Introduced at Computex on Wednesday is the largest screened Windows Phone device, the Wistron Tiger Windows Phone. The 6.45 inch screen features a 1080 x 1920 resolution, a quad-core Snapdragon 800 processor, and an aluminum build. It does lack navigation buttons and a camera button. This is a reference device that will need to be built by a manufacturer, in order to make it to the marketplace.
The 7 inch Android powered Samsung Galaxy W currently is the phone with the largest screen, followed by the Wistron Tiger Windows Phone. The ZTE Nubia X6
and the Sony Xperia Z Ultra
both are next, each with a 6.44 inch screen.
