This is my setup: Android tablets runing kitkat and a Otg cable plus SSH Client app from play store.

It works fine if you can live with that horrible soft keyboard, and i think this might be useful if you need to make some minor tweaks to your bbb when runing in a remote place and you dont have your laptop with you.

I managed to edit, compile and load a new device tree overlay with this setup, but damm that keyboard is hard to live with.
