Fingerprint sensor not working after LCD replacement

[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.

So the fingerprint is defective. What's the question?

Thanks for the reply. Sensor is working fine. My existing fingerprint data or the driver might be the reason. How to reset the driver for fingerprint which will resolve this issue. Some files from the stock rom will do it. But what are those files. Can you guide me on this. I dont want to reset or flash again the whole rom.

You should ask Xiaomi engineers. No one here has any experience with that.
