After updating to 10, if the phone is just unlocked while you are in the car, you're not even using it for anything, you just have it unlocked, and you then lock it, the car interprets that as a "phone call" and acts as if it is starting to dial a number and then "hangs up" and disconnects.

Very weird. Very annoying.
