Founded in 1987, Huawei is a leading global provider of information and communications

Operating systems:
 In 2019, Huawei announced 
HarmonyOS, an epoch-making distributed operating 
system that is applicable across all scenarios. 
HarmonyOS and its underlying distributed technology 
have been designed for a world where everything is 
connected. HarmonyOS helps create “super devices” 
by pooling the software and hardware resources of 
previously physically-independent devices, to transform 
the ambition of a Seamless AI Life into a full-blown 
reality. HarmonyOS helps to ensure that users always 
have an intelligent experience, which seamlessly shifts 
across devices when scenarios change.
In 2020, Huawei upgraded HarmonyOS to Version 2.0, 
which brought comprehensive improvements to the 
existing distributed capabilities, including software bus, 
data management, and security. Huawei also introduced 
an adaptive UX framework that allows developers to 
quickly reach tens of millions of new devices and users. 
The HarmonyOS 2.0 Developer Beta for smartphone 
app developers was launched in December 2020.
Huawei extensively supports developers in the HarmonyOS ecosystem, providing expert-level support, valuable training courses and 
easy-to-access materials, open-minded developer communities, and much more. Over 100,000 developers have received training from 
Huawei and are actively contributing to a thriving HarmonyOS ecosystem.
Stars shine through even the darkest night
Each of our developers is a star
Together they form a brilliant array 
That will light the way

2020 Annual Report
 
       
47
The EMUI 11 operating system, which powers the 
HUAWEI Mate 40 Series and Huawei’s other flagship 
smartphones, takes advantage of the core distributed 
technology of HarmonyOS, enabling interactions 
beyond smartphones. Multi-screen Collaboration 
supports multitasking, and allows multiple smartphone 
apps to be controlled simultaneously through a 
connected PC. A smartphone can be turned into an 
electronic whiteboard with just a single tap, and screen 
mirroring is possible between a smartphone and 
another device.
In accordance with its open-source plan, HarmonyOS 
has been opened to devices with 128 KB to 128 MB 
RAM, such as smart screens, watches, and head units, 
since September 10, 2020. In April 2021, HarmonyOS 
will be opened to devices with 128 MB to 4 GB RAM. 
In October 2021, it will be opened to all devices with 
over 4 GB RAM. All related code will be donated to 
the OpenAtom Foundation of China.
In terms of HarmonyOS app development, 
comprehensive HarmonyOS 2.0 system capabilities, 
a multitude of APIs, and powerful app development 
tools like the DevEco Studio simulator have been 
made publicly available to smartphone app developers. 
This is facilitating efficient development of apps for 
a fully connected world. These apps will provide our 
consumers with complete access to the full range 
of benefits offered by a Seamless AI Life across all 
scenarios, including smart office, fitness & health, 
smart home, easy travel, and entertainment. More 
than 120 mainstream apps, including JD.com, Baidu, 
Youku, and iFLYTEK, have started innovating based on 
HarmonyOS in order to bring consumers a completely 
new, intelligent experience.
In the IoT hardware domain, HarmonyOS’s 
revolutionary distributed technology will help hardware 
vendors turn products into services, transforming their 
business. Software innovations will be channeled to 
bring about differentiated and flexible hardware usage. 
Hardware resources from all connected devices within 
the HarmonyOS ecosystem will be pooled together, 
enabling partners to extract more value by selling 
services on an ongoing basis, rather than being limited 
to one-time purchases.
Multi-device interconnectivity has now become 
seamless, even at the very bottom layer, where 
connections are unaffected by differences in software 
or hardware. For instance, users can simply tap their 
phone against a home appliance to establish an 
instant connection, and the appliance’s information 
will be visualized on the phone screen. Connected 
appliances will also be able to “remind” their users 
about their status, making their users’ lives much more 
convenient. More than 20 hardware vendors including 
Midea, Joyoung, and Robam have already joined the 
HarmonyOS hardware ecosystem, and launched a 
number of home appliances powered by HarmonyOS.
