I recently purchased a refurbished D5100 and noticed that in AUTO mode, many, if not all of the pictures I take, are very grainy, then I noticed that the camera sets the ASA to 3200. Almost every flash picture I take the camera sets ASA to 3200. In P, S or A modes, the ASA numbers are set to a reasonable number, 200 or 400 or whatever ASA maximum number I set it for.

Is this the way the AUTO mode is supposed to work for the 5100, or do I have a defective camera? I have been searching on the web to see if other 5100 users have the same problem, but never found anyone having this problem.

I've used many Nikon digital cameras since 1999 from a coolpix 950, 4500, 8800 & D60 and non of those had a similar problem in AUTO mode.
