After the Galaxy Note 7 failure that caused total recall of these smartphones, Samsung managed to get back on its feet quickly and in the end of March all this was forgotten because the Galaxy S8 came to the stage. Its sales started in April and to this day people are quite happy with it. Of course, there are a couple of reasons for all this hype.
It’s obvious that the South Koreans have done a great job in terms of exterior design which looks more attractive than ever with these extremely thin bezels. On the other hand, it is probably the case that some Galaxy Note fans have turned their attention namely to this series. Samsung Galaxy S8, however, is a premium-priced model and as such, it is expected to be perfect in every aspect. Whether it is really so or not, we will find out in this review.

Official video introduction
Design and construction
Galaxy S8 boasts a construction with glass back and metal frame, as it used to be the case with the previous two generations from this lineup. However, there is a crucial change manifested in the maximum possible decrease of screen bezels. This leads not only to an attractive impression but it has also allowed the company to increase the screen size significantly without affecting the overall dimensions. Additionally, this phone’s thickness and weight have been preserved nearly the same – 8 mm and 155 grams. It’s also good to note that we are now dealing wit a 5.8-inch display vs 5.1 in Galaxy S7.
This year there is no edge version but it comes with a display whose edges are curved along the sides and this makes the side bezels barely visible. Under the display, the familiar Home button is no longer to be found. There is no place for it anymore and the three traditional Android navigational buttons are on screen. Despite this, the Home button registers pressure and this operation is accompanied by a light vibration. The idea behind all this is to ensure hidden navigational buttons while you are playing a game, and if you press the Home button area and this will immediately lead you to the home screen. Pressing it can be used for quick unlocking of your smartphone.
Moving on, the area above the screen is significantly smaller but it still holds the front camera, earpiece, LED notifications indicator, proximity, and ambient light sensors, as well as the iris scanner. Unlocking via the latter is quite fascinating because it looks like a technology from the future, but actually more convenient is the fingerprint scanner which does not mind if you are wearing glasses or lenses, and you won’t have to hold the phone at a particular distance from your eyes.
Yes, the fingerprint scanner has been moved to the rear panel, right next to the main camera and you will get used to it in no time because it’s just as convenient as before. It is also in this area that we find the heart rate sensor and LED flash. Below them, you will only find a Samsung inscription and several product labels. Consider that the glass back retains fingerprints easily.
Furthermore, the side metal frame is even thinner now but there is some room for the volume controls (on the left) and the Power button (on the right). On the left, you will find a hardware button which is identical to the Power button and because of that, you will probably mistake them at first. We are talking about the new virtual assistant Bixby which will be discussed further down. Additionally, the headphone jack, USB-Type C port, main mic, and loudspeaker are placed at the bottom. And the top holds the secondary mic and hidden nanoSIM and microSD cards slot.
The entire construction looks solid and robust enough, and both sides boast Gorilla Glass 5 protection, and the IP68 certificate ensures water and dust resistance, allowing for up to 1.5 m dives for up to 30 minutes. In the YouTube videos below you can watch several durability tests that appeared shortly after the appearance of the smartphone.
In comparison to the 5.1-inch Galaxy S7, the Galaxy S8 features a 5.8-inch display and the best thing is that it has not resulted in a significant increase in the overall dimensions. Single-handed operation is just as comfortable and you have a bigger operational surface. Additionally, the Super AMOLED panel is still there but with increased resolution of 2960 x 1440 p. This ensures great image detail of nearly 570 ppi. The screen turns into a Retina when looked at from a distance of 15 cm or more (it is at such distance that the human eye does not make difference between separate pixels and it’s great for looking at a smartphone screen). In the settings menu, however, you have the option of setting a lower resolution and the default one is 2220 х 1080 p. The difference between the two is barely noticeable by the naked eye. We can’t but notice the feature-rich display menu, and we shall take a look at the most interesting among them below.
The graph below displays the max brightness in “Adaptive display” mode, launched “Auto Brightness” and in a very well lit environment simulating direct sunlight.
