A:Answer This is from Tom's Hardware:
Hey all....
This is a fix for those of you with a Samsung Smart TV and facing Smart Hub Issues.
Your apps may not be working or not showing up even though your internet and network is fine.
Plus you get a "Function not available" message when trying to reset. (quick fix for this is to change the 'source' to tv and try again.
Anyway, after speaking to Samsung support, they gave me an awesome fix. Here it is...
Please follow the below steps:
1. Changing the country code other than US (ex. Zimbawe). (INSTRUCTIONS BELOW)
2. Updating the Smart Hub app as per the respective country. (Allow the new apps to populate the Smart menus: this can take a minute or so depending on your internet speed.)
3. Once the Smart Hub is updated, reverting the country code back to US.
4. Again the Smart Hub apps will update.
5. Launch apps and Enjoy!
I will provide you with the link which has steps on how to change the country code, please follow the link.
