Apple on Thursday released iOS 15.1.1 to iPhone 12 and iPhone 13 devices. The bug in question is with regards to calling functionality. Users on the previous version reported dropped calls and other related issues.
To update your devices, go to Settings > General > Software Update and wait for the iOS update to show up. The update weighs substantially at 1.41GB (device dependant). And again, iOS 15.1.1 call bug fix update is out for iPhone 12 and iPhone 13 models only as other models haven’t received one yet.
