Everyone has their own secrets, so does our phones. It is a popular practice among software developers to leave backdoors within the code, which essentially allow anyone with knowledge to get into the system at a much deeper level imaginable for an end-user.
These backdoors does not come with an ill intent, as most of the time, they allow the OEM or programmer to get into the hidden menu for testing and troubleshooting.
Back in those days, even the old-school brick phones had these, allowing people who knew about them to access service options and software information.
Nowadays, a hidden menu exists on most if not all popular smartphones, and to access it, you just need to input the right code. We will be listing the secret codes for the all new HTC One M8.
Since most hidden menus are manufacturer specific, some of these codes might be able to work on other HTC smartphone models.
