The Galaxy S III continues to be the most popular Samsung smartphone in the US, but sales of newer devices like the Galaxy Note II and Galaxy S4 have helped the Korean manufacturer further widen its lead over the competition in the country, achieving a growth from 22 percent to 26 percent of market share. The figures were published in a study by the NPD Group – Apple saw its share get a much larger boost than Samsung’s, but it is still an indication that Samsung’s dominance among other smartphone players isn’t coming to a stall just yet, and the arrival of the company’s next flagship might just help its further strengthen its hold in the US smartphone market.
