Below are some of the biggest additions to your iPhone with iOS 16.4. And here's how to download and install the update if you haven't already. For more, see what's new in iOS 16.4.1 and everything to expect from the next major iPhone update, iOS 16.5.
31 new emoji
The iOS 16.4 update brings 31 new emoji to your iOS device. The new emoji include a new smiley; new animals, like a moose and a goose; and new heart colors, including pink and light blue.
The new emoji all come from Unicode's September 2022 recommendation list, Emoji 15.0.
Voice Isolation comes to cellular calls
Voice Isolation was introduced with iOS 15 in 2021, and at the time it worked only on FaceTime calls. Now with iOS 16.4, you can use the feature on your cellular calls too.
When enabled, Voice Isolation can help the person you're on a call with hear you more clearly by muffling background sounds, like kids playing in the other room or construction outside your window. It could therefore cut back on the number of times you have to repeat yourself in a phone call because the other person can't hear you.
Easily find photo duplicates across shared albums
In iOS 16.4, you can easily find duplicate photos in shared albums in Photos. If you share photos with family or friends via iCloud, iOS 16.4 will show you all the duplicates across albums. You can also Merge these duplicate photos.
Support for PlayStation 5 controller
According to MacRumors, iOS 16.4 adds support for the PlayStation 5 DualSense Edge Wireless Controller. You can use the controller to play controller-enabled games from services like Apple Arcade -- a CNET Editors' Choice award pick -- on your iPhone.
