Mangosmiley159 Fingerprints work fine. Are you trying to enroll them in the Owner profile, or a secondary profile?
It's probably best to open a new thread about this though, in the interest of keeping each discussion focused on a specific thing.
If this is an option for you, I'd flash Stock OS on your device and try the screen recording to see if it works. If it doesn't, we can safely assume it's something with your hardware. If it works, we can look further into it.
