To many of you experienced Android users, you'll yawn at this thread. But to many newbies like myself, who I've heard complaining on this and other forums about their new Note 3 and its continual and unidentified notifications, this may be a help. Basically the problem is, in the General Settings, there is a setting for the Call Ringtone and one for the notifications. So, I and a lot of other noobs, select a call ringtone and one for when they get a text message. The second however will make itself known every time some app gets updated, whenever you get an email (I get 50 or so a day!), and a zillion other cases, many of which are completely unidentified. So ... Here's what I've done to eliminate these annoying continual notification sounds. You go to the Messages App, tap the phone's Menu button, tap the More tab and "Select Ringtone" is the 2nd line item from the top. Tap that and select the sound you want when you get a Text Message and tap OK. Then go to General Settings on the main Home Screen Menu, tap Sound, tap Default Notification Sound, and choose the 1st one, which is "Silent." Now, you'll hear what you chose in the Message app when you get a Text, but you won't hear any of the other zillion notifications.
