14. Proximity Sensor
detects how close an object is to the
surface of the screen. This is typically used to detect
when your face is pressed up against the screen, such
as during a phone call.
–
While talking on the phone, the sensor detects talk activity and
locks the keypad to prevent accidental key presses.
15. Light Sensor
lets you use the ambient light level to
adjust the screen brightness/contrast. This sensor
decreases screen brightness in dim light.
•
In a bright light condition (outdoors), the sensors cause the
device to increase the brightness and contrast for better
viewing.
•
In dim light conditions, the device increases the screen
brightness to compensate.
