I don’t think Android is linux desktop, even not a linux mobile. Yes indeed, there is so called kernel there, but it wrapped with custom bootloader, custom apis, custom desktop and set of apps developed and managed by single corporation. Android of course inherit some of linux legacy - instability, inefficiency, inflexibility, tivolization. But half-bakeness, because we say so approach and 70s legacy are not there, due to market competition. When the corporation replace linux/drivers firmware blob with their own, Android will remain Android, and not Fuchisa Desktop.
