I have implemented biometric authentication in my application with biometric level BIOMETRIC_STRONG (Class 3). The fingerprint authentication is working as expected but I couldn't able to test the face authentication on any of my devices (Samsung Galaxy S10, Oppo A3S, etc.). I think the face authentication in those devices is not falling under Class 3.
Are there any Android devices with BIOMETRIC_STRONG (Class 3) face authentication? It would be helpful if someone can provide a list.
Edit: Pixel 8 now has Class 3 face authentication too.
Pixel 4 is currently the only device with face authentication that qualifies as BIOMETRIC_STRONG (Class 3).
Face authentication was not added to pixel 5, and looks like there are no plans to add it back with Pixel 6 either.
This is true as of 5th October 2021, but there might be more devices that support in the future.
