Hi, So I'm finally at wits end over this thing. I bought it last year (April 2013), and I love it, but a few months ago a small section of my touch screen quit working (the far right mid-section). It was annoying, but I never use the tablet for typing so it didn't bother me. Mostly I use the touch screen to scroll or zoom, which I could do on any other part of the screen. Well now I'm at a big problem. The only part of my touch screen that is working is the lower left-hand 25% of the screen. I can't scroll and can only pinch-zoom in that section, which is a major issue for me. Any ideas of how I can fix this? Thanks..
