Mine is the same way and I checked my son's and his also has this as well. It's so slight that you can hardly tell but if I rub my finger up from the bottom buttons up on the screen I can just feel the bottom is slightly raised up. Is that what you are refering too? I've had mine (refurb) just over a month and my son's (brand new) almost a month now. I noticed it when I first got mine but figured it's just how they are made. I have no issues or problems from it. It's so slight that I'm not even sure if it's that it's raised or I'm just feeling the gap between the screen and the buttons on the bottom. It does feel like it's slightly raised though. Also I notice it more on mine which has a screen protector even though I can also feel it on my son's which doesn't use one. It just seems more so on mine. Again not enough to cause me any issues.
