The main update points of Samsung Galaxy S8/S8+include 18.5:9 rounded curved screen, cancellation of entity home key, new human face recognition, Snapdragon 835/Exynos8895 and Bixby AI assistant. Let's now look at the substantial impact of these changes:
parameter
The test machine models we got are G950F and G955F, which use Exynos 8895 processors, and the sensors are Samsung S5K2L2.
Appearance: screen proportion and glossy border
PS： Some testing machines have holes in the earpiece and the bottom, which is the logo of engineering machines, not mass production machines.
Samsung The Galaxy S8 still continues the design language from the Galaxy S6. The overall outline of the body is very similar to that of the Galaxy S7 (the outline of the mainframe is more like Note7), but after the screen is changed to 18.5:9, the scale becomes more slender. The back is also a familiar hyperbolic face scale design. The flash lamp and heart rate sensor are moved to the left, and the fingerprint identification module is put down on the right (cannot be pressed, but the notice bar can be pulled down/folded by sliding). The other parts are almost unchanged.
Although a little “ The designer is suspected of being lazy and squeezing toothpaste, but the ultra-high screen proportion and hyperboloid make the design of the screen extending to both sides of the body look really shocking.
The frame of the silver version is also silver, which will directly reflect the luster of the surrounding environment.
The highly compressed forehead and chin are very powerful. There are as many as 7 forehead openings, with iris, distance and light sensor, front camera and many other modules plugged respectively. The earpiece is also much shorter than the previous generation.
Layout: The layout of the fuselage has not changed significantly. The power supply on the right and volume buttons on the left have been changed to be integrated, and the Bixby button has been added. At the bottom are earphones, Type-C connectors, microphone and speaker openings, and at the top are card slots. The G950F/G955F is designed as a single card. Only one nano SIM card and one TF card can be inserted into the SIM card slot. The base material is still plastic with waterproof sealing gasket.
Workmanship: It can be seen from the top and bottom of the fuselage that the 2.5D radian of the curved glass side is smaller than that of the previous generation, but the glass is still higher than the metal frame. The gap between glass and metal frame is very small, And there is no plastic washer, The arc extension and connection are very natural, even better than Note7. The overall workmanship is impeccable, but the probability of dropping the broken screen is really high (the metal frame will directly extrude the glass after new deformation).
Bright border: In addition to the screen, the biggest change in the appearance of the real machine is that the metal frame also becomes bright, a bit like the bright black version of the iPhone. The gloss is more consistent with the front and back glass, and the whole machine is more like a pebble. Both front and back glasses have anti oil coating, but this bright metal coating is really easy to get fingerprints/dust/oil stains.
Appearance comparison between S7 edge and S8/S8+
The body width of the S8+with a 6.2 inch screen is only 0.8mm wider than that of the S7 edge with a 5.5 inch screen. There is not much pressure on a single handheld grip. However, the main problem is that the fuselage is a bit longer than the S7 edge. It is difficult to touch the notice bar when holding it in a normal posture
The S8 is a bit narrower than the S7 edge (the square at the bottom of the S8 chin is a unique coating opening for engineering machines, but not for mass production machines).
The layout of keys in S8 is the same as that of the previous generation, except that the keys are more slender and coated, the volume keys are linked together, and the Bixby button is added.
For the two generations of the same blue machine, the S8 even has a bright blue frame, and the 3D is significantly smaller than the previous generation. The curvature of the screen becomes smaller, and the border width is close. It is worth noting that the blue and silver versions of S8/S8+have small diamond lines under the glass, and their colors are not as bright as those of the previous generation, so they are generally low-key.

It is worth noting that the purple version in the rumors before is close to silver, and will show silver, lavender, light blue and other colors from different angles. Under the back cover glass, there is also a diamond pattern similar to the blue version.

Virtual Home key/fingerprint recognition/iris/face recognition
Virtual Home key: After Samsung's traditional physical home key was canceled, S8/S8+changed to a virtual key, adding touch feedback similar to iPhone 3D Touch. Its tactile feedback is no different from ordinary Android phones, but its design is worth learning from peers.
