As recently as the Galaxy S5, Samsung had a fundamentally different strategy from companies like HTC and Apple. While design wasn’t ignored completely, Samsung Mobile had a different set of priorities. In general, it felt like Samsung wanted the phone to have every feature possible to please every possible potential customer. Features like a removable battery and microSD card slot seemed to be a crucial point of differentiation. TouchWiz focused on delivering a full suite of applications even if they were pretty much redundant when compared to Google’s applications. Samsung also seemed to cost-optimize their external shells, favoring polymer builds over glass or aluminum. Since the Galaxy S, this strategy paid off handsomely. With the help of strong marketing, Samsung proceeded to dominate the Android market from the days of the Galaxy S2, to the point that almost no other Android OEM was relevant in terms of market share.

However, Samsung’s tried and true strategy failed with the Galaxy S5. Fundamentally, Samsung had always been competing with Apple and their iPhone line-up at the high end, but Samsung consistently held a price advantage. The real problem was the rise of low-cost flagship phones, which squeezed Samsung significantly. Other OEMs were able to justify their high-end pricing by delivering a polished software experience and premium hardware design. In comparison to these relatively cheap phones which delivered largely the same experience and hardware, Samsung’s sales crumbled and the Galaxy S5 didn’t meet sales expectations.

This brings us to the Galaxy S6, which is supposed to be Samsung’s attempt at refocusing their product design and lineup. Design has become a major priority, and the Galaxy S6 is a radical departure from previous design in terms of almost every design choice. The Galaxy S6 represents the best that Samsung can make to some extent, as a great deal of the phone is composed of Samsung-made parts to achieve maximum vertical integration as seen in the specs below.

Design

There’s a lot of ground to cover in the Galaxy S6 and S6 edge, but probably the most immediate change is to the design. The Galaxy S6 is a unibody design, with no apparent screws. This does mean that there’s no removable battery or microSD slot, which shouldn’t be a problem for most people although this may be enough for some to write off this phone completely.

The back cover is now glass instead of plastic, and is attached to the phone with glue instead of plastic latches. Regardless of color or model, Samsung has placed an extremely fine pattern beneath the glass that manages to be subtle but also surprisingly brilliant under direct light. It’s tasteful in a way that the Galaxy S5 and Note 4 weren’t. The back of the phone also has a single LED flash, a heart rate monitor, and the camera which bulges out significantly. I personally don’t have a problem with camera humps, but the Galaxy S6’s camera hump is probably the biggest I’ve seen in recent memory.

The glass back cover meets the metal frame of the phone, which provides most of the structural rigidity and strength. On the normal Galaxy S6, this frame has a very slight curve and is almost cylindrical along the top and bottom of the phone, but flattens out along the sides for better grip. The bottom of this frame has the speaker, microUSB port, and 3.5mm headphone jack, which does make for some resemblance with Apple products launched within the last year. At any rate, the placement of the speaker, USB port, and 3.5mm jack are all appropriate for a phone.

The left side of the frame contains the volume buttons, which are clicky and solid, although pressing the buttons off-center does produce a noticeable flex. The right side of the frame has the power button and the nanoSIM slot on the normal version.

On the edge variant, the sides of the frame are dramatically thinner and appear to be angled out when compared to the Galaxy S6. In the hand, this makes it feel much thinner than the S6, but it really feels almost too thin to hold comfortably. Combined with the flat back, it’s really a bit of a struggle to pick up the edge off of a table, which compromises usability when compared to the normal S6.

The top of the frame contains the IR LED for TV capabilities and a hole for a microphone. On the edge variant, the nanoSIM slot is relocated to the top of the phone.

The front of the phone is probably the only aspect of the design that feels relatively similar to the Galaxy S5. However, the texture of the bezel beneath the glass is similar to the subtle finish of the back cover, which makes for a unique visual effect that manages to be tasteful and quite unique. Other than this, we see the same layout as most Galaxy phones, with two capacitive buttons (multitasking on the left, back button on the right) and a physical home button. In the case of the Galaxy S6, this home button has been turned into a fingerprint scanner that is touch-based rather than a swipe sensor. Along the top of the front face, we also see the ambient light sensor, a proximity sensor, the earpiece, and the 5MP front-facing camera. Directly below these items is the display driver beneath the bezel, which is similar to the “logo bar” of the One M7, M8, and every other phone on the market today. On the S6 edge, the sides of the display are curved to reduce the width of the phone, which does make it easier to hold in the hand, but there’s really no bezel reduction here as the side bezels seem to be larger than what we see on the S6.

