Why does my Note 4 keep on ringing for notifications?

[AC Question]

I just got my note 4 phone and I have to turn down the sound for notifications or my phone just keeps on thinking that I have notifications. If I do have notifications I don't even know what/where they are.

That is odd -- I would try resetting the phone (factory reset) as it sounds like something is majorly glitched.
