iPhone 7+ with a problem nobody can explain

Hey so I have a bit of a story for context, One day I was riding a motorcycle and my phone fell out of those phone holder things and the camera got ran over by said motorcycle and I picked it up with pretty much no physical damage and I didn’t realize until a few days later when I used my camera and pointed it away from me and when o did the camera was blurry and I kid you not THE PHONE STARTED JERKING moving around left and right until I closed the camera and does that every time I open it I contacted apple support but the lady thought I meant the camera view was shaking but no the WHOLE PHONE SHOOK eventually I got a new phone and just found where it was and wondered why that happens but nobody seems to one help me out here I want answers,
