Why Facebook is suddenly smitten with Groups

(Credit: James Martin/CNET)
With the private social network fad in the rearview mirror, Facebook appears motivated to remind us that not only did it think in smaller sizes long before it was cool, but it has quietly grown its private spaces audience to 500 million people over the years.
That Facebook has an astonishing number of people -- nearly 41 percent of the network's total audience -- cornering themselves off into nooks and crannies isn't surprising. Groups have long been a convenient way to converse in closed circles. Rather, the unexpected thing here is that Facebook is choosing to just now draw attention to Groups, a product that it rarely talks about publicly, and one that's not particularly representative of Facebook's new mantra of being a mobile-first company.
Speculation, kicked off by a Bloomberg profile of Facebook chief Mark Zuckerberg, would have it that the company is readying the release of some type of standalone mobile application forgroup communication. Indeed, plenty of clues point in that direction. But Facebook isn't ready to commit to that vision -- at least publicly.
"I don't think we've necessarily made any plans, one way or another, around breaking it off as its own individual experience," Facebook Groups product manager Jimmy Chen told CNET. "I think it's a core use case that Facebook, the company, should be really good at. The tactics for how we do that are still up in the air."
And, yet, Facebook is being oddly outspoken about Groups, the private social network that predates the once-trendy Path and other mobile apps like Everyme and Couple, which seem destined for future obscurity.
Not Groups. During Facebook's most recent earnings call, Zuckerberg boasted uncharacteristically about the success of Groups, even calling it a "core product."
The company never reveals anything it doesn't want you to know, nor does it offer up stats about its singular products, save for purchases like Instagram and WhatsApp. Facebook, for instance, still hasn't shared how many people use Messenger, a much more talked about product with its own standalone app.
The most probable answer is that Groups are good for advertisers, an audience that Facebook needs to keep happy should it wish to continue to make billions every quarter. Affiliating yourself with a pact of people, especially if related to a hobby, is a stronger signal of your tastes than a "like" or a follow. That Facebook is sitting on affinity data for 500 million people is a powerful message not lost on advertisers.Why, then, does Zuckerberg want to draw attention to Groups?
Company-watcher Brian Blau, Gartner's research director of consumer technology, suspects that Facebook's sudden revelation was meant to remind advertisers that they can target their ads against Groups, which are likely representative of members' true interests.
Currently, advertisers can only reach group members through right-hand column placements inside groups. Facebook does not target ads based on Group membership, a company spokesperson said. That's not to say Facebook won't go in that direction eventually. And Altimeter Industry analyst Rebecca Lieb concurs with Blau's view.
"Groups are self-identified target audiences," Lieb said. "[Facebook] has been looking at so much data -- big data, third-party data, ad-network data -- but other advertisers just want to reach specific people who like specific things. It's much simpler than the data, actually."
The groups-are-good-for-advertisers theory matches up against Facebook's recent statements on the product and its newly unveiled intention of pointing people toward even more groups they might like.
Chen said that Facebook believes that sharing in closed spaces should be a core principle of the network. "As a person in society, you're a member of all sorts of different types of social groups, be they clubs, or teams, or societies, or an alumni group, or a neighborhood, or a fan group. And we think that Facebook should be the place where you go to share with those types of people."

On Monday, the social network even made an update to a Groups discovery page to highlight groups that your friends belong to and groups that are relevant to where you live.
"The more groups that I belong to, the more I'm demonstrating my preferences and my affinities to Facebook, and the more data Facebook has about me," Lieb said.
An alternate theory is that Groups, like WhatsApp and Messenger, promote private communication, making it an essential tool in the social network's strategy to reach another billion people. It's yet another product that the company can pitch to people disinterested in the public realm of sharing. And maybe it's one of the applications that Facebook will eventually let people use anonymously.
"One theme that should be clear from our work on products like Messenger, Groups, and Instagram is that our vision for Facebook is to create a set of products that help you share any kind of content you want with any audience you want," Zuckerberg said during the fourth-quarter earnings call. "A lot of the new growth we see is coming from giving people the tools to share with different size groups of people."
Whatever the reason, though, one thing is clear: Facebook has a renewed interest in this oft-forgotten product, and we should expect to hear more on Groups in the months ahead. At the very least, Facebook will work fast and furious to make the Groups experience on smartphones, now obscured from view in the mobile app, more than the afterthought it is today. Facebook can't, after all, have what it calls a "core product" be sub par on mobile.
"We haven't invested as fully as we are now," Chen said, referencing the Groups team's attention to mobile. "We think, to take the next step, we can do a lot better to make this a ubiquitous tool for everyone."

