Since android 10 and its desktop mode would be nice to have virtual displays there as well. On rooted phones it shouldn't be hard to get such a driver into a kernel. Android distros like LineageOS would be probably more than happy to incorporate such a solution. Another thing is Linux, drivers for virtual screen already exist, check xvfb and xorg-video-dummy
