Not sure if this has been posted here before, but if so, I think it's worth mentioning again. Yesterday I went to use my iPad Pro 12.9, and immediately noticed a huge crack in the screen, from the top left corner, to the bottom right corner. I'm the only one that uses it, it's never been dropped, and it's been in a case since the day I bought it (about 9 months ago). It had to be a defect with the screen. I took it to the Apple Store today, and they replaced it for free. I don't have AppleCare, but it was covered under the one year limited warranty. So if you have a cracked screen, don't assume you're SOL. It's covered under the limited warranty if there is just a single crack, and there is no "point of impact". Mine was in perfect condition, other than the giant crack.
