To prepare and calibrate the iPhone in the store requires a special machine. Now a picture of the device found on the Internet, writes Motherboard.

The machine's primary function is to replace cracked screens and calibrate the phone after that. But the new version seems to have more features than previous models, which also leaked online, the last time in 2013.

Among other things, it should be more free-range and industrial in its design. A thick chassis protects the example sensitive calibration components. And in addition to switch screens, can also be used to replace Touch ID buttons. To do this, coupled it with a Mac and sends data to Apple's servers to validate the new sensor – no third-party repair shops do not have access to.
