Face recognition is not working on Samsung A34 devices.

Face recognition is not working on Samsung A34 devices.

The library does not detect that the device has only configured the face recognition option.

A call to BiometricAuthenticationService.Default.GetAuthenticationStatusAsync() returns NotEnrolled when Face recognition is the only option configured on the device.

Work well with Fingerprint.

What happens when you call AuthenticateAsync without GetAuthenticationStatusAsync when you just have FACE enrolled?

I didn't tested because first I need to know if some auth method is configured then call authenticateasync. This flow works with Fingerprint configured but not with face recognition in Android...

Like I said don't authenticate if it exists or not directly try authenticating and see if that works. The native dependencies that we have for the plugin don't support this by default and hence I cannot do anything for information check the pinned issue

@emilio-wstcopilot Any updates?

Hello there, I'm experiencing the same problem with Android 13 and Android 14. Everything works with Android 15 and iOS in general.

• ⛓️‍💥 OPPO Find X3 Neo 5G Color OS 13.1 (Android 13)
• ⛓️‍💥 Samsung S22 (Android 14)
• 🔗 Google Pixel 9 (Android 15)

CASE 1 - Reproducible error in Android 13/14

• [x] Facial recognition is the only option configured.
• ⛓️‍💥 AuthenticateAsync returns a AuthenticationResponse object with the following error message: "Authentication failed, please try again later, error code:11 Nessuna impronta digitale registrata." It seems that the plugin is looking for the configured fingerprint because the italian sentence "Nessuna impronta digitale registrata" means "No fingerprints recorded"
• ⛓️‍💥 GetAuthenticationStatusAsync returns Plugin.Maui.Biometric.BiometricHwStatus.NotEnrolled
• ⛓️‍💥 GetEnrolledBiometricTypesAsync returns an enumerable collation wirth Plugin.Maui.Biometric.BiometricType.Face and Plugin.Maui.Biometric.BiometricType.Fingerprint

CASE 2

• [x] Facial recognition and Fingerprint are both configured in the system.
• 🔗 AuthenticateAsync checks for the Fingerprint recognition.
• 🔗 GetAuthenticationStatusAsync returns Plugin.Maui.Biometric.BiometricHwStatus.Success
• 🔗 GetEnrolledBiometricTypesAsync returns an enumerable collation wirth Plugin.Maui.Biometric.BiometricType.Face and Plugin.Maui.Biometric.BiometricType.Fingerprint

@kayne87 I will try to check this the next time i get a chance, the unfortunate thing is I don't have a lot of Android devices, I will try my best though
