Connect your Device to Your Smart TV

Make sure to connect the peripheral device (only on android or PC) to your Smart TV prior to browsing for content. Please note that LG Smart Share doesn’t work with iPhone or Ipad also known as Apple products. This is for the reason that iOS of Apple is not compatible with LG Smart TV.

We end this guide with the goal of clearing the confusion of what a 3rd party app actually means. In this manual, we simply refer to apps that are allowed by LG to be installed as the apps contained in the LG content store. Conversely, we refer to the apps that are not included in the LG store. as 3rd party apps. Most of the latter didn’t even need to have software installed. This is with the exception of the hardware that is plugged into the back of the TV, which is by the way, technically not installed.

It just acts like a bridge from one device to another. Enjoy your content!
