There's little on the outside to suggest a massive upgrade over the Galaxy S III. On the other hand, the spec sheet implies a significant leap forward, improving on just about every aspect of the hardware and adding plenty of neew software features. As usual, the truth is somewhere in between and our job today is to put a finger on it

Design and handling

The Samsung Galaxy S4 design is the part that has changed the least compared to the Galaxy S III. The smartphone uses the same Hyperglazed finish, on account of which the predecessor was bashed for feeling like a plastic toy rather than a flagship proper. And the Galaxy S4 will most likely receive the same criticism. After all, it doesn't come anywhere near the premium feel of a Sony Xperia Z, let alone the HTC One.

This is not to say though, the Samsung Galaxy S4 looks worse than its predecessor. The new texture gives it a more serious and stylish look, while the improvements to the design also contribute to the overall appeal. The slimmer bezels leave more space for the brilliant screen (more on it later), while the slimmer body has a more high-end vibe. We are positive too that many will appreciate a black paintjob.

The size of the Galaxy S4 is a marvelous achievement, which should not be overlooked. The smartphone is the exact same height as its predecessor, but is 0.8mm narrower, 0.7mm slimmer and 3g lighter, while featuring a 0.2" larger screen, a higher-capacity battery that's still removable, and a host of new sensors and radios.

We guess Samsung has to share some of the credit with Corning and its new Gorilla Glass 3 that the Galaxy S4 employs. Based on a completely new glass composition, the third generation of the popular screen coating offers increased impact and scratch resistance, so Samsung could probably get away with using a slimmer shield, while maintaining the same level of protection. In fact the early tests are showing that the Galaxy S4 is actually harder to scratch than its predecessor.

At any rate, despite all the new features it introduces, the Samsung Galaxy S4 is easier to handle than the S III. It also feels more comfortable in the hand than the HTC One and that one only has a 4.7" display. Samsung has shown to competitors that a 5" screen doesn't necessarily make for an unwieldy handset.

1080p Super AMOLED display is what geeks' dreams are made of

One of the most important updates that the Samsung Galaxy S4 brings is the new 5" Super AMOLED screen of 1080p resolution. While it does have a PenTile matrix, the 441 ppi pixel density makes sure you won't be able to spot the hated cross-hatch pattern.

The defect wasn't easily spotted on the Galaxy S III either unless you looked from a closer-than-comfortable distance, which is to say it was as good as invisible to the naked eye. The design of the PenTile matrix has been changed too, so now green sub-pixels are twice as many as blue and red sub-pixels and the arrangement is changed. This however matters little to anyone not armed with a microscope.

What you should take away from all this is that the final weak point of the Super AMOLED screens has been taken care of and the Galaxy S4 offers image quality like no other smartphone on the market. Its impressive contrast and almost perfect viewing angles make everything on the screen pop-up regardless of your view point.

The color saturation is beyond the reach of any LCD out there, which make even the dullest image appear remarkably vibrant. Still, if you are not a fan of the oversaturated look of the AMOLEDs Samsung gives you the option to tune down the saturation to more natural levels and enjoy the best of both worlds.

The brightness levels of the Samsung Galaxy S4 is slightly higher than the rest of the company's AMOLED displays, which is to say not very high. However, due to the low reflectivity this doesn't affect outdoor performance.

Display test	50% brightness			100% brightness
	Black, cd/m2	White, cd/m2	Contrast ratio	Black, cd/m2	White, cd/m2	Contrast ratio
Samsung I9500 Galaxy S4	0	201	∞	0	404	∞

Sony Xperia Z	-	-	-	0.70	492	705

Apple iPhone 5	0.13	200	1490	0.48	640	1320

Of course, Nokia showed that a brighter AMOLED can do even better in direct sunlight, but the gain isn't dramatic. We'll make sure to do a sunlight legibility test for the review and find out all about that.

cheap Windows 8 upgrade

Cheap Windows 8 upgrade may require your Windows 7 key

Microsoft might ask you to enter your Windows 7 key during the process in order to qualify for the $14.99 upgrade.

