Many Nokia smartphones that run the Android system have a special test menu in which the hardware can be put through its paces.
So you can test for example the camera, the screen, the speakers and other hardware.
However, this menu cannot be called directly from the Android interface. This means that you must open the test menu using a special method described below.
Note that not all Nokia smartphones have such a test menu, or it has been disabled by your company's manufacturer or system administrator.
