Hmm I've thought further about this, I don't think there is a way without spending a few bucks. You would need to install side sync on both devices and have wifi on. Trouble is you are not going to be able to run sidesync on s3 without direct access. However, you can get this installed and running if you use a mouse and OTG cable.
