I just got a Samsung Galaxy Note a few weeks ago and really like the phone. The problem is that I get notifications for non-events or phantom events day and night: the phone makes the notification sound but there are no new messages, lost calls, or anything; the notification bar is empty and there's nothing showing on the screen.
I've changed the alert sound and the funny thing is that the one that keeps on buggin me is the default whistling sound that came preloaded with the phone.
Updated to ICS 4.0 and it is still happening. (I'm still running the Gingerbread stock build.)
Any ideas beyond resetting to factory settings?
