I thirdly will ask for what the copper sticker is for!? I thought some kind of grounding?? I tore mine and the front facing camera is fuzzy now. It looks grainy. Almost like it isn't grounded good. ANY advice here would be appreciated.
Now is a good time to remove the gold grounding finger. I used the condiments cups from Wendy's (fast food restaurant) to hold my screws for each step. Hope this helps.
I found it quite easy to remove the camera at this step. Just simply move the camera up and slip it to the left in order for the arm/tab to come out.
