Apple i-phone 4 features

iPhone4 Design

iPhone 4 the is the world's thinnest smartphone. iPhone 4 is about 9.3 millimeters thin. All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass. This is the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever.

iPhone4 Display

iPhone4 Display

The 960 X 640 backlit LCD (Liquit Crystal Display) display having a pixel density of 326 pixels per inch, making it the highest-resolution phone screen. To high resolution, Apple engineers developed pixels so small, a "mere" 78 micrometers across, the human eye can’t distinguish individual pixels. That makes text remarkably sharp and graphics incredibly vivid. IPS technology also provides excellent color and contrast from almost any viewing angle.

Stainless Steel Back

stainless steel band made of Alloy. The band provides impressive structural rigidity and allows for its incredibly thin, refined design. It also functions as both iPhone 4 antennas.

Accelerometer

Accelerometer

iPhone 4 includes a built-in three-axis gyroscope. When paired with the accelerometer, it makes iPhone 4 capable of advanced motion sensing such as user acceleration, full 3D attitude, and rotation rate. Translation: More motion gestures and greater precision for an even better gaming experience.

Camera LED (Flash lite)

iphone 4 has 5-megapixel photos and stunning HD video camera. The built-in LED flash does double duty. When you’re taking pictures, it works as a flash. When you’re shooting video it can stay on to light up the scene. And on the front of iPhone 4, the built-in camera is perfect for making FaceTime calls and shooting self-portraits.

Double Mic and Speaker

While most phones have only one microphone, iPhone 4 has Double microphone. The main mic, located on the bottom next to the dock connector, is for phone calls, voice commands, and memos. The second mic, built into the top near the headphone jack, is for FaceTime calls and for making your phone calls better. It works with the main mic to suppress unwanted and distracting background sounds, such as music and loud conversations. This dual-mic noise suppression helps make every conversation a quiet one.

Multi Touch

With its large Multi-Touch display and innovative software, iPhone lets you control everything using just your fingers. How does it work? A panel laminated on the glass senses your touch using electrical fields. It can register multiple touches at once to support advanced gestures such as pinch to zoom, two-finger tap, and more. The panel then transmits the information to the Retina display below it.
