Review of Samsung Galaxy S7: no compromise

In its previous flagship, Galaxy S6, Samsung company has implemented several bold decisions, which were not warmly received by users. Fortunately, the producer heard the criticism, and took into account the main claim of buyers returned to the Galaxy S7 memory card slot. In addition, the gadget received a traditional increase in productivity, a larger amount of RAM and a new camera, which although it has a lower resolution, but removes much better in the dark. This is only a small part of the "chips" news, if you want to meet everyone - welcome under the cut. Samsung user manuals here.

Box content and Packaging

Included with the Samsung Galaxy S7 are power supply, micro-USB cable, headphones and a Samsung Galaxy manuals. Moreover, now the flagship of the company are equipped with USB OTG adapter to connect to external storage devices and peripherals - a useful little thing.


Apparently, the Samsung was considered the best design of its previous leader, but because it is virtually unchanged migrated to the new model. As before, and front and back of the smartphone are made of glass, and the perimeter of the body protects the metal frame. The most notable innovation in housing - beveled verge of the rear panel, making the device a little more comfortable in the hand.

Camera lens protrudes noticeably smaller, and the right of it are still in LED flash and pulse sensors and SpO2 (oxygen saturation of the blood sensor).

On the front panel of the display are the earpiece, front camera and proximity sensors and light exposure, and under the display - touch buttons "Back" and "Application manager", as well as mechanical button "Home", combined with a fingerprint reader.

On the left face of the unit taken out separate volume buttons on the right - the power button.

The upper end of the device is busy microphone and a slot for SIM-card nano-SIM format, and a microSD memory card. At the lower end are located micro-USB port, 3.5mm audio jack, the main speaker, and another microphone.

Both the smartphone protected by Corning glasses of last generation - Gorilla Glass 4. However, if the front panel is coated with oleophobic coating quality due to which her little remains of prints on the back of this coating does not. As a result, for the appearance of the gadget you need to follow, because he is quickly spoiled in real life.


In our time, the device display with a diagonal of 5.1 inches has not dare to call great. We have long been accustomed to such devices and can easily use them with one hand. In addition, the streamlined body Galaxy S7 is really comfortable in the hand and cuts into the hand when trying to reach with your thumb to the upper left corner. But, if you screen smartphone still seems big, you can enable one of the two control modes with one hand. The first moves in one of the lower corners of the keyboard and button interface of a number of standard programs, such as the dialer and calculator. The second mode shifts in the corner of the screen and the whole interface can be enabled by pressing the triple-button "Home".


Galaxy S7 is equipped with a Super AMOLED display with a huge resolution - 2560h1440 pixels (QHD), which gives a pixel density of about 577 ppi. Without a microscope to see on this screen irregularities in the mapping even small items is simply impossible - the picture looks quite realistic. The transmission quality, contrast ratio and maximum brightness is also worthy of all praise.

But even the best AMOLED-display still suffer from color distortion when tilting the device - gamma shifts slightly in colder range. Daily use smartphone that does not interfere with and impressions of the gadget does not spoil, but this feature is worth bearing in mind.

As with other Samsung devices with AMOLED-display, in the Galaxy S7 you can adjust the color saturation by standard means. Maximum saturation shows all that are capable of such a matrix, the minimum can be useful to those who are accustomed to the IPS-displays.

Adaptive brightness screens of smartphones Samsung and used to work fine, but now it will focus not only on the ambient light sensor readings, but also on your preference. When tuning the brightness manually from the panel notifications Smartphone will remember your selection and, in the future, under the same conditions of ambient light, offer you the same option.


Samsung Galaxy S7 runs Android version 6.0 Marshmallow, on top of which, as usual, set the manufacturer's proprietary shell - TouchWiz. launcher design in the latest version even more closer to Material Design, use it was really nice. The most important change in the shell, which have been waiting for all users of Samsung smartphones - the disappearance of "eared" avatars in the contact list, instead of them now simply displays the first letter of the name.

In part, this is a joke, but it was the little things and create an overall impression of a smartphone. Such changes have affected not only contacts but also the notification bar, which has changed the scheme - now switches it turned blue icons on a white background, and prevents many item "Quick Connection" can be removed in the settings. Despite the absence of major changes, TouchWiz became cleaner and more modern - now the shell will surely enjoy even adherents AOSP.

