Hello everyone, I was finally able to solve this myself.
My game is (VR + Andorid) + (Multiplayer).
The problem was that for (Transform body) variables were passed that were set by (Server), as soon as I set this task for (Local client), then all the shaking went away.
I believe this is because the FPS of (Server - PC) is much higher and faster than that of (Client - VR+Android), although if I display (Stat FPS), then both (FPS = 60).
Anyway, hope this helps someone.
