Bought an IPhone 12 Pro Max. Ran into the same problems as some of the people in the forums. Got an IPhone 11 and the symptoms went away. Only problem is that the battery life sucks and the camera is not as great as the iPhone 12 series. May just bite the bullet and get a 12 or 12 pro and hope the problems I had with the screen for iPhone 12 Pro Max are not as prevalent
