    So far I don't have any yellow issues or signal issues but my screen seems pretty dark in a low light situation when the auto-brightness is set "on".

    I have the same setting as I had with my 3G but the iPhone 4 seems much darker in low light.

    When I put it under ample amount of light, the screen is bright and if I turn off "auto-brightness" the screen is pretty bright as well.

    When auto-brightness is on, is it normal that the screen is dark in a low light situation?

    Yes, this is normal, and it's good that the iphone 4 gets darker than the 3gs

    I noticed this while I was playing with my iP4 last night.

    To the best of my recollection the 3G and 3GS were also very sensitive to light fluctuations when first released. Enough compliants generated OS patches soon thereafter that 'fixed' the sensitivity of the ambient light sensor when set to 'auto'

    To be honest I tend to turn auto brightness off after I've owned any iPhone after a few weeks. I just prefer the constant image brightness. I ususally keep it at half brightness or less so battery life has not been an issue (at least not combined with auto lock set to 2 minutes or less)

    was just about to ask this same question. is it correct that when auto brightness is on in darker rooms the screen is much more dim as opposed to a room with more light the screen is brighter? I assume its similar to the iPad as when I use it in a dark room the screen is dim. Is this how it should be or is my auto brightness broken?

    Glad to know that it's normal...I guess I was quite used to the 3G's auto-brightness level. Thank you everybody for answering my question~

    The auto brightness should adjust to the same brightness as the ambience. If in a dark room the iPhone should be dim to the level u set the minimal brightness slider to. If outdoor, it should auto adjust to brighter to match the outdoor brightness. Hope tis helps
