New [mi6] Miui 9 Fingerprint Sensor Not Working Fine

[_HxC_]

Hi,
open this thread because on miui forum just passed 3 weeks that the status is WORKIN ON IT but miui devs
can not fix this problem as you will see later on by the videos.
The fingerprint sensor has become slow and does not recognize fingers immediately when the device it's locked especially on surfaces flat like tables.
I've alredy try to reflash several times from miui 9 to the last miui 8 and 7.7.20 everything worked fine.
Reflashing to miui 9 bug reappears.
Reflashing to miui 8 bug disappears.
Here belows two videos before and after which confirm what I said.
I hope that somebody can campare values of fingerprint between miui8 and miui9.
Many thanks for your patiance reading this post.

Miui 8 7.7.20 WORKS!!!!

The fingerprint scanner was working as expected until today after I run the Hardware test in the Kernel. When I try to unlock the phone with my finger it work really rarely and only when my finger is 90 degrees.
How did you solve the problem?
