Why is the fingerprint unlock on the Redmi Note 13 Pro not sensitive?

Thank you for your support of Xiaomi products. A fingerprint sensor that is dirty or covered with oils, dust, or residue will not accurately read fingerprints. If the fingerprint sensor or your fingers are wet or sweaty, it can affect sensitivity. If the sensor itself is damaged or malfunctioning, it will not respond correctly to fingerprint inputs. Please ensure that your fingers and the surface of the phone are clean during the unlocking process and you place your finger fully on the sensor and hold it steady until the phone unlocks. It is recommended to use official protective film, as unofficial ones will affect the performance of the fingerprint unlock.
