Why did Huawei disappear after 9s fingerprint unlocking?

If you can't find the fingerprint option in the phone settings. You can do the following:

Please upgrade your mobile phone to the latest system version.

Please restart your phone and try again.

If your mobile phone is the latest system version, the problem still exists after trying to restart, which may be a hardware problem. It is recommended that you back up important data and bring the purchase voucher to the nearby Huawei customer service center for testing.