Moving on, the next image displays the Samsung Galaxy S8 colors and gamut coverage of several color spaces. We display the range of colors that the human eye can see on the “CIE 1976 Uniform Chromaticity Diagram”, through which you can get a general idea of the color gamut coverage and accuracy of the device. Inside the dark gray triangle are the standard colors used in digital TV and the Internet – rec. 709/sRGB. Colors within the dark gray triangle are used basically everywhere by millions of users, and their correct representation is often of key importance to the quality of the display.
Here, apart from the employed in professional cameras Adobe RGB color gamut, we can see the operational gamuts of famous film studios (DCI-P3) and the one of UHD digital TV (Rec.2020). The latter, Rec.2020, is difficult to manage by contemporary displays.
The black line denotes a color gamut described and examined by Michael Pointer – Pointer′s Gamut. It represents the colors that naturally occur around us every day.
Super AMOLED displays have wide color gamut. While many displays can’t cover sRGB, Samsung Galaxy S8 offers display modes allowing you to choose from several color gamuts with accurate coverage. The latter takes matters to a whole new level.
The yellow dashed line displays the gamut coverage of Samsung Galaxy S8.
The figure below presents our measurements in “Basic screen mode”. The color circles are the reference colors in sRGB, and the white circles represent our results. We have displayed the basic and additional colors with 25, 50, 75 and 100 % saturation in the sRGB gamut.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc.
The next figure presents our measurements in ” AMOLED photo screen mode”. Here the color circles stand for the reference AdobeRGB colors and the white circles – for the results. We have displayed the basic and additional colors with 25, 50, 75 and 100 % saturation in the AdobeRGB gamut.
Pulse-width modulation (Screen flickering)
Pulse Width Modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.
The graph below illustrates the presence or absence of pulsations. It comprises several measurements registered at several major positions of the brightness slider – minimum, maximum, operational (140 cd/m2) and potentially interesting transitional moments. And so, the vertical axis displays luminance while the horizontal one – time.
Samsung Galaxy S8’s display emits significant pulsations up to a certain brightness level (200 cd/m2), and lowering the brightness reduces the amplitude which decreases the negative impact.
Blue light emissions
After sunset, when our biological clock prepares our organism for sleep it is namely the blue component with 440 nm wavelength that unlocks hormonal imbalance, leading to a number of negative effects. You can read more about the Blue light impact in our dedicated article.
In the display menu, you can also find a blue light filter which will reduce eye strain, especially at night. You have the option of controlling the filter’s opacity and determine a schedule. If you turn your GPS on, the device will know when the sun rises or sets and activate the filter appropriately.
The next image displays the spectral power distribution of the emitted light.
We have encountered this mode in other Samsung models but this time it has been moved to the display menu. By activating “Easy mode” you’ll increase the size of the text and icons. This way you’ll have less stuff on your home screen. Moreover, you can select which apps you want to see on your home screen and get quick access to your favorite contacts since they’re all located your home screen.
This submenu features several different options such as selecting whether you want to have an app drawer or you would like to have all available icons on the home screen. You can also set the number of rows and columns for the icons and whether you want to have a dedicated Apps button or just use a swipe to open the app drawer.
It is from here that you can determine the color of the navigation bar and change the button placement or allow a hard press on the Home button to unlock your device. What’s more, you can even control the home button’s sensitivity.
It is here that we find two options that can be disabled. The first one is about the information you want to see on the display’s edge when swiping to the left. You can put frequently used apps, favorite contacts, weather information, sports results and much more. Another feature of the so-called Edge screen is its ability to function as an indicator for various notifications. Of course, you can choose which notifications to be included.
The display menu features a couple of other options such as protection against unwilling presses while the phone is in your pocket, change of icons layout, brightness and font adjustments as well as others. You can even choose the resolution of your screen and what apps can be spread along the entire screen.