There will be no vibration prompt in normal touch, but when the full screen is displayed and the virtual key is automatically hidden, the original position of the Home key can still sense the pressure, and the function of the home key can still be triggered after slightly pressing hard. It is not necessary to call out the virtual key bar and operate again like ordinary Android, which is a complete success in convenience. Of course, it would be better if the return and multi task buttons also have pressure feedback.
In addition, this virtual button can light up the screen by pressing hard when the screen is stopped. Its use experience is basically the same as the entity's home key, which is highly praised.
Fingerprint identification: Even with the smaller S8, the position of fingerprint identification is still too high. Even if it is held by the right hand, the normal finger movement path will touch the lens glass. The S8/S8+lens glass is far more oil resistant than the surrounding glass back cover, finger It is also difficult to leave fingerprints/oil stains by deliberately pressing/scanning, but always pressing the wrong position and rubbing the lens will increase the user's "psychological pressure" invisibly. Although the fingerprint recognition speed is much faster than that of the previous generation, the usability is relatively low in such an awkward position.
Iris/face recognition: The use method, recognition rate and speed of iris recognition are not different from those of Note7. You can turn off the setting of sliding trigger in the setting, but the overall convenience and use frequency are not as good as fingerprint recognition (even though S8 fingerprint identification In such an awkward position).
Perhaps because of this, Samsung has added facial recognition. The latter can actually input facial data very quickly, and machine recognition is also very fast. It has low requirements for facial angle, and its availability is far higher than expected. It can completely replace fingerprint recognition when unlocking. Of course, the traditional fingerprint identification scheme is more convenient. After all, the device can be unlocked in the process of holding the phone in your pocket in the past. Now face recognition needs to look at the screen a little. In addition, Face recognition is less secure and cannot be used for payment operations.
screen
The biggest selling point of Galaxy S8/S8+is its screen. Although its screen share is not as exaggerated as that of Xiaomi MIX's 91.3%, it also reaches 83%. The two machines are equipped with 5.8 and 6.2 inch curved corner 18.5:9 screens, with a resolution of 2960 × 1440 (Samsung officially calls Quad HD). The PPI of the two machines reaches 570 and 529 respectively, supporting HDR, passing the UHD Alliance certification, and meeting the 4K HDR video playback standard.
In the actual test, the maximum manual brightness of the S8 screen is 365 nits, and the maximum brightness of the full white screen under strong light is about 600 nits. The basic mode is cooler than the previous color temperature, reaching about 7000K, deltaE (the smaller the better) average 2.7, the maximum is only 5. The overall data is still excellent, but it seems that the most accurate color is the music screen of S6 edge generation. For comparison, iPhone 7 is 1.6, Note5 is 1.8, S6 edge+is 2.6, and S7 edge is 2.9.
Although the function of the curved screen is the same as that of the previous generation, which is more used for installation, the 18.5:9 ratio of this generation not only makes this 5.8 inch screen phone much narrower than expected, but also makes the single hand manipulation better than other large screen phones. In addition, it allows more vertical content to be displayed on the screen, and you can swipe less pages when viewing microblog. Although the compatibility of third-party software with this screen ratio has not yet been confirmed, with Samsung's appeal, developers are expected to complete the adaptation soon (King Glory can display full screen under the LG G6 with 18:9 screen). However, in a short time of use, the Galaxy S8 does not have a serious touch problem like the S7 edge. It will only touch the notification bar by mistake. Of course, this may be because we haven't spent enough time.
system
The Galaxy S8/S8+system and the S7 edge are not very different on the whole. The main reason is that the icon has been replaced, and the original negative screen news center has been replaced with a Bixby page (called DayLite here). In any case, clicking the entity's Bixby button will also directly jump to the negative Bixby page.
Although we all know that Samsung attaches great importance to the artificial intelligence assistant Bixby, this side key is easy to be touched by mistake, especially because it is close to the "Volume Down". The screenshot and volume adjustment are often touched by mistake. The overall experience is not very good. The author hopes to customize the function of this key.
