I purchased a ue49NU8000 a couple of weeks ago and have noticed the dark shadow at the bottom of the screen sometimes (and bottom corners). Originally when clicking the Home button I had actually thought it was a deliberate shadow at the bottom of the menu! I've also got a similar slim line up the far left side of the TV that I sometimes notice, however this line is fractionally lighter than it's meant to be. It's only there for certain images on the screen, so maybe about 30% of the time. It's frustrating as it's a brand new TV... My old LG LCD TV never had issues like this and it must be due to the bottom edge led lighting. But I can tolerate these issues so long as they don't ever get worse! My wife doesn't seem bothered by these issues.

I've just purchased a Samsung UE49NU8000 TV and found the same issue. I've found that if I have the movie file (and subtitle file with the same name in the same folder) on my android phone then I can use Bubbleupnp to play the file on the TV with subtitles. There is no way of toggling the subtitles on or off once the movie is playing. I have also found the app Server Cast which does allow toggling of the subtitles whilst playing (it takes a few seconds as on toggling them the file loads again and then restarts at the same point in the movie). Ignore that the app warns that the TV shows it won't accept subtitles. Both apps require me to browse for the movie using the apps own file browser, I can't just select the file in my usual file browser (ES) and play a movie with subtitles. I hope this helps someone!
