Samsung Galaxy Secret Codes: The Complete List (And Which Ones to Avoid)


 I was scrolling through a random forum thread late one night when I noticed something odd — people were typing strange little sequences into their dial pad, like *#0*#, and suddenly their whole screen turned into a diagnostic menu. No app, no download, just numbers and symbols hidden inside the phone dialer itself.

Turns out, every Samsung Galaxy phone has a small library of these hidden codes built in — most of them completely harmless, made for testing hardware or checking device info. But a few of them are the digital equivalent of a do not touch sign. Mix them up, and you could wipe your phone by accident.

Here's the full breakdown: what each code does, how to use them safely, and which ones you should genuinely stay away from.

How to Use These Codes

  • Open your phone's regular dialer app (the one you use to make calls)
  • Type the code exactly as shown, including all the * and # symbols
  • You do not need to press the green call button — most codes trigger automatically the moment you type the final #
  • If nothing happens, your carrier may have disabled that specific code, or your model may not support it

Safe & Useful Samsung Codes

These are the codes worth bookmarking. They're built for checking your phone's health, not changing anything permanently.

  • *#0*# — Hardware Test Menu. Opens a full diagnostic suite to test your screen, cameras, vibration motor, speakers, and sensors, all in one place.
  • *#0228# — Battery Status. Shows your exact battery voltage, temperature, and overall health — useful if your battery has been draining faster than usual, especially after a recent update.
  • *#06# — IMEI Checker. Displays your device's unique IMEI number(s), which you'll need if you ever need to report a lost or stolen phone.
  • *#07# — SAR Radiation Info. Shows your phone's SAR (radiation exposure) levels, for anyone curious about that side of device safety.
  • ##002# — Disable Call Forwarding. Instantly turns off all call forwarding — a good quick check if you're worried about a forwarding scam or just want to confirm your calls are going nowhere but to you.

⚠️ Codes You Should Avoid (Unless You Really Know What You're Doing)

This is the part I want to be very direct about, because getting this wrong can genuinely cost you your data.

A couple of codes floating around online aren't diagnostic tools at all — they're factory reset triggers. On some Galaxy models, typing them doesn't ask are you sure? first. It just wipes.

  • Hard reset codes that reinstall factory firmware and erase your internal storage completely
  • Soft reset codes that remove your Google account, settings, and every downloaded app

I'm intentionally not listing these two out digit-by-digit here, and I'd genuinely encourage you not to go hunting for them either. If you don't have a specific, confirmed reason to need a factory reset, there's no upside to having these memorized — only risk.


If your phone actually needs a deep reset or hardware-level fix 

 Say, it's stuck in a bootloop, running painfully slow after a failed update, or you suspect a hardware fault — your safest move is to back up everything first, then either use Samsung's official Settings > General Management > Reset menu, or take it to an authorized Samsung service center. A technician can diagnose the real issue without gambling with a code that might do more damage than good.

Frequently Asked Questions

Q. 1: Do these codes work on every Samsung Galaxy model?

Most of them, yes — they're built into Samsung's dialer system rather than a specific app. That said, very old models or heavily carrier-locked phones may block a few, especially *#0*#.

Q. 2: Will typing a code void my warranty?

No. The safe codes listed here only display information or run built-in tests — they don't change your phone's software or settings, so your warranty stays intact.

Q. 3: Why didn't you list the reset codes directly?

On purpose. A couple of Samsung's hidden codes trigger an instant factory reset with no confirmation prompt, and typing one by accident is an easy way to lose everything on your phone. If you ever genuinely need a factory reset, Samsung's own Settings menu — or a technician — is the safer route.

Q. 4: What's the difference between *#0*# and *#06#?

*#0*# opens a full hardware test menu (screen, camera, sensors). *#06# just shows your IMEI number — it doesn't test anything, it's purely an identifier and checking it is one small part of keeping your phone secure overall.

Final Thoughts

Your Galaxy is quietly carrying a whole diagnostic toolkit you never knew about — no app store required. Used the right way, these codes can save you a trip to a service center for something as simple as checking your battery health or confirming your IMEI. Just remember: the moment a code claims to reset or wipe something, that's your cue to slow down, back up your data, and let Samsung's official tools — or a trained technician — handle it instead.

How to Increase FPS on Android and Mobile Games (No Root Needed)

Image
You're mid-match, everything's on the line — and your game chugs. The screen stutters, your character lags a half-second behind your thumb, and just like that, the round's gone. Sound familiar? Low FPS is one of the most common complaints Android gamers deal with, and the frustrating part is most people assume they need a new phone to fix it. They don't. A few small changes — no root required — can make your games run noticeably smoother. What Even Is FPS? FPS means "frames per second." The higher the number, the smoother your game looks and feels. Most games run best at 60 FPS. If your phone is dropping below that, things start to look like a slideshow — and that's frustrating, especially mid-match. 1. Turn On Game Mode (If Your Phone Has It) Many Android phones — like Samsung, Xiaomi, Realme, and others — come with a built-in Game Mode or Game Booster. Go to your Settings and search for "Game Mode" or "Game Booster." Turn it on. It bl...

Android Privacy Settings You Need to Change Right Now (2026)

Image
You unlock your phone, and somewhere in the background, an old flashlight app you installed two years ago is quietly checking your microphone permissions. You'd never notice — most people don't. That's the uncomfortable truth about Android privacy in 2026: your phone knows far more about you than you realize, and most of that access was granted by accident, not intention. It's not just paranoia. Location history, voice activity, camera access, contact lists — a surprising number of apps request permissions they don't actually need to function. The good news is Android has gotten much better at giving you visibility and control, if you know where to look. If you've ever wanted to keep certain apps private from prying eyes too, our guide on how to hide apps on Android pairs well with these privacy settings. 1 . Why Android Privacy Settings Matter Many apps ask for permissions that are not really needed. Some apps request access to your camera, microphone, contact...

Your phone buzzes, someone asks to see a photo, and you hand it over without thinking — then remember, half a second too late, exactly what app is sitting right there on your home screen.

It stays fully installed and working — it just disappears from view. Let's go through the four easiest ways to do it, whether you're on Samsung , Xiaomi , or stock Android.

And Android makes it pretty easy. If privacy is your main reason, pairing this with your ...

Can You Blog from Your Phone? 5 Real Challenges of Mobile Blogging (And How to Fix Them)

Mobile blogging sounds like a dream — write from anywhere, publish anytime, straight from your smartphone. But if you've actually tried it, you know the reality hits different, especially as a beginner. I know because I lived it. I started my blog entirely on my Android phone, used AI tools to help generate articles, and still felt like something wasn't clicking. Then I hit a wall with Google Search Console and page indexing — a wall I had no idea how to handle from a small screen. That one issue put my entire blog on hold for weeks. So can a beginner really blog from a smartphone? Yes — but only if you know the real challenges nobody talks about. In this article, I'm sharing exactly what those challenges are, the fixes that actually worked for me, and what I wish I'd known on day one. 1.
