The Android developer options are hidden by default. It's not a consumer feature, so Google no doubt decided that it was better for people to not know that they're there, unless they need to use them.In this tutorial we'll show you how to enable the developer options in Android as well as how to disable them once again.
The developer options aren't just used by developers. USB Debugging is required by adb, which is used for rooting an Android device, backing it up, installing a custom ROM, taking screenshots from a computer, or doing many other things.So it is not recommended to open the "USB Debugging" Mode all the time,only when you need.
