The stock Camera autofocus problem was occurring mostly for users of the iPhone X and iPhone 8 Plus terminals, two flagships that include a dual lens hardware setup. The bug prevented the camera to focus properly when the user attempts to capture a photo. It either shifted between the two lenses or simply didn’t focus at all!
Fact: Basic troubleshooting tips like force restarting the iPhone X, or tweaking the Camera app settings did not have any positive effect. The only temporary fix, before this update was the option to downgrade iOS 11.2 to iOS 11.1.2.
