I love hidden diagnostics. Lets you see what they play with and let’s you check to make sure things are operating ok. So if you have a Lumia just type in ##634## and a Diagnostic app will be added to your Lumia.

Accelerometer, ALS, audio loopback, camera, battery status, DTMF, gyroscope, hardware buttons, headset detection, LCD white, lights,life timer, magetometer, power source, proximity, speaker, touch and vibration.

You also have the option to run all the tests in one run

This was found in the AT&T forums from Pham.  Thanks for the tip buddy- we appreciate it.


  1. Err, forget to mention that in my L900 summary. The Diagnostics menu is nice. Can check how quickly for battery is charging/draining for example.

    @Marti: Been trying to find the back door on the Surround for a year. Can get to one menu, but not very informative. The Holy Grail still eludes us. They hid it well.

  2. I’m quite disappointed that Nokia does not allow you to change these settings like you could on the Samsung Focus. Maybe someone will figure out how to do this down the road.
