Locking and unlocking the screen
If you do not use the phone for a while, the screen will be automatically turned off and
locked. This helps to prevent accidental taps and saves battery power.
When you are not using your phone, press the
Power/Lock Key
to lock your
phone.
If there are any programs running when you lock your screen, they may be still running in
Lock mode. It is recommended that you exit all programs before entering Lock mode to
avoid unnecessary charges (e.g. phone calls, web access and data communications).
To wake up your phone, press the
Power/Lock Key
. The Lock screen will
appear. Touch and slide the Lock screen in any direction to unlock the screen. The last
screen you viewed will open.
