My battery door isn't coming off like some others but mine doesn't seem to be "flush"... and I know it's on correctly. It's raised... if you ran your finger from the top of the phone, to where the battery door starts, you would feel that it's raised.. there's a "bump". I'd say it's about 3/4 the thickness of the battery door it self. Here's a picture to show what I mean... Is this normal? is anyone else experiencing this?
