no. HarmonyOS system, Android system and ios system are in a parallel relationship, and they are all operating systems.

HarmonyOS OS is a "future-oriented" operating system, a distributed operating system based on microkernel and facing all scenes. Now it has been adapted to smart screens, and it will be adapted to mobile phones, tablets, computers, smart cars, wearable devices and other multi-terminal devices in the future.

HarmonyOS OS has three characteristics:

1. The system developed for the future development trend has a higher starting point than Google Microsoft;

2. Facing the whole scene, all intelligent devices are coordinated, so all devices can interact in the future, and the ecology is very extensive;

3. Distributed. Similar to modularization, different architecture components are matched according to different devices, which makes the system efficient and simple.

Advantages of HarmonyOS system:

The biggest difference between HarmonyOS system and ordinary system is that it does not directly execute all the contents at the beginning of running the program, but first judges what equipment you are, and then directly executes it through a separate channel. These programs, whether you are a TV, a computer or a mobile phone, all use the same system, but only select a device at the beginning. This system is not for a certain device alone.

The advantage of doing this is that every time you need maintenance, you only need to upgrade the things on the first floor, and the bottom floor below does not need to be moved. It's like the system is a CD player. No matter whose CD you have, you can play it here, as long as you follow the unified Copy program. If you want to listen to other people's music, just change a CD.

In addition to the independence between devices, it will make the function of hardware itself something that can be deployed by the system, such as the camera on the mobile phone. It can even be used by TV or watch through inter-system scheduling, because they use the same system, so they have the ability to communicate with each other.

To realize this function call, there are two conditions. The first is that the hardware of HarmonyOS system must be adopted. The second is that you must log in to the same Huawei account.
