1) I BOUGHT THIS PHONE BECAUSE IT HAVE BUNCH OF NEW FEATURES AND SO MANY THINGS U CAN ACTUALLY DO WITH THIS MOBILE .
CAMERA QUALITY IS ACTUALLY THE BEST 12 MEGAPIXEL CAMERA WITH LOW LIGHT SUPERPOWER
BRIEF DESCRIPTION OF MOBILE: It features 5.1-inch Quad HD Super AMOLED screen, Qualcomm's most powerful Snapdragon 820 system chip under the hood and a brand new 12-megapixel camera with low light superpowers. All of that runs on a new edition of TouchWiz on top of Android 6 Marshmallow. And yes, the microSD card slot is back: you can use a card of up to 200GB onf the S7. The Galaxy S7 also has a very large, 3000mAh battery and it adds IP68 water resistance.
2) It has the latest snapdragon 820 processor .
3)Design:
Admittedly, my first impressions of the Galaxy S7 weren't great, as my review sample had fine scratches in numerous places on the display and the fingerprint sensor. The back was in better condition, but its glass-plated rear is an absolute magnet for fingerprints, so it never looks quite as new and pristine as you'd ideally want it to be. As a result, you'll probably want to invest in a case, particularly when the S7's rounded back and edges feel like they're constantly about to slip out of your hand.
Otherwise, the rest of the S7's design improvements are all relatively minor. The S7's metal frame is now slightly smoother and less angular, but it's also a fraction fatter and heavier than the S6's, measuring 7.9mm thick compared to the S6's 6.8mm and weighing 152g rather than 132g. However, it's not something you'd notice in everyday use.
More obvious is the S7's newly streamlined camera bump, as it now protrudes by just 0.46mm, making it far less prominent and the phone far more stable to use when sat on a flat surface. The phone still rocks from side to side a bit when tapping the top half of the screen at the side, but it's a huge improvement on the unstable S6, especially if you're using a wireless charging pad.
Another welcome addition is the S7's microSD slot, which lets you expand either your 32GB or 64GB of onboard storage by up to 200GB. This makes it a lot more flexible than the S6, and it also means you won't have to shell out for an expensive, high capacity model in order to store all your music, for instance.
One of the most important changes, however, is one you can't see at all, as the S7's IP68 certification means it now has that all-important waterproofing protection that the S6 was severely lacking. This means that it can survive being submerged in up to 1.5m of water for 30 minutes, and as the waterproof design is integral to the phone, there's no need for rubber caps to block off the phone's ports if you accidentally drop it down the loo or into a puddle.
The only major quibble I have with the S7's design – apart from its overall slipperiness – is its fingerprint sensor. Having grown used to rear-facing fingerprint sensors, such as the one on the Nexus 6P, the S7's seems positively old-fashioned by comparison.
4) Display:
Samsung's Super AMOLED displays have always been one of the highlights of its S-series smartphones, and the S7's screen is no exception. It might not have the curved sides of the S7 Edge, but this 5.1in 2,560x1,440 resolution display has a super sharp pixel density of 577ppi and its quality is top notch. Covering a full 100% of the sRGB colour gamut, it can produce pitch perfect 0.00cd/m2 blacks and a super-high contrast ratio makes it lovely to look at, regardless of whether you're watching a video or scrolling through web pages.
With a peak brightness of 353.74cd.m2, it's not as bright as most LCD-based smartphones, but switch to Auto brightness and shine a torch on its adaptive light sensor and the brightness will shoot up to around 470cd/m2. It's the same thing Samsung did with the S6, and it makes using the S7 in bright sunshine much easier than some of its other Super AMOLED handsets. It also has the added benefit of Samsung's Always on Display technology, which can be used to display information such as the date, time and the phone's battery status when the screen is turned off. It's a similar idea to Motorola's Moto Display, which displays the time and any notifications when you pick up the phone or give it a jolt, but, as its name implies, the S7 displays this information permanently, which is more useful when you just want to glance down at your phone on the table to check the time.
The Always on Display can also show calendar information, but it's a shame this widget isn't actionable like traditional Android Marshmallow notifications. It's also not particularly useful for anything other than just looking at the date, as it doesn't pull in any events from Samsung's S Planner app, which is in turn linked to your Google Calendar, or highlight upcoming appointments.
Samsung's promised that the Always on Display won't detract much from the phone's battery life, using less than 1% of battery consumption per hour when it's enabled. This is because its Super AMOLED screen will only illuminate the pixels it needs in order to show the information. As a result, only a fraction of the display is being used at any one time. We didn't see any significant battery drain in our time with the handset to date.
5) Performance and gaming:
There's been a lot of hype and hoo-hah about which processor Samsung would decide to put in the S7, as early rumours hinted that it might return to using Qualcomm's chips. And it has in some territories, opting for the brand-new Snapdragon 820, but the UK and Europe have got Samsung's own octa-core Exynos 8890 processors instead.
