More importantly: a cell phone's flash can never be significantly off-axis or diffuse. Flat and/or hard lighting is often worse than no lighting.

I bet you could get an off-camera flash to trigger off a cell phone's flash though.

Couldn’t you rig up a mirror to point the flash at the ceiling?

Seems simpler to buy a slave flash that's triggered by the burst of light.

I did a bit of googling and it seems it's a bit more complex than I realized (sync issues), but can be done.
