Apple has released iOS 13.4.1 and iPadOS 13.4.1 following the iOS 13.4 and iPadOS 13.4 rollout two weeks ago. The updates are minor and include bug fixes.
The iOS 13.4.1 software update fixes an issue that prevented devices running iOS 13.4 from participating in FaceTime calls with devices running iOS 9.3.6 and earlier or OS X El Capitan 10.11.6 and earlier. It also addresses an issue that caused Bluetooth to fail when used from the quick actions menu on the Home screen.
In addition to above two fixes, there’s a third addition to the iPadOS 13.4.1 release notes. It fixes a bug related to the Flashlight on the new iPad Pro models. Both 11-inch and 12.9-inch iPad Pro devices couldn’t toggle the Flashlight from Control Center or the Lock screen in iOS 13.4, which now stands resolved in iPadOS 13.4.1.
The iOS 13.4.1 and iPadOS 13.4.1 software updates are available to download on all eligible devices over-the-air. Simply head over to Settings > General > Software Update and you’re good to go.
