• RCS End-to-End Encryption Testing – Supports encrypted messaging between iPhone and Android devices, with a lock icon indicating secure conversations (availability varies by device and carrier).
• Reduce Highlighting Effects – New toggle under Accessibility > Display & Text Size that softens button and slider edge highlights for better visual comfort.
• Games App Layout Update – Search bar moved from the bottom to the top for improved navigation and cleaner browsing.
• Home Screen Edit Menu Refresh – Features enhanced Liquid Glass transparency for a more modern, layered look.
• Improved Dark Mode Consistency – Control Center pop-up menus now display darker backgrounds that align with system-wide theme settings.

Download iOS 26.4 Beta Steps

To download iOS 26.4 beta, go to Settings > General > Software Update > Beta Updates. Enrollment in the Apple Developer Program is required for developer builds, while the Apple Beta Software Program will provide public access. Before installing, back up your device using iCloud or Finder.

Ensure your iPhone has at least 50% battery and is connected to stable Wi-Fi. After installation, some services like iMessage or FaceTime may require reactivation. Apple also notes that if you enable beta updates but remain inactive for four months, your device will automatically switch back to the public release channel.

StoreKit gains new transaction fields such as revocationType and revocationPercentage, supporting subscription management and refund tracking. Networking fixes resolve CFRunLoopSource leaks related to proxy configurations. SwiftUI, UIKit, and RealityKit also receive refinements, though some animation combinations and Reality Composer export functions remain known issues.
