Samsung Galaxy S7 release date and price
The Galaxy S7 release date lands on March 11, 2016 but the device can be pre-ordered now. Those who have already placed an order should find a Galaxy S7 on their doorsteps sometime today (March 8).
The Galaxy S7 price is currently set at US$699 for the 32 GB model, and it comes in a four main color variants: black, white, gold and silver. A 64 GB version is also available in some markets (though not in the US).

For comparison, the iPhone 6s 16 GB can currently be picked up unlocked for close to the same price – US$680 - US$699 – and the LG G5 will probably start at the same.
Samsung Galaxy S7 design and build quality
Outwardly, the Galaxy S7 is a minor – but in some ways very important – update to its predecessor. From the front, you could be forgiven for confusing the two devices, with similar button and sensor placements.
https://fs01.androidpit.info/userfi...ndroidPIT-Samsung-galaxy-s7-REVIEW-1-w782.jpg
Comparing the S7 to other Android phones, it’s undoubtedly more compact, featuring a 5.1-inch display, but it is also perhaps a little thicker than most at 7.9 mm (though you would never describe the device itself as thick).
Like the two-year-old Galaxy S5, the S7 is water resistant. It can survive a quick dip unscathed with IP68 certification: a feature that is also found on the Sony Xperia flagships.
https://fs02.androidpit.info/userfi...ndroidPIT-Samsung-galaxy-s7-REVIEW-2-w782.jpg
The Galaxy S7's dimensions come in at 142.4 x 69.6 x 7.9 mm and it houses an aluminum frame, with a scratch-resistant layer of Gorilla Glass 4 on the front and back.
It’s 1.1 mm thicker than its predecessor, but it's a facet of the design with a two-fold benefit. Firstly, the extra space allows for a 17.6 percent greater battery capacity. Secondly, the camera sensor is less prominent (more on that in a second).
https://fs01.androidpit.info/userfi...ndroidPIT-Samsung-galaxy-s7-REVIEW-6-w782.jpg
The rear of the Galaxy S7 is where the most visible design changes can be seen. The S7 has laterally curved glass, like that of the Galaxy Note 5, which, combined with its petite frame, provides a sumptuously snug fit in the hand.
Then there’s the aforementioned camera lens. The sensor protrudes by only 0.46 mm, which helps the device to remain flat when lying on its back. It’s barely noticeable, really, while the Galaxy S6 camera stuck out a distracting 1.7 mm from the device.
https://fs02.androidpit.info/userfi...xy-S7/AndroidPIT-Samsung-galaxy-s7-7-w782.jpg
On the front of the Galaxy S7, Samsung remains faithful to the previous design decisions. The proximity and light sensors are found on the top left of the device (next to the notification LED). Tthe loudspeaker for calls is in the center, and the front-facing camera is at the top right. Even the physical home button with fingerprint sensor, centered below the display, is identically shaped and placed as on the S6.
https://fs01.androidpit.info/userfi...xy-S7/AndroidPIT-Samsung-galaxy-s7-9-w782.jpg
The S7's differences can be understood better with the hands than with the eyes. There are a few small details that have a big impact on the overall design, and it means the S7 is nothing but a pleasure to look at and hold.
Samsung Galaxy S7 display
The Galaxy S7 features a Super AMOLED display with 1,440 x 2,560 resolution: the same specs as the S6. The screen is typical Samsung: that is to say, it’s sublime. Thanks to the QHD resolution and 5.1-inch display, a pixel density of 577 pixels-per-inch is achieved, guaranteeing great sharpness and detail.
Likewise, contrast and saturation are of the highest display standard: blacks are true and even in bright sunlight the S7 display is easily readable.
https://fs02.androidpit.info/userfi...droidPIT-Samsung-galaxy-s7-REVIEW-10-w782.jpg
Samsung has provided further optimisations on the Galaxy S7 and thanks to these, the contrast and brightness of the display can adjust depending on ambient light. In very dark conditions, you can watch this transition at work and because it automatically improves readability, it's a worthwhile addition.
Samsung Galaxy S7 special features
Always-on
Always-on displays are the “in thing” for 2016: both the S7 and LG G5 house this technology.
Always-on means a portion of the Galaxy S7 display remains permanently active. This part of the display can contain calendar information, the date and time, notifications and much more. The implementation of this feature caused concerns over the effect it would have on battery life. It’s small, but it is noticeable.
https://fs01.androidpit.info/userfi...xy-S7/AndroidPIT-Samsung-Galaxy-S7-1-w782.jpg
According to Samsung, the always-on function consumes little power because only individual pixels are activated. But I could see the effect it had on battery life, so I disabled it.
