When i assembled my new homebutton, I couldn’t mange to make it work properly. The screws, as described earlier, had to be adjusted but even this wasn’t enough. Once I put the iPhone case together and tightened up the screws it would push the metal cover all the way so the button wouldn’t click. After trying multiple screw settings I came to a somewhat unorthodox solution. I placed a piece of folded paper under the left corner of the metal cover. Now it wouldn`t press the button anymore and the paper keeps everything in place until fully reassembled.
