One of my biggest (and perhaps only major) gripe I have with my Bolt is the half-assed implementation of Android Auto and the hideous black margins on the sides. I learned that a couple of Bolt owners have received the 14.4.2 update, which "fixes" Android Auto! It supposedly takes care of some other bugs, such as screen freezing, etc..., but who cares about those! Full screen Android Auto! W00t!
