SECRET CODES · ANDROID TOOLS
Welcome to
Secret Codes
One place for hidden dial codes.
Tap a code, open menus, learn what your phone is actually doing.
Secret Codes collects useful Android dial codes (USSD / service codes) that can open device info, tests, and manufacturer menus that don’t sit in the usual settings.
No clutter, no “tutorial quest”. Just codes, grouped and ready to use, so you don’t have to memorize anything.
What you can do
- Browse categorized secret dial codes
- Tap to dial (fast access to hidden menus)
- Copy or share codes (including WhatsApp)
- Discover device info & basic hardware tests
- Keep everything in one clean, simple UI
Heads-up:
Some codes can change settings or trigger diagnostics. Use only what you understand.
If a code isn’t supported by your manufacturer, it may do nothing.
