Droid Secret Codes

Store and manage your USSD & Android Secret Codes — and run built-in hardware tests on your phone.

[ No Root Needed ]

AndroidCodes keeps your secret/USSD code list in one place and now adds a full set of native device tests, so you can check your hardware even on modern Android versions where many older codes no longer work.

SECRET / USSD CODES

- Browse a built-in list of Android secret codes and USSD codes

- Open codes in your phone dialer (operator/network USSD codes are processed and called)

- Add, edit, delete, search and sort your own codes

- Import, export, back up and share your code list with other devices or people

- Save your favorite codes for quick access

HARDWARE TOOLS (no codes required, work on current Android)

- Device Information: model, Android version, security patch, RAM, storage, CPU

- Battery Health and live Charging / Current (mA & watts)

- Sensor Test, Spirit Level, Compass, Proximity, Light (lux)

- Screen / Dead-Pixel test, Scratch Identifier, Touch and Multi-touch tests

- Vibration and Flashlight / LED tests

- Speaker, Microphone, Earpiece, and Headphone / USB-C audio tests

- GPS test (fix, accuracy, satellites)

- Hardware Buttons test

- Full Hardware Test: run every check in one guided pass

ABOUT PERMISSIONS

- Microphone is used only for the live microphone test

- Location is used only for the GPS test (foreground only)

- These are never collected or shared

KEEP IN MIND

- Secret/USSD codes can change some device settings — use them carefully.

- Some manufacturers, Android versions, or dialers may not run certain codes

(many codes require the stock phone dialer, and Android 10+ disabled several

older codes). The hardware tools above work regardless.
