In previous versions of Android the option to enable Developer Options was really clear. However in Kitkat Google decided to switch things up and hide Developer Options from regular users.
In order to enable Developer options you need to open Settings, then scroll down to the bottom and tap on About Phone, and then scroll down to the bottom again to locate your Build Number. Tap on Build Number a few times and you’ll see a countdown until Developer Options are enabled.
That’s it! Go back to the main settings page and Developer Options can now be found right above About Phone.
