HTC: "Don't carry your phone in your jeans"

Like many 8X owners, the soft coating on the bottom and corners of my 8S is turning black - I thought I was seeing things, but it's actually as bad as I thought. I compared the device to a unit in store and that is blue and mine is more grey/black at the sides now.

So, what was HTC's response to a phone that's turning from blue to black within a month - and seemingly going to get worse?

"Exposing the phone to abrasive surfaces could color run the material of the unit (e.g. carry phones in pocket on jeans"

Well, there we have it, if you own a HTC 8S/8X don't put it in your jeans pocket.
