The model of the device (Read Only).
Exact format of model name is operating system dependent, for example iOS device names typically look
like "iPhone6,1", whereas Android device names are often in "manufacturer model" format
(e.g. "LGE Nexus 5" or "SAMSUNG-SM-G900A"). The returned model can also be a very generic name
(e.g. "PC") if the actual model name is not available or relevant on the current platform.
