(FROM THE WALL STREET JOURNAL 2/2/15)

Qualcomm Inc.'s flagship chip won't appear in a much-anticipated smartphone from Samsung Electronics Co. this year. But the reason may have more to do with competing technology from the South Korean company than with rumored problems with Qualcomm's chips.

San Diego-based Qualcomm on Wednesday cited its failure to win a spot for its Snapdragon 810 chip in one high-profile smartphone as among several factors leading to a reduced revenue forecast for 2015. Qualcomm's shares have fallen 12% since the forecast, cutting about $14 billion from its market value.

Qualcomm didn't identify the smartphone or its maker by name, but industry executives and analysts say they believe the company was Samsung. They expect the company to use a version of an internally developed chip called Exynos for a coming high-end smartphone called the Galaxy S6.

A recent Bloomberg report linked Samsung's decision against the Snapdragon 810 to overheating problems with the chip. Qualcomm executives declined to discuss the subject in detail, but the company plans to issue a news release Monday with quotes from mobile-phone makers to undercut the notion that there are technical problems with the chip.

"There is a lot of misinformation out there about what is really happening," Cristiano Amon, a Qualcomm executive president who serves as co-president of the company's chip business, said Friday. "We feel very confident about the 810's leadership."

The Snapdragon 810, which combines computing and communications functions -- capabilities that sometimes reside on separate chips -- has distinguishing features that include support for ultrahigh-resolution video and extremely fast wireless technology.

Analysts have rated Qualcomm's recent Snapdragons as faster than existing Exynos chips, which Samsung has used in some past phones. But the next Exynos model could have a key difference.

Samsung's production lines recently began churning out chips based on its latest big advance in manufacturing technology. New production processes, which shrink the size of transistors on chips, can improve their performance and power consumption while also reducing their size and production cost.

Samsung hasn't disclosed technical details of the next Exynos, and a company spokesman declined to comment on issues surrounding the Galaxy S6 smartphone. But Samsung is widely expected to build the chip with its new production recipe, which creates transistors measured at 14 nanometers, or billionths of a meter. Qualcomm's Snapdragon uses 20-nanometer circuitry.

Samsung smartphones could use some new selling points. The company on Thursday reported a 64% drop in quarterly operating profit from mobile phones, while Apple's iPhone unit sales in the same period surged 46%.

Samsung executives, during a conference call Thursday, spoke optimistically about prospects for 14-nanometer production for use by both internal and external customers. They also said the company is in talks with other companies about using its Exynos processor in their products.

It isn't clear whether Samsung might use Qualcomm wireless chips in the Galaxy S6 alongside the Exynos processor, or whether Samsung might pick the Snapdragon 810 for other handsets. "I'm not expecting Samsung to drop Qualcomm across the board," said Patrick Moorhead, an analyst with Moor Insights & Strategy.
