HTC is said to be dropping a planned big-screen Windows Phone 8 smartphone, which was intended to go toe-to-toe with some of the latest Android devices with large displays, including HTC’s own Droid DNA. The reason HTC scrapped the plan is reportedly a lack of high resolution screen support in Windows Phone 8, according to Bloomberg, since Microsoft’s mobile OS only offers up to 720p resolution, while big-screen devices are mostly now using 1080p or greater.
