What’s New in iOS 16.4: Voice Isolation, Dim Flashing Lights, and More!
Apple has released its latest operating system update, iOS 16.4, which includes a range of new features and improvements. One of the most notable additions is Voice Isolation mode, which now works for phone calls as well as FaceTime. This feature prioritises the user's voice and blocks out ambient noise, resulting in clearer audio for both parties involved in the call. Another accessibility option added in iOS 16.4 is Dim Flashing Lights, which automatically dims the display of videos when flashes of light or strobe effects are detected.
iOS 16.4 also introduces 21 new emojis, including animals, hand gestures, and objects. The update brings back the page curl effect for Apple Books, which had been removed in a previous iOS update. Additionally, three new order-tracking widgets have been added for Apple Wallet, in small, medium, and large sizes.
iPadOS 16.4 has added tilt and azimuth support to the Apple Pencil hover feature, allowing users to preview their mark at any angle before applying it. Apple Podcasts has also been updated, with a Channels tab now available in the Library section, showing different networks followed, and “Up Next” allowing users to resume episodes and remove shows they want to skip.
There are some improvements for gamers, too, as iOS 16.4 adds support for the customizable PlayStation 5 DualSense Edge Wireless Controller. Web apps saved to the home screen can now send web push notifications in iOS 16.4, just like on Macs. Furthermore, the update reintroduces the HomeKit architecture update that was pulled from iOS 16.2 due to bugs.
To install the update, users should go to Settings > General > Software Update, and the update should be available for download. However, it may take a few minutes to appear, as Apple's updates can take a little time to roll out to all devices.
