How do I stop my camera zoom from malfunctioning

ThunderArt Comics just came across this question and I am certain that by now, you either have the camera fixed or are no longer using it. So, consider this an informational answer only.

Since your camera dropped, it is most likely that you knocked the lens of it's taacks or bendsome of the lens tubes. If you look at the lens head-on you can possibly to which side it may be leaning. You can try to gently push or pull the lens, while turning your camera on, into the proper direction. See if that will reseat the lens. Since individual parts are not available for this lens to complete a repair, you will most likely having to change the complete lens. There now is a YouTube video available that would have been a great guide for you at the time this happened. Of course, there are now also guides Samsung WB35F that would have helped you to at least get into the camera :-)
