After you’ve set up and enabled Guest mode, lock the screen, then
press the Home Key to re-display the Lock screen.
Enter your Guest mode pattern. The Guest mode Home screen is displayed
with only the apps you’ve selected for guest access. To exit Guest
mode, simply access the Lock screen again and enter your normal unlock
pattern.
The Guest mode switch is automatically turned off if your lock sequence is changed from Pattern. Otherwise, manually disable it if you no longer want to allow guest access.
