The good: The Samsung Galaxy S4 has Android 4.2.2, a fantastic camera, a powerful quad-core processor, and software solutions for just about every scenario -- including working as a TV/DVR remote. It's also comfortable in hand and has NFC, a user-replaceable battery, and a microSD storage slot.
The bad: Its screen is dimmer than competitors', its plastic design gives it a cheaper look than its rivals, and we found the Galaxy S4's power button turned on at undesirable times. Not all camera modes work as promised, and a long list of software features can quickly overwhelm and confuse.
The bottom line: Its laundry list of features require time and effort to truly master, but the Galaxy S4 is the top choice for anyone looking for a big-screen, do-everything smartphone.
With the Galaxy S4, Samsung clinches its goal of global smartphone domination. The supercharged Android 4.2 Jelly Bean device may look like a toy compared with the stunning HTC One and the dapper iPhone 5. But taken together, its blazing quad-core processor, colorful 5-inch HD screen, sharp-shooting 13-megapixel camera, and mile-high stack of software extras make the Galaxy S4 the most powerful superphone anywhere in the world.
What does the Galaxy S4 have? A better question is: what doesn't it have? There's the 1080p screen, zippy processing speeds that are ideal for gaming, and an IR blaster that can control your TV. Then there's the parade of camera tricks that cram action shots into one scene, use both front and back cameras, and film a video in slow-mo. The GS4 can harness your eyeballs to pause video, and it can answer a phone call with the wave of your hand. Unlike the HTC One and the iPhone 5, it also piles on expandable storage space and a removable battery.
It's true: most of the GS4's featurettes aren't essential -- and some aren't even very useful, like the camera's Eraser mode, which I never got to work, a subpar optical reader, and a translation tool that just duplicates what Google Translate already does. While none stands out as a must-have, cannot-possibly-live-without extra, these features do add up to a compelling testament that the Galaxy S4 is more than a step ahead of the pack.
So, if you want a lovingly crafted statement phone that barely strays from Android's core offering, then buy the HTC One, which also has double the internal storage for about the same price. But if you're looking for a superphone that surpasses all other handsets on the features front, then you'll find in this deserving all-around flagship a strong mix of extremely competent hardware and aspirational software with very few major drawbacks.
Design and build
Throughout the lifetime of Samsung's Galaxy S line, one of the biggest complaints levied against the manufacturer was -- and is -- how its plastic construction and flimsier-looking industrial design fall short compared with premium rivals from Apple and HTC.
No, Samsung sticks by plastic, and points to only a handful of Android enthusiasts who really care about vaunted materials like aluminum and glass. Yet the phone maker has also made an effort to add more "refined" touches to the Galaxy S4.
Indeed, when you compare the S3 and S4 side by side, you note a more rectangular home button, and metallic accents around the rim. The S4's 5-inch screen is taller and the bezel surrounding the display slimmer. Its volume and power/lock buttons are metallic-looking polycarbonate, and tooled to have slanted sides and a flat top. Look closely, and you'll see that the gaps around these controls are narrower, too.
The GS4's metallic spines are also reworked to be steeper and less curved than the Galaxy S3. In fact, while Samsung boasted its GS3 was inspired by nature, the GS4's straight sides seem to be inspired by the iPhone 5 or HTC One.
At 5.4 inches tall by 2.8 inches by 0.3 inch thick, the Galaxy S4 is actually 0.7 millimeter thinner than GS3, and at 4.6 ounces, it's 0.7 ounce lighter as well. Yet, the S3 and S4 generations still look so similar, you might not know the difference if you're not looking closely. When in doubt, flip the S4 over to see the new tiny black-and-silver diamond design on the black mist model, or a similar pinprick design on the white frost edition. As with the Galaxy S3's brushed-plastic backing, the newer generation is so reflective, you could use it as a makeshift mirror.
All about the screen
Let's head back to the screen for a minute. The 5-inch 1080p HD display yields a pixel density of 441ppi, which is higher than Apple's 321ppi screen and lower than the HTC One's 468ppi screen. In the end, I'm not sure how much these pixel density wars matter. The naked eye doesn't calibrate numbers, but it does understand if an image looks rich and sharp and detailed, versus dull and blurred.
Carrying on its fine tradition, the Galaxy S4's HD AMOLED display nails it with color saturation and contrast, sharply defined edges and details. Articles are easy to read, gameplay looks good, and photos and videos look terrific.
In a new display setting, Samsung attempts to correct an old complaint about certain colors, like green, looking too saturated. In the screen mode settings, you can choose to let the GS4 auto-adjust the color tone depending on what you're looking at.
There are a few other important things to note about the Galaxy S4's display besides color and sharpness. As with the GS3, this year's model is highly reflective indoors and out, and even at its full brightness, it can seem dim outside when fighting bright light.
Outdoor readability in strong sunlight is really tough; when taking photos, I very often couldn't tell that my finger covered the lens until I got back inside, a plight that ruined several pictures. Now would have been the time for Samsung to follow Nokia's lead with its excellent polarized screen filter on phones like the Nokia Lumia 920.
At least Samsung did mimic another terrific Nokia implementation, giving the S4 a sensitive screen you can navigate with a gloved hand in addition to the naked finger.
