With the basics down, the Galaxy S5 can layer on the special effects and modes. The S5 packs in the same front-and-rear camera dual-shot feature as last year's model, and most of the same filters and modes. A new one, real-time HDR, is one of those simple additions that go a long way. With it, you can toggle this on-screen control to preview the scene with HDR before you commit to the snap.

Samsung also spruced up the settings, turning a long list of toggles into a neatly arranged grid. It's here that you'll see the new selective focus setting, which lets you shift the focus of photos taken in this mode to the foreground or background.

The GS5 doesn't do away with the traditional modes menu. In fact, you'll find the new Virtual Tour mode in there -- this one cobbles together a 360-degree scene that you can share as a video or in stills. "Shot & more" consolidates five modes into one, like best photo, drama shot, and eraser mode. You choose the mode, take the picture, and choose which eligible mode you want applied. The best thing about "Shot & more" is not having to over think who you want to take your photo; though you'll still have to know you want to do something out of the ordinary.

Although Samsung did strip away a few other modes, you can still download more through the native camera app.

I like what Samsung did to clean up the camera experience, but the Galaxy S5's expanded editing tools are my favorite. Not only do they get a spiffier look, there are a lot more of them, including the ability to resize images, tweak portraits, and decorate, even annotate, pictures.

The Galaxy S5's front-facing camera gets a touch-up, too. The 2-megapixel photos automatically get the airbrush treatment through the Beauty Face mode. This time, though, a slider lets you control the intensity. Crank it up to level 5 for the full mannequin effect, or turn it off entirely -- like I did -- to go au naturel. Regardless, photos are still low-resolution and as grainy or indistinct as you'd expect. Skin tone weirdly took on a blueish hue in one shot, my most of my selfless looked about the way I expected.

Samsung has made some strong strides in the camera department, but I do have one important bone to pick. When you open the camera from a secured lock screen, which I do like being able to do, options are more limited. You can't access camera modes or selective focus. It also takes 3 seconds to load the camera app, which is faster than unlocking your phone and opening the camera from the home screen.

Performance: Speed, LTE, battery life

If performance clinches the deal for you, the Galaxy S5 is one mean speed demon. Its 2.5GHz quad-core Qualcomm Snapdragon 801 processor is at the top of its game, which reflects in both real-world and diagnostic tests. For instance, the graphics-heavy Riptide GP2 racing game was smooth, with all the surface effects and shadow lighting that sticklers for detail may notice. Navigation felt smooth and fast. Apps opened without much delay, and content loaded quickly. After using the Galaxy S5 for a week, the S4 definitely felt a tick slower.

Diagnostically, the Quadrant benchmark returned a result of 23,707, which is very, very fast. This means that apps will load quickly and smoothly and that games and videos will play back seamlessly, showing rich detail.

Compare the Galaxy S5's Quadrant score with the HTC One M8's result of 24,593. They should be similar -- the two phones use extremely similar chipsets. Now, take these numbers with a grain of salt. Samsung (and other phone manufacturers) has been accused of manipulating popular benchmark results, receiving backlash for phones like the Galaxy Note 3, which measured 23,048 in our tests.

The phone's diagnostic and real-world LTE test results also come out high. The network's strength in your area will alter your experience. For instance, rainstorms can affect radio signal -- as it did during a San Francisco storm during my test period -- taking three or four times longer to stream and download content than when it's sunny and dry. After the clear skies returned, the Galaxy S5 blazed on both T-Mobile and AT&T networks here. Although I did hit some dead zones from time to time, speeds were consistently strong, hovering around 15-to-20Mbps down for T-Mobile on the Speedtest.net app.

Upload speeds were also strong, something I noticed both using the app and uploading photos and status updates through social networks and emails.

That said, the phone's 2,800mAh ticker took my pummeling in stride. Its reserves predictably dropped the more videos I streamed -- a lot -- but didn't drain much overnight when I left it, unplugged, as my alarm. It's always tough to tell battery-life needs when you're intensely testing a new phone, which requires constant use, even during times you may ordinarily lay your phone down. How much charge the phone holds also decreases over time, much to everyone's consternation.

Even though the Galaxy S5 have and HTC One M8 have the same CPU and GPU clock speeds, the M8 scored a few points higher in each test. This could have to do with Samsung's aggressive throttling. When the CPU and GPU get too hot -- like when running a demanding game -- they automatically lower the clock speed to prevent the device from overheating.

