The pressure sensitivity was off by a mile, it was indicating i was constantly putting pressure on the left of the screen, leaving the entire middle and right useless. The buttons wouldnt work, i couldnt scroll, and i tried turning it off/on repeatedly. I was so mad. This morning i woke up, still mad, and gently slapped it (kay mayb it wasnt that gentle), and it worked again. ughhhhhh thannkkk goooddd #rant
