According to the testing details, the device in question uses a 1280 x 800 display and is running Android 4.2.2. The processor can run between 800 MHz and 1.6 GHz clock cycles and uses a PowerVR 533 for graphics, which fits the bill as an Intel Atom chip, possibly the newest CloverTrail+ that Intel recently announced.

So does this particular device perform? Based on the benchmarks: Quite good. Here’s a comparison of the graphics performance of the tested Galaxy Tab 3 and last year’s Galaxy Tab 2 model, for example.

And SamMobile recently noted a different benchmark test of the Tab 3 using the Antutu test, finding that the device scored the highest ever for an Android tablet in terms of overall performance.

So why would Samsung, which makes it own chips for smartphones and tablets, consider an Intel inside its newest Galaxy Tab? Samsung could be keeping the Exynos for its own handsets, such as the new Galaxy S 4, because it sells more handsets than tablets. The company’s tablets wouldn’t like suffer any performance hit by using Intel’s silicon either; at least not if the early benchmarks are valid.

If Intel’s Atom does power the Galaxy Tab 3, it would be one of the biggest mobile design wins yet for Intel. The chipmaker does power a few smartphone products, but hasn’t yet cracked the U.S. market with a top-tier hardware partner such as Samsung.

This is a big win for Spain-based Telefónica, which is trying to get as many partners as possible to plug into its BlueVia billing API. It’s previously managed to get Google, Facebook, Microsoft and BlackBerry to agree to play along, but Samsung is the first major phone manufacturer to sign up. It also happens to be the world’s top phone manufacturer, having shipped 70 million smartphones in the first quarter of this year.

Carrier billing makes it easier to sell smartphones to people, particularly in emerging markets, who lack a bank card. Telefónica has 315 million mobile customers around the world, and is particularly strong in Latin America. The fact that Google Play is already plugged into Telefónica’s billing API means that, without this deal, Samsung was risking its cardless Android customers finding it easier to buy through Google’s storefront than Samsung’s.

As Lee Epting, vice president of Samsung’s Media Solutions Centre Europe, said in a statement:

“Samsung is committed to ensuring that our customers have choice and convenience when purchasing content on our devices. Our partnership with Telefónica Digital allows us to deliver yet another easy and convenient purchasing experience to our Samsung Hub and Samsung Apps customers.”

The “direct-to-bill” option will roll out first to Telefónica’s O2 business in Germany, during the coming months, then to its other operating businesses in a phased deployment.

We’re going to be seeing more of these carrier billing arrangements in the future, and that’s a good thing for all concerned. Not only does it mean more apps and content will be sold, benefiting their producers, but it also means the telcos themselves aren’t shut out of the value chain.

And, if the carriers manage to be involved beyond the provision of basic data services, it may stop them complaining about returns on their network investments and trying to do heinous, net-neutrality-shredding things like charging content providers for their traffic. Everyone’s a winner.

The Digital Reader, which has been following this story for several months, reported Monday that an unnamed Delaware-based LLC was the new owner of Liquavista. Amazon confirmed the purchase in a statement:

“We are always looking for new technologies we may be able to incorporate into our products over the long term. The Liquavista team shares our passion for invention and is creating exciting new technologies with a lot of potential. It’s still early days, but we’re excited about the possibilities and we look forward to working with Liquavista to develop these displays.”

The purchase price was undisclosed, though it may be made public in Amazon SEC filings’s next quarter.

Amazon’s Kindle Fire tablets obviously already have color screens, but Liquavista’s technology offers the potential for color screens that wouldn’t deplete battery life to be added to e-ink readers. This would be particularly useful for children’s books and graphic novels.

• Research In Motion: future scenarios for its fate
• Tablet market to hit over 377 million units by 2016
• 2012: Data, spectrum and the race to LTE

Why? This is more a traditional camera that has integrated connectivity. The older Galaxy Camera with LTE seemed more like an Android device with camera capabilities bolted on. You won’t find Android on the NX2000, although I suspect the user interface is similar to the camera app on Samsung’s Galaxy S 4: Company representatives told me that Samsung is trying to use the same interface across phones and cameras.

