The problem with a customized device is that only you
know what was done to it.

If Samba was working correctly then your smb.conf
setup looks fine.

You'll have to debug this by using debug level 10
logs and examining where the write isn't getting
done.

Android isn't (yet) a supported platform for
Samba as unrooted devices don't allow applications
to bind to low ports.
