2K screen+super camera function Nubian Z7 experience evaluation

IT 168 evaluation Nubia launched a new series of Z7 products in July this year, including three mobile phones: Z7, Z7 Max and Z7 mini. The latter two have already been fully sold and achieved good sales. But in fact, the real flagship Z7 has not appeared for a long time. After four months of debugging, Nubia recently officially put this mobile phone on the market. Although it is a little late, the comprehensive strength of Nubian Z7 still belongs to the current high standard flagship level, and 2K screen, professional camera and 4G full netcom have also become the main features of this product.

From the price point of view, the Z7 mini with a price of only 1499 yuan in Nubian Z7 series has the most price advantage. In fact, during the release period, this Z7 mini did achieve quite good sales. It can be seen that cost performance has become the most sought after part of users, and the most important factor to highlight cost performance is naturally the most sensitive price part of users, which is also the part to be discussed in this paper. Nubian Z7 with 3456 yuan can be said to be not cheap, so where is its product highlight? Can users buy it?

Before that, let's review the main features of Nubian mobile phones. Z7 focuses on metal technology and 2K screen display, positioning high-end flagship, priced at 3456 yuan. The Z7 Max and Z7 mini are mainly positioned in the civilian market. Both of them use 1080p screen,10 million pixels, and are equipped with Qualcomm Snapdragon 80 1 processor. Generally, the fuselage size is different, and there is little difference in other aspects. The prices are 1999 yuan and 1499 yuan respectively.

▲ Comparison of hardware parameters of three products

It can be seen intuitively from the comparison chart that the three products of Nubian Z7 series are still quite different. The flagship Z7 has a 2K screen, 3GB RAM and a13 megapixel camera equipped with optical image stabilization, but the difference between Z7 Max and Z7 mini is not big, mainly due to the screen and processor. The processor of Z7 mini is a low-end processor in Snapdragon 80 1 series. However, it should be noted that MSM8974AA, even if it is a low-profile benchmark, still has certain advantages compared with other processors, but it is a little introductory in the positioning of the same series.

If only the hardware leads, I believe that the price of Nubian Z7 as high as 3456 yuan can't convince the public. Therefore, Nubian Z7 does have many bright spots in design. The biggest feature is the addition of metal frame elements, and the overall design sense has been strengthened. Therefore, when using the mobile phone, you can clearly feel that the Nubian Z7 has obviously improved its workmanship and feel compared with the other two mobile phones in the Z7 series, which really conforms to the positioning of the flagship. In my personal opinion, this level of workmanship has already killed the domestic popularity of Wang Xiaomi 4 and lost to Meizu MX4. It can be said that it is the most exquisite product in Nubian Z series.

▲ A mobile phone product with 2 K screen and ultra-high screen ratio.

The front of the fuselage adopts a 5.5-inch Sharp screen with a resolution of 2560x 1440 pixels and a pixel per inch of 534ppi, which is the high standard screen standard in flagship machine at present. In addition to the high-resolution screen, Nubian Z7 has also achieved a narrow bezel design of 3.6 1mm on the screen, accounting for about 72% of the screen, and the visual effect is still good.

The front details are the same as other mobile phones, and there are common photosensitive elements. It is worth mentioning that Nubian Z7 has also made a meditation design on this handset, and the ellipse is distributed in a single-row lattice. Compared with the engineering machine we saw when it was released in July, it has a brand-new change. The main advantages are that it can increase the volume of the receiver, with better dustproof effect and stronger aesthetics. In addition, the front camera is also as high as 5 million pixels, and includes glamorous shooting, which can meet the needs of users who like selfies.

▲ Top-level design gives consideration to design and beauty.

The bottom of the fuselage is still a small red circle, after several generations of product development. This design has become the iconic feature of Nubian products. In addition to one-button return, it also has a reminder function. There are also a return button and a menu button on both sides of breathing light, and their positions can be adjusted with each other, which is also a part of Nubian humanized system.

▲ Red breathing light is a characteristic of Nubia.

