USB Debugging Mode is a mode that can be enabled in your LG G6/G5/G4 or any other Android smartphone. What USB Debugging mode does is to ease a connection between your LG G5 and a PC with Android SDK (software development kit.) The Android SDK is a suite that aids the development of Android apps. A programmer uses this suit to code apps on a PC, test’s the application on the device and this can only be possible when the device is enabled for USB Debugging which allows the apps to be transferred to the device. Outside this important system access level, USB Debugging can also be used for non-development-related issues. It gives you absolute control of your smartphone. You are able to use some third-party tools to better manage your LG phone (for example, Syncios LG Transfer).
