The 2020 Snapdragon 865 is Qualcomm's most successful flagship SoC in recent years, and the Kirin 9000 in the same year became HiSilicon's masterpiece. Subsequently, the 2021 Snapdragon 888 permanently changed the heat dissipation configuration of Android phones, and the 2022 Snapdragon 8 Gen 1 went further, and even the game phones that actively dissipated heat with fans continued to upgrade heat dissipation.
At that time, the Snapdragon 810 model was not sold in large quantities, so the public actually felt the enthusiasm of mobile SoC for the first time, which was two years of soaring GPU performance of Android mobile phones, but it was also two years of Android CPUs standing still.
The following story summarizes the chain of logic:
SoC: High power consumption> heat generation> downscaling> stuttering
Manufacturers: Enhanced heat dissipation > stricter temperature control> frequency reduction > Caton> a meal operation is fierce, the performance is not as good as the 865. Subsequently derived "more aggressive running score whitelist + game resolution reduction> the emperor's new clothes"
Media: The tester dispatches aggressive performance is good> push down the frequency of the firmware after the sale> user results and media results conflict> the first media is sprayed > the point is useless
Users: Seeing the mess for two consecutive years> manufacturers" do not adjust well, do not issue a declaration > the actual measurement of the face > actual " do not adjust, good no, release"

The enthusiastic Snapdragon 888
iPhone users and non-mobile phone users may not understand why the Android camp has been wailing for two years, let's sort out in chronological order, what exactly happened. After all, everyone is used to the days when mobile phone performance increases by 20%-30% per year, but in fact, the Android camp has already experienced the situation of standing still.
The story begins with the release of the Snapdragon 888 at the end of 2020. The latter debuted Samsung's 5nm process and also launched Armand's first true super-large nuclear architecture, Cortex-X1. Before the release of the Snapdragon 888, the Weibo Big V digital chat station said that the Snapdragon 888 has strong performance and low power consumption, and everyone is full of expectations for the future.
Geek Bay video
The Xiaomi Mi 11, which debuted the Snapdragon 888, went on sale on New Year's Day 2021, and Geek Bay's "Snapdragon 888 Performance Analysis: Rollover!" on January 6th "" kicked off the hot year of Snapdragon 888. Whether the Snapdragon 888 overturned has become one of the hottest topics in the aircraft circle in 2021.
The daily power consumption of the Snapdragon 835 in 2017 was in the order of 3W, and the subsequent Snapdragon 845, Snapdragon 855, and Snapdragon 865 power consumption "steadily increased" and came to the 5W to 6W range. The X1 large core of the Snapdragon 888 can run to 3.3W with a single power consumption, and the CPU multi-core power consumption directly soars from 5.9W of the Snapdragon 865 to 7.8W. The power consumption and energy consumption ratio curve of its GPU part is also not ordinary, so that many people in the early days thought that the GPU of the Snapdragon 888 only continued to overclock on the basis of the Snapdragon 865 and led to high power consumption.
Because the power consumption data of the Snapdragon 888 is abnormally high, there was also a physical disassembly later, and the physical method of "fake battery cable" was used to forcibly test the power consumption. Although the result is 2W lower than the software test power consumption, the power consumption of the whole machine still reaches the 10W level, and the instantaneous power consumption is close to 11W.
The rise in power consumption has led to the "interactive running software" "Original God", the Snapdragon 888 model can easily break through 45 degrees, and some extreme models can rush to nearly 50 degrees. 3C digital products have a 48-degree temperature line to prevent users from being "low temperature burned", so almost all Snapdragon 888 models have encountered phenomena such as forced brightness reduction of the screen and system lock frames (except for game phones).
What follows, many users may have heard about. The weather turned warm, first a large number of users reported that the Snapdragon 888 flagship would have the problem of heat caton, and even triggered an overheating warning. Subsequently, a number of manufacturers rushed to push the down-frequency firmware before the summer, using the method of limiting performance output to reduce heat generation to suppress the enthusiasm of the Snapdragon 888.
This was followed by a large number of feedback and dissatisfaction that the performance of the Snapdragon 888 was not as good as that of the Snapdragon 865 after the frequency reduction. The most tragic millet, one is the first Snapdragon 888, the second is the early implementation of the active scheduling strategy of "born for fever", and there is an incident of Xiaomi 11 burning Wi-Fi due to high temperature in the summer. Although there are quite conscientious replacement policies and model improvements in the follow-up, Xiaomi, which was once bitten by snakes, subsequently became the most conservative manufacturer of temperature control and frequency control.

