Introducing HarmonyOS 2.0 – Huawei’s new software platform
Harmony operating system which The first time almost two years ago in August 2019 introduced and it was also referred to as HongMeng OS among the first reactions of Huawei than Restrictions created for this company were by the former president of the United States, which despite being removed They are still valid in the last year. According to these restrictions, Huawei lost access to Google services and after some time with the unveiling of HMS or Huawei Mobile Services and the AppGallery store accelerated their efforts to deal with these limitations.
Harmony operating system is a platform designed for a variety of devices, which was first presented for Internet of Things devices such as smart home equipment and smart displays, and after a while it was provided to smart TVs. This software solution is now used in more advanced devices such as mobile phones, tablets and smart watches, and thus, considering the unfavorable perspective of the political relations between China and the United States and the little hope of removing Huawei’s restrictions, it is not very similar to a temporary solution and probably within a short period of time It will become one of the leading platforms in the mobile computing world. Of course, according to Huawei, the Harmony platform is not a direct replacement for the Android operating system, but it is an example that bypasses Android and empowers It will handle a growing array of connected devices. Wang Chenglu, head of Huawei’s consumer software business, said: “No matter how many devices [are] connected, we want to make sure that users can access them as easily as they can from one device. They used, let them use. >
Before addressing the features of this platform, it is necessary to note that Harmony, despite the same name, has a different structure in different devices and naturally a different platform for mobile phones, smart watches and Internet of Things devices. Provide. Due to this fact, HarmonyOS should be divided into two completely different operating systems, where the first operating system is intended for smart watches and Internet of Things devices and is apparently not far from the company’s open source LiteOS platform. The second user interface, which is used in mobile phones and tablets, is a variant of Android that uses the Linux kernel, and thus, even though the services of Google does not have a place in it, but it is possible to install and run various programs of this operating system (provided they are not incompatible).
In the following, we will discuss the new features introduced in HarmonyOS 2.0.
New control panel
The new control panel of the Harmony operating system, which looks similar to the similar example in iOS It cannot be easily passed, according to the local expectation to access various toggles, including phone communication options, changing the brightness of the screen and controlling the music being played, and it can also be used to manage the devices connected to the device. Huawei calls several devices connected to each other in this way as Super Devices.
Among the new points in this control panel is its music playback widget, through which if there are several applications for music streaming, each one is available separately, as well as the source Sound playback can also be selected as desired.
The ability to control the connected devices turns the device with the Harmony operating system into a control hub to view the status of other devices and the status of each device can be viewed live at any moment.
A key feature In this section, it belongs to the Super Device widget, by touching it, the main device is placed in the center of a circle, and other devices ready to connect can be seen around it. become 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 while playing music as one of the uses of this feature, where there is no need to go through the usual and time-consuming pairing process. Huawei talks about the use of two technologies to ensure that the sound and image are in sync, in the first one, soft clock synchronization, all devices use the same reference clock, and in the second one, how to overcome interference to prevent issues such as Jittering and increased delay and packet loss have been noticed.
Quick connection of phone and tablet or phone and PC to transfer images and other types of files is one of the other practical examples of forming a Super Device. Of course, it is also necessary to mention that the process of connecting the phone to the PC apparently requires special laptops from Huawei.
Many household appliances these days are equipped with smart features that can be used to achieve distinctive features. However, accessing these features requires identifying, installing and launching applications related to each device, which is apparently not very common, and according to Huawei Only 10% of users install the relevant applications, and among those who install these applications, only 5% actually use the device’s smart features. However, Huawei intends to change this statistic by using the Harmony operating system. As an example in this context, it is pointed out to bring the phone close to an oven equipped with the Harmony platform, which leads to calling the relevant widget and displaying cooking instructions.
Changing the temperature of the refrigerator and freezer in a similar way is another function that can be mentioned in this section. According to Huawei, the Harmony operating system has been available to the company’s partners since September 10, 2020, including home appliance brands, software solution developers, and so-called module manufacturers, among which are some familiar names such as Haier, Midea, and Tissot. . Huawei’s Control Panel is currently available for smartphones, tablets, and smartwatches, and the company hopes to bring this panel to other devices with Harmony Platform displays in the future.
Home page changes
This time, by introducing what are called distributed application framework and Atomic Services, Huawei talks about a new feature that if the desired application matches the two mentioned features, the icon of that application can be changed. He pulled it up and displayed the key information of the application without opening it.
On the home page of the Harmony platform, the so-called atomic services are available through widgets; In this case, if information is important to you and you need to see it at all times without unlocking your phone and opening its application, you can simply pin it to the home screen like a sticky note.
In this case, you can define different screens for different scenarios, for example, one screen for entertainment, another for sports, and another screen for work.
Another feature introduced for the home page belongs to the time of creating a folder, in which a folder is created New, similar programs are shown to the user and after confirming these programs are automatically added to this folder.
Converting normal folders to smart folders to display internal information without opening them is one of the less important things mentioned in the introduction of the second version of Harmony.
Access to services on other devices
Users normally use applications to access a service, which is normal and common, but if the main device is not available, what is the way to use the desired service? ? Huawei sees the answer in HarmonyOS; For example, you can consider a smartphone and a tablet that are combined on the Harmony platform and form a super device; In this mode, Task Center displays the current tasks on both devices, and to transfer a task from the phone to the tablet, it is enough to drag it on the tablet icon at the top of the screen, and thus the desired task is easily transferred to the larger screen of the tablet. he does. In this way, it is possible to check the programs running on the mobile phone on the tablet and even continue them on the tablet.
Service Widgets are one of the key options of the Harmony platform, which were mentioned before. To create a widget service, it is enough to drag the icon of a corresponding application upwards to have instant and immediate information of that application without the need to open it. The size of this widget can be changed according to the user’s wishes and it can be placed anywhere on the home screen.
Service Widgets can also be used to access what are called Atomic Services, which are easily invoked and shared in ServiceCenter without the need to download or install any additional programs. The widget service can be moved between different devices with the Harmony platform, for example, if you are interested in reading news on your phone and sending it to your friends, you can easily send the widget service to the desired person, and he can also without installing any additional program. Reading will be the same news.
speed and performance quality
Huawei in introduction Harmony operating system has announced the optimization of this platform, including the kernel and hardware layer, with the help of which the performance of HarmonyOS has increased compared to the EMUI user interface based on Android. To back up its claim, the company points to 20 percent of users experiencing RAM limitations after using their device for 36 months, after which the device starts to slow down on the Harmony platform, but with the help of what it calls “numerous The mentioned “innovation” ensures that performance does not slow down even when the RAM memory is almost full.
Exclusive DGraphicEngine technology
In this technology, both CPU and GPU are used together for timing and intelligent redrendering. In addition, by separating the rendering logic from the service processing logic, these two do not interfere with each other’s work, and according to Huawei, the graphics performance is smoother and the frame rate is improved.
Cases like this reduce the system load for video processing and Apart from running apps more smoothly, they also get better battery life. For example, Mate 40 Pro when running a The particular game is mentioned to last 4.7 hours with EMUI under Android and up to 5.1 hours with HarmonyOS.
Security and privacy matters
Among the security and privacy matters mentioned by Huawei in the Harmony platform is a feature called Collaborative authentication, during which when unlocking the phone screen In addition to facial recognition, smart watch data is also used.
According to Huawei, the new version of the Harmony operating system will be available for nearly 100 different devices from the day of its launch, including the Mate 40 and Mate 30, series P40, tablets MatePad Pro , Nova 8 series, nova 7 and nova 6 and some older devices including the Mate 10, Nova 5, Nova 4 and Nova 3 and series P10 pointed out.
