I've had my Nexus 7 for about 2 months now and I seem to be experiencing a couple of build quality issues. The reason I'm stuck is, I don't know if it's enough to return it for a new model. The problem seems to be getting worse too. It's a bad creak on the back of the device. The whole thing now flexes slightly and just pushing with a tiny bit of force on the screen triggers it. It was originally only when the device heated up but now it's practically all the time. I've noticed too, from reading the manual pre-loaded on the N7, it's around the NFC area. My real question to you guys is, is it enough to return it? Even the borders creak now and I just simply am not sure if they will let me. Have any of you guys had this problem? What did you do? Please Help!!!