Snapdragon 8 Gen 1: Fire!
Time can dilute everything, everyone calmly accepted the enthusiasm of snapdragon 888, and even cordially ridiculed "only snapdragon 888 still gives me a little warmth in winter." Then, the Snapdragon 8 Gen 1 came.
Rice evaluation data
A generation of new people is better than the old, and the title has also been upgraded from "Fire Dragon" to "Fire Dragon". The new X2 big core, single core power consumption set a new record for the Snapdragon 888, jumping from 3.3W to 4W level, and the new A710 large core also has 2.1W (3 in the middle core). The power consumption of the new Adreno GPU in the GFXBench Manhattan 3.0 scene also jumped from 8.2W of the Snapdragon 888 to 10.9W.
This is a power consumption performance that has never appeared in the history of mobile phone SoC, and the cpu peak and GPU peak power consumption have both exceeded 10W, which is like a tablet, or even a thin and light power level. The Apple M1 and Snapdragon 8 Gen 1 have achieved their respective "PC-level" standards in different ways.
The last so-aggressive phone SoC was the Snapdragon 810 in 2015. But unlike 7 years ago, the current mobile phone manufacturer has enough technical reserves to suppress its heat for a short time. The uninhibited power performance of the Snapdragon 8 Gen 1 has made all Android manufacturers, including Samsung, emphasize their own cooling configuration at the press conference. "How to Train Your Dragon" has changed from the previous ridicule to the goal of all Android manufacturers.
Superimposed on the efficiency problems of some domestic 32-bit applications at this stage (in the new architecture of Snapdragon 8 Gen 1, only 3 of the 8 cores can support 32-bit applications), which aggravates the heat generation and stuttering problems in old applications. You know, the winter and spring season, which is the most friendly to mobile phone fever of the year, is coming to an end, and the summer that is more sensitive to temperature is just around the corner.
The same fever problem also appeared on the Exynos 2100 and Exynos 2200 using the same Samsung 5nm/4nm process (the European version of the Korean version of the Samsung Galaxy S21 series and the European version of the S22 series). The latter is the first mobile SoC equipped with AMD RDNA2 GPU, which not only has the absolute GPU performance not beaten the Snapdragon 8 Gen 1 and Tianji 9000, but the CPU part is also the same as the Snapdragon 8 Gen 1.
On the same timeline, in December 2021, when users were suffering from fever, MediaTek released the first SoC that truly surpassed Qualcomm - Tianji 9000. MediaTek's operation of taking the engineering machine to the media for testing 3 months before the mass production machine was sold was also unprecedented.
TSMC's 4nm, more sincere stacking, the overwhelming CPU on the test machine and the energy efficiency ratio have all made everyone look forward to it. "Dry flip X pass! The cheers of the world's people suffering for a long time" were endless. In the end, the much-anticipated Tianji 9000 was first launched by OPPO Find X5 Pro Tianji Edition PPT and physically launched by Redmi K50 Pro.
The MediaTek Tianji 9000 mass production machine does show the energy consumption ratio of crushing snapdragon 8 Gen 1, but the peak power consumption is still exaggerated, and the energy consumption ratio is not as good as that of the engineering machine. Therefore, there is a stem: MediaTek gave the test machine in advance to prevent the chip from being adjusted badly by subsequent manufacturers. So far, in 2022, the three new SoCs with the new architecture of armv9 are all "hanging on the color" in the energy consumption ratio.
There is also a small episode. Android flagships such as the 2021 Samsung Galaxy S21 Ultra, one plus 9 Pro and OPPO Find X3 series are equipped with a more power-efficient LTPO screen (a power-saving technology that can dynamically adjust the screen refresh rate), and the 2022 flagship is equipped with a more power-efficient LTPO 2.0 screen in large quantities. This 2nd generation LTPO screen happened to meet the Snapdragon 888 and Snapdragon 8 Gen 1, and the electricity they saved was simply not enough for SoC to eat, so there was a "thing about the Nachijie engine oil tiger manufacturers to desperately optimize the tire fuel saving".

