The sum of its selling points: hands on with Samsung Galaxy Nexus

The sum of its selling points: hands on with Samsung Galaxy Nexus
The Samsung Galaxy Nexus will be the first phone to market with the Android 4 operating system. It will be the first powerhouse to land on Verizon's network in a while, and one of very few 4G LTE phones on the network. There's a pile of reasons to lust after it, but there are a couple of aspects to the phone that make us apprehensive.We're only discussing the hardware here; a more in-depth look at the Android 4 OS will come in a follow-up piece.

In the hand, the Galaxy Nexus feels so huge, it's borderline silly. The screen measures 4.65 inches and there is about half an inch of bezel on either end, and feels like it's giving 7-inch tablets a run for their money.The body and front glass on the Galaxy Nexus are curved slightly, with the bottom much thicker and heavier than the top. The back is a crosshatched plastic panel that can be pried off easily for access to the SIM card slot and battery. The phone feels thin, though not quite as small as the Galaxy S II or Motorola Droid Razr.
The sleep button is on the right side towards the top with volume rocker is on the opposite side. The headphone jack and microUSB port are located on the thick bottom edge of the phone, and the only speaker is on the back of the phone, centered at the bottom. A small, pastel rainbow indicator light pulses in the bezel below the screen, though we can't even make out of the indentation where the light sits when it's off.

The Galaxy Nexus has two cameras: a front facing 1.3-megapixel one, and a rear 5-megapixel one. Google boasts that the smartphone's rear camera is "low-light optimized", but in our experience that only meant that the flash triggers very easily in low light situations. Even in a moderately well-lit indoor setting like in the photo featuring a cat, the flash popped. Without the flash, the same photo was pretty grainy. In less ambiguous light settings, the camera has a good level of detail but the color is a bit washed out. On the plus side, there is essentially no shutter lag and we can take a burst of pictures with a series of taps, though the camera will have a hard time maintaining focus from shot to shot.

The aforementioned giant Super AMOLED screen on the Galaxy Nexus is one of the first 720p displays we've dealt with on a smartphone. Its 720x1280 resolution means it can display a high level of detail and render text well, despite the fact that it's a PenTile screen. At the very least, the Galaxy Nexus leaves behind the obvious-pixel problems of 800x480 resolution displays that are stretched so thin on 4-inch-plus phones.

Even with the brightness all the way up, the screen has a yellowish cast similar to the Galaxy S II, though it's not quite as jarring. Some people prefer yellowish screens over bluish ones, so this may not bother many people at all. The screen is fairly readable in sunlight, though it definitely packs less maximum brightness than other phones.

We tried playing some videos on the Galaxy Nexus, and found that while the picture quality was fine, the phone's speaker is not very loud at the highest volumes—an average conversation could entirely drown the phone out. The speaker lacks depth, which is normal for a smartphone, but has less distortion than usual at the highest volumes, probably because it can't get as loud as most phones we've encountered.

Call quality on the phone was as good as we've heard on recent phones. We didn't hear any background noise or feedback, though the voices of our conversation partners were a little fuzzy.
We're not going to discuss the Android 4 operating system just yet—the OS is saving itself for Ryan Paul. But as far as performance, we get the sense that the OS is married much more closely to the hardware than older versions of Android were to their respective phones. We say this partly because interactions with the OS are very fluid in our use. Also, like on the Galaxy S II, the keyboard lets us type like the wind with accuracy, and it is sublime. But we say it too because even with its 1.2GHz processor and 1GB of RAM, the few benchmarks we ran do not hold the phone up as a contemporary of the iPhone 4S or Galaxy S II.
The Galaxy Nexus performs very well at the browser benchmark Sunspider 0.9.1, scoring 1990-2010 milliseconds on the test (the iPhone 4S hovers around 2200 milliseconds). But in Linpack, the Galaxy Nexus scores a modest 43-45 MFLOPS in single-threaded processes and 35-38 MFLOPS multi-threaded. For comparison, the Galaxy S II that launched in the US a couple of months ago scores about 93 and 53 MFLOPS, respectively.

