What problem are you trying to solve? Technically yes, you could create a package containing a file containing the model name and then assign that to devices with Model as a Filter Criteria. I'm more curious why you would actually need this information in a file on the device when the model information is already reported to SOTI by the agent. 

EDIT

I see now that you're actually talking about the Device Name and not Model Name, so my original suggestion would not be particularly helpful. I'm still curious about the use case however. There was a new feature introduced in 14.4 to let you use Device Name with Filter Criteria. 

Let me be a bit more specific.

I'm wondering if the MobiControl DeviceName is written in any file on the device? I know I can put a file including the devicename on the device using package or filesync but that's not the point. I want to read the the DN using an app.

On Windows CE device I would just send out a textfile and a postscript that replacesany text with %MCDEVICENAME% or read it from the pdb.ini file but that doesn't work on Android.
