I followed the Ifixit guide to replace the on/off switch assembly. Stripping to fit the replacement was ok and now I run into a problem. The switch itself on the assembly sits behind the rear camera, but I can’t find the spot where the switch must sit. There is also a “oblong” metal ring attached to the on/off button itself that is also “in the way” I followed the instruction to replace the rear camera in an effort to see if I can find an answer there..to no avail. Anybody have experience that can shed some light.
Have you followed this guide? There are lots of great pictures, especially steps 40-61, to guide you through the process. Maybe you can take some pictures and share them with us for more help.
