Samsung's new jumbo phone unlocks with iris scanner

The Galaxy Note 7 will come with an iris scanner, which matches patterns in your eyes with what was detected by your phone during setup.

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.

Samsung is also releasing an updated virtual-reality headset — with a dedicated home button, a wider field of view and a black interior to improve viewing.

Samsung says Secure Folder stores sensitive documents and even entire apps in a separate, secure location.
