By going to the Settings app, selecting General, and then Software Update, you can update your iPhone to iOS 15.3.1. 19D52 is the build number for this update. Users who are running the public release of iOS 15.3, not the iOS 15.4 beta, are eligible for the update.
“iOS 15.3.1 provides important security updates for your iPhone and fixes an issue that may cause Braille displays to stop responding,” according to Apple’s release notes.
The following are the specifics of the update.
Last month, all iPhone users received iOS 15.3, which included a number of performance and security improvements. A fix for a Safari vulnerability that may have been leaking your browsing history and Google ID data to the websites you visited was one of the most notable changes here. The experience has been further refined with today’s update, which includes additional enhancements.
