I have encountered an issue. I've downloaded a Touch Screen Test (Siriuth) app from the play store and started sliding my finger across the screen and everything was perfect no skips no nothing, but noticed that SOMETIMES the phone wont register my finger taps on the right side near the edge of the bezel while on the left side it would register every tap 100% of the time. Tried playing with the sensitivity setting lower/higher and no change. I don't use protector. Can anyone confirm this? Really want to know if it's a software bug or my hardware is faulty.
I don't know if you found your answer, but have you noticed there's an onscreen pullout tray on the right side that you can customize? Perhaps you were tapping the tray edge instead of open screen real estate.
