First of all, the hardware does not support it. We all know that Huawei is developing its own Kirin 985 processor, because it can better adapt to HarmonyOS system, just like Apple system. Your Android phone just can't be installed, not that the system doesn't work, but that all the hardware in the phone is designed to adapt to the Android system, not the Apple system. That's what it means! Some people may say that I successfully updated my computer, but I can ask you, is the system really so stable after you updated your computer? Will it often collapse? In other words, after all, mobile phones are different from computers, because computers and cpu architectures are the same. Since the architecture is the same, it proves that one system can be used, so computers are different from mobile phones.
Another reason is that Google and Huawei have signed an agreement, which means that once Huawei phones with Android system are used, they can't change to other mobile phone systems, because once they are changed, it is equivalent to a breach of contract, but you don't have to worry about this, because the mobile phone manufacturers in China are very authentic in these aspects, and they only use them after paying patent fees, which will not affect the mobile phones used by everyone, at least in China! In addition, people are more worried about the ecological problems of HarmonyOS system, so we can see if there are ecological problems in HarmonyOS system. It was previously reported that the HarmonyOS system is compatible with all Android software. Although I don't know whether it is true or not, if it is true, there will be no ecological problems in HarmonyOS system.
But even if they are not compatible, there is no problem, because it is simple. In our country, there is almost no foreign software on mobile phones, and most of them are domestic software. It can be said that as long as these softwares are compatible, there is no problem at all. After all, this is related to our patriotism!
Summary: Huawei began to develop its own system for our core competitiveness. Huawei has also paid a lot for this system, but even if it pays so much, it is worthwhile. After all, this is our own system in China, so we don't have to worry about system monopoly in the future. It can be said that this is very beneficial to the development of China.
