The Yijia mobile phone with the slogan of "no compromise" was officially launched. Its powerful hardware configuration was presented at a price of less than 2000 yuan. The main selling point of the Yijia mobile phone was its so-called best feel. After a period of experience, is the Yijia mobile phone an angel like cost-effective magic device or a devil like camouflage product?

The packaging design and accessories of Yijia mobile phone can be said to be the most special and thoughtful I have ever seen. The external charger and the body packaging of Yijia mobile phone make the mobile phone packaging box very thin, and the red and white color matching is quite fresh. The design of the accessories of Yijia mobile phone is also quite special. The data cable is flat wire, with corresponding cable ties, and the interface is gold-plated. The same red and white color matching makes the whole phone feel very good. In addition to the special appearance design, the card needle also has a small protective sleeve, which is convenient to carry.

In terms of appearance design, Yijia mobile phone does not surprise people, but it has a familiar taste. Because the physical touch key logo is very dim, the overall effect is quite good when the screen is turned off. Once the overall design of mobile phones is symmetrical, obsessive compulsive friends will definitely like it.

From left to right on the top are the front camera, indicator light, sensor and earpiece.

The physical touch key of Yijia mobile phone has a weak sense of existence. Whether the key backlight is on or not, it is hard to see clearly when used in a well lit environment.

The OnePlus mobile phone adopts a design called the floating screen, which makes the screen slightly smaller than the border, and it really has a floating feeling. Yijia claims that after using the floating screen, the probability of dropping the screen of the mobile phone can be reduced by about 7%. At the same time, the silver frame that runs through the whole body reflects dazzling luster after processing.

The double speakers at the bottom have a loud overall volume.

The back can be said to be the biggest talk of Yijia Mobile. There are many patterns on the back cover of Yijia mobile phone. In terms of materials, besides the common plastic materials, Yijia mobile phone will also have wood, bamboo, denim and Kevlar materials, which are quite special. Even the ordinary black and white color has its own mystery. For example, the white color, called Baby Skin, uses a special coating from Kasu in Japan and is made of cashew nuts. It is really smooth and comfortable in touch.

It's a pity that a mobile phone can't replace the back cover and remove the battery freely, but the official said that it will let professionals replace the shell for consumers at the designated service point.

Yijia mobile phone uses a 13 megapixel rear camera and dual LED flash lights. There may be a very small gap between the camera and the back cover due to the material of the back cover, mainly because the gap on the left and right sides of the camera is different in size. But the gap cannot be inserted with needle or paper, so don't worry too much.

Yijia mobile phone uses a 5.5 inch screen, and its three dimensions reach 152.9 * 75.9 * 8.9mm. The pressure is slightly higher when holding it with one hand. The area for single hand operation is shown in the figure above. One hand use of Yijia mobile phone requires adjusting gestures to operate some areas. It should be noted that when a phone is held with one hand, it will feel like a poke in the palm of the hand.

Screen effect:

The OnePlus mobile phone uses a 5.5 inch IPS screen from JDI, with a resolution of 1920 * 1080, and supports Ram automatic power-saving refresh, CACB backlight brightness adjustment, ultra sensitive touch and other technologies. Yijia Mobile claimed that its screen provides 2000:1 contrast and 480 nits brightness.

In actual comparison, Sony Xperia Z Ultra is used to compare with vivo Xplay 3s. From left to right, the figure above shows Sony Xperia Z Ultra, Yijia Mobile vivo Xplay 3s。 In comparison, Yijia mobile phone and vivo Xplay 3s have a certain degree of whiteness, but the feeling is not serious in daily use.

In the white performance, Sony Xperia Z Ultra turns yellow on the whole, while the bottom of Yijia mobile phone turns yellow obviously. Yellowing at the bottom of Yijia mobile phone is not obvious in daily use, but it is more obvious in white background, such as Weibo client. According to its official explanation, this is because the screen LED backlight is designed at the bottom of the screen.

In the actual photo comparison, Yijia mobile phone performs well.

In terms of visual angle, there is no problem with a mobile phone whether it is a small side angle or a large angle that is rarely encountered. On the diagonal, there will be some whitening.

System UI:

Yijia mobile phones do not have their own ROMs. Compared with the traditional way of making ROMs first and then hardware, Yijia mobile phones are adapted to a variety of popular ROMs in the market, such as MIUI, Color OS, CM and Hammer. Personally, I think this is a flattering but very good move.

From the current situation, it seems that Color OS will be pre installed on the Yijia mobile phones sold in China, while CM will be pre installed abroad. It's a pity that the pre installed Color OS version of Yijia's mobile phone is relatively old. Although there is no castration in its functions, such as various gesture body senses and corresponding display settings, it's a pity. Specific use experience can be referred to《 A turn of heart? OPPO N1 experience evaluation 》The system UI section in.

In the system, there is only one dedicated to OnePlus, that is, tuning. Tuning is a console, which can be simply regarded as EQ system. It cooperates with MAXXAUDIO and has a large number of detailed adjustable projects. In addition, there will be a large number of parameter schemes that can be adapted to different brands of earphones, which is still interesting.

