Latch

I just purchased GS350 and connected my Motorola via Bluetooth. It worked fine for a day, and then it periodically switches back to the phone without any notice. I pick up the phone and the call is still connected, but the caller can't hear me or me hear them. I have repaired the phone a couple of times and it works for a day or so. I am now going to delete my bluetooth headset as the second bluetooth device in my phone and see if it makes any difference. Have you had this problem?
