My XZ1 device has bended, i put it on to a flat surface (like table) screen facing down and when pressed on the upper right corner phone tosses. I can also spot the curve with my eyes from the fingerprint side of the phone. It's like dented right from xperia writing on the back and humped from the screen. I carried this phone only in my jacket, didn't drop it. I think like they're making this design for years and it must be perfect now it's hilarious.
