I noticed that even when my battery hatch is closed all the way (and yes, I definitely clicked it into position fully), there is still a small opening between the fake carbon backing (that comes off all the way when you access the battery) and the little plastic piece that slides up and down to allow the carbon backing to be removed. On the top part, where the fake carbon backing meets the top part of the phone (the bit that has the camera on it), there is no such gap. Does anyone else have this? Just want to make sure it's 'normal' and that I don't have my backing on improperly / a defective phone. Thanks!
