Apple rolls out iOS 12.4 update that fixes security issues and brings iPhone migration for data transfer.

Apple has released the new iOS 12.4 stable update, which will likely be the final iOS 12 update, given iOS 13 is already in public beta now. Released two months after the last iOS 12.3.1 update, the new one introduces an iPhone migration feature that can be used to directly transfer data from an old iPhone to a new one.

Other than the iPhone migration tool, the iOS 12.4 update doesn’t add much, but focuses on bug fixes and security issues. It re-enables Walkie-Talkie functionality, and includes a security fix for the Walkie-Talkie app on Apple Watch as well. Apple had disabled the Walkie-Talkie feature on Apple Watches after a security issue, which allowed iPhone users to overhear conversations.

The changelog of the update mentions that it has enabled FaceTime video and audio calling for iPhone and iPad devices sold in Pakistan and also includes support for HomePod in Japan and Taiwan.
