With the full distribution of Qualcomm's 10nm Snapdragon 835 processor, Android models have finally got rid of the image of poor performance caused by Snapdragon 810 and Snapdragon 820. A variety of Android models with strong performance have sprung up, including not only international manufacturers, but also domestic brands, of which Nubia is one.
After the development of many generations of mobile phones, Nubia has formed a considerable technological accumulation, and its symbolic red circle has also been deeply rooted in the hearts of the people. Today's protagonist, Z17, is their new masterpiece.
Unpacking and appearance
In terms of appearance, the Z17 continues Nubia's consistent design style. The front design is very simple. There is no logo on the forehead and chin. It only uses the symbolic appearance to show its identity - frameless design+red circle Home key. This time Nubia has made frameless extremely, so the front face is very powerful and has a high face value.
Because the symbolic red circle entity touch Home button is still used, it is expected that Z17 will not be able to identify the front fingerprint. The design of rear fingerprint recognition is relatively standard, located in the middle and upper part of the fuselage, and the color matching is consistent with the fuselage color.
The design style of the back is more Nubian, and the Nubian logo is printed in the middle of the fuselage. However, such a landmark design can quickly show your identity even without a logo.
In addition to the impressive frameless screen, the biggest highlight of the Z17 is the 23 million+12 million pixel rear dual camera, which continues Nubia's usual "red circle" appearance. Nubia has made remarkable progress in photography in the past two years, so we are looking forward to its flagship products.
Nubia has been promoting frameless design for many years, but previous products are more or less less extreme than the Z17. The almost frameless design of the Z17 at the beginning gives us a strong sense of impact. Nubia can finally call itself a true frameless design this time.
In terms of details, let's start from the front of the fuselage. There are only earphones, front cameras and LED indicators on the forehead. There are sensors hidden under the LED indicators.
The chin of the fuselage only retains Nubia's signature red circle Home button. The return button and multi task button are hidden on both sides of the Home button, which can be interchanged, and the backlight can be turned off, so the integrity of the panel is better.
In terms of back details, the Z17 is also simple. The rear dual core, dual color fill light, rear fingerprint identification and brand logo have nothing else. There is an antenna partition strip at the bottom, and the other antenna partition strip is located on the top frame.
The rear dual camera uses the red appearance that Nubia has always used, which has also become one of Nubia's iconic designs. The dual camera protrudes slightly from the body, but it is not obvious. The thickness is better than that of the iPhone 7 Plus.
The back of the fuselage is made of metal, but different treatment processes are used for different colors. The sand blasting process is used for red and black, and the polishing+coating process is used for blue. At first, it looks very close to glass, almost fake, full of texture.
Under the solid color wallpaper, we can more appreciate the charm of borderless. Although the screen proportion is not very high at present, the visual impact is still very strong. Even full screen mobile phones have never been so amazing.
The screen glass adopts 2.5D glass protruding from the surface. In the case of almost no frame, there is an illusion that the screen is suspended in the fuselage.
In terms of the side layout, there is only a SIM card slot on the left, which supports dual card dual standby, but not TF card expansion.
The buttons are all located on the right side. The upper part is the volume button, and the lower part is the power button. In actual use, the lower power button is more convenient for finger recognition and operation.
In terms of interface, Z17 uses the most common USB Type-C interface, which can be used with most mobile phone data cables. The loudspeaker opening is designed symmetrically, but one side is for decoration, and the call microphone is hidden inside.
In addition to the conventional noise reduction microphone and infrared sensor, the top of the fuselage also has Nubia's unique antenna partition bar design. Different from the general dome design, the Z17 injection molded partition bar is located in the center of the top frame from the edge up. Since the color of the injection molding is quite close to the fuselage, the hiding effect is very good.
On the whole, the appearance design of Z17 is very successful, which not only improves the aesthetic perception, but also well retains the consistent design style of Nubia. It can be said that both beauty and tradition can be achieved.

Performance and system experience
In terms of configuration, Nubia Z17 uses Snapdragon 835 processor, 6GB/8GB LPDDR4X for running memory, and 64GB/128GB UFS 2.1 for built-in storage, all of which are the top configurations in the current Android camp.
