[OPPO A12] Fingerprint scanner not working

[olsdf]

Current Behavior:

I can't set up the scanner, just nothing happens on the screen

Describe the bug

I found out something here, it turns out that the scanner works, and even if you somehow force it to function in the system, you can register your finger.
But due to the fact that [email protected] is not compatible with this model, instead of launching the scanner the following happens:

I was chatting with one user from the 4PDA forum and after he read my logs, he sent me a line with the content [email protected]
and points out to me that the scanner is not working because of this. For a long time we tried to understand what the reason was. I even removed this component from the system, but then I lost the ability to configure the scanner.
I tried many methods that would help me finally set up the scanner, but to no avail.
After the scanner cannot initialize itself, it enters the gesture navigation mode and therefore the scanner starts working. On Android 12 the situation is more interesting - after I try to configure the scanner, a window pops up with an error that the scanner could not be configured.
Although there are no errors at all on Android 10 and I already understand why. Because it initialized itself as “gesture navigation”, so no errors appear on the screen, and on Android 12 it doesn’t work that way.

To Reproduce

1. Go to 'Settings'
2. Click on 'Secutiry'
3. Scroll down to 'Fingerprint'
4. See error

Expected behavior

The scanner would have continued to be set up and I would have completed it successfully