The desktop can choose the common application tile in China, or the traditional Android application drawer design (you can directly draw the drawer on the dock bar). Long press the application to pop up a function menu similar to Apple 3D Touch, but it is mainly used to manage applications.
Notification Bar and Task Management
Highly enhanced split screen function
The screen splitting function of S8/S8+and native Android 7.0 are relatively large. The default screen splitting is not the common half split, but direct windowing (probably to adapt to DeX expansion mode). The minimum ratio of the window is about 2:1 horizontally, which is just enough to put down a normal video window.
Because the screen ratio of S8/S8+is 18.5:9, even if a video window is placed at the top, the application window ratio at the bottom is normal, and the availability is much higher than that of Android peers. However, it is estimated that most people will try this function when they first buy a new machine, and the probability of daily use is still relatively low.
Advanced function, setting item, security function setting item
Even for the G950F/G955F, which is used in non mainland areas, the S8/S8+will prompt you to enable the local battery strategy (automatically hibernate various family bucket rogue software) after inserting the domestic sim card, which is worth praising. In addition, the sound effect function of S8 also has some changes. In addition to being transparent (default), virtual keys can also customize various colors and change the key sequence.
Samsung's main Bixby in the system this time cannot be used in the current system (the deadline is April 1). The object recognition function in the camera works and can normally recognize various mobile phones, watches and other objects. However, because the G950F/G955F requires Google frames and wall climbing, it cannot jump to Amazon or Google search after successful object recognition. The detailed experience of this function will be improved in the follow-up evaluation after we get the Bank of China version S8/S8+in early April. Please look forward to it.
performance
During the test, the G950F engineering machine system version is AQC9, while the G955F system version is AQBG.
The Galaxy S8 is also the top configuration of the Android camp. The 10nm Snapdragon 835 and Exynos 8895 are used. The official nominal maximum dominant frequency dropped from about 2.5G at the two SoCs to 2.36GHz and 2.3GHz respectively. In addition, the press conference only provided 4G and 64G storage versions (supporting TF card expansion), and may release the 6+128 version written by the Ministry of Industry and Information Technology in succession.
The CPU part of Exynos 8895 is 4 * Mongoose M2 (mongoose generation 2)+4 * A53, and the GPU part is up to 20 cores Mali-G71MP20@546MHz . Our G950F core is only 2.3G, while the G955F core is about 2.5G (the final mass production version may limit the main frequency back to 2.3G). In addition, the Exynos 8895 in the test machine does not have the ability of the Exynos 8890 to reach 2.6G (default frequency 2.3G) under the dual core. It is unknown whether it will be added in the mass production version.
S8+(G995F) in RAR multithreading test, The pi test also tests the performance of multi-core computing Both of them have set new records, but their RAR single thread test scores are weaker. However, because the engineering machine did not unlock the GPU run test limit, GFXBench could not load the data packet, and 3DMark could not initialize the scene, The actual results of this G71MP20 are not available yet. But this deliberate blockade, It always gives a feeling of "power consumption is not well controlled, so it is deliberately hidden".
In terms of read-write performance, the S8+(G955F) tester is 64G storage, the S7 is 32G storage, one plus 3T is 128G, and the Mate 9 Porsche design is 256G. In other cases, the larger the capacity, the better the performance. The continuous read/write performance of S8+(G955F) is amazing, surpassing the one plus 3T with larger capacity, while the random read/write performance is moderate.
The entertainment rabbit of S8+(G955F) achieved 177000 points, while the maximum power of the CPU copying machine was about 3.1W. The power consumption control was better than that of the previous generation, and the 10nm process was indispensable.

In terms of paper parameters, the IMX333/K2L2 on the Galaxy S8 is the same as the previous generation IMX260/K2L1, which is 1.4 μ m unit pixel, with dual pixel focusing, Plus F1.7 aperture and optical anti shake, The lifting point of the sensor is unknown, but the hardware parameters are still the first echelon.
