As we reported earlier, an enthusiastic Nokia fan discovered a hidden diagnostics app in the new Nokia Lumia 800.
Dialing ##634## will launch the diagnostics application which tests the functionality of all the device’s hardware – compass, speakers, camera, accelerometer, LEDs and other functions are tested.
However, this test revealed an interesting fact – the Lumia 800 doesn’t have a hidden gyroscope. On the other hand the digital compass works perfectly. The diagnostics application has just one big minus – it doesn’t give access to the registry.
