Hi, My sister just updated to ios 10 and is experiencing major problems with voice control. Even when she isnt speaking the iphone will call random peopel, turn on music etc. She had siri switched off, so I told her to turn it on, but it doesnt help. Every time she uses the home button something will happen with voice control. So is there any way to actually this it off? I couldnt find it when searching for ios 10. Thank you!
