Apple has released iOS 12.3.1 for iPhone and iPad. This is a bug fix release that patches issues pertaining to VoLTE and iMessage. The update is relatively minor as it does not include any new features or functions that would usually accompany a more significant update.
The change log of the update is:
- 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
Apple had released iOS 12.3 a week back which brought in Apple TV and the 12.4 developer beta is still in the works which is implementing Apple Card in the Wallet app.
The WWDC is on June 3 where Apple will be releasing iOS 13 and more.
