My Lumia 920 stock windows and Nokia camera have been giving me problems over the past few months but it has been getting worse over the past few weeks. Pictures and videos are coming out very grainy and with a yellow hue. Auto white balance is way off and the focus is hit-and-miss at best.

I have done a soft and hard reset numerous times to no avail and have also used the Nokia software recovery tool to no benefit. Right now I am running "windows phone 8.1 update" off the developer preview and Lumia cyan.

Does anyone know a fix for the camera or is it likely are hardware problem that will require a repair. I bought my 920 in March 2013.

From the sound of it, it's a hardware problem. You seem to have thrown every software fix you can thrown at it, haven't you?
But, your problem may be solved by rolling back to Windows Phone 8 Update 3 and Lumia Black. Just a thought.

Get it repaired, out you can try doing it out and manually changing the settings as you go.
