A continuously curated, comprehensive archive of hidden MMI (Man-Machine Interface) and USSD codes for Android devices, including manufacturer-specific diagnostics, hidden service menus, and deep system controls.
The codes listed are primarily MMI codes (processed locally for menus) or Supplementary Service codes (standard call features).
- Manufacturer-Specific Codes: Extensive codes for Samsung, Google Pixel, Xiaomi, LG, and many more (see the full list).
- 🛠️ Hidden Service Codes: Dedicated tools for diagnostics, calibration, and component testing.
- 📡 Network Debugging: Commands for RIL, RF Band selection, modem controls, and location-based services (LBS).
- 📞 Universal MMI Codes: Standard codes for call management, forwarding, and status checks.
The scope has been expanded beyond Samsung to include Google, Xiaomi, LG, and many other manufacturers, aiming for a truly universal resource.
Some codes will reboot your phone, reset network configurations, or access secure hardware menus. Do not execute any code you do not fully understand.
IMPORTANT: Due to firmware, carrier, and model variations, the exact code format required can change. If a code fails, try these variations:
| If Listed As: | Try This Variation: |
