In this case, never disassemble the camera yourself. The internal parts of the camera are very complicated. If you are not a professional repairman, it will be easy to disassemble the camera and fail to install it. It is recommended that you use a special air blower and a small software for the camera. Try using a brush and if you still can't get it out, you have to go to a repair station to disassemble and repair it. There is no other way. You need to be more careful in the future