Reverse upgrades, experience upside downs, and all sorts of awkwardness
"Hot" itself is not fatal, and the fatal thing is that CPU performance is also standing still. The energy consumption ratio (ratio of performance to power consumption) and the concept of thermal load carrying are involved here:
1, energy consumption ratio: if the chip can complete the task at a faster speed, and then return to the low frequency, the actual experience will still be improved. The best example is Apple's A-series chips, which are not low in peak power consumption, but the A15 has strong peak performance, which greatly increases the energy consumption ratio.
2, heat bearing: no matter how the mobile phone stacks graphite heat dissipation stickers, VC heat equalizer plate and other heat dissipation components, heat can only be passively dissipated through the outer surface of the mobile phone, and can only continue to improve by increasing the surface area, increasing the fan and other methods. The translation is that no matter how good the passive heat dissipation of the mobile phone is, it can only improve the performance output for a short time, and the heat load that the normal mobile phone can maintain is only 6W or so.
The CPU performance of the Snapdragon 8 Gen 1 and the Snapdragon 888 have not substantially improved. In addition, it should be noted that the X1 core of the Snapdragon 888 is 2.8GHz, while the X2 large core of the Snapdragon 8 Gen 1 is 3.0GHz, and the performance at the same frequency is even reversed. Power consumption increases, performance does not increase, energy efficiency compared to the daily effect?
There are two options in front of manufacturers: let go of the Snapdragon 8 Gen 1 run, battery life and heat involvement. Or control the frequency to preserve battery life and heat. Judging from the results, all manufacturers have chosen the latter. As a result, the new Snapdragon 8 can only be fully fired in a very few running applications such as GeekBench, GFXBench, and 3DMakr.
Starting from the Snapdragon 845 in 2018, the highest frequency of Android's flagship SoC will only appear in heavy load scenarios such as application opening and information loading, and some Snapdragon 888 models will adopt global frequency reduction scheduling in the summer of 2021, and the maximum frequency cannot be called when the application is opened. To the Snapdragon 8 Gen 1 generation, in addition to game phones and motos, no domestic manufacturers dare to open the highest frequency in daily life. This is the direct reason why the daily fluency of the Snapdragon 8 Gen 1 flagship cannot win the Snapdragon 888 (even the Redmi K50 Pro of the Tianji 9000 has to open the performance mode to rush to the highest frequency, and the daily fluency cannot be separated from the Tianji 8100 mentioned below)
The huge difference between running score performance and daily performance has made the problem of "running point cheating" more obvious this year. The running score whitelist is a setting that has existed for many years, and Luo Yonghao in the hammer mobile phone period has bombarded the running score whitelist problem of the Android platform: the mobile phone encounters the running score software to run wildly, and the daily use is downscaled.
But this year's Snapdragon 8 Gen 1 in the running score and daily scheduling of the gap is indeed unprecedented, further promoting the "running score useless theory", impacting the trust base of the running score tool: the running score is so high, is not still a card?
Samsung was removed from GeekBench for cheating on running scores
But the running score platform is the most anxious one, the famous running platform GeekBench has been denouncing the operation of the running score whitelist for many years, Samsung, Huawei, OnePlus, and Xiaomi are all regular customers who have been shelled.
Rice evaluation data
So how much performance does the Snapdragon 8 Gen 1 have under daily scheduling? By modifying the APK package name of the running score tool, GeekBench disguised as an ordinary application to bypass the system whitelist, the result is that in addition to the previously delisted Samsung S22 series, Xiaomi, iQOO, True Me, OnePlus and series have obvious performance degradation.
The most conservative Xiaomi Mi 12 Pro, the multi-core score dropped by 12%, which is the early Snapdragon 865 level (yes, Android CPU performance rose 12% in 2 years, and can only be in the running score whitelist); the single-core score fell by 35%, lower than the mid-range Snapdragon 778G. Lu Weibing said at the K50 e-sports edition conference that the stem of "breaking the chip" is also related to strict temperature control and frequency regulation to a certain extent.
However, the heat returns to heat, it must be admitted that the GPU performance of snapdragon 8 Gen 1 has improved tremendously, soaring by more than 50%, and its GPU energy consumption ratio is still higher than that of Snapdragon 888. In the past two years, whether it is Qualcomm's Adreno, or Samsung, MediaTek and other GPUs that use arm public Mali architecture, there have been huge performance improvements. For example, the GPU of the Snapdragon 888 was increased by 35%, and then the GPU of the Snapdragon 8 Gen 1 was increased by another 50%, which chased back the gap that was opened by apple A13/A14 in the previous two years.
