Apple sends out iOS 12.3.2 to just one iPhone model to fix just one bug
Apple released iOS 12.3.2 today, and the update appears to have been disseminated with a particular bug extermination in mind. Apparently, this build of iOS was disseminated to fix an issue that iPhone 8 Plus users have been having with the Portrait mode depth effects. More specifically, Apple says that "iOS 12.3.2 resolves an issue that could cause (the) Camera to capture Portrait mode photos without depth effect on some iPhone 8 Plus devices."
Because the update was pushed out to take care of this issue, it is only available for 2017's iPhone 8 Plus. Other models from the iPhone 5s to the 2018 iPhone models were last updated with iOS 12.3.1. Considering that Apple has promoted the Portrait mode's variable bokeh or blur effect as a major feature on the iPhone 7 Plus, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, and iPhone XR, the company must have worked quickly to push out the update as fast as possible.
If you have the Apple iPhone 8 Plus, you can coax the update out by going to Settings > General > Software Update and tapping on "Download and Install" on the bottom of the screen. Make sure that your batteries are fully charged first, and to save on data usage you might want to be connected to a Wi-Fi network.
Just last week, Apple unveiled iOS 13, which will be released in September. Arguably the major new feature is the system-wide dark mode, although shrinking app downloads by 50% and updates by 60% are something that iPhone users should be looking forward to as well. And app load times are going to be reduced by as much as two times. The iOS 13 update will be available for the iPhone 6s and up.
Apple introduced the Portrait mode on the iPhone 7 Plus, the first iPhone to feature a dual camera setup.
