Do you really want Linux phones?

What's that looking like? I'm aware of Anbox but IIRC that runs a full Android runtime and I've seen mixed reports of it working.

Personally I've been kicking around the idea of an API compatibility layer for Android, so an Android app could be built as a standard Java jar and run on top of OpenJDK. I'm not concerned with binary APK compatibility, but there are many apps on F-Droid that I would like to run on non-Android Linux, perhaps without the baggage of something like Anbox. I don't know what it would entail, if there is any interest, or if it's even possible though.
