Samsung’s Galaxy S4 Expected to Have Sold 10 Million Units by Next Week

Samsung has been making waves this year with their new flagship phone, the Galaxy S4, and now they may see the fruits of their labor. At first many simply saw the device as a mere upgrade from its predecessor the Galaxy S3, but it now reaches nearly 10 million sold! This is not an unprecedented feat for Samsung; in fact the GS3 reached the 10 million mark in late July last year after releasing two months earlier on May 29th, 2012. That in and of itself is an impressive accomplishment, but now Samsung is one-upping themselves. The GS4 has only been out for 21 days ago, launching on April 26th, and has already reached over six million units sold! Samsung’s co-CEO JK Shin has told the Korea Press that he expects the devices sales to reach the desired projection by the end of next week.

If this were accomplished, Samsung would have literally cut their turn around for upgrading Galaxy phones in half. So what made it possible for Samsung to break their own impressive record and reach 10 million sold in only a month? Much of it comes down to some subtle (and some not so subtle) differences in their marketing strategy. On the subtle side, the GS4 was immediately available upon release in North America from three major U.S mobile carriers, as opposed to the GS3 debuting a month after its European release last year. Availability allows products to reach such immense sales, but it is pointless without a good marketing strategy as backup.

Apple’s iPhone 5 came out September 21st of last year, and that was right about the time they began airing TV ads portraying their already successful GS3 as the “iPhone killer”. Their ads showed the massive pre-release lines that stretched for blocks stemming from the Apple store while people waited for the iPhone 5 talking about it’s new features that users were skeptical about such as the inverted headphone jack and new charging port. Then, as if their ears were burning, GS3 users would pop up and give a free display of the Samsung phone’s capabilities. Now even though this was an ad for the predecessor, Samsung’s placement of these ads simply tenderized the consumer market for the GS4 and planted the idea in their minds that Samsung is the new kid on the block, here to knock the iPhone down a peg. And it seems that playing off Apple’s marketing and user community in hindsight has worked brilliantly considering Samsung’s Galaxy S4 should be in 10 million pockets by the end of next week and stands poised as the iPhone 5’s biggest competitor.

Rumor: Google set to unveil Google Edition Galaxy S4 at I/O

noreply@blogger.com (Benny Wong) — Wed, 15 May 2013 04:09:00 +0000

Article cited from http://androidandme.com by Smartphonebay.net

According to Russell Holly of Geek.com, Google is gearing up to make a huge announcement tomorrow at I/O, completely out of left field. While we won’t see a new Nexus phone unveiled just hours from now, Holly is citing sources already at the developer conference that say we will see a “Google Edition” of the Samsung Galaxy S4 running stock Android.

Hardware wise, the Galaxy S4 is an absolute beast of a phone. A high-end processor, 5-inch full HD display, and fantastic camera are just a few of the hardware elements that make the S4 one of the best Android powered smartphones money can buy. Unfortunately, Samsung’s custom version of Android isn’t for everyone. The Google Edition of the Galaxy S4 would remedy that, not only giving consumers a chance to buy a non-Nexus stock Android device, but one with a removable battery and expandable storage as well.

How the Google Edition of the S4 would be sold, whether through Google Play or Samsung directly, is still a mystery. But supposedly it will work on T-Mobile.

As far as rumors go, this one is pretty out there. It’s strange that we haven’t heard anything about the Google Edition Galaxy S4 before now, some 12 hours until it’s supposed to be unveiled, but Holly and Geek.com have been on-point with Google related rumors in the past. There may be good reason to get excited for this one. Not long now until we know for sure.

Comment from Smartphonebay.net Staff:

Recently, T-mobile always publish google edition of Galaxy S series. It is not surprised to have Galaxy S4 Google edition released and distributed once again by T-mobile. Only one thing to doubt is why Galaxy S4 google edition still have no information until now. Would the delayed release of the press information be related to the the patent war among Galaxy S series and iPhone???

Samsung ready for 5G rollout in 2020, has reportedly pulled down 1Gbps in tests

noreply@blogger.com (Benny Wong) — Mon, 13 May 2013 17:40:00 +0000

Article Cited from Engadgets.com by Smartphonebay.net

LTE might be all the rage right now, but next generation mobile technology is already in the works. According to Korea's Yonhap News Agency, Samsung has successfully tested its 5G platform, pulling down data at 1Gbps in recent tests. The company apparently needed 64 antenna elements to pull the trick off, but says the technology will be available to customers by 2020 -- matching the European Commission's goal quite nicely. It may not be the fastest 5G test we've seen inrecent months, but we're not going to scoff at progress.

