Why can the Xiaomi 14T Pro be unlocked by other fingerprints?

If the Xiaomi 14T Pro can be unlocked by other fingerprints, it's essential to investigate the settings and features that can be contributing to this issue. First, please check whether you have enabled both face recognition and Bluetooth unlock options. When either the face or Bluetooth recognition is successful, a checkmark appears at the top of the screen, allowing access to the home screen simply by pressing the fingerprint area. It’s important to note that this method is not utilizing the fingerprint unlock feature itself. To resolve this issue, it is recommended to turn off the face unlock option and delete any registered Bluetooth unlock credentials. After making these adjustments, please try re-entering to ensure that the device correctly recognizes only the authorized fingerprints. This should help restore the intended functionality of the fingerprint unlock feature and enhance your overall using experience.
