How To Use Screen Lock Settings – Sony Xperia C3 Dual
Learn how to use screen lock settings on your Sony Xperia C3 Dual. There are several ways to lock the screen. 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
- Face Unlock: unlocks your device when you look at it
- Unlock pattern: draw a simple pattern with your finger to unlock your device
- Unlock PIN: enter a numeric PIN of at least four digits to unlock your device
- Unlock password: enter an alpha-numeric password to unlock your device
