How can i disassemble the device safely and eventually fix/change the vibration component? My kid who was playing with it stumbled and the device fell on the ground. The left trigger fell off but it was like super easy to put it back, but since then the vibration hasn't worked and when i move the device i can definetly hear some pieces moving inside. Other than that the device works wonderfully tho, no overheating, no crashes, nothing else.
