Very weird thing happened to me this morning.
I was listening to music with the earbuds...took the earbuds out of the phone...tried to make a call and ZERO sound from the ear speaker.

Putting to speaking phone I heard the dialing sound...plugging the earbuds back...didn't hear anything.

Rebooted the phone several times and went straight to the phone to dial...still no sound except from the SPEAKER.

Eventually, it started to work again...anyone else experience this?
