Nokia Diagnostics

For those of you who want to investigate a little if you are having issues rather than taking your device straight to a store or Care Centre this app is a little gem. OK, it’s no full on diagnostics suite, but it will enable you to run numerous tests on your phone if for no other reason than to tell others when reporting an issue.



The app name is somewhat self explanatory as it is called Nokia Diagnostics and it is intended to help you diagnose issues on your phone. There are two versions of the app, one for Symbian S60v.2 (non-touch) phones and one for Symbian S60v5 and Symbian^3 (touch) phones.

With these different versions comes different functionality with the latter version providing a much more extensive range of tests. The list of tests available on each of the versions is listed below:

S60 3.2 version contains following tests:

  • Network Coverage test
  • Internet connectivity test
  • Battery charger test
  • Loudspeaker
  • Earpiece test

S60 5.0 & Symbian^3 versions contain following tests:

  • Vibrating alert
  • Memory
  • Battery charger
  • Memory card
  • Cameras
  • Keypad
  • Screen
  • USB cable
  • Web browser
  • Network coverage
  • Data coverage
  • GPS
  • Earpiece
  • Microphone
  • Loudspeaker
  • Headset

In addition to the increased number of tests, the S60 5.0 and Symbian^3 versions also provide an  advanced mode and the ability to do a batch run of tests.

I haven’t had need to use this app other than testing it, but it’s a nice little something to have in your mobile back pocket to help diagnose an issue if one occurs.

I should note that some of the titles in the app are a little messed up, displaying the code name rather than the corresponding display names in some cases. For example, when you open the Audio Tests screen, you will see “qtn_diag_title_audio”. In other cases, like the Connectivity Tests screen the title shows as “USB Test”, independent of which ever test you select. I am happy to the Hardware Tests screen shows the correct title.

Another issue I have noted is that on my Nokia N8, at least, the “Ambient Light Sensor” fails. I believe the N8 does have an ambient light sensor for the display, but when you enable advanced mode the test provides an empty folder implying it has done nothing and the results always show as fail.

All this said I do like this little app and always have it installed, just in case. Check it out, along with many other useful apps at Nokia Beta Labs.
