Fingerprint enrollment problem

[askreddy2]

Hi guys,

Recently, I have installed Arrow OS 9.0 and I was unable to enroll my fingerprint (But I can use my fp sensor as home button).

Currently I have flashed stock ROM and restored IMEI. I was able to use both my SIM slots and device name shows xt1643. Again, I was not able to enroll my fingerprint. The error message reads "INTERNAL ERROR, Sorry your fingerprint can not be enrolled due to internal error". But, after rooting my device i was able to use it as home button.

Is there any thing that i have missed? Or is my fp sensor gone?

I am using Redmi Note 4 and facing same problem after flashing Aosp Extended Pie ....The fingerprint sensor wouldn't just work. As if it is dead
Tried deleting these files
Root/data/system/users/0/settings_fingerprint.xml
And
Root/data/system/users/0/fpdata/users.db

Now the files are gone and sensor is dead ....Works when Miui is flashed but dont know what is going wrong in custom Rom

Thankyou brother for the info. But even after reverting back to stock rom, my fp sensor was not working properly. Maybe some of my vendor files were messed up.
