Notifications are driving me crazy. My phone will just beep. I have no idea why. If I drag my thumb from the top of the screen to the bottom, all I see is that I have a voice message from 3 days ago. So why is it beeping today? Is there some type of app that will stop all noise outside of the alarm clock, calendar, Text Message and Phone Ringer? I am more than willing to pay for an app that does that. I have disabled the notifications in the apps I can think of. Please tell me how I can figure out what is causing my S4 to beep.
