Thank you for your support of Xiaomi products. The Redmi Note 13 Pro 5G has undergone strict professional inspection before leaving the factory, so you can use it with confidence.
For this issue, you can refer to the following information:
1. It is recommended to keep your fingers and the surface of the phone clean when unlocking;
2. Delete the existing fingerprint information and re-enter it according to the phone prompts. Make sure to cover different parts of the fingerprint when recording, especially the edges and fingertips;
3. Try to use official films. Unofficial films such as anti-peep films and anti-blue light films will have a certain impact on fingerprint performance;
4. Update the phone system to the latest version and try again.
If the above methods are not effective, please apply to the after-sales service for inspection and repair.
