iPhone 14 Pro 16.2 updated on phone and now phone doesn’t work
My son’s phone doesn’t work since the recent update. You can see his main screen, but it’s dim. Phone vibrates when a call comes in, but unable to answer. Can’t turn off phone. Can’t see any texts or who is calling. This recent update is a known problem. How do I resolve this issue?
iPhone 7 Plus, iOS 12
