When i first got the phone two days ago, i would receive this "Droid" voice when i received a new alert and I could also read it across the top of my phone. That was perfect but now I am not able to hear the alert. All that happens is a flashing green light and thats it. No vibration of noise. Please help me get the phone back to were it needs to be. i have checked the setting but I am lost at this point. I need someone who understand the Android Operating system.
