How to Fix Camera Focus Issue on iPhone X, iPhone 8 and 8 Plus
You can fix the camera focus issue on your iPhone by either updating the device or downgrading it to the previous iOS version. Since Apple has released iOS 11.2.1 with the permanent fix to the ongoing problem, I would recommend you to update your iPhone to the latest iOS version instead of downgrading it. Before updating your device, make sure it’s at least 50% charged and has the proper Wi-Fi connection. Step #1. Launch Settings app on your iPhone. Step #2. Now, you need to tap on General. Step #3. Next, tap on Software Update. Step #4. Finally, tap on Download and Install. That’s it! Now, let your device be successfully updated. Once it’s done, you can use Camera app without any issue. Wrapping up: Apart from fixing the auto focus issue, iOS 11.2.1 has also fixed a major HomeKit vulnerability that disabled remote access for shared users of the Home app. So, if you are facing this issue on your iOS device, update it.
