Has anyone been able to use a bluetooth headset to make calls? I am an able to do so on my S3. I rely on bluetooth calling to make calls when driving. S-Voice requires you to touch the phone to place calls and it doesn't work that well anyway. Also, Vlingo in-car does not work on my S3. I have tried the Vlingo Labs and it is not working either. I am using a Motorolla H730 headset. If someone knows of a solution, please let me know.
