01Read-Only vs Configuration Codes
Secret codes in Mobile Secret Codes are divided into distinct categories:
- Read-Only Informational Codes: (e.g.
*#06#for IMEI, firmware query, battery temperature). These codes simply display hardware metrics without making any changes. They are 100% safe. - Diagnostic Test Menus: (e.g. LCD RGB test, vibration test, touch screen grid test). These codes open interactive hardware test screens. Exiting the screen returns your phone to normal operation.
- Advanced Engineering / Reset Commands: Certain manufacturer codes are meant for authorized service technicians (e.g., custom ROM wiping, camera firmware flashing). These codes are clearly highlighted with warning notices inside the App.
02Carrier & Manufacturer Variations
Mobile carriers (AT&T, Verizon, T-Mobile, Vodafone, etc.) and device manufacturers frequently customize, restrict, or disable secret dialer codes. Therefore, a code that executes successfully on an international unlocked model may produce an "Invalid MMI code" or "Connection problem" message on carrier-branded firmware.
03No Responsibility for User Actions
Codeink Technologies provides this collection purely as a reference utility. You are solely responsible for executing any code on your personal device. We strongly recommend backing up personal data prior to executing any advanced configuration commands.
