I paid 40k for a 10k phone.It has worst biometrics ever seen.Like too slow and the face unlock doesn't even detect.I would have gone oneplus 7t which is way better and smoother but due to this indo china thing i went for samsung.
Bro sadly these under display fingerprint aren't even close to Capacitive Fingerprint scanners, You can try a few tips Like Registering fingerprint twice.
And also I couldn't get the link for the article but you can Google the tricks to increase the performance of Ultrasonic fingerprint scanner and hope that will help.
Please perform the below mentioned steps to resolve the issue:
* To improve recognition performance, register fingerprints of the hand used most often to perform tasks on the device.
