At the Mate X2 folding screen mobile phone conference , Huawei officially announced that starting from April this year, Huawei’s flagship phones will gradually upgrade the Hongmeng OS system. As soon as the news came out, it caused heated discussions among many netizens. Many users of old models are very concerned about whether they can upgrade the Harmony OS and hope to experience the operating system developed by Huawei for the first time.
Today, digital blogger @长安数码君 said that after communication and verification with relevant personnel, the current tentative plan is to carry Huawei’s Kirin 710 chip or higher, regardless of Huawei or Honor, Huawei Harmony OS will be upgraded. (It is temporarily unclear whether or not Kirin 710 is included)
This means that at least mobile phones equipped with chips such as Huawei Kirin 810, Kirin 820, Kirin 820E, Kirin 980, Kirin 990, Kirin 985 and Kirin 9000 can basically guarantee the upgrade of the Huawei Hongmeng OS system.

It is worth mentioning that the blogger said that the above is a tentative upgrade model, and there may be changes in the future. It is only for your reference at this time.
It is understood that Wang Chenglu, president of Huawei’s consumer BG software department, said in an interview that: this year Hongmeng OS system will cover 200 million Huawei mobile phone products.
At the same time, Wang Chenglu also revealed that Huawei will ensure that Hongmeng OS will be covered to more models to the greatest extent. At present, more than 90% of the models on the market will upgrade the Hongmeng OS system.
It is reported that Huawei officially released HarmonyOS, a distributed operating system for all scenarios in August 2019, and put it into use on Huawei smart screens first.
In September last year, Huawei released HarmonyOS 2.0. The new version has undergone a comprehensive upgrade in the three core capabilities of distributed soft bus, distributed data management, and distributed security.
