Authentication does not work on non-fingerprint old devices (Don't mind Spanish, I have Spanish on school :( )

[ian1ilych]

Description

So my device is good up and running until it the app says that it took too long on authentication and so i realized this app needs a fingerprint, and my device dosen't had it.

Reproduction steps

1. Install the app on an old or older device running Android 9.0 or older
2. Sign in or Up with that device
3. Unlock the vault and Wait a few seconds or more, and done

Hi Ian, thanks for reporting this. We're investigating the issue and will get back to you.

Hey, I tried adding a biometric hardware check. Can you test this branch and tell me if you still face this issue?

It still has it.

Maybe try changing the behaviour of biometrics if it detects that it has fingerprint on your device, if it does not have it, then it will cancel and instead access normally and bypassing it.

There's no way that can be done, since it goes against our security model of binding the Keyring to Keystore+BiometricPrompt (reference). I need to look into other fixes.

Interestingly enough, I tested this on a Moto G XT1033 from 2013 with an Android Pie Custom Rom and it worked just fine.

So the reason why it didn't worked is because i have an official operating system called the old One UI 1.1 and you used a custom operating system with ROM.

So it didn't worked, make sure it reads the model of the phone and its operating system (from most official brands), make sure it reads what brand made the model and the most important thing, what biometric supports

Im ian1ilych and basically:
The app had an issue where my device dosen't support fingerprints and the app needs it so im stuck with that image at the beginning.
