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