The frame part is the highlight of Nubian Z7. Officially, the integrated metal frame structure is made by 15 process, which can keep the firmness and reduce the weight at the same time. From the perspective of the body thickness of 8.9mm and the weight of 170g g, it is consistent. In addition, you can actually see the matte coating process on the surface of the metal frame, which feels really good.

▲ The fuselage is slimmer.

▲ The metal buttons on the side are handled delicately.

In addition, careful users can observe that there is actually a certain height difference between the border and the screen. This is mainly due to the impact coefficient when the fuselage falls. The height difference can buffer the external force on the screen and reduce the screen breakage rate. Of course, even if Nubia has made such protection, we suggest that we should be more careful when using it. If you fall face down, the probability of broken screen is still large.

▲ The two-level camera buttons on the side and the front echo well.

▲ Mic handset and USB interface at the bottom.

It is worth mentioning that Nubian Z7 has also spent a lot of thoughts on the physical buttons of the frame. The buttons of the fuselage have introduced a metal matte process, which makes people feel very good in feedback and feel. In addition, in the physical photo button part, in order to match the red breathing light design of the main screen, the red dot logo was added, which also brought us unexpected surprises.

Generally speaking, the appearance of Nubian Z7 gave us a great surprise, which is also in line with its flagship positioning. In the current environment where consumers pay more and more attention to design, Nubian Z7 has its good advantages. The process of metal integrated molding is worthy of recognition, and the comfortable grip also adds a lot to it. Judging only from the appearance, it really meets the pricing of 3456 yuan.

Nubian Z7 is also the mainstream solution in the current industry in terms of core processors. 2.5GHz Qualcomm Snapdragon 80 1 chip (MSM8974AC) integrates Adreno 330 graphics card and is equipped with 3GB of running memory. Needless to mention the dual-channel DDR3 attribute on the hardware. At present, too many flagships adopt this configuration.

▲2K screens also have higher requirements for hardware.

But the question we need to pay attention to is, Nubian Z7 uses a 2K screen, so how does Qualcomm Snapdragon 80 1 optimize the 2K screen?

In this regard, we might as well take a look first. At present, there are only four chips capable of carrying 2K screens in the industry, namely Qualcomm Snapdragon 80 1, Samsung Exynos 5433/5430, MediaTek MT6595T and Huawei Hisilicon 928, among which the first two chips have been commercially produced, such as Nubian Z7, LG G3 and IUNI U3 using Qualcomm Snapdragon 80 1. Only Samsung Note4 and Meizu MX4 Pro use Samsung Exynos 5433/5430. As for MediaTek MT6595T and Hisilicon 928, they have not been commercialized at present, mainly because of the balance between power consumption and performance.

▲ Overview of basic hardware parameters and general fractions.

Therefore, Nubian Z7 using Qualcomm 80 1 is also a common solution in the industry at present, and we don't have too many exceptions. However, the combination of 2K+ Qualcomm 80 1 is common, but we still need to make a rough calculation by running scores.

▲ Ann Bunny detailed running results

The tests include the most common Ann Bunny running score, GFXBench test and 3D mark comprehensive test.

▲ A number of professional running tests

From the analysis of the above results, the operation effect of the machine is at the current mainstream high-end level. Although the overall hardware level of Adreno 330 graphics chip is not the highest, it has not been delayed because of the use of 2K screen. Many graphics tests can run at 60 full frame rate, so the game controller can buy and use with confidence.

Since Nubian Z5, it has been focusing on multi-function camera technology. Until the launch of Z7 series this year, there was a "shooting stars" craze on the Internet, which showed the perfection of mobile phone functions. Of course, the photo function is different from the proof effect, so it is necessary for us to look at the proof in the face of Nubian Z7.

▲ 1300W pixel main camera

Let's take a look first.

In terms of hardware, nubia Z7 is equipped with a 500w pixel front camera, which supports 88-degree wide-angle shooting. The main camera is 1300w pixel, using Sony's second-generation stacked CMOS sensor, f/2.0 large aperture, OIS optical image stabilization function, and equipped with dual color temperature LED fill light; In addition to hardware, the machine also supports brand new.

