comes with four Nokia-exclusive applications not included by the default Windows Phone OS: Nokia Drive, a free turn-by-turn navigation system; Nokia Maps; Nokia Music, a free streaming music service and music store; and App Highlights, a service suggesting software based on location and operator. In addition to these applications and services, Microsoft added Office 365, in which the user can edit documents, create spreadsheets, open PowerPoint presentations, and even make OneNote files. The files created can be stored on Microsoft's SkyDrive cloud service, on the phone itself, and other areas. Nokia Collection In addition to pre-installed Nokia-exclusive Windows Phone applications, the Windows Phone Marketplace contains a Nokia Collection section. As of April 2012, it contains the following additional applications: Nokia Transport, a location-aware public transport schedule and navigation application; Creative Studio, a photo editing application; TuneIn Radio, a local and global radio streaming application; CNN, a news reader and video viewer for the Cable News Network; and WRC Live, an application to follow live timing and media from the FIA WRC series. Diagnostic Tool Just like the Lumia 900, the 800 comes with a diagnostic tool. It can be accessed by pressing ##634# on the dial keypad, which should initiate the download after the last # is pressed. The diagnostic tool should appear on the app list under Diagnostics.

It's also possible to perform all the tests in one run. The application is intended to be used by device engineers to run tests to find whether a certain component is working properly. The app is uninstallable.