Forgetting the interface and connectivity for a second, the NX2000 offers some impressive capabilities that you won’t find on a smartphone: shutter speeds up to 1/4000th of a second, a wide ISO range from 100 to 25800, and a large ASP-C sensor that is typically found on DSLRs. The NX2000 has a burst mode of 8 frames per second, which can certainly be useful, but we are starting to see high-end smartphones rival that.

Aside from taking advantage of a common user interface, Samsung is also cleverly using its own brand of Wi-Fi sharing. What used to be called AllPlay on Samsung phones and tablets is now Samsung Link. With it, you can wirelessly share photos from the NX2000 to Samsung mobile devices and smart televisions. The camera also supports the standard Wi-Fi Direct for sharing images and videos to other Wi-Fi devices. And connecting the camera to a phone or tablet should be easy with integrated NFC.

I spent a limited amount of time with the older Galaxy Camera and found the image quality to be slightly better than a smartphone, but not even that close to what I can get from a $700 DSLR. That’s the problem with grafting a point-and-shoot camera onto an Android-based Wi-Fi device: You get instant and simple connectivity but at the cost of image quality.

I suspect that won’t be the case with the NX2000, which looks like a camera with interchangeable lenses from the ground up, with the added benefits of Wi-Fi and NFC technology.

The 12-person San Francisco startup, headed by CEO Tim Tuttle, already had $2.4 million in hand from investors like Google, Greylock Partners, Bessemer Ventures and others. Tuttle refused to give the total value of the trio’s new investment except to say it exceeds all previous funding.

The backing of leading companies from the consumer device, semiconductors and telecommunications worlds is a significant endorsement of the company’s vision.

“We’re still a small company, but we have the backers and team to make a serious run at solving a very hard problem,” Tuttle said in a phone interview. “Which is, how do we get computing devices and applications to understand everything we say and find stuff before we need to search for it?”

That vision — which is shared with others working in predictive computing — is that our computers should push information to us, instead of us having to constantly ask. Expect Labs’ videoconferencing iPad app, MindMeld, is a basic example of what it’s working on: as a conversation is taking place, the contents of it are being analyzed and relevant information pops up in response to what’s being said.

Expect Labs’ three new investors seem to be positioning themselves for the future of computing that’s defined by natural interfaces: touch, gesture and voice. Samsung is one of the biggest consumer electronics makers in the world and will probably want to be able to offer natural interfaces with its TV and mobile devices one day; Intel makes sensors that will pick up inputs like voice; and Telefonica could theoretically use something like what Expect Labs is offering and turn computers listening to phone calls into an additional service for individuals and businesses.

Expect Labs’ partnership deal with Nuance Communications, signed last year, will continue, Tuttle said.

With the fresh round of capital, Tuttle says he plans to grow his team with experts in machine learning and language analysis, and scale up the company’s current infrastructure.

• 2012: Data, spectrum and the race to LTE
• CES 2012: a recap and analysis

One interesting thing about this partnership is that Samsung has its own Smart TV platform, which it has been promoting aggressively to app developers. So why get a third party to power your devices? One likely answer: Samsung’s platform has been evolving from an all-purpose app platform towards a more TV-centric approach for high-end TV sets.

At CES in January, Samsung unveiled a new UI for its 2013 Smart TVs that comes with voice control, a live TV guide and a remote control with an integrated touch pad. The company is offering owners of select 2012 TVs to upgrade to the new experience for $300 with the help of its Smart TV evolution kit; but that kind of premium pricing doesn’t really work for a $130 Blu-ray player.

In light of that disparity, Samsung has to make a choice: Either fork its Smart TV platform to work on both high-end and low-end devices, or use a different solution for lower-priced devices. It looks like the company may be ready to go for the latter — and Opera seems to be the company to benefit.

