My S4 already has a tiny noticeable hairline scratch at the back part next to the speakers after a week without a case. Yikes! Don't know how it got there though, im very gentle with my phones, even treating them like they were my baby i have OCD so this bothers me alot. Also noticed the bezels are easily scratched too. decided to buy a TPU case a few days ago as not to scratch the back part more. Any of you guys have scratches on your S4s?
