Samsung Secret/Test Code List and Hidden Functions 2025

Part 1. Understanding Samsung Secret/Test Codes

Samsung secret codes or test codes are unique combinations of numbers and symbols that you enter into your phone's dialer. When keyed in, Samsung codes reveal hidden menu settings or execute internal tests that are otherwise employed by Samsung service technicians or power users only. They are a convenient means to verify hardware functions, software versions, battery conditions, and more—without any additional apps.

Consider these Samsung codes as secret shortcuts. For instance, a single code would open a menu to test your touchscreen, whereas a different code would reveal your phone's battery level or IMEI number. They come in handy when your phone's behaving erratically, overheats, drains battery, or when you simply want to ensure everything's in working condition.

The catch, though, is that not all codes are compatible with all Samsung devices, whether old or new, or all software versions. Some are model-specific, while others are deactivated on some phones. You therefore have to stick to using a correct list where you utilize only codes known to be safe and tested on your phone.

And don't worry—most Samsung test codes do nothing but show you information or access menus. Some codes, though, restore your phone to its factory settings or modify settings, so be sure to read what a code does prior to using it!

Now let's discuss some incredible Samsung secret codes today!

Part 2. Samsung Secret/Test Code List and Hidden Functions

Samsung phones have a range of hidden codes that allow you to access diagnostic tools, get detailed system data, and enable functions not accessible from regular settings.

These Samsung secret codes are especially useful when troubleshooting, authenticating a device, or simply discovering what your phone can do.

Now we can proceed to the Samsung codes list:

• Use with Caution: Certain codes can perform actions that are irreversible, such as factory resets. Always ensure you understand the function of a code before using it.
• Backup Data: Before using codes that can alter settings or erase data, back up important information to prevent loss.

Using these Samsung test codes, you can learn more about your device's operation and diagnose problems more easily.
