I mean that I don’t know what part of my comment is “not true”. I welcome corrections, I just don’t see what is being corrected here.

It doesn’t send a yes/no signal it sends the fingerprint to be compared to the stored one

The app gets either the onAuthenticationSucceeded
or onAuthenticationFailed
callback. It doesn’t get the fingerprint.
Edit: I think we are misunderstanding each other, I’m saying that apps never see the fingerprint. The OS does, depending on the device.
