Apple has released iOS 12.0.1, which fixes several bugs that affected users after upgrading to iOS 12.
One of the highest profile issues affected the iPhone XS, which sometimes failed to begin charging when connected to a Lightning cable. Other users reported that after the iOS 12 update, their iPhones would connect to WiFi networks at 2.4 GHz instead of 5.0 GHz even when both were available. Apple’s release notes say both issues have been fixed. The update also addresses a Bluetooth connectivity issue and a problem where subtitles sometimes didn’t appear in video apps.
iOS 12.0.1 includes a small design change on the iPad too. With the iOS 12 update, the ‘.?123’ key was moved. With version 12.0.1, that key has been restored to its previous position on the software keyboard.
