Apple holds a sizable lead over rivals in the American smartphone market, reporting a 39% share in the industry.

According to U.S. research group comScore, Apple led the way as the leading smartphone manufacturer during the three month average period ending April this year.

Unsurprisingly Samsung followed next, posting a 22% market share, followed by HTC with 8.9%, Motorala with 8.3% and LG with 6.7%.

Google Android topped the smartphone operating systems list, holding over half (52%) of the platform market share.

Apple’s iOS share increased 1.4 percentage points to 39.2%, while BlackBerry ranked third with 5.1%, followed by Microsoft (3%) and Symbian (0.5%).

The news follows recent claims that smartphones are set for a "watershed" year during 2013, with device shipments expected to close in on one billion units.
