Why does the Redmi A5 have delay of fingerprint prompt when adding fingerprint at the same position?

Thank you for supporting Redmi products.
If the phone has delay of fingerprint prompt when adding fingerprint at the same position, please refer to the following details:
1. During the fingerprint registration process, repeatedly placing your finger on the same exact spot is not considered a valid input and is instead interpreted by the system as a timeout or failed attempt;
2. This phenomenon will give you the impression that the system prompt is delayed or unresponsive. In reality, each successful fingerprint capture during the setup process is accompanied by a short vibration, indicating recognition;
3. If there is no vibration feedback, it means the fingerprint was not successfully registered. To ensure proper setup, slightly adjust your finger position each time you touch the sensor.
