Double Screened Phones

No one's really excited by a slide-out keyboard anymore, but you'd be surprised about much attention Sprint's Echo is getting for it's double-screen feature.

At first glance, the Kyocera Echo from Sprint looks like a normal Android touch-screen smartphone—although a chunky one. But a special hinge allows the Echo's top screen to shift up, over and snap down beside a second screen hidden beneath. The two screens correspond with each other to create what looks like one large screen, but one that also allows a different app to run on each screen, or display two activities from the same app on each screen.

The seven apps that can run in what Kyocera calls Simul-Task Mode—a different app on each screen—include email, Web browsing, contacts, gallery, phone, messaging and VueQue—a way of showing YouTube videos on one screen and a queue of upcoming videos on the other. For Simul-Task, users must simultaneously tap a finger on each screen, which displays a menu on both screens showing the seven apps. Each screen will run the app that's selected on it.