The smartphone's performance in graphics rendering is likewise unimpressive. The Galaxy Nexus scores around 24 frames per second in the GL Benchmark 2.1 Egypt Standard test, and 40-42 frames per second in the PRO Standard test. For comparison, the iPhone 4S scores 58-60 fps on both of those tests. The Samsung Stratosphere, with its year-old hardware, scores 25 and 42 fps, respectively.

The Galaxy Nexus's battery is rated at 1750mAh, which is middling-to-high for the most recent batch of cell phones. The phone's Super AMOLED screen will help it to not lose catastrophic amounts of battery life, but it is running a new operating system on a dual-core processor, and the flagship version is on Verizon's LTE network. Our version of the phone was working off a T-Mobile SIM on the carrier's HSPA+ network, so we didn't get the full measure of intensive power consumption. Still, the battery indicator seems to empty out fairly fast, even when the phone is inactive.
Google and Samsung haven't released official battery estimates, but we found that the battery had some trouble lasting a full day of use. With WiFi on, full volume, and the screen at half brightness, we found the phone could play back video for 5.5 to 6 hours. Not terrible, but not great. This phone is likely shaking in its boots over the shadow 4G LTE access is casting (though the LTE version will have a slightly larger 1850mAh battery, according to Google's docmentation).
Overall, the Galaxy Nexus is a bit of a mixed bag. Performance is good as far as the operating system goes, but the benchmarks suggest apps could be harder for the phone to deal with than its competitors (to date, we haven't had any difficulty with any apps we've tried to run). The camera is good in most respects and the screen is pretty, but the battery life gives us concern, though we'd wait to see how it goes over on LTE in real time. We're also not sure what the advantage of curving the phone's body is, be we suspect only Raffi (NSFW) knows the answer.

This phone is exciting because it's the first with Android 4 and is on the best-reviewed network, but it's not quite a dream come true. Just out of interest, I went to Wikipedia to look up the exact original meaning of the word "flagship". The entry reads, "Because its primary function is to coordinate a fleet, flagships are not necessarily more heavily armed or fortified than other ships." Sounds about right.
And remember, in the next part of this review, Ryan Paul will discuss the real-world execution of the Android 4 operating system.
Good
  • Screen is highly detailed, can play 720p video
  • Camera's pictures are nice with decent lighting
  • Phone feels decent in hand, and people with bigger hands may find it more comfortable to use than sub-4-inch phones
  • Performance is smooth, in spite of lackluster benchmarks
  • Ice Cream Sandwich OS is delicious in ways that you will find out
Bad
  • Curved design is a little weird
  • Speaker can't get very loud
Ugly
  • Battery has potential to flounder on 4G LTE

Apple Suppliers Already Shipping iPad 3 Displays

The latest report comes from Digitimes, which has claimed makers of iPad displays including Samsung, LG, and Sharp shipped one million high-res panels for the iPad 3 in October. It also said these suppliers will increase shipments to two million units in November. We're entering that special time of year. No, not the season when people begin to wrap presents and trim their trees, but those months leading up to the period when it's assumed that Apple will launch its next-gen tablet that iPad rumors abound. 

It alleged that Apple is developing a new 7.85-inch panel, and suppliers AU Optronics (AUO) and LG have already sent samples to Apple. However, Digitimes said it couldn't determine whether or not Apple would add an iPad of this size to its line next year.Apple will begin assembling the third iPad in January of 2012, Digitimes also said.Meanwhile, All Things D reported last month that evidence in supply chains (such as increased iPad orders) suggests the rumored iPad 3 is headed into production. It also predicted that the device will appear sometime in March. That's a logical assumption since the iPad 2 was released on March 11 of this year. 