People who bought a Windows 7 PC on or after June 2 can upgrade to Windows 8 Pro for just $14.99, but they may have to supply their Windows 7 product ID.

Microsoft kicked off registration for the $14.99 deal in August. Anyone who bought or will buy a new Windows 7 PC between June 2 of this year and January 31 of next year can upgrade to Windows 8 Pro for that special price. Shelling out the $14.99 lets you download a copy of the Windows 8 Upgrade Assistant, which helps you install the new operating system.

The deal cuts $25 off the standard Windows 8 Pro upgrade, which costs $39.99 to download for Windows XP and Vista users and Windows 7 users who purchased their PCs before June 2. People who want an actual installation disc have to cough up $69.99.

The $14.99 upgrade process typically asks you to enter the name and manufacturer of your Windows 7 PC, and the date you bought it. You'd then receive one of two notices, either a Success message telling you that you qualified, or a Sorry message breaking the news that you didn't qualify.

But in my experience, that process seemed a bit buggy.

I tried to register for the $14.99 upgrade last week with three different PCs, all from Lenovo and all purchased after June 2. One PC qualified for the upgrade, but two did not, with no explanation why. I tried the process a few times with the two failed PCs, but each time I came up empty.

I again tried the process on Tuesday and this time discovered that Microsoft now asked me for my Windows 7 product ID as additional proof. After entering the ID -- success. I now qualified for Based on various online comments, other recent Windows 7 PC buyers were bumping into the same initial problem of being rejected for the offer.

However, the requirement for the Windows 7 ID seems to be random.

Some people told me that they were asked for their Windows 7 key in the past and pointed out that this is not a recent change. But others have said they've never been asked for the key, not even in recent attempts. I contacted Microsoft to ask about this inconsistency, and a spokesperson e-mailed me the following statement:

The Windows Upgrade Offer process will dynamically adjust the registration process based on a variety of factors that take into account individual, local market, and global circumstances. Some users are required to provide additional purchase details online or offline in order to validate their registration. If eligibility cannot be determined using the online process, customers may need to contact customer support and provide proof of purchase to support.

So it seems to be a hit or miss process as to whether you'll have to supply your Windows 7 product key. But in my experience, providing the key was the only way I could qualify for the upgrade.

The offer limits you to five PCs, and you can install the Windows 8 upgrade on any PC, not necessarily the one with the product key that you use to qualify. The $14.99 and $39.99 deals both end January 31. So those of you want to upgrade to Windows 8 Pro should take advantage of those prices while they last.

In 3 days, Apple sells 3 million iPads

SAN FRANCISCO/NEW YORK: Apple sold 3 million of its new iPad minis in the first three days the tablet computers were available, driving optimism for a strong holiday quarter despite intensifying competition.

Sales of the 7.9-inch iPad mini and fourth-generation 9.7-inch version, both Wi-Fi only models, were double the first-weekend sales of the Wi-Fi iPad sold in March, Apple said on Monday.

Apple did not break out numbers for the crucial iPad mini, a smaller version of the original tablet designed to spearhead its foray into a segment now dominated by Amazon.com Inc's Kindle Fire and Google's Nexus 7.

Analysts estimate that about 2.3 million of the new iPads sold over the weekend were the mini-tablets, surpassing expectations of 1 million to 1.5 million.

Wall Street, which was disappointed with Apple's latest quarterly earnings, had been looking to the iPad mini to boost demand during the crucial year-end holiday shopping season as competition reaches a fever pitch. Microsoft became the latest major entrant to the market last month with the Windows-driven Surface.

While lines for the new iPads appeared lighter than usual for a new Apple product when they began selling at stores on Friday, the company said demand was so strong that it "practically sold out of iPad minis."

Apple had never before introduced two different iPad models in one quarter. Raymond James analyst Tavis McCourt said that while the sales numbers looked good, the company would need to sell another 20 million iPads this quarter to meet his estimate.

"There's still a lot of wood to chop in the quarter," McCourt said.

The company said it had already shipped many of the new iPads ordered before the release date, but some would not be sent out until later this month.

