On incoming calls the screen will not lock and not allow me to answer the call. I am unable to slide the "answer bar" across the screen, to answer calls. It won't move. This does not happen on every call but on average about 6 out of 10 calls. I went to the Verizon store and they could not make the problem occur and said they have never heard of this problem. Has anyone else had this happen. I'm trying to determine if this is a hardware problem with my phone of if it is a software problem.
