Apple has just released iOS 12.1.3, the fifth update to the iOS 12 operating system since its September launch. iOS 12.1.3 is a minor update that follows iOS 12.1.2 (iPhone only), released back in December, and iOS 12.1.1, also released in December. 

The iOS 12.1.3 update will be available on all eligible devices over-the-air in the Settings app. To access the update, go to Settings > General > Software Update. As with all iOS updates, iOS 12.1.3 will be free to download. iPhone owners will be upgrading to iOS 12.1.3 from iOS 12.1.2, while iPad owners will be updating from iOS 12.1.1. 

iOS 12.1.3 is a minor update, and during the beta testing period, we found no major new features. According to Apple's release notes, iOS 12.1.3 includes fixes for multiple bugs affecting iPad Pro, HomePod, CarPlay, and more. 

On HomePod, the update fixes bugs that could cause restarts or that could cause Siri to stop listening. On the iPad Pro, iOS 12.1.3 fixes an issue that could cause audio distortion when using external input devices, and for CarPlay, issues that could cause disconnects from the 2019 iPhones have been addressed.
