Although we've been hands-on with a very early and fragile prototype, the physical improvements are immediately obvious. When you turn the phone over to its "normal" side, for example to watch video or use the camera, you'll notice that the 720p LCD panel has been upgraded to a slightly bigger 5-inch, 1080p, AMOLED one.
Android performance will also benefit from the inclusion of a 2.3GHz
Snapdragon 800 instead of the old Snapdragon 600, and overall thickness has been reduced to 8.9mm (0.35 inches). Assuming that the price doesn't soar much higher than the original's 499 ($675), these are all very welcome changes.
