Ok. Today is day 8 with my iPhone 11 Pro Max, and still not a scratch to be found. It still looks brand new.
I put it in my pocket with my keys and my wallet, I rubbed my key back and forth against the screen, I did 2 miles of walk run intervals with it bouncing around in my pocket, and vigorously rubbed it on my shirt and pant leg to wipe finger prints off.
I was at BestBuy today to get a pair of Powerbeats Pro's headphones, and was looking at the iPhone 11 Pro display models. The screens where all marked up from people looking at them so I rubbed them both clean and inspected them. they had no scratches on them, so I put them against each other screen to screen and rubbed them together. Then I inspected them again and they still had no scratches.
I am not saying that this entire thread is BS, but I cannot reproduce this problem according to what people are saying about their phones getting scratched from their pockets and keys. And according to some posts that I have read, it's like their phones where scratched by just air hitting it.
This makes absolutely no sense to me other than there may be some defective phones out there along with a combination of some people maybe not being entirely truthful about their scratches.
Also, some people simply may not know that even a grain of salt or sugar on a table could easily scratch any phone screen, or some grains of hard material in their pocket could do the same.
I am not saying that nobody has a legitimate issue, but I am saying that I can not reproduce any scratch issues "so far" with my normal use. Also, normal use may have different meanings to different people.
