Hi all, first post here. I sent my iphone 6s to apple to swap out the battery under the recall, but apple says they can't fix it because I have a broken LCD. The problem is that the phone has an intact screen, there is no visible damage on the screen. Is it possible to have a damaged or cracked LCD that is not visible to the naked eye? I am trying to decide if I should pay for this fix or if they made a mistake. This is the picture they sent me..
