In the details, unlike Android and iOS, HarmonyOS was not developed based on Linux and Unix, which allows Huawei to overcome a lot of technical limitations compared to the systems of Google and Apple.
The architecture adopted on Harmony allows it to be faster and smoother compared to Android, because it will consume less RAM to run. In addition, the Chinese system has been developed in open source, which allows developers to make various modifications that correspond to their needs, but also to other market players to adopt this system to their equipment, and this, the same as Android’s Open Source Project (AOSP, open source version of Android). However, developers will not be able to change the core of the system, which remains closed.
