iOS 16.4 has been released by Apple for iPhone 8 and later models. The new update includes features such as the ability to receive notifications from Safari on web apps, as well as a badge count on the home screen. These notifications can also be customised using the Focus mode. Voice Isolation for cellular calls has also been added, which should help with ambient noise reduction. There are also 21 new emojis in total. Duplicate photos and videos in iCloud Share Photo Libraries can now be removed using the Photos app. Apple Books in iOS 16.4 has restored the previously removed page turn animation, and crash detection on the iPhone 14 series has been improved.
