First out is a multi-purpose component that connects the earpiece speaker, IR blaster, and a sensor array hosting the ambient light sensor and a second IR sensor.

The placement of the two IR sensors on either side of the earpiece speaker explains how Samsung’s new Air View/Air Gesture feature operates. By comparing IR light reflected from your hand into each of the sensors, the phone can track sideways motion as you gesture without touching the screen.
