TheDom, yes, but I think his question would/is probably more along the lines of: how do you connect to another device to be able to use said phone screen controls to send commands to the other device?
Honestly, khadembashy, I think there has to be other software that could achieve your idea. Construct 2 is suited specifically more for games.
However, if you are leaning more toward using a phone device to connect with, say, a browser of yours to control the game loaded in said browser, that would be possible using the WebRTC Multiplayer plugin, and I'm already getting ideas for it.
