I've had the phone for about three weeks, and I've had the following problem since I bought it: When attaching to blue-tooth in my car, if I'm on one call, and another call comes in, the speaker goes dead. I have to toggle blue-tooth off, and use the handset, plus it drops the first call. I've had another android and not had this problem. I've searched the net for this issue with other phone, but haven't found it. Anyone have any thoughts? I'm rooted, and I already wiped the phone and restored it, still have the problem. Can't swap calls, without losing bluetooth connection.
