One click for Voice command would be OK for her, because VC would just wait for a command then give up. Unfortunately, her phone has one click for last number redial, and long click to activate Voice Command. She is always accidentially clicking the bluetooth button whenever she is handling it, and for some reason I'm the one it calls. When I answer, she usually has just put the thing in her ear and did not realize she called.
I wonder what controls the BT functions, and how these two phone have it differently.
