Apple no doubt profited from the comparatively new iPhone 5, as Samsung's Galaxy S3 has likely reached its peak in terms of mass adoption. Amazingly, though, the iPhone 4S also outpaced the Samsung in the same quarter, selling 17.4 million units to the Galaxy S3's 15.4 million. Apple's iPhone models accounted for 1 in 5 of all smartphones sold globally in Q4.
Samsung and Apple have repeatedly volleyed for the "best-selling" position, with the Galaxy S3 taking the honor last September. And as the story goes each time these sales figures arise, Samsung will likely fire back with the Galaxy S4, or whatever its next flagship smartphone is called. Last we heard, Samsung may debut a Galaxy S4 this spring.
