Key features ¶
Features differentiating Lumia 900 from Lumia 800 are the bigger 4.3" display, a substantially bigger capacity battery, fourth generation network (4G LTE) support, a front-facing second camera, enabling picture from a video call, the lack of included headset and the lack of included rubber bumper case.
The Lumia 900 device 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. 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 Cable News Network content; WRC Live, an application to follow live timing and media from the FIA WRC series.
Diagnostic Tool ¶
Just like the Lumia 800, the 900 has the diagnostic tool.
It can be obtained 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.
On this diagnostic tool a user can run tests on the following: Accelerometer, ALS, audio loopback, camera, battery status, DTMF, gyroscope, hardware buttons, headset detection, LCD white, lights, life timer, magnetometer, power source, proximity, speaker, touch and vibration. It's also possible to perform all the tests in one run.
Note: This app does not harm the phone, it's just a hidden app Nokia forgot to mention in the owner's guide. The app can be uninstalled if a user chooses to do so.
