Apple has officially released iOS 26.4 Beta 4, bringing several improvements and refinements ahead of the upcoming public release. The latest beta update focuses mainly on performance optimizations, bug fixes, and small feature upgrades across the system.
The update introduces new emojis, accessibility changes, improvements to Apple Music and the Health app, and a new Camera Audio Zoom feature designed to enhance video recording.
Here’s everything new in the latest iOS 26.4 Beta 4 update, including supported iPhones and whether you should install the beta version.
iOS 26.4 Beta 4: What’s New
New Emojis Added
Apple continues expanding its emoji library with several new characters in iOS 26.4. These new emojis allow users to communicate more creatively across messaging apps and social media platforms.
The update includes emojis such as:
- Trombone
- Bigfoot-style creature
- Gender-neutral ballet dancer
These additions follow Apple’s regular emoji updates based on the latest Unicode releases.
Accessibility Improvements
Apple has made a small but meaningful accessibility change in this update.
The option previously called “Reduce Highlight Effects” has now been renamed to “Reduce Bright Effects.”
This feature helps users who are sensitive to bright animations or flashing visuals on their screens.
Camera Audio Zoom Feature
One of the notable additions in iOS 26.4 is the Camera Audio Zoom feature.
When recording video and zooming in on a subject, the iPhone will now automatically focus its microphones toward that subject. This helps reduce background noise and capture clearer audio.
This feature is especially useful for content creators, vloggers, and mobile videographers.
Apple Music Improvements
Apple Music also receives several refinements in iOS 26.4.
The update brings:
- Improved playlist management
- Better music recommendations
- Faster loading for large music libraries
- Enhanced music discovery
These changes aim to provide a smoother listening experience for Apple Music users.
Health App Updates
The Health app now includes a new metric called Average Bedtime.
This feature analyzes sleep data and helps users understand their regular sleep schedule. It can provide insights into sleeping habits and encourage better sleep consistency.
Performance and Bug Fixes
Since iOS 26.4 Beta 4 is close to the final public release, Apple has mainly focused on improving system stability.
The update includes:
- Performance optimizations
