A:Answer Easiest way to do YouTube is to go in settings on the TV and get the passcode to link your phone's YouTube app. The built-in Wi-Fi receiver isn't the best on the TV, but it will work. I've managed to screen-share my laptop on several occasions to view pics, movies, Pandora, and other music. For a budget 4k, it's not gonna be the best, but it definitely does the job. I hope this helps!