Moreover, this Snapdragon 835 is not the other Snapdragon 835. The Nubian Z17 is equipped with a full blood version of 835 with the main frequency of 2.45GHz, and the GPU frequency has reached 710MHz.
In terms of score test, its processor score is commendable. The single core score ranks first among all models that use Snapdragon 835 processor, and it is currently the model with the strongest single core performance of all models that use Snapdragon 835 processor. However, due to Nubia's relatively conservative multi-core adjustment strategy, Nubia is slightly inferior to the one plus five and Xiaomi six who also use Snapdragon 835 in multi-core run points, but also in the first echelon.
In terms of graphics performance, Z11 is the king. Nubia Z11 ranks among the top in the test of multiple scenarios of GFX. Except Xiaomi 6, which can compete with it in graphics performance, other models that use Snapdragon 835 processors are largely abandoned, including one plus five that also use the full frequency version of Snapdragon 835.
In terms of storage, read and write performance, the 64GB version we got has some disadvantages compared with the 128GB model. However, the Z17 still bucked the trend and has a quite amazing performance in continuous read, reaching 799MB/s, even slightly outperforming the top version of the Samsung Galaxy S8+. In terms of continuous writing, although it is not as amazing as reading, it also reaches the medium high level of using UFS2.1 chips. For random reading,
In terms of system, the machine is equipped with Nubia's latest Nubia UI 5.0 operating system, which is developed based on Android 7.1.1, and continues Nubia's consistent UI style. The overall style is relatively simple. Although the icon is not very distinctive, it is compatible with most wallpapers, which is quite golden.
In terms of operation logic, the nubia UI is similar to most Android phones, but it separates the notification center from the control center, uses the upward stroke method to activate, and integrates some common applications and shortcut functions.
In addition, the machine is also equipped with a number of very distinctive edge gesture functions, such as edge drawing to activate FIT Card, sliding up and down to switch applications, bilateral sliding to adjust brightness, etc. Although there is a certain learning cost, it is still more practical after use, especially sliding up and down.
screen
In terms of screen, the Nubia Z17 adopts a 5.5 inch screen with a resolution of 1080P. It adopts a new generation of frameless design, which is more extreme than the previous two generations. The screen really achieves the same width as the frame, and the appearance is still quite amazing. Although it is not a full screen design, the impact is not reduced at all.
In terms of objective data, in the standard sRGB display mode, the color temperature is about 7600k, which is relatively cold. The average DeltaE is 4.6, and the maximum DeltaE is 7.8. In terms of the maximum brightness, it is about 460 nits, which is fairly good on the IPS screen. In terms of color gamut, its sRGB color gamut exceeds 100%. As shown in the figure, sRGB has been completely covered, while Adobe RGB color gamut is 90%. It performs well in terms of color gamut.
It is worth mentioning that the contrast is not different in the maximum brightness and 100 nit brightness. This performance also shows that the quality of the screen is excellent, while the contrast of the screen with poor quality will be greatly different under different brightness.
In the color mode, its sRGB gamut and Adobe RGB gamut are at the same level as the basic mode, but the color accuracy has slightly improved. DeltaE has increased from 4.6 to about 3.5, and the highest DeltaE remains at about 7.9.
photograph
In terms of photographing, Nubia Z17 adopts dual rear cameras. The two cameras are 12 million pixels and 23 million pixels respectively. The former uses the IMX362 sensor from Sony, with a unit pixel area of 1.4 μ m and an aperture of f/1.8. The latter uses a lens with a double focal length and an aperture of f/2.0.
The front camera configuration is also excellent, with 16 million pixels, five lens and aperture of f/2.0. Next, let's take a look at Nubia, which has made great achievements in photography in the past two years, and what surprises it has brought us on Z17.

100% magnification
First, compare the conventional focus with the double focus. The conventional focus sample uses 100% magnification, while the double focus sample uses 50% magnification, and then compare. In terms of details, it is obvious that the double focal length has the natural advantage of the focal length, and has stronger details in many scenes. For some shooting tasks that are difficult to complete in the conventional focal length, they can be easily solved in front of the double focal length. In terms of white balance, the performance of conventional focus and double focus in multiple scenes is almost identical. There are some differences in the exposure. The samples shot with double focal length are generally higher than the normal focal length, but both are within the normal range. On the whole, the performance of Nubia Z17 in the daytime is quite excellent. The conventional focus section is comparable to the products of the same level, and the double focus section is also very practical. However, it is difficult to open the gap in the daytime samples of the models of the same level of sensors.
