everybody knows，In the field of consumer electronics，When innovative products first appeared，There will always be "bugs" of one kind or another。But if you want to really make a judgment on the future of this type of product，Have to be more patient，Wait until the second generation，Even after the third generation，Only then can you draw a conclusion。Nowadays, foldable screen mobile phones are in an increasingly perfect stage，There are more than one on the market、Products close to "complete" exist，For example, Huawei Mate X2 and Samsung W21 5G。
If you want to know how folding screen experience has developed today，Or you have the desire to buy but don't know who to choose，Hope this article will be helpful to you。
first，Let's introduce the two players。Huawei Mate X2 and Samsung W21 5G are both their own third-generation folding screen products，All use internal folding、External small screen、Built-in large screen design，The specific parameters are as follows：
It should be noted that，In addition to W21 5G，Samsung has another folding screen phone with similar configuration：Samsung Galaxy Z Fold2 5G。Both phones only have dual-slot and dual standby，5Number of G-bands，Different appearance and battery capacity。So this article compares Huawei Mate X2 and Samsung W21 5G，It also has reference value for users who want to buy Samsung Galaxy Z Fold2 5G。
"Inside fold" and "Inside fold"
On traditional flagship phones，The focus of comparison is often on hardware speed and cameras.。But the configuration has been fully loaded、On the folding screen flagship priced at nearly 20,000 yuan，The shaft and screen are the real hardware core。
The biggest difference between the folding mechanism of the two mobile phones is the state after being completely closed.。The two parts of Huawei Mate X2 are completely attached together。If you use a flashlight to shine from one end，The other end will hardly transmit light。Samsung W21 5G has a gap as thick as a bank card on the side of the shaft。
Samsung does this to avoid severe creases caused by excessive folding。So how did Huawei relieve the crease?
Although from outside，Huawei's tight stitching fold means sharp folding angle。But inside，When you start folding，The screen is not bent directly，Instead, it moves inward toward the thickness of the fuselage。After folding，The side of the folded part of the screen is a curved shape similar to a water droplet.。Compared to "inside fold"，Huawei's design should be called "inner folding"。
Huawei's design does not sacrifice appearance，Also prevent foreign objects，But a small amount of internal space of the fuselage was sacrificed，A fixed folding angle range is small，Not as stable as Samsung's fixed；Samsung's design does not take up much internal space，Can be fixed at almost any folding angle，But the appearance was sacrificed、Feeling and foreign object protection。The two mobile phones made their own choices，Which design is better，Varies from person to person。
The main difference is the external screen experience
Different from the folding method of the shaft，The screen experience of the two mobile phones is objectively different，The difference is mainly reflected in the external screen。Samsung realizes the importance of external screens to users，So the size and width of the external screen are increased on the Galaxy Z Fold2 5G and W21 5G (compared to past products)。But this external screen is still different from a traditional mobile phone screen，Mainly reflected in the display ratio、Font size、Fluidity and feel。
Samsung W21 5G, which is much narrower than normal phones, is very suitable for long pictures，But it's not suitable for regular content。Especially the video、Games and maps, etc.。A narrow screen also means a small display area，The font is smaller than that of a regular phone。Because the outer screen border is not as wide，Plus the protrusion on the side of the shaft，The grip of this phone is different from that of a traditional phone。
If it's smooth，Samsung W21 5G's external screen supports 60Hz standard brush，It's a bit lower than the 120Hz of the inner screen。
External screen of Huawei Mate X2，Can be summarized in one sentence：“Same as a traditional mobile experience”。High brush (90Hz)、high resolution、Normal ratio，And the feel that is very close to traditional phones when held，All are the features of Huawei Mate X2。
Speaking of the inner screen，It has become a "partial" situation again，Because the internal screen quality of both phones is very good。size、Proportion、No one has the best pixel density。all in all，Whose screen is more suitable for you，Depend on personal usage habits。
Multitasking，Single task large screen optimization，Who is stronger?
