Apple has made iOS 11.0.2 available on supported iPhones, iPads and iPods. It's the second update since the launch of iOS 11 on September 19. Like 11.0.1, it aims to fix some problems that users have complained about. Among them is the iPhone 8 crackling audio problem. If that's something you've been experiencing, you can download the update now.

iPhone 8 and iPhone 8 Plus owners had taken to forums and social media to report a crackling noise when making phone calls over cellular networks. Apple acknowledged the issue when it came up and promised a fix in "an upcoming software release." Now it's here.

I didn't have the crackling audio problem on my iPhone 8 unit, so I haven't been able to test if the update is effective. But if the patch does fix the issue, that's a relief, as some users were concerned it was a problem with their hardware rather than the software.

Apple listed two other fixes in iOS 11.0.2's release notes. The company says that "an issue that could cause some photos to be hidden" has been fixed, as well as "an issue where attachments in S/MIME encrypted emails would not open." Last week's iOS 11.0.1 update fixed the widespread Exchange e-mail server problem.

As we said when iOS 11 was released, it's sometimes best to hold off on updating to new versions of your hardware's operating system until a few bugs have been addressed.
