You can't believe the frustration I had with my brand new device. Directly after unboxing it, I removed the screen cover. The screen went haywire and kept sensoring touches all over, especially close to the borders. I pulled my hair in great despair and started to prepare for some kind of repair. However, after a few days I realized that there was a second screen cover! Out of all my devices, probably 20 or more, I have never seen a product shipped with a double set of covers before. My advice is thus to double check your screen for a possible second screen cover.