The camera function of NeoVision 4.0 has been upgraded again in the original Auto, Pro and fun modes.

▲ Fun mode shooting generally requires tripod, a device that stabilizes the fuselage for a long time.

Speaking of the three modes, there are three levels of mobile phone photography; For example,

Automatic (automatic)

Next, you can complete the ordinary fool license;

Fun can be used to take interesting photos such as light track/light painting/double exposure/star track/nebula, and the application basically has default settings, so you can complete interesting and simple shooting according to the tutorial; In Pro mode, you can adjust the parameters including focal length, exposure duration, aperture size, etc., and really control the lens to shoot the desired effect.

▲ After manual focusing, the macro can be closer and the accuracy is higher.

So, apart from the function, what is the sample effect of this product? Let's take a look at the proofs.

It should be noted that the sample we evaluated this time only chose the automatic photo mode, which is also the most commonly used mode for everyone to take photos. Judging from the proofs, the performance of the machine in white balance is still very good, neither too warm nor too cold. From many real shots, the stability of white balance is also very high. At the same time, due to the separation function of metering and focusing, the light and dark tones of the picture can actually be adjusted before taking pictures, so it has inherent advantages in color and sensitivity.

▲ Outdoor weak light proofs

▲ Night proof display

In the aspect of night proofs, Z7 benefits from optical anti-shake technology, and the overall picture brightness is good; At the same time, the glare suppression effect of the overall picture is not bad. However, it is a pity that from the current photos, the edge painting value of the night scene effect can be seen with the naked eye to a certain extent, which is also a common problem of optical image stabilization at present.

Nubian Z7 is equipped with a brand-new nubia 2.0 UI, with a flat interface and many functional adjustments. On the whole, the system adds a lot of springback effects similar to "rubber bands". On the basis of flat UI, a large number of streamlined design languages are used, and with the display screen with ultra-high screen ratio, the visual effect is excellent, which is also the "consistent user experience" maintained by Nubian's whole series (the system experience is similar).

Of course, if a system has only an interface and no function, it is missing. So the next part is the function description. The first is the screen lock interface. This time, Nubia changed the previous iconic circular unlocking and chose a more convenient upward unlocking mode.

At the same time, rowing to a certain height can directly activate the camera interface.

Officially enter the main screen, you can see the adjustment of nubia 2.0 UI on the icon. Although they are all flat, Nubian has treated the icons with "highlights, shadows and projections". Functionally, Nubia has mainly improved the interactive experience, the most famous of which is the "bottom button customization function"

Yes In this interface, you can adjust the position of menu key and back key, which is very practical for this super-large screen mobile phone.

As a 5.5-inch screen product, Nubia also has a built-in split screen function.

In addition to opening two operation interfaces at the same time, you can also adjust the ratio between screens at will. However, the actual experience shows that it is still a bit cramped to split the screen in the size of 5.5. In addition, for "screen control",

In addition to the original saturation adjustment, nubia 2.0 UI also adds hue adjustment.

. Whether you like "thermos bottle" or "cold bottle", don't worry too much.

Of course, a good sense of operation often depends on the combination of "hardware+software". This time, Nubian Z7 comes with the latest Nubian UI2.0. In fact, it has made some adjustments in one-handed operation, the most typical of which is the "one-handed mode". In this mode, the screen will automatically shrink to a floating display area of about 4 inches. In addition, the new double-click screen wake-up also greatly reduces the probability of palm movement during operation. But also, the 5.5-inch screen reduces the operation of the top touch area and moves the top operation down, which is much more practical than this simple shrinking display.

To sum up, the latest nubia 2.0 UI not only retains the classic applications such as cowboy electrician (power housekeeper) and nubia shield (program management) in the original UI, but also puts a lot of effort into the UI interface and interactive functions, and the overall performance is excellent. However, it should be noted that due to too many animations, although it runs smoothly, there is always a feeling of procrastination in switching. You can adjust the animation speed in the settings.

