On Android devices, there are some advanced hidden settings and options for Android developers called Developer Options. Since most average users don’t need them. They are disabled by default. Although called the developer option, many of these features are also useful for average user, notably the USB debugging. The main function of USB Debugging is to establish a direct connection between Android device and computer so developers can transfer their apps to Android device for testing. It is also a key step for non-developmental activities. For example we need to turn on USB debugging, so we can root our Android Device, install custom ROM, install third-party apps, restore bricked Android device from computer. In this article, we will discuss how to enable Developer Options and USB debugging on Android phone. We will use an Android powered LG smartphone as the example. The same procedure should apply to many other Android devices as well, like Samsung, HTC, Motorola, Huawei, Xiaomi, ZTE, Lenovo, etc.
Open the Settings app on LG mobile, scroll down to the bottom, and tap About phone. If you see different tabs on the About phone screen, switch to the Common tab, then tap on Software info. Here you can find the Build number. Tap on “Build number” for 7 times in a roll, and then you will see the prompt message saying ‘You are now a developer’.
Go back to the Settings main screen, you should find the “Developer options” right above About phone. Tap on Developer options, touch the ON/OFF toggle to turn on Developer options on LG mobile phone. Once activated, you can then find and activate various advanced options beneath it, like USB debugging, show touches, background process limit, view and control running services, etc.
