    I just noticed there is another sensor on the front ... I know there is the front camera, the light sensor, and then the notification light at the top.. but next to the light sensor there is something else. It light up dark red for a few seconds last night. Anyone know? Thanks.

    Its an infrared sensor for proximity; turning the screen off when you are on a call and in-pocket detection
