Apple has just released iOS 11.0.2 for iPhone and iPads. As noted in the update notes seen below, the update:
- Fixes an issue where crackling sounds may occur during calls for a small number of iPhone 8 and 8 Plus devices
- Addresses an issue that could cause some photos to become hidden
- Fixes an issue where attachments in S/MIME encrypted emails would not open
Personally, I'm hoping it resolves the issue I keep having with using Personal Hotspot...
