Android phones have several master codes, also known as USSD codes. The "secret code to unlock phone" is a unique code provided by the phone manufacturer, allowing users to remove the existing screen lock PIN, pattern, or password, and create a new screen lock type.

No. There isn't a universal master code to unlock any phone. Typically, the master codes are manufacturer-specific, so they might not work on all devices and models. Phone PINs, patterns, and passwords are designed to be unique to each device. A single master code to unlock any phone without password would undermine phone security, creating a huge vulnerability for all smartphone users.
Please note that not all Android devices have master codes to unlock the device. Some older phones, particularly early Android versions, might respond to a master code that enables unlocking phone through a factory reset if you have forgotten password, PIN, or pattern. Similarly, Apple users who wants to unlock iPhone without password will be asked to restore the phone to factory defaults, too.
