I hate screen protectors 😤 I've never used one on my iPhones, but all was fine with iPhone (3/3G)4/4S/5/5S. This mess came up after Apple has used the curved screens after iPhone 6.
I was waiting for iPhone 12 only to (finally) don't have "hairline scratches" on the new screen because I though "it's flat, so more resistance, like the iPad from model 1"... but looks like no changes from the iPhone 10/11... damn!
It's a shame that only put your phone in the pocket can produce this hairline scratches on it, it wasn't there with iPhone 4 and 5, so I was wondering why the hell Apple is using this soft displays only to save it from big falls, but I think is bettere to use a rear cover to protect it from the falls and use a harder screen on front, so it will not have tons of hairlne scratches on the front that is where you look all the time.
...and all the iPads still have a strong display like the iPhone 4/5! This thing is driving me crazy!
