Apple's iOS 13 had a rocky start ever since its release in September and this iOS version is still very buggy.
This is the update to the iOS 13.2 build that was rolled out on October 28. The update fixes a major memory management issue that we told you about the other day that caused apps open in the background to close. The most recent update contains minor changes focused on improvements in performance as well as bug fixes on issues that OS 13.2 was not able to resolve. If you didn't already upgrade to iOS 13.2, now's the time. with the disclaimer that iOS 13.3 is already in developer beta, so it'll probably land before too long. A doozie that now requires 13.2.2 to emerge today and heroically save the day and crush yet more bugs. It turns out that some encrypted email messages between Exchange accounts were unreadable.
The update also takes care of the a problem that caused iPhone users to lose cellular service following a call and also exterminates a bug that prevented iPhone users from accessing mobile data.
Additionally, there is a fix for the issue which affected connectivity with YubiKey Lighting-powered accessories. The same fix is available for iPadOS 13.2.2.
iOS 13.2.2 includes bug fixes and improvements for your iPhone. When iOS 13.2 was introduced, scores of users began complaining that apps running the background on their iPhones would reset when returned to via the app switcher.
