Default Touchscreen issues? Possible solution here.

Hey guys. So, I know there's several threads here about touchscreen issues such as dead spots on screen. I too had this problem. I tried several suggestions to see if this could be resolved, nothing worked. Ending up getting it replaced under warranty. Today, before I boxed it up, I did a factory reset. To my surprise, knock on worked. Weird. Brought up Quick Memo, no signs of the dead spots. This could be a temporary fix, I'm not sure. Didn't have time to play around much as I had to get it sent back.

Tldr; make sure you're stock. Go to Backup & reset and do a factory reset. You will lose all data/apps etc. Then, profit??
