Changing Lock Screen Security
Setting up a lock on your device will help keep your information secure. A screen lock will prevent others from getting into your device unless they have the necessary credentials. If your device is requesting a PUK code, you need to contact your carrier to unlock your device. Removing your security lock will allow anyone the ability to unlock your device.
