Fault detection and wireless compatibility


Apple released iOS 16.1.2 update on Wednesday, which came with several fixes and updates, including crash detection improvements and wireless compatibility optimizations. The update comes three weeks after the release of iOS 16.1.1 and more than a month after the release of iOS 16.1. This iOS update includes improved security, improved compatibility with wireless carriers, and improved crash detection for the iPhone 14 line.

The new Apple iOS 16.1.2 is available for all devices compatible with iOS 16, namely iPhone 8/iPhone X and newer. iOS 16 ended support for the iPhone 6S and 7, as well as the iPod Touch. There is no iPadOS 16.1.2 update. Given Apple’s confirmation of automatic update delays, the update can be triggered manually by going to Settings > General > Software Update. If you are using a newer beta version of the software, you should unregister the device until the update appears.

After the release of this update, there were isolated reports of issues with Bluetooth headset search, cellular connectivity, and volume control. No new widespread bugs have been reported at this stage. However, the biggest disappointment of iOS 16.1.2 is the limited scope. The list of iOS 16 bugs remains, and users continue to express their frustration that update after update hasn’t fixed them. iOS 16.1.2 continues this well-worn theme again.

Improved wireless carrier compatibility is not a one-size-fits-all feature, and everyone is still trying to figure out what Apple means by that. Apple offers no further explanation, and it doesn’t address the iPhone’s 5G support in India, which will arrive in iOS 16.2 (details in the Road Ahead section below). Some performance issues have been reported, but we don’t currently know which carriers or countries will benefit from the changes.

Crash detection optimization for the iPhone is long overdue. The feature, which was itself a catch-up to the Car Accident Detection feature available on Android since 2019, made headlines for launching on roller coasters, ski slopes, and more.

Other than Apple, most expected security optimizations official security page doesn’t yet list any security fixes for iOS 16.1.2, but teases “details coming soon.” I will update this section as soon as this information is published.

While operator improvements remain a mystery, the improvements in failure detection are critical and should reduce the number of false emergency calls. For anyone still on the fence about whether or not they should upgrade, I highly recommend doing so.

iOS 16.2 is a popular target for many iPhone owners still running iOS 15, but Apple’s feature releases often contain more bugs than smaller updates. So it would be helpful if iOS 16.1.2 was a (relatively) reliable stepping stone.

Apple iOS 16.2 is now in Beta 4, and the feature-focused release includes a slew of new features, such as the Freeform collaborative whiteboard app and a new Home app architecture.

iOS 16.2 also adds support for Apple’s new Rapid Security Response feature. This allows you to install security patches on iPhone and iPad regardless of new iOS versions. Android has been working this way for some time and releases monthly security patches. Join the Apple Beta Software Program if you want to try iOS 16.2 before it launches in late December.
