Apple Releases iOS 11.2.1 With Bug Fixes [Update]


iOS 11

Following the public launch of iOS 11.2 earlier this month, Apple has now released a minor update to the mobile operating system.

Today, Apple officially launched iOS 11.2.1 to the public. As the number system indicates, this is a minor update, with a primary focus on bug fixes and performance enhancements across the board. This is a free update, as is par for the course, and it can be downloaded and installed beginning right now on supported devices.

To update, open Settings –> General –> Software Update. From there, follow the on-screen instructions and complete the process.

The biggest part of the update is a fix for an issue that could cause remote access to HomeKit shared users to not be accessible from the Home app. While fixing a recently discovered vulnerability, Apple broke this particular feature, so iOS 11.2.1 will bring it back to life for HomeKit users. As a refresher, the HomeKit vulnerability discovered earlier this month made it possible for unauthorized access to smart, connected devices, including smart locks designed for doors in a home. Apple fixed the problem on the server-side, which patched the issue since it wasn’t tied to HomeKit hardware or specific devices. However, it required Apple to disable remote access for shared users at the time. Apple said that it would be bringing the feature back online this week.

The update also includes fixes for other bugs that have been discovered since the public launch of iOS 11.2, as well as performance tweaks and improvements behind-the-scenes.

iOS 11.2.1 measures in at 68.7MB. It is available now.

Update 1

iOS 11.2.1 fixes the autofocus bug on iPhone X and iPhone 8, which affected some users after upgrading to iOS 11.2.

Update 2

You can install the iOS 11.2.1 update wirelessly, but if you’re not getting the OTA update then you can find the direct links to download iOS 11.2.1 firmware (IPSW) files for iPhone, iPad and iPod touch so that you can update it manually using iTunes.