This happened earlier during benchmarking tests -- the Galaxy S5 originally got a result of 14,000 in 3DMark (versus the HTC One M8's 20,795 score) -- but CNET editor Eric Franklin, who ran the tests, was forced to test it on an icepack to keep the S5 cool.

He also tried running the benchmarking test in the freezer for a few seconds. 18,000+ was the highest the phone would consistently get, but if you're not willing to play games with an icepack in your hands, you'll likely see lower performance than what's seen in the charts.

Still, 18,000 or even 14,000 are great scores compared to the majority of smartphones. It's just unfortunate that Samsung doesn't have a more elegant way of dealing with heating issues.

In CNET's video runtime test, the Galaxy S5 clocked an impressive 15 hours, 18 minutes of video playback before shutting down.

The Galaxy S5 has 16GB internal storage, though it's also on sale for 32GB; both variations have 2GB RAM and expansion slots that take up to 128GB in external storage.

FCC tests measured a digital SAR of 1.6 watts per kilogram.

Call quality

The Galaxy S5 came through on call quality when I tested the phone in San Francisco using T-Mobile's network. For the most part, audio was extremely clear, without background haze or interruptions.

Voices sounded natural, and loud enough when I increased the volume nearly all the way. I'd like a little more in volume reserve for those noisy situations. As with other Samsung phones, the Galaxy S5 has a digital sound-booster, but this routinely introduces aural imperfections, like buzzing and scratchiness, so I wouldn't recommend it.

On his end of the line, my longtime audio testing partner said the volume was so loud on his end, it was almost on the brink of being uncomfortable. It was, however, crystal clear and noise-free. Voice tones sounded warm and natural, and only a shade less lively than i do over a land line.

Speakerphone was a different story. When I tested it at hip level, volume immediately dropped for both my testing partner and me. His voice sounded distant and muffled even at full volume (my test partner used the term "mushy"), and the phone buzzed in my hands.

The buzzing motion and sound became stronger and more distracting when I turned on "extra volume." Even in a moderately noisy environment with ambient road noise, I found myself screaming into the phone and straining to make out my caller's words. He added that the speakerphone was a little echoey.

Versus the HTC One M8, Galaxy S4, and beyond

Though the Samsung Galaxy S5 has a heap of positive attributes and very few drawbacks, it still may not be the phone for you. Galaxy S3 owners should definitely upgrade to the S5, but if you already own a Galaxy S4, for example, I recommend that you wait. The S5 improves upon its predecessor in almost every way, but the changes are incremental, certainly too small to necessitate abandoning a perfectly good phone -- especially if you're still under contract.

Then there's the question of rivals. In the foreseeable future, the S5 will continue to face heat from Apple's iPhone 5S and the still-unannounced iPhone 6. As it long has, the debate between iOS and Android continues to hinge on what you want out of your phone. If you prefer the variety that Android brings and Samsung's everything-but-the-kitchen-sink approach to features, then the GS5 is the phone. But if you want to stay in Apple's ecosystem and favor the simplicity that iOS entails, then stick with the iPhone. Honestly, I doubt that any die-hard Apple fans will give up their iPhones for the GS5 anyway.

Rather, it's the beautiful HTC One M8 that is the Galaxy S5's most formidable competition. HTC can't outcompete Samsung's advertising behemoth, but the One M8 boasts HTC's superior craftsmanship and a graphically lush Android interface of its own. HTC's phone also blasts by the Galaxy S5's external speakers. Comparing them standing up side-by-side on full volume, the M8 did indeed sound fuller, louder, richer, and far less jangly. Drop the phones on their backs and there's no comparison. Samsung's external speaker muffles itself.

Samsung reasserts its dominance when it comes to the camera. Not only do its photos look more detailed across the board, with more natural colors, Samsung's sensor has also vastly improved low-light performance. Then there's the topic of 4K video, which the Galaxy S5 has and the HTC One M8 does not (that phone stops at 1080p HD). Images taken on automatic mode in dimly-lit situations look truer to life on the Galaxy S5 than they do on the HTC One M8, and the M8 photos, while still pleasing, tend to blow out the background. One exception may be with indoor photos. While both phones struggled here, the Galaxy S5 quality dropped the most. Stay tuned for a complete photo comparison among the Galaxy S5, HTC One M8, and iPhone 5S.

On specs alone, the Galaxy S5 has more tricks, hands-down. But when you add core hardware and Android functionality, they're evenly matched. Both superphones have 128GB external storage capacity, but the HTC One M8 gives you 32GB for about the same prices the Galaxy S5's 16GB, at least in some markets. If you don't save a ton of media on your phone, or if you already have an expansion card, HTC's memory boost may not matter to you.

