Android currently stands as the most widely used mobile operating system globally. If you’ve been an Android user for some time, you’re likely familiar with USSD codes, which are input directly into the dialer to execute various functions. Successful entry of these codes prompts automatic responses or requires pressing the “Dial” button. So, what are the prevalent Android security codes, and what functions do these “secret codes” perform?

Categories of Android Security Codes

There are two primary categories of codes applicable to Android phones.

1. MMI (Man Machine Interface) Codes: These are factory-configured by the phone producer and provide access to hidden settings.

2. USSD (Unstructured Supplementary Service Data) Codes: These are simple codes for unlocking hidden actions on your smartphone.
