Information / Solution
You may experience that the fingerprint sensor on your Xperia 1 doesn’t respond in a satisfactory way.
Please try to register your fingerprint again.
Touch the sensor with your finger at the same area where you unlock the screen with the same gripping way as usual.
You should not move your finger widely regardless of the animation UI.
Tip: For Xperia 1 users, in the software version 55.2.A.4.47, there were implemented some improvements for the fingerprint sensor recognition. Please update the software in your Xperia 1 to version 55.2.A.4.47 or higher and then re-register your fingerprints again.