Digitimes' latest report didn't mention any specifics about the resolution, which has been a heavily discussed aspect of the next iPad, especially considering Apple didn't upgrade the iPad 2's display. There has been chatter that the iPad 3 would feature a retina display, but CNet claimed recently that the company has struggled to reach the level of pixel density necessary, and it said Apple might instead go with the intermediate option of 1,600x1,200 resolution.As far as specs go, Digitimes said they'll be similar to the iPad 2. There have also been rumors that the iPad 3 will be iPad 3 will be lighter and thinner.

Apple Originally Planned AMD Chip for MacBook Air

Apple logo
Taking into account the surge in popularity, the rumors that Apple will either add a 15-inch MacBook Air or slim down its MacBook Pro line don't come as much of a surprise. What about Apple's plans for future MacBook Airs? They could include ARM chips, SemiAccurate also claimed. Instead, the MacBook Air, which Apple debuted back in July, is supported by Intel's Sandy Bridge i5 and i7 processors with integrated graphics. "Sources indicate that ARM CPUs are still on tap as soon as the 64-bit chips show up," SemiAccurate also said. One thing is certain: the MacBook Air isn't going anywhere.
 
According to a Morgan Stanley report that surfaced last week, these ultra-thin laptops now comprise 28 percent of Apple's notebook shipments, up from just 8 percent in the first six months of 2011.The uptick was most likely prompted by Apple's summer update to the Air line.
Apple's current MacBook Air isn't the original notebook the company had planned. SemiAccurate has claimed Apple had a MacBook Air based on Advanced Micro Devices' (AMD) Llano chip very close to production last spring, but it cancelled it last minute. 

"If you are wondering why the Air wasn't really revamped much this last time, it is because you are looking at plan b," SemiAccurate wrote. "Plan A was basically a low power Llano in an Air shell, and that would have been a really tasty machine."

So just why didn't Apple go the AMD route? SemiAccurate said that "AMD dropped the ball." On top of that, Apple allegedly had concerns with supply, and it ultimately chose Intel over AMD. 
Apple did not respond to questions about its chip choices.

Why Apple rejected AMD's Llano in the MacBook Air

Why Apple rejected AMD's Llano in the MacBook Air
Apple's MacBook Air may have come close to shipping with AMD's "Llano" integrated CPU and GPU processors this past summer. According to unnamed sources speaking to SemiAccurate, Apple had Llano-based MacBook Air prototypes "on the verge of production" but ultimately decided on Intel's ultra-low voltage Sandy Bridge processors instead. Assuming it's true that Apple was tinkering with Llano processors in its popular ultraportables—and we think it is—it's worth considering why the company ultimately sided with Intel over AMD.

First, it should be no surprise that Apple experiments with processors from other sources besides Intel. It just makes good engineering and business sense to consider and test alternatives. Apple even reportedly has MacBook Air prototypes with ARM-based processors somewhere inside its Cupertino headquarters, so the fact that an alternate x86 prototype exists is really no revelation.

What may be surprising is that a MacBook Air based on Llano was apparently Apple's "plan A," according to SemiAccurate's sources. However, that plan was allegedly scrapped sometime in the spring due to AMD's inability to ship processors in volume. "Binned lower voltage premium versions are probably... rare enough that Apple would probably have been severely constrained on supply," SemiAccurate wrote.

That's no doubt an important reason for Apple to take a pass on Llano, but it's certainly not the only reason. Early benchmarks revealed that Llano was a champ at keeping power use down—certainly a quality that Apple wanted for the Air. Llano also offers GPU performance that easily spanks Intel's integrated HD3000. But Llano's CPU performance doesn't compare to Sandy Bridge, and its GPU is hampered by a lack of direct access to high-speed RAM.

Assuming AMD could have delivered on the quantities that Apple expected, Apple would have been stuck with so-so CPU performance and decent GPU performance. That is, in fact, the same basic compromise Apple made for the 2010 MacBook Air, pairing older Core 2 Duo CPUs with NVIDIA's GeForce 320M controller with integrated GPU.

While that package, combined with a reasonably fast SSD, made for an overall useful machine, lackluster CPU performance was its top criticism. Sticking with AMD would have left Apple in the exact same position: great graphics, so-so overall performance. Gamers may have been happy, but then again, how many gamers are buying MacBook Airs?

