CTOnews.com, February 1 (Xinhua)-- after the release of the official version of iOS 16.3 last week (January 24), Apple today stopped testing iOS 16.2, the previously available version of iOS. This means that users who update to iOS 16.3 can no longer be downgraded to earlier versions of the iOS system.

IOS 16.3 introduces iCloud advanced data protection, Apple ID security keys, and other enhancements to iPhone, bug fixes, and security updates.

Apple usually stops validating older versions of the iOS within weeks of pushing the official update. For some users who update to the latest iOS system, downgrading can sometimes be very effective when they encounter a major Bug. That's why Apple will wait a while before shutting down the authentication channel for the old iOS system.

CTOnews.com learned that the previously released iOS 16. 2 introduced the "boundless" App and added Apple Music singing, lock screen improvements, and other features and bug fixes to iPhone.
