How to troubleshoot and Unlock Biometric feature of Blink App
Choose the OS
Biometric Unlock enables opening of the blink app using the biometric features of your device. Biometric features refers to face ID, fingerprint, or other device-based authentication using some aspect of your physical being.
When Biometric Unlock is active, your device disables the screenshot function. If your device running the Blink app does not have a biometric feature, enabling Biometric Unlock has no result
Biometric authentication is completely handled by the device, outside of the Blink app. While the authentication prompt is being shown, the Blink app is not in control of the user interface.
Some common authentication failure resolutions:
This is correct behavior. The app cannot know it was the same user that closed Blink, opened the other apps or settings screen, then re-opened Blink. To protect your account, Biometric Unlock re-authenticates every time the app is opened
App preview be when the app is in the background
The app preview should be a blue-tinted blur. If the app is running in the foreground, and the App Switcher is opened, then the blink app's preview should be the most-recent screen

No device PIN fallback
Yes, that is as-designed. The regular sign-in process is still available if Biometric Unlock does not work as expected
