Initial Thoughts

With the Galaxy S6 and S6 edge Samsung claimed that they wanted to completely rethink how they designed and made smartphones. On the surface, it seems that Samsung has delivered on this promise as the Galaxy S6 and S6 edge are unlikely any other Galaxy S phone they have made previously. There is no removable battery, no microSD slot, or even a removable back cover. I would’ve liked to see a microSD slot, but I personally wouldn’t be affected by being limited to 32GB of internal storage. The removable battery issue is a bit concerning for me though, as it’s likely that disassembling this phone to replace the battery will require extensive use of a heat gun to loosen glue that may not adhere properly when reassembled. The materials are now aluminum and glass, which dramatically affect in-hand feel. I definitely like the move to the aluminum and glass design for the improved look and feel of the phone, but the use of the glass back is a bit annoying as the phones have a tendency to slide off pretty much any table. The edge variant of the phone also feels quite sharp in the hand and almost too thin to hold, but this is generally quite subjective.

Outside of design, there is a lot to talk about in the SoC and display. The Exynos 7420 SoC appears to be class-leading in performance, although there is the obvious question of power consumption that still has to be answered. Samsung’s first 14LPE SoC seems promising, although we’ve yet to validate whether big.LITTLE is more efficient than when we last tested it in the Exynos 5433. The GPU is generally quite close to the Adreno 430, with about a 10-20% advantage in performance depending upon the workload, although at the same clock speed it probably wouldn’t have any advantage. The 1440p display can also reduce performance compared to a 1080p display.

Speaking of displays, Samsung has integrated an incredible display into both versions of the Galaxy S6. I’m really blown away at how far AMOLED has come in the past few years, as the Galaxy S6 is one of the best displays we’ve tested for luminance and overall color accuracy. The only real problems I can see are color shifts with viewing angles, and white point tending to be a bit green depending upon the unit we’re looking at. There are some edge-specific issues, namely uneven luminance and odd color shifting towards green hues on white at the edge of the display. Other than this, the display of the Galaxy S6 is relatively perfect with its dark, inky blacks and amazing color.

Obviously an SoC and display aren’t the only issues to discuss in a smartphone, but given the limited time that we’ve had with the device this was all that could be tested. We hope to have our full review for both devices completed in the near future, and to be able to provide the full picture of the Galaxy S6 line at that time. Pre-orders for the US Galaxy S6 variants will begin on March 27th, and the phone will go on sale on April 10th throughout the US with 32, 64, and 128 GB SKUs in Black Sapphire, White Pearl, and Gold Platinum. The S6 edge and S6 will be available on AT&T, Sprint, T-Mobile, Verizon, and US Cellular, but on Boost Mobile, Cricket Wireless, and MetroPCS only the S6 will be available.

    no removable storage - stopped reading.
    maybe the next note will be worth a look

    The benefit is that the in-built storage would be faster and more efficient than MicroSD would be, however it's disappointing how much the price premium is for the larger 64GB/128GB models.

    Bought the sector 5 element case for a friend's birthday, about 2 months later he asked me for the reciept because the corner piece broke. I gave it to him and he contacted the company, they were not helpful at all and told him he would need to order a new piece to fix the case. He was then able to fix on his own and broke again within the first year. $140 dollars for a case should be under warranty for life, lets be honest most people have a phone for 2 years and would need a new case.

    very dissapointing cheap product waste of money...........

    Go whine somewhere else.

    very disappointing post waste of time..........

    Obviously those of you coming from an S5 or other galaxy phone with replaceable battery and microsd are miffed, but there are a lot of us that have been living without those features for a while. I haven't had those features since my Galaxy Nexus, but since then it's been the Nexus 4 and 5, and it honestly hasn't been a problem for me.

    I stream pretty much all my music, so even a 16gb nexus device has been fine. A 32gb Galaxy S6 would be plenty.

    But as a loyal Nexus user, I find myself drawn to the S6 for a couple reasons. The Nexus 6 is just flat out too big, and with nothing in the 5" range on the horizon, what is a loyal Nexus user to do?

    Couple things about the S6 have me interested. Awesome display. Awesome camera. In fact, as a Nexus faithful...having an awesome camera would be amazing, and by all accounts, this is one of the best around. Battery life also looks better than my Nexus 4 or 5, so even if it is smaller than last year, it's still a big upgrade for me.

    And really, there aren't a lot of phones to consider. HTC is out, because the camera sucks. Note 4 and Nexus 6 are too big. One plus one...bad support, bad screen. So for everyone complaining about the lack of removable battery and microsd....what exactly are you moving to?

    Why, oh why, do you still use browsers to test CPU performance???? You are just testing the efficiency and optimization of the browser. Put an old version of Chrome on your Nexus 9 and see how well it does.... and comparing any browser on an Apple device against any browser on an Android device is just plain misleading.

    Obviously it doesn't make sense as a general measure of device performance or hardware performance, but browser speed is still an interesting comparison to make, as long as it's never claimed or inferred that it measures hardware or general device performance.

    When is the full review coming out?!?!? Can't wait!

    "and the result of this is a Galaxy phone that looks unlike anything else they’ve ever released."

    I beg to differ. The S6 looks exactly like the S4 to me. I wouldn't be able to tell the difference if my life depended on it. This is not a bad thing, however. Once a form factor is sufficiently refined, there shouldn't be any radical changes to the essential design. After all, human anatomy is the target, and human anatomy doesn't change over years or decades, so why should the product's essential egonomics, once they're pretty well perfect? Our ears, hands, and eyes aren't going to get bigger or smaller, so once the product is optimized for most people's ears, hands and eyes, radical changes to dimensions would be stupid, especially if you hope to be able to use the device in the same way, i.e. to be able to show others what you're looking at, to use as a telephone without a wireless earpiece, have a type-able keyboard, so you don't have to shout at the phone to try to do voice recognition, etc.
