iPhone 4S Camera issues - blue / grainy photos
Have had this issue - intermittent, but more so than not for several weeks. Verizon prescribed a full factory reset and restore. It did not solve the problem. two out of five, sometimes three out of five pictures are blue and/or very grainy. Others - even of the same object, under the same lighting conditions are fine after I stop and start the application.
Add this to the "best ever battery life" and safari crashes from time to time and I'd say my first impressions of the Universe's best phone are rather dim.
Working with Verizon on a replacement.
