iOS 11.3.1 and macOS High Sierra 10.13.1

Yesterday Apple released the newest update of iOS 11, iOS 11.3.1.

At just over 49 megabytes the minor update includes a major fix for iPhone 8 users who’s iPhones were left without touchscreen functionality due to aftermarket or third party screen replacement. This issue was caused by a bug found in iOS 11.3 which curiously enough only affected the iPhone 8 and aftermarket screen replacements, fortunately the issue has been resolved with the latest update.

Patch notes found in the update description show a distinct warning against going through third-partly repair systems, the exact reference stated to stay away from “non-genuine replacement displays.”

The main reason apple included this in the patch notes is a fairly simple reason, they value the ability to provide a smooth experience relying on genuine hardware, the use of third party displays could affect the users experience depending on compatibility and touch sensitivity. Apple made use of the patch notes to stress on the fact that they will not support screen or hardware issues if the user has decided to replace their screen with a “non-genuine replacement display”.

These are the exact patch notes found in the description of the iOS 11.3.1 update;


“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.

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.
