Mobile phone manufacturers are vigorously building a software ecosystem.

htmlOn November 8, the domestic mobile phone brand Vivo officially launched OriginOS 3.0 at the developer conference. The new system emphasizes "smooth and silky", bringing users a smoother user experience. Strictly speaking, OriginOS is a user operation interface customized by vivo based on Android, and cannot be considered an operating system, but it is obvious that vivo will invest more in the operating system next.

software team has 3,000 people to alleviate the phenomenon of "killing the backend"

vivo has been launching OriginOS for three years. The original intention of the design is to hope that users will feel "simple and easy to use". In 2021, a series of new functions including lock screen, atomic components, and atomic notifications will be launched.

vivo Vice President and Vice President of OS Products Zhou Xiang said in an interview with Pengpai News reporter that vivo has 3,000 software team, of which more than 1,000 people have artificial intelligence team. Through almost two years of research, this time, OriginOS 3 brought the first underlying breakthrough in technology, changing Linux's fair scheduling to unfair scheduling, which absolutely prioritized the process of users being operated and could be comfortable and smooth.

explained around

that OriginOS 3 will bring unprecedented silky, lightweight and lasting smoothness to users. This is not as simple as a slogan. "The entire OS is divided into four layers. The first layer customizes hardware and devices. This requires customized chips to solve. It takes a long cycle, at least 24 months. It is too late for us and will be displayed in the next few years. With the system's hardware resource customization has been fixed, we will solve the problem of smoothness and easy-to-use in the three levels of kernel, framework and application ecosystem."

said that the most technical challenge is the kernel. The Android kernel has been used so far. How to perform optimal system scheduling and resource allocation requires deep customization and optimization of kernels from the three dimensions of computing, storage, and display. "Today, when many mobile phones have abundant hardware resources, there is occasionally lag. This is because Android uses fair scheduling algorithms. For example, 10 million computing applications are applied for resources in the background, and we have to allocate them correspondingly in the cluster." About

, vivo's approach is to give priority to ensuring that the applications and programs that users are using on the mobile phone have sufficient resources guarantee, and then divide some of the resources to the background, and rewrite the fair scheduling algorithm to the unfair scheduling algorithm. The purpose of this is to ensure that the user remains smooth during the use of the foreground application. In addition to the improvements in scheduling algorithms,

also alleviates the phenomenon of "killing the backend" of mobile phones. "Many mobile phones use up the memory of the system after opening 20 applications. If you open another application, the system will recycle the application (kill the background). It takes a certain amount of time to start it again. We call it cold start, and this experience is not smooth. In software engineering and kernel, we call the on-site record 'Tombstone', which is literally translated into Chinese as tombstone. We named this innovation as 'resurrection in place', which greatly reduces the time for some applications to start again, and at the same time return to the interface that the user used last time. We hope to use this innovation to OriginOS 3 lets everyone feel a more coherent and smooth feeling. "

" Ecology is a real obstacle to the operating system"

" Currently, China has two ideas in operating system solutions. One is a complete operating system solution represented by Hongmeng , which is a complete operating system solution from ecology to kernel to framework; there is another project under the Open Source Foundation, whose name is Quick Application (a new application ecosystem jointly launched by nine major mobile phone manufacturers based on hardware platforms. Users do not need to download and install applications, but click and use them immediately and enjoy the performance experience of native applications). "The surroundings indicate that vivo has chosen the second path.

public information shows that in 2020, China established the Open Atom Open Source Foundation (Open Source Foundation). The service scope of the Open Source Foundation includes open source software, open source hardware, open source chips and open source content. He is also one of the directors of this foundation.

explained around

that the operating system is currently divided into at least three layers. The first layer is the kernel. Now there are no obstacles in the solution path of the Chinese operating system in the kernel. Currently, vivo, Xiaomi , OPPO, Huawei also have kernels; the second layer is the framework, the language, compilation, linking, and debugging environment of the operating system. Each company has its own implementation plan in this direction; the third is the ecology, and the ecology is also a real obstacle to the operating system, and the operating system needs to have a truly self-contained ecosystem.

"For example, like Android, there are more than 4.6 million application ecosystems in the entire industry. What is difficult to break through is platform-level ecological application. This ecosystem is difficult to break through. If the ecology is solved, plus its own frameworks and tools, plus the combination of the underlying kernel, it is a complete operating system solution." The surroundings said that everyone is familiar with Hongmeng's path at present, but the discussion of the second path is not that sufficient.

also revealed around

that vivo is pre-researching its own commercial operating system. "I hope this operating system will meet with the public with a mature commercial and application ecosystem in the coming year."

Now smartphones are facing innovation bottlenecks, and manufacturers can improve the overall user experience through software optimization and ecological services. Secondly, software and ecological strategies can also bring some additional revenue to the company. In this regard, Apple has always had a very good balance between hardware and software.

However, the surrounding area said that vivo's OS ecosystem is not viewed from the perspective of business operations, but from the trend of users. "For example, the trend of business and office. Now large screens and folding machines are more popular. So in the past two years, we have always hoped to create a better and complete office and business solution for everyone. We have supported more than 150 commercial companies at the same time, so that their office environment should have a better office experience on our mobile phones." Shi Yujian, senior vice president of

Vivo, also said at this developer conference that vivo mobile phones have now entered more than 60 countries, with a total global user base of more than 400 million, and a total overseas user base of 160 million.
