Android is the most popular Operating System (OS) in the world today.  It powers millions of mobile devices in more than 190 countries around the world. The OS is developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices.

However, the developers created many backdoors through which you can enter into the system and you can change settings. The backdoors called “Secret Codes” are not meant for malicious purposes, because developers block some modes, they allow the users to enter into the system and familiarize themselves with the system.

These codes are the numeric/symbolic sequences which allow you to access system settings for several uses. Here are some hidden android secret codes that will enable factory-reset your device, find out its hidden camera information, instantly back up your precious data,  check baterry sattus  and lots more.
