My HTC one connects fine with the bluetooth in my car and the functions works fine. But when I make a call the sound is much too low. Driving at slow pace I can barely hear the words from the person I am calling. Neither the volume control in the car nor in the phone solves the problem. The bluetooth in my car worked fine with my previous phones ranging from iPhone, Galaxy S3 to HTC 8x.
Any ideas?
