Strategy Analytics Survey

U.S. smartphone shipments slid 5.4% during the second quarter of this year to 24 million units shipped, according to a fresh report released by Strategy Analytics on Monday, which also said it was one of the “slowest growth rates ever experienced” in the U.S. smartphone market.

The company’s “Wireless Smartphone Strategies” service suggested that Android’s market share slipped to a 56% share of the market, from 60.6% in Q2 2011, as iOS gained ground from a 23% share during the second quarter of last year to a 33% market share in Q2 2012. RIM’s BlackBerry OS also lost ground and fell from a 10.5% share in Q2 2011 to 6.5% share during the second quarter of this year.

“Apple is [rumored] to be launching a new iPhone in the coming weeks, and that event, if it takes place, is going to heap even more pressure on Android in its home market,” Strategy Analytics said. The latest rumors suggest Apple will reveal the iPhone 5 on September 12th and launch it on September 21st.

While the shrinking share is noteworthy, a separate report conducted by Reuters recently suggested that Samsung’s shipments are continuing to crush Apple’s shipments. That’s, again, likely due to consumers waiting for the next iPhone and the incredible success of Samsung’s brand new Galaxy S III smartphone.
