Samsung appears to be widening its lead over Apple in the titanic battle over smartphone sales, according to a recent survey.

Analysts forecast that thanks to its flagship Galaxy S III, Samsung sold about 50 million smartphones in the second quarter, according to a survey by Reuters. Apple, meanwhile, is forecast to have sold 30.5 million iPhones in the same period, according to the same survey of more than three dozen analysts by Reuters.

Apple reports earnings July 24, and Samsung reports July 27.

The high-stakes smartphone rivalry between Samsung and Apple have spilled into courts over alleged patent violations. The two consumer electronics titans are suing each other in courts around the world, and all eyes are on the July 30 start of a trial in the U.S. District Court of the District of Northern California. District judge Lucy Koh last month sided with Apple and granted an injunction against Samsung’s sales of its Galaxy Tab.

Samsung’s sales are helping Google’s Android operating system push further ahead of Apple’s iOS operating system in overall smartphone sales.

Android phones make up 51.8 percent of all smartphones in the United States compared with Apple iOS phones’ 34.3 percent and BlackBerry’s 8.1 percent, according to Nielsen research.