But unfortunately, the mobile platform has not yet been able to fully utilize the performance of this batch of GPU performance of important applications have emerged, the bottleneck of mainstream games such as "Original God" has always been on the CPU, and the performance of mobile GPUs continues to overflow. The growth of GPU size makes the power consumption of low loads still considerable. In the case that the fuselage can only carry 6W power consumption, the situation of GPU and GPU "grabbing power consumption" is very obvious, which aggravates the frequency reduction of the CPU.
In the face of enthusiastic chips, mobile phone manufacturers have invariably made consistent "joint optimization": brightness reduction, frame locking, and resolution reduction. Moreover, these three axes also spread from "Original God" to "Glory of kings" and "Peace Elite", which are not high loads, so that this is a "grand situation" that has never appeared in history.
In the past, there was also a setting to reduce the rendering resolution of the game (a GPU Tubro), and the manufacturer could get a straight game frame rate curve at the conference, and could effectively reduce the heat of the game. Red Devil and Black Shark's Snapdragon 8 Gen 1 game flagship can also "frame" the frame rate curve of perfdog, making it a real straight line, so that the test tool loses the effect of detecting the actual frame rate.
But the cost of reducing the resolution is also obvious, as the name suggests, that is, the picture is paste. But the tragic reality is that after the manufacturer's late OTA or user cracked the screen restrictions, it was found that the game experience of the Snapdragon 8 Gen 1 flagship still could not win the Snapdragon 865 22 years ago (analogy: I don't understand why some parents will support banning online games, so that others won't find out that your child is actually stupid).
The current situation of the Android camp: the good news is that the Snapdragon 865 can still fight again, and the bad news is that the Snapdragon 865 can fight again. Formed the "Snapdragon 870 upside down Snapdragon 888, and Snapdragon 888 in turn hung Snapdragon 8 Gen 1" spectacle.
MediaTek also appeared upside down: the Tianji 8100, which was just released in March 22, used the older generation of TSMC 5nm and the older generation of A78 architecture, showing the strongest energy consumption ratio in history, and in large-scale game tests such as "Original God", it personally defeated the Tianji 9000 and became the "annual" flagship in the physical sense. Tianji 8100: Qualcomm 870! Accept my challenge! Then the Snapdragon 8 Gen 1 and the Tianji 9000 fell down.

Samsung process and ARM new architecture
The "Strong and the Powerful"
The reason for the enthusiasm of the two generations of Snapdragon, the first thing everyone suspects is Samsung's 5nm and 4nm process. In addition to the OEM Snapdragon 888 and Snapdragon 8 Gen 1, Samsung also made the same "hot" Exynos 2100/2200 with the same process, and OEM for Google's self-developed Tensor (the only SoC equipped with a dual X1 supercore). In addition to similar processes and architectures, "passion" is their biggest common denominator.
The transistor density of semiconductors is an important indicator to measure the advanced degree of technology. In the same case, the more advanced the process, the lower the heat generation. The chip can output stronger performance with the same power consumption, or achieve the same performance with lower power consumption.
According to The Wikichip data, the transistor density of Samsung's 5nm process node is only 126.7MTr/mm2, and the 4nm LPE is 145.8MTr/mm2. However, TSMC's previous generation of 5nm process already has 171.3MTr/mm2, and even TSMC's N7P process has 113.9MTr/mm2. In terms of process numbers, everyone is going hand in hand, but the actual transistor density has a generation difference of 1 to 2 generations.
If it was only the drag of the process, the Snapdragon 8 Gen 1 might not be so miserable. This year's situation is the result of the "strong combination" of Samsung's process and ARM's new architecture.
This year the Android camp encountered ARM's first major instruction set update, Armv9, a decade after arm launching amrv8. Snapdragon 8 Gen 1, Tianji 9000, Exynos 2200 three major products have been replaced by X2 + A710 + A510 architecture. In addition to the performance of the super core X2 standing still, the energy consumption ratio of the large core A710 has also decreased significantly, and the A510 small core that should be improved the energy consumption ratio is only the energy consumption curve of the previous generation A55 small core, which is stronger in performance but also has a larger power consumption, resulting in the low load power consumption of the chip also rising.
