Over the years, the outside world has also criticized iOS's default home app for not being allowed to change. For example, the default email program uses Apple Mail, and the default HomePod music service uses Apple Music.
HomePod may be Spotify's default service
Recently, it is reported that Apple will allow users to change the default email application and music application, that is to say, in the future, iPhone can change the default email application to Gmail, and HomePod may also set Spotify as the default music service.
Earliest waiting for iOS 14
However, it is estimated that such a large-scale change will have to wait for the iOS 14 revision as soon as possible. The news of iOS 14 will be announced in WWDC in June this year.
