Note 4 notification light problem ?

[iAmDroiDz]

I have had my note 4 for about a week and today whilst I was in class the notification app blinked white instead of its usual blue? I cleared my notifications and after that it went back to blinking blue. It has never done this to me for the period of time I have had it. Is something wrong with my phone ?

Just received mine today, it's doing the exact same thing.
