Service (secret) codes for Android smartphones

Android secret codes

Service (they are also engineering, they are secret) codes are used for quick access to various functions, often even hidden. There are universal codes for Android, and there are those that are only available for certain device models.

Now I will talk about the most popular of them, thanks to which you can implement many system settings.

Popular secret codes for Android smartphones

Why are these codes called “secret”? Simply, they are not needed by most ordinary users, they are not published in instructions to smartphones. First of all, “secret codes” are intended for engineers and developers for conducting various tests.

To use any of the service codes, you need to enter it in the dialer. On the tablets you will have to download a third-party application for making calls – enter the query “Dialer” in the Google Play search and load the “caller” you like.

Android Service Codes in Secret Codes

The Secret Codes application will scan the system for engineering codes and display the result in a list. You just need to click on the code of interest and you will go to the desired option.

Unfortunately, this method has a minus: on some devices, the application does not find a single service code, and on some finds not all. But on the devices, I tested everything was fine, and the reviews on Google Play are almost all positive.
