iPhone 12 Pro Max freezes iOS 16

My iPhone 12 Pro Max was fast before the iOS 16 release. I wish I could go back without erasing my iPhone. Family that have iPhone 12 Pro and 13 pro max are also experiencing these issues. My iPhone is slow to respond in facebook, internet, other apps even camera is horribly slow. It either freezes and gets stuck or it eventually responds slowly. I’ve had to turn off my iPhone mane times just to get out of applications. I’ve reset my iPhone and nothing changes. This is very frustrating. I

hope this is fixed ASAP with the next update. It’s only a two year old iPhone.
