The About dialog of Nexus 3 as well as the system information in support only shows the version and the edition. This is maybe enough for production and installations at customer.
For filing bugs and using internal snapshot versions and maybe also for customers it would be useful to have more details information.
E.g. build date, links to CI server build, git rev of repo and others might be useful to be able to tell in more detail what 3.0.0-SNAPSHOT version you are really using and in turn help developers fixing any issues found.
