Apple has released minor software updates for iPhones, iPads, and Macs addressing bugs and vulnerabilities. The new release includes a security update to the pre-existing macOS 10.13.4 and iOS 11.3.1 for mobile devices.
iOS 11.3.1: Fixes Unresponsive Touchscreen Issues in iPhone 8
Consuming over 49MB, iOS 11.3.1 is a minor update that fixes iPhone 8 handsets for the consumers who have touchscreen functionality issues. iOS 11.3 broke the touch functionality of iPhone 8 handsets’ screens that had had their original display replaced with third-party vendors. Apple includes a warning patch on the bottom to give a wide berth to “non-genuine replacement displays.” Apple’s sustainable value creation revolves around full hardware control to ensure a smooth user experience. However, the company stressing the updates notes states that it can’t be expected to support work done by third-party repairers.
“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”.
Despite the notes denying to support problems like these, the new update claims to fix the issue. Additionally, update iOS 11.3.1 improves the security of iPad and iPhone devices.
macOS 10.13.4 Update: Addresses Security Vulnerabilities
The macOS 10.13.4 version is a security update 2018-001. It does not add new functionality or features. It is designated to address two major security vulnerabilities. One of the issues was a memory corruption issue, addressed with better error handling. This could let an application gain elevated privileges. The other notable security issue was spoofing in the handling of URLs which was reportedly addressed with improved input validation. This might also result in UI spoofing by maliciously crafted text messages.
The updates are available for download on iOS 11 and macOS High Sierra supporting devices.
