Cannot use ssh or scp on that server, as it has no /bin/sh (maybe it is
possible to install one, I do not know).  So I tried sftp to see if that
could work, since I can access the Android server with sftp from the
command line and also using the Gnome/Mate remote server access, which I
suppose uses sftp (they call it SSH method).

Just tried (never used it before) and no, it does not work, same
behaviour.  Note that starting with Gpg2 (if I remember correctly) which
used a keyring daemon under X to get the password propmpt, I regularly
kill the keyring daemon, in order to get the password prompt in the
Emacs minibuffer.  That works with gpg mail.  I suspect that Tramp does
something that needs the keyring daemon whe using sftp:.  I use
regularly ssh: or scp: and they work.

Ah, using ssh: on that server works until it tries to execute /bin/sh,
meaning the login does in fact work