As these companies battle for the top spot, it’s interesting to note which competitors aren’t on the top five smartphone shipments list. Namely: HTC, BlackBerry and Nokia, all of which were on the list together as recently as the last quarter of 2011. Now it’s LG, Huawei and ZTE that round out the top five after Samsung and Apple.

It should be noted that Apple is the only vendor that reports sales and not shipments, but even that fact doesn’t support the idea that Apple outsold Samsung. It’s simply not a reasonable expectation that Samsung has 33.3 million smartphones sitting around in inventory worldwide.

Unless Samsung stumbles in a big way, it’s not likely that another Android handset maker will outsell Apple’s iPhone any time soon. For all intents and purposes, Samsung is the de facto Android standard, having built a huge audience with its line of Galaxy smartphones. This strategy started in 2010 and, as we pointed out in mid-2011, Samsung was poised to become the smartphone king. Let’s see how long it keeps the crown.

That’s good for power users, of course. Too many features, however, can confuse the masses, leaving people with a complicated experience. Has Samsung delivered something for everyone? I spent a week with the Galaxy S 4 to found out.

To be sure, there are more software functions in the Galaxy S 4 than any smartphone I’ve used yet. That includes the new HTC One, which is feature-packed in its own right. When Samsung launched the phone, this should have been obvious: At the launch event that I live-blogged, my fingers couldn’t keep up with the presentation. That’s because most of the innovation is in Samsung’s software, although the hardware shows improvement from last year’s phone.

Hardware

If I were to hand you a Samsung Galaxy S 4, you might actually mistake it for a Galaxy S 3. That’s not a bad thing if you liked the prior design. The phone is still mostly plastic and has a removable cover. Samsung told me that customers want the flexibility of an SD card slot and replaceable battery; the polycarbonate plastic allows for this.

The dimensions of the Galaxy S 4 are also very similar to last year’s phone. It’s actually the same length and width, but slightly thinner, and yet it has a larger display: 5-inches compared to 4.8. Still, the phone weighs 0.1 ounces less this year.

The biggest noticeable difference is the screen. Not because it’s 0.2-inches bigger, but because it’s a full-HD (1920 x 1080) display with 441 pixels per inch. The clarity is stunning, particularly for images and videos, although text is crisp as well. Samsung’s Super AMOLED technology has improved also. Colors don’t appear over-saturated as they did in prior Samsung handsets.

Samsung chose to use the same button layout on the Galaxy S 4 as it has with recent Samsung devices. As the owner of Galaxy Note 2, for example, I’m already used to the volume rocker on the right side of the phone with the power button on the right. A headphone jack and microphone input are on the top of the Galaxy S 4, while another microphone and micro USB port are on the bottom. A hardware home button and two touch areas for Menu and Back are below the screen.

A 13 megapixel camera with LED flash sits in the center of the phone’s upper back area — the front has a 2 megapixel sensor — and a speaker is at the bottom left of the back. Pulling off the removable cover provides access to the 2600 mAh battery, micro SD card slot and SIM card. The phone could potentially support wireless charging in the future but that feature hasn’t been announced for the U.S. I was able to routinely get through a full day on a single charge with the device.

Here in the U.S., Samsung is using Qualcomm’s quad-core Snapdragon 600 chip clocked to 1.9 GHz, paired with 2 GB of memory. It’s a potent combination and the handset never exhibited any lag in my testing; even with several apps running in the background. I’ll leave benchmarking to others. Suffice it to say, if there’s a faster Android phone on the market, I haven’t seen it.

There aren’t any missing connectivity options here either: Samsung has loaded the Galaxy S 4 with just about every type of radio you could want. The LTE handset includes 802.11 a/b/g/n/ac support, Bluetooth 4.0, NFC, and GPS. Files can be sent wirelessly through NFC and Wi-Fi Direct — just tap the Galaxy S 4 to another compatible phone — while media can be streamed over Wi-Fi to an HDTV. You can even play a song on multiple Galaxy S 4 handsets, using each phone as an independent speaker with Samsung’s Group Play app.

