Haven't we gone over this ? Apple reports the same thing, Shipped units, not end-user sold units, as it doesn't have the information for end-users sale outside its own retail channels.
Samsung reports shipped units, but guess what, if there was "channel stuffing" as people on here desperately want, then Samsung wouldn't be shipping more and more units quarter after quarter.
Just look at what happened to Apple from Q2 to Q3 this year if you don't believe me. Part of their sharp drop from 35M units to 26M units was that the channels had extra dormant inventory from Q2! So in essence, Q2's 35M units was SHIPPED units, not sold. And it resulted in a drop in unit shipments for Q3.
So again, logic is your friend. Retailers wouldn't keep buying more and more handsets from Samsung if they couldn't move those handsets. Samsung would have 1 record channel stuffing quarter and then zilch. Nothing, nada. As it stands, Samsung has been posting bigger and bigger quarters for quite some time.
So can we stop this "shipped vs sold!" nonsense.
