See attached pic and notice the module just above the HTC logo that houses the flash, lens, and what appears to be the speaker.
The plastic film that covers the lends has become very scuffed up over the past year and a half which results in very hazy and/or blurry photos. I want to see about replacing that part, but I don't know what that module is called. I've searched for
htc trophy lens cover and
htc trophy back cover and nothing relevant appears to come up.
