If there is already a thread on this, please direct me to it or move this query. Hey guys! I have my S4 (Aluminum) for about 2 months now and just noticed a really small but deep scratch last Monday morning. Not too noticeable, but I can see it and can be felt when touched. Also, there's like a rainbow reflection to it now Would you know if the glass should be replaced already or can this be covered by a tempered glass? I stopped using it for awhile now to avoid future damage. Thanks!