The architecture upgrade actually led to a regression in actual performance, which happened once 7 years ago. It was the distant year of 2015. That year, the name "Fire Dragon" still belonged to Snapdragon 810.
At that time, Apple unexpectedly released its first 64-bit mobile processor, the Apple A7, in 2013. The following year, 20nm, High General Motors "forced" ARM's first 64-bit architecture A57 on the Snapdragon 810. The latter things everyone knows, Snapdragon 808 was forced to become an "agent flagship", mainstream manufacturers skipped Snapdragon 810, resulting in the disconnection of some domestic flagships that year. That year was also the only year for Samsung, which did not use both Snapdragon and its own Exynos chip, and the Galaxy S6 series and Galaxy Note5 that year only had the Exynos 7420 version.
To make matters worse, the X2 and A510 in the armv9 architecture no longer support 32-bit APP, and a large number of backward APP that "insists" on 32 bits in China can only run on 3 A710 large cores, resulting in the embarrassment of "3 cores are difficult and 5 cores are watching". The A710 large core pulls up the voltage of the CPU, resulting in low performance but low power consumption.
The Mobile Intelligent Terminal Ecosystem Alliance was announced on April 6
There are still a large number of 32-bit APP in China, and even some of the self-contained APP in the domestic mobile phone system are still 32-bit. Three months after the release of Snapdragon 8 Gen 1, OPPO, vivo, Xiaomi, App Bao and Baidu finally announced in April that they would no longer be allowed to list 32-bit apps alone, which was a root cause to promote the 64-bit of domestic apps.
In contrast, Apple's iOS required any app update in the App Store to include a 64-bit version in 2015, and by 2017 iOS 11 had forcibly disabled 32-bit apps. Looking back, ARM deliberately retained the support of 32-bit APP on the A710 for the sake of China's national conditions, and I really don't know whether it is a good thing or a bad thing.
In addition, in addition to the ARM company's episode, Nvidia reached an agreement with SoftBank to acquire ARM in September 2020, announced the acquisition failure in February 2022, and then SoftBank announced that it would promote arm listing in 2023. The "coincidence" of time makes everyone laugh at the fact that ARM's new architecture is not good, because "ARM is busy being acquired and has no intention of engaging in architecture", but the prospect of ARM's public architecture is more worrying. ARM prepares for IPO layoffs of 12%-15% globally, and the CPU architecture is thrown farther and farther away by Apple, which is an internal worry. The external problem is naturally the "defection" of the partner.
In the 2 years since Apple's all-platform shift to the ARM platform, M1, M1 Pro, M1 Max, and M1 Ultra have taken turns to refresh everyone's understanding of the ARM camp. This is in stark contrast to the decline of ARM's official architecture and proves that the ARM instruction set can also be used as a high-performance product. In fact, Qualcomm is not bent on "squeezing toothpaste", Qualcomm acquired chip design company Nuvia for $1.4 billion in January 2021, which was founded by three chip experts who left Apple. Among them, Gerard Williams presided over the design of Apple's A13 and previous CPUs, and may also have been involved in the design of the A14 and M1 series chips. Therefore, the outside world is widely speculated that Qualcomm will return to the fully self-developed architecture.
PS: Qualcomm Snapdragon began to develop its own architecture in 2007, and in 2016, the Snapdragon 835 abandoned its self-developed architecture and began to make magic changes based on the ARM public architecture. Samsung Exynos began to use the self-developed mongoose large-core architecture in the 2016 Exynos 8890, insisting on the Exynos 990 (the fifth generation of the mongoose M5) in 2020, and returning to the ARMS public version in 2021.

The importance of SoCs has never been more prominent
Before 2017, the biggest advantage of the domestic flagship is the conscience top + Snapdragon chip. In the past two years, the biggest regret of the domestic flagship has become a chip. A phone with a good chip is not necessarily good, but a phone with a poor chip is absolutely bad. No matter how strong your screen, battery life, charging, and camera peripheral stacking configuration is, as long as the chip is poor, it is a short board in the leaking barrel.
Never before has the general public experienced the importance of SoC chips to mobile phones. Everyone is used to SoCs that will continue to improve (at least not to go backwards). As netizens said: The Snapdragon 835 in 2017 will be sprayed uselessly on the Internet by people who buy mobile phones according to the processor. And in 2022, everyone will buy mobile phones according to the processor model.
