Before Nokia 8 was launched in China, Nokia 7 temporarily shouldered the burden of expanding the domestic market. The starting price of Xiaolong 630 and 2499 determines that it is a product easier to sell than its own big brother. In the eyes of most people, Nokia 7 and Nokia 8 are the official return of Nokia. But in the eyes of many players, this is just the belief of HMD to cheat money. Which side is right? Let's take a look at the real Nokia 7.
In terms of configuration, Snapdragon 630+5.2 inch IPS screen+1600W pixel sensor+F1.8 aperture Zeiss lens, 3000mAh battery, 4/6G memory+64G storage, and the price is 2499/2699 yuan respectively.
Packaging and appearance
Drawer type carton packaging, a bit thin, with one-time anti-counterfeiting seals.
Accessories include instruction manual, card pick-up pin, hard transparent case, Type-C data cable and quick charging head. The quick charging head is a whole circle larger than that of common mobile phones. It supports three output specifications of 5V/2.5A, 9V/2A, and 12V/1.5A, with a maximum output of 18W. It is manufactured by Salcom and its model is FC0304.
The front is square, and the 2.5D glass has a small radian. It has a familiar Nokia flavor. Although the chin is long, there is no touch button, which is a pity.
The 3D glass on the back is very textured, and the towering rear camera has bright radian edging. The overall appearance is very pleasing to the author. The camera is certified by ZEISS, and its CMOS is Samsung's S5K2P7SX. Its specification is the same as Sony IMX258, with 12 million pixels, 1.12 μ m unit pixels, and F1.8 aperture. It has no optical anti shake.
The top antenna slot is integrated with a 3.5mm headphone connector, and the bottom is a dual hole speaker, a Type C connector, and a main microphone. The metal middle frame is very thick, and the speaker and interface openings are very deep. This kind of leather texture is very "Nokia".
The left sim card slot, the right volume and power buttons, and the dual nano SIM card slot can be inserted with dual cards or nano SIM+TF cards.
Fingerprint and feel
The 5.2 inch "small screen" has a good border control. The metal middle frame with radian has a good grip. The back of the metal middle frame is slightly higher than that of the glass. Fingerprint identification requires about 10 times of pressing, and there is a very considerate prompt in the pressing area during the entry process. The recognition speed is not bad, but after the fingerprint is detected, the speed of entering the system is slightly slow, and the overall speed is in line. The fingerprint identification button is slightly low for male users, and the groove is shallow, so it needs some time to adapt.
Screen: classic IPS
The body information shows that Nokia 7's screen panel is from FIH (Foxconn), and it is a video screen (which consumes a little power). The touch screen chip is Yili. The audio decoding chip is integrated by the power management chip PM660L. From the original material selection, the internal cost control of Foxconn/HMD must be very strict.
Nokia 7 The 5.2 inch IPS screen is used, and the measured maximum brightness is 489 nits. The uniformity is satisfactory. Our testing machine has a certain degree of darkness in the upper half of the screen, but it does not affect daily use. It is always more pleasing than some JDI screens with their own twill effect. Nokia 7 has no screen mode to choose from, but has eye protection mode.
At a brightness close to 100 nits in daily use, the color temperature is 7294K, the contrast is 1302:1104, and the average deltaE of the color is 3.9, the maximum is 6.5 (as a contrast, the iPhone 7 is 1.6, the Note 5 is 1.8, the S6 edge+is 2.6, and the S7 edge is 2.9). It is a very mainstream IPS screen level for domestic computers, with no big selling points or slots.
System: original minor revision
Desktop and Settings
Advanced system functions
Nokia 7 is equipped with a nearly native system. The bottom layer is Android 7.1.1. In terms of functions, it only adds some domestic necessary functions such as self start management, and advanced functions such as body gesture and virtual key control. However, there is still a small problem with the smoothness of the current version. The application is slightly slow to open and switch. Even if the animation is closed, the response delay can be felt. Its biggest feature is that it is clean and the system is lightweight. The main problem is that the current version does not seem to have the speed advantage that lightweight will bring, and the response speed needs to be improved.
Performance: Snapdragon 630 has the advantage of GPU
Comparison model
Nokia 7 is equipped with Snapdragon 630, which provides 4/6G memory+64G storage. The Snapdragon 630 is a 14nm LPP process, the CPU part is an 8-core 2.2GHz A53 (the actual use is 4 * 2.2+4 * 1.84), the GPU is Adreno 508, equipped with 1333MHz LPDDR4 memory, and it is a low-end product.
