I can't say when this first started happening to me, other than I THINK it coincides with when iOS was released (or when the beta became available), but now if I am in the car driving and get an incoming call, my phone announces the call by reading out the DIGITS of the phone number instead of saying who it is. I don't use a Driving focus so this happens with no Focus on at all, and yet it only happens in the car. And I can't for the life of me find a way to turn it off. Help please!
