T-Mobile myTouchAndroid smartphone manufacturers like HTC and Samsung account for most of the fastest growing companies in second quarter global marketshare, research firm iSuppli reports.

iSuppli’s data shows that HTC — one of the leading Android device manufacturers with phones like the Droid Incredible, Nexus One, and Evo 4G — has grown dramatically with 63.1-percent growth over the first quarter of the year. Samsung wasn’t far behind with a 55.6-percent sequential rise, thanks to the success of its Galaxy S line of phones. Sony Ericsson, which only recently started shipping Android phones, saw a 15.4-percent increase in shipments. Motorola only saw a 12.5-percent gain, perhaps because the success of its Droid line of phones is mainly restricted to the U.S.

After multiple reports that Android has become the leading mobile platform in sales, the fact that Android manufacturers are now seeing massive gains in marketshare was to be expected.

iSuppli credits HTC’s success to the Evo 4G, which is Sprint’s flagship 4G cellular network device. The company also has plans to release a phone that supports LTE, a competing 4G cellular network standard, to keep up its image as a manufacturer that’s on the cutting edge. The firm also points out that Motorola has seen five consecutive quarters of growth starting in the second quarter of 2009 — something that was certainly buoyed by the success of its Droid line of phones on Verizon.
