Less than two weeks after releasing iOS 12.3 to the public, Apple is following it up with another software update.
iOS 12.3.1 is now available for the iPhone, iPad, and iPod touch. You can download the update by going into Settings > General > Software Update on your iOS device or by plugging your phone or tablet into your computer and updating through iTunes.
The update to iOS 12.3.1 is a relatively minor one that's focused on bug fixes. According to Apple, iOS 12.3.1 fixes an issue that could prevent you from making or receiving VoLTE calls and fixes a Messages issue that could cause messages from unknown senders to appear in your conversation list even though you enabled Filer Unknown Senders. The update also fixes an issue that could prevent the Report Junk link from appearing in Messages threads from unknown senders.
If you've got an iOS 12 device, be sure to grab the update to iOS 12.3.1 to ensure that you're squashing your bugs and keeping your device up-to-date!
