Aporte original por: nick ,
I have the same problem however only the volume down button will not work. HOWEVER, it will work if you apply some bending pressure to the entire phone (read it on another forum) while using the down button. This tells me that the flex isn't damaged, otherwise it wouldn't work at all. There have been many others with this exact issue. Mine is a little different than the OP but thought I would note this. Has anyone found a fix for this issue?
