On Wednesday, June 2, 2021, Huawei unveiled the second version of Harmony platform called HarmonyOS 2.0, which will be present in a wide range of the company's devices, from smartphones and tablets to smartwatches and IoT devices. This platform, which is apparently based on the open source version of Android (at least in the version for phones and tablets), has some differences from normal Android and new features can be seen in it. The second version of Harmony will not only be used in the new and future devices of Huawei, but also a set of previous devices equipped with Android will be able to update it.
Harmony operating system for the first time close to two Introduced in August 2019 last year, it was also known as HongMeng OS. It was one of Huawei's first reactions to the restrictions imposed on the company by the former US president, who, despite being ousted last year, is still They remain strong. Huawei lost access to Google services under these restrictions, and after a while, with the unveiling of HMS or Huawei Mobile Services and the AppGallery Store, it accelerated its efforts to overcome these restrictions.
Harmony OS is a platform designed for a diverse set of devices, first introduced for IoT devices such as smart home devices and smart displays, and later made available for smart TVs. This software solution is now used in more advanced devices such as mobile phones, tablets and smartwatches, and thus, given the unfavorable outlook for Sino-US political relations and the low hopes of lifting Huawei's restrictions, it does not look like a temporary solution. It will become one of the role-playing platforms in the world of mobile processing. Harmony platform, of course, according to Huawei, is not a direct alternative to the Android operating system, but an example that by passing through Android will take on the task of empowering a growing set of connected devices. "No matter how many devices are connected, we want to make sure users can access them as easily as from one device," said Wang Chenglu, head of customer software business at Huawei. They used to use it. "
ago From the features of this platform, it is necessary to pay attention to the fact that Harmony, despite the same naming, has a different structure in different devices and naturally provides a different platform for mobile phones, smart watches and IoT devices. Given this fact, HarmonyOS should be divided into two completely different operating systems, where the first operating system is intended for smartwatches and IoT devices, and apparently not far from the company's open source LiteOS platform. The second user interface used in mobile phones and tablets, but a kind of Android that uses the Linux kernel, and thus, although Google services do not yet have a place in it, but you can run various programs of this operating system (provided it is not incompatible and run) .
Here's a look at some of the new features introduced in HarmonyOS 2.0.
The new Harmony OS operating system control panel, which looks similar to a similar example in iOS, is not expected to be accessible locally. Various tags are being played, including phone connectivity options, screen brightness changes, and music control, and can also be used to manage devices connected to the device. Huawei calls several devices connected in this way Super Devices.
One of the new points in this control panel is its music playback widget, through which there are several applications for streaming music, each of which is available separately, and also the audio source can be selected as desired. .
Ability to control connected devices, device with The Harmony operating system is converted into a control hub to view the status of other devices, and the state of each device can be viewed live at any time.
Another key feature in this section belongs to the Super Device widget, which by touching the main device is in the center of a circle and other devices are ready. To connect around the saw . In this case, you can connect these two devices just by dragging and dropping the desired icon next to the main device. Huawei mentions the easy and hassle-free connection of a speaker when playing music as one of the applications of this feature, in which there is no need to go through the common and time-consuming pairing steps. Huawei talks about using two technologies to ensure that audio and video are in sync. In the first, soft clock synchronization, all devices use the same reference clock, and in the second, how to overcome interference to avoid issues such as Jittering and increasing latency and packet loss have been noted.
Quick connection of phone and tablet or phone and PC is another example of creating a Super Device for moving images and other types of files. Of course, it is also important to note that the process of connecting the phone to the PC apparently requires special laptops from Huawei.
Many home appliances these days have features They are intelligently equipped with the help of which distinct capabilities can be achieved. Access to these features, however, requires identifying, installing, and launching applications related to each device, which is apparently not very common, and according to Huawei, only 10 percent of users install the relevant applications, and only 5 percent of those who install these applications. They really take advantage of the smart features of the device. Huawei, however, intends to change this statistic by using the Harmony operating system. An example of this is moving the phone closer to an oven equipped with a harmonic platform, which leads to calling the corresponding widget and displaying the cooking instructions.
