I have had the phone replaced twice and the problem remains. When I am at work, any incoming call goes straight to the in-call screen, looks like the call has been answered but it has not. This is without the phone ringing, vibrating, swiping to answer, actually not touching the phone at all. The phone looks like it is on a phone call but the caller just hears rings and eventually goes to voicemail. I've tried everything, wiping the phone, factory resets, reseating sim card, new sim card, battery pulls, and even new phones. I'm thinking it has to be some type of interference but not sure how. I turn off wifi and keep it from searching for networks but that didn't work. Any help would be greatly appreciated.
