Biometric unlock broken

[technodrome]

Describe the bug Biometric unlock on 1.25.1 does not work. On app startup, I always have to log in using password. When I head to settings and try to enable BU there, modal with fingerprint scan pops up and I can scan my finger. Then the pill button briefly shows BU enabled but then immediately switches back to disabled BU state.

To Reproduce Steps to reproduce the behavior:

1. Open app, enter password (cannot use BU)
2. Click on Settings, try to enable BU, scan, shows BU enabled for a moment, then switches automatically back to BU disabled

Error Failed to store cipher appears in log:

Expected behavior Working BU.

Hi,

Thanks for the detailed report. Can you try clearing and setting the app password before enabling biometric unlock?

Cheers

After doing that, the app is completely broken. I cannot even start it, it completely crashes with the following SQLite error which repeats upon every app start.

Had to uninstall the app, reinstall and restore from backup. Lost all the settings. Upon fresh install, app works without SQLite or biometric unlock issues. Could be caused by version upgrade but it is definitely not user-friendly or smooth experience.

@jamie-mh I'll leave it up to you to close this if you do not want to investigate.

It works for me using 1.25.1.

OS: One UI 6.0, based of Android 14 (Samsung)

For the sake of helping this issue, I tried it on my Android 11 based custom OS. Works fine.

However, I just installed this app and didn't add any entries yet. Maybe some older update broke something earlier, which becomes only visible in rare scenarios?

At least, the following strongly suggests, this is the case.

Upon fresh install, app works without SQLite or biometric unlock issues.

@jamie-mh

Maybe add a warning to an FAQ or the README, so people are aware of such an issue, when upgrading from older versions? 🙂
