I have been having issues with the Voice Control starting all by itself. It apparently tried to FaceTime someone last night while I was asleep...phone was on the bedside table. I can tap cancel, move on to another task (a text, maybe) and Voice Control will interrupt and start again. I use the top button to lock the phone, but it will override and start. I believe it has to do with the Home Button malfunctioning, because at the same time I have had the Voice Control issue, I am also having problems getting the Home button to work when I press it.
