Yep I've got a 2 month old grey carbon HTC 10 and Spigen case that doesn't cover the whole of the front and the paint is coming off. Also the screen has developed a single crack running about the 1/3 of the screen. I haven't dropped or bashed the phone so I'm not exactly thrilled at the moment.
I have the Carbon Grey and had it since April,
I pre ordered the Spigen slim-armour case and screen protector for when I had the phone, Had the case on since I've had the phone and have no marks on the phone no scratches no rub marks looks like new
