It continues the design style of the previous generation and makes a lot of detailed improvements. What improvements has Galaxy S9 series made compared with Galaxy S8 series? What has been improved?
Appearance aspect
Samsung Galaxy S9 series has not been redesigned in appearance, and the details are not particularly changed. It continues the 18.5:9 scale curved surface visual frameless design of Galaxy S8, and also uses double-sided glass and metal frame. In detail, the Samsung Galaxy S9 uses 5.8 inches, while the S9 + uses 6.2 inches. The front forehead and chin of the overall fuselage are narrower than those of the S8. The screen is the same as the S8 series (super AMOLED screen), and the same resolution is still designed with 3D Corning's fifth generation glass + 7000 series aluminum alloy frame. However, the screen adds the adaptive contrast enhancement function to make the screen in strong light Better experience.
There is no big difference on the side of the body. There is still a Bixby assistant shortcut key, which keeps the 3.5mm headphone hole. An AKG professional music headset will still be attached to the original accessories.

As for the right side of the lens, there are flash and heartbeat sensor (which can measure heartbeat, blood oxygen and other values).
From the aspect of overall length, width and height, the body size of Galaxy S9 is much smaller than that of S9 +, if compared with the 16:9 screen mobile phone, the width is about 5 inches and 5.5 inches respectively, which is more comfortable than that of Galaxy S9 in hand grip; while S9 + is not suitable for single hand operation, with an overall thickness of 8.5mm, except for the difference in screen size, it looks like other things There is no difference, but the S9 series is slightly thicker than the S8 series, and the body weight and size are just right.

Camera aspects
Pictures from the Internet
Samsung Galaxy S9 adopts the same single shot design scheme as the previous Samsung Galaxy S8 single shot design scheme, with the front 8 million pixels + 12 million pixels lens; however, Samsung Galaxy S9 + adopts the dual shot scheme, with the front 8 million pixels camera, the rear 12 million pixels (F2.4 large aperture) + 12 million pixels (long focus lens) lens, f1.5/f2.4 intelligent variable large aperture, supporting PDAF focusing to And dynamic focus, support double OIS optical anti shake, can be used for optical zoom and portrait photography with defocusing background, or use the focus function to capture dynamic objects, all support super fast full dual core sensor.
Most importantly, the Samsung Galaxy S9 + rear dual camera lens is very interesting, even with 10 times digital zoom and shallow depth of field. When the camera switches between F / 2.4 (in case of sufficient light) and F / 1.5 (in case of dark and low light), when switching the aperture, you can see the process of enlarging and shrinking the aperture of the camera at the same time, and you can also judge whether to enlarge the aperture through light intelligence. In the ultra dark environment, you can not only adjust the aperture automatically, but also support multi frame noise reduction technology Surgery. This technology is not the first in Samsung Galaxy S9 series. It was first seen in Samsung's 10000 yuan Samsung w2018.
Samsung S9 series also supports 720p slow motion video shooting of 960fps, automatically detects and starts the slow motion mode, and can choose 35 different background music, easily create / edit / share GIF motion pictures, and can also be used as dynamic mobile wallpaper, which is not a black technology.
Performance aspect
The configuration of Samsung Galaxy S9 / S9 + is the final highlight and the differences are mainly reflected in the screen size, battery capacity, memory and camera. It is equipped with a snapdragon 845 / exynos 9810 processor and a 10 nanometer process eight core processor. The Samsung Galaxy S9 has a built-in 4GB storage + 64GB / 128GB / 256gb storage combination, while the Samsung Galaxy S9 + built-in 6GB storage + 64GB / 128GB / 256gb storage combination can support up to 400gb of expandable memory.

It supports USB type-C interface with positive and negative pluggable, and continues the previous iris recognition, Bixby, NFC and other supporting functions to run Android 8.0 operating system.
The face recognition technology of Samsung Galaxy S9 / S9 + mobile phone has been greatly improved. Besides fingerprint recognition and 2D face recognition, it also has a special iris recognition ability. At present, Samsung's iris scanning + face recognition technology has been combined with the artificial intelligence scanning technology (intelligent identification) developed by Samsung, which is not to improve the security of identification, so that mobile phones can choose different identification systems according to the strength of light source. For example, if you choose face recognition (still in 2D shape) in a place with too much light, it can only be used to unlock the screen. If the light is weak, iris recognition is used instead. As long as the iris function is turned on, the face or iris recognition can be intelligently selected according to the recognition conditions.
other aspects
On the Bixby vision experience, the Samsung Galaxy S9 series has added the function of AR direction and instant translation in the original mode. As long as the camera image is aimed at foreign language, it can be translated instantly, just like Google's instant lens translation method, but Bixby vision supports more languages, such as Korean translation of Chinese and Spanish translation of Chinese. Samsung also revealed that in the future, Bixby vision will integrate camera application functions through augmented reality mirror and deep learning technology.
In addition to the original filter, map and other functions, Samsung Galaxy S9 series adds a new ar map, which can detect more than 100 special effects on the face through the lens. It is machine learning to analyze the user's 2D image, and then use 3D dolls to imitate your facial expression, which is similar to the 3D dynamic expression map function of Apple iPhone X. The new ar map can also create a special virtual doll, such as changing hair style, accessories, clothing, etc. after completion, it can also be made into a GIF dynamic map, which can also be used as an expression pack in social communication software such as information, or output ar map movies.
Samsung also launched a new base accessories for Samsung Galaxy S9 series. In the past, it used to connect HDMI cable through the bottom, and put the mobile phone screen and the connected computer interface on the external screen. At the same time, it can also connect wireless mouse and keyboard. And the new base can make the mobile phone as a touchpad and wireless keyboard, which will be more convenient in operation and save the tedious wireless mouse key equipment.
