Description

Checks
  • I have read the FAQ section, searched the open issues, and still think this is a new bug.
Describe the bug you encountered:

Since the last 1.12-r5 version installed from the beta program on play store, when I enable biometric full unlock for my database the app sometime forget to use the key file and the fingerprint unlock then fails.
I then have to select again the key file and enter my password.
I'm on a Pixel 7 with Android 15.

No response

Research direction

Start by reproducing the biometric full-unlock flow with a database that uses a key file on Android 15 and version 1.12-r5. Review closed pull request #2901 and its discussion for prior investigation; the issue is done when biometric unlock reliably retains and uses the selected key file without requiring it to be selected again.
