Hidden Diagnostic app on Lumia 800
The kind folks over at “The Nokia Blog” seem to have found a hidden easter egg (or is it Turkey Egg considering it’s thanksgivings?) on the Lumia 800, the hidden app is a Diagnostics tool that runs a check on most sensors, buttons, speakers and touchpanels of the 800 to make sure everything is in tip-top shape. Activating it is as simple as opening your Dialer and dialing ‘##634#’ upon which a app called “Diagnostics” will show up in your app list, rather than read this watch the video
List of whats diagnosed:
Accelerometer
ALS
Audio Loopback
Bluetooth
Camera
Battery Status

The correct name is “On-Device Diagnostic Tool” (short: ODDT) and it’s available to Windows Phone 7 in general – including Samsung, HTC, etc.
A full description of the diagnostic menu/tests can be found here (in german):

I noticed an issue when using this tool on my 800, it would be useful if someone else could try to reproduce this.
Go to the hardware buttons page
Press a couple of the hardware buttons to ensure that they work correctly.
Press the back button
Try the hardware buttons
What I found here was that my hardware buttons no longer worked. I didn’t actually find this out until after my display had turned off and the only way I could bring it back to life was to plug the charger in.
If you go into the Hardware Buttons page again and press the ‘Main Menu’ option in the top left, the buttons should work again (this sometimes hangs the diagnostics tool, but pressing Home brings everything back to life).
If this is actually an issue, it seems like a worrying one to have when you can’t remove the battery!
