Section 2: Understanding Your Phone
Front View of Your Phone
The following items can be found on the front of your phone.
1. External speaker: Used to hear the caller.
2. Proximity and light sensors: The Proximity sensor
detects how close an object is to the surface of the
screen (such as when your face is against the phone
during a call or the phone is in your pocket), locks the
keys to prevent accidental key presses, and turns off
the screen. Light sensors use the ambient light level to
adjust screen brightness and contrast.
3. Front-facing camera lens: Used to photograph yourself,
or view yourself while video chatting.
4. Display: Shows the information needed to operate your
phone, such as the Application Tiles, icons, and so on.
5. Back key: Used to step backwards when navigating a
menu or web page. Touch and hold the Back key to
view the current screen and up to six screens most
recently displayed.
