Don't Believe Customer Service Reps
Occasionally Samsung customer service representatives will "confirm" updates to customers either over the phone or in an online chat. These customer service reps are almost always wrong.
Over the years, customer service reps have repeatedly fed customers bad information. For instance, they "confirmed" the Galaxy S6 Android Oreo update multiple times (Reddit and XDA-Forums) only for the device to stick around on Android Nougat.
So if you see information about the Galaxy S7 Android Pie update from customer service reps making the rounds, don't get your hopes up.
You should only get excited if Samsung itself confirms plans (blog post, announcement on social media, Pie beta, something like that) to bring Android Pie and the One UI to the Galaxy S7, Galaxy S7 Edge, and Galaxy S7 Active.
