When I set my ringer to vibrate, I do not receive any text msg alerts. My phone does not vibrate. I have to constantly turn the screen on to see if I received any text message and there is no doubt that turning on the screen as much as i do kills my battery. When my phone is on ringer, I hear the tone that I received a text, but when it's set to vibrate I get nothing. Please help! :icon_eek:
