The smartphone market in 2016 was a bit special. Apple's performance in the past was declining (Q3's worst financial report in 13 years), while its rival Samsung was in a tough growth this year (the Q2 performance is expected to be the most in two years). it is good). The outside world believes that the Samsung Galaxy S7/S7 edge is an important reason. However, we all know that Samsung adopts the dual flagship policy every year. Can this year's Samsung Galaxy Note7 be as powerful as the Samsung Galaxy S7/S7 edge at the beginning of the year?
At 23:00 (Beijing time) on August 2, Samsung released the new Galaxy Note7 in New York. In addition to the regular hardware upgrades, this generation of models joined Samsung's own hyperbolic screen and Samsung Galaxy. The highly acclaimed 12-megapixel Dual Pixel camera in the S7/S7 edge also supports iris recognition technology. With its powerful performance and numerous new selling points, Samsung Galaxy Note7 has become a well-deserved Android machine. PS: This time participating in the evaluation is an international version.
Hardware parameter
Samsung Galaxy Note7 upgrade is relatively large, equipped with Samsung's own Exynos 8890 processor (4x2.3GHz + 4x1.6GHz), while the national version of the Qualcomm Snapdragon 820 (2x2.2GHz + 2x2.0GHz), with 4GB RAM + A combination of 64GB ROM supports up to 256GB Micro SD card expansion. The network supports LTE Cat.12 (depending on the region), and according to the network information published by the Ministry of Industry and Information Technology, the Bank of China version supports dual-card dual-standby full-network 4G.
The 5.7-inch 2K screen is a hyperbolic design with a Super AMOLED panel. The front of the mobile phone is equipped with a 5 megapixel camera, and the rear is equipped with a 12 million Dual Pixel camera. The aperture is F1.7. In addition, Samsung Galaxy Note7 also supports Samsung Zhifu (MST), NFC, iris recognition, S Pen, wireless charging, IP68 waterproof.
Iris unlock
Appearance: comprehensive dustproof and waterproof + hyperbolic screen design
Appearance, Samsung Galaxy Note7 body design and the previous exposure of the renderings basically match, continue the double-sided glass body design, and added a hyperbolic screen, the overall contour of the fuselage is similar to the Samsung Galaxy S7 edge. In addition, new features such as the blue color scheme, the Typc-C interface, and the iris recognition have been rumored.
On the front of the fuselage, the Samsung Galaxy Note7 still uses a 5.7-inch 2K resolution screen. It is worth mentioning that the design of the double-sided screen is added. The Samsung Galaxy Note7 has a higher screen ratio than the Samsung Galaxy Note5, and the visual experience is even more shocking. 
On the back of the fuselage, the Samsung Galaxy Note7 still uses the back cover of the 2.5D curved glass, and the camera, flash and heart rate sensor are arranged in the same way as the Samsung Galaxy Note5. 
However, compared to the Samsung Galaxy Note5, the appearance of the Samsung Galaxy Note7 has changed a lot, the overall design has become more rounded. In addition, Samsung Galaxy Note7 adds a blue version, which looks more elegant and natural. Therefore, the Samsung Galaxy Note7 has a total of four color schemes of gold, black, blue and silver. 
It is worth mentioning that the blue color version of the Samsung Galaxy Note7 screen panel, and the S Pen stylus color are unified into blue, while the metal middle frame is gold. 
In addition, the color of the gold, silver and black metal middle frame is the same as its body color. Samsung Galaxy Note7 sleek body design is mainly reflected in the "hyperbolic screen +2.5D glass back cover", the curved glass on the front and back sides are symmetrical, thus polishing a more rounded border. 
Earlier there was news that the Samsung Galaxy Note7 added iris recognition, so the top of the front panel of the phone has an opening. However, there are only three openings visible on the Samsung Galaxy Note 7, and the results for the four color versions are consistent. As for the iris unlocking experience, it is very fast and convenient. 
In addition, because the Xiaobian experience is the international version of the Samsung Galaxy Note7, so the front still retains the Samsung logo. According to the design of the Samsung Galaxy S7 series of the National Bank version, the Samsung Galaxy Note7 of the National Bank may also remove the logo on the front of the fuselage. 
The design of the body interface and button position, Samsung Galaxy Note7 compared to the Samsung Galaxy Note5 has no obvious changes, but the Samsung Galaxy Note7 uses the design of the type-c USB interface. In addition, the Samsung Galaxy Note7 is still designed with a dust-proof and waterproof design. The principle is that the inside of the interface of the fuselage is actually sealed, leaving only the metal contacts exposed. The exposed metal contacts also use a hydrophobic nano-coating, while the Samsung Galaxy Note7 also has an IP68 rating, which can theoretically be soaked in 1.5 meters of water for half an hour. More surprisingly, the S Pen also supports waterproofing, and the wireless charging device also supports waterproofing, which is fully waterproof.
In terms of body details, the Samsung Galaxy Note7 is very polished, such as the seam between the screen panel and the metal middle frame. The card slot should be faceted. The Samsung Galaxy Note7 is designed with a single card tray and a card slot. It supports the Nano SIM card and the Micro SD memory card. 
Compared to the Samsung Galaxy Note5, the length and thickness of the Samsung Galaxy Note7 are actually slightly increased, but the width of the body is significantly reduced, which may be due to the design of the hyperbolic screen. It is worth mentioning that the battery capacity of the Samsung Galaxy Note7 has increased to 3500mAh. 