Shooting ability:

The shooting hardware of Yijia mobile phone is as powerful as the configuration. The sensor is Sony IMX21413 million pixels and F/2.0 aperture, as well as 6P lens. As for the shooting interface, the Color OS is also familiar. It is still switching between various scene modes, and the overall interface design is relatively simple and easy to use. Unfortunately, the white balance can be adjusted, iso、 Exposure cannot be adjusted. What's more interesting is that Yijia mobile phones also have image quality, slow shutter speed up to 32s, and Raw format options.

There is a mode called Picture Quality Plus in Yijia mobile phone, and no detailed information was found to explain the difference between this mode. During the shooting process, there will be a post-processing process. But from a large number of shooting samples and experience, the actual difference is not too big.

As shown in the figure above, the image quality is turned on and the image quality is turned off and the contrast is added. The former has an iso of 800, while the latter has an iso of 500. The overall feeling is not too great except that the picture is brighter. After more than two weeks of use, the improvement of image quality can be ignored in the environment with sufficient light.

In some extreme cases, image quality plus has a good advantage. On the road map, you can see the building design clearly when you turn on the image quality plus and turn off the image quality plus, while when you turn off the image quality plus, it is much darker overall. However, in this extreme case, it is not very useful to turn on the image quality enhancement, so we can only hope that the subsequent firmware optimization and upgrade will have better performance.

Relying on quite powerful shooting hardware and relatively good training level, Yijia's mobile phone has performed quite well in shooting. In the daytime and indoor environment with sufficient light, the focus speed, resolution and white balance are all very good. In terms of color performance, Yijia mobile phones are also more accurate, and the overall atmosphere and appearance are good.

In terms of night performance, Yijia mobile phones are prone to focus failure, but they can understand. Under the condition of accurate focusing, the overall exposure control is very good, and zooming in details is acceptable. In addition, there is no obvious weakness in the overall performance of mobile phones, and all aspects are quite good. However, since the system has not been specifically optimized, I feel that there is still much room for upgrading and optimization.

In terms of front camera, Yijia mobile phone uses a 5 megapixel camera and has common beauty functions. What needs to be complained is that the front camera is turned on by default to enter the beauty mode, and the default beauty effect is too exaggerated, the actual effect is slightly scary. Therefore, the front camera sample does not open the beauty.

Compared with the rear camera, the front camera of a mobile phone has more complaints. If the glare is serious, the overall sharpening is also quite obvious. Sharpening affects the appearance. As shown in the above figure, after the two Showgirls zoom in, they can clearly see that excessive sharpening leads to rough skin and short hair. But by horizontal comparison, the front camera of Yijia mobile phone is not much better than most of the 2 million pixels.

Performance and endurance:

The hardware configuration of Yijia mobile phone is quite luxurious, MSM8974AC processor and 3G RAM are currently the flagship of the flagship. The dazzling performance in the theoretical run is enough for performance controllers to like. Before the more powerful Snapdragon 805 or 810 is officially launched, there is no problem for the first camp of stable performance.

Not only does the theoretical run share the power, but also in the actual game test, it has a fairly high fluency. The overall frame number is always between 30 and 31, without jamming.

After 15 minutes of wild racing, the maximum temperature of one phone is at the camera part, and the maximum temperature measured is about 39 ° C. In this hardware configuration, it is a good result.

One mobile phone uses a non detachable 3100mAh battery. Its capacity is quite enough, and the screen is only 1080P. The actual endurance level is quite good. After 15 minutes of wild racing, the power consumption is 8%. According to my daily use, there is still about 35% power surplus from leaving at 8 o'clock to getting home at 8 o'clock at night. Most of the time, WiFi is opened indoors for daily operations such as microblog refresh.

Other matters:

When a mobile phone is held by one hand, it needs to adjust the holding posture to operate the top of the screen. The white version is easy to fall due to the smooth coating on the back. This is something to be aware of.

The pin hole of Yijia mobile phone is smaller than that of common mobile phones, so pay attention to compatibility when using other pins. The black version of the Yijia mobile phone is perfectly made on the gap of the SIM card slot. If you don't look carefully, you can't see where the card slot is.

The frame of Yijia mobile phone is generally rigid, and it is easy to be sunken in case of collision. Attention should be paid to daily use. And the gap between the top and bottom frames and the screen is easy to hide dirt, which needs to be cleaned.

The back coating of a mobile phone is not permanent, and there will be some wear marks after a long time of use. After more than two weeks of use, the white Baby Skin coating tends to turn black in the arc part of the corners and cannot be wiped off.

Summary:

Although there is not much surprise in the appearance design of the Yijia mobile phone, the powerful hardware configuration and camera capability, plus small highlights such as accessory packaging design and back coating, and finally the starting price of less than 2000 yuan. It can be said that one plus mobile phone is a good choice in the sector of 2000 yuan or even 3000 yuan. While maintaining the cost performance ratio, it also officially adapts to many popular ROM/OS, which is also the choice of many troubled players. In this respect, Yijia mobile phones are like angels.

For those who like it very much, Yijia Mobile has no characteristics in its appearance design and system UI, just like a hundred clothes. Although the packaging design is quite special, the mobile phone is used after all, and it needs to adapt to many ROM/OS, so the update speed and special optimization are still inferior. I hope that Yijia mobile phones will have greater action and change in the next generation of products, or in the first product.
