Still, I'm more into Windows 10 Mobile then into Android.
We could go even further with ideas, such as projecting the screen to a TV! Thanks for sharing this with us, this is really interesting! Though from this video one would think that this is more unpractical than it actually is, because one could actually get a bluetooth mouse and connect it to their phone, or if possible - to a phablet! A bluetooth keyboard could be helpful for this matter too.
