I tried with turning in automatic, both with the phone app running and in landscape mode and with the phone app not running at all and the screen turned off. In both cases the phone rang normally and the buttons were responsive. They work just fine about 80% of the time. When they misbehave it is seems to be in quiet places like my office -- and I can't make it stop ringing. Nothing I do will answer the phone or make it stop ringing. I wonder if reflashing the phone would have any effect?
