I operate an Apple/Mac repair/service/support business in...
Had an issue when putting the screen back on, the side where the cables attach would not sit flush. At first I thought the cables were pushing the screen up. Turned out to be the battery cable shield was just a fraction too far down toward home button. After loosening screws, nudging it up slightly and screwing back in, the screen sat flush as it should. In case anyone else has same issue.
