Proximity / Gesture sensor - senses the distance of anything from your phone

This is very important when doing calls. The proximity sensor automatically locks your phone during a call when it senses that your head is close to it. This way, you won't be able to press on other buttons while you have the call going. This is also used in gestures. The sensor detects and act based on the gesture it detects.
