I've been to seminars where Samsung employees present and they definitely program "to specification." Other companies may "go with what works."
For example, over and over you find changing the DNS to 188.8.131.52 or other helps. I've asked for years why doesn't Samsung code that in?
I have noticed many posts about network interference and other issues with Samsung Smart TVs and other video products. I paid a premium for a Samsung Smart TV and have consistently battled issues with connecting it to the Internet both wirelessly and wired. It might connect for a while or not. I have spent many hours troubleshooting this issue and have finally given up. I connected a Roku device and have no issues streaming with it. This has definitely dampened my enthusiasm for all Samsung devices. Apparently there are many others who have experienced these same issues and I hope Samsung will hear these complaints and fix the problems.