BARCELONA, Spain--If there's one thing I learnt at this year's Mobile World Congress show, it's that sometimes you have to look to the Chinese vendors for surprises. Where Samsung failed to really surprise anyone with the design of its new flagship handset, I found a few gems from the various Chinese manufacturers such as this one from Gionee.
Encased in a 5.5-mm thin metal frame, the Elife S5.5 packs a MediaTek eight-core 1.7GHz processor, a 2,300mAh battery and a 5-inch full-HD (1,920x1,080-pixels) Super AMOLED display.
I don't really know how the company managed to squeeze so much into this thin chassis, but Gionee beats Huawei's Ascend P6 (6.14mm) in terms of slimness.
Check out just how thin the phone is.

When I held it in my hands, I was basically impressed with the build quality, but the phone's lightness makes it feel like a toy in my hands.

The handset is powered by Android 4.2 (Jelly Bean) but with Gionee's own skin and gives it a very Symbian/MeeGo like feel. The UI felt pretty smooth and responsive, though.
The Elife S5.5 will be available soon in Taiwan, Southeast Asia and India. There's no pricing yet but the phone retails for $375 in China, so expect it to retail for around the same price when it debuts in these countries.
The touch-sensitive menu buttons aren't really obvious, and give the impression of more screen space.

The chips of Samsung's Galaxy S5 -- Exynos and Snapdragon

BARCELONA, Spain--Qualcomm and Samsung are back in the newest Galaxy device, the Galaxy S5.
The Korean electronics giant on Monday unveiled its newest flagship phone with a slightly tweaked design and updated specs. The Galaxy S5 has a 5.1-inch display HD screen and a 16-megapixel rear-facing camera with a bunch of bells and whistles that are supposed to improve the experience of taking and viewing images. The device also contains a fingerprint sensor and heart-rate monitor, as well as updated components.
When the Galaxy S5 launches in April, it will hit the market with two different processors -- its own Exynos chip and Qualcomm's Snapdragon. Some regions will get the Qualcomm version while others will receive the Samsung chip model, though specifics aren't clear right now. Using the two different application processors follows the same strategy Samsung employed for theGalaxy S4Galaxy Note 3, and other devices.
Here's a deeper look at the two chips that will power Samsung's newest flagship phone.Both chips give a good boost in processing speed over their predecessors in the Galaxy S4. However, neither are 64 bit like the processor used in Apple's iPhone 5S. That technology enables faster apps that can juggle large amounts of data more efficiently than the 32-bit processors common in smartphones and tablets today. Even if they were 64 bit, however, Android doesn't yet support the technology. Qualcomm already has unveiled several 64-bit processors, and Samsung said it will have 64 bit ready later this year.
Qualcomm Snapdragon 801
Qualcomm is the undisputed king of mobile chips and for good reason. The San Diego company makes some of the most advanced application processors in the industry, and it's years ahead of rivals with its 4G LTE technology. It also invented 3G technologies that competitors have to license. All of that equates to some of the best smartphone chips around.
For the Galaxy S5, Samsung chose to go with Qualcomm's new Snapdragon 801 processor. If the company follows the same strategy as the GS4, that's the chip that will power the US model of the device.
The processor is a slight update from the Snapdragon 800 that Qualcomm unveiled at the Consumer Electronics Show in January of 2013. The Snapdragon 801, announced at Mobile World Congress, includes integrated 4G LTE and 802.11ac Wi-Fi for fast connectivity. The chip also has a quad-core Krait 400 CPU with speeds of up to 2.5 GHz per core. It also has an Adreno 330 GPU for premium graphics.
Overall, Qualcomm boosted the performance of the CPU, GPU, digital signal processor, camera sensor, and memory components of the chip while keeping the software and other features compatible with its other processors to speed development for handset vendors. The Snapdragon 801 enables higher quality imaging, as well as improved mobile graphics and gaming, higher speed SD card memory, and hardware for dual-SIM service in China.
Compared to the Snapdragon 800 -- which is used in the Galaxy Note 3 -- the Snapdragon 801 has a 45 percent faster camera sensor, 28 percent faster graphics, 14 percent faster CPU, 18 percent faster digital signal processor, and 17 percent faster memory.
While the Snapdragon 801 is only a slight step up from the 800, it's a pretty big boost from the processor used in the Galaxy S4 -- the Snapdragon 600. Qualcomm announced the Snapdragon 600 and 800 at the same time, but the 600 hit the market earlier. That's likely why Samsung used that chip in the Galaxy S4 instead of going with Qualcomm's more premium processor.
The Snapdragon 600 boasted a 1.9 GHz quad-core CPU and a Qualcomm Adreno 320 GPU.
Samsung Exynos 5422
Samsung not only builds mobile devices but also makes many of the chips that power those products. It's the largest memory chip maker in the world, and it's making a bigger push with its application processor line. Its Exynos chips show up in many Samsung devices, and they again will be used in the flagship Galaxy device in some regions.

