Apple Releases iOS 16.1.2 With Carrier Improvements and Crash Detection Optimizations

by

Apple today released iOS 16.1.2, another minor bug fix update that comes one week after the release of iOS 16.1.1 and three weeks after the launch of iOS 16.1, an update that added support for iCloud Shared Photo Library, Matter, Live Activities, and more.

iOS 16
The iOS 16.1.2 update can be downloaded on eligible iPhones over-the-air by going to Settings > General > Software Update.

According to Apple's release notes, the iOS 16.1.2 update introduces improved compatibility with wireless carriers along with Crash Detection optimization on the iPhone 14 and iPhone 14 Pro models. Apple's full release notes are below:

This update provides important security updates and the following enhancements for your iPhone:

- Improved compatibility with wireless carriers
- Crash Detection optimizations on iPhone 14 and iPhone 14 Pro models

Crash Detection optimization could perhaps involve improvements to prevent the iPhone 14 models from calling emergency services when users are enjoying rollercoasters and other intense rides. There have been multiple reports of accidental Crash Detection activations at amusement parks.

iOS 16.1.2 will be followed by iOS 16.2, an update that is being beta tested and is expected to see a launch in December. iOS 16.2 introduces the Freeform app, new Home app architecture, and other features.

Forgive my ignorance but what do they mean by "wireless" carriers? Aren't all of them wireless? No one plugs their iPhone in to get signal.

FYI. After updating, you might be forced to go through a SOS tutorial. You will have a forced red badge on your settings icon. When you go in there will be a notification to tap on. If you tap back out it's still there. You are forced to tap "learn more" and forced to go through the process even though you have been familiar with everything there for a long time, except for the satellite stuff. And then the nagging will disappear. I know that some people sometimes get a buggy situation where the nagging will remain even after you have gone through everything Apple forces you to look at, so good luck.

Improved compatability? Too bad this doesn't add 3.45 GHz 5G support on AT&T for iPhone 12 and 13 models...
