Galaxy S8 Plus

It was in March 2017 that the Korean company Samsung unveiled the Galaxy S8 and S8 Plus.

The original design of the Samsung Galaxy S8 Plus is one of the phone models with the same capabilities and features as the original phone, which is available to users with a very real and ideal fingerprint sensor. This mobile phone has high quality with a design very similar to the original version.


The Galaxy S8 Plus is about the same size as the iPhone 7 Plus; But unlike this phone, which has a 5.5-inch display, the Koreans have managed to use a 6.2-inch display on the Galaxy S8 Plus. Although the Galaxy S8 Plus does not have the ergonomics of its smaller sibling; again, thanks to the extraordinarily narrow bezel of the display, it is not as difficult to work with as other phablets on the market.

When you first get the Galaxy S8 Plus, you are shocked by its amazing build quality and design. Despite the large screen, holding this phone is very enjoyable. Undoubtedly, Samsung is now at the forefront of the mobile world in terms of design with its eighth-generation galaxies.

Although the Galaxy S8 Plus is a fairly large phablet due to its 6.2-inch display; thanks to its smaller width than other phablets on the market, it has good ergonomics, and on the other hand, the elimination of the sides of the phone and the narrower top and bottom margins, has caused the Galaxy S8 Plus to replace the 5.7-inch S7 Edge display. See a very large 6.2-inch screen.

Of course, as long as you do not want to drag the notification bar down because the increase in height of the phone has made it impossible to touch the top of the phone with one hand and activate the notification bar. However, to solve this problem, Samsung has considered a one-handed operation, which is activated by touching the Home touch button three times.

The Galaxy S8 Plus is only 8.1 mm thick and weighs 173 grams, which makes sense for a phablet of this size. The width and height of the Galaxy S8 Plus are 73.4 and 159.5 mm, respectively. Of course, this phone is about 1.2 mm wider than the Galaxy S7 Edge, which is negligible due to the 0.7-inch increase in screen diameter.

The front panel of Samsung’s new Galaxy is completely black, regardless of body color; This issue, along with the removal of the physical button and its replacement with a touch button, have made it possible to see a beautiful and uniform design when the screen is off, and on the other hand, the various sensors of the phone located at the top of the screen do not cause clutter in the device design.

The strong metal frame of the phone is placed with exemplary precision in the heart of the front and back glass cover of the phone so that we can see more and more integration between the different parts of the product. The main camera of the device, along with the flash and fingerprint sensor, is well placed in the heart of the body so that its protrusion does not bother.


Usually, one of the main strengths of Samsung’s flagship phones is their display, and this year’s Korean galaxies are no exception. In recent years, Samsung has gained some expertise in the production of AMOLED panels. Unlike last year, when Samsung launched the Galaxy S7 in two versions with flat screens (Galaxy S7) and curved (Galaxy S7 Edge), this year there is no flat screen and the edges of the screens of both Galaxy S8 and S 8 Plus are curved.

Of course, the curvature of this curvature is slightly less than the Galaxy S7 Edge, and Samsung has eliminated the negative effect of unwanted touch on the edges so that if your hand hits the edges during use, there will be no problem in the performance of the phone.

The display of the Galaxy S8 Plus is Super AMOLED, with a resolution of 2960 x 1440 pixels or WQHD + and dimensions of 6.2 inches. This resolution brings a density of 529 pixels per inch; Therefore, images and texts are displayed with extremely high resolution. It is safe to say that Samsung’s new flagships are equipped with one of the best displays in the world of smartphones.

The Galaxy S8 Plus display, like the one used in the smaller version of the phone, displays stunningly sharp and dynamic images, and the color accuracy produced is very high. The Galaxy S8 display also supports HDR technology and is UHD certified with Mobile HDR Premium certification, which displays dynamic, near-realistic images; Of course, in order to be able to take advantage of the feature, the content you want must also be HDR.

The brightness of this display in the highest state reaches about 650 nits, which is a very significant number; Therefore, in bright and sunny environments, working with the phone will not be difficult. As expected from a flagship in 2017, the Galaxy S8 Plus display also offers a wide viewing angle, and at different angles, we do not see a decrease in color accuracy.

Samsung has set an unusual 18.5 to 9 aspect ratio for the Galaxy S8 series, which has made both phones look taller than their predecessors. Samsung calls the Galaxy S8 display Infinity Screen.


Perhaps one of the few weaknesses of the eighth generation of Samsung galaxies is their speaker. With companies such as Apple, HTC, and Sony now using stereo or dual speakers in their phones, Samsung is still true to its previous strategy and has used a single speaker in the Galaxy S8. The clarity and sound quality of these speakers are acceptable, But their volume can not be compared with dual-speaker phones.

Samsung has also remained faithful to the 3.5mm headphone jack and has used it in the Galaxy S8 Plus. Samsung also comes with the AKG brand of headphones. The headphones of the Galaxy S8 have a very high build quality and the sound output from them is very good from both the point of view of loudness and sound quality.

Security features

Samsung offers a variety of biometric security features for Galaxy S8 and S8 Plus users; These features include a fingerprint sensor, face recognition sensor, and iris sensor. As mentioned in the design section, in order to reduce the thickness of the lower edge of the screen, Samsung has removed the physical Home keys and capacitive navigation keys and replaced them with software examples; Therefore, the location of the fingerprint sensor has changed from the front panel to the back panel and to the right of the camera. The fingerprint sensor is set up easily and in several steps, and after the start-up process, just touching the sensor, unlocks the phone in a fraction of a second.

