So, I just had my Zagg Screen Protector installed on my band new Nexus 7 (by the most awesome installer at Best Buy - she is the best), and I just began using my Zagg Screen Protector for the first time, and I noticed something a little odd. While, there aren't any air bubbles, nor specs of dust, there is one thing that is very strange. In a couple of places (one large, the other small), there is like a line that shows, only at certain angles. When I move my head, the lines give somewhat of a thin prism effect (that's the best way I can describe it). The lines have no color, it almost looks like a scratch (but that's not possible). At least, the lady a Best Buy, nor I scratched it. In fact, both lines are perfectly straight, and both are perfectly parallel with the sides of the screen protector. What is this?