However, Samsung lags some rivals in the market when it comes to the latest advancement in mobile chips -- 64-bit processing. It also doesn't have a product for high-end smartphones that integrates the application processor and modem on one chip. Samsung's chip business told CNET that it likely will make such a chip,but it's currently following the strategy of making a standalone application processor for high-end phones.
For some Galaxy S5 models, Samsung will use the Exynos 5422, which also was announced at Mobile World Congress. The processor boasts eight ARM cores versus the four in the Snapdragon 801. Samsung has employed ARM technology that allows for four big cores that run at speeds up to 2.1 GHz and four small cores for speeds up to 1.5 GHz. When the phone requires heavy computing, all eight cores can run at the same time. The phone can also employ just one of the small cores for minor activities.
By comparison, the Galaxy S4 used the Exynos 5410, another eight-core chip. In the case of that processor, the big cores had speeds of up to 1.6GHz, while the small cores were 1.2GHz. Overall, the performance of the Exynos 5422 is up to 34 percent higher than previous Exynos Octa models, the company said.
"Basically we enhanced the performance of the whole application processor," Kyushik Hong, vice president of marketing for Samsung's system LSI business, told CNET. "It is based on the same process technology (28 nanometers, or billionths of a meter), but we tried to maximize the user benefits by enhancing the CPU and GPU and multimedia features."
One big difference from the earlier chip is Samsung's use of "heterogeneous multi processing," which allows for any combination of the eight cores to determine the best settings possible for tasks. That also improves battery life by not using more cores than are needed.

Samsung also uses a new technique called "hibernation" that improves battery life during video playback. An algorithm detects what parts of the image aren't changing often -- such as set behind characters who are talking -- and freezes the data transfer. Instead of the video having to reactivate the pixels over and over, they won't change until that part of the image itself changes.
Samsung also uses mobile image compression to decrease the size of display data by half. That minimizes the amount of memory bandwidth required and also helps with battery life. The compression technology and hibernation save power consumption by up to 10 percent compared with conventional technology and go along with Samsung's new mobile display drivers.
The chip uses the same GPU hardware as its predecessor, Hong said, but the company used software to maximize the performance of the GPU cores.
Along with Exynos, the Galaxy S5 uses other Samsung chips, including the camera sensors. Samsung uses what it calls Isocell technology, which improves colors and image quality in less-than-ideal lighting situations. In the technology, each pixel is isolated. That improves the light sensitivity of the sensor.
Basically what all of this means for consumers is much faster, better smartphones. Stay tuned to find out which version you'll get in your region.

To avoid Android pitfalls, Mozilla shoulders Firefox OS update burden

Something like this Mozilla reference phone, built with a processor from Chinese chipmaker Spreadtrum, will hit the market as a $25 device for customers who don't have the funds for higher-end phones.

BARCELONA, Spain -- Mozilla will take over some responsibility for issuing Firefox OS updates that carriers today have, a move that could help users avoid the fate of Android phone owners saddled with older operating system versions.
"We are pushing that envelope," Chief Technology Officer Brendan Eich told CNET. "We think we can get people on Wi-Fi upgrading through Mozilla."
That would mean a person could step into an Internet cafe then update the software as soon as Mozilla releases a new version or security fix, rather than waiting for a handset maker to build, test, and release the update through a network operator partner.
But, Eich cautioned, "We are not there yet." OS updates are a risky proposition for carriers, which don't want to risk bricked phones and the attendant customer support difficulties.
Part of the change is driven by the fact that carriers aren't necessarily going to be in the loop with Mozilla's $25 Firefox OS smartphone, announced this week at Mobile World Congresshere. For that phone, people often will buy the phone from a bin at a retail store, Eich said, picking a carrier later.
Operating system updates can be a sore point for smartphones. Most Apple customers upgrade operating systems relatively swiftly, but even mid-range Android phones often don't see new versions of the operating system. That leaves customers without new features, makes lives difficult for app developers struggling to support older models, and exposes people to security risks.
Firefox OS is still a young challenger in the marketplace, with the first phones going on sale in July 2013 in Spain, but now it's available in 15 markets, chiefly Eastern Europe and Latin America.Firefox OS risks this problem, too. Although Mozilla issues Firefox OS updates at half the rate it does with Firefox -- every three months instead of every six weeks -- that's still too fast for some. Alcatel skipped the Firefox 1.2 update because of some problems with the 1.1 update.
"In the next several months, we'll add 12 new markets," said Jay Sullivan, Mozilla's acting chief executive officer, at a press conference at the show Sunday. "Later in the year, we'll have a large focus on Africa and Asia."
