I can confirm that screen happens when you "search" within RecentsThis user here https://www.reddit.com/r/iOSBeta/s/z9ZBuedQcn says he has DB6 and in his screenshot the call icon is active in recent calls! Either he doesn't have DB6 or the call icon shows when you search in Recents (obviously a bug). I have asked him but hasn't replied yet.
So yea... two UIs in one app, at least one side gonna change before production release
