Phone fell down and slider won't work.

Phone fell down and slider won't work.

So I "Accidentally" threw my phone to the ground in a rage flash, but when I picked it up, it worked fine and nothing was broken besides the body, which is not a big deal. What bothers me is that the phone lost its springy resistance when it slides up and down. I searched throughout the web for answers to this issue, but there is nothing so far. Will someone help me please?
