    Screen lock

    Arrow left Xperia C4 support overview
    There are several screen lock options available. 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 Home screen.
    • 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.

    Note

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

    Tip

    If you have set up a Microsoft® Exchange ActiveSync® (EAS) account on your Xperia™ device, the EAS security settings may limit the lock screen type to only a PIN or password. This occurs when your network administrator specifies a specific lock screen type for all EAS accounts for security reasons. Contact the network administrator of your company or organisation to check what network security policies are in effect for mobile devices.
