The image was obtained by Motherboard's Jason Koebler after putting out a bounty. The machine is reportedly kept under constant video surveillance and its full functionality is unknown outside Apple.
"It was a big clunky machine that honestly looked like someone built it in their backyard," a former Apple Genius tells Koebler. "There were different 'moulds' that different iPhone models would go into before going in the machine, and it would take around 30 minutes … there was some weird liquid that needed to be placed in the machine that we would have to wear gloves with to fix it. Lots of gas type valves and whatnot. It literally looked like some backyard home job. Not very Apple-like at all."
The shapes seen on the left in the image below are for calibrating the iPhone's camera. The "flock paper" and "gray card" are for calibrating the iPhone's screen colors. Most importantly, the device lets Apple replace the Touch ID home button, which no third party repair shop can do.
The only other photo of the 'iPhone Calibration Machine' we're aware of was posted back in 2013 and it was taken from much further away.