This is made up of two quad-core chips running at 2.3GHz and 1.6GHz respectively, the former handles more intensive tasks while the latter provides superior power efficiency. In my initial testing, it seemed like we'd drawn the short straw in this regard, as my Geekbench 3 scores only reached 1,353 in the single core test and 4,794 in the multicore test, which isn't really that much better than the S6's respective scores of 1,427 and 4,501.
However, when I re-ran the tests later in the day, these scores shot up to 2,115 and 6,437, putting its multicore score way out in front of the Snapdragon 820 results I recorded at a special benchmarking event earlier in the year. Here, the Snapdragon 820 scored 2,356 and 5,450, placing it in roughly the same ballpark as Samsung's Exynos chip.
Regardless of which way you look at it, though, the S7 is easily one of the slickest and most responsive phones I've ever used. Samsung's Marshmallow version of its TouchWiz interface simply flew underneath my fingers, and apps loaded almost instantly.
Web browsing was similarly quick, reaching an impressive 1,882 in Peacekeeper. Media-heavy websites like the Guardian were lovely and smooth, and it coped with scrolling images, ads and comments sections beautifully.
The Exynos 8890's graphics capabilities are equally impressive, although here the Snapdragon 820 seems to pull ahead. In the offscreen Manhattan test of GFX Bench GL 3.0, for instance, the S7 managed a 2,336 frames(around 38fps), but the Snapdragon 820 dev kit I tested produced an even smoother 2,860 frames(around 46fps). The S7 also couldn't quite match the Snapdragon 820 on more intensive graphics tests either, as GFX Bench's offscreen Car Chase test finished in 886 frames on the S7(15fps) but 1,049(18fps) on the Snapdragon 820.
In practice, though, there aren't many apps which require this much graphical horsepower, so you're unlikely to notice any discernible difference in speed in your average gaming session. Even demanding games like Hearthstone ran perfectly fine during our testing, so simpler games like Threes and Candy Crush should prove no problem at all.
6) Android 6.0 and TouchWiz:
Samsung has been dragging its heels on rolling out Android 6.0 Marshmallow to its current crop of Galaxy smartphones – the Galaxy S6 only just received an OTA update this week for Marshmallow – but the S7 is the first one to come with Android 6.0 straight out of the box.
Of course, Samsung uses its own TouchWiz interface rather than plain Android like Google's Nexus 5X or Nexus 6P, so it looks a little different to the Marshmallow you might be used to seeing. Ultimately, though, Samsung hasn't made many radical changes to TouchWiz for Android Marshmallow, as the overall look and design is practically the same as its Lollipop-based TouchWiz.
The only major difference is the design of the notification menu, which now has an expandable shortcut button menu as well as a scrolling bar across the top of the screen, and a new Quick Connect bar which lets you connect your phone more easily with other devices, such as your TV, Bluetooth headphones and other mobile devices.
Once you've selected a device in the Quick Connect menu, you can use share photos, videos, audio files, as well as app information from Memo, S Planner, Contacts and My Files if you're connecting to another phone or tablet.
7) Camera:
The camera is one of the most important parts of any smartphone, with less-and-less of us choosing to carry a seperate snapper. The Galaxy S6 had an excellent camera, but with the S7, Samsung's actually taken a risk in order to improve image quality further still. It's done this by reducing the camera's resolution to 12-megapixels instead of sticking with the S6's 16-megapixel sensor.
That might sound like a step backward, but Samsung's made each individual pixel bigger, increasing their size from 1.12um on the S6 to 1.4um on the S7. The bigger the pixel, the more light it gets, thereby helping to reduce the amount of noise in your pictures. The aperture of the lens has also been widened to f/1.7, meaning that 25% more light reaches the sensor than on the S6. Add in Samsung's new dual-pixel sensor, which provides 100% phase detection pixels for super-fast autofocus, and the S7 should produce higher quality pictures than its predecessor - which it does.
In our outdoor photos, there was certainly a lot of detail present, as even far-off street signs and building brick detail on the outskirts of the frame were sharp. There's plenty of contrast available, too, and colours were lovely and bright(both on the phone and on our colour-calibrated test monitor). It tends toward a slight overexposure in shots with a challenging dynamic range, which for most is preferable to the alternative of darker shots, plus I was able to rectify this by switching to HDR mode when possible.
Compared to the S6's camera, our outdoor shots weren't that different. Colours were richer on the S6, though not more realistic, but otherwise there's very little in it apart from the obvious difference in aspect ratio. The S7's sensor is a more traditional and sqaurer 4:3 ratio at the full 12-megapixels rather than the widescreen, and screen-filling, 16:9 ratio used on the S6.
Indoors, it was a similar situation, at least on the surface. In both our low light, flash and bright light tests, both phones produced nigh on identical shots. However, it was only when I delved into the shutter speed information did the S7 reveal itself as the superior smartphone. For instance, in our low-light shot, the S7 took the photo at 1/25 sec, whereas the S6 shot at 1/15 sec. This means the S7 will be more reliable in low light situations and less likely to blur moving subjects, making it the better camera overall.
8) Conclusion:
I find it bit expensive, but still its up to the buyers.
