2.3.4 Unlock Screen
In order to prevent unauthorized use, you can set your phone screen lock. Elected to
use this function, every time you light up the screen, you must draw your unlock pattern,
so that you can unlock the phone, and then send or receive calls.
Users can clear the unlock pattern (see "Security Settings").
