It’s known that Android is a compelling operating system with tons of amazing features and functions. However, many Android users are unaware of the Android Secret Codes, also known as the MMI or USSD codes. These codes are a combination of symbols and numbers that unlock several hidden menus, features, tools, and systems.
Android has a backdoor designed by developers for various purposes. However, you cannot access the hidden menus and features without these secret codes. As beneficial as these codes can be, they can be dangerous if misused. Cybercriminals use these cybercodes for hacking and breaking into servers worldwide.
How to use Android Secret Codes?
Android phones are equipped with Unstructured Supplementary Service Data, also known as USSD, that can help users enable features quicker than usual.
To use the Android Secret Codes, you must open the Phone app, go to the Dial Pad, and enter your desired code. Some codes will help you check your battery, some might help with Wi-Fi, and some might reset your phone altogether. It’s important to know which code you’re using to avoid destruction. On the other hand, not all codes are supported by all Android phones. So, check your codes twice before you use them.
