Also, if you are using a silicone case, this can lead to static electricity that could harm your device - including the screen.
I don`t belive in this. I`ve been using silicone case from day 1 and no static electricity problems. If anything it should protect from static.
I think some of having problems with that are wearing "wrong" clothes that cause problems.
