There are four icons in the center of your lock screen that you can use for quick access to the Phone application, the Messaging application, the Google application, and the Camera application. Tap and drag any of these icons upwards to immediately open and use its application. There’s no need to unlock the screen or tap any other keys.
This is the default Lock Screen. If you've set up an Unlock Pattern, use your fingertip to draw the pattern.
Different clock themes can be applied to the lock screen.
