Apple has released iOS 16.3, adding support for Security Keys for Apple ID, a redesigned HomePod Handoff prompt, expanded availability of the iCloud Advanced Data Protection feature, changes to the Emergency SOS calling procedure, and more.
With the update, Apple has addressed a bug on the iPhone 14 Pro that could cause flashing horizontal lines to appear across the device’s display, something that many iPhone users reported seeing when their devices were being powered on.
The cause for the bug is unknown, but clearly the issue related to software rather than a fault with the display panel itself.
Available now over-the-air, Apple’s new iOS 16.3 update for iPhone can be downloaded by opening the Settings app, tapping General and selecting Software Update.
