Apple's latest update fixed a major bug, but also made matters worse for many iPhone users

Late last week, Apple rolled out iOS 12.1.4. The update removed two vulnerabilities, one involving a "memory corruption issue" and the other allowed "an application to execute arbitrary code with kernel privileges." But more famously, the update also removed the Group FaceTime bug and re-enabled the feature on affected iPhone units. So, this is obviously a build of Apple's mobile operating system that you would want to install on your iPhone, right?
There are a large number of complaints on social media, with some complaining that iOS 12.1.4 has not only broken their cellular and Wi-Fi connections, but has also negatively impacted the performance of AirPods, Touch ID and other features. These problems have been going on since iOS 12.1.1 for many, and quite a few iPhone owners are echoing the sentiments of one Twitter member with the handle of @navansh_deorah. He tweets, "What is wrong @Apple? Please solve this stupid bug. This has been ever since iOS 12.1 . We are losing it. Come on man, we know you can fix this. Using iPhone X. @AppleSupport."
And considering the bug fixes on iOS 12.1.4, this update cannot be ignored. Hopefully, iOS 12.1.5 goes better.
