iPhone 8 were affected that underwent a third-party display fix.
As per some reports from the web, the updated iOS version 11.3.1 fixes the unresponsive touch screen issue which the users experienced with third-party screen replacements. The bug wasn't revealed officially, but some affected users reported its existence weeks after the release of the update.
In addition to the major change, the update also brings various bug fixes and improvements.
Apple follows up its recent iOS 11.3 update with a new release targeting iPhone 8 devices with broken touch screens.
"Non-genuine replacement displays may have compromised visual quality and may fail to work correctly", it added. Apple-certified screen repairs are performed by trusted experts who use genuine parts. During the year 2017, an iOS update has also killed the touchscreen functions of the iPhone 7 and same happens in 2018 when the users of iPhone 8 models update with iOS 11.3. Details about the security content can be viewed by visiting the official support page.
Many engineers have speculated that the cause of most of Apple's errors surrounding third-party components is thanks to Apple restricting access to the special tool known as Horizon, that enables permissions to confirm on the device that the new parts belong to it. Apple, of course, fails to mention that Apple certified fix centres and replacement parts are not always easy to find.
