I. UnpackingThe iconic threshold is reached , it's useless for Zhang Aunt’s box.
Open the carton reveals the protagonist red rice note4, there is a public measurement notice below
Intimately wrapped a lot of layers of bubble film, enough for a long time I squeeze a bubble
The mobile phone box does not say anything, the basic is to change the photo, change the direction, change the number .... (The golden light seems to be lighter, the monkey king is not ink?)
Mobile phone body, silver white full Netcom high version
5v2a charging head
Usb data cable

Two. Appearance detailsThe red rice note4 screen is covered with a 2.5D arc edge glass. The top of the fuselage has a perfect symmetrical design. From left to right, it is light distance sensing, earpiece, front camera and hidden breathing lamp. (Now more and more domestic manufacturers use this kind of styling will soon become a model)
The bottom of the fuselage also uses a symmetrical design, the middle charging port is still a conventional USB interface, and does not use Type-C, symmetrical speaker on both sides of the charging port, only the right speaker out loud
Compared with red rice note3, the metal texture is much stronger
The curvature of the sides of the back of the body is very beautiful design 
The top of the fuselage from left to right are the headphone jack, infrared sensor and noise reduction microphone.
The physical buttons are all designed to be on the right side of the phone. They are the volume “+†“-†and the power button.
Card slot is on the left side 
Cato is still the second choice of the design, you can choose to put a micro sim plus a nano sim card; or a micro sim plus a memory card
The back of the fuselage from left to right are 13 million pixel camera, dual color temperature flash and fingerprint recognition.
On the back, the red rice note4 back cover is no longer a three-stage metal, but an all-metal backshell, using a 9-channel CNC diamond cutting process similar to the red rice pro. The body design uses a midline symmetry, and feel and vision are better. It can be called the flagship craft of thousand yuan machine.
Since it is a white panel, it is of course necessary to talk about black borders. Red rice note4 bright screen after the law, the black side is definitely not narrow, but a lot stronger than the ancestral black side of the chrysanthemum low-end machine, but not as id without borders need to bring your own oxygen cylinder
No harm without comparison, the above is the red rice note4 below is the charm blue note3
========== I'm a gorgeous dividing line ==========
III. System uiRed rice Note4 equipped with miui8 based on Android 6.0, compared to the previous miui7 in addition to a major change in the color, but also more applications such as double-scanning and other practical new features
Because it is a development version of the system, the mobile phone has pushed two upgrades within a week
The color of the drop-down menu is much larger than that of the previous miui7. The default is a single page notification bar, but it can be changed to the original double page mode in the settings. The more interesting point is that the drop-down menu will change color with time, weather, location, etc.
The boot can be shipped around 1.5g
The multitasking interface is card type by default. Click the upper right corner to change back to the small icon. Of course, the same method of supporting miui7's two-finger switch view is also supported.
Authorization management comes with open root privileges 
Fingerprint entry is fast. Unlocking is basically the same as before note3 is seconds off
Red rice note4 can finally pay Alipay fingerprints! This practical function must be praised 
The full-featured calculator adds currency conversion, mortgage calculations, personal income tax, uppercase numbers, scientific calculators, length conversion, area conversion, volume conversion, temperature conversion, speed conversion, time conversion, and weight conversion. For example, when we travel abroad, Haitao needs the exchange rate of foreign currency, the calculator supports the conversion of multiple currencies, and the exchange rate is updated in a timely manner. The conversion is intuitive and quick. For the majority of office workers, calculating payroll taxes, bonus benefits, mortgage payments, etc., have also become clear and meaningful.
scan it
Open the "System Tools" folder, you can see the sweeping icon, you can open the new sweeping interface, and the camera is as simple and beautiful. You can see that there are six functions such as scanning, photo purchase, translation, scanning, scanning business cards, scanning documents, etc.
Commodity scan code. After the barcode scanning of the product, the price can be compared immediately to help you find the most suitable product. 
Photo purchase. Some products do not have bar codes. What should I do? Faced with a physical shot, you can directly Taobao, recognition rate is OK 
Long screenshot
Miui8 added a long screen function, not only a regular scroll screen, the user can adjust the speed and position of the long screen by hand sliding, find the area that needs screen capture, and achieve accurate screen capture
Apply double open
The miui8 application is not only suitable for acoustic applications, but also for third-party applications and games. 
Double-opening application has a small marker in the lower left corner to distinguish it from the original 
Mobile phone avatar
Mobile phone splitting is not a big news, and many of the products that are currently on the market are equipped with security. The MIUI 8 is also successfully used for reference. Of course, there is no difference in experience. After opening the mobile phone, it is equivalent to a visitor system in a mobile phone. Different fingerprints and passwords can be used to enter the corresponding system, effectively avoiding the need to “borrow your mobile phone. Use me with "".
After turning on the mobile phone, the data and applications in the two spaces are completely isolated from each other, so you can rest assured that you can put small butter big sister inside without worrying about being discovered.

Red rice Note4 uses 5.5 inches, resolution 1080p ips display, in view of thousands of machine positioning do not want to know also that the screen will not be too good. In terms of brightness performance, the color reproduction and the graininess of the screen are all within the standard. There is no place for too much color, and there is not too much phenomenon.
The red rice note4 in my hand is still using BOE's screen. The default color temperature is cooler than note3. Those who say that the screen is yellow may be Tianma screen?

Comparison of red rice note3 and red rice note4 life:
Life test I use the wp7 bar it is the main Yujian test method, see here for details
The test method is as follows: Wifi connection, indoor 50% off automatic brightness , 50% volume headphone output, continuously playing online with bilibili client full-bounce B station video av105250 (Clannad After Story 720P), full charge from mobile phone 100% The battery starts to play until the power is turned off automatically
The setting picture is as follows: The brightness of the mobile phone is 50%, the automatic brightness is turned off , the quality of the ambient room video quality is prioritized, the playback is set to automatically change P cycles, the decoding mode selection system is hard to solve, and the screen barrage is unlimited 
At the time of 13:57 , the test began. At this time, 99% of the red rice note3 power, 100% of the red rice note4 power 
At 15:19 , the red rice note3 power 85% , red rice note4 power 80%

Seven. The advantages and disadvantagesAdvantages 1. Compared with red rice note3, there is a significant increase in the appearance of the process color value, etc.
2.miui8 new application avatar, sweeping and other functions are very practical
3. Fingerprint support Alipay payment
4 support double click on the bright screen
Disadvantages 1. Battery life is much larger than the previous generation's note3 (MediaTek's pot)
2. Some serious fever
3. Does not support fast charge
4. MediaTek x20 is less than Xiaolong 650 in user experience. The difference is mainly due to the difficulty in playing games and the large amount of heat. Of course, the daily application is not that different, some applications start faster than note3
Red rice note3 and red rice note4 how to choose it?
In general, the main point of the red rice note4 upgrade is design, not performance. If users also play daily applications such as WeChat and do not play games, then I highly recommend red rice note4.
If you have high performance requirements and game requirements, red rice Note3 full Netcom more suitable for you, the price is also cheaper 100
