@JimKnuckles (or anyone whose phone is not exhibiting the green tint issue), can you do a quick test for me with your replacement phone? Can you take some comparison shots using the front facing camera versus the rear facing camera? I took a couple of test shots the other night to compare the colors produced by the front facing camera to the colors produced by the rear facing. I discovered that the colors from the front facing camera were dead on, and were strikingly different than those from the rear facing camera (which exhibit the green tint). It would be interesting to see if the rear facing camera on your new phone exhibits colors more similar to the front facing.
For reference, here's a sample of front versus rear (note that while the photo from the rear camera is much crisper, it is also dark and exhibits unnatural green in some areas, most noticeably in the house in the background which should be a light brown). The colors in the front facing pic are pretty much accurate to the real-life colors.
