I was replacing my brother’s iPhone 5 battery and after opening the screen panel a small metal part with two holes fell out and I have no idea where it goes. Also, this black strip towards the home button appears loose and I’m not sure where that goes, either. Photos below: https://goo.gl/photos/cRzqfSffKxCntwVE9
the small metal part on the left hold the home button flex in place once you connect it. is there a screw on the home button flex to the right when you’re looking at the back of the lcd? if you lost if you could just use a bit of double sided tape I guess where the screw ought to be. Update (01/26/2017) you’re welcome, you could even forget about the metal part, it won’t matter anything if you do, it’s a headache to put back. I do it for customers of course but if it was mine….depends on my mood if i were to put it back. it needs to first get set into the top area, there are two notches in it then forced down towards the bottom. you’re welcome!
