iOS 12.3.1 update has been released by the Apple to fix bugs and issues for iPhone and iPad. The new update has come within two weeks of the company releasing iOS 12.3 update, which included a brand new Apple TV app and support for AirPlay 2-enabled TVs, apart from its own bunch of bug fixes and improvements.

Apple has reportedly updated its "iPhone User Guide" for the upcoming release of iOS 12.1, indicating that the latest version of the mobile operating system (OS) will include Group FaceTime and dual-SIM support for its newly-launched iPhones.

Even though Apple's first update to iOS 12 has cured the iPhone charging problem, iOS version 12.0.1 is causing users to complain about frequently broken calls, network and signal connectivity problems and battery life issues, the media reported.

Apple is all set to roll out the latest iOS 12 update tonight; the same will be available for general public to download from today onwards. The new iOS version is a mobile operating system designed for iPhone, iPad and iPod Touch devices.

Apple planted the third developer beta of iOS 12 to all eligible devices, ranging from iPhone 5s to the iPhone X. And now, two weeks after the second beta, iOS 12 beta 3 is here to amuse us. Hopefully, we’ll see some useful bug fixes and stability improvements as well as the first roll out of Apple’s in-house mapping data for the Bay Area in Maps.
