Apple has released iOS 26.4 Beta 4 for developers and public beta testers, bringing several improvements ahead of the final public release. The update focuses on performance optimizations, new emojis, accessibility tweaks, and improvements across system apps like Health, Camera, and Apple Music.
If you’re wondering what’s new in iOS 26.4, which iPhones support it, and whether installing Beta 4 is safe, here is the complete guide.
iOS 26.4: Full List of New Features
1. New Emojis
iOS 26.4 introduces several new emoji characters to expand the iPhone emoji library. Some of the highlights include:
- Trombone emoji
