Why is my mobile device not recognizing my fingerprint or face ID?

1. Check the settings of your device and ensure that the lock feature is enabled.
2. Check if the power settings of your device are optimal i.e. increased storage consumption can lead to instability.
3. Clean the area where you position your fingerprint or face ID with a clean, dry cloth.
4. Make sure your finger or face is not pressing on any other surface while registering your print or face.
5. Ensure that your finger or face is fully registered so that the device can recognize it.
6. Turn off your device and turn it on again to restart.
