unauthorized access. If a screen lock has been set, the screen locks when your phone's display goes to

sleep.

To adjust your phone's lock settings:

1 From a Home or All Apps screen, touch the Settings icon .

2 Touch Personal > Security > Screen lock.

3 Touch the type of lock you want and follow the onscreen instructions.

If you have previously set a lock, you must enter the pattern, PIN, or password to unlock the lock settings.
