The applications you installed in your phone may use their
own notification icons while running in the background.
To open the Notifications panel:
·
Drag the Status bar down from the top of the screen.
·
OR press menu key on Home screen.
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).
