All the Smart TV's appeared with sub standard browsers that you could beat with a netbook (which was pretty poor at the time.) Since these are devices without any open source or alternative OSes, once the sales are done, then with each passing year how would a maker pay their programmers to keep them current?
You are seeing the results. Samsung does not write the Netflix and such apps but did use a web kit that was not very good to start with. So as the web sites demand more of the browser these Smart TVs are left farther and farther behind.
My fix was simple. Since I could see this coming I opted for alternatives like Rokus and PC on a stick solutions.
As we use the SMART HUB (SH) to watch Netflix, Amazon and other internet based services, the performance degrades over time. Examples include no link to internet including Netflix & Amazon, video continually stopping to rebuffer, built in web browser not accessing internet,. This worsens over time until little to no videos with play. All other devices on our wireless network work fine. The only solution we have is to reset the SH and reenter all of the passwords to the various service providers (Netflix, Amazon, etc.) Once reset the SH works flawlessly for about a month or more before the performance degrades again and we have to reset the SH again.
We have determined this is a problem with the SH program and not our wireless network or internet which is 18mbs down (ATT Uverse). Again, to fix the problem, resetting SMART HUB solve the problem immediately for a short period and this is repeatable so in no way can the problem be attributed to any of our equipment or our internet connectivity/speed. All other devices work fine including wireless PCs and smart phones.
Is anyone else having this problem or discovered a better fix than resetting and reentering passwords over and over again? I sent the same request to Samsung Tech Support.
