Dual-Screen Kyocera Echo: Hands On

By Sascha Segan/PCMag

The dual-screen Kyocera Echo smartphone for Sprint lets you do two things at once, or look at the world through a 4.7-inch window. But it’s only the vanguard of a legion of dual-screen devices that may be coming to American shelves, Sprint and Kyocera said today.

First, the phone itself: the Echo is a crazy device, but it thinks the way a lot of us do. It multitasks. The Echo starts out as a standard touch-screen Android 2.2 phone, and it works fine like that. But then you slide the 3.5-inch, 800-by-480 LCD screen, it does a strange hingey thing, and pow: the screen almost merges with another screen hidden under it. (Look at the slideshow below to understand.)

The Echo’s unique hinge is made out of “liquid metal,” Sprint’s vice president for device operations Fared Adib said. It felt like plastic to me, but he said it was metal – and when tested, it was stiff and strong. The phone can survive a seven-foot drop test, he said.

You can use the dual screens a few different ways. By default, the phone is like a mini-tablet with a 4.7-inch, 800-by-960 screen. That’s a nonstandard Android resolution, so some third-party apps may run with a black border. That’s also the least impressive mode; the black bezel in the middle, while very narrow, does get in the way a bit.

Some apps use the two screens for different things. For instance, when playing The Sims, the bottom screen is the control pad, just like on a Nintendo DS. The bottom screen also becomes an uncommonly large touch keyboard (or even a Swype keyboard) when necessary. Typing on the large touch keyboard, with its subtle force feedback, was unusually nice for a touch keyboard.

But the use that really excites me is when you do two totally different things on the two screens. A handful of built-in apps work this way: you can surf a Web page while writing an e-mail, for instance, or pick a photo and toss it to Facebook, or mess with your YouTube queue while watching YouTube.

For obsessive Web browsers and social networkers, I love this phone. Most people multitask on their desktops – I hardly know anyone who keeps one tab open in a Web browser. The Echo lets you flip between different tabs and tasks much more easily than on a non-multitasking phone.

I’m a little concerned about performance. I didn’t see any visible problems in my 20-minute hands-on, but the Echo is running a single-core, 1-GHz Qualcomm QSD8255 processor. That chip, running Android, typically handles one application at a time, not two. The Echo is also pushing more pixels than any Android smartphone, or even than the Samsung Galaxy Tab, with the same class of GPU.

Battery life may also be an issue; with both the screens running full blast, you may not get a whole day’s worth of use. So Sprint is including a second 1370 mAh battery, with its own charger that attaches to the phone’s power cord. You can charge both batteries at once that way. The retail box also includes an 8GB MicroSD memory card.

The Echo will cost $199 when it comes out this spring, Sprint said.
