my friend had this on his 1020 .... it didn't feel right to push and there was a little bit of play that made a creak ..... I got some wd40 spray oil ..... sprayed some onto a tissue ...... pushed the button with the tissue trying to squeeze a tiny little bit into the button and massaging the button as to oil it up a little bit ..... obviously if you go crazy here it could be very bad for your phone ..... if you are careful with how you do it you should be able to oil the button a little bit with a method like this ..... don't use to much , don't spray it direct onto/into the button and genrally do this at your own risk ..... however my friends button is now not squishy , it doesn't creak , it has a smooth operation to it ...... it was quite bad and annoying so much so he was going to take it to a care point or send it to nokia ....... I only tried this method as when I blew the button hard it wouldn't be squishy or click and make a noise , however after a few presses it would soon start to be a little problematic again ....... this is when I thought that maybe I could fix it with the method above and it worked a treat ...... does your button appear to work smooth after you have tried blowing hard on it?
