It seems when I tap near the top of the screen, it registers a touch a few mm above where I tapped. I confirmed this using the Draw 4 Free app. It only does this near the top, so I'm always missing button presses on apps with tabs and such. I can compensate by tapping a little lower than the requested button is. Anyone else have this problem? Should I exchange it? I bought it at Best Buy on Sept. 8th. It doesn't have a light leak, clicking during recording or other bugs and a replacement could have these problems.
