“High Technology” sensors and accelerometer are few of the exciting features in iPhone. The sensors are sense the environmental changes and make iPhone respond automatically for improving iPhone experience and the battery life of the device. There are two built in sensors to make this happen :
The Proximity Sensor
This sensor detects how close the screen of the phone is to your body. This allows the iPhone to sense when you have brought the phone up to your ear. At that point, the iPhone turns off the display in order to save battery. It also stops detecting touches, as to avoid unwanted input, until you take the phone away from your ear.
Ambient Light Sensor
This sensor detects the brightness of your surroundings and adjusts the iPhone’s display to bright or dim to maximize visibility.
Built-in accelerometer make iPhone respond to change the display from portrait to landscape(or vice versa) when the user rotates the device from vertical to horizontal(or vice versa). As you change the way you are holding the phone, the iPhone switches the display. How smart can it get?
Basically the iPhone is not doing anything other phones aren’t capable of, but it will let the iPhone do it without instruction from the user.
