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

- 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)

ABOUT PERMISSIONS
- Microphone is used only for the live microphone test
- Location is used only for the GPS test (foreground only)

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.
