Taiwan-based Wistron Corporation has introduced a mammoth Windows Phone at Computex 2014. It's called the Wistron Tiger Windows Phone.Touted as the world's largest Windows Phone smartphone, it's a phablet of sorts with a 6.45-inch Full HD screen. The display even has a 1,080 x 1,920-pixel resolution. Other noteworthy specs include a quad-core Snapdragon 800 processor and an aluminum build.That said, Wistron's high-end device is only a reference design. It doesn't have any navigation buttons or a camera button. Another manufacturer will therefore have to build upon the reference design in order to bring a final product to marketplace.Browse the gallery below for a closer look at the Wistron Tiger Windows Phone.
