Here is one that is new today after installing 4.1.14: Pressed play on an episode, phone lock screen activates after timeout while listening normally through headphones. Then I begin hearing over top of the podcast episode, "unlock phone for voice search". From that point forward, each time I would push play, voice search would activate over top of the episode. Push pause, no voice search activation. Push play, voice search activates. Ended up having to reboot phone to end cycle.