Comment from Smartphonebay.net:

5G mobile data transfer in 2020??? We may expect 5G may come much earlier than the time expected by Samsung. Nowadays, the mobile data transfer technology growing very fast and attracting much more investment than ever before. It is clearly that Samsung only expect a linear growth of the technology level but indeed it is growing exponentially in the real world. We wish to see 5G before the date when Samsung expected. Wish best luck for those scientists working so hard on this subject!!

LG Working on the Next Nexus, is This a Good Thing?

noreply@blogger.com (Benny Wong) — Mon, 06 May 2013 08:16:00 +0000

Article cited from http://androidheadlines.com by Smartphonebay.net

So we know that Google, like always, will be releasing a new Nexus this year. So far we have seen very little information regarding this next generation. Well lets get those rumor mills turning because we now know that LG is working with Google to produce the next Nexus phone as reported by The Korea Times.

LG partnered with Google to create the most recent Nexus, the Nexus 4, last year and it appears that Google was so pleased with their work that they will be trusted with manufacture of the next one! The Nexus 4 is a fantastic device and is set to become even better with the apparent release of an LTE model at I/O. However, there a few issues nearly many had with the device that LG will hopefully correct with the next iteration.

First off, the exterior LG crafted is beautiful. I’m looking at the device right now and it just screams quality. That is, of course, till you flip it over and see the massive crack down the back. Please LG you know that fantastic Gorilla Glass stuff? Don’t pretend you don’t know what I’m talking about, it’s right there on the front of the phone. Put that on the back! If for some reason the manufacturing process doesn’t work correctly, then go with some nice, non-glossy, polycarbonate. I’m sure you will put in a 1080p display, although I’m in the minority, I would rather keep the 720p display and get a nice bump in the battery department.

As far as CPU specs go, you can probably stick with the 2gb of ram. More and more each day it looks like 4.3 will be the next edition of Android. As the hardware requirements don’t usually bump up too much outside of full number updates, the RAM is probably a decent area to save a little money. The CPU can always use a bump to deal with some of the more graphic intensive apps we’ll be seeing later this year, but again LG made an excellent selection of CPU.

As you have probably noticed I’m not asking LG to bring all that much new to the table. Why? Well its quite simple, the number one reason I am excited LG will be returning is their price point. I completely expect the nexus 5 (or whatever they call it) to be around $300 once again. LG realizes that we don’t need a full metal uni-body chasis or even an Octocore CPU. Just a good, solid device at a price that makes it easy to purchase unlocked.

Are you all excited for the Next Nexus now that you know LG will be producing it? Or are you more excited for the Motorola X phone, or X Fon, or whatever the heck they call it. Let us know in the comments below

Comment from Smartphonebay.net:

It is nice for us to know LG is ready to product next Nexus. LG always give a very good outlook of the smartphone including Nexus 4. We wish the new nexus still has a fine crafted appearance together with best fit spec for highly demanding users.

Google denies battery-draining location bug in Google Now for iOS

noreply@blogger.com (Benny Wong) — Fri, 03 May 2013 10:30:00 +0000

Article Cited from bgr.com by Batterybay.net

Google Now was probably the best thing to happen to mobile devices in 2012. Google’sbrilliant virtual assistant uses location, search history and other data to automatically present users with information like the weather, driving directions to meetings and travel times, sports scores and more without any interaction required on the user’s part. After a long wait, iOS device users finally gained access to Google Now earlier this week when Google updated its iOSsearch app with Google Now functionality, but its arrival was marred by two problems: first, platform limitations on iOS and Google’s decision to forego push notifications make Now far less useful on Apple devices than it is on Android. Beyond that, an apparent bug in Google’s app is seemingly causing location services to stay on and drain users’ batteries.

The first issue is insurmountable, to an extent. The whole point of Google Now is that it gives us all of this great information before we even know we need it. Since apps are very limited on iOS in terms of what they can do while minimized, Now will never be as useful on iOS as it is on Android. Push notifications would have helped matters to a degree — Google could have alerted users when important new “cards” become available — but the app’s functionality would still be limited compared to the Android version.

