I just picked up a Punk colored (AMAZING!) Otterbox defender at my local ATT store for my iP5. I love it, and it is my first Otterbox product. But I am having two problems with it: When I use it, I can feel the phone bumping against the inside of the case. Is this normal? I know i put it on correctly because I had the person at the store put it in and did it myself again at home. Also, the screen protector made the touch screen a lot less sensitive. Is this normal?