Instead, Apple opted for Intel's Sandy Bridge processors. The integrated HD3000 GPU is no powerhouse—in gaming performance, in particular, it's actually not quite as good as the GPU in the NVIDIA 320M. But for the majority of tasks, graphics performance stayed steady while CPU performance crept up several notches. Essentially, the move made the MacBook Air a great machine for general use, decent for mobile media and content creation, and barely useable for high-end gaming.

Sticking with Intel also means Apple is ready to benefit from the chipmaker's next-generation Ivy Bridge processors slated for next year. Ivy Bridge will combine several GPU improvements, including OpenCL compatibility and updated OpenGL support, with Intel's highly efficient 22nm tri-gate transistor design. This will allow Apple to both improve performance while cutting power drain and likely increasing the MacBook Air's already impressive battery life.

In the end, the choice Apple made looks like the right one. The MacBook Air now accounts for nearly one-third of Apple's notebook sales, and Intel has spurred Windows PC vendors to create their own MacBook Air clones (with limited success, so far). AMD may be able to improve on Llano's performance with some design tweaks, and its GPU performance will handily beat Intel's, but for the time being it will remain a step or two behind Intel in terms of CPU performance. Having moved forward in that regard with Sandy Bridge, we don't expect Apple to go back anytime soon.

Rumor: Galaxy Nexus U.S. Launch is December 8?

Galaxy Nexus December 8 Release?
So what's the big deal about the Galaxy Nexus, anyway? First off, there's Ice Cream Sandwich, an OS upgrade that PCMag mobile analyst Sascha Segan describes as such: "Google has finally grown up. Ice Cream Sandwich is an elegant, futuristic-looking OS that borrows visual elements from both Gingerbread and Honeycomb." And, to paraphrase Segan, it's one of the biggest Android updates (14 pages of changes and counting!) that Google's made within the operating system's lifecycle.  For more on the Galaxy Nexus – to perhaps wet your whistle as you wait for its alleged December 8 launch – check out PCMag's full hands-on observations of the smartphone and its souped-up operating system.

And then there's the smartphone's hardware itself. A 1,280-by-720, 4.65-inch Super AMOLED Plus screen sits on top of the 0.35-inch thick smartphone. Tucked inside is a dual-core, 1.2-GHz processor and either 16 or 32 gigabytes of onboard storage. The Galaxy Nexus supports NFC (but not Google Wallet, a feature currently exclusive to Sprint's Nexus 4G), LTE or HSPA+ networks, and comes with two cameras built-in: a front-facing 1.3-megapixel camera and a rear-facing 5-megapixel camera.For more from David, subscribe to him on Facebook: David Murphy. Had we a nickel every time someone projected a U.S. launch date for Samsung's much-anticipated Galaxy Nexus smartphone. We've all seen it. We've read about it. We've watched the phone's international release come and go. So when's the big U.S. release, anyway?

Rumors have suggested everything from Black Friday, to Cyber Monday, to just about any November date under the sun for the launch of Samsung's first big Ice Cream Sandwich device (that's Android 4.0, the latest iteration of Google's mobile operating system). The Android website Droid Life is the latest gossiper to jump into the fray, only it's coming armed with evidence that suggests the Galaxy Nexus launch isn't arriving in November after all: Rather, December 8.

The source of the info is unknown, but the allegedly internal documents list a "Launch / End date" for the Samsung Galaxy Nexus as December 8. Although an accompanying description seems to indicate that the date could be reserved for a marking campaign for the device, instead of the smartphone's actual release date, Droid Life has corroborated its first leaked image with a second.

On this, the details are a bit more explicit: "The Samsung Nexus is now scheduled to launch in all locations on Thursday, 12/8," it reads. The description goes on to discuss Galaxy Nexus accessories that "have begun to ship to stores this week," which matches some of the rumormongering from last week that Galaxy Nexus accessories were beginning to pop up in Verizon stores and on Samsung's site.

