1 A lot of Bug Fixes
As you might expect, the update also addresses a number of bugs and issues found in previous iOS 12 versions. Specifically, Apple has patched a bug that caused Face ID to become temporarily unavailable as well as an issue that prevented Visual Voicemail from working.
It also addresses a time zone update bug, a predictive text issue for Chinese and Japanese in Messages, and an issue that could prevent some Voice Memos from uploading to iCloud properly.
While it’s an iOS update, iOS 12.1.1 also adds features and fixes to HomePod — including support for the smart speaker in Mainland China and Hong Kong, and illuminated LEDs during Group FaceTime audio calls.
iOS 12.1.1 should now be available to all iOS users as a free over-the-air download. You can find it in Settings > General > Software Update.
