Why is my camera "Fujifilm X30" opening up the playback interface when I shake the camera. Normally, the playback interface is supposed to open when pressing the button that has a right arrow inside a square, but when I shake the camera the playback interface opens when it is not supposed to. If I record a video and shake the camera, the camera will stop recording the video and open up the playback interface. How am I going to fix this problem?
