With HMD taking over the Nokia brand, the legendary mobile phone brand that once dominated the world has returned to people's vision. For the post-80s and post-90s generation, this is a brand that is very familiar. In everyone's green years, there is a little Nokia. Now under the helm of HMD, Nokia has the potential to become a latecomer. It has successively launched a number of Android and retro models, and the market response is also higher than expected. Recently HMD launched another new product - Nokia X7, Snapdragon 710, 6.18 inch TFT Liuhaiping, which still focuses on cost performance. However, unlike in the past, this X7 is equipped with IMX363+Zeiss certified lens+optical anti shake, which can be called the horn of Nokia's counter attack in the field of photography.
Unpacking and appearance
The packaging box is still the usual style of HMD, bright color+Nokia logo+symbolic handshake logo, familiar Nokia style.
The overall design style is mellow, but it still has a strong Nokia style and is still familiar. The first thing that came into view was the 6.18 inch TFT Liu Haiping with a resolution of 2246 × 1080, officially named Nokia PureDisplay.
This screen belongs to the wide type of bangs. However, in the era when bangs and water drop screens are all over the world, it seems that there is not much disharmony in bangs. Habit becomes natural.
The arrangement of various components in the fringe is relatively scattered, but since there is no 3D structured light, it will be more pleasing to compress the space of the fringe as much as possible.
The logo of Nokia is printed on the chin, which is also a reserved item for many Nokia models. After all, it is Nokia, and many post-80s and post-90s people still have feelings to add.
The black edge of the screen edge is not narrow, which is probably determined by the characteristics of the LCD material itself. Today, when the border is getting narrower and narrower, OLED's bendable feature is indeed more advantageous on the way to full screen, but it is still uncertain whether stroboscopic is good or bad.
If the round front still makes you hesitate, then the back design is a thorough Nokia style. Since the return of Nokia, its simple and clear back design has run through the entire product line, simple.
The Nokia X7 is equipped with a dual camera of 12 million pixels+13 million pixels. The main camera sensor is IMX363, equipped with Zeiss lens, and has optical anti shake support. This is also the strongest camera hardware model launched by HMD after taking over the Nokia brand.
The key layout of the fuselage is relatively conventional, and the top noise reduction microphone+3.5mm headphone jack; Bottom speaker, call microphone, USB Type-C interface; The left side of the fuselage is the SIM card slot; On the right side of the fuselage are the volume button and the power button from top to bottom.
In terms of configuration, the machine adopts Qualcomm Snapdragon 710, which provides 4G+64G/6G+64G and 6G+128G storage versions, with prices of 1699 yuan, 1999 yuan and 2499 yuan respectively. In other configurations, 3400mAh battery is built in, 20 megapixel camera is in front, fingerprint recognition is in the rear, and Android 8.1 is pre installed in the factory.
Screen quality
In terms of screen, Nokia X7 uses a 6.18 inch TFT bangs screen with a resolution of 2246 × 1080, officially named Nokia PureDisplay, which is a relatively wide bangs screen. The touch chip is from Taiwan Qijing Radio and Television, and the screen supplier is Shenzhen Super.
In terms of official parameters, its maximum brightness is 500 nits, supports HDR effect, supports DCI-P3 wide color gamut, and the screen color gamut actually covers 96% of NTSC. In this era when OLED screens dominate smart phones, excellent LCD screens are hard to find. It's not easy to think of "blindness".
In terms of objective data, in the default mode, the color temperature is about 7600k, slightly cold, the contrast is 1500:1, and the maximum brightness is about 520 nits (even higher than the official promotion). In sRGB mode, the sRGB gamut coverage is 100% (the part exceeding 100% will not be displayed); In terms of color standard, the average DeltaE is 4.2, and the highest DeltaE is 7.8.
In DCI-P3 mode, P3 gamut coverage is 93%; In terms of color standard, the average DeltaE is 3.3, and the highest DeltaE is 7.9. The objective results of the test are relatively general, especially in terms of color accuracy, which is just in line with the rules, but considering the pricing, it seems that it is not a problem. In fact, the appearance is pretty good. The brightness and fineness are enough. Compared with those 1080P OLED screens, it's really fragrant.
Running score and performance
In terms of configuration, the machine adopts Qualcomm Snapdragon 710, which is matched with three storage versions: 4G+64G/6G+64G and 6G+128G. The memory uses Samsung's LPDDR4X, and the built-in storage is eMMC.