The second issue is something that a number of users began complaining about shortly after Google Now became available on iOS. Once Now is enabled in Google’s search app, it keeps locations services alive even while minimized. Many users complained that the batteries on their iPhones and iPads were draining faster as a result, but Google issued a statement toLifehacker on Thursday denying any problems with its new app.

Reports that Google Now drains battery life are incorrect. We understand people’s concern about seeing the Location Services icon stay on when they use Google Now. Many apps that keep the icon on actually do drain the phone’s battery because they require very accurate location. (For example a navigation app has to run your GPS all the time to keep you from missing your turn.) Google Now is built very differently: it uses cell towers and wifi hot spots for much lower battery impact.

We extensively tested Google Now on iOS for months and didn’t see reports of significant battery impact — we would encourage you to try it in the Google Search app for a few days and we don’t expect you to see significant impact on your battery. If you are seeing a problem, please do tell us (just tap feedback in the app settings). We take user feedback very seriously.

Early reviews laud BlackBerry Q10's QWERTY keyboard and battery life

noreply@blogger.com (Benny Wong) — Wed, 24 Apr 2013 07:30:00 +0000

The first reviews for BlackBerry's latest Q10 handset are in, and while there were a few hardware related issues, many said the company's much-awaited return to a physical keyboard form-factor was worth the wait.

The BlackBerry Q10's QWERTY keyboard. | Source: BlackBerry

Reviews from TechCrunch, AllThingsD and CNET all have positive things to say about the Q10's keyboard, which apparently works well with the new BlackBerry 10 operating system despite its optimization for full touchscreen handsets like the Z10.

"The QWERTY keyboard is everything you remember about BlackBerry keyboards – and much more," writes ABC News' Joanna Stern. "The keyboard is well-made and well-spaced thanks to the metal frets separating the rows of keys."

Stern's assessment is in line with other reviews, which make note of how spacious the keyboard feels due to wider spacing and key separation. CNET calls the keyboard "the star of [the] show," and praises the intuitive nature of the large, ridged keys.

Powering the device is a dual-core 1.5GHz processor with 2GB of RAM, while storage capacity comes in at 16GB with support for up to 32GB microSD cards.

An obvious concession for a handset featuring a physical keyboard is the decrease in screen real estate. The Q10 boasts a square, 3.1-inch OLED display with a 720-by-720 pixel resolution good for a pixel density of 330 pixels per inch. By comparison, the display on the iPhone 5 trails slightly with 326 pixels per inch, though the difference is negligible.

Reviews disagree on battery life, however, as TechCrunch, CNET and AllThingsD give high marks for the handset's ability to run up to about 8 hours of continuous use. ABC found longevity to be short of the manufacturer's claims.

As with the Z10, BlackBerry's latest touchscreen model, the Q10 runs on the smartphone maker's BlackBerry 10 operating system. Although it was designed with full multitouch displays in mind, the OS handles both keyboard- and touch-based operations with ease. As expected from a smartphone with built-in keyboard, the Q10 excels at messaging, and specialized software like Hub and Balance worked well with the form factor.

Build quality is a mixed bag, with some enjoying the feel of the soft-touch back plate, which is made from carbon fiber/glass composite, while others say the flexible design detracts from the otherwise sturdy feel of the chassis.

"The cover though doesn't fit quite flush against the chassis, especially near the USB port, which is disconcerting," said CNET's Brian Bennett.

Moving to the camera, the Q10 offers the same picture quality as the Z10 as both units share the same module, while the latest BlackBerry 10.1 update brings HDR imaging to the 8-megapixel shooter. Image quality is supposedly similar to competing handsets.

Overall, reviews were positive for the handset, especially for users looking to move back to QWERTY keyboards after Apple's iPhone shifted the market toward multitouch displays.

BlackBerry's Q10 is slated for a May release and is expected to cost $249 with a two-year contract.

Leak: Samsung Galaxy S4 will be available on 26 Apr

noreply@blogger.com (Benny Wong) — Mon, 15 Apr 2013 10:51:00 +0000

Article cited from Engadget.com by Smartphonebay.net

Scrambling to find a launch date for the Samsung Galaxy S 4? Staples may have just dropped a hint. According to a leaked store training sheet, AT&T will be offering the next Galaxy phone on April 26th, followed by T-Mobile on May 1st and Verizon on the 30th. Bold lettering warns these dates aretentative but they are familiar, matching both the UK launch date and T-Mobile's own declarations. Naturally, we try to take these things with a grain of salt, though it's worth noting that the document asks stores to prepare GS 4 reservation signage on 4/15, one day before official pre-orders begin. It isn't an iron-clad case for the phone's launch by any means, but for the eager Galaxy fan, tentative is better than nothing. Skip on past the break for a peek at the full page.

