How to

Turning use of phone lock code on my mobile phone on or off

If you want to prevent others from accessing the contents of your mobile phone (such as pictures and messages), you need to turn on the phone lock code. Once done, it needs to be keyed in when you turn on your mobile phone. The phone lock code doesn't protect your mobile phone against unauthorised use. Your SIM is protected by turning on your PIN.

Slide your finger down the display starting from the top edge of your mobile phone.
Tap ALL SETTINGS.

Tap lock screen.

Choose one of the following options:
Turn on use of phone lock code, go to 2a.
Turn off use of phone lock code, go to 2b.

Tap the indicator next to "Pasword" until the function is turned on.
Key in the required phone lock code.

Tap the field below "Confirm password" and key in the phone lock code.

Tap done to confirm.

Tap the indicator next to "Pasword" until the function is turned off.
Enter the phone lock code to confirm.

Tap the home icon to return to the home screen.
