On Monday, February 4, Apple released the second developer beta for iOS 12.2. The update includes fixes for users using iOS 12.2 Beta 1. Developers should therefore be urged to update their iPhone as soon as the software is available. It is currently unclear whether the update contains an update to the Group FaceTime error that was discovered last week.
Apple has not yet listed the release notes for iOS 12.2 dev beta 2 on its Web site, but the fix contains an update number of fixes. Although it does not appear to include any new or noteworthy features of dev beta 1, users should notice a more stable version of iOS.
Release notes, if available, are listed here.
