You should go back to where you purchased it from and request for an exchange. That shouldn't happen and if you recently purchased, there should be no reason not to exchange the faulty device, assuming it really is faulty.
Ladybug4him, It's truly disheartening to learn that your new iPhone X is giving such difficulty. jav6 and Sean.K.Ching asked some really good questions and provided good advice. Since the phone is recently purchased and is running hot; it would be best to take the phone back in for an evaluation of these issues. We never want you to handle a phone that is getting hot this way and your safety is our top priority.
