I have not tried it myself, but I know for a fact that there are lots of people streaming games they play on their smartphones, if that's what you meant.

This is the help section link about streaming from an Android Phone:

And here's one for iOS:

Sorry if you didn't mean game streaming, my knowledge here is limited. As I said, I have never tried streaming from my smartphone, but these are the guides available on the official DLive Help section.

I'm patiently waiting for that day too, my friend!