Tin nanocrystals for the battery of the future

Enlarge Monodisperse tin nanodroplets in an electron microsopic image. Credit: Maksym Kovalenko / ETH Zürich (Phys.org) —More powerful batteries could help electric cars achieve a considerably larger range and thus a breakthrough on the market. A new nanomaterial for lithium ion batteries developed in the labs of chemists at ETH Zurich and Empa could come into play here.

They provide power for electric cars, electric bicycles, Smartphones and laptops: nowadays, rechargeable lithium ion batteries are the storage media of choice when it comes to supplying a large amount of energy in a small space and lightweight. All over the world, scientists are currently researching a new generation of such batteries with an improved performance. Scientists headed by Maksym Kovalenko from the Laboratory of Inorganic Chemistry at ETH Zurich and Empa have now developed a nanomaterial which enables considerably more power to be stored in lithium ion batteries. The nanomaterial is composed of tiny tin crystals, which are to be deployed at the minus pole of the batteries (anode). When charging the batteries, lithium ions are absorbed at this electrode; while discharging, they are released again (see box). "The more lithium ions the electrodes can absorb and release – the better they can breathe, as it were – the more energy can be stored in a battery," explains Kovalenko

Uniform crystals

The element tin is ideal for this: every tin atom can absorb at least four lithium ions. However, the challenge is to deal with the volume change of tin electrodes: tin crystal becomes up to three times bigger if it absorbs a lot of lithium ions and shrinks again when it releases them back. The scientists thus resorted to nanotechnology: they produced the tiniest tin nanocrystals and embedded a large number of them in a porous, conductive permeable carbon matrix. Much like how a sponge can suck up water and release it again, an electrode constructed in this way can absorb lithium ions while charging and release them when discharging. If the electrode were made of a compact tin block, this would practically be impossible.

During the development of the nanomaterial, the issue of the ideal size for the nanocrystals arose, which also carries the challenge of producing uniform crystals. "The trick here was to separate the two basic steps in the formation of the crystals – the formation of as small as a crystal nucleus as possible on the one hand and its subsequent growth on the other," explains Kovalenko. By influencing the time and temperature of the growth phase, the scientists were able to control the size of the crystals. "We are the first to produce such small tin crystals with such precision," says the scientist.

Larger cycle stability

Using uniform tin nanocrystals, carbon and binding agents, the scientists produced different test electrodes for batteries. "This enables twice as much power to be stored compared to conventional electrodes," says Kovalenko. The size of the nanocrystals did not affect the storage capacity during the initial charging and discharging cycle. After a few charging and discharging cycles, however, differences caused by the crystal size became apparent: batteries with ten-nanometre crystals in the electrodes were able to store considerably more energy than ones with twice the diameter. The scientists assume that the smaller crystals perform better because they can absorb and release lithium ions more effectively. "Ten-nanometre tin crystals thus seem to be just the ticket for lithium ion batteries," says Kovalenko. As the scientists now know the ideal size for the tin nanocrystals, they would like to turn their attention to the remaining challenges of producing optimum tin electrodes in further research projects. These include the choice of the best possible carbon matrix and binding agent for the electrodes, and the electrodes' ideal microscopic structure. Moreover, an optimal and stable electrolyte liquid in which the lithium ions can travel back and forth between the two poles in the battery also needs to be selected. Ultimately, the production costs are also an issue, which the researchers are looking to reduce by testing which cost-effective base materials are suitable for electrode production. The aim is to prepare batteries with an increased energy storage capacity and lifespan for the market, including in collaboration with a Swiss industrial partner.

Comment from Batterybay.net:
As a battery producer, we are always looking at the new technology. Recently, we introduced a nano-technology modified pore structure to enhance the battery capacity by reducing the electron lost during the transition process. And today, we got this exciting news that we may able to use nano-technology edited Tin ionic crystal to act as the electron supply. It will be much better then the Li-ion cells using nowadays. Hopefully, the pricing problem for producing this crystal is to be solved shortly so that we can have it on our vehicle or mobile device in the coming future.
