HTC One M7 Purple Camera Problem

The camera is one of the main reasons I purchased an HTC One (M7), with its awesome low-light performance, so I was really bummed when my pictures started getting a weird purple tint around the edges. The problem got progressively worse, to the point that the camera was essentially unusable:

So, I did some digging online and, while my case is abnormally serious, the purple picture problem seems to be a common issue for HTC Ones that were manufactured early on in their product run (I preordered mine and got it right at launch). No one is exactly sure what causes the problem, but people suspect it's related to heat, either in the phone itself or specifically at the "ultrapixel" camera sensor. Either way, replacing the camera module supposedly fixes it, and there have been reports of individuals sending their phones in for other warranty issues and getting them back with newer camera modules, whether they reported purple pics or not.

In my case, I went down to the local Sprint affiliate and inquired about a camera replacement. The tech started an insurance report and found that 'camera takes purple pictures' was one of the pre-defined claims, so he was able to order a refurbished phone for me on the spot at no cost (not even an insurance deductible!). A couple days later, I received my new phone and its camera works as well as I remembered. I'll update this post if it starts showing the same issues.

HTC One Back Template for DIY Case Artwork

I got a super-cheap, clear hardshell case (price seems to have gone up since I bought it...) for my HTC One and was interested in making some custom art to put between the case and the phone. I wasn't able to find any templates readily available online, so I spent a little bit of time with a flatbed scanner and whipped one up myself: EDIT: turns out that Google resamples images -_- so just taking this image will not work as-is. You'll need to keep the same resolution (i.e., pixels by pixels) but set it to 200 DPI. Or, just download this one.

Note: I make no guarantees about the applicability of this template to your own case. It worked for me and I hope you find it useful, as well. The biggest potential issue would be with the cutaways for the power and volume buttons, which are pretty large on my case, but it should be easy to remove them if your case doesn't have them.

Here's how it looks when it's all finished:

Sorry about the weird picture. I didn't have another camera on hand, and there weren't any good mirrors at work, so I had to just use the reflection from an old hard drive platter...

EDIT: Here's a slightly better picture:

I made this BMO design along with a couple of other Adventure Time designs, ready to print:
