Hacker: Secret Codes & Ciphers

What Hacker: Secret Codes & Ciphers does

Hacker: Secret Codes & Ciphers is a reference app for Android users who want quick access to mobile USSD codes, manufacturer codes, hidden settings, and device tips. It brings technical information into one searchable-style collection instead of requiring separate web searches. The app suits curious power users, phone technicians, and anyone troubleshooting a device’s hardware or system behaviour.

Tools and information inside

• Code library: Browse codes associated with different manufacturers and mobile services.
• Diagnostic references: Find options for checking screens, sensors, batteries, and other hardware areas.
• Carrier codes: Look up codes used for tasks such as balance checks and service-related actions.
• Tips and tricks: Review grouped guidance for accessing settings and functions that may not be obvious in a standard Android interface.
• Offline reference: The stored information can remain available when an internet connection is not convenient.

Who may find it useful

This is more of a practical reference shelf than a general entertainment app. It can help when checking a second-hand phone, investigating a suspected hardware problem, or looking for a code tied to a particular handset or carrier. Results depend on the device and network, so a code listed in the app may not work universally. Users should also understand what a code changes before running it.

Scale and standing

Developed by Vidmark Inc., the app sits in the Libraries & Demo category and has reached 5,000,000+ installs. Its rating is 4.33 out of 5 from 22,162 ratings, suggesting sustained interest in its compact collection of Android codes and technical references.
