some time ago，Huawei at the Mate X2 folding screen flagship launch conference，正式宣布了鴻蒙OS操作系統將在今年4月開啟推送，The first batch of upgraded models may be Huawei Mate X2、Mate 40 series and other models。
Currently，華為還並未正式旗下機型正式推送鴻蒙OS更新。but，According to the latest news from the well-known breaking news blogger @数码闲聊站，華為將在後續的新品手機中直接出廠預裝鴻蒙OS操作系統。Combined with previous revelations，首款預裝鴻蒙OS系統登場的機型有望是Mate 40 Pro 4G version。
It is reported that，Huawei Mate 40 Pro 4G版近日已經通過工信部和3C認證，其中工信部認證信息顯示，該機將搭載“Harmony OS”系統，這也證實了此前的傳聞。
According to previous news，Huawei originally planned to release the pre-installed Hongmeng OS system on the P50 series released in March，However, due to the influence of some uncertainties，Therefore, the P50 series launch conference has been repeatedly postponed，This also delays the debut of the official version of Hongmeng OS system，並改為Mate 40 Pro 4G首發搭載。
in addition，根據近日網友公佈的鴻蒙OS開發者公測版界面顯示，該系統相比華為此前的系統採用了全新的視覺設計，且啟用了全新的通知欄和快捷控制中心，可支持直接進行IoT智能設備管理等，這也體現出了鴻蒙分佈式系統的強大生態能力。
hardware，此次華為Mate40 Pro 4G版與之前的5G版本幾乎完全一致，The chip is also equipped with the Kirin 9000 flagship chip，Adopt 5nm process，Integrated 15 billion+ transistors，It's just that some unknown factors have cancelled the support for 5G，But the performance is completely synchronized。