The word "cleaner" is meant not only the appearance of the launcher, but also pre-installed programs. Of course, they are still a lot, but no more of dominance by countless third-party applications, which has been before. In addition to the Samsung and Google in the smartphone preinstalled office suite from Microsoft, offering a gift to 100 GB in the cloud OneDrive, Facebook, WhatsApp, Instagram, Ubank and Yandex. If you do not need these programs, the Microsoft's applications can be disabled by removing from the list of programs, and the rest - simply remove.

Despite the apparent simplicity, the TouchWiz has kept a lot of different functions that have always been its main feature. Since the main "chip" shell like eye tracking or gesture control were TouchWiz before, the review will be discussed about the new shell functions. One of them appeared not so long ago with another OTA-upgrade - scaling. scaling work, in fact, similar to the program changes dpi, which is possible by external methods only if the superuser. When the compressed size, and the device is reset all the items on the screen will be reduced and the display will be placed more information: the example you can see in the screenshots below. However, even if the compressed scale of some elements still appear to be too large - let's hope that in the future, Samsung will add more options to change the dpi.

Also in the settings of the new TouchWiz appeared Galaxy Labs division, which Samsung plans to add test features before deciding on their final implementation in the firmware. Now these two functions - transfer labels of all applications from a single panel on the desktop and quick call contacts by pronouncing their names while holding down the "Home".

Another new feature - always on display. Even when the phone is locked, a variety of information, such as a clock or calendar can be displayed on the screen. Due technology AMOLED, this function has virtually no effect on the battery life time.

Not to mention the multi-mode, which first appeared in smart phones is the Samsung gadgets. To work in this mode, you can directly in two ways: by dividing the screen into two or more floating windows open, which may overlap. In both modes, you can resize the window and drag information between them (if the applications themselves support it).

The device in the work

 Samsung has released several versions of the smartphone, including a processor from Qualcomm's, but on the test model was Samsung G930F, which is intended for sale in Europe, including in Russia. This version is equipped with 64-bit chipset Samsung Exynos 8890 Octa on ARM big.LITTLE architecture. The chipset includes four core Samsung Mongoose with a clock speed of 2.4 GHz, quad-core ARM Cortex-A53 with a frequency of 1.3 GHz and a graphics accelerator ARM Mali-T880 MP12. Cores Mongoose became the first South Korean company's own development and are improved core ARM Cortex. Do not be amiss to note that the Exynos 8890 - one of the two mobile chipsets in the world, performed on a 14-nm process technology. In addition, the device has received a 4 GB memory LPDDR4 standard, as well as 32 or 64 GB of internal memory UHS 2.0 standard - it is the fastest memory in mobile devices today. In testing the model came with 32 GB of memory, because it is available only to the user about 20 GB, but it will not interfere: in the flagship Samsung returned a microSD card slot that supports cards up to 200 GB. Also, if necessary, you can use with supplied USB OTG adapter and connect the smartphone to the external drive.

About performance S7 superfluous words is not necessary - it is one of the fastest and most powerful smartphones in the world today, it is no problem to cope with all the games and other tasks.

Speaking of games: in the Galaxy S7 manufacturer has decided to focus on them, adding to the application firmware Game Launcher. This directory installed on the smartphone game with a number of special functions. This includes disabling notifications, reduce power consumption in the games, which is achieved by lowering the resolution and the number of fps to, as well as the Game Tools - floating icon, by clicking on which opens a context menu. His most useful features - off touch navigation buttons and a video recording from the screen.

AnTuTu test results 3DMark and you can see in the screenshots.

One of the flagships of the brand of chips Samsung - a fingerprint scanner built into the button "Home". Works flawlessly Scanner: to turn the screen on and unlock the device by pushing the button for more than a second. Who would not say that, but the location of the scanner on the front panel - the most successful of all: before unlocking is not required to press the power button, and there is no difficulty when the gadget is turned on when it is on the table. In addition to the release of the smartphone in the Galaxy S7 scanner can be used to log in to Samsung account and to login to the site in a standard browser.

More two sensors that have become the hallmark of flagship Samsung - heart rate and blood oxygen saturation sensor. Measurement of heart rate, level of SpO2, and stress levels through S Health app, which can also carry the weight diary, exercise and other events related to health. Several measurements can be automated - S Health supports the connection of third-party accessories, including the ANT + technology.

