**Describe the bug**

Starting with the newest version, attempting to open a file causes the app to freeze when entering password.

To Reproduce

Steps to reproduce the behavior:

1. Open app
2. Open kbdx file
3. Attempt to enter password
4. App becomes unresponsive

Expected behavior

Should be able to enter password (or read fingerprint)

KeePass Database

• Created with: Tested with a new database created in KeepassDX, and my previously functioning file created in KeepassXC
• Version: 2
• Location: [e.g. Remote file retrieved with GDrive app]
• File provider: tried with both local file and stored in Nextcloud
• Size: Multiple sizes
• Contains attachment: No

KeePassDX:

• Version: 4.0.6
• Build: F-Droid
• Language: English

Android:

• Device: Samsung GalaxyS10e
• Version: 12

Additional context

Add any other context about the problem here.

• Browser for Autofill: Firefox

Saw behavior both with using auto fill, and opening app directly.

Also cleared app data and created new file, and still saw this bug.

Additional information: this seems to only happen if biometric unlocking is enabled, even if it hasn't been set for a particular file.

Also, I mistakenly believed this was only in the latest version, because it was a recent change. However, I tried downgrading and the issue persisted, until I cleared app data and didn't enable biometric unlocking.

So, it seems to be related to a change in that, rather than the app specifically.

This is not a KeePassDX update regression. The problem has been reported on some Samsung devices (specifically on S10). The Keystore on these devices doesn't seem to be handled properly, try to delete a biometric fingerprint and put it back.

Interesting. Thanks for this. I wonder what changed recently that this suddenly became an issue for me when I've been using it for years without problem.

I'll give this a try.

Try to delete a biometric fingerprint and put it back.

Thanks for the suggestion. Unfortunately, that didn't help at all. I tried deleting all my fingerprints, and then putting them back in. Once I re-enabled biometrics in KeepassDX settings, it freezes up.

Bummer that Samsung screwed this up, and I can't use it anymore.

Maybe a reboot is the solution? https://github.com/Kunzisoft/KeePassDX/issues/1269#issuecomment-1115339395

Of course that's it. 😆

Thank you. Working with fingerprint again. If it stops working again in six months, I guess I'll know what to do.
