The Medias W has two 4.3-inch screens that, when unfolded, combine to create a roughly square 5.6-inch display. The phone runs Android 4.1, and when navigating the OS you have two options for what to do with the extra pixels — double your home screen real estate, or use the second screen as a browser, photo gallery, or app switcher.
The browser works really well across both screens, loading the full desktop versions of websites as well as you'd expect from a tablet, and two-screen Google Maps is another killer feature — how many times have you wanted more screen space when zooming in and out of narrow city streets on your phone?
We also found it a lot easier to type on than most phones, with the keyboard comfortably spanning both screens. All of this is handled well enough by a 1.5GHz dual-core processor, though there was some occasional lag when switching between display configurations.
