1 Bug Fixes and Improvements
As usual, iOS 12.1 also features a number of under-the-hood changes, bug fixes, and security vulnerability patches. If you skipped iOS 12.0.1 you should know that iOS 12.1 addresses the slow Wi-Fi issue and the bug behind the “Chargegate” controversy.
iOS 12.1 should now be available as a free over-the-air update for users with compatible devices. You can find it in Settings > General > Software Update.
