It seems to be incredibly easy to fool the Samsung Galaxy S8's iris scanner

Back in April, the company behind the Galaxy S8's iris scanning technology claimed it was safer than the FBI's fingerprinting technology. While that may be true, it's still not secure enough to deter a determined thief or hacker.
I've contacted Samsung about the trick, but haven't yet received any comment or official statement.
