1. Avoid placing your phone with sharp objects (such as keys) to prevent the surface of the fingerprint unlock part from being cracked, scratched, or worn out.

2. Ensure that the finger you use to unlock the screen is clean. If your finger is stained with alcohol, lotion, sweat, or grease, the accuracy of fingerprint recognition may be decreased. Therefore, clean the surface of the fingerprint sensor in a timely manner.

If this is affecting your use of the phone, please back up your data and then take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
