Samsung's booming smartphone shipments were estimated to have surpassed those of industry pioneer Apple in the last quarter, making Samsung the world's biggest mobile phone maker by revenue.

Jae Lee, a Daiwa Securities technology analyst, estimated that Samsung Electronics had shipped about 28 million smartphones in the third quarter, up from about 20 million last quarter, and had surpassed Apple's iPhone shipments. Lee expects strong sales in the next three months as Samsung continues to focus on an array of smartphone products.

Samsung spokesman Nam Ki-yung wouldn't comment on whether Samsung had passed Apple Inc. in smartphone sales, saying the company no longer provides its sales figures for handsets. It did say, however,that handset shipments jumped more than 20 per cent from lastquarter, and global smartphones sales were up 300 per cent from last year.

The Suwon, South Korea-based company said its handset revenues were 14.42 trillion won ($13 billion) in the third quarter, a 39 per cent jump from last year, and it forecast strong sales.

"Looking ahead into the fourth quarter, when industry demand is traditionally at its peak, Samsung expects sales of mobile devices to remain strong and flat panel TV shipments to increase," the company said in a statement.

The company said its telecommunications business hit a record in quarterly sales of 14.9 trillion won ($13.4 billion) — a 37 per cent increase from last year — with growth mainly due to strong Galaxy smartphone sales.

Apple-Samsung patent battle

The gains in smartphones came despite the South Korean electronics giant being locked in a global patent battle with Apple, which began legal action in April against Samsung for what it says is uninhibited copying of its iPhone and iPad designs.

Apple says the product design, user interface and packaging of Samsung's Galaxy devices "slavishly copy" the iPhone and iPad.

Samsung fought back with lawsuits of its own, accusing Apple of patent infringement of its wireless telecommunications technology.

Earlier this month, Samsung asked Japanese and Australian courts to block sales of Apple's new iPhone 4S in those countries over alleged patent violations.

Samsung is also appealing an Australian court's decision to temporarily ban sales of Samsung's new Galaxy tablet computer.

Samsung also said the third quarter saw increased demand for flash chips used in mobile devices and enhanced revenue in the business that creates mobile application processors and image sensors.

Quarterly profit down 23 per cent

The rest of the company fared less well, however. Quarterly profit slid 23 per cent as weaker demand for flat panels and computer chips offset smartphone gains.

Samsung, the world's biggest manufacturer of memory chips and liquid crystal displays, said Friday it earned 3.44 trillion won ($3.1 billion) in the three months ended Sept. 30, down from 4.46 trillion won ($4 billion) a year earlier.

The company's display panel business suffered a quarterly loss of 90 billion won ($81.5 million) and its revenue of 7.08 trillion won ($6.4 billion) was down 13 per cent from a year earlier. Samsung's semiconductor businesses had sales of 9.48 trillion won ($8.6 billion), a drop from last quarter.

In an attempt to win sales in the market between smartphones and tablet PCs, Samsung on Friday unveiled a new Galaxy Note, Yonhap news agency reported.

The Galaxy Note is smaller than tablet computers but offers the same features as other wireless devices with applications. Its 5-inch screen is bigger than the Galaxy S2 smartphone, and a digital pen can be used to write on the screen, Samsung said.

Yonhap says the Note will debut in Europe next month and then later in China, South Korea and other Asian countries.
