Google has announced that they are now also supporting site names for subdomains on mobile devices. This was after it was added to the domain level for desktop searches last month.

Website structure data
Website owners can indicate their preferred site name by adding the website structure data. The site name documentation shows guidelines on how to set this up for your site.
Google has also provided some common issues encountered with site names in the search results:
Last month, Google posted a webform where site owners can provide feedback about their site names and issues encountered in the search results. This is after a number of people have reported that Google is displaying the wrong site name.
While a number of people have seen improvements and changes after Google has rolled out a change that aimed to resolve the issue, there are still some that reported the issue still existed. To deal with this and any issues encountered with site names, Google has opened up a forum where questions and issues encountered can be reported to the team. This can be accessed here.
