If you've ever wanted to develop applications for Android and try them out on your own smartphone, you need to have access to certain menus that aren't usually available for all users, mainly because they're not too useful for ordinary users. And that's the reason why you should download the APK of USB Debug.
How to access your Android's developer options
You have to bear in mind that to be able to use this application you need to enable this functions on your operating system. The latter is hidden if you're running Android 4.2 or above, the reason for which you have to go to Settings > System > About phone and press the build number 7 times. Not very intuitive but that's the only way to access these options.
Once you've done so, from this app you can control the developer menu that comes along with all the following categories that include different functions:
- User information input.
- Hardware accelerated rendering.
- USB-connected media.
The options within each category can be used by application developers to test their developments but also allow us to nose around and satisfy our curiosity if we want to try to make the most of all our smartphone or tablet's possibilities.
