I have a Samsung Galaxy Note 3
I followed the directions exactly and the adapter is still not working. My phone is charging and the movie is playing on the phone but the television screen is black. Yes, it's set on the right hdmi input and I tried turning everything off and back on to reset. This is frustrating because when I bought this adapter at bestbuy, most of the packages were taped due to being returned. Not a good sign. Now, on this site for almost every reviewer that says it works there's two more that say it doesn't. Maybe it's my televisions, Vizios and Philips. I'll contact the companies about compatibility issues and if no solution then I guess there will be one more taped up box at bestbuy.
