The folding screen mobile phone has been scolded again. Why can’t it be sold well?

Smart phone innovation is weak, and we once regarded folding screen mobile phone as a new breakthrough.

From Samsung’s Galaxy Fold to Huawei’s Mate X, as well as Motorola’s Razr, the folding screen mobile phone has gradually become a topic raised by major mobile phone manufacturers last year, and even revived the clamshell design that has been silent for many years.

They are as radical as the outside world thinks, using a touch screen that can be folded or unfolded, so that the mobile phone can be turned into a flat plate while taking into account the original size, or the volume can be further reduced by using a folding structure.

However, looking back a year later, these mobile phones, which were claimed to be the future, failed to leave any deep impression on the mass users.

Not only because of the high pricing and low output, the folding screen mobile phone is destined to become a plaything for niche users, but more importantly, people have found many hidden dangers after using the real machine, which also makes the current folding screen mobile phone like a product of trial and error.

Razr released by Motorola at the end of last year also failed to escape the fate of being spit out. This folding screen phone basically retains the design language of Razr V3, such as the classic small chin and flip shape, but it uses a foldable screen inside, which shows a unique retro feeling.

The unique shape has also won a lot of praise from Motorola Razr. Many digital enthusiasts think that it is the best folding screen at present, and the flip shape can further reduce the size of the mobile phone, which is more acceptable to the public than Samsung Huawei’s idea of "turning the mobile phone into a tablet".

Nevertheless, after the aircraft was put on the market, some foreign scientific and technological media gave mixed comments on it.

Among them, the author of Android Central said that although Razr has an amazing design, there is a certain compromise in durability and configuration. For example, after several days of use, the hinge of the machine will make a harsh "squeaking" sound every time it is opened and closed, which sounds very uncomfortable.

In addition, due to its small size, Razr’s experience in battery life and taking photos has not reached the flagship level. Considering its price of $1,500, people should ask for more, but it is obviously untenable to rely on a foldable screen.

▲ Under CNET’s turnover machine, Razr only persisted for more than 20,000 times before it broke down.

In addition, CNET used a self-made machine to flip Razr. As a result, after 27,000 consecutive flips, Razr had a hinge failure and could not close the screen normally. If it is calculated according to the average frequency of users unlocking their mobile phones every day, then a Razr mobile phone will be "broken" in just one year.

In fact, CNET used the same tool to test the Samsung Galaxy Fold before, and the machine insisted on 120,000 consecutive folds.

▲ Motorola’s official testing methods are obviously more moderate.

However, Motorola officials do not agree with this result. They said that CNET’s testing method can’t restore the situation of daily use well, but will further accelerate the wear and tear of parts.

Later, Motorola also released a video showing the correct testing methods, hoping to prove that the machine did not "lie" in its service life.

▲ There are many Motorola Razr that have been "played badly" in offline stores abroad.

The worst is yet to come. With the official listing of Razr, many damaged Razr display machines have appeared in major offline stores abroad. For example, Max Weinbach, the author of XDA website, saw a prototype whose screen was stripped off, which was obviously caused by human factors, but it also proved the fragility of the folding screen mobile phone from the side.

Some people also found green stripes on the store trial machine, or encountered the situation that the half screen continued to flicker, which was very similar to the problems encountered by the first batch of Samsung Galaxy Fold. The high probability was the failure of the display screen caused by frequent folding.

In any case, in this new product of Motorola, we still don’t see the possibility of mass production of folding screen mobile phones, but it will further dispel users’ desire to buy.

From the design point of view, there have been several forms of folding screen mobile phones, but at present there is no solution that can completely solve all the hidden dangers.

One is the durability problem, which is also the biggest obstacle for folding screen mobile phones to enter the mainstream market. Although several manufacturers claim that their products can withstand 100,000-200,000 times of opening and closing, screen folding is only one of the scenes in actual use, and people have to consider many factors such as falling resistance, scratch resistance, dustproof and waterproof.

▲ The difference between eversion and eversion structures also leads to different design choices.

The structural differences between eversion and eversion will also lead to different design choices. For example, Samsung Galaxy Fold uses two screens inside and outside, which can really protect the inner screen better. Although Huawei Mate X’s eversion design can balance the thickness and size, the screen is exposed all the year round, and it is difficult to avoid scratches.

On the other hand, because the folding screen mobile phone often adopts the structure of left and right or up and down, it also means that it is difficult to reuse the existing component layout of traditional mobile phones.

▲ Dual battery layout in Samsung Galaxy Fold fuselage

For example, at present, Samsung, Huawei and Motorola basically choose the "double battery power supply" scheme for folding screens. In fact, one battery is placed in the left and right or upper and lower parts of the folding screen mobile phone.

Due to the large size of Samsung and Huawei, the actual battery capacity of both exceeds 4000 mAh, while the small size design like Motorola can only guarantee 2500 mAh battery, and the battery life will naturally decline.

