Friends -- Something odd has started happening with my GS3. When I'm on a hands-free call via Bluetooth and my car's speakerphone system, and another call comes in (call waiting), and I switch to the new call (while disconnecting the other call), the new call goes into private mode and I cannot use my car's hands-free speakerphone system. I experimented by connecting with a different car, and had the same result. Is there a setting somewhere in the phone that controls this? Thanks!
