Today Apple released small software updates for iPhones, iPads and Macs: iOS 11.3.1 for mobile devices, and a Security update for the already released macOS 10.13.4 for Macs.

At just over 49 megabytes, iOS 11.3.1 is a small update that fixes iPhone 8s for users whose touchscreens have stopped responding with aftermarket replacement displays. iOS 1

1.3 caused iPhones managed by external vendors to have this problem. The users expressed their frustration that Apple punished them for failing to carry out the company's repair process.

The following patch notes contain an Apple warning to stay away from "non-original backup ads". Apple's value proposition has always been about total control of the hardware to ensure a smooth experience. The company took advantage of these update notes to reiterate that the company can not assume that it supports the work of other companies.

Despite Apple's long-standing attitude not to support problems in these cases, the update has claimed, however, to fix the problem. Here are these update notes:

iOS 11.3.1 improves the security of your iPhone or iPad and fixes an issue where touch input on some iPhone 8 devices may become unresponsive because they were served with non-original replacement displays.

Note: Non-original replacement displays may have degraded visual quality and may not function properly. Apple certified screen repairs are performed by trusted experts using genuine Apple parts. For more information, visit support.apple.com
