Network Discovery of Android Devices [closed]

I've used nmap extensively and while I've found it's in general pretty good at discovering the OS on server and desktop/laptop hardware it's pretty poor at detecting embedded and handheld kernels.

This is because quite frequently these systems are not listening on any ports, and it's the responses to TCP handshake process that gives the most OS detection information.

Without an open port all nmap has to work on is the response to closed ports and ICMP echo replies.
