During the fingerprint registration and input process on the POCO C71, if the same area of the finger is repeatedly placed on the sensor, the system does not recognize it as a valid new fingerprint sample. Instead, it treats the repeated input as a timeout or invalid entry, which can create the perception that the input prompt is responding slowly.
Here is more information about the issue:
1. In reality, every time the fingerprint is successfully captured during the input process, the device will produce a vibration feedback. If there is no vibration after touching the sensor, it means the current fingerprint input was invalid;
2. This behavior is part of the design to ensure that complete and diverse fingerprint data is collected for better unlocking accuracy.
