There is something like a silicone holding the spring so tight that I was unable to turn the lens. At first I put a piece of paper on the lens a held it down with a pen and heated the the silicone with a heat gun a very little and carefully. Then I poked it and removed it. As the spring got loose a little the lens started to move. I don't why they do this or it just depends on the person in the factory at the assembly line.
