I know about WayDroid, but never heard of ATL.

So yeah, while we have the fundamentals, we still don’t have an OS that’s stable enough as a daily driver on phones.

And this isn’t a Linux issue. It’s mostly because of proprietary drivers. GrapheneOS already has the issue that it only works on Pixel phones.

I can imagine, bringing a Linux only mobile OS to life is even harder. I wish android phones were designed in a way, that there is a driver layer and an OS layer, with standerdized APIs to simply swap the OS layer for any unix-like system.
