Getting to know 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 your Home screen. The last
screen you viewed will open.
