Targeting Android via Standalone and Client. Reproduced on a Samsung Galaxy S10+, with the latest version of the Expo Client installed (v2.15.0).

Steps to Reproduce

1. Start/Upgrade a Project with SDK37
2. Call LocalAuthentication.authenticateAsync()

Expected Behavior

Android Authentication UI should appear on top of the screen that is currently requests Authentication.

Regular Android Authentication

Actual Behavior

Android Authentication UI appears in a separate screen before the user is navigated back to their original screen.

SDK37 LocalAuthentication

Reproducible Demo

I have created a reproducible Snack demo here. I can also confirm that this problem is exhibited when a standalone app has been built in SDK37.

Interestingly, the UI appears correctly when using the Android simulator on the Snack. However running the Snack on my Samsung S10+ I can reproduce the unexpected behaviour, and my friend is also able to reproduce similar behaviour on his One Plus 7 Pro.

EDIT: I managed to get a hold of a Pixel 4, and the UI does appear correctly on this device. It's possible it's a "Custom" UI issue?

Any news on this? Its not something urgent, but we are thinking about implementing this at my company, would be nice to have this working

I can also see that UI appears in weird way. Since latest version of Localauthentication uses BiometricPrompt on Android, I think it should show system ui for biometric authentication like the photo below.

On Samsung device with Android 10, Expo also shows the system biometric authentication ui. But in a bit weird way. Whether test it on expo client or standalone build, It shows the dialog on the seperate black empty screen.

And it seems like it only happens on Samsung device with Android 10. I tested the snack on Appetize.io with Android 10. And it showed the prompt properly.

Seems like this is potentially an issue with Google blacklisting some of the major Samsung flagships. However there must be a solution as every Native app I use on the S10+ can display the Biometric Popup correctly.
