Looks like things are about to get real and about to get messy. At least as far as Google and Microsoft are concerned. It's no secret that Microsoft is going to provide a way for Xiaomi Mi 4 owners to wipe Android off their device and install a preview of Windows 10 for phones instead. And while there a few caveats to that story, it does practically mean that Microsoft is trying to take a nibble out of Google's pie in China. Now just a few weeks later, this video appears showing that exact setup, and the result might give Google reason to worry.
