IT168 on-site experience Global smartphone shipments in the second quarter of 2016 were 343 million units, and the favorable reviews of Samsung Galaxy S7/S7 edge made Samsung firmly the leader in shipments. Taking over the battle flag in the second half of the year is naturally the Samsung Galaxy Note series, which focuses on the "pen" application. According to the release time, this year's Samsung Galaxy Note7 is earlier than before. It will be released on August 2 (US time). Maybe Samsung hopes to take advantage of the popularity and launch the product earlier to seize the opportunity. The author believes that this product has attracted so much attention for several reasons: First, it is the originator of large-screen mobile phones. Secondly, the core functions of the Galaxy S series can be retained and problems can be improved. For example, do you still remember that the Galaxy S4 had an eye-tracking function? After this function was launched, many people complained that it was useless, so this function was removed from the subsequent Galaxy Note3. Third, there are many large-screen smartphones in the consumer market, but not many products are equipped with stylus pens. Moreover, the charm of S Pen lies not only in its high sensitivity and smooth writing, but also in its ability to bring a better experience when paired with built-in applications. How do these points perform on this generation of Galaxy Note7? Let’s take a look at the author’s first-hand experience at the scene.
The appearance of double-sided glass with metal frame has further evolved
Since the Samsung Galaxy Note series is equipped with a curved screen, it will launch two different versions. This may be due to consumers’ demand for curved screens. There is only one version of this year's Galaxy Note7, which is the Galaxy Note7 with a hyperboloid screen design. It is the first to use Corning's fifth-generation Gorilla Glass as the mobile phone panel, with a screen size of 5.7 inches (resolution 2560x1440 pixels). In terms of other hardware configurations, 6GB of memory is not used, but a 4GB 64GB combination is chosen. In terms of color, as previously exposed, there are four colors: black, silver, blue and gold, of which blue is very eye-catching.

Starting from Galaxy Note5, the design of double-sided glass with metal frame appeared for the first time in the Galaxy Note series. In terms of appearance, Samsung Galaxy Note7 is undoubtedly a step forward. It still uses a double-sided glass and metal frame design, retaining the overall structure and outline of the previous generation design. The glass hot-bending molding technology makes the surroundings more rounded.

In addition, this time Samsung Galaxy Note7 supports IP68 waterproof and dustproof functions, and the S Pen also supports it. The interface has also been upgraded to a USB Type-C interface. The control of other parts of the body is also very good, and the precise assembly process makes the entire phone look like a work of art.

In terms of details, Samsung Galaxy Note7 has adjusted the edge transition to greatly reduce the cutting of the metal frame. area, the curvature of the curved glass extends to the metal frame of the fuselage, making the edge of the machine smoother and the two materials more integrated. The thickness of the fuselage is approximately 7.9mm (the previous generation was 7.6mm), and both sides of the back are curved. The hand feel is significantly improved when holding it.

New design of S Pen Interpretation of the four major functions
Through the appearance introduction, you should see that the Samsung Galaxy Note7 continues some of the advantages of the Galaxy S7 edge’s industrial design, as well as its waterproof and dustproof capabilities, but for the Galaxy Note series, “S Pen" is its essence. Next, let's take a look at its evolution and new functions.
Samsung S Pen is a collaboration between Samsung and the well-known tablet brand Wacom, and continues the press-to-pop design of Galaxy Note5. The pen tip is about 0.7mm, which is very slender, and the pressure sensor is increased by 14 (official data). As for the working principle, the pen tip has a pressure sensor, which can simulate the images written with different pressures according to the amount of force you exert.
▲The S Pen equipped with Samsung Galaxy Note7
After the introduction of the hardware upgrade, the author will introduce the new functions of this S Pen. Screen-off quick writing is no stranger to those familiar with Galaxy Note5, and the Always on Display screen function (AOD) is no stranger to consumers familiar with Galaxy S7/S7 edge. However, under the catalysis of the S Pen equipped with Samsung Galaxy Note7, What new experience will there be when these two functions are combined?
▲Always on Display screen function
The author will introduce it to you in detail: the AOD function can display the time and calendar by default. When the screen is black, pull out the S Pen and immediately enter the screen-off quick writing Interface, you can record information directly on the phone screen and customize it to display on the lock screen. This allows you to see recorded notes without having to open the entire screen. It truly extends the memo and reminder functions from the real world to the virtual world.
Another function that I don’t know how to translate accurately is Samsung named it smart select. To put it simply, when the user sees an interesting video animation while browsing the web or Weibo, the user can use the S Pen to select the video area for 15 seconds of screen recording, and then a Gif will be generated. Users can also modify the Gif image twice through the picture software, such as adding a logo or writing, etc. It feels like a large number of emoticons are coming towards the author...
▲Smart select can select the video area to take screenshots and Secondary modification and social sharing
Another small function is the translation and amplification functions that have been exposed for a long time. As you can imagine, sliding the S Pen over the word that needs to be translated can be translated, because there is no need to call up a special application, which will greatly save time in translation. The second new feature is magnification. This is easy to understand. When you need to enlarge a certain area on the screen, point the S Pen there.

