Most calls that i make using handsfree from the car result in the person im calling only being able to hear the radio, or nothing at all if that isnt on. They cant hear anything at all that I say. I hang up and call again and its fine. Most annoying! Does anyone know of a fix or is there a Samsung update that will cover this problem. EE told me some months ago that they know of the issue but have no fix as yet and are waiting for Samsung to issue the update.
