iPhone 4 Teardown

• Accelerometer detects when the user has rotated the device from portrait to landscape, then automatically changes the contents of the display accordingly

• Proximity sensor detects when you lift iPhone to your ear and immediately turns off the display to save power and prevent inadvertent touches until iPhone is moved away

• Ambient light sensor automatically adjusts the display’s brightness to the appropriate level for the current ambient light, enhancing the user experience and saving power at the same time
