Today iOS 12.3.1 was released for iPhone, iPad, and iPod Touch. This comes just a little over a week since iOS 12.3 was released. The problems identified are not widespread issues, but I’m sure people who were having trouble using their iPhones as a phone will appreciate this patch. Even if you don’t experience these issues I recommend installing the update to prevent these issues in the future, and because there are undisclosed security fixes included.
iOS 12.3.1 includes bug fixes for your iPhone and iPad. This update:
– Fixes an issue that could prevent making or receiving VoLTE calls
– Fixes issues in Messages that could cause messages from unknown senders to appear in your conversation list even though Filter Unknown Senders is enabled
– Fixes an issue that could prevent the Report Junk link from appearing in Messages threads from unknown senders
To update your device go to the Settings app > General > Software Update.
