iOS 17 rumored to include Dynamic Island improvements including new Siri UI and notification upgrades

Apple is allegedly testing two new Dynamic Island improvements ahead of the grand unveiling of iOS 17 at WWDC23 in June, including a new Siri UI and notification upgrades according to an anonymous source who has shared accurate information previously about unreleased Apple software features.
According to the source on Twitter, “many more notifications will be used with Dynamic Island” with iOS 17, suggesting that we could see Apple deepen the role the pill-shaped interactive cut-out on the iPhone’s display has on the core iPhone experience, with users potentially seeing notifications come from the Dynamic Island, similar to how Live Activities are shown currently.
The source says a new Siri UI is being tested with the upcoming update, which could possibly see the animated Siri sphere currently found at the bottom of the iPhone’s screen when the assistant is prompted relocated to the Dynamic Island, allowing the on-screen content to remain visible at all times.
Codenamed “Dawn,” iOS 17 isn’t expected to include as many major improvements as iOS 16 did, which introduced the ability to customize the Lock Screen to allow users to change the look of the date and time with type styles and colour choices, add widgets, relocated notifications, and more however, the update is rumored to boast several “nice to have” features, including several of users’ “most requested features.”
The same source has also claimed that Apple is internally testing interactive widgets for iOS 17, which would allow developers to add scrolling elements or switches to their Home Screen widgets to improve on the present read-only information widgets.
