Are you familiar with the USSD codes What about the “Android secret code”? These characters can be used to unlock information, perform tests, or access hidden menus. Let’s find out what it is and how it can be used.
Some secret codes are Android system codes. They usually start with an asterisk “*”. Because they are only for your Android system, you don’t need to connect to a network in order to use them.
These codes are regularly updated as new versions of Android software become available. Some manufacturers also have additional codes.
It is easy to enter code. All you have to do is bring up your dialer keypad and then enter the correct number sequence.
You should note that some codes can only be used on certain carriers. If your phone does not respond to the code, you can simply move on to another one.
Attention! These codes should not be used without caution. These codes can cause your phone to lose data or make it unusable. You may find a lot of tech jargon in the menus that you don’t understand.
Let’s begin by explaining what USSD is. It’s a protocol that allows information across the network. For example, you can recharge your phone with call credit in certain countries. This protocol allows us to buy a card and then scratch the code.
The same goes for Android phones. There are codes we can use to access information and hidden menus.
You can test them on specific models and brands of smartphones but some codes may not work. Your device could be damaged or lose data. Only perform manipulations if you’re 100% sure.
