Apple releases iOS 15.3.1 with security and Accessibility fixes

Two weeks after the release of iOS 15.3, Apple is now rolling out iOS 15.3.1 and iPadOS 15.3.1 to iPhone and iPad users. Apple says this update includes security fixes as well as a fix for a bug impacting Braille displays. Head below for the details.

iOS 15.3.1 now available

You can update your iPhone to iOS 15.3.1 by heading to the Settings app, choosing General, then choosing Software Update. The build number for today’s update is 19D52. The update is available to those users running the public release of iOS 15.3, not anyone running the iOS 15.4 beta.

Here are the specific details on the security fix:


Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)

In addition to iOS 15.3.1, Apple is also rolling out the following updates:

  • iPadOS 15.3.1
  • watchOS 8.4.2
  • macOS Monterey 12.2.1

iOS 15.3 was released to all iPhone users last month with a handful of performance fixes and security fixes. One of the most notable changes here was a fix for a Safari vulnerability that may have been leaking your browsing history and Google ID data to the websites you visited. Today’s update further refines the experience with additional improvements.
