Samsung definitely knows. If they didn't, they wouldn't be in business.
Physical device, yes. But they certainly would have the ability to track inventory carefully. You'd be surprised at the amount of information shared between retailers and vendors.
Channel checks aren't a valid way of measuring sales, or stock, at least in the way these analysts do it. They would have to check a wide swath of stores across the US (we're talking hundreds, if not thousands of them) for the results to be statistically relevant.
Because there's definitely a large number of devices in warehouses right now, or sitting in stores. Only, the only people that know how many exactly, are Samsung and the retailers. Too many devices sitting in those places are not a good thing, which is why samsung will never say how many there are. (Just like apple or HTC won't either)
No, not at all. Nowhere did I say that, but nice try attempting to stir stuff up.
Look, the S4 is selling. We know its selling. A lot. But analysts rarely, if ever, peg sales correctly. All this 'analysis' was meant to do was drive the stock price up. Like everything of this sort, its a guess of what the S4 may sell. It ignores the effect of competitors like the iPhone in the fall, and unknowns like the next iOS. I would expect these projections to be altered down after WWDC and the new iOS is unveiled. It's what always happens when analysts guess using things not based in fact.
Factual needs to be in quotes, because even this is not factual. It's a guess.
Ah yes, there's the inevitable dig. At least this time you're not pretending like you're interested in an impartial conversation.
