    I just got an iPhone 3G and when the screen dims just before sleeping, it is so dark that I can barely see the icons. This is much darker than the dimming I have experienced on other iPhone 3G's. Has anyone experienced this problem? If so, is it a hardware problem that I should be worried about or is it a simple software fix?

    I do not think auto-brightness is the right setting for this. I did change auto-lock to 2 minutes, but the problem persists.

    Not to be snarky, but why does it matter? If it is doing this then you haven't been messing with it for a little while anyways.

    I doubt there is an bug or problem with your phone.

    Right before the iPhone sleeps and locks, it turns off the backlighting and then the entire screen is turned off.

    This 'dimming' you see is the backlighting turning off.

    Not much you can do about it.

    Re: Apple iPhone 3G LCD Display Inconsistencies...

    I know it's been 81 days since this thread was first posted, but doobs has a valid point. After searching through quite a few pages on both Apple's website as well as the WWW in general, there is very little on this topic.

    It's true! There is definitely something going on here with the iPhone 3G displays. Either there is more than one model being used in the assembly of these devices or there is a quality control issue at Apple. I just got my iPhone 3G 16GB model replaced with a new iPhone from Apple and there is a BIG difference in the displays of both iPhones. After powering up my new, replacement iPhone, the very first thing I had noticed was the reduced intensity of the display. Whereas in the first unit, I had always used a Settings->Brightness intensity of approximately 1/4 or 25%. The new iPhone was set on 1/2 or 50% Brightness and it was not as bright as my first iPhone 3G. How do I know there's a difference in the two iPhone displays? When the Brightness is set to the minimum intensity for both iPhone 3G's, the new iPhone 3G display is completely dark - like it's in sleep mode. Even in a dark room you can't see the display for the ten or so seconds right before the display powers down. I prefer the first iPhone 3G display because the LED backlighting was so much more vivid!
