　　With the opening of HDC2023 developer conference, HarmonyOS 4.0 also surfaced.

　　As the most important part of Huawei's ecosystem, HarmonyOS will bring new capabilities and features to consumers, and also show users the future focus of Huawei's mobile terminals. HarmonyOS 4.0 is no exception.

　　Before HarmonyOS 4.0 was officially released, I had been using the Beta version as a developer for about 2 weeks. Believe me, when you upgrade HarmonyOS 4.0, your first feeling must be the same as mine, that is: fluency.

　　HarmonyOS 4.0 changes in appearance, which is very young. 4.0 The screen lock interface has been redesigned. Now users can identify photo subjects, such as people and pets, through AI matting, and combine more background images to bring users different impressions.

　　In addition to photos, HarmonyOS 4.0 can be arranged in a new Emoji expression combination, turned into wallpaper and off-screen interface, and seamlessly unlocked through smoother transition animation. In addition, HarmonyOS 4.0 is also equipped with a panoramic weather wallpaper, so users only need to look at the weather displayed on the wallpaper to perceive the weather changes in real time.

　　In addition, HarmonyOS 4.0 has also made many optimizations in the details of the system, such as music control center, folding screen opening animation and so on.

　　However, compared with the adjustment on the UI, the functional change of HarmonyOS 4.0 is the highlight of this conference.

　　In HarmonyOS 4.0, four keywords can summarize the main updating directions: information visualization, enhanced information flow, AI big model, and brand-new risk control.

　　Information visualization

　　For mobile phone equipment, how to obtain information more efficiently and intelligently is the ultimate problem that every mobile phone manufacturer is thinking about. HarmonyOS 4.0 provides a new way to solve problems with "live window".

　　The birth of every new function is accompanied by Huawei's thinking and views on this kind of function, which is exactly the case. Huawei puts the "live window" in a corner of the upper left corner of the device. This new function integrates all the advantages of iOS smart island and vivo atomic notification, and will not be limited by the hardware layout of the mobile phone screen.

　　Through the two forms of capsules and cards, users can have a complete and continuous and efficient experience. For example, for take-away applications, the status of "eating, picking up and delivering" can be displayed in real time, avoiding the notification screen, and allowing users to obtain information efficiently and intuitively.

　　On the smart watch side, the crescent moon window designed in combination with the watch shape can surround the check-in counter, take-out process, travel license plate number and other information at the upper right of the dial through a strong reminder, so that users can get important information by raising their hands.

　　Let's take Huawei Mate 40 Pro+ in 4.0.0.108, which has upgraded the latest version of Harmony OS, as an example. When the user chooses to record and hangs it in the background, a "capsule" will appear at the upper left position of the screen to realize the state and time of recording, and after clicking the capsule, it will be enlarged into an operable interactive interface.

　　However, due to the "pill" hole-digging design at the top of Mate 40 Pro series, the position of the live window has been squeezed to some extent. I believe this function will have a more perfect presentation effect on the equipment with a hole-digging center like P60 Pro.

　　Information flow

　　For Huawei, the core of information flow is: where is the attention, where is the service.

　　Therefore, no matter how iterative the circulation function of HarmonyOS is, it will never leave this central direction. At the beginning of the press conference, Mr. Yu announced a brand-new short-range wireless connection technology-NearLink.

　　NearLink integrates the advantages of traditional wireless technologies, such as Bluetooth and Wi-Fi, with a set of standards, and is suitable for various scenarios, such as consumer electronics, smart homes, new energy vehicles, industrial intelligence, etc., to create a lower delay, lower power consumption, wider coverage and safer connection technology for users, and bring innovative experience of HarmonyOS ecology.

　　The function of super transfer station has been loved by many users since it was launched on HarmonyOS 3.0. On HarmonyOS 4.0, it has added practical functions such as file preview and clipboard historical content query to help users collect fragmented information better. Not only mobile phones, but also super transfer stations support tablets and PCs, making cross-device sharing more convenient.

　　Based on the powerful distributed ability of HamonyOS, the content circulation of HarmonyOS smart cockpit has also had a better experience: multi-screen sharing allows passengers in the front and rear rows of the car to watch movies simultaneously; Transfer the game on the mobile phone to the car, and you can play mobile games with the big screen in the car; When operating a drone, you can also use the cockpit screen as a large display screen with the help of the super desktop, and you can easily control the drone by sitting in the car through the cockpit screen.

　　Little art assistant blessed by AI big model

　　As the hottest AI landing project at present, HarmonyOS 4.0 is the first manufacturer to build it into mobile assistants. Huawei's three key words for the new version of Xiaoyi are: smarter, more capable and more caring.

　　Users can communicate with Xiaoyi in a more colloquial way based on their own speaking habits and intuition. Not only that, Xiaoyi can understand the content of the picture and process it, such as recognizing the address on the poster and navigating with one button, and viewing the information on the business card and storing it with one button.

　　Not only that, relying on the multi-modal large model technology, Xiaoyi can also realize the function of "fun pictures" and personalize and stylize the existing images for secondary creation. Xiaoyi is also a smart assistant who knows users better, and can help users record inspiration or important events and provide search and reminder functions. Xiaoyi suggestion upgraded the scene combination card function, which can perceive more high-frequency scenes of users and actively generate different xiaoyi suggestion cards.

　　P.S.' s small art assistant based on the big model will be open for testing in the second half of August, and interested friends may wish to continue to pay attention.

　　Risk control ability

　　Huawei has always attached equal importance to privacy to Apple. HarmonyOS 4.0 makes risk warning more visible and risk application more controllable through a series of security functions such as brand-new application control center and application tracking management.

　　On HarmonyOS 4.0, Huawei has also brought security protection for children, including pure and undisturbed, game anti-addiction, payment behavior control and application content grading, to create a healthy computer environment for children. And parents can also help their children use electronic products more reasonably through the remote guardian function.

　　HarmonyOS 4.0 early adopter test

　　At present, Huawei has opened the early adopter test function of HarmonyOS 4.0 for some models, and a total of 35 products have become the first batch of updates and upgrades.

　　In addition, in the second half of 2023, Huawei will launch HarmonyOS 4.0 adaptation updates for Huawei's smart meters, smart screens, routing and other products.

　　It is worth noting that among the first batch of devices supported by Huawei Harmony 4.0, the series of models like Nova first supported the Nova 6 generation, but we didn't see any old glory models in the list. I don't know if the new glory side will transfer the upgrade rights of old users to the past, so that old users can use the latest MagicOS operating system.