If the screen quality and rotation axis are the hardware core of the folding screen，Then the core of their software is large-screen adaptation。In their respective operating systems，Both phones have some functions that utilize large-size internal screens.。
Samsung has two main，The fingerprint sensor slides the notification bar and multitasking processing respectively。There are two main aspects of Huawei，Parallel vision and smart multi-window。Parallel Vision uses large screens to improve the experience of a single APP，Smart multi-windows optimize multi-tasking。
Before entering the details function comparison and demonstration，You can take a look at the summary of test results first：
Now let's go into the details，Samsung W21 5G has 5 ways to enter multitasking，as the picture shows：
Huawei Mate X2 has two ways to enter multitasking，as the picture shows：
After entering multitasking，Both phones have two display modes，floating window and split screen。
In floating window mode，Samsung W21 5G users can move the floating window position、Adjust the size of the floating window (no limit on the ratio)、Change the transparency of the floating window、Quickly fold/restore the floating window、Restore full screen display、Close the floating window、Switch between floating window and split screen。
Huawei's side，The floating window mode allows the user to move the floating window position、Adjust the size of the floating window (limiting ratio)、Quickly fold/restore the floating window、Restore full screen display、Close the floating window、Switch between split screens of floating windows。
In the "Quickly Collapse/Restore Floating Window" item，Huawei Mate X2 digs deeper，Because it allows users to store multiple APPs in the closed floating window bubble，Convenient to use later。
In split screen mode，Although the operation methods of the two phones are different，But the function is the same。All can change the split screen ratio、Change the APP location、Switch from split screen to floating window、Close the APP and restore full screen。
After watching so many demonstrations，Let's summarize it for everyone。Samsung's floating window has higher freedom of operation，But lacks the storage function of Huawei's multi-floating windows。split screen，Samsung and Huawei have the same functions，Just the operation method is slightly different。
So how about a single APP experience? it is known，iPad will use the special "HD version" APP to improve the large-screen experience，However, there are few HD version apps on Android。Basically all APPs are enlarged versions of mobile phones on large-screen Android devices，This is the case with Samsung W21 5G。
Huawei Mate X2 brings the "parallel vision" of its own tablet to the folding screen phone，Changed the traditional single app experience。Parallel horizon allows users to use a single APP，The current page is displayed on the right side of the screen，The previous page is displayed on the left。
Under the default settings of Huawei Mate X2，When expanding the screen and running a third-party app in full screen，Parallel horizons will be automatically activated。If not activated，Or it is not enabled in the parallel visibility setting.，Or the APP does not support parallel vision。
Audio and video entertainment is the most attractive thing about folding screens
As the saying goes, “Performance before buying”，I love Qiyi after buying”。Large screen can improve multi-task efficiency，But foldable screen mobile phones are still best at audio and video entertainment。While playing games and watching videos，Huawei Mate X2 and Samsung W21 5G can switch screens，Take advantage of larger display area。but，Restricted by mainstream video proportion，Watching videos with large screens still has black edges。
Fortunately，While playing games and reading comics，Large screens can be fully utilized。At this time, the experience of the two mobile phones is no different from that of the tablet computer。
Something more interesting，Huawei will have a brief proportional adjustment when switching between the inside and outside screens of the game，And the time taken for different games is different。However, at the speed of normal humans，The screen ratio will return to normal before re-retrieval operation，Does not affect normal use。
It is estimated that there is room for a larger speaker，The dual speakers of both phones sound very much like tablets。Huawei Mate X2 comes with Huawei Histen sound effects (only by wearing headphones)，Samsung W21 5G comes with Dolby Panoramic Sound，Can further improve the listening experience。
sometimes，Folding screen mobile phones are not necessarily the office tools of business elites，Instead, it is more suitable for the general public's audio and video entertainment。
Which form is the future?
Because of the problems with early folding screen products，There are still many people who don’t have a good impression of folding screens。But for now，The best folding screen product that the industry can produce，Already competent for daily use。In the article, we have found the results of our optimization of Huawei Mate X2 and Samsung W21 5G large-screen，It also proves that the experience of foldable screen mobile phones under large screens is no worse than that of tablets of the same size.。
so，The number one "killer" that affects folding screens to become the mainstream form of flagship phones，Not a software adapter，Not even creases or prices，But other factors：Weight and thickness。Due to technical limitations，We can't do the ultra-thin "canvas" mobile phones in science fiction movies。So at this stage，Regardless of which folding screen you choose，You are all using a thin and light exchange of traditional phones that can be placed in your pocket to experience it。
If you are willing to bear the weight of the folding screen，Who should I choose? We need to understand before answering this question，Although both Samsung and Huawei use internal discounts，But they are taking two different paths。Huawei Mate X2 is a combination of normal mobile phones and tablets。Use external screen separately，It's a complete mobile phone；Use the inner screen separately，It is a tablet that pursues the ultimate (no holes)。
But Samsung W21 5G，But it is a "folding screen mobile phone" in the traditional sense。The big screen it folds up，It is to make the mobile phone experience more pleasant (the inner screen has a front camera)，Instead of completely restoring the tablet experience。Samsung chose this path，It means treating the external screen as an attachment。External screen comes with mechanical watch screen protector，It's like a secondary screen that uses a flip phone to see the time，I didn't want to replace the normal mobile phone screen。
so，Who to buy，It depends on what kind of experience you need，It is Huawei Mate X2 with a "complete mobile phone + tablet" experience，Or is it a "large-screen mobile phone" Samsung W21 5G?
