I ask because I've worked on various products, and single units change hands between engineers constantly. Phones for testing, accounts with shared dev passwords, the actual hardware, all kinds of test units get spun up and passed around, even on crappy products where the engineers' imaginations are the only QA.

Surely one engineer set up a camera, passed it along to another engineer, who set up the camera and encountered this error?

There are lots of classes of error that can hide in a product, but this feels like one that it's nearly impossible not to hit.
