Apple has started rolling out the update to its operating system. At the iPhone level, iOS 16.3 offers improvements and new features as well as the correction of certain bugs.
New in iOS 16.3 is end-to-end encryption of iCloud data, which is much more secure.
iOS 16.3 also benefits from a new system allowing you to identify yourself on an Apple account with a second authentication physical key. This system allows two-factor authentication via an external hardware key and not from the device.
Apple ID Security Keys allow users to increase the security of their account by requiring the use of a physical security key as part of the two-factor authentication process on new devices.
The latest update improves some features such as emergency calls which were too easily triggered before; It is now necessary to hold the side button with the volume up or down button, then release it to contact the emergency services.
Regarding the satellite emergency SOS functionality, which is only compatible with the new iPhone 14 range can be issued more simply with a press of the side and volume buttons. A countdown is then activated before sending the SOS directly.
Other minor software issues have been fixed to provide more security and smoothness.
iOS 16.3 is compatible with iPhone 8 and 8 Plus, iPhone 8, iPhone X, XR, XS Max, XS, 11, 11 Pro and Max, iPhone SE, iPhone 12, 12 mini, 12 Pro and 12 Pro Max, iPhone 13 and iPhone 14.
To perform the update, go to Settings > General > Software Update to trigger the download and installation.
