Most of the times, secret codes aren’t always meant to do malicious things. Indeed, programmers or OEM can use these Secret codes to terminate problems. We have a compilation of secret codes that can work on different smartphones.

One of the most important uses of these Secret codes are to troubleshoot common problems like No WiFi issues, Slow charging,  battery drain and Network  issues  and some other useful testing and debugging.
