Have you tried restarting the phone and/or removing the battery for like a minute and then replacing it? Tech support seems to be working fine for me what about ringing them? 1-877-293-1197

I can give you a pointer. The internal camera cable is probably disconnected. I had to open mine to fix a speaker issue. And had the same problem. Once I figured out what the problem was I was able to re-connect the tiny connecter again and all was fine. In your case you need to have the phone checked.

As much as I'd like to try that out, I'm afraid it would void my warranty, and if it didn't fix the issue I'd be out of luck.

As for restarting/removing the battery, I've done that plenty of times.