Dust and water resistant to IP68 certification
After a two-year wait, the Galaxy S series is again dust and water resistant. This time, instead of just surviving temporary immersion, the Galaxy S7 is now capable of surviving a depth of up to 1.5 meters for up to 30 minutes.
Thus, it has a better class of protection than the Galaxy S5 and far better than the Galaxy S6, which promised no protection against these elements.
During my test period, I doused the Galaxy S7 a number of times without problems. What is particularly clever is the handset’s recognition of wet connections: attempt to plug in your charging cable while a drop of water is in the USB port, and the S7 will prevent the charge to avoid short circuits.
Game Launcher and Vulkan
A brand new feature of the Galaxy S7 is Game Launcher. This software feature, unique to the Galaxy S series, acts as a home for all of your gaming activities.
Installed games are collected here and it also houses other game-related functions such as the ability to take screenshots, record gameplay videos, and post these to social networks.
https://fs02.androidpit.info/userfiles/6473453/image/neues_format/galaxy_s7_game_launcher-w782.jpg
Game Mode may be interesting for more “hardcore” gamers, as enabling this means all notifications can be disabled and all power and resources can be directed to the game in question (a feature which might become even more necessary as the S7 ages).
Since the Galaxy S7 and the Galaxy S7 Edge are among the first smartphones that the new Game API Vulkan supports, we can continue to expect more realistic graphics in Android games which will be optimized for these devices.
https://fs01.androidpit.info/userfi...AndroidPIT-Samsung-Galaxy-S7-edge-81-w782.jpg
Fingerprint sensor
The Galaxy S7 holds a fingerprint sensor within its physical home button. The S7 supports Samsung Pay, which is already available in the US and is rolling out in the UK and Australia soon. What's more, the wireless payment service currently has the edge over Android Pay, as it is compatible with existing payment terminals (to integrate with Android Pay many older terminals will need to be replaced in stores).
https://fs02.androidpit.info/userfi...ndroidPIT-Samsung-Galaxy-S7-vs-S6-13-w782.jpg
Samsung Galaxy S7 software
The Galaxy S7 runs Android 6.0.1 Marshmallow out of the box with Samsung’s TouchWiz interface. There is little in the way of pre-installed apps and what’s there is quite practical. Monthly software updates are in store for the Galaxy S7 to defend against security breaches and software errors.
In addition to the seven Samsung apps, there are five from Microsoft, as well as Facebook, WhatsApp and a selection of Google Apps. Your carrier will no doubt pre-install its own software to make network-specific adjustments for Voice over LTE support or Mobile Payments.

Samsung Galaxy S7 performance
The performance of our Galaxy S7 was very fast, but I experienced a few dropouts and crashes. Future updates will likely quash these bugs and increase overall stability.
Samsung has delivered a worthy improvement to the already extremely fast Galaxy S6; in many measurements, the Galaxy S7 is faster than every other Android devices we’ve seen in the newsroom.
The gaming performance is in the range of the Pixel C tablet, whose graphics chip was produced by the gaming performance experts at Nvidia. Combined with planned software enhancements from Vulkan, I expect a breakthrough gaming experience for the Galaxy S7, though currently there are only a few titles available based on the new technology.
The Galaxy S7 we have been using is the European version with the Exynos 8890 processor (a Qualcomm Snapdragon 820 version is available in the US and we expect similar performance numbers from it). The new top-of-the-range processor from Samsung has four plus four CPU cores and Mali-T880 graphics.
If only one or two cores are in use, they will be automatically overclocked to 2.6 GHz, which provides faster performance on most everyday tasks and the heat pipe cooling solution implemented into the S7 prevents thermal throttling in everyday life.
The internal storage is 32 GB UFS 2.0 memory. This flash memory provides the highest speeds we have seen on an Android device. With 389 MB / s read and 68 MB / s write speeds registered in Vellamo Metal, the Galaxy S7 is 2.45 and 1.39 times faster, respectively, than the (almost) equally expensive Nexus 6P.
https://fs01.androidpit.info/userfi...mat/galaxy_s7_antutu_geekbench_store-w782.jpg
In everyday life, you see this speed showcased when powering up or rebooting the device and, most noticeably, when installing and opening apps. If you’re upgrading from an older device, you will notice the difference immediately.
One weak point of the S7 is the small internal memory it comes with, as around 7 of its 32 GB of internal storage space are chewed up before you even install anything. Thankfully, this can be extended by microSD card to house music, movies, images and even entire apps. Despite this, it does not house the true Adoptable Storage functionality that Marshmallow provides.
https://fs02.androidpit.info/userfiles/6473453/image/neues_format/galaxy_s7_vellamo_score-w782.jpg
The device we tested crashed once in five days, and another time the TouchWiz user interface had to restart. As Samsung delivers monthly security updates, early patches should improve the already impressive stability.
