Samsung SGH-T809 / SGH-D820
Call quality?
I experienced a Blutetooth issue while the phone was in my hand and i was walking, it sounded all choppy whenever I moved my arm. THAT sux. It means the BT on the phone is low quality. My headset works perectly with other phones I've used it on. In any case, usually your phone stays in one place when you use it. Once I put the phone in my pocket, it was fine.
