iOS 16.4 includes additional Crash Detection optimizations for all iPhone 14 and iPhone 14 Pro models, according to Apple's release notes for the software update, which is expected to be released to the public as early as next week.
Apple does not provide any specific details about the optimizations, but the company has been working to improve Crash Detection after emergency dispatchers in several U.S. states and Canada complained about the feature triggering an influx of false 911 calls from skiers and snowboarders throughout the winter. This is the third update with Crash Detection optimizations after iOS 16.1.2 in November and iOS 16.3.1 last month.
Crash Detection launched last year for all iPhone 14 models and the latest Apple Watch models. The feature is designed to detect a severe car crash and automatically call emergency services if a user does not respond to the device within 20 seconds, but has sometimes mistaken a skier or snowboarder falling down as a car crash, according to reports out of Colorado, Utah, New York, Pennsylvania, Minnesota, and other popular skiing areas.
It's unclear if the latest optimizations will fully resolve the issue. The skiing season is drawing to a close in the U.S. and Canada, so we will have to wait until next winter in order to know if iOS 16.4 leads to a reduction in false 911 calls.
