Received my iPhone X from Apple preorder today and was just finishing setting it up -- I was even able to make a phone call -- when the screen suddenly became completely unresponsive to touch. I have been on with Apple Support via chat and have restored to factory default via iTunes -- no help. And their best response is to walk into a store and see if they can exchange it, or make an appointment for repair. They can't even tell me what local stores might have stock for exchange. They just give me the phone number for my local store, which says they have too many calls and automatically hangs up on me. This is how Apple deals with a defective $1150 phone? Pretty pathetic.
