Microsoft's Post-Windows Phone Vision Leaks, But Don't Get Your Hopes Up

While Microsoft's Windows Phone ambitions are well and truly dead at this point, there was a time when the company was plotting a follow-up to the ill-fated mobile operating system. That follow-up was known internally as Andromeda OS, and it was being developed as the operating system for the Surface Duo. Sadly, Microsoft's plan to create a version of Windows for dual-screen devices never saw the light of day, but today we're getting a look at an internal build of Andromeda OS and what could have been.

That look comes from Zac Bowden at Windows Central, who managed to get a build of Andromeda OS up and running on a Lumia 950. Even though Andromeda OS was intended for the Surface Duo, Microsoft apparently conducted internal testing on Lumia 950 devices, making it a solid choice for this hands-on.

In both his write-up and the video you see embedded below, Bowden is very clear that this is not some leak of a work-in-progress mobile operating system. Andromeda OS is dead and not in active development, so there's no real hope of seeing a more fully-featured version launch on Microsoft's mobile hardware at any point in the future. Despite that rather grim reality, this is a good look at the progress Microsoft made before it ultimately decided to ship the Surface Duo with Android.

Though the hands-on shows us an operating system that is very rough-around-the-edges and somewhat clunky, it's immediately obvious that Microsoft planned Andromeda OS with inking capabilities at the center. For instance, the lock screen doubles as an inking space, allowing users to jot quick notes down on it that persist until they're erased or the lock screen is cleared entirely.

Just as well, unlocking the device takes you to a home screen that also doubles as a journal. As with the lock screen, you can use this page to take notes, but you can also do things like paste stuff from the clipboard or insert an image for markup. Having the phone unlock to what is essentially a blank canvas instead of a home screen full of app icons is an interesting idea and one that we're probably never going to see on other devices.

Andromeda OS also features a Start menu reminiscent of Windows Phone, which means that it has those familiar Live Tiles. Bowden also shows off the various gesture controls included in Andromeda OS, swiping from the left to summon the aforementioned Start menu and from the right to bring up Cortana and notifications. Swiping down pulls up the Control Center, which will look familiar to those who are currently using Windows 11.

We're also given a brief demo of what Andromeda OS might have looked like on an actual dual-screen device, but since that demo is also on a Lumia 950, we sadly don't get the full experience. Still, it's interesting to see what might have been before Microsoft decided to can Andromeda OS entirely and switch to Android for the Surface Duo.

While there's no chance we'll see this project revived for future Microsoft hardware, there is always the chance that some individual features could make their way to the Surface Duo. Even then, it's probably best to appreciate this as a relic of the past rather than something that might inform Microsoft's future efforts, as disappointing as that may be for those who miss Windows Phone and Windows 10 Mobile.