Andy Bill's Law never fails, and the performance provided by new chips is eaten up by new software. Even in the past two years, the CPU performance of the Android platform has stagnated, or even regressed, the domestic software has never stopped "moving forward". QQ has built-in Unreal Engine to become a real "domestic AAA masterpiece", and WeChat and Taobao have never stopped adding "fun" functions. What is more tragic than "the old flagship is slower because of the new version of the APP" is that "the fluency of the new flagship cannot win the old flagship".

Unfortunate, but not entirely unfortunate, Huawei
"When Apple puts 2 M1 Maxes together and gives A13s on the display, Huawei can only find the wafers cut 1 and a half years ago from the warehouse, and shield them one at a time to survive."
Huawei was affected by the ban, and the Kirin 9000 became a singing, which is unfortunate, but this timing is a blessing in misfortune. Huawei met the "lost 2 years" of the Android camp: the Kirin 9000 used a very competitive A77 architecture, followed by the X1 used by the Snapdragon 888 and the A78 architecture used for squeezing toothpaste, and a year later was the X2+A710+A510 on the Snapdragon 8 Gen 1.
And The Android 10 when Hongmeng started was also the generation before the bottleneck. Subsequent Android 11 and Android 12, other domestic systems have suffered a lot. In stark contrast to Huawei's luck, Meizu: MediaTek met the best Meizu, and Meizu missed the best MediaTek.
Zooming in to the industry level, 2020 to 2022 is a key time for domestic flagships to rush to the high end. In the 2 years since Huawei gave up high-end space, the domestic flagship has made great progress, everyone has used a 2K screen, charged to kill Apple and Samsung in multiple seconds, the domestic system is white, and even the camera level has not put the iPhone in the eye (of course, the video is still the strongest iPhone). It can be said that domestic manufacturers have prepared everything they can grasp, but the result is that they have encountered the Snapdragon 888 in 2021 and the Snapdragon 8 Gen 1 in this year.
What we see is that HiSilicon was "retreated by the rapids" at the most beautiful time, and the Hiserbeth in our hearts is only a pity, but it is not pitiful. So that netizens ridiculed "Qualcomm this company can be, Qilin was sanctioned it is really going to wait, but also really will encourage Fa Ge to become stronger", everyone also thinks that Qualcomm is helping Huawei drag other Android manufacturers. While Apple watched the Android camp fight, Cook tearfully harvested the high-end market.
Counterpoint data
In the domestic market where Samsung has become a decoration, only Apple has a physical opponent, and other brands cannot catch the high-end market released by Huawei, which is a shame worth remembering Chinese: in 2021, the proportion of China's high-end mobile phones (priced at $600 >) fell from 44.6% in 2020 to 36.5%, and all Androids combined could not win the iPhone. As of April 6, as the façade of this batch of domestic flagships, the first monthly sales of the Xiaomi 12 series were 41% of the previous generation. There is the impact of the epidemic here, but how much responsibility does the chip have to bear? It's up to everyone to judge for themselves.
It is also ironic that the glory of Huawei's previous channels has risen at a very high speed. From honor 50 to honor 60, from magic3 to magic4, product power can perceive that glory has been delayed for more than half a year. But like other flagships, the glory of using Snapdragon chips proves to us with sales that simple product power is actually quite powerless in the face of absolute channel power. Such a fact is not a loud slap in the face of the product manager. Yu Chengdong said that Huawei will return strongly next year, and we are also very curious, what kind of identity will the glory of that time appear?
Every few years, the mobile phone market will have the saying that "Jiang Lang is exhausted and has seen the ceiling". The Xiaomi MIX in 2017 opened the era of full screen and continued to live for smart phones for 2 years; the outsole sensor and telephoto lens arms race brought by Huawei provided a 3-year development period for domestic flagships.
The current mobile phone market is as dazed as the domestic A-share market, and everyone cannot see the future road. A share only has two directions up and down, and should always see the bottom, but domestic mobile phones are more and more confused. Almost exhausted design, screens that have entered the bottleneck period, charging and taking pictures, and SoCs that are not controlled by domestic manufacturers are all reminding us that mobile phone manufacturers do not seem to have found the next development direction. But at this moment, the only thing that can be determined is that the next outlet is not a folding screen.
END