Changing the temperature of the refrigerator to a similar one Other functions mentioned in this section. According to Huawei, Harmony's operating system has been available to the company's partners since September 10, 2020, including home appliance brands, software developers, and so-called module makers, including some familiar names such as Haier, Midea, and Tissot. . Huawei control panel is currently available for smartphones, tablets and smartwatches, and the company hopes to provide this panel in the future for other devices with a harmonic platform display.
Huawei this time with the introduction of what distributed called application framework and Atomic Services speaks of a new feature that if the application matches the two features mentioned, you can drag the icon of the program up and display the key information of the application without having to open it.
Home page of Harmony Platform, what services It is called Atomic services; it is available through widgets; In this case, if the information is important to you and you need to view it at all times without having to unlock the phone and open the application, it can be easily pinned to the home screen like a sticky note.
In this case, you can create different pages for Defined different scenarios, such as one page for entertainment, another for sports, and one page for work.
Another feature introduced for the Home page belongs to the time of folder creation, in which a new folder is created, similar programs are shown to the user, and after confirming these programs, automatically These folders are added.
Convert ordinary folders to smart folders for display Internal information without the need to open them is another not so important thing that is mentioned in the introduction of the second version of Harmony.
Users normally have access to a Services use applications that are common, but if the main device is not available, what is the solution to use the service? Huawei sees the answer in HarmonyOS; For example, we can consider a smartphone and a tablet, which are combined in a harmonic platform and form a super device; In this case, the Task Center displays the current task on both devices, and to transfer a task from the phone to the tablet, just drag it on the tablet icon at the top of the screen, and thus the task can be easily transferred to the larger screen of the tablet. he does. In this way, it is possible to check apps running on mobile on the tablet and even continue them on the tablet.
Service Widgets One of the options They are the key to the Harmony platform mentioned earlier. To create a widget service, simply drag the icon of a compatible application upwards to have instant and immediate information about that application without having to open it. The size of this widget can be changed at the user's discretion and it can be placed anywhere in the home screen.
Widgets can be used to access what Atomic Services can also be used, which are easily called and shared in the service center without the need to download or install any additional applications. Widget services can be switched between different devices with a harmonious platform. For example, if you are interested in reading news on the phone and sending it to friends, easily send the widget service to the person and he can install any additional program without Reading will be the same news.
Introducing the Harmony operating system, Huawei has announced the optimization of the platform, including the kernel and hardware layer, which have increased the performance of HarmonyOS compared to the EMUI-based Android user interface. To prove its claim, the company cites the experience of ROM limitation among 20% of users after using the device for 36 months, after which the device begins to slow down on the Harmony platform, but with the help of methods such as "some This innovation ensures that performance does not slow down even when the ROM is almost full.
In this technology, both CPU and GPU are used together for intelligent scheduling and rendering. In addition, by separating logical rendering from service processing logic, the two do not interfere with each other, and according to Huawei, the graphics performance is smoother and the frame rate is improved.
Such cases also reduce the system load for video processing and apart from smoother execution of programs, higher battery life They also get it. For example, the Mate 40 Pro is mentioned when running a special game, which will last 4.7 hours with EMUI under Android and up to 5.1 hours with HarmonyOS.
including security and privacy issues Huawei on the Harmony platform has a feature called Collaborative authentication, which uses smartwatch data in addition to face recognition when unlocking the phone screen.
A new version of the Harmony operating system will be available for nearly 100 different devices from the day of unveiling, according to Huawei These include the Mate 40 and Mate 30, P40 series, MatePad Pro tablets, Nova 8, Nova 7 and Nova 6 series, and some older devices such as the Mate 10, Nova 5, Nova 4 and Nova 3, and the P10 series. .
