To save battery power, your screen goes to sleep if you haven't used it for a while. You can adjust the amount of time before your phone should sleep.

To keep your phone secure, make the screen lock when it goes to sleep:

• Choose from facial recognition, a pattern, PIN, or password to unlock.
• You can make emergency calls on a locked phone. A locked phone still rings; you don't need to unlock it with your PIN or pattern to answer.
• If you forget your pattern, PIN, or password, contact your carrier.

For additional security, you can also encrypt your phone. Encryption protects the accounts, apps, and files so that people cannot access them if your phone is stolen.
