Apple has rolled out a surprise iOS 17.3.1 update focused on fixing an annoying text overlap bug introduced in the previous iOS 17.3 update. This incremental update is available over-the-air for iPhones already running iOS 17 public builds.
The text overlap issue has been frequently reported by users after updating their iPhones to iOS 17.3. It caused text from different apps to overlap and clutter the screen. This visual bug made reading text very difficult.
It seems like Apple is quickly resolving this serious usability problem before the public launch of iOS 17.4. Users had been complaining about the text overlap on social media and Apple support forums ever since iOS 17.3 was rolled out.
What’s New in iOS 17.3.1?
According to the release notes, iOS 17.3.1 specifically targets the text overlap bug plaguing iOS 17.3. It prevents text from different sources from incorrectly overlaying on top of each other on the screen.
Apart from addressing the text overlap issue, this update also includes unspecified bug fixes and security enhancements. However, no other major changes or new features are expected.
The build number for this update is 21D61, which is also assigned to the corresponding iPadOS 17.3.1 version.
Should You Update to iOS 17.3.1?
All iPhone users on iOS 17.3 or earlier public builds should install the 17.3.1 update immediately. It resolves the frustrating text overlap problem that has persisted since the last major 17.3 release. Updating provides a smoother user experience.
However, iOS 17.4 beta testers cannot downgrade to 17.3.1. The update is only available for public iOS versions preceding 17.4.
To check for and download the iOS 17.3.1 update OTA, navigate to Settings > General > Software Update, and then tap Download and Install. Make sure your iPhone is charged above 50% before installing. Also, take a backup beforehand.
This surprise incremental update right before the iOS 17.4 launch ensures iPhones get critical bug fixes as soon as possible. Apple aims to keep issues from impacting users for prolonged periods.
