Just took off my case and cleaned phone and realized the volume buttons have changed. now when i push them they go in quite a bit without any resistance and finally hit the resistance part and then click. almost like there is lots of "slack" for a lack of a better word",in there. in the past it would give resistance right when i pressed it. could it be my case? my case makes it hard for the volume buttons to be pressed. i have a belkin candy sheer and its great but the volume buttons arent the smoothist. getting a little worried I am messing up the buttons. anyone have issues with the buttons weakening? Thanks.
