While all android phones technically use a linux kernel, they have
nothing else in common with a normal Linux system. Android has it's
own libc: bionic. It also has special IPC mechanisms enabled in the
linux kernel, and it uses gralloc instead of fbdev or DRM. I think
gralloc is the biggest problem with android phones, it's absolutely
useless for everything except for androids SurfaceFlinger and
canonicals Mir.

I Really hope the Librem 5 will get fbdev support, so I can see boot
messages on a framebuffer console, and optionally DRM support for
things like OpenGL and Vulkan.
