No, not that I am aware. Using only blocks users cannot detect an incoming call in the background with the phone component.
You might be able to use a Background extension (for example Background Tasks extension [3.8 A] 🥳
) with the Phone component. Experiment (but I don't believe that would work; you could try). Otherwise search for a Phone extension or write your own extension or use the professional Android Studio to write your app (see this google android studio detect incomming phone call - Google Search )
