Last week I tried to turn off the data sharing permissions in my Samsung TV. There are hundreds of sites receiving information.. So many that they are grouped alphabetically A-G H-K etc.
And each one has to be turned off individually, sometimes with two or more permissions.There's no "stop all" button. But there is an "allow all" (why would you) option that would be easy to hit by accident, should you turn off the permissions.
I've complained to Samsung UK nd made it clear that I do not give my permission. They have a month, then I'll complain formally to the ICO (ICO's advice when I spoke to them).
I have no doubt it won't make the blindest bit of difference. Unless lots of people do the same, which won't happen because most viewers won't even know, let alone care.
I only found out when my TV guide started putting an advert across the page - and I went in search of a way to stop it.
NB. Will never buy another Samsung TV, or indeed anything else.
