USB debugging gives developers/users advanced access to the LG smartphone. Once the device is connected to a PC via USB cable, it will be put into debugging mode. This is necessary, for example, if the device is to be routed. Also, the popular MyPhoneExplorer application requires advanced access to synchronize contacts.

For security reasons, USB debugging should only be enabled on the LG smartphone when it is needed.

Note: To enable or disable USB debugging on the LG device, the developer options must be enabled.
