LG bends the rules and says the LG Optimus Vu sold 1 million units in South Korea17
We should add that while both the Samsung GALAXY Note II and the LG Optimus Vu both sold 1 million units in South Korea, Samsung accomplished the feat in 90 days while it took LG three times as long. And it would seem that LG is combining sales of both its LG Optimus Vu and LG Optimus Vu II units to reach the 1 million mark. That would seem to muddy the comparison with Samsung's model.
