Hi dears, this article will list out all the tested, untested and GSM secret codes and hidden menu codes for Samsung Galaxy A55 .
What Are Samsung Galaxy A55 Secret Codes?
Secret codes on your Galaxy A55 are special hidden codes that allow you to access various settings, retrieve information, or test hardware functionalities that are otherwise not accessible through the regular menu options. While these codes can be useful, they can also be risky if used without proper knowledge, so proceed with caution.
Keep in mind that these codes might not work on carrier-locked devices unless the bootloader is unlocked. Additionally, some codes may become inactive after software or security updates. If a code doesn’t work, there’s no need to worry—it could be due to these limitations.
How to Use Secret Codes on the Galaxy A55?
To use secret codes on your Galaxy A55, simply enter the code as displayed in the example below. The code will automatically execute if it is compatible with your phone. Be aware that some codes may not function even if they are intended for your specific model. This could be due to various reasons, such as a locked bootloader, carrier firmware restrictions, or the impact of recent firmware or security updates. If a code doesn’t work, it’s likely due to one of these factors, so there’s no need to panic.
As you can see in the above screenshot, just type the code to your normal dialing keypad, and the code will just execute.
