Apple today stopped validating iOS 16.1.2 after releasing iOS 16.2 last week. This means that users who updated to iOS 16.2 can no longer downgrade to an earlier version of iOS.
iOS 16.2 introduces the “Wu Bian Ji” app, and also adds Apple Music singing, lock screen improvements, and other features and bug fixes to the iPhone.
Apple usually stops validating older versions of iOS within a few weeks of pushing an official update. For some users who have updated to the latest iOS system, when they encounter major bugs, the way of downgrading is sometimes very effective.
This is why Apple waits a while before closing the verification channel for older versions of iOS. The previously released iOS 16.1.2 improves the reliability of the car crash detection feature for iPhone 14 and iPhone 14 Pro users, improves compatibility with wireless carriers, and brings important security patches.
