Apple has released the second update to iOS 11 since the software went public on September 19 for all iPhone and iPad users. The latest iOS 11.0.2 OTA update fixes the iPhone 8 crackling sound problem

Owners of the Apple iPhone 8 and iPhone 8 Plus are reporting a strange squeak when making a phone call or a facetime call. Apple has acknowledged the problem and promised to fix it with a software upgrade. iOS 11.0.2 is that update and it is available for download on iPhone 5s and later, iPad Air and later and iPod touch 6th generation. However, users should keep in mind that the update is being rolled out periodically and may not be available for download on all devices at this time. It usually takes one or more years for iOS updates to arrive on all devices after Apple starts rolling them out.

In addition to resolving the iPhone crackling sound issue, the second iOS 11 update fixes an issue that could hide some photos and fixes an issue where S / MIME encrypted email attachments won’t open.

Last week, Apple released the first update to iOS 11, fixing a critical Outlook and Exchange Email issue. Some users have reported that they are unable to send emails using a Microsoft account on their iOS device. Apple has fixed the issue with the iOS 11.0.1 update.

To update to iOS 11.0.2, make sure your device is connected to Wi-Fi and has a power outlet for charging. Tap Settings> General> Software update. Tap Download and Install to get updates. If a message temporarily asks apps to remove because more updates are needed for iOS updates, tap Continue or Cancel. Later, iOS will reinstall the removed apps.
