Android phones use Surface Flinger, which is a compositor that has nothing to do with either Wayland or X11. But we could say it’s kinda similar to Wayland in the fact that it’s composited and uses something similar to GBM and GEMM for managing buffers.
Android drivers don’t even use the same “semantics” as Linux drivers (android uses explicit sync, while Linux is implicit, but they are working on supporting explicit sync because Nvidia and because it’s better). It’s only in the last few years that you can use Linux drivers in android, plus some synchronization stuff.
Surface flinger code has some X11 code, I didn’t say it ran X11, I said it just had some of it’s base, GBM and GEMM have been only appeared in the new versions of Surface flinger.
Theoretically many phones use a edited X11.
Obviously that’s not true… like, at all…
