What are service codes Android 4.0

I think that all Android devices are fraught with useful information, which contains information about the system itself and technical characteristics that are hidden from the ordinary user. It is quite difficult for an ordinary user to get to this information, for this you need to look for special Android service codes, which, in turn, are responsible for a specific function of the device.

For example, in Android, using the service codes, you can find out the IMEI (unique device identifier), which you need to know in case of theft of the device in order to block or find it, and much more.

Also, with the help of these very codes, you can quickly open the functions that are deep in the menu of the device, simply by typing it in the dialer.