Samsung Galaxy S8 boast a display that takes us to a whole new level. It covers several color gamuts with high accuracy, it has near to infinity contrast and superb maximum brightness, convenient viewing angles and high image detail.
|OS||Android 7.0 Nougat|
|CPU||Exynos 8895 (4-core, 2.30GHz & 4-core, 1.70GHz)|

Galaxy S8’s battery comes with 3000 mAh just as it was the case with the Galaxy S7. This time, however, we are presented with a mobile chip, consuming less energy, and we can expect good results. Do bear in mind that all tests were conducted in default resolution (2220 x 1080 p), not the maximum possible (2960 x 1440 p). We used the well-known five tests – a phone call, Wi-Fi, and 3G Web browsing, video playback and 3D gaming. The preliminary settings that apply to all devices we test are brightness of 120 cd/m2, turned on Wi-Fi module and turned off Bluetooth, GPS, and 3G (with the exception of the 3G browsing test).
In this test the screen doesn’t affect the battery life, since the proximity sensor turns it off during phone calls.

Battery settings and modes
In the battery menu, you will find two modes that limit its consumption. The first one makes some minor restrictions that could slightly increase the life between charges but the second one called Maximum power saving mode is more intriguing. It limits the maximum screen brightness to 80%, the mobile chip performance as well as the mobile data. Only basic applications and settings are available. Once again, you get information about the approximate durability of the charge under the given mode. The menu also includes information about the consumption of the various applications and the different time periods.
Software-wise, the Galaxy S8 features the best Google can provide. The phone uses Android 7.0 Nougat OS and you can be sure that it will be one of the first models featuring the next version of this mobile platform when it’s here. Of course, we are also presented with the latest issue of Samsung’s UI. One of the novelties here that made an impression on us was the way in which you can access the internal menu. This is possible via a swipe up or down in any part of the screen. In the same way, you can directly go back to the home screen. Additionally, the menu’s and icon’s layout, and there are some additional applications accompanying the traditional ones. An example is a Microsoft Apps folder which contains Word, Excel PowerPoint, OneDrive and Skype. We are also presented with a Samsung folder, containing apps such as Health, Samsung Gear, file manager and others. You will also find Samsung Note for notetaking and Secure Folder for hiding particular content.
Similar to previous Galaxy models, we are again presented with a “Themes” section. Each theme changes completely the UI layout starting with wallpapers, menus and icons. You also have a shortcut to the Samsung store where you can find a great number of themes.
In the settings menu, you will find a submenu called “Device maintenance” which offers useful information about battery, storage, memory and device security.
The front camera can detect your face and keep the screen on until your eyes look somewhere else.
By quickly double pressing the Home button you can directly launch the camera app.
Smart capture allows you to take a screenshot by sliding your hand along the screen’s surface, and you have the option of cropping certain parts of the picture.
With Direct Call you can directly call a given contact without even touching your smartphone. For this purpose, you need to bring the phone close to your ear and it will automatically dial the contact that has been on your screen last.
When you have missed calls and messages, the phone has the option of vibrating every time you grab it in your hand, in case it has not been on you before that.
By covering the proximity and ambient light sensors you can mute an alert or an incoming call.
One-handed is a mode that can be activated by a diagonal swipe upwards or by pressing the Home button three times. This will reduce the screen and allow you to reach any point with the thumb of the hand you are holding the device with.
Apart from unlocking the smartphone, the fingerprint scanner can be used to open the drop-down menu by sliding your finger on the scanner itself.
Multi window allows you to open two apps simultaneously on the screen, and you can choose how much space they can occupy.
By swiping right on top of a contact you can directly call them.
The features menu also has a video enhancer which makes colors brighter and more vivid.
Game Launcher will arrange all of your games in one place. Apart from this, it will offer additional options such as disabling notifications when playing a game and a battery saving mode. The latter includes two options – both decrease the resolution and frames per second in a game. You will find various offers for games which can be of potential interest.
Bixby is another novelty that Samsung highlighted. It is a new virtual assistant that even boasts a dedicated hardware button. It can be used with voice commands (when the button is pressed), text or touch. You can even capture a given object with your camera and Bixby can search info about it after that. Bixby checks prices and shops where you could buy a given product, gives info about various sights and restaurants that you could visit, recognizes QR codes and more.
