I use my phone to play podcasts through the AUX input in my car. Bluetooth connects, but when I get a phone call, there is no audio through the Bluetooth -- I can dial and pick up the phone from the car Bluetooth controls, but I can not hear the caller; they can not hear me. Instead of being able to use the hands-free feature actually hands-free, in order to talk to the caller, I must fumble with the phone and unplug the AUX jack from the phone before Bluetooth audio will work. This worked perfectly fine with my old HTC Evo. I picked the Samsung Galaxy S3 over the HTC LTE for my upgrade; I'm beginning to wonder if that was a mistake.
