I was told that the camera issue (purple tint in low light) is caused by a heat shield that gradually degraded which explains why the problem didn't show up until after several months of use. You can return your phone to htc where they will replace the entire camera module along with a heat shield that (they say) will not degrade with time. I'm waiting for my phone to be returned from the houston repair facility now. HTC really should have gotten out ahead of this problem instead of letting it fester. A recall would have been crazy expensive but so will the ill feelings and bad rep generated by their lack of communication about this defect.
Consider the massive amount of ONE owners who are living with their defective cameras because they were given the runaround by their carrier and just gave up. HTC should have contacted all affected owners about how to have their phones repaired. I received false information from AT&T which was to wait for the update. Basically wasting away the opportunity to take halloween and new years photos.
HTC did not offer a mailer to me, I paid a total of $14.15 to mail my phone Priority Mail (with two day delivery) and now, 10 days later, my phone is still "in repair" The facility is in the same city as I am and the delivery arrived on Tuesday the 21st. They didn't even scan my phone into the system until Friday the 24th. I had been told the entire process (shipping and repair) would take 8-10 days. There is an apparent disconnect between the HTC reps online and the repair facility. I'm sure this isn't the case for all other users but if I had known it would be closer to 2 weeks repair time I would have gotten a backup phone to use.
I love my One and loved my previous Inspire, but this experience has certainly put a dent in my opinion of HTC's customer service.
