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 可以带你回主画面，
那捷径应该也能达成这个指令？
目前想回主画面还要靠 Launcher 这个 App，
最近才看到个可让 Safari 背景播放 YouTube 并自动回主画面的捷径。
有升到 13.4 的人可以试试看上述的指令。
