Apple has released a second build of iOS 26.4 beta 3 and iPadOS 26.4 beta 3 for developers. The new versions arrive just three days after the first beta 3 builds, indicating Apple is quickly addressing issues discovered during testing.
Both updates are now available as over-the-air downloads for developers already running the iOS 26 and iPadOS 26 beta profiles.
Apple has not published release notes for this revised beta. Quick follow-up builds like this typically focus on bug fixes, performance improvements, and stability changes rather than introducing new features.
Still, iOS 26.4 and iPadOS 26.4 are shaping up to be meaningful mid-cycle updates with several changes already uncovered in earlier betas.
New features coming in iOS 26.4 and iPadOS 26.4
Testing so far has revealed updates across Apple Music, system settings, and connectivity features.
Some of the most notable additions include:
• Redesigned Apple Music album and playlist views
• A new AI-powered Playlist Playground feature in Apple Music
• Per-device Personal Hotspot data usage reports
• Improvements to video podcast playback in Apple Podcasts
These updates appear in both iOS and iPadOS versions of the beta.
Apple is also testing end-to-end encrypted RCS messaging, a major potential upgrade that could eventually enable more secure messaging between iPhone and Android users.
Additional system improvements
A few other changes discovered in the beta cycle focus on security and platform capabilities.
For example, Stolen Device Detection is now enabled by default, strengthening protections against theft and unauthorized access.
Meanwhile, Apple continues to work on CarPlay video support, which has been gradually evolving throughout the iOS 26 beta cycle.
Earlier versions of the iOS 26.4 beta also introduced smaller interface tweaks and refinements across system apps.
