Samsung has already announced the new Gear S2 smartwatch but on Thursday said during IFA that it would would make its next smartwatch technology available to its competitors who also use Google's mobile platform Android. Samsung did not give a price tag for the watch., which will be available as of October.

"We are leading the way in this segment," said Younghee Lee, Samsung's global marketing head for mobile. "But we realise we can't do it alone."

Apple Watch was the leading smartwatch in the second quarter, with an estimated 4 million shipped worldwide, for a market share of more than 75 percent, according to Strategy Analytics. Samsung followed with an 8 percent share.

Samsung launched its new watch on Monday. The Gear S2 comes with mobile payment technology just like Apple's Watch. It will work on Android - and for the first time, not just Samsung's Android phones. Meanwhile, watches running Google's Android Wear software will now work with Apple's iPhones.

The Gear S2 has a circular frame that can be rotated to scroll through notifications and apps. The watch itself is also smaller - roughly the size of the larger version of Apple Watch.

Its always-on communication features let users stay connected via notifications that allow them to check email and review their calendar, along with functions to send texts via pre-set messages, voice input, emoticons and a keypad. Along with 3G connectivity and an e-SIM card—a first for a wearable device-all of this is possible straight from the user’s wrist.

The Gear S2 also includes a number of sensors and improved tracking functions to monitor activity progress throughout the day, which is illustrated on a circular timeline. And, in a time when it’s more difficult than ever to stick to a fitness plan, the Gear S2 acts as a personal trainer (minus the hefty monthly fees) by sending messages of motivation when users have been inactive for a period of time, and praise when it recognizes that users have been exercising.

With the Gear S2’s embedded NFC technology, wallets can be left at home, as users can process payments with a tap on an NFC reader. Furthermore, Samsung is working with a number of partners across a variety of industries to expand the usability of wearables, from smart car keys to hotel room keys and remote controls.

These connected features are powered by a battery that can last two to three days.

Samsung says about 1,000 apps should be available when the S2 launches. That's promising, though less than Apple Watch's 8,500 and Android Wear's 4,000. So far, many leading app developers have focused on Apple Watch and Android Wear instead, as Samsung watches use the Tizen operating system. Samsung is letting app developers customize watch faces, so you can see baseball scores from ESPN or the latest posts from Twitter.

In a surprise move, Samsung is making the S2 work with a range of Android smartphones, though some features might not work with all phones.

Samsung's latest smartwatch will also face the competition from the new Moto 360 watches, which will come in three lines - men's, women's and a premium "Sport" version for fitness enthusiasts. Sport will have GPS built-in, along with a screen that can adapt to bright sunlight, with high-contrast text and graphics for better visibility in glare. Mix and match sizes, bands and bodies for $300 to $430. The men's and women's watches will come out in late September.

Huawei has also announced the Huawei Watch, which will have luxury versions, with bodies plated with rose gold, for $699 or $799. The Huawei Watch and the Apple Watch both start at $349.

On the flip side, Asus's new ZenWatch 2 will be notable for its price - starting at 149 euros ($167) when it comes out in October.

Huge tablet in sight

The South Korean company on Thursday teased what appeared to be a big-screen tablet or a 2-in-1 device, called the Galaxy View. The brief video -- which came at the end of a press conference detailing Samsung's Gear S2 smartwatch -- said, "Start with the limits. Then push them."

Samsung said it will "give you a closer look in October."

Apple reportedly plans to show off a large-screen tablet of its own, dubbed the iPad Pro, during an event next week. The device is expected to have a 12.9-inch screen.

Apple could show off the iPad Pro during its product launch September 9 in San Francisco.
