Purchased an LG 4k UHD Smart TV 2 years ago, it quickly developed a problem with the Bluetooth/Networking module which also includes the remote cursor. Every time I use it it fails within a short period of time. Additionally, the Lan Connected/Disconnected notification randomly flashes on the screen which is very annoying.
I notified LG of the issue and inquired with their Email support and phone support several times. They would respond with a canned response, ask for info and then disappear each time, ignoring and pushing off the problem until it got worse and the warranty expired. I filed BBB and AG complaints where they did the same. They send you copied and pasted FAQ's and then disappear hoping you'll go away until the warranty is up. Just a horrible company
