Why can someone else’s fingerprint unlock my Xiaomi phone?
If your Xiaomi phone is being unlocked by someone else’s fingerprint, please refer to the following information:
1. Check if face recognition or Bluetooth unlock is enabled. Someone else can enter the home screen when these succeed. Disable face and Bluetooth unlock, then delete and re-register your fingerprints.
2. Check if fingerprints are not registered properly. Delete all fingerprints, then carefully re-register them from multiple angles.
3. Check if dirt, moisture, or a screen protector is interfering with the sensor. Clean the sensor and your finger, remove any covering, and re-register the fingerprint.
4. Please update your system to the latest version and check if the issue is resolved.
5. If none of the above solutions work, please contact the after-sales service center for further assistance.
