I bought a Platinum case from Best Buy when I first bought my 3d but after taking it off and putting it on numerous times, it looks like my paint is chipping on the top corner of the phone. Anyone else having this problem? What can I do to fix it? I'm sure there's not much but what if I just got a black permanent marker and gave it a quick touch up? It's not too big so I don't think it would look too tacky. Any advice? Thanks!
