Hacker: Secret Codes & Ciphers
Overview
Secret Codes And Mobile Hacks app is a specialized technical utility developed by Vidmark Inc., designed to provide Android enthusiasts with a comprehensive database of hidden system codes. These codes, often referred to as MMI (Man-Machine Interface), USSD (Unstructured Supplementary Service Data), or "secret" dialer codes, allow users to access hidden diagnostic menus that are typically restricted to technicians and advanced developers. By manually entering these codes into the phone's dialer, users can uncover detailed hardware statistics, such as the IMEI number, firmware version, hardware serial numbers, and specific software versions.
The application is structured as an offline-capable "secrets manual," featuring categorized lists for major manufacturers including Samsung, Xiaomi, Oppo, LG, and Google. Beyond raw codes, the app provides a robust library of "Android Tips and Tricks" that guide users through tasks such as bypassing factory reset protection, managing background process limits, performing LCD/touchscreen checks, and retrieving deleted files. It is marketed as an essential tool for "tech lovers" and professionals who need quick access to system-level diagnostics without requiring root access or special permissions during installation.
From a technical perspective, the app functions as a repository for ciphers that interact directly with the Android OS's telephony and system services. While the name suggests a "hacking" orientation, the developer clarifies that the app is purely informational and safe, provided it is used by experienced individuals who understand the implications of altering system settings. This utility is particularly valuable for users purchasing second-hand devices, as it allows them to quickly verify the authenticity and physical health of the hardware through built-in manufacturer test menus.

How do I execute the secret codes found in the app?
Users must manually transcribe or memorize the code string and then type it directly into their smartphone's standard calling dialer app.
Is this app intended for illegal hacking?
No, the application is an informational utility for accessing built-in diagnostic and system menus that are already present on the device.
Why don't some codes work on my Samsung/Pixel phone?
Manufacturers or network providers often lock certain USSD or MMI codes to prevent accidental system changes by consumers.
Does the app require my phone to be rooted?
No, most secret codes and system tips provided in the application work on standard, non-rooted Android devices.
Can this app help me find my phone's IMEI number?
Yes, the application provides the standard universal codes (like *#06#) and manufacturer-specific strings to retrieve IMEI and serial information.
Hot Reviews
This app is a fantastic resource for tech enthusiasts who want to "deep dive" into their phone’s settings. The IMEI and firmware diagnostic codes are particularly useful for verifying hardware authenticity.
The information provided is top-tier and accurate, but the frequency of advertisements can be frustrating. It's a fair tradeoff for a free app, but a paid "ad-free" version would be a welcome addition.
While the app is billed for everyone, it is truly meant for experienced users. Executing some of these ciphers can alter critical settings or wipe data, so beginners should proceed with caution.
