Original title: Foreign media: The new version of Samsung Galaxy Fold is damaged after one day of use.

  

  Webmaster’s House (ChinaZ.com) September 27th news: Samsung’s folding mobile phone Galaxy Fold was expected to be released earlier this year, but Samsung recalled this mobile phone due to display problems, and it was officially listed in South Korea on September 6th after solving the problems.

  This Friday, Samsung Galaxy Fold will be released in the United States tomorrow, but according to TechCrunch editor Brian Heater’s report, it has been using the Galaxy Fold for about one day, and the screen is damaged again. In the middle of the damaged screen, there are bad spots like stamens, which are very dense.

  It is said that during the 27 hours of using this Galaxy Fold, Heater did not fall or fall into the water, and it was completely used routinely. It is speculated that the damage of the mobile phone may be caused in the process of closing/folding the mobile phone. Although the size of the damage is less than one centimeter, it is impossible to imagine how serious the damage will be with the passage of time.

  Note: The picture is from TechCrunch screenshot.

  Although Samsung has publicly reminded users to "don’t put pressure on the phone", "touch it as lightly as possible" and "don’t put anything on the screen before folding the screen" when using this phone. Heater said that he did not appeal.

  It is worth mentioning that Samsung has launched a service, including the replacement of the screen for $149. Officials have said that Galaxy Fold is the first folding mobile phone, which is made by new materials and technologies. Users are encouraged to use it according to the product manual. If you have any questions, you can consult Samsung officials.

  It remains to be seen whether the damage to the Galaxy Fold screen of Heater is covered by the warranty. Or users can buy a $149 service to replace the screen in case it is damaged.

  Weifeng. com will broadcast the Apple conference live on micro-headlines, so stay tuned.

  On the evening of September 6th, vivo held a launch conference for the new machine in Beijing. As expected, the focus of this conference was the new vivo X23 product. This is a smartphone with mid-range positioning in vivo. It comes standard with Xiaolong 670+8GB+128GB and is priced at 3498 yuan. It features 3D phantom aurora shell, water drop screen +COF chin, dual turbo engine in vivo and super night shooting experience.

  First of all, in terms of design, most domestic mobile phone manufacturers like to make a big fuss about the back case, and the new machine vivo X23 is no exception. This time, the main theme is 3D phantom aurora pattern. According to the official, vivo is made of 3D glass, and tens of thousands of silk patterns are engraved on the diaphragm less than 80cm2, and then polished by unique gas plasma, and finally the "real aurora pattern that can flow between the palms" is spread on the back of vivo X23.

  Vivo X23 offers a variety of color schemes, but it mainly promotes magic night blue and phantom purple, and carries out "chord-moon arc" treatment on the middle frame. Vivo said that X23 embedded a beautiful curved surface between the front screen and the middle frame, thus narrowing the middle frame of 3.2mm to 2.6mm, and the thickness of the whole machine was only 7.54mm, which looked like a curved moon on the side, so it was called "string arc", with good visual and hand feel.

  On the front of the fuselage, vivo X23 also uses a special-shaped full screen, which some domestic manufacturers call "Beauty Tip" and "Pearl Screen", while vivo calls it "Smart Droplet Screen", and compares the groove opening at the top to "a water drop gathered". The size of the whole screen is 6.41 inches, with Super AMOLED panel, resolution of 2340×1080 pixels and screen ratio of 19.5: 9.

  At the same time, in order to get rid of the big chin, vivo also adopted COF technology on X23 to ensure the extremely narrow bottom frame. Simply speaking, COF technology is to integrate the screen IC chip behind the flexible panel. According to vivo, when the user lights up the X23 screen, the visual experience is absolutely unparalleled.

  This screen is also integrated with a major technology, that is, screen fingerprint recognition technology, and the official said that this is a further "fourth generation photoelectric screen fingerprint" technology than vivo NEX. Vivo said that screen fingerprint has always been the traditional strength of vivo. The fourth-generation photoelectric screen fingerprint carried by X23 has a large aperture lens of F/1.5, which ensures more light input, and the pixels per inch that can be captured is increased to 720, which makes the fingerprint imaging clearer. Finally, the speed of unlocking the screen is as fast as 0.35s by combining the new screen fingerprint algorithm. Of course, there is an ultra-super-light-sensitive screen whose thickness is 0.1mm less than that of ordinary OLED screen, which is more conducive to light penetration.

  In addition to the conventional 3D phantom aurora back shell, vivo also provided a version of vivo LOGO PHONE. The official said that combining tradition and modernity, vivo was displayed on the back of the mobile phone as a product design language.

  In terms of hardware configuration, vivo X23 mobile phone is equipped with the latest Qualcomm Xiaolong 670 AIE processor. Compared with the previous generation Snapdragon 660 processor, the CPU computing power is improved by 15%, the GPU image processing power is improved by 25%, the endurance is improved by 12%, and the AI computing performance is improved by 80%. In terms of running memory and storage capacity, X23 comes directly as standard with 8GB of storage +128GB of flash storage. It also provides audio Hi-Fi chip AK4377A, comes as standard with 3400mAh battery, and supports 10V 2.25A half-voltage flash charging scheme.