Apart from using the hardware button, you can launch Bixby by swiping to the right while you are on your home screen. In it, you will find personalized info about everything of interest to you – up to date news, upcoming tasks, weather forecast, daily activity and everything else. Apart from this, Bixby self-teaches itself according to your interests and usage.
Lock screen and safety
In the “Lock screen and safety” submenu, you will find the fingerprint options which allow you to not only unlock your device but also confirm your identity in certain apps. We can say that the scanner is fast and accurate.
Samsung’s Always on option was first encountered in Galaxy S7 but it is also present here. Once activated, it lets you see the time, date, missed notifications and even a small calendar on your screen at all times. It doesn’t drain too much battery since it only activates the necessary pixels on the Super AMOLED panel instead of you having to turn on the whole display. At first, it may seem strange seeing information on your screen at all times, but you’ll get used to it and you’ll probably find it to be a very useful and neat feature since you won’t have to turn on your screen so many times a day. Anyway, you can turn it off at any time if you don’t like it, but keep in mind that it might actually be saving some battery since you won’t be turning on the screen that often, as Samsung likes to remind us.
One of the novelties that caused a lot of hype before the announcement, was the iris scanner. It is relatively quick to detect your eyes but there seem to be far too many requirements which make the fingerprint scanner more convenient. If you want to have your eyes scanned, you should keep your phone at a particular distance from your face. Also, unlocking won’t be possible if you are wearing glasses or lens. It’s a fact, though, that this is a really fancy way to unlock your phone and show off.
When it comes to the SoC, Samsung Galaxy S8 is offered in two versions. Within the United States the model comes with a Snapdragon 835, while in Europe you get the version with an Exynos 8895, which we used in our tests. Exynos 8895 has eight cores, the first four of which are Exynos M1 and tick at up to 2.3 GHz, while the second group uses Cortex-A53 architecture and operates at up to 1.7GHz. Samsung has improved the architecture design of their Exynos M1 cores which has lead to an increase in performance and a decrease in energy consumption.
Exynos 8895 is the first chip manufactured through a 10nm FinFET technological process, making Galaxy S8’s operation even faster, reducing energy consumption by 40% and increasing performance with up to 27% in comparison to its 14nm counterpart. Additionally, the chip supports LTE Cat 16 connectivity which will ensure download speeds of up to 1024Mbps and upload speeds of up to 150Mbps. The SoC also supports up to 28MP front and rear cameras, 4K screens and 4K video recording at 120 fps. Thanks to the two mini processors for image processing, Exynos 8892 can work with dual cameras as well.
The mobile chip comes with the new Mali-G71 GPU which has 20 cores, ensuring with up to 60% higher performance when compared to its predecessor. Samsung also claims that the chip will maintain low temperatures even after a continuous load, and that energy consumption will be significantly lowered. More information about Exynos 8895 can be found on the official page: http://www.samsung.com/semiconductor/minisite/Exynos/w/solution/mod_ap/8895/
Galaxy S8 comes with 4GB of RAM and 64GB of internal storage. However, from the very first time you turn it on, 11.7GB will be occupied by the OS and additional files. Nonetheless, you have a microSD card slot that supports up to 256GB, if you need to expand.
Geekbench 3.0 is Primate Labs cross-platform processor benchmark which simulates real-world scenarios and gives a combined score, based on the results of integer, floating point and memory performance.

Alas, we could not find a game in the Google Play store which can pose any difficulties for the Galaxy S8. You can see videos of our gaming challenge sessions below.
Temperatures and comfort
Along with the performance of this SoC, we would like to also check the extent to which it leads to overheating. According to Samsung, there is nothing to worry about but we conducted our temperature tests (3D gaming and 4K video recording).
The first test consists of several hours of 3D gaming simulated with the help of the Epic Citadel app. Immediately after it, we measure the max temperatures in three different areas of the smartphone’s back. The hottest point in this test was the mid section where we got 34.0 degrees Celsius. This is by no means a worrying value.
