When purchased from me 32 inch version, Amazon Instant Video and YouTube were not working app: impossible play crashes of Apps and all TVs, extreme load times Videos. The customer service from Samsung has played a cat-and-mouse game with ever new firmware versions to me about 6 weeks. This could be times not extract, sometimes not install it on the TV, or were older than those on the TV existing version, have not solved the problem in the end. In the meantime I bought the same unit again, because I was hoping that the wireless card of the TVs was simply broken. The new device has had the exact same error. On top of the poor customer service I was offered ultimately, to call with an employee of the multimedia department, which would also perform remote diagnostics. To this end it was agreed to forward a date. The employees do not bother another failure diagnosis or remote diagnostics, but represented from the start vehemently believe that the TV perfectly fine since (to my question how he knew that because "I know but our equipment") and the Error on the router that I use, the third-party apps, their servers or the Internet service provider are. Only of course, not on TV, because "the TV is just a TV, is not a tablet or smartphone and displays the video only." (How stupid that is, probably does not need to be explained.) It should be mentioned here that the router with a 100 Mbit / s Internet connection is running and other devices (including a very similar Smart TVs from Samsung) it work perfectly. But that was the staff continue to impress not, he advised me then to connect the TV via a LAN cable to the router. I returned the TV and then a LG 32LB580V ordered me running quite perfectly and smoothly on the same router. Amazon Instant Video and YouTube function properly. That was so my last Samsung TV: Life is good.
