Apple Smartphone Secret Codes
Apple smartphone is one of the most popular smartphones today. It was developed by Apple. The Developers create various kinds of backdoor access through what is referred to as secret codes. With these codes, one can get much deeper into the smartphone's system. These codes are not meant for malicious intent, but to familiarise users with the system.
However, note that, some of these codes are universal while some are not. This makes some of the codes useless for some Apple smartphones while some are exclusive to specific models.
Be cautious and read the functions of the codes before you use them, as some can cause irrevesible effects to your smartphone like wiping your entire data and factory reset the smartphone.
