Updated to ios 11 and began to experience ghost touch!!!! I cannot even unlock my phone… i cannot usee it!!! How to fix this?! My friend is also experiencing it! Eventhough she didnt upgrade ios!

You sure it is caused by the iOS 11 update? Usually ghost touch means a replacement screen has been installed on a bent / dented frame or a damaged screen is being used.

I got a same problem for 2 years. If it’s happen, I just push on top right screen until the ghost touch stop. How to check if its okay, you push the lock button to lock then push again. After that you try slide your screen to your right and stop at the middle then hold for a moment. If its stay or go along with your finger movement, problem solved. If not, follow first step again and again.
