I think I found a bug in the 3GS.

    So... the screen dimmed after a certain amount of time, and when I went to use the phone again, it didn't "re-brighten"...

    I had to go into the settings and adjust the brightness slider, at which point it lit up again fine.

    I don't know if this is 3.0 in general, or if this is 3GS specific.
    I tried searching here for this, but I couldn't find any similar threads.

    I noticed that yesterday with my 3G on 3.0, so maybe it's a 3.0 issue.

    Ahh ok.
    I figured it had to be 3.0 in general, I should have worded my topic title correctly..

    Happens a lot to me, especially when I'm playing a game just after waking it up from sleep.
    It eventually corrects itself and every time I'm like "ooohh, now i can SEE things"

    I think the light sensor isnt all that smart in some situations.

    This is happening to me too.

    Is the auto brightess setting OFF?

    I have mine off, and just now when I go to pick it up after a few minutes, the brightness is down, but I have to do into settings to tap on the brightness sliders to get ANY brightness to come back.

    this is wrong,

    My 3G does that, and sometimes it brightens much more then it was previously even if the lighting level had not changed.

    I saw it using 2.X on my 3G as well. All I had to do before was lock the screen and then unlock it and it seemed to always fix it.

    I think you can disable it by turning Auto-Brightness off. Not sure though.

    I can get sound for incoming calls but on the ipod, when playing a track or video there is no sound and the sound bar has gone!
    In settings under ipod there doesn't seem to be anything wrong - so what has been disabled - any help appreciated.

    I noticed it did that too, but only when I had something covering the sensor. Make sure that's not the case.

    You might have the ringer volume up and the regular speaker volume down. Try using the volume buttons in the iPod app.
