Introduction
Nokia Windows phones devices have a "hidden" diagnostic app. This app can be used to confirm that device functionality is present and working as expected, and is particularly useful for verifying whether "odd" results are due to your code or to information from the hardware.
The tools can be accessed for the first time by entering ##634# on the call screen/dialler. Subsequently the app is listed with all your others under the title Diagnostics.
