Locking your smartphone
If you will not use your smartphone for a while, briefly press the power
button to lock access. This saves battery power and ensures your
smartphone does not unintentionally use any services. Your
smartphone will lock automatically if it is not used for one minute
(depending on your settings).
Waking your smartphone
If the screen is off and the smartphone does not react to any taps on
the screen or front panel button, then it has been locked and is in
sleep mode.
Press the power button to wake your smartphone. Unlock your
smartphone by sliding your finger from the bottom of the screen to the
top. Unlock and access the phone by sliding your finger from the left
of the screen to the right. Unlock and access the camera by sliding
your finger from the right of the screen to the left.
For additional security, you may set an unlock pattern, a set of dots
that must be touched in the correct order to access the smartphone.
Open the Application menu and then tap Settings > Security >
Screen lock. If you forget your unlock pattern, please refer to Unlock
pattern on page 65.
