unlocking it.

• P IN: Enter a PIN with at least four numbers to unlock the screen.
• P assword: Enter a password with at least four characters, numbers, or symbols to unlock
the screen.
• N one: Do not set a screen lock method.
You can set your device to perform a factory data reset if you enter the unlock code
incorrectly several times in a row and reach the attempt limit. Launch the Settings
app, tap Lock screen → Secure lock settings, unlock the screen using the preset
screen lock method, and then tap the Auto factory reset switch to activate it.
