Hello, I have noticed this issue only a few times, however I am wondering if anyone else is experiencing the same issue. When my phone has been locked and I get a call I am unable to slide to answer the incoming call. It is as if my touch screen is not working. I do not have a screen protector on it. If I press one of the side buttons then try to slide to answer it will work. Anyone else having this issue? I am hoping that it is a software bug. Thanks!
