Service (they are engineering, they are also 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 available only for certain device models.

Not so long ago I published an article in which I told how to increase the sound volume on Android. To do this, you could use special software or use one of the secret codes. Now I will talk about the most popular of them, thanks to which you can carry out 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 the instructions for smartphones. First of all, “secret codes” are intended for engineers and developers to conduct various tests.

To use any of the service codes, you need to enter it in the dialer. You’ll have to download a third-party application for making calls on tablets. enter “Dialer” in the Google Play search and download your favorite “dialer”.