At the end of the day, these phones are fairly neck-and-neck, with Samsung pulling ahead in camera quality and software capabilities, and the One M8 besting the Galaxy S5 on look, feel, and value.

So, do you buy it?

The Galaxy S5 absolutely is a premium, fast phone that I would buy and use every day. Its improvements over the Galaxy S4 are small, but they add up to a smoother experience. The phone's high-quality camera won't let you down, there are plenty of features to keep you occupied, and the display is bright and beautiful. And even though it is plastic, the water-resistant seals are an extra perk if you often head to the pool, hot tub, or beach.

If those things matter to you, or if you've always been a Galaxy phone fan, then by all means grab the Galaxy S5. And of course, if you've ordered a Gear Fit, Gear 2, or Gear 2 Neo, or you already own the original Galaxy Gear smartwatch, it's a no-brainer; it's one of the select Samsung phones that will work with these wearables.

I would, however, skip the Galaxy S5 if you like metal covering your smartphone, if you don't need every feature under the sun, or if you prefer a cleaner version of Android. Also move along if you're on a budget -- in some regions, the Galaxy S5 costs significantly more than other premium handsets.

After you buy it

The Samsung Galaxy GS5's camera is a wonderwork, combining the best in performance and features. Some features you probably haven't even bothered to use yet or maybe you didn't even know they existed.

Luckily, CNET's How-To team -- in this case, honorary member, Lynn La -- spent hours with the GS5's shooter, getting to know its every nook and cranny. We're passing that knowledge on to you with some handy tips to get the most out of the Galaxy S5's camera.

Lynn shows you how to configure your default settings, explains why (and when) to use HDR, and show you how different photos effects alter your shots. She also goes into why if you're not using elective focus, you're totally missing out.

Samsung Galaxy S5 variations

Samsung issued no fewer than five different models of Galaxy S4 in 2013, and although we may not see quite so many with the Galaxy S5, the company is well on its way to drawing out the S5 line.

There's the Galaxy S5 Active, with its physical home buttons and camouflage, red, or grey backplate. Right now it's only being sold through US carrier AT&T, but Samsung will likely branch out and eventually offer the heartier variation more globally.

Although the S5 Active has the same resistance to shock, dust, and water as the standard Galaxy S5, the Active does toughen up just a tad with its reinforced plastic corners. They're not grippy or bouncy, but they are burlier than the S5's delicate silvery rim, and far less prone to dents and gouges. (I know a little something about this from personal experience.)

Oh yes, there is one more difference, and that's the physical convenience button on the phone's side. Tap it to call up the Activity Zone, a dashboard with a barometer, compass, flashlight module, and stopwatch. The flashlight, by the way, can also emit Morse code -- and translate it for you.

With identical pricing (at least on AT&T, $200 with a new contract) and internal specs (OK, minus the fingerprint scanner) the title of "better" version is a toss-up. I personally like the physical buttons, but think Samsung could have done a better job making the Active grippy and easy to hold.

Beyond the Active, Samsung has also revisited the concept of point-and-shoot turned smartphone with the Samsung Galaxy K Zoom (the "K" references the word "camera" in German, "kamera"). But what you really need to know is that this hybrid, with its 20.7-megapixel sensor and 10x optical zoom is much more streamlined than last year's model.

Although more trimmed-down, it's still bulky and heavy, and awkward to use as a phone. On the phone side, the specs fall short of the Galaxy S5's top tier marks with a 720p resolution on its 4.8-inch display and 8GB of internal storage, which is rather small for a phone that takes such large images. Still, there's Android 4.4 KitKat and a total of six cores stuffed inside.

Play

The Galaxy K Zoom sells globally, with a £400 off-contract price tag from Samsung's online store, and AU$749 in Australia, as well as sales in other regions. Don't expect it to come to the US, though.

Will the Galaxy S5 family tree also sprout a Mini branch and a Google Play Edition that strips the phone of Samsung's TouchWiz Android layer? It's safe to say yes to both. This would be the third year we'd see a smaller, stepped-down version of the Galaxy S flagship, which typically come out a few months after the marquee device, and settle in at a mid-market price.

Unlike the Galaxy S5 Mini, which would likely line distributor shelves, the Google Play Edition is a much more niche device, and one that Google would peddle from its online Google Play store for fans of the unaltered Android OS who don't want to root their Samsung-ized phones. You tend to get more storage space to yourself that way, and the operating system updates quicker, since it doesn't have all those layers of extra software to push through.
