Siri on iOS 13.4 can take you to back to the Home screen
If your iPhone or iPod touch has the iOS 13.4 software or newer, or you have an iPad with iPadOS 13.4 or later, you can try this out for yourself by saying something along the lines of:
“Hey Siri, take me back to the Home screen”
“Hey Siri, go to the Home screen”
“Hey Siri, Home screen”
13.4 的版本，Siri 可以帶你回主畫面，
那捷徑應該也能達成這個指令？
目前想回主畫面還要靠 Launcher 這個 App，
最近才看到個可讓 Safari 背景播放 YouTube 並自動回主畫面的捷徑。
有升到 13.4 的人可以試試看上述的指令。
