I got a new screen! It costed a fortune Before I got it I was REALLY frustrated..
My tablet is a touch screen (it will sense anything besides just a stylus, so you can write with your finger, a regular pencil, etc.) so it thought that it was being touched every 2 seconds in the same place because the glass that was cracked was tricking the sensor or something and it kept clicking rapidly in the same place and it was almost impossible to use..
