I’ve read and experienced myself that the iPhone X screens are NOT as scratch resistant and do not stop smudges as much as previous iPhones. Despite being very careful and using it no differently than my previous iPhones, My last iPhone X was HORRIBLE. Scratches like crazy and smudges all day all night. But recently I got it exchanged for a camera dust issue that they couldn’t fix or something so they just gave me a new one (white box). And while I haven’t used this screen for More than maybe a few months at most, it just seems more durable.
