iOS 11.3.1 Update Released for iPhone and iPad, Download Now
Apple has released iOS 11.3.1 for iPhone and iPad users. The update is said to include some security updates, and also resolves a problem that caused some iPhone devices with repaired screens to not work as intended.
The security updates make the iOS 11.3.1 update relevant to all iPhone and iPad users with devices running a prior iOS build. The unresponsive screen issue is apparently limited to select iPhone 8 models that were repaired using third-party components, emphasizing why it’s important to repair a broken iPhone screen through Apple or an Apple authorized repair center.
Separately, Apple has released Security Update 2018-001 for MacOS High Sierra, and Safari 11.1 for Mac OS El Capitan, Sierra, and High Sierra.
