While I was working on the camera, the camera bounced in and out, making it very difficult to work. In addition, the camera also disappears when our work can not access the camera because it disappears from the application. Please help solve this problem. Because it is very difficult to work, let the new camera stick with the old camera first. Because when we turn on the automatic function, it jumps to the bottom, it is very difficult to work. What is important is the new camera function, when we run it jumps out of the program and can not be opened. Please help solve this problem, thank you
