Samsung 2022 Secret Codes For All Android Smartphones Working and Tested

Do you know the USSD codes? What about “Samsung Android secret codes”? These are characters to type on your phone to access information, do tests, or access hidden menus. Let’s see what it is and how to use it.
Let’s start by explaining what is USSD (Unstructured Supplementary Service Data). It is a protocol that allows information to be sent across the network. It is for example possible to recharge your phone with call credit in certain countries. Thanks to this protocol, we buy a card, scratch and enter the code.
In the same way, there are some codes that we can use to access information, do tests, or access hidden menus on our Android phones. Some codes will refuse to work on certain models or brands of smartphones, but you can try them carefully. You could lose data or damage your device. Do the manipulations only if you are absolutely sure of yourself …
To enter these codes just pull up the default dialer app and use your chubby fingers to press the correct buttons.
