Apple today released the Release Candidate version iOS 15.4 and iPadOS 15.4 to developers. The RC version comes after five beta releases that were released over a span of one month.
The RC build of iOS 15.4 is the one that Apple should release to the public next week provided no major bugs are reported with the build until then.
iOS 15.4 will be a major point release of iOS 15 that brings several new features like Face ID with a mask, improved ProMotion support, AirTags anti-stalking changes, new emoji, and more. For iPhone users, the key new addition will be Face ID with a Mask that makes it possible to use the face unlock feature while wearing a mask. Apple achieves this by scanning the area around the eye, with the feature only being available on the iPhone 12 and iPhone 13. You can follow our guide on setting up and using Face ID with a mask on your iPhone.
For iPadOS users, the update will also add the much-hyped Universal Control feature that the company first demoed at WWDC 2021. There are plenty of other changes and new features in iOS 15.4 and iPadOS 15.4 that are worth checking out.
You can download the iOS 15.4 or iPadOS 15.4 Release Candidate on your iPhone/iPad by navigating to Settings -> General -> Software Update. The update will only show up on your iPhone or iPad if the developer beta profile is installed. If you are in the public beta channel, you should get the update within the next 24 hours.
Alongside iOS 15.4 RC, Apple also seeded the Release Candidate of macOS Monterey 12.3, tvOS 15.4, and watchOS 8.5 to developers.
