The kernel is not the operating system, even if it is a key component of it. Android phones do use the Linux kernel - well, not exactly; some kind of modified version of it - but they do not use the GNU/Linux operating system. The OS is different in many ways: Filesystem hierarchy, daemons/services, graphics stack, etc.
