At the Mate9 overseas conference held in Munich, Germany, Huawei officially released a new generation of mobile phone operating system EMUI5.0. Based on the hardware upgrade of Mate9 in flagship machine, the new version of the system deeply optimized the system software, which not only improved the system performance, but also brought a brand-new visual interaction experience, showing users a brand-new Android user experience, which is the most milestone in the history of EMUI. It is undeniable that the launch of EMUI5.0 is a highlight of Mate9. EMIUI 5.0 is deeply developed based on the newly released Android 7.0 system, which also makes it the first customized OS for mobile phones based on Android 7.0 in China, and it can also be ranked in the world. Although Android 7.0 has been officially released for nearly two months, the performance improvement compared with version 6.0 has become a * * * knowledge, but in fact, many released new machines have not caught up with the pace of Android in system upgrade. Compared with the OS version of the flagship model of domestic brands released this year, it is not difficult to find that most of the newly upgraded mobile phone customized OS is still based on Android 6.0 or even 5.0. Huawei has become the first echelon of Android system update. Generally speaking, the domestic mobile phone OS is relatively lagging behind in the upgrade of Android system. According to the update rhythm of the previous Android system, after the system is upgraded once a year, except for Google's "pro-son" Nexus system and Google Play version of the mobile phone, other Android OS must first obtain the source code authorization supported by the chip from Google, and then customize and optimize the software system. This process needs more time and a lot of adaptation tests. The same is true of this Android 7.0 upgrade. Since the release of internal testing, domestic mobile phone OS manufacturers are eager to adapt to the upgrade and experience the good performance improvement of the latest system. As an international mainstream smartphone manufacturer, Huawei can give priority to all-round technical optimization and upgrade in terms of system experience and performance based on Android 7.0. From this point, we can see Huawei's technical research and development strength in adapting and upgrading the new version of the system. Of course, in terms of system experience and performance, there are obvious differences between different Android customized OS. Even with the same Android machine, the actual fluency of different brands of mobile phones will be different. This actually depends on the optimization degree of customized Android OS. The more thorough the system optimization is, the better the functional experience and system fluency will be. Compared with domestic OS, EMUI5.0 has great advantages in the upgraded Android version and system optimization performance experience. EMUI5.0 has been ahead of other OS EMUI5.0 in solving the stuck problem, and its performance and fluency have been greatly improved compared with the previous generation. Some core components of the Android system are deeply optimized, and an intelligent perceptual learning system with deep learning function is innovatively embedded, which can reasonably schedule the CPU and memory resources of the system, thus solving the common phenomenon of the Android system being stuck, realizing the unique performance advantage of "live quickly and die quickly", which completely solves the long-term problem of the Android system being stuck. In optimizing the experience and performance of Android system, each domestic mobile phone OS has its own emphasis. For example, MIUI 8 has made many optimizations to the system memory, and the function of "in charge of the system" has strengthened the protection of personal privacy. For example, the mobile phone housekeeper of Color OS 3.0 has improved in system slimming and application encryption. But the system optimization of EMUI5.0 is not only reflected in the brand-new design experience, but also in many convenient and practical intelligent services and security guarantees. Its greatest success lies in its breakthrough in performance. Before this, Android stuck has become a chronic disease in the mobile phone experience. Almost all mobile phone OSs have tried to optimize and solve this problem, but often the most fundamental stuck problem has not been solved. Various additional "black technology" functions have made the mobile phone system more and more bloated, and the system performance and user experience are even less satisfactory. At present, many system optimizations of Android OS are reflected in performance, which are often palliative, and some are shallow optimizations based on UI experience. In contrast, EMUI5.0 pays attention to "making the best use of everything" in system optimization and upgrade, deeply integrates with Kirin 960 chip, and gives full play to Huawei's own technical advantages of combining software and hardware. In addition, in-depth analysis of Android system to solve the problem of system jam, using enhanced file system, timely reduce the burden of file fragmentation, even if used. Customization and optimization of Android OS is a very heavy and energy-consuming task, and many mobile phone manufacturers have invested funds and technical support in this regard. It can be seen that Huawei is mature in deep customization based on Android system, ahead of other Android mobile phone manufacturers.