▲ Motorola Razr uses two dynamic brackets at the rotating shaft.

Hinge is also a technology that folding screen mobile phones have to ignore. When the screen is frequently folded and squeezed, it is not only the screen that is lost, but also the life of the mechanical hinge.

At present, Samsung and Huawei have adopted different hinge schemes for folding screen mobile phones, and the gap after folding can be controlled in a small range, but the disadvantage is that users have to use both hands to unfold the mobile phone into a flat state.

At this point, the design of Motorola Razr’s upper and lower flip covers is more humanized. With the help of the hollowed-out part left by the dynamic bracket, Razr solves the crease problem caused by the folding screen under large curvature, and the compact size also allows the user to open/close the flip cover with only one hand.

However, the new design also brings new problems. Because of the hollowing out, Razr’s screen is not closely attached to the mobile phone. The BBC showed a detail in the hands-on video, saying that users can easily lift the screen layer of Razr with only one nail hook. At this time, the internal components are completely open to the outside world, which will undoubtedly become the "hardest hit" for all kinds of dust and debris.

One of the reasons why mass consumers are not interested in folding screen mobile phones is the price. Judging from several folding screen mobile phones currently on sale, their official pricing has exceeded 10,000 yuan, which is much more expensive than many mobile phones with the same flagship positioning.

Considering the low yield of folding screen mobile phones and the need to redesign related components, it is understandable to set the price higher. However, if this is just a screen, it is obviously more harmful than good to sacrifice the original experience such as durability and thickness.

This is also why only a few manufacturers have decided to mass-produce folding screen mobile phones, while some other brands have also shown prototypes, but they have no plans to mass-produce them.

For example, Xiaomi’s MIX Alpha, although this product does not have a "folding" part, but it uses a large bending screen structure, it also needs to use similar technologies as folding screens.

In the original plan, Xiaomi MIX Alpha should have had a small-scale mass production at the end of December last year, but now there is no following. Until today, this mobile phone can only be packaged in the glass cabinet of Xiaomi House, and perhaps even Xiaomi himself is not at ease to hand over such a concept device to consumers.

Walking into 2020, the folding screen mobile phone is about to usher in its first iteration.

The fastest progress should still be Samsung. At today’s Oscar film awards ceremony, Samsung has announced a new generation of folding screen mobile phone Galaxy Z Filp in advance through TV advertisements.

Different from last year’s Fold, this time Samsung chose a clamshell design similar to Motorola Razr, which should get a better experience in a thinner volume.

At the same time, there are some rumors about the upgraded version of Huawei Mate X. It is reported that the aircraft will be equipped with a new Kirin 990 chip, but it will continue the everted structure.

Earlier, Gao Dongzhen, president of Samsung Mobile, also revealed in an interview with the media that the sales volume of Samsung Galaxy Fold should be around 400,000-500,000 units, while Huawei Mate X, which is only sold in China, shipped around 100,000 units in the first month after its launch.

There is no doubt that in the face of current pricing and product maturity, Samsung and Huawei will obviously not hold the sales target of millions of orders to produce folding screen mobile phones. At least until the hidden problems mentioned above are solved, the traditional flat mobile phone will still occupy the main position.

This is the same as the curved screen mobile phone of that year. If the folding screen mobile phone wants to become a new star product, it still needs to wait for the gradual iteration of screen and hinge technology and the cost reduction of the upstream supply chain when it develops to a more mature stage.

A similar development path can refer to Samsung’s curved screen technology. Although as early as 2013, Samsung has released the first mobile phone Galaxy Round with curved screen design, at this time, Samsung’s flagship is still a flat screen mobile phone.

It was not until the Galaxy S8 series in 2017 that Samsung really let the flat screen completely withdraw from the flagship camp and fully applied the dual curved surface screen to its flagship machine. In the past two years, with the decline of cost, Samsung is not the only mobile phone with curved screen design.

However, what is certain is that the folding screen will definitely not become a short-lived design like the lifting camera. After all, technology suppliers such as Samsung obviously value not only the category of smart phones, but the folding screen technology itself.

As the carrier of information, people are still obsessed with making the screen as thin as paper, and it can be rolled up and taken away like files and newspapers, which makes "folding" an inevitable stage in the development of screen technology.

Therefore, even if the folding screen mobile phone cannot become a decent business, the research and development related to folding screen will continue to progress.

As long as the material and structure constraints can be solved, the future display screen will not only appear on electronic products, but also be further extended to the surfaces of various objects, which is suitable for more equipment and scenes.

Combined with the predictions of many British media, leicester city’s relegation probability is above 55% on average.

Combined with the predictions of many British media, leicester city’s relegation probability is above 55% on average. Followed by Leeds, with an average of 47%, Nottingham with 40% and Everton with an average of 35%.