The Galaxy S8/S8+models on our hands are G950F and G955F respectively, using Exynos8895 processors and Samsung's S5K2L2 sensors. Rivals include the previous generation S7 edge (8890+IMX260, Android 7.0), the belief representative iPhone 7 Plus, and the discrimination monster LG V20.

The actual imaging height of the Galaxy S8/S8+is the same. It is hard to see the difference in white balance, light measurement, discrimination and noise control. It seems that Samsung has not left a hand in the small machine. After Samsung's automatic HDR function is turned on, it can still bring about slight improvement in low light scenes. Sharpening and noise reducing smearing will be more powerful, and the fine appearance will be slightly better.

Galaxy S8/S8+ The imaging style is very similar to that of the previous generation. The white balance of the lighting scene is not as obvious as that of the previous generation, but it still tends to be red and warm. The HDR/multi frame composite effect of S7 and S8 is more obvious than that of iPhone and V20, but the contrast is still very high. With slightly higher color saturation, the S8 film is still a very pleasing type.
The image of S8 engineering machine is mainly improved in sharpening and smearing algorithms. The details and noise control are significantly improved compared with the previous generation, and the edges of objects should be more sharp and clear. Although the resolution is still far from the 16 megapixel V20, it has further widened the gap with the iPhone 7 Plus. The main problem of the iPhone is that its tolerance and discrimination decline more obviously in weak light. Of course, its imaging is also at the top level in the mobile phone industry, but its competitors here are too strong.
The contrast of LG V20 is close to that of iPhone in most scenes, but its color saturation is often higher than that of Samsung. The light metering is slightly brighter, the background noise is relatively obvious (although the granularity is very small), and the white balance accuracy is relatively low. These are problems it cannot avoid. However, the comprehensive discrimination brought by high pixels and excellent night scene algorithms is still unmatched.
parts
The original Galaxy S8/S8+flip cover protective case is more interesting. One of them is a kind of similar woven fabric surface, with the function of opening the cover and lighting the screen. There is a concave position for holding cards and cash inside. When the cover is closed, the time can be displayed through the protective cover.
The design of the transparent cover is similar to that on the top, but the front cover is translucent plastic, and there is a key logo on the side.
The official ear plugs of Galaxy S8/S8+are IG955 manufactured by AKG, which are thicker than the common official ear plugs. They are coaxial double dynamic coil structure, composed of 8mm tweeter and 11mm woofer, with wire control. The part from the connector to the earphone is made of plastic, and the part from the connector to the connector is made of braided wire. The latter has better anti winding performance and feel.
The wireless charging base has been changed into a foldable structure with a faux leather surface, and the disc can be pushed up (similar to the sliding cover of Nokia N97). The bottom cover also has a cooling fan and a cooling grille.
DeX docking station on the left and wireless charging base on the right
DeX docking station provides dual USB, network cable interface, HDMI and Type-C interface (for power supply), built-in cooling fan, Same sliding cover design , you can also fast charge your mobile phone during desktop expansion. After connecting to the base, the mobile phone will be forced to blank the screen (save power and reduce heat?). It takes about 5-8 seconds to switch modes by plugging and unplugging the chassis.
Multi task interface
After such martyrs as Motorola and Nokia Lumia, the ideal of "mobile phone as PC host" has finally reached the point of availability here in DeX. After the monitor is connected, the desktop will switch to a flat panel mode. Its essence is not very different from the ordinary Android launcher. The bottom left corner is the three Android King Kong buttons and application drawer, and the desktop is an application shortcut.
Because it is originally an Android app, it is relatively smooth to open more apps. Except for the specially adapted Microsoft Office suite or tablet app, other apps are basically simple stretch and zoom, and the window is displayed at 16:9 by default. Many application windows have to be manually adjusted to the common vertical screen mode of the phone to have normal availability. In addition, the current version of the system does not have the function of automatic window splitting (such as the common left and right splitting on the Windows platform), so you have to manually move and adjust the size of the window, and the desktop can not place pictures, documents and other files like a PC. DeX mode can be used to deal with simple web browsing and document editing, but there are still many areas to be improved and strengthened.
