Google's Android operating system captured a record-high 87.5 percent of the global smartphone market in the third quarter, a research firm said.

The survey released Wednesday by Strategy Analytics found Android's share increase from 84.1 percent in the same period a year ago, while Apple's iOS saw its share slip to 12.1 percent from 13.6 percent.

"Android's leadership of the global smartphone market looks unassailable at the moment," said Strategy Analytics' Woody Oh.

"Its low-cost services and user-friendly software remain attractive to hardware makers, operators and consumers worldwide."

Oh added that the dominance of Android poses challenges for Google, which offers the system for free to manufacturers.

"The Android platform is getting overcrowded with hundreds of manufacturers, few Android device vendors make profits, and Google's new Pixel range is attacking its own hardware partners that made Android popular in the first place," he said.

The report said global smartphone shipments grew six percent from a year ago to 375.4 million in the quarter, the fastest growth rate for a year.

According to the survey, the market share for other operating systems including Windows and BlackBerry fell to a minuscule 0.3 percent from 2.3 percent last year.

"BlackBerry and Microsoft Windows Phone have all but disappeared due to strategic shifts, while (Samsung's) Tizen and other emerging platforms softened as a result of limited product portfolios and modest developer support," said Neil Mawston, executive director of the research firm.

Microsoft unveils Teams tool for work collaboration
San Francisco (AFP) Nov 2, 2016 –

Microsoft on Wednesday unveiled its "Teams" tool for workplace collaboration, taking on rising star Slack in a hot market.

"Microsoft Teams is an entirely new experience that brings together people, conversations and content — along with the tools that teams need — so they can easily collaborate to achieve more," Microsoft Office team corporate vice president Kirk Koenigsbauer said in a blog post announcing the new product.

Teams is built into Office 365, which includes popular applications such as Word and Excel as services hosted in the internet cloud. Skype internet voice and video calling service is also integrated into Teams.

A preview version of Teams is available to businesses in 181 countries, with general availability expected early next year.

"We aspire to create a more open, digital environment that makes work visible, integrated and accessible — across the team — so everyone can stay in the know," Koenigsbauer said.

Microsoft's offering is a direct challenge to Slack, a three-year-old company that has become a leader in a crowded field of new applications aimed at helping workplaces move away from email.

Facebook last month also jumped headlong into this segment with its Workplace application, aiming to leverage the popularity of the leading social network used by some 1.7 billion people.

With some three million active users, including nearly one million paying for "premium" service, Slack has become one of the fastest-growing business applications as it focuses on workplaces coping with email overload.

Slack, Hipchat and similar applications offer instant messages and social network-style interfaces that allow for collaboration while bypassing often-clogged email inboxes. Microsoft acquired one rival, enterprise collaboration group Yammer, in 2012.

Slack posted an online message welcoming Microsoft "to the revolution" and playfully advising the behemoth that getting the service right was tougher than it might appear.

"Wow. Big news! Congratulations on today's announcements," read a message from the Slack team.

"We're genuinely excited to have some competition."
