IOS 12.3.1 Release – Upgrade Recommended
IOS 12.3.1 was released on May 24 only a few days after the release of IOS 12.3. Upgrade to this version is recommended for Senior Tech Club members and fans.
You have to presume that this quick release was to fix bugs that came up and does not include new functions. The documentation from Apple proposes that the update fixes bugs with the Messages app and the Phone app.
I upgraded my iPhone on May 29 with no issues. The upgrade took 12 minutes.
