Hidden Secret Codes for Android Phone Users


Software developers are known to craft secret passageways or easter eggs in their software that can only be accessed by having the right key. Well, since our world is increasingly digitized, we get access to all kinds of information that would be impossible to find just years ago.

Android has its fair share of secret codes hidden within itself. These codes were originally developed by software engineers and developers who worked on this operating system as means to troubleshoot and perform various procedures that were inaccessible to the wide audience.

Lucky for us, they have now become fairly accessible to regular audiences, although not all of them work anymore. That’s why we took it upon ourselves to create a curated list of Android secret codes that are still working.

Note: All the codes below are to be inserted inside your phone dial box.
