I have an LG Smart tv, however, after reading all the license agreements, I refused to agree to them. I never allow it to connect to any networks, in fact, I turned off everything to do with wifi or ethernet. I use a USB flash drive to update firmware but aside from that, I use an Android iptv box with an STB Pro Emulator app and connect it to my LG smart tv. There are several reasons I do this but the main reason is to break any and all remote management that the LG Smart tv has and all the agreements that allow all the software and hardware on the Smart tv to use, block or do whatever they want with whatever I use it for. This isn't something you should take lightly as most people don't read all of the agreements and they can literally do whatever they like even though you own the tv, they prescribe the rules for using the software and hardware within. Buy yourself an android box with 3gb ram and 32 gb of rom with HD 4K at 60 fps and you will be miles ahead and without the headaches that come with the apps and the agreements. You can reset your LG tv so all the agreements are wiped out and the tv is back to factory status. Do some research on which android box to buy but you won't go too far wrong if you follow my suggestions.
Do you really want VOICE and Camera turned on ? I would strongly recommend you turn both off and forego the voice command convenience as its not something designed for your convenience, its designed to listen and work with the camera. Be Smart, leave your LG tv with microphone, voice, camera, ethernet and wifi turned off.
