I recently purchased a Samsung Mesmerize. While on a call I do not get a sound notification that I have received a new text message. It shows up on the screen that I have a new message, but deosn't alert me by sound that I have a new message. I don't know I have a new message until I have finished my phone call. My previous phone would beep, so I would know to look at the screen for a message. Anyone out there know how to make the phone beep or make a sound when it receives a message while on a call?
