There's a ghost living in my iPhone X

Hi, guys so woke up today and were using my 1 week old iPhone X and suddenly it started acting out on its own without me touching anything at all. Scrolling Sideways, clicking on apps, typing letters randomly. After a while, it got better but it reoccurred shortly after. Anyone experience the same thing or has any slightest idea what is wrong with my phone?

- Got in touch with apple support chat and they tried to troubleshoot the problem but nothing happened.
