Update: I went back to another Best Buy to test another Note 8 demo unit and can confirm: I was able to unlock the Note 8 demo with different Facebook profile pics and Instagram selfies from my iPhone as well.

"Whatever, that's just a demo."

You see, that's actually the problem. I see three possibilities:

• The Note 8's facial recognition tech is actually good and Samsung made a crappy demo…But why would anyone do that?
• The Note 8's facial recognition tech is bad and they faked the demo intentionally, just like how Samsung faked performance benchmarks in the past.
• The Note 8's facial recognition tech is bad and the demo is proof of that.

Which is it?
