On Firebase Crashlytics I have a few cases with this error:

Android versions:

• 5.1.1

Devices:

• Galaxy Grand Prime

Expected Behavior

I'm not sure.

Other Technical Details

• "capacitor-native-biometric": "^4.1.3"

Code Reproduction

I'm using:

NativeBiometric.isAvailable()

and

NativeBiometric .verifyIdentity(options)

Both without the useFallback flag. Maybe should I enable this flag? I don't know if this can solve the issue.
