Note7 iris scanner not quite ready for prime time (video)

The iris scanner in Samsung's Galaxy Note7 smartphone is a breakthrough in mobile biometric authentication. Unfortunately, it's also not reliable.

Samsung's impressive new Galaxy Note7 smartphone is a genuine tech-spec powerhouse.

Across the board, the Note7's hardware is top of the line. Its large display is glorious, for example. It comes with 64GB of built-in storage — and it supports microSD memory cards. The phone is made with premium materials, such as Corning Gorilla Glass and steel. The Note S Pen stylus has never felt more like a real ballpoint pen. Despite the thin, trim design, the Note7 packs a good-size 3,500-mAh battery. It's also water resistant and relatively light at just 169g.

All this luxury doesn't come cheap. But, hey, you have to pay if you want the best the world's leading Android-phone maker has to offer.

In addition to all these bulked-up specs, the Note7 showcases some true innovation in authentication. The new iris camera and dedicated infrared LED let Note7 users unlock their phones with a glimpse at the iris scanner.

I spent the past week with the Note7 and purposefully put the iris scanner through a number of tests. Unfortunately, I found the new biometric authentication feature to be more than a little … finicky. Check out the video above for specifics on why.
