MY fingerprint sensor stoped working after an official screen replacement

[het donga]

MY fingerprint sensor stopped working after an official screen replacement by samsung
reason for screen replacement; my screen went white after using it for 2-3 years thus i had to pay for replacement as my warranty got expired.
note; my father used it for a year or so but he did not use finger print to unlock his phone
after he gave it to me i discovered this issue.

@het donga: I'm sorry to hear that you have experienced this issue. For clarity, was the Fingerprint sensor working as expected prior to sending the phone for the screen replacement? Also, do you get any error messages or notifications when setting up the Fingerprint biometric, or is it simply unresponsive?

yes, before my screen got blank my fingerprint sensor was working
firstly when ever i try to add my finger print by
 1 Go to “Settings”.
2 Tap “Biometrics and security”.
3 Tap “Fingerprints”.
4Enter your PIN, pattern or password.
it will gust freez there, 
it takes a lot of time to think and many of the times it even shows this message setting isn't responding, close app or wait.
secondly, when i press *#0*# and then on sensor
it just shows NA when i press normal scan and for the sensor info it is just a blank white page.
