Leak offers a glimpse at Microsoft's canceled Andromeda OS for dual-screen devices

Before Microsoft announced the Surface Duo in 2019, the company spent several years working on an operating system codenamed Andromeda. It was envisioned as a reboot of Windows Phone with an emphasis on inking. The company worked on the software until it eventually decided to instead include Android on the Surface Duo. Until now, we’ve only seen glimpses of Andromeda in things like patent filing. But Windows Central recently obtained an internal build of the operating system and installed it on a Lumia 950.
