i was pretty sure it was a light i thought, i know there is a auto sensor somewhere, mabye that is what it is, but go to settings->sounds and notifications->then notifications->and for Event select something like messeging and you will se the flash light option.

other than that, ithought i saw a video somewhere where it was a green led in the earpeice. but since i cant get it to work, idk.
