First dual-screen mobile phone
Kyocera Echo smart phone
8.9 centimetre(s)
Europe ()
Instead of one large an unwieldy 11.9-cm (4.7-in) smart phone screen, the Kyocera Echo smart phone is equipped with twin 8.9-cm (3.5-in) displays with a hinge in the middle so when closed, the phone is no larger than a regular touch slab-style screen smart phone. Each screen can run a different application or display a different web page, or a single app can be run or a single web page can be displayed across both screens; one screen can also display a QWERTY keyboard. Echo runs Android 2.2 and is powered by a 1-GHz processor.