Memory performance
Storage read/write performance
In terms of performance, the processor, graphics and memory scores of the same class models using Snapdragon 710 are all in the middle and upper reaches. There is no need to worry about the performance. For most users, daily use is enough. The score of built-in storage is relatively less prominent, especially random writing, which is slow.
Photographing experience and imaging effect
The Nokia X7 is equipped with a 12 megapixel+13 megapixel dual camera. The main camera sensor is IMX363. It is equipped with a Zeiss lens and has optical anti shake support. The subphoto of 13 million pixels is S5K3L6. After our actual test, it is only used as the depth of field camera and does not participate in daily photographing. After occlusion, it does not affect the actual focus and view taking.

The performance of the same sensor in the daytime is really similar, but there is still a slight difference between the three. Xiaomi 8 is the best in terms of overall performance. It is well balanced in all aspects, with the brightest color and the best appearance, but the sharpening performance is not very good. The nut Pro 2S is moderate and has no features, but it also has no major shortcomings. Nokia is more distinctive, with the strongest discrimination among the three. Sharpening is also very important. The disadvantage is that the exposure is slightly insufficient, the color is slightly dim, and the tolerance can only be said to be general.

If the same sensor can not open the gap in the daytime, the night is the real test. The X7 is amazing at night. The first is the use experience. The availability of automatic HDR is very high, which is the best of the three. It feels like using Samsung, and there is almost no waiting time. The second is the optical anti shake. The film rate is really high, and it can be used in casual shooting.
In terms of picture quality, the overall brightness of the picture is relatively low, somewhat dark; But the ultimate discrimination is the best among the three, with the most details retained, but the edge image quality is slightly worse; Sharpening is good, and we can see that we have worked hard on the algorithm. There are two main disadvantages. First, the purity of the image still needs to be improved. The noise control is general, but the painting is still uniform; Second, the saturation of the screen is general, especially the scene with low brightness. The overall color is gray and not as good as the other two models. To sum up, the author believes that the Nokia X7 is weaker than the Xiaomi 8, but still slightly ahead of the Nut Pro 2S.
Endurance and charging
In terms of battery, the Nokia X7 has a 3500mAh lithium battery built in, which is a normal capacity in the same size model, and the endurance performance is not unexpected. It is at the same level as other models that use the same SoC.
In terms of charging, the built-in charger is an ordinary 9V2A, and the maximum power of the fast charging head is about 17W when the battery is low. QC fast charging is normal.
System and experience
In terms of system, Nokia X7 continues the style of native Android, and the system is very clean. Although it has made some localized adaptation for mainland China, there are not too many built-in applications. Users who like native style should prefer it.
Application permission management, bootstrap management, etc. are still necessary. After all, the Android application environment in mainland China is relatively harsh. Without these Android applications, it is basically impossible to move. On the whole, the system still needs to be praised. However, although the system is lightweight, it still feels slightly stuck occasionally, or slightly unsmooth. There is still room for optimization and progress. After all, the biggest advantage of lightweight system is smoothness. (Just a few minutes before the deadline, the author suddenly noticed the shaking hand feeling. Well, it can only be said that the hand feeling is very expensive, you know
summary
As a powerful work of HMD in the field of mobile phone photography after taking over the Nokia brand, the Nokia X7 can be said to have earned a lot of momentum. Although its positioning determines that it is only a mid-range machine, it is undoubtedly the strongest model since Nokia's return in terms of photography. It is commendable both in terms of photography experience and the final imaging effect of photos.
First of all, in terms of photographing experience, HDR shooting is almost at the same level as Samsung, and there is basically no waiting time. We all know that it is background HDR processing, but it is still commendable. It is higher than those models that have been circling for several seconds.
As for the image quality, there is still a gap between it and Xiaomi 8 with DXO Mark 105 points. But with the blessing of optical anti shake, players like Nut Pro 2S are not inferior at all. Although the resolution is obtained by giving up saturation, the author believes that its imaging effect is slightly better than Nut Pro 2S. If I had to choose one from the other, I would choose Nokia.
After completing the short board of photographing, the biggest problem of Nokia X7 at present is probably that there is still some lack of system optimization. It does not mean that the lightweight system is not good, but there is still room for improvement in smoothness. Compared with other Snapdragon 710 models, Nokia X7 always has a sense of inexplicable lag. If further optimization can be made, I believe that the future is foreseeable.
