Nexus 7 UI Issues

I recently got a Nexus 7. After a while of using it (I'm on 4.2.2)the touchscreen becomes inaccurate (hear me out). When I try to go home it selects something a little above it. It's like the area of where you touch is off. Anyone else have this issue?

Perhaps try flexing the device from the lower right corner and the upper left corner; similar problems occur with apple mobile devices; may work may not
