The default Lock screen is Swipe which protects against unintentional
touchscreen actions. Press the Power/Lock Key or the Home Key
to illuminate
the touchscreen if it timed-out. The Swipe 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 and use
the Notifications Panel without unlocking the screen. In addition,
you can also quickly access four shortcut apps (the Phone app
, the Messaging app
, the Email app
, and the Camera app
) without unlocking the screen first. Simply swipe an icon
upward to open and use it.
