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.

How to make passcode work on Android?

Secret codes on Android almost all end with a pound sign (#) and in some cases with an asterisk. An important difference between these and USSD codes is that it is not necessary to press the green call button to validate the code.

Just enter the code as if you were about to dial a phone number and if nothing happens, it's not working on your device. Sometimes the codes also depend on the version of Android you are using. These codes also work even when no SIM card is present in the smartphone.

A little warning before we start. It is important to know that some of these codes may change the settings or behavior of your device, format it, or even cause damage.
