Why doesn't the phone wake up when I touch the fingerprint scanner?

If your phone doesn't wake up when you touch the fingerprint scanner, check the following:

• In Settings > Fingerprint scanner, make sure Wake up screen is selected.
• Make sure the proximity sensor is not covered when holding the phone. Refer to the user guide to see where this sensor is located.
• Make sure your finger is not wet or too dry.
• Do not wear gloves when using the fingerprint scanner.
• Touch the fingerprint scanner for at least 2 seconds for it to recognize your fingerprint.
