The fingerprint sensor on my Huawei Mate 20 stopped working, how can I resolve it?

If your Huawei Mate 20's fingerprint sensor has stopped working, various reasons could be to blame.

First, make sure your finger and the sensor area are clean and dry, since moisture or debris can prevent proper recognition.

Also, check to see whether a third-party screen protector is installed; non-standard protectors can interfere with the in-screen optical sensor by decreasing light transmission.

If the issue persists, re-registering your fingerprint may assist. Navigate to **Settings > Biometrics & Password > Fingerprint ID**, erase the existing fingerprint data, and then follow the prompts to create a new fingerprint.

To ensure maximum accuracy, make sure to cover the whole sensor surface during this operation.

Software flaws might potentially cause sensor malfunctions. Restart your device to refresh the system processes.

If the fingerprint option is absent from the settings, it could be a hardware issue or a software fault from a recent update. In this scenario, try performing a factory reset after backing up crucial data.
