Cannot add new fingerprint

[deadhanuman]

I have xiaomi 13 ultra which runs on miui 14.0.20.0. recently i changed my broken LCD. I had fingerprint lock on the device before changing the LCD. Screen change was good but when i placed my finger to unlock the device it was not unlocking. Then I remove the fingerprint from the settings to add the new one but when i try to add light is glowing on the sensor but not accepting the fingerprint. Then i entered the CIT mode to verify that the fingerprint sensor is working but on that i am getting CALI test - FALSE rest all tests are PASS. Can anyone guide how to fix this. I hope I need to reset the fingerprint sensor data stored on the system. If yes how to do that???

hey i have the same problem on a 13 pro, the seller i got it from sold me this phone for way under its asking price but with a replaced screen,but i cannot get my fingerprints to work

would having them calibrate the sensor fix it?

edit: yea it got fixed

i'm not technician but i think the replaced screen could be aftermarket and it just don't have option of finger print detector (that's my theory at least)
