The FxTec is still a closed Android blob driver device as far as I can see. As long as that is true we are pretty much screwed on getting a real GNU-Linux backend including x11 UI onto the device especially since a converged Linux-Android Linux kernel seems to have gone the way of fusion for power and true AI; far in the future with no good plan to get there.

I get by with LineageOS for microG though even my Nexus 7 just got EOL'ed by LineageOS so the microG also has ended updates; because drivers.
