Disadvantages: 1. The appearance design is flawed, the creases are too obvious, and the back is almost a plane, but the camera protrudes, causing the phone to "play allegro" and the experience is not good. 2. The system is not fully compatible with the folding screen; 3. The awkward screen design is not suitable for gaming; 4. The main camera does not have OIS optical image stabilization.
The operating environment of this tutorial: MIUI 13 system, Xiaomi MIX FOLD mobile phone.
Xiaomi MIX FOLD is the first folding screen mobile phone released by Xiaomi on March 30, 2021. MIX FOLD adopts an inward folding design and a side fingerprint solution. The inner screen is an 8.01-inch full screen; the outer screen is a 6.52-inch punch-hole screen in the upper right corner. It uses a ceramic back cover, with golden thin lines added to the middle frame and volume keys, and a black ceramic back cover.
As Xiaomi’s first foldable screen phone, everyone is still paying a lot of attention to Xiaomi Mixfold. Let’s talk about the advantages and disadvantages of Xiaomi MIX FOLD.
Advantage 1: Parallel window, efficient operation is more suitable for life
Let me first talk about a scenario of using the machine in life. If you want to buy a piece of clothing on a certain treasure, you can go through By entering keywords to search, you will find a lot of products. Without this mode, most people's operating habit is to add all the products they are interested in to favorites or shopping carts at once, use them as preliminary selections, then open favorites or shopping carts, switch interfaces back and forth, and proceed to the next step. Second round of screening.
With parallel windows, the phone can open two windows of an application at the same time. When using it specifically, open a shopping app on the inner screen, open the tentative product on the right part, and slide up and down to browse on the left part. When you find a product that is more interesting than the tentative product on the right, click directly and the product will appear in In the interface on the right, it becomes a new tentative product. This can save a lot of switching interfaces back and forth, making the operation more efficient.
This function can be applied to a wide range of scenarios. For example, when using QQ, you can read the messages in the group on the left half and the space on the right half, without delaying either. Many folding screen mobile phones have similar functions, but it is almost impossible to transplant them into ordinary mobile phones. Because of the limitations of screen size and aspect ratio, forced transplantation would be useless.
It is very simple to open the parallel window of Xiaomi MIX FOLD. Find "Application Settings" in the settings interface, select "Parallel Window", and you can find the switch interface of a bunch of applications. Applications with this feature turned on can open two windows of an application at the same time. From the current point of view, most applications that have a superior-subordinate relationship in operation are supported, and the functional coverage is very wide.
Advantage 2: Small window mode on a large screen, small windows have greater practical value
Small window mode is not unique to folding screens. But the folding screen can bring out the greatest value of the small window mode.
The picture above is the state of Xiaomi MIX FOLD when using the small window mode on the internal screen. Because the screen is larger, the application field of view in the lower layer of the floating window is wider and the proportion of occlusion is It will not be too high and will have less impact on the line of sight. There are many practical scenarios that we can apply it to. In addition to chatting and watching TV, we can also conduct video conferences and query relevant information for online reporting. Even a mobile phone can provide very powerful productivity.
Xiaomi MIX FOLD's small window startup is the same as that of all MIUI devices. Under the multi-tasking interface, select the small window in the upper left corner Application, a list of applications that support small window applications will pop up. After selecting an application you want to use, the application will directly appear on the desktop in the form of a floating window. At this time, both the floating window and the underlying desktop can be operated. As far as the process is concerned, it is not complicated and there is no particularly large learning cost.
Advantage 3: Four speakers, Harman Kardon tuning, more three-dimensional effect
Xiaomi MIX FOLD uses four speakers The design includes a pair of 1216 ultra-large amplitude speakers, equivalent to a 1.34cc sound cavity, with extraordinary loudness. In terms of body design, there are two speaker holes on the top and bottom, both of which are not hidden. If you listen to the sound effects, the sound field of the four speakers is very wide and the three-dimensional effect is very strong.
The author has reviewed hundreds of mobile phones. I’m not saying that I’m not talking about it. Xiaomi MIX FOLD is the one with the best external playback effect among the models I have tested. There is no one among them. Many seemingly ordinary music cannot be played. You can hear the goosebumps. The low frequency dive is quite deep, so deep that it is ethereal, and the high frequency is played at the loudest without breaking the sound. It is really difficult to achieve the ultimate in these two points at the same time. The four speakers are tuned by Harman Kardon, and the sound effect is indeed outstanding.
