What android clients are these ? (i.e. what applications are
you running). Android doesn't ship with a native libsmbclient
so they are either using jCIFS, libsmbclient or a third party
smb client.

As you're getting good speeds from your other (desktop?)
clients then I'm inclined to look into the client lib used
by the apps on android.
