Samsung announced today that it sold a total of 5 million Galaxy Note II units worldwide, following its announcement earlier this month that 3 million were sold. That means the South Korean-manufacturer moved 2 million 5.5-inch phablets in just under a month —surely thanks to its availability in the United States on AT&T. Sales aren’t as high as the Samsung Galaxy S III that competes side-by-side with Apple’s iPhone 5; however, it is interesting that a large chunk of customers want a larger handheld experience. Being available in various parts of Asia, Europe, North America, Latin America, Middle East, and Africa, the 5.5-inch device will likely have a strong holiday quarter adding to this month’s strong sales.
