The glass also features an oil-resistant coating that helps keep the screen clean. The Retina display includes LED backlighting and an ambient light sensor that adjusts the brightness of the screen for optimal viewing and battery life. When you lift IPhone to your ear for a phone call, a proximity sensor immediately turns off the display to save power and prevent accidental dialing.

It has just the right field of view and focal length to focus on your face at arm’s length. So it always presents you in the best possible light.

15. MULTI -TOUCH With its large Multi-Touch display and innovative software, iPhone lets you control everything using just your fingers. How does it work?
