The best answer that I have found (from @volo on question 1995439) is to download this CSV file from Google, and find the marketing name corresponding to what Build.MODEL gives you. You could do this dynamically, but this means that you do an Internet query every time the user asks for the marketing name. I think that I prefer to download the the file as part of my build script and stuff it into a resource. However this means that I can only report marketing names that existed last time I built my app.
