With its 5.1-inch screen but smallish top and bottom bezels, the S6 is not that much bigger than the iPhone 6. It falls right into what I personally (admittedly with largish man-hands) consider to be the sweet-spot for non-gigantic phone-size. It’s right in there with the HTC One M9 and the Nexus 5 and the new Moto X. This is Android’s new “small” and it’s pretty much what you’re stuck with unless you’re willing to do something drastic, like buy an old 2013 Moto X or hunt down a Sony Z3 Compact.

Using It

The Galaxy S6 is blisteringly fast. Switching between apps, scrolling through the multitasking queue, pulling down the notification shade, opening the camera, running games, I never once saw the slightest hitch in performance. There’s nothing wildly throw-your-hair-back about the speed; it’s not unbelievable or anything like that. Other recent flagship phones feel fast, too. But the S6 does everything you’d want it to as quickly as you could ask. And it does it consistently.
The S6 runs an Exynos processor—one of Samsung’s home-grown chips—instead of the Qualcomm’s new flagship Snapdragon 810, but it doesn’t suffer for it in the slightest. Apps launch with a snap, and even with Samsung’s historically bloated TouchWiz interface sitting on top of Android, swiping through homescreens, pulling down notification shades, and opening app drawers is quick and fluid.
To push the processor a little further, I loaded up old faithful Dead Trigger 2, which ran fantastically on the auto-detected “low” settings, and barely any worse once I manually jacked up the settings all the way to max. Similarly, GTA: San Andreas runs smoooooooth as hell, although I did see some super weird graphical glitches. So far, though, it’s the only place I’ve seen anything like that.
But all of this performance talk comes with a big ol’ asterisk. It’s great for now. Samsung’s TouchWiz interface has been getting less and less obtrusive—the newest version that runs atop Android’s latest Lollipop update is the most scaled back it’s ever been—but Samsung phones can get bad quickly. The Galaxy S5 we have banging around the office (still waiting for its fabled Lollipop update) is a shadow of its former self performance-wise, staggering under the weight of Samsung’s software plus new versions of Android. It’s impossible to predict if the S6 awaits a similar fate.
For now, though, the S6 a pleasure to use and it’s worth expressing one more time how not-terrible Samsung’s proprietary UI has gotten. In a streak of good decisions, Samsung has culled most of the extra bullshit options out of things like the camera. Once cluttered with useless toggles, it now looks simple, clean, with just the buttons you want and need. It’s practically indistinguishable from stock Android when you boot it up.
The quick notification buttons, those ones you use to toggle things like Wi-Fi and Bluetooth from the notification shade? TouchWiz gives you options to customize the ones you want, without slapping you in the face with like 50 superfluous buttons for “Golf mode” or whatever insanely extraneous bullshit it used to. All that, plus the material design ethos in Android Lollipop has bled over into TouchWiz and made it less ugly than ever. Samsung has (mostly) learned how to keep its bullshit out of your way.
And when it isn’t getting out of your way, it’s actually doing a good job of adding value. The Galaxy S6 can run apps in windows, and even run two different ones side by side, just like the Note 4, though admittedly it’s not quite as useful on a smaller screen and without a stylus. What is useful though is that a double tap of the home button will immediately bring up and open Samsung’s quick and snappy camera app, which makes the Galaxy S6 maybe the best split-second shooter I’ve ever used.
If you’re looking for a real down-and-dirty look at how the Galaxy S6 shapes up shot-for-shot against its toughest competition, you can check out our camera comparison. But that’s almost beside the point. The point is that it’s fucking fast, and in the end that’s all that really matters. The app launches fast, it focuses fast, and shoots fast in a way that makes every other phone I’ve used feel like something from the civil war. When the camera is this fast, little differences in color quality hardly matter when you catch a photo that you would have missed entirely.
