Change Android USB Device Name for Windows Explorer
It is just a name for the device that the manufacture put there. Change the name, call it what you like, it does not matter. 

The pop up is part of Windows and will call on the device's real name (what the manufacturer called it). This device name is embedded into the your mobile device and can not be changed without going down to a low level of programming.

In your phone spec on GSMarena, you will notice that your phone has multiple names.