Portrait mode

Nubia Z17, as a dual camera phone, the portrait mode is also indispensable. Right stroke in the camera to enter the portrait mode. In the portrait mode, the main shooting object needs to stand within the area of 2 meters and use the algorithm to virtualize the background. In the actual test, the Z17's portrait mode performs fairly well. Although the edge blurring is not perfect in the backlight environment, it performs quite well in the normal light conditions. It can be said that it has achieved "the virtual reality, the real reality", and is still highly practical.
Indoor light and night proof

100% magnification
In terms of indoor light, both double focal length and conventional focal length show good quality, but there are certain differences in exposure and white balance between the two. The samples with conventional focal length are warmer and the exposure is relatively lower. Of course, in terms of magnified details, the double focus section has better performance in vein and petal texture thanks to the advantages of the focus section.
In terms of night proofs, the double focal length also has certain advantages in details compared with the conventional focal length. For the resolution of words in the distance, the double focal length lens is of great practical significance. Many conventional focal lengths are difficult to shoot. For the double focal length, the advantages of the focal length can be easily resolved. However, the Z17 double focus lens is slightly unstable in terms of white balance and exposure. Compared with photos taken with conventional focus, it is slightly lacking in picture purity and stability. But on the whole, the performance at night is also excellent. The conventional focus segment is more brilliant than the double focus segment lens. It is more recommended to use the conventional focus segment for shooting at night and in dark scenes.
Endurance&fast charging&heating
In terms of batteries, the machine is equipped with a 3200mAh lithium ion battery, which is basically at the same level in the same size models. However, in our three hour high intensity test, the Z17 still has good results. We have continued the test projects we have always used, including half an hour of game testing, half an hour of video playing, half an hour of WiFi surfing, half an hour of 4G surfing and one hour of music playing.
After three hours of high-intensity endurance test, its remaining power is still 79%, which is still outstanding in the same class of aircraft. After experiencing the dormancy of Snapdragon 810 and 820/821, Qualcomm finally launched the Snapdragon 835, which performs well in performance and power consumption. Many models using Qualcomm chips also benefit from this, and Nubia Z17 is one of them.
In terms of charging, Nubia uses Qualcomm's latest QC4+fast charging, but the original charger is not a QC4+charger. In the case of low power, the charging power of the original charger can reach about 15W, reaching the normal level.
In terms of charging curve, the first 90% or so has a relatively fast charging speed. 0-90% only takes about one hour, which is relatively fast for emergency charging. After about 90%, it enters trickle charging, and the speed slows down. It takes about half an hour from 90% to full charge. The whole charging time from 0 to 100% is 98 minutes.
In terms of heating, after about half an hour of NBA 2K game testing, the maximum temperature of its front is 37.5 ℃, and the maximum temperature of its back is 38.5 ℃. It is relatively reasonable to control the temperature. The main heating parts are basically located in the middle and upper parts of the fuselage, avoiding the most commonly held parts in daily life.
summary
As the annual flagship of Nubia, the Z17 has a very powerful configuration. It is equipped with a full blooded Qualcomm Snapdragon 835 processor+6GB/8GB of operating memory. It is one of the most powerful smartphones at present. Among many models that use Snapdragon 835 processors, not many use full blood and full frequency. Nubia Z17 is one of them, and its graphics performance score is even better than the Snapdragon 835 model.
In addition to its very strong performance, the appearance is also a highlight of the Z17, which continues Nubia's consistent frameless design style. This time, the Z17 has achieved extreme excellence. There is almost no black edge between the screen edge and the frame. Nubia can be proud to call itself a "frameless" design.
However, compared with the stunning front panel, the design of the back of the fuselage is somewhat conservative, but different colors have different back treatment processes, which is still impressive. The overall performance of the first echelon is not good enough, but it is still a stunning appearance. In addition to good cost performance, the Z17 can not only be called the best model in Nubia's history, but also the flagship of Android in active service.
