It’s actually under heavy developement now and ppl run it on Ubuntu Touch. It’s just for Halium 9 devices. I’m actually hunting some cheap Pixel or OnePlus 3+ to install this. Atm, running Ubuntu Touch as a daily driver on Sony Xperia X and it runs fine. Pretty much everything works, but videocalls are not. WayDroid will solve that and some other small issues and we will have decent MobileOS on Linux side.

That’s absolutely incredible.
