Does your screen have issues? Test...
I had bought a galaxy s4 about a week and a half ago and I loved it, but I recently noticed that when watching videos in the dark (I watch Netflix in bed while the girlfriend sleeps) the screen would look very pixilated and "dancing around" in the dark scenes like the blacks couldn't decide what they wanted to do. It was only noticeable if I was watching in a dark room though. If I viewed it in a well lit room I couldn't see it. I went back to best buy and tried a demo unit and it did it too, and decided to get an HTC one, but I don't really like this phone as much as the galaxy and am wanting to come back, that said the HTC does not have this issue at all and the screen is brilliant. I looked for similar issues on line but I haven't found my issue being discussed. I'm thinking that maybe it only effected some handsets. Could some of you guys watch a movie or some YouTube vids in the dark to see what you guys think? Hopefully my issue is isolated.