On top of possessing a sensitive screen, the Galaxy S4 is also the first commercially available device to feature the thinner, stronger Gorilla Glass 3 cover glass.
Features layout
The phone's screen is a big deal, no doubt, but in my opinion, the other most interesting new real estate lies north of its display.
A 2-megapixel front-facing camera sits in the upper-right corner, neighbored to the left by ambient light and proximity sensors. To the left of the speaker grill is the phone's IR, or infrared, sensor. There's also an LED indicator at the top left corner. This will glow or blink green, red, or blue to indicate certain activities.
Sharing the top edge with the phone's 3.5-millimeter headset jack is the Galaxy S4's brand-new IR blaster, which you'll use in conjunction with the Watch On app as a TV remote (it works!) All things being equal, I prefer how HTC integrated its IR blaster in the One's power button.
Below the screen, the home button takes you home (press), launches Samsung's S Voice app (double press), and loads up recently opened apps (hold). Press and hold the menu button to launch the Google Search app with Google Now. The back button is self-explanatory.
You'll adjust volume on the left spine, charge the phone from the bottom, and turn the phone on and off from the right spine. On the back, you'll see the 13-megapixel shooter and LED flash just below. Pry off the back cover to get to the microSD card slot, SIM card slot, and battery.
So do I like the new design? I do. Its sharper edges do make it look like a more premium device than its predecessor, but it won't ever be as eye-popping as the gorgeous HTC One or as understatedly elegant as the iPhone 5. Still, it's pleasant to look at and, in my opinion, more comfortable to hold than the other two.
The only thing I don't like is how Samsung's power/lock screen seems to easily light up the phone while it's tossed around in my purse. Over the years, this has been a constant personal annoyance, not only to find a phone turned on that I had clearly turned off, but more importantly, to see my handset's battery level low because I hadn't realized the screen was sucking it down. I'd probably prefer this button up top.
OS and interface
The Galaxy S4 proudly runs Android 4.2.2 beneath its very highly customized Touch Wiz interface. Argue the pluses and minuses of stock Android versus overlay all you want -- Touch Wiz has long looked outdated and stale (especially compared with HTC's fresh new UI,) but Samsung's pile of software lets the GS4 go places that a stock Android phone can't even dream about without rooting and mods.
Take my favorite new interface addition, for example. Samsung has bulked up its one-touch system icons in the notifications shade. Tap a new button in the upper right corner to expand the list to 15 icons you'll no longer have to dig through settings menus to find. If you press the edit button, you'll be able to drag and drop icons to reorder them. This is very cool and extremely useful for finding and toggling settings.
Menus play a huge role in the Touch Wiz ecosystem, so new users shouldn't neglect them. This is where a tremendous range of editing and advanced settings options live for apps as diverse as the home screen, the browser, the keyboard, and so on.
In an attempt to simplify the settings menu, the GS4's gets a makeover that breaks up topics into separate screens for connections, device items like the lock screen, gestures, and keyboard settings, an accounts pane, and the More category for battery, storage, and security concerns.
Keyboard options
I have a love-hate relationship with every virtual keyboard I meet. I demand grammatical and spelling accuracy, but am also apparently a sloppy typist. Punctuation always takes too long to insert and autocorrect rarely seems smart enough.
The Galaxy S4 gives you a few options. There's the standard Samsung keyboard, which lets you turn on SwiftKey Flow for tracing out words. There's also a separate Swype keyboard you can use instead.
I still became aggravated with mistakes and a slower typing flow than I wanted, but I did like the multiple Samsung keyboard options to introduce handwriting or insert images from the clipboard -- not that I can see myself using either.
Lock screen
In the Galaxy S4, the lock screen has become a more customizable place. You'll still choose if you swipe to unlock or use a passcode or face scan, and you can still add and order lock screen icons that serve as shortcuts to the camera, search, and your contacts.
Now, however, there are lock screen widget options, similar in concept to what you can get on Windows Phone, but different in execution. For example, you choose if you'd like to see the clock or a personal message on the screen, and if you'd like to swipe to open a list of favorite apps or launch the camera (I chose the camera and clock).
Getting the camera to open from the lock screen isn't all that intuitive. The trick is to swipe right to left near the top of the widget. If you swipe on the bottom half of the page, you'll go straight into the home screen.
There's also a nice new lock screen effect: Light. With Air View enabled, a point of light follows your fingertip as you hover over the display.
Easy mode
If the full Touch Wiz experience feels too confusing, Samsung is trying what others, such as Korean competitor Pantech, have done to simplify its take on Android with an easy mode.
Around in Samsung products since the Galaxy Note 2, easy mode, which you can start during the setup process or find later in the settings, replaces your home screens and reskins some critical apps (calendar, browser, contact list, and so on) to pare down the quantity of confusing options.
You'll still get access to core apps and features, even some extra camera modes. The icons and fonts enlarge across the easy-mode apps, and the browser includes a plus/minus icon for further increasing the phone's font size. The settings menu, however, remains the same, and it's easy to toggle back and forth from the "light" interface to full-on Touch Wiz.
Apps and features
Before diving into the GS4's feature list, let's just run through one of its key inner workings: how it communicates wirelessly. It goes without saying (but I'll say it anyway) that the Galaxy S4 is up-to-date in all its radios and communications. The phone supports 4G LTE here in the U.S. and in other regions.
