iOS 16 has a feature that will allow iPhone users to deploy security patches without a full iOS update, and they can also choose to roll back the security updates.
The Rapid Security Response system in iOS 16 can install security patches without fully updating your iPhone, or even without having to restart it, in some cases.
By default, Rapid Security Responses are installed automatically, but Apple has implemented a way to remove them, reports MacRumors.
