Summary: a lot of the apps seems to be unfinished. have not been able to use a keyboard on the internet function. some movie apps do not appear correctly. For me the plasma would be better if it was not a smart tv. None of my devices which are Samsung work well with the tv. my phone or tablet which are Samsung s4 and galaxie note tablet.
Summary: I am currently on my second set. The TV emits a buzzing sound from the front of the panel which can be heard at the back of my room. If you are watching the set and you are directly in front of the set, you will hear a distracting buzzing/clicking sound. This can only be heard directly in front of the screen up to 20' away. If you are to the side of below, you won't hear it- unfortunately the best place to watch TV is in front of it.
