This means that iPhone and iPad users will not be able to upgrade to the iOS 18.3.2 operating system after upgrading their devices to a new version.
iOS 18.4 was released on March 31. This is a major update as it brings Apple Intelligence support in more languages. In addition, the update adds a series of new emojis,priority Notifications, and visual Intelligence technology exclusively for iPhone 15 Pro models.
Notably, iOS 18.4 also comes with a series of important security patches, including serious errors that allow the application to access users' sensitive data.
Previously, iOS 18.3.2 was released on March 11 with the goal of fixing a vulnerability that allowed malicious web content to break down sandbox protection mechanisms, posing a great risk to information security.
Apple regularly blocks upgrades to older iOS versions to encourage users to update software and protect their devices from cyber attacks. However, this move also makes it difficult for some users to make mistakes when using the new iOS version, because they cannot go back to the previous version.
Currently, the only downside option is from iOS 18.5 beta to iOS 18.4. Compatible iPhone and iPad users should check and update to iOS by accessing Settings > General Settings > Software Update.
