went in to get a screen replacement. No screens were available yet (too new of a device), so they swapped the device. I feel like I got lucky because they hesitated to say that it was a “cosmetic” problem and not a true repair. Either way, bad experience but good customer service. For what it’s worth, they said my phone would be inspected by Apple because it was returned so early and that I may be contacted to know what happened.
Slapped a screen protector on the replacement phone as soon as I got it, so far so good!
