Hello, I'm not trying to make this into a "screen protector vs no screen protector" issue. I just want to know, do you think iphone screens have become more robust and resistant to scratches. This would be more of a question to someone who hasn't had screen protectors and if they feel they see significantly fewer scratches say after a year, than they did after an iphone 3gs for example. I see scratch tests on Youtube every year. And every year they're like "wow so resistant! I used a knife!" however, you do see micro scratches on it when you look at it at a certain angle/light. I used to put on screen protectors on my 4S, 5S, and 6. I stopped caring after. I don't have one on my 7. I see scratches. The difference is I don't care. I'd rather enjoy the phone than be happy about the fact that I can't see scratches under light. But plainly out of interest, are iphones more resistant to scratches on the screen? Thanks!