When it comes to the iris function supported by Samsung Gaxlxy Note7, the author quoted an article written by a colleague two days ago to introduce it in detail. This black technology.
The iris recognition added to Samsung Galaxy Note7 has become a new feature that has attracted much attention from consumers. After all, there are currently relatively few products equipped with this feature. Thinking of the eye-swiping unlocking lens in science fiction movies, and this scene will soon be realized on mobile phones, it is inevitable to feel a little excited. So what kind of technology is iris recognition, and what can it bring to us in the future? Let’s take you through this cool black technology.
▲The iris recognition function added to Samsung Galaxy Note7
What is iris recognition?
Before talking about specific iris recognition, we must first understand what iris is . Simply put, the human eye structure consists of three parts: sclera, iris, and pupil. The iris is the ring-shaped part located between the black pupil and the white sclera. It is the dark part of the eyeball around the pupil. It contains a large number of unique features, including interlaced spots, filaments, crowns, stripes and other details. It is complex. The extent is evident.
Irises have a one-to-one correspondence with each person, and iris recognition technology has been developed to identify identities by scanning iris. According to research, iris recognition is 10,000 times more accurate than fingerprint recognition and 100,000 times more accurate than facial recognition. It is widely considered to be the most promising biometric authentication technology in the 21st century and has been used in security, national defense, e-commerce, etc. fields play an important role.
It was the first iris recognition mobile phone
As the technology becomes more mature, iris recognition algorithms and image collection modules can be easily implemented on the mobile terminal. In a world where information security is increasingly valued, Today, the emergence of iris recognition mobile phones is a matter of course. Fujitsu ARROWS NX F-04G, this is the first smartphone with iris recognition. Later, Microsoft's Lumia 950XL also added the Windows Hello iris scanning unlocking function. However, this model suffered from the poor mobile ecosystem of Windows, and the iris recognition time was too long (about 2 seconds), and it did not cause much trouble.

Some domestic manufacturers are also making a fuss about eye-swiping. Mobile phones produced by ZTE and vivo have added eyeprint recognition functions, claiming to be safer. Sexually one step further. In fact, there is a huge difference between eye pattern recognition and iris recognition. Both the security level and the recognition rate are lower than that of iris recognition. Eye pattern recognition is just a side effect of iris recognition.
This time Samsung Galaxy Note7 is a little different
It should be said that there is a precedent for the application of iris recognition on mobile phones, but for various reasons, it has never caused a sensation. But this time the Samsung Galaxy Note7 is different. As soon as the news came out, it triggered a lot of heated discussions. Even the stocks of companies related to iris recognition became popular. This is due to Samsung’s appeal in the industry, and on the other hand, it is also the iris of the Samsung Galaxy Note7. Recognition is really something different.
▲An iris scanning patent document in the name of Samsung
Samsung Galaxy Note7 will be equipped with a specific iris recognition system, which consists of three parts. First, the phone will use ordinary The front camera determines the user's face, and then a specific light source emits infrared rays. A camera specifically responsible for iris scanning senses the characteristics of the iris through infrared rays to complete the scanning and recognition functions.
▲Iris recognition lock screen interface
In terms of specific applications, the iris recognition supported by Samsung Galaxy Note7 can not only unlock the phone, but also access a newly added secure folder. It can store the owner's private files, photos, and even third-party applications, fundamentally providing a "container" solution to isolate the mobile device's office use and personal life use. When experiencing iris mobile phone unlocking, you need to maintain a distance of 25-35 centimeters between your eyes and the phone. The unlocking speed is quite fast and the recognition rate is also high. Compared with the recognition experience of existing products, it is significantly improved.

To sum up, the fingerprint recognition industry is mature and the application ecosystem is complete, so it is still the main choice for mobile terminals. As a more advanced existence, iris recognition will continue to be improved and provide strong support for high-level security authentication. This Samsung Note7 attempt, in the author’s opinion, is more of a technical display, expounding Samsung’s thinking on future mobile security certification. After determining the development direction of the dual recognition mechanism of fingerprint and iris, in addition to optimizing the performance of the two, how to specifically coordinate the application scenarios of the two so that the technology can truly bring convenience to users will be a problem that Samsung and even the entire industry need to solve in the future. .
Capacity upgrade and battery life increased to 3500mAh
Support wireless fast charging and ultra-fast charging functions, which can maximize the use of users' scattered time for charging and also bring a faster charging experience , which can be said to be one of the best solutions for the smartphone industry currently encountering battery bottlenecks. In terms of capacity, the battery capacity is larger, and the battery capacity of Samsung Galaxy Note7 has been increased to 3500mAh.
Front 5 million pixels and rear 12 million pixels camera combination
Samsung Galaxy Note7 uses the same camera configuration as the S7/S7 edge, with a front 5 million pixels and a rear 12 million pixels Pixel camera, the aperture is increased to f/1.7, supports Dual Pixel technology, and 100 pixels are used for focusing. How to understand this technology, full-pixel dual-core focusing, splits each photodiode into two, and can capture two parallax images at the same time. Full-pixel dual-core focusing uses signals from these two images to complete phase difference detection autofocus, and can also be output as a single pixel. Since one pixel can perform both autofocus and image capture functions, the number of pixels used for autofocus can be increased while maintaining image quality.

New VR, new protective cases and accessories
Because the interface has been upgraded to USB Type-C, Samsung Galaxy Note7 will not be able to It is compatible with the existing Gear VR, so Samsung will launch a new Gear VR, and the new Gear VR will support older devices up to the Galaxy S6. Samsung has equipped it with an adapter. Users only need to change the plug of the MicroUSB interface to the Gear VR when using it.
▲MicroUSB interface conversion plug
The new Gear VR has several main changes: first, the color changes from white to black and blue; second, the adjustment strap is longer, making it easier to wear. Third, add an independent HOME button to directly return to Oculus Home with one click; finally, there are some other features such as touchpad adjustment and anti-interference design for left and right eyes, etc.
▲Added anti-interference design for left and right eyes
