Samsung’s New Jumbo Phone Unlocks with Iris Scanner

You'll be able to unlock Samsung's new phone by just looking at it. The Galaxy Note 7 will come with an iris scanner that matches patterns in your eyes with what was detected by your phone during setup. It offers an alternative to fingerprint ID, which doesn't work well when fingers are wet. Of course, the four-digit passcode will still work.

"We challenged our engineers to design a security system that's convenient and safe at the same time," said Justin Denison, a senior vice president for product strategy at Samsung. "It took five years to perfect, but it only takes a glance to unlock your phone."

Samsung isn't first, though. Microsoft's Lumia 950 phones had it.

Beyond that, the updates in the Note 7 are mostly enhancements, such as a stronger glass screen and more storage -- 64 gigabytes, or double what Samsung usually offers, plus a slot to add more.

The Note 7 comes with a better camera -- but it's the same one that the smaller Galaxy S7 phones got in March, save for interface enhancements to access settings and switch between the front and rear cameras more easily.

Samsung had lost its mojo after Apple matched the company on size with the iPhone 6 and 6 Plus in 2014, but thanks to the popularity of the S7, Samsung just reported its best quarterly financial results in two years. The new Note 7 phone comes weeks before Apple is expected to announce new models.

Samsung typically releases its regular-size phones in the spring and jumbo phones in August. This time, Samsung has just one large model, which stays at 5.7 inches. It will have curved edges -- a well-liked feature limited to a special "Edge" model before. The Note 7 will be available in the U.S. starting Aug. 19. Prices haven't been announced.
