Most notably iOS 12.1.4 addresses the notorious Group FaceTime bug, which made several headlines last week. Group FaceTime was taken offline when it was reported that users could use it to eavesdrop on others. The latest version of the mobile operating system reenables the feature.
Unfortunately, the update introduces some new problems for some users. At least one user has complained that after installing, his phone will no longer “accept any SIM.” Another owner lost connectivity with his SIM card as well and calls iOS 12.1.4 an “utter failure.” Still, others have found that their phone will not connect to WiFi after that update.
