What is DRParser?

DRParser mode is a hidden app on your Samsung smartphone that takes in special codes using which you can test hardware features, enable or disable them and even see important system information.

The app has the package name and can only be accessed by typing the following code in your calculator.

Entering the code will launch DRParser Mode.

As soon as you’ll finish typing the code, your calculator will switch to DRParser Mode and you’ll see a numpad with * and # buttons. From here on, you can enter different codes to access different modes for debugging problems, testing hardware, viewing information and so on.
