In early October 2017, we expected Google to reveal a new operating system that has been rumored and reported for almost two years: ‘Google Andromeda,’ a merging of its Android and Chrome operating systems (OS) in a way we've never before seen. Sadly, that didn’t happen, and today we know that project as ‘Google Fuchsia,’ which is very much still in the works – and publicly.

Fuchsia is expected to become Google’s singular platform for laptops, phones and tablets running its software.
