Get a replacement through apple. Don’t mess around. This is too pricey an investment to be a troubleshooter for them.My screen is still unresponsive until I pick the phone up (12 Pro Max) and then it still doesn’t work with my thumbs. The update did fix an issue I had with my photos after the set up was complete; the photo count was correct and the memory was reporting space taken by photos but none of my photos were there, just a tiny picture of a cloud where each one should have been.
I’m not that impressed with my new phone to be honest, I expected better
