I just received my first lifeproof case yesterday (one of the new colors for iphone 5) and I really like it, except that there's lint (or something) between the screen protector and the phone. I cleaned everything before I put the phone in, but it's still there. Any suggestions on how to get rid of it? Also, I've read that using compressed air on the front cover will help get rid of the few oil slicks that still remain. Anyone tried this with success? I was previously using an otterbox defender and it had oil slicks too.
