Please remove ios 16 from me quickly

This is a user-to-user technical support site operated by Apple. We are volunteers here and bound by the same rules that you agreed to when we joined here. Apple does not support users rolling back the iOS version and provides no user accessible means to do so. There are millions and millions of people using iOS 16.0.2 and not having the issues you are having so the problem is probably your phone and not the update. But you can always click on the Get Support link at the top right of this page and have an Apple Support person tell you that you can't roll back but perhaps they can help you with your issues. Or you can use your favorite search engine. Your choice.
