Using smartphones or any hardware connected to the web is already invasive enough to personal data. Corporations have users on the hook for that even if they own the hardware, they cannot use the hardware without agreeing to what the manufacturer can do and collect.
In a nutshell, that service allows Samsung to collect every little detail of daily usage of the device from the user. And I mean down to what they view, buy, drink, go, etc and then gives Samsung explicit permission to target the user with ads etc. Of course the language does not say that in its brief explanation in a pop-up notice if one attempts to turn it on, but read privacy notice that pop-up provides.
