Why is my iPhone X randomly shutting off?

I recently noticed that my iphone X (64gb) has been randomly shutting off. It started happening first with watching videos such as YouTube but became much more consistant as time went on to now just shutting off even after just rebooting it.

I did notice the issue begun about 2 days after dropping the phone, however the phone has NO water damage at all. With that being said I visit the apple store with no help except a “hard factory reset” which we did and did not fix the issue.

In analytics the page is full after one and another “bug type 211” and throughout the coding, the one repeated line is “Gesturetype UIGestureStudyInteractionEventTypeLongPress” Has Attention; null: Movement “Orientation”

Orientation seems to be the common repeated word throughout analytic log.

I recently also noticed that the phone sometimes will begin to overheat to the touch with minimal usage no usage at all.

The issues have gotten so persistent that I had to switch to my i7 in the meantime. any advice would be much appreciated. thank you
