Apple on Thursday released a new version of iOS 12.1.2 for the iPhone. The new release’s build number is “16C104,” up from the “16C101” build number used for the Monday release.
It isn’t known for sure why Apple released a second version of iOS 12.1.2, but it is likely intended for those devices that haven’t had the update already installed. It could contain minor bug fixes or tweaks, not significant enough for another version bump.
The iOS 12.1.2 update is available only on the iPhone over-the-air in the Settings app. To install the update, go to “Settings” -> “General” -> “Software Update” and follow the prompts. The update is free to download. If you installed iOS 12.1.2 earlier this week, you’ll likely not see this update as being available. (We don’t see it on out iPhone XS Max.)
The iOS 12.1.2 update from earlier this week included the following:
- Fixes bugs with eSIM activation for iPhone XR, iPhone XS, and iPhone XS Max
- Addresses an issue that could affect cellular connectivity in Turkey for iPhone XR, iPhone XS, and iPhone XS Max
