Windows-powered tablets accounted for five percent of the market, with unit sales up some 28 percent at 2.7 million, the survey found.

"Android consolidation continued as it was the chosen OS (operating system) for seven out of 10 tablets shipped in the market," says Strategy Analytics researcher Peter King.

"Android is continuing to make steady progress due to the wide range of vendors and wide range of screen sizes and price-points."
