PHS

I am having the same issue and had the camera sent to the repair service under guanrantee. They pretend now that I did cause the damage. During my holiday, I just put some scotch to keep the button horizontal and working no other way to still use the camera. Seeing some tiny trace of adhesive the repair service said I have to pay for this repair (no guarantee): 130€ What can I do to get this properly handeld under the guarantee as this seems to be a well known defect of this model?
