Apple has released iOS 18.3, bringing upgrades to Visual Intelligence and changes to notification summaries.
iOS 18.3 brings changes to the Apple Intelligence notification summaries feature, after multiple complaints from news outlets.
Due to this, Apple has made the following changes to notification summaries in iOS 18.3:
- Notification summaries have been temporarily disabled entirely for the News & Entertainment category of apps. Apple says the feature will be re-enabled for this category in a future software update as it continues to refine the experience.
- Notification summaries are now denoted by italicized text on the Lock Screen. This helps better distinguish them from normal notifications.
- You can now disable notification summaries for an app directly from the Lock Screen or Notification Center by swiping, tapping “Options,” then choosing the “Turn Off Summaries” option.
- When you enable notification summaries, iOS 18.3 will make it clearer that the feature – like all Apple Intelligence features – is a beta.
- In the Settings app, Apple now warns users that notification summaries “may contain errors.”
iOS 18.3 brings two new features to Visual Intelligence for iPhone 16 users:
- You can now add an event to Calendar from a poster or flyer. From the Visual Intelligence interface, just take a picture of that poster or flyer and Apple Intelligence will recognize the date and time of the event and add it to your calendar.
- Visual Intelligence can now easily identify a broader range of plants and animals.
Apple Intelligence will be enabled automatically for users new or upgrading to iOS 18.3. This means that the features are no longer opt-in, but rather opt-out.
“For users new or upgrading to iOS 18.3, Apple Intelligence will be enabled automatically during iPhone onboarding. Users will have access to Apple Intelligence features after setting up their devices,” Apple stated.
To disable Apple Intelligence after updating to iOS 18.3, you can go to the Settings app, choose “Apple Intelligence & Siri,” then disable the Apple Intelligence toggle.
iOS 18.3 includes some smaller changes and improvements. The update addresses a common complaint about the revamped Calculator app that was introduced first with iOS 18.
With iOS 18.3, you can once again hit the equals button multiple times to perform new operations.
