The other news of the iOS 16.4 and iPadOS 16.4 updates

The iOS 16.4 and iPadOS 16.4 updates also include the addition of 21 new emojis including animals, hand gestures and objects. Not only. Users will also receive notifications on their home screens related to web apps. With the update, the VoiceOver feature, used by those with visual impairments, provides an audible description of everything that appears on a user’s screen. And an accessibility setting will automatically dim video when your phone detects flashes of lights or strobes.

The update will bring bug fixes

One bug that users had encountered concerned the activation of Crash Detection from non-emergency impacts. The developers decided to remove this functionality.

Crash detection is triggered when sensors within a model of iPhone 14 series or a 2022 Apple Watch (series 8, Apple Watch Ultra and Apple Watch SE 2) detect a serious accident with a car, a pickup truck or SUV. If you don’t dismiss the alert within 10 seconds, your device will call 911 using an automated message that will include the location of the accident that occurred.

This feature made the sensors too sensitive and the decision to remove it was made following an event. During one weekend in December, the Summit County 911 Center in Colorado received 71 automated notifications in an area known for skiing. Skiers who had stopped quickly and fallen in the snow triggered the Crash Detection feature on their iPhone or Apple Watch, and none of the 71 crashes were caused by an actual emergency.

How to activate the update

When the update is ready to download and install, you can find it by going to Settings > General > Software Update.

With regard to iOS 17you should get a preview of the next iOS build during Apple’s WWDC developer conference, which is expected to kick off in early June.
