After the report of iOS 11.3 coming with issues that makes touch functionality of some iPhone unresponsive, Apple has released iOS 11.3.1 that doesn’t bring any fresh features but addresses the issue.
The new iOS update is available for download for all compatible iPhone, iPad, and iPod touch models.
The iOS 11.3.1 update is nowhere as major a software build as the iOS 11.3 package that was designed to enhance the user experience by letting users toggle performance throttling and view battery health.
However, it is an important update if you own an iPhone 8 that has been serviced with a third-party display panel. The update fixes the bug that was making some non-genuine iPhone 8 displays unresponsive after installing the iOS 11.3 update.
The bug wasn’t revealed officially, but some affected users reported its existence weeks after the release of the iOS 11.3 update. The iOS 11.3.1 update additionally improves the security of iPhone and iPad devices. Details about the security content can be viewed by visiting the official support page.
You can download the iOS 11.3.1 update on iPhone 5s and above models, iPad Air and above models, iPad mini 2 and above models, and the sixth generation iPod touch. To download, go to Settings > General > Software Update and then follow the on-screen instructions.
You are advised to use a Wi-Fi connection to download the over-the-air (OTA) update. Also, it is recommended to back up your data before beginning the update process.
