Enable biometric unlock (settings) about lockwise-android

@nickbrandt , @changecourse
Could you please let me know the expected behaviour for the following scenarios?

1. If the device has no fingerprint sensor, "Unlock with fingerprint" item will be displayed in Settings? Or it will be hidden/disabled?
2. If the device has a fingerprint sensor, but no fingerprint was set yet. Which is the expected behaviour in this case?
3. Which is the default value in Settings for "Unlock with fingerprint"? Will be set in the On Boarding process?
4. What will happen if enabling fingerprint fails for 5 times?

@ioana-farcas here are my thoughts. Also looking to @sandysage and @changecourse for their opinions as well.

1. If the device has no fingerprint sensor, "Unlock with fingerprint" item will be displayed in Settings? Or it will be hidden/disabled?

Do not show Fingerprint option

2. If the device has a fingerprint sensor, but no fingerprint was set yet. Which is the expected behavior in this case?

Either show this in a disabled state (leaning towards this), or show in normal state, but when tapping this option, provide a dialog to the user letting them know they first have to set up a Fingerprint (assuming more work)

3. Which is the default value in Settings for "Unlock with fingerprint"? Will be set in the On Boarding process?

This will be set during onboarding. We are only enabling this after a user has given permission, so if for any reason they skipped or missed this during onboarding, it would be turned off.

4. What will happen if enabling fingerprint fails for 5 times?

Provide the user with the standard error message of "Too many attempts. Try again later.", and return to where the user was. We do not want a fallback for Pattern/PIN/Password when enabling the feature.

Let me know your thoughts or if there are any questions about this!

@ioana-farcas let's proceed with Nick's recommendations, except on question 2.

If the device has a fingerprint sensor, but no fingerprint was set yet. Which is the expected behavior in this case?

@nickbrandt and I chatted briefly on the behavior here. I assume if someone has a device with a fingerprint sensor, and have not set their device to use it, this is intentional. As such, let's not show the Fingerprint option, if not set, and fallback to the pin code.

Do not show Fingerprint option

@changecourse, let's make sure to include a question or 2 around expectation here in our usability testing.
