Apple is currently in the mid-cycle testing phase for its next major software revision, iOS 26.3. Following the release of the second developer and public betas in mid-January, the update is approaching its final stable launch for iPhone 17 and iPhone 16 users.
The update mainly improves how iOS works with other platforms, meets new European Union regulations, and fine-tunes messaging features.
It comes after the December release of iOS 26.2, which added offline lyrics and improved gaming filters.
Expected Release Window for USA and UK
Based on Apple’s past release pattern for “.3” updates, iOS 26.3 is expected to launch in the week of January 26, 2026. Apple usually releases these updates on the Monday after Martin Luther King Jr. Day in the United States.
Users in the UK and USA can expect the update to become available simultaneously, likely at 10:00 AM PST / 6:00 PM GMT. If the update does not meet the January 26 target, a release in the first week of February is the secondary probability.
End-to-End Encrypted RCS Messaging Framework
A primary technical addition in iOS 26.3 is the backend infrastructure for end-to-end encrypted RCS messaging.
This feature utilizes the RCS Universal Profile 3.0 to secure cross-platform conversations between iPhone and Android devices.
While the software provides the framework, activation remains dependent on carrier support.
Initial rollout is expected to vary by network provider in the USA and UK, as carriers must implement the 3.0 profile to enable the encryption layer.
iPhone-to-Android transfer tool
The update introduces a native iPhone-to-Android transfer tool, developed in collaboration with Google.
This utility allows users to migrate photos, contacts, and calendar data directly between devices without requiring third-party applications.
Additional changes discovered in the beta include:
- Wallpaper Gallery: A dedicated section for Weather-based wallpapers, separate from the Astronomy category.
- Apple Music: Support for offline lyrics, allowing text-syncing for downloaded tracks without an active data connection.
- Unity Collection: The 2026 “Black Unity” wallpaper and matching Apple Watch face.
EU Compliance and Interoperability
To comply with the Digital Markets Act (DMA), iOS 26.3 introduces Notification Forwarding for users within the European Union.
This allows iPhone alerts to be mirrored on third-party smartwatches and wearables, a function previously exclusive to the Apple Watch.
The update also adds proximity-based quick pairing for third-party Bluetooth accessories.
This enables a seamless setup experience for non-Apple earbuds and headphones, similar to the native “pop-up” pairing found with AirPods.
Device Compatibility and Installation
iOS 26.3 is compatible with the iPhone 11 and newer. This includes the current flagship iPhone 17 series and the previous iPhone 16 line-up.
Users on the iPhone XS and XR generations will likely remain on legacy security paths, as they are not supported by the iOS 26 architecture.
To prepare for the update, users should ensure at least 6GB of available storage and a recent iCloud backup. Once released, the update will be available via Settings > General > Software Update.