  In order to ensure the smooth performance, vivo officials said that they not only provided a ten-layer heat dissipation structure with the function of accelerating heat dissipation, such as curable heat-conducting gel, high heat-conducting aluminum alloy frame and multilayer composite graphite heat dissipation film, but also built a vivo Dual Turbo twin-turbo engine that fully stimulated the performance of software and hardware, and spent a long time introducing this engine.

  The dual turbo engine of vivo has two main features. One is that it took two years to modify the real core module of Android by nearly 20%, and the first turbo vivo System Turbo was obtained. With the help of this engine, the fluency of mainstream applications has increased by an astonishing 100%, the anti-frame dropping ability of mainstream games has also increased by 100%, and the anti-slow jamming ability of games under strong stress test has increased by 300%.

  Another turbine engine, vivo, said that it became the first mobile phone manufacturer to cooperate with Unreal Engine unreal engine in China, and joined forces with tencent games Lab and Netease Game Lab to get the second turbine vivo Game turbo, which can schedule resources in advance and give gamers a comfortable competitive experience in all aspects.

  The back of vivo X23 is equipped with a dual camera with 12 million pixels and 13 million pixels. First of all, it focuses on the "powerful night shooting" photo experience, mainly based on the quality of the sensor module itself. Because the main camera of vivo X23 is equipped with a brand-new Sony flagship IMX363 sensor, with a pixel area of 1.4μm and an f/1.8 super-large aperture lens.

  The sub-camera is a 13-megapixel camera with a super wide-angle lens, and its wide-angle field of view reaches 125, which can shoot more pictures than an ordinary camera with a wide-angle field of view of about 80 degrees. In addition to super wide angle, vivo’s excellent backlight technology has also been extended to X23 and upgraded to "super backlight". vivo claims that the revolutionary wide dynamic range of up to 12.3Evs makes the details of bright and dark parts completely preserved.

  Bodybuilding is another main function of vivo X23. Among them, the body camera means that when users are recording videos, the software can help you adjust your body shape, such as long legs, thin waist, thin shoulders, rich buttocks, etc., mainly through AI algorithm, and can also provide different adjustment effects for men and women respectively.

  The front camera of vivo X23 is 12 million pixels, and it is equipped with a fixed-focus lens with an aperture of F2.0. There are two major features of proactive camera. One is the face-rejuvenating camera with AI beauty and AI light effect, which can be adjusted with built-in software for every facial detail. The second is zero light perception face recognition. The ultra-broad spectrum camera can accurately detect and quickly recognize faces in extremely dark environments by using visible light and infrared light, and with the brightening algorithm and noise reduction algorithm, ensuring an excellent face unlocking experience.

  Finally, the price and listing date. The standard version of vivo X23, 8GB+128GB, is priced at 3498 yuan. Online and offline pre-sales have been started simultaneously, and it was officially launched on September 14th. Another version of vivo LOGO PHONE will not be officially launched until October 1.

Recently, a game made by Chinese people called "City of God" landed on Steam Green, and finally won the sixth place. This game focuses on pixel and sandbox crimes. Players can play a warden, run a prison, recruit criminal gangs, engage in street fighting, rob shops, take hostages, sneak into theft, and manufacture and sell drugs.

  

  Video of puzzle playing clip

  Grape Jun contacted Zhang Shen, the producer of "City of God", and he told us about the development origin, gameplay and the process of getting on the Steam green light.

  The origin of development: a long-cherished wish after ups and downs

  In fact, Zhang Shen has been developing games for more than ten years.

  Since 1999, Zhang Shen has worked in Zhiguan and Shanda, and started his own business as a private server and a page tour. In 2013, he felt that the mobile game market was full of gold, so he came out to start a business and made an infringing card-based cottage mobile game. This hand tour has achieved good results, and it is said that there are about 50 million running water throughout the year. At that time, the company once expanded to more than 100 people.

  After that, they added distribution business and set up five products, but they couldn’t make any money. Gradually, the monthly income of their first product is only a few hundred thousand, and the R&D team has become the biggest redundancy. "The gold rush is over, we don’t have core competitiveness, and we have to give away a Ferrari every month …" In desperation, the team began to disband, leaving only a few people.

  In March this year, Zhang Wei went to Japan to visit companies such as Glory and Bandai Nanmeng Palace, and felt their spirit of playing games for decades, and finally realized a problem:

  "I’m not suitable for a speculator, and following the trend can’t give me a sense of security. When the company is big, I feel awkward, but in fact I am not me. "

  As Zhang Wei said, "It’s really inspiring to let go of the company and fame." One day, he saw a police car in the homestay next to Lake Biwa, and suddenly he was inspired. I stayed up all night and wrote a long planning case of "City of God".