"We set a new launch weekend record and practically sold out of iPad minis," Apple Chief Executive Tim Cook said in a statement. "We're working hard to build more quickly to meet theincredible demand."

Holiday sales crucial
Apple shares closed up 1.35 per cent at $584.62 on Nasdaq on Monday, but that was still 17 per cent below the record high set in September.

The strong sales numbers for the iPads came despite both the iPad mini and fourth generation iPad being priced much above competing tablets. The iPad mini's $329 price had prompted some analysts to conclude that the higher price tag may hurt demand.

But Apple is still maintaining its industry leading margins with the smaller tablet, according to a teardown analysis of the tablet by research firm IHS iSuppli.

The Wi-Fi only iPad mini carries a bill of materials of $188.00, IHS iSuppli said, adding that the cost goes up to $198 when manufacturing expenses are added in.

"This differs markedly from Amazon's 7-inch Kindle Fire HD and Google's Nexus 7 tablets, both of which are essentially low-margin or no-margin giveaways at a $199.00 retail price," AndrewRassweiler, senior principal analyst, teardown services, for IHS, said.

But the California company's dominance of the tablet market eroded in the third quarter as both consumer and commercial shipments declined, partly as people waited for the new iPad mini, while rival Samsung Electronics more than doubled its share, according to tablet shipment numbers from research firm IDC.

Apple's share of the tablet market fell to 50.4 per cent from 59.7 per cent in the third quarter while Samsung was No.2 with 18.4 per cent followed by Amazon with 9 per cent. Samsung's market share a year ago was 6.5 per cent.

The 7.9-inch iPad mini marks Apple's first foray into the smaller-tablet segment and is the company's first major new device since the death of co-founder Steve Jobs last year.

Versions of iPads with both Wi-Fi and cellular connections will not ship in the United States for another few weeks. And both will be available in more countries later this year.

Apple heads into the current quarter after refreshing almost all of its product lines, from Macintosh computers to tablets.

"We believe the iPad mini has the opportunity to surpass the sales of the regular-sized iPads over the next several years," said Topeka Capital analyst Brian White.

Now, enjoy Android apps on Windows-poly tech mate

HOUSTON: Soon many of you will have a chance to add applications from the most popular mobile operating system, Android, to the most popular desktop system, Windows and enjoy technological marvel, thanks to the Chipmaker AMD and Bluestacks.

Advanced Micro Devices (AMD) and BlueStacks have teamed up to let consumers run Android apps on their AMD-powered PCs. BlueStacks, creator of a Windows app that enables you to run Android apps on Windows, has joined forces with AMD to bring their cross-platform application to AMD-powered tablets and PCs.

The two companies have teamed up to bring 500,000 mobile Android apps to Windows PCs through the AMD AppZone Player starting Thursday.

AMD is also working with its partners to pre-load the the BlueStacks Android App Player on AMD-powered Windows 7 and 8 laptops, desktops, and tablets.

If you don't want to wait for a new PC you can download the master Android on Windows app, AMD AppZone Player.

Or, you can simply download an Android app from the AMD AppZone and it will automatically install the player in addition to the app.

The partnership between BlueStacks and AMD, which has invested in the software company, focuses on optimising Android apps for AMD-powered Windows devices.

While Intel-powered PCs can access Android apps through BlueStacks' original Windows software, the AppZone Player is optimized for AMD's GPU and APU technology.

Manju Hegde, corporate VP of Heterogeneous Applications and Developer Solutions at AMD said, "BlueStacks' cross-platform innovation bridges the Android and x86 application ecosystems, providing new opportunities for developers and better experiences for users.

"By collaborating with BlueStacks we are enabling software developers to more easily tap into the full capabilities of AMD's products, and providing millions of consumers with great experiences as they can now run Android apps on AMD powered devices."

BlueStacks is an AMD Ventures-backed software company that enables Android apps to run on notebooks, desktops, all-in-one PCs, slates and tablets.

ANDROID OPERATING SYSTEM AT RISK-POLYTECHMATE

Android phones vulnerable to remote data wipes-polytechmate

WASHINGTON: Cellphones using Google's Android operating system are at risk of being disabled or wiped clean of their data, including contacts, music and photos, because of a security flaw that was discovered several months ago but went unnoticed until now.

