Yep, I'm using a Pixel 2 with both DroidCamX and DroidCam OBS (with OBS' virtual camera), I can second that claim.
I occasionally use a Nexus 6 on another setup, but it's a bit bulkier to mount and is a bit finicky with DroidCamX. It has froze up on me a couple times. The OBS version works fine, though. I'll chalk it up to not cleaning up the phone prior to repurposing it.
For those with no camera, DroidCamX works rather well too!
