The Asus-Google Nexus 7 tablet has impressed us with its powerful quad-core platform and a ridiculously low price of $199. Unfortunately, some users are reporting possible manufacturing defects with display that’s separating from the chassis, causing the device to creak when pressed.
Previously, a number of threads surfaced on XDA and other forums regarding dead pixels issues, but apparently, the display separation problem is what we are seeing the most.
It appears, some screws holding the screen and rest of the tablet in place give away after a few weeks of use, causing the screen to rise up noticeably. Some users reported that they can fix the problem by tightening some screws located at the rear of the tablet. The rear part of the Nexus 7 tablet is very easy to pop off and just like many smartphone models; you can quickly snap the cover back into place. Simply tighten these screws and your problem is solved. However, be very careful as over-tightening them may cause the screen to warp or worse, crack.
