Small gold part left - battery replace
I followed the guide for replacing the battery on the 4s. However, after I had the battery successfully in my hand I noticed a small gold part loose in the bottom of the battery tray. I have looked in all the guides I can find but I do not see it mentioned and I do not see it in photos. I was not rough when taking out the battery and I am pretty sure I did not break anything but I can not see where the piece goes.
Any ideas? The piece is gold on one side, black on the other. There is a hole through it, so I assume that one of the battery contact screws goes through there. There is also a small sprung contact arm coming off the back.
Is dit een goede vraag?
