The default Lock screen

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 (Phone, Messaging, Search, and Camera) without fully unlocking the screen. Simply swipe the icon upward to open and use it.
