I bought an S8 from Boost back in May and when it was stolen late last month, I discovered it has Samsung's Find My Mobile and Remote control services. Unfortunately, I wasn't able to recover the phone but I know it's unusable to the thief.
So I bought another, also through Boost. Long story short, this model of Galaxy S8 does not have Samsung's Find My Mobile and Remote options.
Why not? I paid pretty good money for identical phones, there's no reason they're not identically capable. If thats the sort of thing to expect, I'll start buying direct from Samsung.