However, although the Samsung Galaxy Note5 is actually thinner than the Samsung Galaxy Note7, the Samsung Galaxy Note7 benefits from a sleek body design, which is much thinner than the Samsung Galaxy Note5. In addition, the body is more rounded, and the smaller width of the Samsung Galaxy Note7 is also better reflected in the feel. 
In addition, the Samsung Galaxy Note7 S Pen stylus design has also been greatly improved, such as the nib design is more slender, and equipped with a 4096-level pressure (Surface Pen used in the Surface Book is only 1024 pressure) . 
In addition, Samsung Galaxy Note7 also adapts to the S Pen stylus function at the system level, for example, in the standby display interface, you can directly use the S Pen stylus to record important information. 
It is worth mentioning that the Samsung Galaxy Note7 has a wealth of accessories to choose from, such as in addition to our common protective leather case, Samsung Galaxy Note7 also adapted to expand the camera function of the protective shell, as well as external physical keyboard and so on. 2 Samsung Note7 Review: iris recognition, dual-core full-pixel camera
System experience: iris recognition is a highlight
The Samsung Galaxy Note7 system also uses the familiar TouchWiz UI style, based on Android 6.0.1 optimization. The Samsung model that I have used in recent times is getting higher and higher in localization level (for example, there is optimization of red packets), I believe that the Samsung Galaxy Note7 of the National Bank version will be more grounded on the system than before.
The phone has built-in Flipboard reading software, users can choose the news source they are interested in, they will appear in magazine-style layout, and the animation effect brought by the page switching is very gorgeous. 
On the way the phone is unlocked, the machine offers three options. The first is the password unlock, the second is the fingerprint unlock, and the third is the iris recognition. The iris recognition function is a big selling point of this Samsung Galaxy Note7, which is introduced below. 
The iris is part of our eye, which remains constant throughout the life course of the fetal developmental stage, and the iris recognition technology is based on it for identification, so there is no doubt about safety. Since iris verification does not leave any physical imprint on the Samsung Galaxy Note7, it cannot be copied, so the iris is one of the safest ways to protect data. 
In the security settings, we can see the iris recognition function. After that, the system will remind you how to enter the iris information. For example, please do not wear glasses during this process. 
The progress of the entry is displayed on the screen. After a short period of time, the iris information is recorded in the mobile phone. 
Users can store their important files in a secure folder, which can only be accessed by identifying the iris. During the process of use, if the recognition is wrong, the phone will prompt you to wipe the top camera area. 
In addition to iris recognition, another highlight of the Galaxy Note7 system experience is clearly handwriting. Now that the Note series has evolved to the 6th generation, the S Pen has matured and the system has features specifically designed for the S Pen. 
The machine also inherits the Samsung Galaxy Note5's off-screen and fast-write function. When the S Pen is pulled out in the off-screen state, the system will directly display the handwriting interface, and the black background makes good use of the characteristics of the AMOLED screen (because of the self-illumination principle). , when the black image is displayed, the corresponding screen pixel can be turned off), which is beneficial to extend the battery life. In addition, the new S Pen supports up to 4096 pressure impressions, and the user's handwriting strength can be felt with a slight change, and the writing is more natural and smooth. 
Of course, with S Pen and more gameplay, click on the S Note function in the system application, there are many creative spaces, such as font color, handwriting type and writing background, etc., users can choose their favorite style. Camera Experience: Dual-Core Full-Pixel Sensing Technology
Apple iPhone 6s/6s Plus has a poor performance on the camera, even surpassed by domestic models (such as Huawei P9/P9 Plus, one plus mobile phone 3, etc.), while the Samsung Galaxy S7/S7 edge is almost identical in the Android machine. Is a comprehensive lead.
This Samsung Galaxy Note7 also uses a 12-megapixel Dual Pixel camera (pixels are the same as the S7/S7 edge, but the specific sensor model has to be confirmed), the pixel size is 1.4μm, and the front is 5 million pixels, all have The largest F1.7 aperture in the mobile phone, the rear camera supports optical image stabilization. 
Normal phase focus; full pixel dual core focus
Dual Pixel's Chinese name is full-pixel dual-core sensing technology, which was first applied to the Canon SLR 70D to improve imaging focus and tracking speed.
Dual-core full-pixel can be easily understood as an additional photodiode
Full-pixel dual-core refers to dividing all the pixels in CMOS into two (dual-core), and two pixels can be independently imaged, and then the computer can calculate the subject and us by comparing the difference between the two independent images. The actual distance for fast focus and tracking focus.
In the shooting interface, the Samsung Galaxy Note7 is not much different from the Samsung high-end models in the recent period, and it is easy to switch other functions by sliding left and right. 
As you can see from the official proofs, the Samsung Galaxy Note7 has a powerful shooting performance, and with its fast focusing speed, the moving picture is easy to capture. 
In the low light proofs, the picture maintains a high degree of purity, continuing the advantages of the Samsung Galaxy S7/S7 edge, which is quite expected. The following is a new version of the real proof. 
Thanks to the application of full-pixel dual-core technology, the Samsung Galaxy Note7 has a faster focusing speed. Whether it is shooting close-range objects or long-distance, it is basically "what to call".
In the daytime proofs, Samsung Galaxy Note5 continues the characteristics of the high-precision sharpness of the predecessor model, and the overall look and feel is more pleasing to the eye.
In the low light environment, the performance of the Samsung Galaxy Note7 is as good as ever, especially in the noise control performance (the picture is difficult to detect under normal size), allowing users to shoot boldly in poor lighting conditions.
