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.

    so the pictures go by default to internal memory - that's one red herring out with the bathwater ...

    lag and power drain - I guess android is so stupid the 1st thing it does when you touch your metal feel, is scan the sd card for desperately needed data, right ?

    yes, twin babies out with the bathwater fella - right out the window an onto the sidewalk below

    How is removing the sdcard more "iPhone-like" when Google Android Standard is no sdcard? The flagship Vanilla Android Nexus line is all sans sdcard. I think we often forget that and quickly point to Apple. Also, with increasing harddisk sizes and the ease of using a microsd to microusb adapter (see Dash Micro device), I think the sdcard argument is weak.

    Those were my gripes as well. However, as I've learned that the battery is still replaceable, and the charge is $45 for such a replacement done by Samsung, the battery issue doesn't bother me anymore. Then the storage thing — I've previously bought my share of SD cards to augment my phones. The largest card I've bought was a 64GB one, though, which was sufficient in my Note 3 to satisfy my hunger for filming 1080p60 when travelling. I just ordered the S6 128GB version on sale for the same price as the 32GB version, and it's plenty plenty plenty for my needs. I may have to unload some stuff in the evening to an external storage device if I go crazy with my filming, but that's it. Reading this review and seeing the impressive speed of the storage just makes me even happier that I finally chose this phone :)

    Nice Phone. There's nobody who won't take one if it were offered. But since we have to pay, ppl will decide on the things that set it apart from the pack. Samsung had an "edge" with SD cards and removable batteries and for some of us it will be a deciding factor. The battery, OK I'll get an extra charger for the car or office but the SD is inexcusable. This has ALWAYS been a blow against Apple and now it can be said against Samsung. I'll keep my S5 or wait.

    Samsung probably ALSO have sw installed on the phone that tells it when an SD card has been installed and the battery replaced, and is well aware that <1% of their phones ever went through either operation.
    I suspect Samsung's idea of what matters to the market is rather more accurate than your idea...
  • FlushedBubblyJock - Friday, April 24, 2015 - link

    I believe you are referring to the NSA, and thus, with no removable battery, the phone can never really be "turned off" and no removable SD means Homaleand Security and the NSA can access you and everything you've done at any time....

    So, it's truly and upgrade because you of course have nothing to hide

    Nice photos

    I have an S5 with wireless charging using original Samsung covers, so wireless charging is not N/A on the S5, but I admit it was an add-on purchase.
  • DanNeely - Friday, April 17, 2015 - link

    What is the "obvious" defect on the S6 screen picture? Is it one of the things that looks like a fingerprint smudge, the horizontal blue bar that looks like a reflection, or something that isn't obvious to me from looking at the picture?
  • nerd1 - Friday, April 17, 2015 - link

    I have a phone with exactly the same display (Galaxy S5 cat.6 model) and couldn't see any 'obvious' defects at all.
