Shipments for the full year of 2014, however, rose 4.4 percent, totalling 229.6 million units.
Apple's fourth-quarter iPad shipments fell 17.8 percent year-on-year to 21.4 million, while Samsung saw an 18.4 percent decline to 11 million over the same period.
But the biggest loser was Amazon, which clocked a 69.9 percent decline in shipments of its Kindle Fire range, falling from 5.8 million in the fourth quarter of 2013 to just 1.7 million in the same period last year.
"Although Apple expanded its iPad lineup by keeping around older models and offering a lower entry price point of $249, it still wasn't enough to spur iPad sales given the excitement around the launch of the new iPhones," Jitesh Ubrani, senior research analyst, Worldwide Quarterly Tablet Tracker, said.
"Meanwhile, Samsung's struggles continued as low-cost vendors are quickly proving that mid- to high-priced Android tablets simply aren't cut out for today's tablet market."
