If you’ve upgraded to iOS 13.6, there’s no going back! That’s because Apple has stopped signing iOS 13.5.1. This means that it’s no longer possible to download and install it on your device.
iOS 13.6 added audio versions of key stories from Apple News+, along with a new daily audio show called Apple News Today, available in the free version of the Apple News app. In addition, it introduced a new symptom-tracking feature to the Health app, plus a feature that lets you use your iPhone as a car key.
By stopping user from reinstalling older versions of iOS, Apple makes sure that as many customers as possible are using the latest, most stable experience currently available. While iOS updates include big marquee features like the ones listed above, they also contain all-important bug fixes. These plug security vulnerabilities that have been discovered, among other things.
Apple introduced iOS 13.6 on July 15. If you haven’t upgraded yet, you can find all the details about its features here.
