Why is the light of fingerprint unlocking on the Xiaomi 14T so bright?

The bright fingerprint light during unlocking is designed to provide light to help illuminate the fingerprint sensor, making it easier to capture your fingerprint accurately, indicate whether the sensor is active, whether a scan is successful, or if there’s an error and ensuring performance in various scenarios and enhance the overall experience by providing visual cues during the unlocking process, helping you know when to place their finger.
You can try enabling the low light fingerprint unlock feature in the fingerprint settings, however, this will increase the unlock time. We are continuously monitoring this issue and are working on improvements to enhance your experience. Thank you for your understanding and support.
