Samsung makes it very hard to uninstall this 'feature' and even kills threads about it on its web site support forum.
I had to got back to the shop I bought it from and threaten to return the TV as defective unless they sent instructions for permanently removing it.
Samsung, you should be ashamed of yourself, taking such an obviously anti-customer stance. My next TV certainly won't be a Samsung.
And hopefully several other people reading this won't buy a Samsung either. Vote with your wallet, folks!
