Samsung Galaxy devices are known for their powerful hardware, deep customization options, and hidden features that go far beyond the standard user interface. Many of these hidden functions can be accessed through Samsung secret codes, special USSD, and diagnostic codes built into the system for hardware testing, software troubleshooting, and advanced system checks.
Whether you're using the latest Galaxy S25 Ultra, Z Fold7, a budget-friendly Galaxy A series phone, or a Galaxy Tab, these updated 2026 Samsung secret codes can help you test components, diagnose issues, access hidden menus, and better understand how your device works. In this guide, you'll learn what Samsung secret codes are, explore the most useful codes for 2026 models, discover how to use them safely, and find a bonus solution for unlocking a Samsung device without a password.
Samsung secret codes are short numeric or alphanumeric sequences that can be entered directly into the phone's dialer to access hidden system menus, diagnostic tools, and advanced functions. These codes are built into Samsung's firmware and are commonly used for hardware testing, software diagnostics, and system checks.
Unlike many third-party tools, most Samsung secret codes work on unrooted devices, making them accessible to everyday users as well as advanced users. While many codes are safe and read-only, some advanced options can modify system settings or erase data, so it's always recommended to proceed with caution and back up important data beforehand.
Below is a curated list of Samsung secret codes for 2026, organized by use case. These codes may vary depending on device model, One UI version, Android version, region, and carrier restrictions. Some codes may not work on newer Galaxy devices or carrier-locked phones.

Using Samsung secret codes is straightforward and doesn't require technical expertise for basic codes. Follow these steps to safely access hidden menus:
Step 1. Open the Dialer App
Launch the default Phone app on your Samsung device (third-party dialers may not support secret codes).
Step 2. Enter the Secret Code
Type the full code (including asterisks and hashes) into the dial pad. Do not press the call button unless required. Some codes activate automatically after entry, while others may require pressing the call button.
Step 3. Access the Hidden Menu
If the code is compatible with your device, a hidden menu will open immediately. For example, entering *#06# will display your IMEI, while *#0*# opens the hardware test menu.
Step 4. Navigate the Menu
Use the on-screen buttons or volume keys to navigate through the menu (some menus support touch navigation). Follow the on-screen instructions for testing or adjusting settings.
Step 5. Exit Safely
To exit a hidden menu, press the Back or Home button. Avoid force-closing the menu, as it may cause temporary glitches or slowdowns.
If you've forgotten your Samsung device's password or PIN and can't access it, Samsung secret codes won't help with unlocking your screen. In such cases, a reliable tool like Android Unlock can make a big difference. It allows you to unlock your Samsung device without losing any data, even when you forget your password, pattern, or PIN.
