My camera was working just fine, but then I noticed an increase in the purple tint a month ago. Around that time, I called HTC, and they suggested that I send it in, or alternatively, have my carrier do it for me. I then sat on my hands until about 10 days ago, when I called my carrier to confirm how much time I had left on my warranty; turns out it was only a few days. So I talked with them about options. If I sent in for repairs, and they couldn't repair, then by the time we figured that out, I'd be out of warranty, and no longer eligble for a swap. As much as I dislike the idea of a refurb, the CS rep talked me into it, stating that refurbs were basically pristine, and was either an essentially new unit, or one which had been completely gutted by the manufacturer (again, making it pretty much new). So I started that process.
Today, I got a voicemail telling me that the HTC Ones are on back-order, but if I want, I can take a Sony Experia ZL instead, or wait for the One. That was followed by an email, again saying no current ETA, and would I take an M8 instead. Tough choice...