Perhaps the only real oddity of this smartphone - using micro-USB port instead of the USB Type C. It is not very clear solution leader in the era of mass transition to a comfortable standard, and, moreover, USB Type C is easier to do on the USB 3.0 standard . Port micro-USB 3.0 has a large size and not caught in smartphones, so Galaxy S7 owners have to be satisfied with the speed of USB 2.0.


As the main camera in the Galaxy S7 uses a 12-megapixel module Sony IMX260 - this sensor has been created specifically for Samsung, and is not sold to other manufacturers. Compared with the previous version of the flagship camera resolution in the Galaxy S7 it fell, but it happened by increasing the physical size of each pixel, thus became the perfect smartphone to shoot in the dark. Another advantage of the new sensor - an improved phase detection autofocus, which involved all of the pixels of the matrix, compared to about 5% in the previous models. The result of this - instantaneous focusing even in difficult circumstances, and taking into account the overall performance of a smartphone, gadget when you open the camera is ready to shoot in less than a second.

All this led to the fact that the Galaxy S7 now - one of the best cameras in mobile devices, which copes with almost all subjects, including shooting in low light. Small artifacts can appear except on night photography. The picture quality can be estimated by the examples below.

Separately say about the "Panorama" mode in which the glued full-size photos and the final resolution of these images is 38 megapixels.

Video recording is possible on the main camera in resolutions up to Ultra HD, and the maximum frame rate for standard recording mode - 60 fps - achieved in the resolution of Full HD. In slow mode, shooting speed is increased up to 240 fps, but the resolution is reduced to HD. Due to optical stabilization, video out clear and smooth, but if you include the HDR, the obstacle to the creation of video will not be even the bright sun.

The app "Camera" in the Galaxy S7 has changed little: it still has a panel with buttons fast setting, lots of shooting modes and the ability to download additional modes of the Samsung store, also you can download Samsung Phones PDF user guide.

Wireless interfaces

As befits a top smartphone, Samsung Galaxy S7 has a complete set of wireless interfaces: Wi-Fi 802.11a / b / g / n / ac with support for frequency bands 2.4 and 5 GHz, Bluetooth 4.2 low-power, NFC and ANT +. It is worth mentioning the new tethering your smartphone: Now when you activate on the gadget access point Wi-Fi, the smartphone will be sharing an Internet connection, not only over cellular networks, but also through other access points. In fact, it means working in repeater mode, which is useful for travel, for quick connection to Wi-Fi all their devices, as well as at home if your router does not suddenly "finishes" to the far room.

With the cellular phone as there is no problem on the LTE data transfer speed is limited only by the capabilities of operators, and a huge number of supported channels allow the use of high-speed connection to the Internet in almost all countries.

Battery life

The gadget is equipped with a non-removable battery on the 3000 mAh battery, and even in this section can not be said about the right number of "chips". First, it is quick charge Quick Charge 2.0, which allows you to charge the battery to 60% within 30 minutes. Second, the smartphone supports wireless charging from two standards, of Qi and PMA. Moreover, the wireless charging can also be a quick (full battery charge in 90 minutes), if supported by your stand. Finally, it is still here extreme power saving mode in which the smartphone on a pair of the remaining percentage can stretch a few more hours.

In addition, the manufacturer has carried out other work to optimize the energy consumption of the smartphone, resulting in a full day of battery life with the time of the screen for more than four hours. If you use the gadgets are not as active, then you can work out the Galaxy S7 and a half and two days - in standby mode, the device consumes very little energy.

The results of testing the gadget autonomy in continuous loads are also impressive: on average in brightness games S7 lasted exactly 10 hours, and when playing Full HD video in flight mode at full brightness - more than 14 hours.


Samsung continues to hold a leading position among the manufacturers of Android-smartphone. Galaxy S7, as well as other flagships of the company uses the latest technology, has huge headroom, and to explore all of its features and customization capabilities can take more than one day. Special attention is given camera, which produced perfect shots day and just good photos at night - on the quality of her approach can not so many other mobile gadgets. But noticeably grown device autonomy and the ability to make rapid charging situation when the smartphone is switched off by the end of the day, virtually impossible. Samsung Galaxy S7 became smartphone for those who want to get the most and is not ready to make any compromises, including the price device.