One of the few flaws in the design of Samsung’s eighth-generation galaxies is the unusual location of their fingerprint sensor; This sensor is located on the right side of the camera, and since the camera is also flush with the body; So sometimes you may touch the camera instead of the sensor, and this will leave a fingerprint on the camera cover. But due to the much larger dimensions of the S8 Plus than its smaller sibling, access to the fingerprint sensor is a bit more difficult.


As in previous generations, Samsung has used two different sensors in the Galaxy S8 and Galaxy S8 Plus. Some of these phones are equipped with Sony IMX333 sensor and others use ISOCELL 5K2L2 sensor, which is made by System LSI (one of the companies controlled by Samsung). However, these sensors are manufactured by two different companies; But the specs are the same: Both sensors are 12.2-megapixel and 1/2.55-inch, and they support Dual Pixel ultra-fast focusing, a phase-detection autofocus system called PDAF, and an f / 1.7 lens. The size of the pixels is the same in both versions and is equal to 1.22 micrometers.

Experiments performed by various experts show that there is not much difference between the image quality and the performance of these two sensors, and this is not a cause for concern.

Samsung has focused on the selfie camera in the Galaxy S8 series. The spheres feature an 8-megapixel, 3.6-inch sensor with an f / 1.7 lens and autofocus capability. Samsung has also included smart autofocus for the selfie camera so that everyone is in focus, even when using a monopod. In this system, faces are automatically detected and focused on.

Operating system and user interface

Given that the Galaxy S8 Plus was introduced in 2017; It is not surprising that Android 7 Nougat is installed by default. Of course, the Android 8 Orio update has been released for this phone and can be installed OTA, but in any case, the default operating system of the Android 7 device will be Nokia. The Samsung Experience UI on the Galaxy S8 Plus is more efficient than the company’s old TouchWiz UI and has a better look and design style. The Samsung Experience will also be lighter and smoother than the TouchWiz.

Due to the good hardware platform that the Galaxy S8 Plus benefits from, you will not face any lag or delay while using the device, and even its software weaknesses will be partially covered. Samsung has made really good changes to its new user interface over the years, making it easier and easier to use than the Galaxy S8 Plus.

The speed of operation of the device platform and user interface is very desirable and without a doubt, you will not face any problem in this regard. The Galaxy S8 Plus uses Bixby or Samsung’s own smart and dedicated assistant.

Processor, RAM, and internal memory

One of the most important things to consider in reviewing the Samsung Galaxy S8 Plus is the performance of the device. In terms of chips, the Galaxy S8 Plus comes in two different versions, using Qualcomm’s Snapdragon 835 and Samsung Exynos 8895 chips, respectively. 1.9 GHz Cortex-A53 cores and the second set consisting of four Mongoose M2 cores clocked at 2.3 GHz. In addition, the Mali-G71 MP20 graphics processor in this version of the phone is responsible for analyzing graphic data.

Samsung Galaxy S8 Plus in terms of RAM includes two different versions with capacities of 4 and 6 GB, respectively. Each of the two versions of the product has 64 and 128 GB of internal memory, respectively, and supports Micro SD (RAM) connection. According to Samsung, interested users can increase the device’s data storage space up to 512 GB by installing microSD RAM. But how powerful is the device? You might think because the Galaxy S8 Plus was the product of 2017, it should not have too much performance, but in practice, it is not!

In reviewing the Samsung Galaxy S8 Plus, it was found that this phone handles all kinds of HD and heavy Android games such as Asphalt 8, Dead Trigger, etc. well and without any problems, and there will be no lag or delay in its performance.

Efficiency and performance

The Galaxy S8 Plus comes with two different processor models, one with the Snapdragon 835 and the other with the Exynos 8895. But the models that enter the domestic market are equipped with Exynos processors; But the Exynos 8895 processor is based on the 10-nanometer FinFET manufacturing process, which consumes more energy and is smaller than the 14-nanometer processors, and generates less heat.

Samsung claims that the company’s 10-nanometer processors consume about 40 percent less power and 27 percent more efficiency than the 14-nanometer LPE FinFET models. The chip also uses an LTE-A modem capable of supporting speeds of one gigabit per second. But the Exynos 8895 processor comes with 4GB of RAM and 64GB of internal storage, which can be upgraded to 256GB via a microSD card slot.


Although the Galaxy S8 Plus is slightly larger than the Galaxy S7 Edge; Surprisingly, Samsung has used a smaller battery in its high-end phablet. The Galaxy S8 Plus uses a 3,500mAh battery that is 100mAh less than the Galaxy S7 Edge battery. In order to keep the phone’s battery consumption at a controlled and acceptable level, Samsung has set its display resolution to FHD + by default; Of course, you can also choose WQHD‌ + resolution; But in this case, an error message is displayed stating that the battery consumption has increased.

Galaxy S8 Plus vs. Galaxy S8

The Galaxy S8 and S8 Plus are arguably the most exciting Samsung galaxies the Koreans have ever launched. For the eighth generation of its galaxies, Samsung has designed a beautiful display with ultra-narrow bezels, accompanied by powerful hardware and a high-quality camera. But which of these phones is right for us? Each of the Galaxy S8 and S8 Plus handsets has advantages and disadvantages that can affect the user’s choice when shopping.

Perhaps the most important advantage of the Galaxy S8 is its good size and weight. Thanks to Samsung’s optimizations, the Galaxy S8 is smaller than the Galaxy S7 and weighs the same.

This makes the S8 very ergonomic despite having a 5.8-inch display, and it is easy to work with one hand, But the battery capacity of the Galaxy S8 has not changed from the past, and this may be considered a negative point for it.

The most important strengths of the Galaxy S8 Plus can be considered the larger display and its 3500 mAh battery, which has very good and satisfactory charging.
