The latest version of iOS 11.3.1 includes a fix for an issue where people who use third-party repair services to replace their displays had their devices become unresponsive. According to release notes, "iOS 11.3.1 improves the security of your iPhone or iPad and addresses an issue where touch input was unresponsive on some iPhone 8 devices because they were serviced with non-genuine replacement displays." Gizmodo reports: Retailers and customers alike suspected that Apple was deliberately letting the issue and other malfunctions that arose from replacing other components go unresolved in some sort of ploy to pressure customers into paying for officially licensed repair services that are more expensive. It's possible that some users indeed were forced to shell out a fair chunk of change to Apple for official repairs, in which case they might justifiably be angry that this was an issue that could be resolved with an update. iOS 11 was notoriously buggy after its release, and Apple has devoted so much effort to bug-fixing that this year's iOS 12 update will reportedly have fewer new features. Though Apple says the 11.3.1 fix will work, it also warned people to please not use third-party repair shops: "Note: Non-genuine replacement displays may have compromised visual quality and may fail to work correctly. Apple-certified screen repairs are performed by trusted experts who use genuine Apple parts. See support.apple.com for more information."
