iOS 11.2.1 Fixes iPhone X / 8 Autofocus Camera Issue Introduced With iOS 11.2
In addition to fixing the nasty 0-day exploit which existed in Apple’s HomeKit protocol, the release of iOS 11.2.1 seems to also fix some niggling autofocus issues which certain iPhone X, iPhone 8, and iPhone 8 Plus began experiencing with the installation of iOS 11.2.
The experienced autofocus issue doesn’t appear to have been affecting every single iPhone X, iPhone 8, and iPhone 8 Plus user, but was affecting enough device owners for the social media and forum chatter to begin, with individuals bouncing ideas off each other as to why the problem was happening.
For those who were affected, the issue manifested itself by rendering users unable to focus properly when attempting to capture a photograph in various different camera modes. Different device owners were experiencing different behavior with some suggesting the dual-camera systems were simply flicking between the two available lenses.
Some of those users took to various forums to give an insight into the problem and the processes that they had gone through to try and diagnose and resolve the problem. One user was able to track the issue down to the installation of iOS 11.2 by rolling back the firmware to iOS 11.1.2, made possible by the fact that Apple is still digitally signing that firmware version.
The autofocus bug immediately disappeared but came back as soon as the device was upgraded back to iOS 11.2. That user was immediately able to diagnose the issue as being software related, and, more specifically, introduced with the release of iOS 11.2.
With iOS 11.2.1, Apple seems to have fixed the problem, either purposely or inadvertently. Installing Apple’s latest iOS release on iPhone X, iPhone 8, and iPhone 8 Plus means that the autofocus issue should no longer be present, but, perhaps more importantly, full functionality has been restored to HomeKit and there is no longer a critical bug in the system that users need to worry about when using HomeKit-enabled hardware in the home. That latest version of iOS is available to download right now for compatible devices through the Software Update mechanism in iOS.
Alternatively, if you are a jailbreak fan, and are exciting about the potential of an iOS 11.1.2 jailbreak, then downgrading to iOS 11.1.2 will also solve both of those problems as they were uniquely introduced with iOS 11.2.
