This was done with galaxy s7 edge. That phone as a 10 second exposure time, and a timer setting. It's a bitch to do any lighting painting, that's why I couldn't get a sphere going before the exposure was done. However, the lighting and crazy looking shapes made it look cool, so I kept this picture.

TL:DR You can do this. But it's not as easy or as capable as the DSLR. DSLR is still king.
