I keep getting a notification tone and have no idea which app it is coming from. My phone sounds the notification, but nothing ever appears in the status bar to let me know which one it is. I have sooooo many apps, and have been through them all and still do not know which app is playing this annoying notification. I've looked at the list of tones I have, but none of them are the one that keeps going off! Anyone know of a way to detect active notification tones?