In addition to the two processors previously reported, we now have reports that two more chipset versions of the Galaxy S7 are currently in the works. In Geekbench's database, a smartphone called the Samsung SM-G930W8 was spotted with three different chipsets. SM-930 is Samsung's codename for all S7 versions.
The two new possible processors are the MediaTek Helio X20 or the Helio X25. Both chips integrate deca-core CPUs. The X25 runs at higher clock speeds, although they are basically the same chipset. The W in the codename could refer to Canada, which it has in previous editions. If these leaks are true that could mean two more potential versions of the S7; four versions total.
Samsung Galaxy S7 audio
The built-in speaker of the S7 is loud and clear. It is optimized primarily for audio conferencing, so it isn’t so well-suited to the low frequencies that make for better music listening. A pair of in-ear headphones are included, and they come with an extra pair of rubber covers. These offer decent enough quality for listening to music. Using the software equalizer, the sound can be adjusted to your liking.
https://fs02.androidpit.info/userfi...ndroidPIT-Samsung-Galaxy-S7-vs-S6-87-w782.jpg
The Galaxy S7 also offers a clever voice-recording app that makes use of the top and bottom speakers to produce stereo recordings. This makes differentiating between multiple voices much easier.
https://fs01.androidpit.info/userfiles/6473453/image/neues_format/galaxy_s7_voice_recorder-w782.jpg
Samsung Galaxy S7 camera
The Galaxy S7’s camera is one of the best of any smartphone I’ve tested. The camera’s snappy focus and shutter time, in conjunction with the quick launch feature, make it fun, functional and an undeniable selling point. The results speak for themselves: very few photos do not come out well on the first attempt.
https://fs02.androidpit.info/userfi...xy-S7/AndroidPIT-Samsung-galaxy-s7-3-w782.jpg
Samsung has reduced the number of MPs on the main camera sensor from 16 to 12. Nevertheless, the quality of the photos produced sees a marked improvement. This is mainly because of the dual pixel technology the camera now employs, something that can be found on more expensive Canon SLR cameras. The advantage of dual pixel technology is, essentially, that the autofocus operates extremely fast.

With the shutter, Samsung goes one step further than the Galaxy S6. The aperture size has increased from f / 1.9 to f / 1.7. This larger opening allows more light to be let in, so pictures, particularly in low-light conditions, come out better. Of course, the Galaxy S7 also has an optical image stabilizer, which compensates for unsteady hands.
https://fs01.androidpit.info/userfi...y-S7/AndroidPIT-Samsung-Galaxy-S7-10-w782.jpg
As always, the photo app offers several features which provide a versatile range of exciting and fun things to play with. These include slow-motion and time-lapse imaging, access to numerous presets, as well as fixed focus and exposure values.
https://fs02.androidpit.info/userfiles/6473453/image/neues_format/galaxy-s7-camera-app-w782.jpg
The Galaxy S7 also packs a 5 MP front-facing camera with an f / 1.7 aperture. It, too, delivered amazing results in our test; the dynamic range held up well, even under poor lighting conditions.
Samsung Galaxy S7 battery
With just one charge, the Galaxy S7 will survive through the day, even with heavy use. In addition, the supplied charger can fully juice the battery in 90 minutes and the energy-saving modes are smart, functioning better than similar solutions found on other devices.
The Galaxy S6’s battery was a weak point, and rightly came under fire from many users. Samsung has taken this criticism on board and installed a 3,000-mAh battery in the Galaxy S7, up from the 2,600 mAh found on the Galaxy S6.
https://fs02.androidpit.info/userfi...xy-S7/AndroidPIT-Samsung-galaxy-s7-8-w782.jpg
Nacho Nieto, Head of Technology and Platforms at Samsung, explained to us that the battery in the S7 is malleable and, because of this, a 3,000-mAh variant was the only option. The moldable battery can also be customized so that it fills available space within the phone, which was not possible with the battery used in the S6.
Like the Galaxy S6, the S7 also supports wireless charging.
https://fs01.androidpit.info/userfiles/6473453/image/neues_format/galaxy_s7_save_power-w782.jpg
Unfortunately, another area of contention on the Galaxy S6, the fact that the battery is non-removable, has not been addressed. The only flagship to feature a removable battery so far this year is the LG G5.
Samsung has also equipped the S7 with some software features intended to save battery life. These features keep an eye on when the device is being used and put apps into a deep sleep mode when they have been ignored for three days.
This provides an extended standby time without limiting functionality. When other manufacturers attempted to include similar features, it meant that sometimes messages or emails arrived late, making the feature more a burden than a boon.