CPU computing performance
Memory performance
GPU graphics performance
Flash memory read/write performance
The basic performance of the actual CPU performance is not much different from that of the Snapdragon 625/626, and may even be inferior to the tuned 625 model; GPU performance is the main improvement point. Compared with Xiaolong 625, it has also made great progress, crushing the competitive products of the seniors and MediaTek P23/P20 at the same price; In terms of storage performance, continuous read and write performance is OK, but it may be a system optimization problem. Random read and write performance is average.
In terms of core scheduling, Nokia 7 is very active. When the application is started and under heavy load, it can fully open 8 cores, and its thermal stability is outstanding. The room temperature is 26 ℃, and 10 minutes after the 8-core full open toaster, there will only be a very short time of small frequency reduction. The body is only between warm and hot, and the stability is impeccable. On the whole, Nokia 7 can be used daily, and its game performance has improved significantly compared with 625, so it will wait for the official system response to be optimized.

Photo taking interface
Two modes of taking pictures at the same time (the left mode is only 4.2 million pixels, and the right mode is only 2.4 million pixels, purely recording)
Camera section, Nokia 7 The main camera is Samsung's S5K2P7SX, which is very close to Sony's IMX298 in specification. This is also used for the rear of the vivo X9s, with 16 million pixels, 1.12 μ m per pixel, and F1.8 aperture, but no optical anti shake. 5 million pixels in front, 1.4 μ m+F2.0, 84 ° wide angle.
The camera app is also very close to native Android, but unfortunately Nokia's cool manual mode has disappeared. With automatic HDR and night view:
Focus: The focusing speed and success rate of Nokia 7 are relatively slow, close to those of the domestic flagship several years ago, and the weak light bellows still have a certain probability of false focus. But ordinary imaging speed is slow;
Film speed and film rate: The speed is obviously slow, and you have to refocus according to the shutter advantage. The film rate is OK in the machine without optical anti shake, but now that optical anti shake is running all over the street, the film rate is not very good;

Light metering/saturation: In the actual film, the Nokia 7 light metering tends to be dark, and the image brightness cannot be maintained under extremely weak light. Even if HDR is triggered, there is an obvious lack of tolerance, and the white balance is obviously red. The most special thing is that the contrast of the image can be improved, and the painting and sharpening efforts are very heavy. HDR and night scene multi frame synthesis will lead to a significant rise in color saturation, and the color of the proof is very pleasing to the eye.
White balance/discrimination: When placed with the iPhone 7 Plus, which is famous for its true restoration, 90% of people will think at first glance that there is something wrong with several iPhone proofs with elegant, true colors and high tolerance... In terms of discrimination, there is nothing like the Zeiss lens+1600W+gravity sharpening, which crushed the 12 million pixel iPhone without any doubt in the daytime, This advantage can be maintained to the normal dark light environment. When the light goes down, the Nokia outsole will kneel down without optical anti shake. However, strong smearing and sharpening lead to the loss of a large number of object textures and the hardening of the picture with a sense of optimization.
On the whole, the photos taken by Nokia 7 are far better than expected No shame for the names of martyrs like Chase and Lumia 1020 Has.
Endurance&Charging
Nokia 7 is equipped with 3000mAh battery. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, and 30 minutes of local video playback, after a total of 2 hours of endurance testing, the remaining battery power is 81%. The performance of the phone with only 3000mAh battery is very good.
Charging power
Charging curve
N okia 7 Support 5V/2.5A, 9V/2A, 12V/1.5 A Three output specifications, up to 18W. The actual maximum charging power is only about 15.2W, 5% - 100% charging, 10 minutes to 18%, 30 minutes to 44%, a total of 1 hour and 54 minutes. Conversion with battery capacity After that, the speed in the early stage of charging was smaller than that of Xiaomi MIX 2. After 50% of the power, the speed decreased, and after 90%, it entered the trickle. The limit speed was satisfactory, and the speed decreased too early, resulting in a moving overall duration.
summary
Even without the logo, Nokia 7 is also a good midrange computer. The sincerity of the producer can be seen from its solid, refined, sufficient performance, good endurance and unexpected eye pleasing photos. However, the price of 2499/2699 yuan makes it inevitable that Nokia 7 will be caught and compared with Xiaomi 6/Glory V9/nubia Z17/One Plus 5, or even Meizu PRO 6 Plus.
Yes, Nokia 7 is vulnerable to attack in front of these flagship ships, which is the reason why the author mentioned "faith" many times. Today's Nokia 7 needs more faith than the previous hammer. however, Even though many people have doubts about HMD and Nokia's pedigree, this is the Nokia we can buy in 2017.
