Guess How This 7-Year-Old Broke Into His Dad's iPhone?

When it comes to kids and smartphones, they know how to use 'em better than many adults.

Exhibit A:

For background, Matthew Green teaches cryptography at Johns Hopkins University and is a privacy expert. But clearly, he couldn't outsmart his 7-year-old son who just wanted to play some games on his iPhone 6 Plus and snuck into his parents' room, grabbed his dad's thumb, and pressed it on the fingerprint detector.

So to those who think the iPhone encryption is indestructible or a threat to the law: think again.
