Answer a few quick questions to evaluate your visit.

Screen lock

When the screen is locked, you have to unlock it with a swipe gesture or with your personal pattern, PIN, password,. Initially, the unprotected screen swipe is set, but it is recommended to use a more secure screen lock to protect your device.

The security level of each lock type is listed below in order of weakest to strongest:
  • Swipe – no protection, but you have quick access to the Homescreen.
  • Pattern – draw a simple pattern with your finger to unlock your device.
  • PIN – enter a numeric PIN of at least four digits to unlock your device.
  • Password – enter an alpha-numeric password to unlock your device.

To configure the notifications on the lockscreen, see Notifications.

To create or change a screen lock

It is very important that you remember your screen lock when using a pattern, PIN, or password. If you forget this information, it may not be possible to restore important data, such as contacts and messages. See troubleshooting tips .

  1. Find and tap Settings > Lock screen & security > Screen lock.
  2. If requested, confirm your current screen lock.
  3. Choose an option and follow the on-screen instructions.
  4. When a secure screen lock is used, you can set the power button to lock the screen, set the screen lock activation time, and create a lock screen message by pressing Settings icon.

If you use a Microsoft Exchange ActiveSync (EAS) account, the EAS security settings may limit the lockscreen type to only a PIN or password. Contact your network administrator to check the implemented network security policies.