There are still two games left in the Premier League, and the biggest topic is Manchester City’s reversal of victory over Arsenal and who will fill the second place in the relegation of the British Championship.
Southampton failed to avoid relegation, but the 19th leicester city (30 points), 18th Leeds United (31 points), 17th Everton (32 points) and 16th Nottingham Forest (34 points) were fiercely competitive. on going
Combined with the predictions of many British media, leicester city’s relegation probability is above 55% on average. Followed by Leeds, with an average of 47%, Nottingham with 40% and Everton with an average of 35%.
The remaining two games are more complicated. Leicester will go to Newcastle United to compete for the third and fourth place, so as to secure tickets for the UEFA Champions League (UCL) next season. Their last opponent is West Ham United at home.
Leeds United’s appearance order is West Ham United (away)-Tottenham Hotspur (home). If West Ham draw with Leeds United, they will be confirmed to stay. Even if they emerge from the UECL semi-final, the league is different. Tottenham Hotspur need to catch up with Leeds United to save the Champions League. Leicester and Leeds are almost as anchored as West Ham.
Everton’s order is wolverhampton wanderers (away)-AFC Bournemouth (home), and the latter confirmed their accommodation. That’s why Everton has a higher chance of staying in the team, because the pressure on the other team is less. Nottingham’s ranking order is Arsenal (home)-Crystal Palace (away). Arsenal lost the title race. With one game less, Manchester City still topped the list with a 4-point lead.
Manchester City will play in the order of Chelsea (home)-Brighton Hof (away)-brentford (away). Beating Chelsea is guaranteed. Arsenal should want Manchester City to lose to Chelsea. We must seize Nottingham and wolverhampton wanderers at the same time with the hearts of thousands of people. Of course, Manchester City’s victory is certain. Arsenal played Nottingham first, then Manchester City played Chelsea. This is a big disadvantage. Arsenal are strengthening ties with the players who are behind in the championship competition. The attack team included Leandro Trossat, Gabriel Martin Nelli, Gabriel Jeju, Eddie Nkitiya, Bukayo Saka and Martin Edgor, but they concluded that they lacked.
In the case of entering many reinforcement candidates, it is natural to pick up the ears in the teams that have been relegated. Leeds often mentioned Rodrigo Moreno and Patrick Buckford. According to reports, Arsenal put Snake Ford in sight.
Bamford is a resilient and fast striker. He signed a contract with Leeds until June 2026, but if he falls into the mire of relegation, he may move. Of course, I remember winning in Leeds, so it is possible to maintain my sanity, but even if it is not Arsenal, Aston Villa and other upper-middle-class teams, the temptation is great.
In Southampton, which ranked last, midfielder James Ward Fraus is rapidly becoming a transfer target. Ward Fraus also wants to move, so his value will go up. It is said that Bamford’s worth has reached 20 million pounds (about 33.2 billion won).
Rodrigo’s contract will end in June next year. Liz’s position is that as long as it exceeds 10 million pounds (about 16.6 billion won). It is said that Aston Villa Unai emeri is what she wants. If Li Kangren (Mallorca) is held in emeri’s arms, Rodrigova will finish the story of "reunion" after Valencia.
Everything depends on Liz’s choice. However, if you stay away from relegation, the situation will change 180 degrees.

What is the difference between a steam room and a sauna?

I always can’t tell the difference between sweat steaming and sauna, I don’t think there is any difference between the two, so what is the difference between sweat steaming and sauna? Which is better, steam or sauna?
First, the principle is different
Sweat steaming mainly uses the energy field formed by the negative ions, far-infrared rays, and micro-currents released by tourmaline to act on the human body and stimulate the body to generate heat energy; while sauna uses high-temperature water vapor to act on the skin from the outside and conduct heat into the body. .

Second, the temperature is different
The steaming temperature is around 42-45 degrees Celsius, and the scientific steaming time is 40-60 minutes. People will not feel suffocated during the sweating process, and the breathing will be very smooth; the sauna temperature can reach 60-70 degrees Celsius, when the human body can only stay 5-10 minutes, if the time is too long, you will feel chest tightness and shortness of breath.

  1. Perspiration effect
    The sweat discharged by the steaming has no sweat smell, which will make the human skin smooth, which can have the benefits of beauty, body beauty, and disease conditioning. However, it should be noted that it is not suitable to shower within 6 hours after the steaming, as the shower will detract from the health care of the steaming. The sweat is sticky and has a smell of sweat, and it is necessary to take a bath after the sauna to remove the smell of sweat.
  2. Operation method
    Sweat steaming is through physical conditions such as far infrared rays, negative ions, expanding substances and trace elements to expand the pores of the human body in a high temperature manner, discharge toxic substances in the body, and achieve the effect of health care; while the sauna uses steam to make the deep skin heat effect under high temperature conditions. , and then achieve the effect of expelling toxins in the body through the pores that are enlarged under high temperature.
