Press the Power/Lock Key to
illuminate the touchscreen if it has timed-out. If the unlock sequence
is set to Swipe, a default Lock screen is displayed,
but you can still conveniently check the date, time, and Status Bar
icons. You can drag the Status Bar down to open the Notifications
Panel without unlocking the screen. In addition, you can also quickly
access four applications (the Phone application,
the Email application, the Camera application, and the Messaging application)
without fully unlocking the screen. Simply swipe the icon upward to
open and use it.