Phone calls on my Sprint review unit were clear, both in the hand and on speakerphone. I don’t live in a Sprint LTE area, so I couldn’t test that service. (Note: That could have affected my battery life tests as LTE handsets can use more power than 3G devices.) Instead, I was relegated to a much slower 3G experience. I do have an 802.11ac Wi-Fi router, however, and was able to get full wireless speeds from my home broadband, which is a 75 Mbps FiOS connection.

Software…

I can’t stress enough that while the hardware is nice, the Galaxy S 4 is chock full of software features that push the experience in a positive direction. Android 4.2.2 is the base operating system that Samsung builds its TouchWiz user interface upon.

Simply put, TouchWiz has evolved as a powerful software environment that contains so much functionality that Samsung has had to put a tabbed interface in the Settings. In fact, if you enabled all of the buttons in the Notification panel — think one-touch buttons for Wi-Fi, Sound, Bluetooth, etc. — you’d have 19 options to choose from. That’s because of the Samsung-specific features.

Rather than drone on about these, here’s a rundown of some of the major ones, along with a brief description:

• Smart stay — Using facial recognition technology, this keeps the display active while you look at it; helpful when reading or consuming content so that the screen doesn’t turn off
• Smart scroll — When the phone detects your eyes, you can tilt your head or the device to scroll. It took me a few minutes to get used to this function, but after a short while, I was able to get it working well.
• Multiwindow — Just like on my Galaxy Note 2, this lets me run two apps at one time. The choice of supported applications is limited, however.
• Screen mirroring — This lets you mirror your smartphone screen with another device, such as a television
• S Beam — A function that’s not new to Samsung phones, but can be handy. Tap your phone to another NFC handset and you can transfer files wirelessly.

I’m calling special attention to two specific features because they’re truly innovative and unique to the Galaxy S 4: Air View and Air Gesture.

If you’ve ever used a tablet with digital pen, you’ve seen an on-screen cursor when hovering the pen over the display. Air View is akin to that except no pen is needed. Instead, you simply use your finger over the screen for the same functionality. This “magic” is thanks to the Synaptics ClearPad and its “3D-Touch” feature.

Using your finger up to 2 centimeters from the screen then, you can hover over an app and drill down to see more information. Hover over a day in Samsung’s S Calendar, for example, and instead of seeing just part of your appointments, all events pop up until you move your finger. You can also use this to preview the contents of email without actually opening the mail. It’s quite handy, not to mention impressive.

Air Gestures are a related feature. When enabled, you can swipe through information simply by waving your hand over the phone. I used it extensively to navigate through my photo gallery without ever touching the phone. In Samsung’s browser, you can also swipe or scroll up and down on a web page with gestures. Since the phone uses infrared sensors for this feature, your hand can be several inches from the phone. Unfortunately, both of these features are limited to the Samsung apps with the exception of Flipboard: You can hover over a topic to see the top three stories related to it.

Samsung said it will be working with additional software partners to enable the gestures. I’d love to see Amazon get on board so I could turn the pages of my Kindle book without touching the phone.

… And more software

Also new to the Galaxy S 4 is the new Samsung Hub — a one-stop digital store for music, video content, ebooks and games. The store is nicely done and ties to a Samsung ID, similar to how Apple runs the iTunes store. Samsung Link makes it easier to share content across tablets and televisions while also acting as a cloud storage service. Story Album is another new addition: With it you can make small photo albums and order hard copies for a fee.

S Translate does exactly what you’d expect, helping to translate languages in Samsung’s communication apps; it even speaks aloud the translation. An Optical Reader app uses the camera to scan in text from a picture and smartly saves the information in the appropriate format. Snap a pic of a business card, for example, and the software creates a contact record from the data.

Samsung calls the Galaxy S 4 a “life companion” and part of the reason is a new S Health application. It’s software that tracks your exercise, weight, health goals and nutritional habits. Samsung will also be selling accessories to supplement the S Health app: Look for an optional heart rate monitor and pedometer band. The software is nice, but I think there are more robust third-party options available.