In other words, the timing seems correct – now it just remains to be seen whether other third-party information can match up with the suggested December launch.

Week in Apple: Steve Jobs bio review, iTunes Match, and iOS 5.0.1

Week in Apple: Steve Jobs bio review, iTunes Match, and iOS 5.0.1
Why did Steve Jobs cry so much? What's the deal with the iOS 5.0.1 update? How does iTunes Match work? How did Siri's protocol get reverse-engineered? These questions and more were all answered in our most popular Apple posts of the week. If you need to catch up, you're in the right place.

Why Steve Jobs cried: Jobs cried over everything from the length of the Apple II's warranty to the iMac's CD drive to the famous "1984" TV ad. What do the tears tell us about the man?

Apple launches iTunes Match: music hoarders need not apply: iTunes Match is now available to sync your entire iTunes library to iCloud for $25 a year. If you have more than 25,000 tracks, though, you're currently out of luck.

iTunes Match: your questions answered: Apple's iTunes Match has launched, but the $25/year service isn't as straightforward as it might seem. We dug around to find answers to some of the most common questions.

iOS 5.0.1 update causing contact, WiFi headaches for some users (Updated): Apple's first update to iOS 5, designed to fix a few bugs, may have introduced a handful of new ones.
Mac OS X has its own sandbox security hole: Mac OS X appears to have at least one potential security flaw in its current implementation, and researchers are criticizing Apple for essentially ignoring the problem.

How Applidium reverse engineered Siri's protocol: A mobile application development firm has reverse engineered the underlying network protocol used for SIri's speech recognition capabilities. We take a look at how it was done and what it could mean for third-party Siri client implementations.

Hands on with the iPhone Micro USB plug and third-party chargers: Apple's European Micro USB adapter lets the iPhone charge from any Micro USB charger. So, we decided to test how fast it could charge an iPhone 4 using various chargers, and here are the results.

Unlocked iPhone 4S now for sale as Sprint locks down its own iPhones: If you've been waiting for the unlocked iPhone 4S to be available from Apple's online store, today's your day. Meanwhile, Sprint appears to be making good on its promise to begin SIM-locking the iPhones it sells.

Apple now replacing original iPod nanos due to overheating batteries: Apple has already agreed to replace overheating iPod nanos in Japan and Korea, but now its replacement program is being extended to cover the rest of us too. If you're a first-generation iPod nano owner, you may want to apply for a replacement.

Steve Jobs wanted iPhone on its own network, carrier-free: When Steve Jobs first dreamed up the iPhone with his team at Apple, he didn't want it to run on AT&T's network. He wanted to create his own network.

Have a great weekend everyone!

Week in tech: Amazon kindles a Fire (just don't call it a "tablet")

Week in tech: Amazon kindles a Fire (just don't call it a "tablet")
With the holidays approaching, tech news has been heating up. This week, we reviewed the Kindle Fire from Amazon and covered the important Stop Online Piracy Act hearings in Congress. But because this is Ars, we also ripped out a personal Web server and replaced it with something faster.
Here's the week's top tech news:

Don't call it a tablet: the Kindle Fire reviewed: The Kindle Fire has landed, and several of Amazon's promises have gone unfulfilled. But it's not bad so long as you keep repeating this mantra: the Kindle Fire is not a tablet.

A faster Web server: ripping out Apache for Nginx: Sometimes Apache can be overkill. Here's one man's tale of replacing his Apache install with a lightweight speed demon of a Web server called Nginx.
Kindle Fire first impressions: The Amazon Kindle Fire has arrived at the Ars Orbiting HQ, and so begins our intense media browsing, downloading, and consuming journey.

At Web censorship hearing, Congress guns for "pro-pirate" Google: The Stop Online Piracy Act (SOPA) had its first House hearing today, one arranged around a key goal: whacking Google and anyone else who objects to "common sense" Internet censorship.

