You can control your LG Sound Bar with this app from your smartphone.
Please note that this is not the official LG Sound Bar app, but you are enabled to work with it with this app.

Our app lets you choose the remote that best matches your device from a variety of remote models.

The app was developed to help you use your LG Sound Bar even if you cannot find your remote control. However, please be aware that the app requires your phone to have an IR sensor.
