Global smartphone sales were up 50.5 percent from last year, and the success of the Android platform helped push HTC into the list of top 10 device manufacturers for the first time, according to Thursday data from Gartner.

Overall, mobile device sales totaled 325.6 million units for the second quarter, a 13.8 percent increase. Smartphone sales ate up 19 percent of that market, a 50.5 percent increase from the same time period last year.

Despite the jump, intense competition among device manufacturers resulted in price drops – good for the consumer, but bad for margins, Gartner said. The average selling price for LG devices, for example, dropped 27.8 percent during the quarter.

There was no shortage of demand for the latest smartphones from companies like Apple, HTC, and Motorola, but there were shortages of supplies, particularly AMOLED displays.

In late July, HTC said it will switch out the AMOLED displays in its Desire and Nexus One smartphones for Sony's Super LCD display (SLCD) due to demand. That same week, LG Display said that it may not be able to meet demand for screens for the Apple iPad.

When it comes to the iPad, the release of the popular tablet did not make a significant dent in smartphone sales, Gartner said.

"Crucially, as we predicted, the sudden growth in media tablets, such as the Apple iPad, did not appear to hold back smartphone sales," Carolina Milanesi, research vice president at Gartner, said in a statement. "We believe that most tablet users still feel the need for a truly pocketable, yet highly capable, device for those situations when it's inconvenient to carry a device with a larger form factor."

Globally, Nokia led the pack with 34.2 percent of mobile device sales in the second quarter, though that was down from 36.8 percent last year. Samsung jumped slightly to come in at number two with 20.1 percent, followed by LG with 9 percent, and Research in Motion with 3.4 percent.

Apple came in at number seven with 2.7 percent, up from 1.7 percent last year. It was followed by HTC, which made its debut in the top 10 with 1.8 percent, a 139.1 percent growth year-on-year, Gartner said.

In terms of mobile OSes, Android jumped past Apple's iOS to land at number three behind Symbian and Research in Motion. Android had 17.2 percent of the market, up from 1.8 percent last year. Apple still made slight gains, up to 14.2 percent from 13 percent.

Gartner attributed Android's growth to "a non-exclusive strategy that produces products selling across many communication service providers (CSPs), and the backing of so many device manufacturers."
