Started yesterday，Huawei's Hongmeng 2.0 system has begun public beta，Many people have signed up，And received a push from Huawei，The system switches from AndroidOS to HarmonyOS。
For netizens，升級鴻蒙OS會有什麼變化？這個問題是最關鍵的，也是最影響他們日常使用的，Judging from the existing feedback，fluency、日常使用還是沒問題的，甚至有人覺得比安卓系統還要流暢一些。
升級HarmonyOS之後還有一個懸念，那就是原來的系統服務怎麼辦，特別是安卓上離不開的谷歌服務，華為會怎麼處理呢？

微博大V@Xiao1u已經在自己的華為Mate40 Pro+手機上升級了鴻蒙，之後發現谷歌服務完全不受影響，可以繼續使用。
華為之前沒有解釋過如何兼容谷歌服務的，不過把谷歌的服務也看作APP應用的話，那HarmonyOS兼容谷歌服務倒也不是做不到。
此前華為解釋過HarmonyOS與其他手機系統的區別，It means that Hongmeng OS is not a replacement for Android，Not a copy of iOS either，The real development of Hongmeng began in May 2016，In fact, Huawei has been doing it for 5 years，Hongmeng OS is positioned as an operating system in the era of Internet of Things。