10-minute 4К video
It got a bit hotter after the second test which is more burdening. After 10 minutes of continuous 4K video recording, the max temp rose to 41.6 degrees, again in the mid section. As for the other two areas, they were similarly warm and the device was warm to touch but not hot. The metal frame got a bit hotter but this will not lead to any significant inconvenience.
At least on paper, there are no differences between the camera in Galaxy S8 and that in its predecessor. We are again presented with a 12MP sensor with autofocus, LED flash, f/1.7 aperture, optical image stabilization and 1.4 µm pixel size, which allows for more light to come in and hence clearer images in low light. In terms of software, however, Samsung has made some changes and the result can be clearly seen. If among the pictures taken with Galaxy S7 there used to be some with warmer colors (yellowish tints), with Galaxy S8 there is no trace of such phenomena. In this case, we are talking about the automatic mode because the two models have a Pro mode which offers manual setting such as white balance adjustments that can improve image quality to a certain extent.
A camera’s resolution is determined not only by the number of pixels on the sensor. It also depends on the resolution of a lens. A high megapixel count is meaningless if the lens lacks the needed sharpness. At the moment when the latter represents two thin neighboring lines as one, we can’t make them two again, no matter how many times we increase the number of pixels.
The total resolution of a lens and sensor is always lower than the lower one of the two, and that’s why a perfect balance is needed. We should not forget the third factor – the combination of hardware and software for image processing, whose perfection plays a key role for the quick camera operation and good image quality. The overall resolution is measured in lph (lines per high) with the help of the below table (as per ISO 12233).
Samsung Galaxy S8’s camera achieved max resolution of 2050 lph on the horizontal axis and 2350 on the vertical one. A good result for a 12MP sensor.
Menu and features
Furthermore, the camera menu that can be opened by a swipe to the right includes several modes. The Pro mode will give you access to various settings such as shutter speed, exposure, ISO, white balance and others. Additionally, the selective focus allows you to choose what to be in focus – foreground, background or both. Also available is a “Food” mode which makes your images contrastier. By swiping to the left, you get access to a wide variety of filters that allow you to make your image even more attractive. Also present are different stickers and stamps.
You can customize the moment and the extent to which the recorded video will be in slow motion.
Full HD video
It is true that you can record 4K videos with great details but if you want to save some storage, Full HD videos are quite decent as well.
The front camera is now 8MP and it also offers f/1.7 aperture. What’s more, there is intelligent autofocus which tracks faces so that everyone will be in focus. It is here that you will also find several modes that include wide selfie allowing you to capture more people in one shot, and selective focus which lets you choose what part of an image you want to be focused. Again, there are various effects, stickers, etc.
The long expected Samsung Galaxy S8 is now a subject to great interest. It was back in 2016 that the South Koreans upped the ante really high with the announcement of Galaxy S7 and now they had the difficult task to jump even higher. The Galaxy S8 comes with a similar design that cannot go unnoticed. What makes the model truly remarkable is the curves along the two edges of the display and its thin bezels. Additionally, this year’s flagship remains water-resistant, keeps the heartbeat sensor as well as the fingerprint scanner, located on the device’s back. A novelty here is the iris scanner which will allow you to unlock your smartphone with your eyes which is not as practical as it is cool.
S8’s display comes with a QHD resolution and a Super AMOLED panel which covers several color gamuts with high accuracy. It also boasts great contrast and maximum brightness. Additionally, there are improvements in the mobile chip which is Exynos 8895 now and it offers, as you might expect, high performance, while at the same time lower energy consumption. It is for this reason that the model did pretty well in most of our battery durability tests. As far as other merits are concerned, we can add that gaming on this device is rather smooth and the external temperatures after load are low.
In addition to the up to date Android 7.0 Nougat OS, you get an incredibly rich in features user interface. The main camera is 12MP again and the awesome shots we took with it are entirely in accordance with what you might expect from a flagship model such as Galaxy S8. Furthermore, its menu contains some additional options that allow you to make your photos even more appealing.