Overall, the design of the Galaxy S6 and S6 edge is really unlike anything else they’ve produced in recent memory. The phone itself is well-sized and feels much more ergonomic than the Galaxy S5 due to the thinner build and mildly reduced bezel size. It really feels like Samsung cared about the design of the phone this generation, and the attention to detail here immediately puts Samsung near the top in this area. The front of the phone still feels a bit derivative, but I suspect that there isn’t much Samsung can do to change this when faced with design constraints like a physical home button. The S6 edge does look better in some ways, but ergonomically the sharper and thinner edge is a compromise compared to the normal S6. Either phone is still easily one of the best-designed phones I’ve seen this year.

    Glad that anandtech FINALLY included the browser benchmarks using sammy's stock browser.
  • lilmoe - Friday, April 17, 2015 - link

    It's an improvement. But still, "browser benchmarks" are just that; a benchmark to software side of the browser engine. It's only good for testing CPU performance when we're ONLY looking at generation improvements of the *same* platform/browser/OS.

    I wish we had a more "open"/transparent cross platform benchmarking suite... Anyway, it looks Exynos is truly back as a market leader, as in being a generation above everything else. I'd expect it to stay in lead well till the Note 5 is here.

    "Although the dynamic range of the Galaxy S6’s IMX240 sensor is inherently lower than an equivalent 1.5 micron pixel-size sensor due to the nature of CMOS image sensors"

    This is not true. Pixel size rarely affects daylight dynamic range of the sensor. D800 series (36MP FF sensor) has actually tiny bit wider dynamic range than 12MP FF sensor of A7s.
  • Alien959 - Friday, April 17, 2015 - link

    Yes, that's true for dslr's because they still have large enough pixel size so dynamic range isn't affected. Even d800 have many times larger pixel photo sensor than 1.5 micron used in SG6. For bigger densities in smaller sensors dynamic range is lower compare some high end compact like panasonic LX7 and cheap point and shoot.

    Various review sites direct comparison between phone cameras and Note 4/GS6 actually had LESS highlight clipping than iPhone 6.
  • Alien959 - Friday, April 17, 2015 - link

    Yes, I have read some of the so maybe sony definitely improved the sensor so samsung is using that versus their own. Different generation sensor and processing also affect the final image.

    It's a very hindsight-heavy negative view of the s5 in this review. I'm surprised sales weren't great for it as it fixed most of the issues with the s4's performance and camera.

    Losing waterproofing, removable battery and SD card are killers for me but apart from that I don't see what makes the s6 a brilliant. The improved software performance will hopefully be brought down to older devices, the improvements in SOC design and battery efficiency are offset by the pointless resolution increase, and the mantra "must follow apple's cue to be considered premium" isn't convincing.

    Switching to white backgrounds for apps wastes the advantage of AMOLED as well.

    Still, it's selling well so I doubt Samsung care.
  • lilmoe - Friday, April 17, 2015 - link

    The GS5 didn't sell well because of "perception", not merit. It was a HUGE upgrade over the GS4 in almost every aspect IMHO. I'm one of those who actually liked the "band-aid" plastic back. I would have preferred if Samsung made the GS6 closer to the Alpha's design; metal frame with plastic back, but less squarish (IE: the same exact shape/corners of the GS6 but with the same plastic back as the Alpha).

    I believe that Samsung nailed the design with the Alpha and Note 4, but it seems that reviewers and consumers didn't agree. That stupid twisting of the back cover by reviewers to prove that it was "flimsy" only proved that they were completely ignorant of the quality of materials and the functionality/practicality it entails.
  • Ammaross - Friday, April 17, 2015 - link

    Yep. It's the reviewers that forced Samsung's hand into copying the metal+glass design that the iPhone has. Personally, I think it's horrible as the S6's glass back makes it far too slippery in-hand. I'm definitely putting a bumper on it just so I can hold on to it (which of course entirely defeats the metal+glass design anyway!). Plastic does not mean "cheap," merely flexible (in application/texture, not just robustness).
  • FlushedBubblyJock - Friday, April 17, 2015 - link

    Well, yes, I agree, the reviewers had nothing but disdain if it wasn't "the solid and simple apple industrial design that feels expensive in my hand" but add in the drooling sheep and parrots in their responses, they certainly totally contributed as well.

    Since these people function on mindless perception, not facts, we have the cloned result.
