Android: secret codes to access hidden features

There are a myriad of secret codes on Android that allow access to technical information on the device, to perform specific tests or actions. Several tens or even hundreds of secret codes can be used on Android smartphones or tablets. We take a look at the most important ones.

Android secret codes are not to be confused with USSD (Unstructured Supplementary Service Data) codes that almost everyone uses or has used to interact with their operator's services via GSM networks. Orange, for example, offers around twenty USSD codes to access some of its services. But these codes, unlike secret codes, do not depend on Android or manufacturers, but on operators.

Orange's #123# code, which allows you to track your credit balance, will for example be accessible on any mobile OS. Although there are also universal secret codes like the famous *#06# to know your IMEI number. Enough chatter: here is a list of all secret codes on Android.
