What are the 2 dots near the front camera on the galaxy core prime?

[AC Question]

I thought these dots might light up for stuff. Like one lights up when charging and the other for notifications but they don't do anything and I wonder if they actually have any use.

You can be sure that they do. Ambient light sensor? Proximity sensor?