Opening a link to a website or a mobile application embedded with malicious code can trigger an attack capable of destroying the memory card in Android-equipped handsets made by Samsung, HTC, Motorola and Sony Ericsson, rendering the devices useless, computer security researcher Ravi Borgaonkar wrote in a blog post Friday. Another code that can erase a user's data by performing a factory reset of the device appears to target only the newly released and top selling Galaxy S III and other Samsung phones, he wrote.

Borgaonkar informed Google of the vulnerability in June, he said. A fix was issued quickly, he said, but it wasn't publicized, leaving smartphone owners largely unaware that the problem existed and how they could fix it.

Google declined to comment. Android debuted in 2008 and now dominates the smartphone market. Nearly 198 million smartphones using Android were sold in the first six months of 2012, according to the research firm IDC. About 243 million Android-equipped phones were sold in 2011, IDC said.

Versions of Android that are vulnerable include Gingerbread, Ice Cream Sandwich and Jelly Bean, according to Borgaonkar. He said the Honeycomb version of Android, designed for tablets, needs to be tested to determine if it is at risk as well.

Samsung, which makes most of the Android phones, said only early production models of the Galaxy S III were affected and a software update has been issued for that model. The company said it is conducting an internal review to determine if other devices are affected and what, if any, action is needed. Samsung said it is advising customers to check for software updates through the "Settings: About device: Software update'' menu available on Samsung phones.

Borgaonkar, a researcher at Germany's Technical University Berlin, said the bug works by taking advantage of functions in phones that allow them to dial a telephone number directly from a web browser. That convenience comes with risk, however. A hacker, or anyone with ill intent, can create a website or an app with codes that instruct the phones linking to those numbers to execute commands automatically, such as a full factory reset.

The phone's memory card, known as a subscriber identity module, or SIM, can be destroyed remotely in the same way, Borgaonkar said. "Vulnerability in Android can be exploited to kill the SIM card permanently by clicking a single click,'' he wrote. "After the successful attack, the end user has to go to the mobile network operator and buy a new SIM card.''

While Borgaonkar has drawn attention to the problem, it's unclear how useful the vulnerability would be to cybercriminals who are primarily interested in profits or gaining a competitive advantage, said Jimmy Shah, a mobile security researcher at McAfee. "There's no benefit to the attacker if they can't make money off it or they can't steal your data,'' Shah said. "It's really not that useful.''

But the technique could cause huge headaches if it were harnessed to issue outbound phone calls, said Mikko Hypponen, chief research officer at F-Secure, a digital security company inHelsinki, Finland. "If that would be doable, we would quickly see real world attacks causing phones to automatically dial out to premium-rate numbers,'' he said.

Samsung Galaxy Tab 10.1: US court asked to reconsider ban

A US appeals court ruled on Friday that a lower court should reconsider a sales ban against Samsung’s Galaxy Tab 10.1 won by Apple in a patent dispute with the South Korean electronics maker.

The injunction was put in place ahead of a month-long trial that pitted iPhone maker Apple Inc against Samsung Electronics Co Ltd in a closely watched legal battle that ended with a resounding victory for Apple last month on many of its patent violation claims.

However, the jury found that Samsung had not violated the patent that was the basis for the tablet injunction and Samsung argued the sales ban should be lifted. US District Judge Lucy Koh said she could not act because Samsung had already appealed.

In its ruling on Friday, the Federal US Circuit Court of Appeals in Washington said Koh could now consider the issue.

The decision comes just a month before the South Korean corporation is expected to unveil the second generation of one of its most successful devices, the stylus-equipped Note.

The Galaxy 10.1 is an older model, but the ban still hurts Samsung in the run-up to the pivotal holiday shopping season.

The world’s top two smartphone makers are locked in patent disputes in 10 countries as they vie to dominate the lucrative market, which is growing rapidly.

A US jury found during the just-concluded trial that Samsung had copied critical features of the iPhone and iPad and awarded Apple $1.05 billion in damages.