Advantage 4: The introduction of liquid lens ensures consistent zoom style
The top lens in the illustration is 8 million The innovation of the pixel telephoto macro lens is the use of a liquid lens design, which replaces traditional optical lenses with flowable liquid and adjusts the internal liquid pressure or other physical properties under external drive, thus changing the external shape of the lens. The focal length is not involved, but changes in focal length and focus are achieved. Therefore, this 8-megapixel lens has both telephoto and macro functions. It supports 3cm macro, 3x optical zoom, and can achieve up to 30x digital zoom.
In the current lens division of mobile phones, telephoto and macro are both implemented by two lenses. Among them, telephoto shooting is either done with digital zoom of the main camera or with a separate telephoto lens. To perform macro, either shoot with a separate macro lens, or have an ultra-wide-angle lens do it for you. With a good telephoto lens, there isn’t much of a problem when shooting at telephoto, but the problem lies in macro.
If you use a macro lens to perform macro photography, it is tragic for mid-to-low-end mobile phones, because the macro lenses of many mobile phones in this price range are just make-up. Yes, it is only 2 million pixels, and the bottom is still very small. When the phone is close and the light is blocked, the photo will often be very dim; if you use an ultra-wide-angle lens for macro, the ultra-wide-angle lens will have some distortion when processing both sides of the frame. , which may be magnified during macro tasks. The most important point is that each lens has its own characteristics. Different lenses will have more or less differences in style even after post-production adjustments. Therefore, the introduction of macro lenses can ensure the unity of style between macro and telephoto to the greatest extent.
Advantage Five: In handheld PC mode, the mobile phone can become a hard-core productivity
Open the internal screen of Xiaomi MIX FOLD, the screen three Swipe left to quickly enter the handheld PC mode, which is specially designed for business offices.
As far as the overall style is concerned, it is very similar to Windows. As long as you have used a computer, you will be able to get started without any tutorials at all.
#Long press on a blank area of the desktop to quickly create new files and folders.
During our testing, we found that the handheld PC mode of Xiaomi MIX FOLD can open up to 5 windows. If you want to open the sixth window, an already opened window will be deleted. window is minimized. I don’t know yet whether the “5” in this “5 windows” is a fixed value and whether it will be affected by the memory space occupied by the application. Overall it's quite convenient.
Disadvantage 1: The appearance design is flawed and the creases are too obvious
When I unpacked this phone, I took it After weighing it in my hand, my first impression is that the design of this phone is very reasonable, because it is basically a symmetrical design, the center of gravity is on the central axis, and the thickness of the body on both sides is also about the same value. There were very few folding screens in the past. Cell phones do this. But when I laid it flat on the table, I changed my mind.
#The back is almost a flat surface, but the camera protrudes, causing the phone to "play allegro". This experience is really bad. For example, if you are watching TV on a green train with your phone on it, and your phone is placed on the table, and your screen shakes up and down as you accelerate, are you comfortable?
On the contrary, for some less symmetrical folding screen mobile phones, the "allegro" phenomenon is not so obvious. Because of the seam in the middle, they form a large-area support line, which can play a good buffering role. I believe Xiaomi designers had a good intention, making it symmetrical and more comfortable to hold the phone, but they may not have considered the impact of the camera protrusion on the flat placement. It’s 2021, and I don’t expect mobile phone manufacturers to “recess” the camera, but I hope Xiaomi or other accessory manufacturers can make a mobile phone case that “recesses” the camera to avoid that embarrassing shaking.
In addition, the creases of Xiaomi MIX FOLD are still relatively obvious. In the large screen mode, you can see obvious creases from any angle. Creases are a common problem for folding screen phones, but I didn’t expect Xiaomi MIX FOLD to be so conspicuous. I don’t know if it will be much better to use glass when folding screens are completed. Nowadays, even folding screens with glass screens have low Mohs strength.
