Huawei mate30 HarmonyOS system has no 5g option.

Huawei Mate 30 series phones don't have the 5G option of HarmonyOS system, mainly because the HarmonyOS system is still in the stage of continuous development and perfection. At present, Huawei's HarmonyOS system is mainly aimed at devices supporting 4G networks, so Mate 30 series phones have no 5G option for the time being.

There may be several reasons for this:

1. Technical adaptation: HarmonyOS system may not be fully adapted to devices supporting 5G network when it goes online. 5G technology is relatively new, so it is necessary to adjust and optimize the hardware and software accordingly, so as to realize the smooth operation on HarmonyOS system.

2. Time goes by: The development of HarmonyOS's system is a gradual process. Maybe when Mate 30 series mobile phones were released, the related technologies of 5G were not fully mature, so the 5G option was not included.

3. Market demand: When Mate 30 series mobile phones were released, the popularity of 5G networks had not reached a wide level, so 5G may not be a priority factor in design and development.

Of course, with the passage of time and technological progress, the future version of HarmonyOS system may gradually support the 5G network and provide corresponding options in Huawei's new mobile phones. Huawei has been actively promoting the development of 5G technology, and future products may pay more attention to the application and experience of 5G.

Extended content: As an operating system independently developed by Huawei, HarmonyOS may become the core of Huawei's product ecology in the future. Huawei plans to apply HarmonyOS system to various devices, including smart phones, smart wearable devices and smart homes. With the continuous improvement of HarmonyOS system and the expansion of its application scope, we can expect that Huawei's products will provide richer and better user experience in the future.