Google releases Android 4 source code, but true openness still elusive: Google has announced that it is publishing the source code of Android 4.0, codenamed Ice Cream Sandwich. The code drop will also include the Honeycomb source history.

4chan hit by DDoS attack, struggling to get back online: The website 4chan was taken offline Sunday by a distributed denial-of-service attack, and the team behind 4chan is still struggling to get back online. 4chan was also hit by DDoS attacks almost a year ago.
It's official: America a land of young, casual pirates: 70 percent of young Americans have pirated content, but many are changing their ways in response to better legal offerings, and almost none are hardcore infringers.

Clickjack attacks plaguing Facebook with 4chan-like porn, violent imagery: A social engineering attack is spreading offensive images—including photoshopped images of Justin Beiber in compromising positions.

RIAA wants ReDigi out of the business of selling "used" iTunes tracks: A company that bills itself as "the world's first online marketplace for used digital music" just got a cease-and-desist letter from the Recording Industry Association of America.

Google opens music download store, welcomes artists to upload directly: Google Music is now open to the public and its streaming features will remain free. But that's not all: Google has also decided to begin selling music downloads directly to customers, and will even let artists upload their own content, bypassing music labels.

AMD-powered MacBook Air, a tantalizing might-have-been


MacBook might-have-been

Share This article

It’s standard operating procedure for major OEMs to keep hardware on hand from a number of suppliers — Dell, for example, readily admitted to testing AMD CPUs for years before it actually offered any for sale. It’s therefore unsurprising to hear that Apple gave AMD’s Llano a test drive as a potential MacBook Air solution — but apparently Sunnyvale came much closer to winning Apple’s business than anyone might think.

According to SemiAccurate, Apple had a Llano-based design it intended to mass produce. AMD, however, was unable to guarantee a sufficiently large supply of processors due to ongoing yield problems at GlobalFoundries. Those issues have not yet been resolved. GloFo’s yields have steadily improved throughout 2011, but AMD’s volumes are still supply constrained.

In retrospect, Apple’s decision to go with Sandy Bridge over Llano was almost certainly the right one. Even if Sunnyvale could’ve met Apple’s product needs, it probably couldn’t have done so without shafting everyone else in the process. We’ve already heard rumors that the company’s OEM customers are unhappy with its ability meet previous product commitments, and it wouldn’t have been wise for Sunnyvale to burn all its bridges in favor of throwing in with Apple.

There’s another possible reason Apple may not have wanted to go the AMD route, though it hasn’t gotten much attention. There haven’t been many reviews on AMD’s new, Bulldozer-derived quad-core FX-4100 part — and for good reason. As LegitReviews demonstrates, the 3.6GHz FX-4100 CPU’s performance is terrible when compared against existing A6 and A8 Llanos. Bulldozer chips take a natural 15-20 percent performance penalty compared to previous AMD processors, and the FX-4100 only has a 100MHz Turbo Core envelope. As a result, the 3.6GHz FX-4100 is regularly matched by the 2.6GHz A6-3650 and soundly beaten by the 3.7GHz Phenom II X4 980 BE.
Bulldozer roadmap
This has serious implications for Trinity, particularly since AMD can’t lean on a high-TDP Turbo Core frequency when building mobile parts. The existing FX-4100 draws less power than the X4 980 BE, but not nearly enough to compensate for its dramatically weaker performance.

Compare the FX-4100′s numbers against AMD’s published expectations for the future of BD processors and it’s clear that just matching Llano’s performance per watt will be a major accomplishment by the time Trinity rolls around. Everything we’ve heard thus far regarding Trinity suggests that the GPU and CPU-GPU interconnect will both be significantly improved, and as a result, AMD may be able to get by with holding CPU performance essentially static — particularly given how much of an improvement Trinity would be over Bulldozer just to hit such targets.

Two out of three, as the saying goes, ain’t bad. It’s probably enough to maintain AMD’s graphics performance advantage over Ivy Bridge. But it’s not surprising that Apple, who undoubtedly got a full preview of both Bulldozer and Trinity, would choose to go elsewhere.
