With news Microsoft was working on a ROM for a handset that was known only as an Android phone, ears perked. A few “power users”, in cooperation with Xiaomi, were given the opportunity to check out a Windows build for the Mi 4. One report cited the Windows-for-Xiaomi build as being used to take the place of Android on handsets. Now, Xiaomi boss Hugo Barra is clarifying what Xiaomi and Microsoft are up to. While he didn’t quite refute any prior claims, he did set the record straight.
