iOS 13.2.2 is now rolling out on the iPhone and iPod users. This comes after the release of iOS 13.2 last week. iOS 13.2.2 includes a patch for RAM management, cellular data performance, and so on.
If you wonder what happened to iOS 13.2.1, Apple released it last week exclusively for the HomePod. The first HomePod 13.2 update led some people to experience HomePod in brick, and Apple released iOS 13.2.1 to address these issues for HomePod owners.
The most significant change in iOS 13.2.2 is a fix for background applications and multitasking issues. This RAM management issue caused applications to crash when running in the background, significantly hampering performance and multitasking.
