Who's the leading phone maker in the US? Samsung. Samsung take 25.7-percent of the market, gaining 0.1-percent this quarter. LG slipped 0.3 points to 19.1-percent, while iPhone maker Apple takes just 15-percent. Motorola is down 0.8 points to 12-percent, in fifth place sits HTC with 6.1-percent of the market, up 0.2 points this quarter.
