Apple has released iOS 11.3.1 for the iPhone, iPad and iPod Touch. The update fixes an issue on some iPhone 8 with non-Apple replacements screens. The update is nearly 47.5 MB in size, though this could be higher depending on whether you’ve downloaded the previous updates or not. You can download the update by going to Settings>General>Software update on your iOS device or through iTunes.
The primary focus on the latest software update is to fix an issue where touch input wouldn’t work on the iPhone 8 that were serviced with “non-genuine replacement displays”. As Apple explains in its release notes for the software, the update “addresses an issue where touch input was unresponsive on some iPhone 8 device because they were serviced with non-genuine replacement displays.”

Apple has, however, reiterated that consumers should not go to third-party vendors for screen repairs and instead visit Apple for genuine displays. “Non-genuine replacement displays may have compromised visual quality and may fail to work properly. Apple-certified screen repairs are performed by trusted experts who use genuine Apple parts”, the iOS 11.3.1 note continues.
This issue was first reported by Motherboard last week, when some iPhone 8 handsets with third-party replacement displays became unresponsive to touch-based inputs. This is the not the first time an issue like this has affected Apple iPhones. Last year, a similar issue was identified where Touch ID would stop working on the iPhone 7, if the screen was replaced by a third-party vendor.
