Training Touch ID in the Settings Menu

Hey everyone, I've inferred that you can train Touch ID from the settings menu, I posted this on r/Apple but no one believed me, so I made a video demonstrating it and thought I'd share it here as well:

Great for training more of your finger (I get about halfway down my index finger here) and for those who are having issues with Touch ID not recognizing them.

Long video so you can see the whole process if you wish, important parts if you want to skip around:
:20 - Initial finger alignment / rejection by Touch ID (crease close to bottom edge of screen, I say it's in the middle of the sensor but that's how it appear from my viewing angle)
:43 - Scanning from the tip of my finger, 'normal' area where I initially registered it, moving my finger up to test scanning in the middle of the finger again
5:50 - Same alignment now working

Happy Scanning!
