Apple has released iOS 15.1.1, bringing improved call-drop performance for iPhone 12 and iPhone 13.
iOS 15.1.1 is aimed at iPhones 12 and 13 from 2020 and 2021. If you don’t have one of those phones, you won’t see (or need) this update.
iOS 15.1.1 will mean you don’t get call drop issues on your iPhone 12, 12 mini, 12 Pro, 12 Pro Max, iPhone 13, 13 mini, 13 Pro or 13 Pro Max.
You can download the update by opening the Settings app and going to General > Software Update.
