So I was doing a housing swap on an Iphone 7 plus and when I got to the point where I put the buttons in the new housing I noticed the tiny circle in the middle of the Retaining Clips is gone so now I have no click when I press down on the button. Is it possible to use one from a older model and if not where can I find them new? Recommendations would be greatly appreciated:)
i assume you mean the shiny metal disc that recesses into the centre of the buttons, you probably could take them from an older model or the old buttons you replaced
