IPhone 4 Home Button Not Working? - 2

I'm not sure why my old Apple iPhone 4's home button is not working but I'm really desperate to have it fixed. Does anyone know any quick fix for the home button?

You will need to take it apart and try cleaning it all out, if this doesn't work you will have to either order yourself a new one to try replace yourself (Follow some utube videos) but you could damage you're phone and have to pay even more for repairs, or the less risky way is to get it repaired by a professional where it will be done right.

Also taking the phone apart may void you're warranty so I would take that into consideration, some companies can repair it and it will not void the warranty on it.