  Play: sandbox crime with high degree of freedom

  At first, Zhang Shen’s idea was very huge. The gameplay includes both simulated management, RPG and SLG;; The scene has both a large-scale sandbox city and several detailed room strongholds; Warden, zombies, even a dog will all become the protagonists of the game. "You will gradually learn about the past of every criminal, such as the dog was the son of a scientist before he was assassinated …"

  However, unlike many independent developers who are passionate and want to realize all their ideals with one game, the rationality of controlling products still prevails. "I want to launch a decent version in at least one year. Because of my money, the flowing water of my previous works, plus the financing I got in February, may only be enough for my brothers to spend a year. " So, he is going to split the grand world into three games that are related to each other but play differently.

  The same is true of art and music solutions. "We don’t have the experience and funds to do 3 D. If we don’t do well, we will become a short board; 2D art is not outstanding enough. And pixels neither add points nor subtract points. " In addition, this team of only eight people did not outsource sound effects. Zhang Shen personally composed 16 BGM songs. "I can’t tell my feelings and the outsourcing team can’t understand them, so I’ll do it myself."

  In the first-generation game being produced, namely "City of God: Prison Empire", players have to play the role of the warden who has just taken over a prison. In order to support themselves, they start to build cells, accept criminals, and start processing factories from clothing to drugs and firearms to make profits.

  prison

  With the improvement of the prison level, players will find more criminals with different specialties such as blasting, firearms, driving and stealing. Players can do whatever they like, build functional buildings, and let them drink, gamble and prostitute … Once criminals have trust in players, they can enter the big map, commit crimes for players and generate greater profits.

  Bars, casinos, brothels and so on.

  City of God has a huge sandbox map. "We have designed personality hobbies for each resident; Every car can rob; Players can also change their styles in barbershops and clothing stores. The difference from GTA is that every room in the game can be visited and random levels are generated; Players can also make drugs and even conduct international trade after investing in public facilities. " At the same time, the game may also add social elements of buying and selling resources among players in products such as Hay Day and Sim City.

  Racing, hostage-taking, confrontation with the police, gang fighting, bank robbery and sneaking in correspond to different ways of playing. QTE, team configuration, diving, solving puzzles, etc. will all be added to the criminal process as light gameplay. Zhang Shen is also working hard to make the gameplay have a multiplication effect. "Criminals can be recruited not only through human resources systems and side tasks, but also through framing. For example, if you want to build a drug processing factory, you must first get a scientist. To get a scientist, you need to send criminals into his room, put drugs at home, and frame him for imprisonment. "

  Town map

  As shown in the video at the beginning of the article, City of God already has a Demo that shows how to solve puzzles. In Demo, players have to solve various puzzles, sneak in or even shoot through security guards, steal money and run away in a limited time. Of course, this Demo is a bit stiff because there is no other gameplay and narrative supplement.

  Climb the Steam green light: almost like a dream.

  Zhang Wei said that pixels and crime themes are definitely not very popular in China, and it is even difficult to pass the trial. Therefore, it is almost the only way for them to board the Steam green light in advance and meet the global Steam players as soon as possible.

  The road to green light is not smooth. At first, many foreigners would directly comment: "China game is a cottage game, which is rubbish, so I ordered NO directly!" Some people will compare the game with other products.

  But later, Zhang Shen introduced the game over and over again in SteamCN, forums and post bars, communicated with players, and showed many details of the circle powder:

  Warden! Please ask your purchasing manager to buy shower gel instead of soap. This will greatly reduce the death rate of your prisoners in the bathroom.

  If you want to rob or steal during rush hours, it is recommended to plan ahead. In order to avoid traffic jams during running. …

  Gradually, the interface of "City of God" received more than 700 replies. Many Russians still ask why there is no Russian version. Finally, this game got the sixth place. During the days of voting, the whole team was half asleep: "Is this fucking true?" There are even players from the Foreign Languages Institute of the United States, New Zealand, Canada and China who responded to their call and participated in the English-speaking process of the game without pay.

  Zhang Wei said that at present, the completion progress of "City of God" is about 40%. With the experience of previous projects, the technical difficulty is not great. Prison internal construction, big map and random checkpoint development tools have also been completed. Next March, a complete Demo will be released. In June, E3 will be exhibited, officially released and landed on the Steam platform. Now they have also participated in the PS competition, seeking opportunities to cooperate with Sony and board the mainframe. As for the mobile version, it will be further away.

  In Grape King’s view, the biggest problem of "City of God" lies in the diversity of gameplay and the huge structure. Zhang Shen also admitted that "the team is still doing subtraction to find a balance point that can keep the fun of playing without affecting the overall structure."

  In Zhang Wei’s view, The City of God is not in a hurry. After all, it takes three generations of games to present his plan completely. He said with a smile, it doesn’t matter that the first work was scolded, the second work was scolded, and the third work was scolded.

  "If you do the fourth part, someone will always say yes."
