Okay, so I recently got an LG chocolate touch from a friend to use because I have broken my other phone. The calibration is way off. I went into settings to calibrate it, and it lets me press the first x marker that's in the middle, but when I try to press the one in the top left corner the phone beeps at me and won't respond to the touch. No matter where I tap, it beeps. One time I did get it to move to the x after that one by randomly tapping the whole screen, but never got further than that. Help?