Disadvantage 2: The system and the folding screen are not fully adapted
One of the more essential tests of the folding screen is the interaction between the internal and external screens. cut. However, many details of Xiaomi MIX FOLD have not been optimized well. Many application interfaces cannot automatically switch when the internal and external screens are switched between each other. The screen will freeze when closing or opening it. You need to press the power button to turn on the screen again. After turning on the screen, unlock the desktop to return to it. The interface of the original application. In addition, there are many bugs. When the internal and external screens of some applications are cut from each other, there is a certain chance that the ratio will be forcibly stretched, just like the picture above.
The internal screen is a large screen, split screen should be very effective, but in Xiaomi MIX FOLD, quite a few third-party The proportion of the application is not suitable. Whether it is placed vertically or horizontally, the interface is forcibly stretched. Although the system prompts "the application may not run properly in split-screen mode", it still feels a bit strange, just like buying a baby at an exorbitant price, and the seller said in a very inconspicuous place that the baby has a flaw in a certain place. This kind of system has not solved the split-screen application for the time being. Shouldn't it be locked and prohibited from starting split-screen?
Although it is not very comfortable to use, it can be improved through later OTA. I wonder when the MIUI team will remember their folding screen products.
Disadvantage three: Awkward screen design, not suitable for playing games at all
At the press conference, Boss Lei gave high praise to the gaming performance of this phone Yes, but our actual gaming experience is quite poor because its screen is anti-game design. Taking "Honor of Kings" as an example, we took a few photos comparing Xiaomi MIX FOLD and ordinary mobile phones in the game.
Let’s talk about the external screen first. Xiaomi MIX FOLD uses a 27:9 screen ratio. From the same position, not only can you see the Three Bear Pit, but you can also see the river on the right. There is some grass on the side, which is a good thing, but the two big black edges in the picture are really eye-catching.
The most critical point is that the position of the buttons is still in the original proportion. Even if it is customized, it cannot be moved to the sides. This means that your fingers must be closer to the center of the screen when playing games. This design is really "wisdom".
Talking about the external screen, the field of view on both sides of Xiaomi MIX FOLD has become narrower, and the field of view at the bottom has become wider. This adjustment of the field of view ratio is absolutely perfect for games. debuff.
Taking Zhong Kui as an example, in the same position, using the Xiaomi MIX FOLD to hook out the hook, it flew directly out of the screen. In fact, in the game "Honor of Kings", Zhong Kui's skills are not very far away. The poke range of many archmages is farther than Zhong Kui's second skill. My friends joked after seeing this phenomenon during my test. Tao: Use Xiaomi MIX FOLD to play "Honor of Kings", don't play in the middle lane.
Another point is that even if you don't play "Honor of Kings", it's awkward to play other games because its refresh rate is only 60Hz, and many games have enabled 90FPS and 120FPS modes. If you can't open high frames on a large screen, isn't this a waste of watermelon and sesame seed?
Disadvantage 4: The main camera of a thousand yuan machine does not have OIS optical image stabilization
The introduction of the liquid lens is the highlight of Xiaomi MIX FOLD, but this cannot cover up the embarrassment of the main camera of the thousand-yuan machine. The main camera sensor of this machine is Samsung ISOCELL HM2, which is the same model as its own thousand-yuan machine Redmi Note 9 Pro, and does not have OIS optical image stabilization. As the saying goes, night scenes are the watershed that determines the quality of a camera's photography. By comparing the night scene samples, everyone should know the true photography capabilities of this phone.
(▲Xiaomi 11 Ultra, Samsung ISOCELL GN2, 1/1.12 inch)
(▲Redmi Note 9 Pro, Samsung ISOCELL HM2, 1/1.52 inch)
(▲Xiaomi MIX FOLD, Samsung ISOCELL HM2, 1/1.52 inch)
Comparing the sample photos of the same lens position, you can find Xiaomi MIX FOLD The night scene performance is at the same level as the Redmi Note 9 Pro. Compared with Xiaomi's own flagship Mi 11 Ultra, the colors are dull and the smearing is more serious. The overall tolerance is not good, the bottom is too small, and it is too suppressed.
Is Xiaomi missing a camera? Bloggers really don’t think so. Samsung GN2 can be launched at the launch, and it can be used for folding screens. In addition, the folding screen itself is a muscle-flexing product, and any manufacturer will be willing to pile up materials. The reason for this is my personal guess (only my personal guess) and it is related to the Pengpai C1 imaging chip that Xiaomi MIX FOLD focuses on marketing. This ISP chip may not be able to adapt to those larger cameras.
