Whether it is Apple or Samsung, although the confidentiality work has increased at the same level, the high attention has made their flagship machine seem to have no way to go before it is released. So when you officially see the S9 series, you can't feel the "surprise" that it brings.
As the second generation of Samsung's "full-view full-screen" mobile phone, Galaxy S9 (hereinafter referred to as S9) compared with S8 upgrades, which users are suitable for, may be what we need to say.
Strictly speaking, S9's screen is higher than S8, retaining the left and right curved surface without borders and top chin design, but Samsung's statement is that the upper and lower forehead is narrower.
However, from this point of time, only the "removal of the forehead chin" seems to be a further upgrade, and therefore, the S9 is basically the same as the S8 in the front, but it looks more detailed, and even the opening of the iris sensor is more concealed.
The back of the S9 is still fine-tuned compared to the S8 – the lens and fingerprint are changed from landscape to vertical. The benefits are obvious, your fingers will unlock the screen in a more comfortable position; for a high-frequency operation, this small change is really practical.
Especially for the 6.2-inch version, the answer we gave last year when evaluating the S8+ fingerprint unlocking experience was that it was harder to touch, and this year there is no need to worry about it.
Although the answer to the fingerprint of the screen was not delivered as expected, Samsung surrendered a more satisfactory facial recognition on the S9, but it may be necessary to put a quotation mark on the "face recognition".
"Iris recognition needs to scan the eyeball, so the phone and the eyes ensure a certain distance and angle, which is more difficult to use; on the other hand, face recognition is as long as the lens is aimed at the face; but it is only by the front lens, the light is The environmental requirements are high. Therefore, the stability under low light is much worse. What is more embarrassing is that although these two methods seem to have complementary advantages and disadvantages, they cannot be opened at the same time."
.
We mentioned the most embarrassing part of the S8 facial recognition solution in the S8 evaluation last year - the two positive creature unlocking methods that should be complementary can not be opened at the same time.
S9 obviously draws on experience, or is more mature in technical solutions. This generation of products can intelligently determine where to open facial recognition, when to open the iris recognition of the glasses, and not only based on light judgment, such as the iPhone X can not recognize the mask, Samsung will automatically identify the mode Adjustment.
Although this seems to be a small improvement, behind the scenes is Samsung's many years of exploration of sensor technology.
Once upon a time, Samsung once represented the highest level of Android photography, but in the past two years it has been caught up by other manufacturers.
Looking back at the S8, although it is still the first camp of the Android camp, but in the performance of the details of the photos, especially in the low light, the photo is more "small", it is a small short board.
So this time Samsung joined the fast multi-frame synthesis technology that is widely used, and uses the unique full dual-core speed sensor technology to instantly synthesize 12 photos to improve the expressiveness of details. Thanks to the full dual-core speed sensor, the S9 can perform slow-motion playback at 960fps.
Upgrading to photos under low light Samsung not only relies on multi-frame synthesis, but also adds hardware optimization. In the Samsung W2018 this 20,000-yuan business flagship Samsung's F1.5 large aperture completed the first show, this time it is the consumer machine flagship S9.
Through the identification of the metering environment, Samsung will automatically choose whether to open the F1.5 large aperture to increase the amount of light, and through multiple synthesis techniques to capture the details that are not visible to the naked eye.
All in all: "The invisible to the naked eye" is the definition of this generation of Samsung to S9 in the picture. Based on this better low light effect, 960fps slow shooting specific effect, in addition to the experience link we also need to compare in the detailed evaluation.
Because technology has new products, because new products have new user needs; for example, just after the Spring Festival, many people have received Animoji New Year animations with iPhone X. For the Samsung S9, which has been used to mark the iPhone X before it is released, this kind of function is naturally indispensable.
Samsung S9 called this new feature AR Emoji, compared to Apple Face ID to use the structured light of the face to directly draw 3D dynamic images, Samsung chose to "analyze user 2D images through algorithms and draw more than 100 facial features, create 3D dynamics in the form of a 3D model that can react and mimic user expressions in real time. The principle is different, but a similar effect is achieved.
Specific to the function, Samsung S9 can draw a cartoon character image, and support the cartoon image to change, skin color, hair style modification, recorded video animation can also be shared in third-party applications. As for whether this feature will appear on the flagship S8 of the previous generation, we do not know.
Bixby is Samsung's attempt for artificial intelligence assistants for many years. In addition to the commonly used speech semantic recognition, Samsung has also made a small upgrade to image recognition on this generation of products - it can translate the content appearing on the image in real time, without like Translate the photos first and then translate them.
How to put AI, a technology that is not well reflected, to users, Samsung has found a good function point, and it is really a pain point for users who travel.
Finally, let's briefly talk about the difference in hardware between the two devices. On the whole, Samsung S9 and S9+ use a 10 nanometer process 8-core processor; S9's memory RAM is 4GB, S9+ is 6GB, and the body memory capacity is 64GB. The screen size is 5.8 inches and 6.2 inches.
The Samsung S9 is equipped with an 8 megapixel lens with a front F1.7 large aperture and a 12 megapixel F1.5/F2.4 large aperture rear main lens with a super fast full dual-core sensor. The difference is that the S9+ uses rear dual camera, and the other telephoto lens is also 12 million pixels.
The rest of the Samsung S9 body battery capacity 3000 mAh, while S9+ is 3500 mAh; using iris scanning, fingerprint scanning, facial recognition three biometric technology; support dual card dual standby and body storage expansion.
If the iPhone X is an innovation made by Apple after many years of silence, then the Samsung S9 is a perfect repair of the company after years of technical rush.
There is no imaginary under-screen fingerprint, but it unlocks the most complete face unlocking ability of the Android camp; the upgrade of the photo sensor also makes S9 seem to return to the first strength of the Android camp photo; AI and AR hotspot functions It was not pulled down on the S9.
In short, this is an update that caters to new market trends. Although users of handheld S8 don't necessarily have many reasons to upgrade, S9 will be a good choice for those who want to choose the best one in the Android flagship.
