Did you know your Samsung smartphone has a hidden toolbox of features, waiting to be unlocked with a few simple taps on the dialer? These combinations of symbols and numbers, known as Samsung secret codes, allow you to access a world of hidden menus, run detailed diagnostics, and view crucial device information that isn’t available through standard settings.

Whether you’re a tech enthusiast looking to explore your device’s full potential or a user trying to troubleshoot a specific problem, this comprehensive guide will give you the most up-to-date Samsung secret codes for 2025.

Disclaimer: The functionality of these codes can vary depending on your specific Samsung phone model, network carrier, and One UI version. Please use caution with codes labeled “High Risk” and always back up your data before using any reset codes.

What Are Samsung Secret Codes?

These functions are primarily used by developers, repair technicians, and internal staff for testing and diagnostics.

While they may seem like a magical trick, using them is straightforward. Simply open the Phone app, enter the code, and a new screen will appear instantly.

How to Use Samsung Secret Codes Safely

While exploring these codes can be fun and useful, it’s crucial to do so responsibly.

1. Back Up Your Data: Before entering any code, especially those in the “Reset” category, ensure your photos, contacts, and other important data are backed up to Google Drive or Samsung Cloud.

3. Use Reputable Sources: Only use codes from trusted sources like this guide. Avoid random codes found on unknown websites.
