Secret Codes: View Phone Info

Every Android phone hides a set of secret dial codes — shortcuts that open hidden diagnostics, signal tests and device info screens. Most of the code lists you find online are copy-pasted junk that does nothing on your handset. Secret Codes: Phone Info is different. It detects your exact model first, then shows you only the codes that actually work on it. MATCHED TO YOUR PHONE, NOT "ANDROID IN GENERAL" Open the app and it reads your model, manufacturer, Android version and SDK level. A Galaxy S24, for example, comes back as SM-S921B, samsung, Android 15, SDK 35. From there the catalogue filters itself: 116 codes for that handset, and 23 known duds hidden. A code that does nothing is worse than no code at all. ONE TAP TO THE DIALER No typing, no typos. Tap a code and we copy it and open your dialer with it loaded, so it lands even on phones whose dialer strips special characters. NOTHING FIRES BY ACCIDENT A few of these codes are destructive — one of them factory-resets certain Samsung devices. Every destructive code is flagged before you tap it and stops for a full confirmation, where Cancel is the default. Nothing reaches your dialer until you decide it should. OR SKIP THE CODE ENTIRELY Where a code has a Settings equivalent, we hand you the exact path, tap by tap. It is usually the safer route, and it always works. CONFIRMED BY PEOPLE WITH YOUR PHONE Owners of the same model confirm which codes work, so you can see what has actually been tested on your handset rather than on someone else's. REAL CODES YOU WILL FIND INSIDE *#*#4636#*#* — phone info, battery and usage statistics *#0*# — hardware test menu: screen, speakers, sensors, vibration *#1234# — firmware and baseband version Plus the full catalogue for your device: network and signal diagnostics, SIM and device identity, display and touch tests, audio and camera checks, and the service menus your manufacturer left in. PRIVATE BY DESIGN No account. No sign-up. No permissions requested. The catalogue works offline. A NOTE ON WHAT THESE CODES ARE Secret codes are diagnostic shortcuts built in by phone manufacturers. Which ones exist depends on your model, your carrier and your Android version. This app tells you which ones apply to yours, warns you about the ones that bite, and gets out of the way.