So far, the routine evaluation of Nubian Z7 has basically come to an end, but we still need to briefly talk about the performance of 2K screen and the specific network support effect of dual-card 4G. After all, Nubian's performance is not much different from mainstream mid-to high-end products. The only thing that can differentiate them is these special functions.

▲ Dual card dual 4G has always been Nubian's main function.

Let's talk about the problem of 4G dual card dual standby. After all, from X6 to Z7, Nubian series has been promoting dual-card 4G function. At the same time, according to official website's description, Z7 supports "TDD-LTE/FDD-LTE/3G full netcom, and two card slots support soft handover of 4G/3G networks". However, experience tells us that it is almost impossible for dual cards to keep 4G online at the same time, so how the so-called dual 4G is embodied needs to be tested.

To explain dual-card 4G, we must first explain it from two angles. On the one hand, it is G network +G network (mobile+Unicom 4G mixed insertion), on the other hand, it is C network +G network (telecom 3G+ mobile/Unicom 4G). Telecom 3G is chosen instead of 4G because the promotion of 4G in Beijing is a little slow.

▲ There are still clear restrictions on the main and secondary cards under the telecommunications network.

In the actual measurement, after inserting the 4G cards of China Mobile and China Unicom at the same time, we found that the mobile phone can switch between the two cards as the main card at will, and allocate the main card to use the 4G network and the auxiliary card to use the GSM network. Although it is true that dual-card 4G can be switched at will, it basically adopts the previous 4G+GSM principle; In the case of 3G+ Mobile/Unicom 4G, we found that only the main card (SIM card slot 1) can find 3G signals after inserting the telecom card, but the auxiliary card does not support 3G/4G. At the same time, if the secondary card is inserted into Unicom/Mobile 4G card, it can't switch to 4G or 3G frequency band normally, that is to say, the primary and secondary cards can't switch between 3 and 4G networks.

▲ Nubian, the telecommunications network, is also explained in detail in the system.

When using Nubian Z7 Max, telecom users can only set up the telecom card as the main card, the network part can only be realized by CDMA, and the auxiliary card part only has GSM network, regardless of whether the auxiliary card is 3G/4G or not. Of course, considering that telecom users will get the 4G signal of FDD-LTE, in fact, in the telecom mode, Nubian Z7 Max has the dual card dual standby single pass mode of CDMA/FDD-LTE (telecom) +GSM.

The last part is the 2K screen. Although the basic hardware level of 2K screen has been stuck in a considerable horizontal line, it is of little significance to study the screen display effect excessively. However, for users, it is still necessary to talk about the characteristics of the current 2K screen mobile phone and which one is more worth buying. So before it's too late, let's look at a watch first.

After reading the above table, it is not difficult to find that the overall hardware level is similar in a 2K-screen mobile phone, and there is not much difference between the two only from the conventional content. Among them, Meizu has fingerprint recognition, IUNI has a water drop screen and the price is not high, LG G3 has infrared night scene focusing and ultra-high screen ratio, and Note has a handwriting function that has always been tall. Faced with these, the selling point of Nubian Z7 is dual 4G, and the price is not low. Comparatively speaking, it is not an irreplaceable product at this price.

Evaluation summary: Netcom has always been Nubian's main function. Starting from Nubian Z7 series, single card became dual card, the screen was upgraded to 2K, and the UI was completely flat. It should be said that it has been fully upgraded. Judging from the evaluation content, Nubia has performed well in all aspects and has no dead ends. It should be said that the vertical improvement of Nubian Z7 is still great.

▲ A mobile phone with great vertical improvement.

Horizontally, as a high-end product, Nubia's 2K screen comparison in this functional section is also clear from the table. It should be said that Nubian Z7 is not the only irreplaceable product at this price. Therefore, the effect of "the best choice at the same price" cannot be achieved. However, there is specialization in the industry, and Nubian's advantages in network are really irreplaceable by other products, so users who have dual cards and tell the network needs will not regret choosing Nubian Z7 in the experience.

▲ Network standard is Nubian's advantage.

In addition, only from the purchase suggestion, Nubia