WatchOn, powered by Peel, is also included. With it you can control a television set or set top box — the phone has an IR blaster — and the content guide is quite good. It’s easy to find out what’s on television through the phone and immediately see the content.

On select Samsung televisions, the software also allows you to watch the television programming on the phone itself; handy if you have to leave the viewing area while others are watching. Don’t go too far though: The content is streamed over your local Wi-Fi network.

Camera thoughts

I’ve broken out the camera experience into a separate area because there’s so many scenes, modes and functions. Overall, I found the Galaxy S 4 camera to be quite good for both stills and HD videos in nearly every situation. Some HDR shots were marginal and low-light capture is good but not great. As an “all arounder”, most will be happy with the camera, which uses the same interface as Samsung’s digital cameras.

Aside from the standard Auto, Sports, Panorama and HDR functions, some of the modes include:

• Best photo — A quick burst of 8 photos is taken and the camera suggests which is the best. You can choose a different one if you want but the Galaxy S 4 is quite good at picking the best image.
• Best face — A 5 image burst that lets you mix and match the best face from each of the subjects, which works really well.
• Sound & shot — I don’t think I’d use this often, but it allows for a brief capture of sound to pair with an image.
• Drama — This mode is impressive. You have to hold the camera very steady to use it because it captures a moving subject. With a static background, the image shows the subject several times in the same photo. Think of capturing a diver in motion as he falls from the cliff: One picture of the cliff but the diver can be seen at various points in the dive.
• Animated photo — You can turn a standard photo into an animated .gif, controlling what part of the photo is moving.
• Eraser — Another nifty feature. The camera takes five images and then detects if anything is moving. If so, you can choose to “erase” the object in motion. That’s handy in case someone walks in front of or behind your subject. Since the camera has the image background through the five photos, you can remove objects in front of it and the camera will seamless stitch in the background. Good bye photo-bombers!
• Dual camera — This feature uses both the front and rear camera at the same time, allowing you to insert your own face into a photo. You can customize the frame around your face or move it around your photo so you don’t block the main subjects.

Too many features?

If it’s not yet clear that the Galaxy S 4 is feature packed, let me assure you: I’ve only briefly touched upon most of the major features. You’ll likely find more if you take your own look at the phone. So is this a problem to the casual phone user? Perhaps, but Samsung has an improved Easy Mode for these folks.

Easy Mode is what it sounds like: A simpler interface with larger buttons that show the most likely used apps and features. In fact, some of the advanced functions aren’t even accessible in Easy Mode. At first, I didn’t like that idea, but I’ve come around to appreciate it. Why? It gives new smartphone users a way to “graduate” to the full-featured Samsung experience without them having to buy a new Samsung phone. Many of the advanced features have useful pop-up descriptions as well; all of the camera modes have them, for example. You can always tell the phone to stop showing these once you’ve learned the functionality.

Conclusion

Would I recommend the Samsung Galaxy S 4? Yes, without hesitation. It’s speedy, runs all day on a single charge, and has a wonderful display. It also offers a removable battery and expandable memory, which not every phone does.

I’d like to see a little more innovation in the hardware design, but it’s a design that actually works well, so it’s difficult to complain about. Samsung does have an innovative cover accessory though. It’s called the S View Cover and I love it. It protects the display but has a cut-out window that shows information from the phone; you can even take a phone call without opening it.

Even though the Galaxy S 4 looks much like the model it replaces, this phone is a big step up thanks to the innovative software features and functions that Samsung has integrated. No phone is perfect for everyone, of course. I think most people, however, would be happy to have this device in their pocket.

Last year, I called the Galaxy S 3 “Android’s defining phone.” This year, I’m calling the Galaxy S 4 “Samsung’s defining phone” due to the Samsung-specific software features that differentiate this model.

Update: This post was updated at 5:04 am, April 24, to correctly state the Snapdragon chip has four cores.
