I got an Xperia Z1 Ultra (~6-inch screen). One day the screen just cracked -- no drop, didn't sit on it, just put in my (front) pocket in the morning, took it out a few hours later, and it was cracked. If you search, you can find many others who have had the same experience. Sony refused to fix it, blaming me for some warp of the frame (I've handled this phone gently and never dropped it). Unless I persuade them to change their minds, I'm out over $600.
