    Interestingly on the 4S and "new" iPad, if you have it on in a dark place and walk into a lighted place the bightness will incerease (and shows on the slider); however, walking back to the darken room the brightness will not decrease until the screen goes off.

    I think know how it works;


    Open the brightness setting and then move to a very bright place, you can alter the slider to set the maximum brightness (that means the brightness will never exceed the brightness you just chose). If you're in a dark place, you alter the slider to choose the minimum brightness. It seems you can only set one at a time, eg. not a minimum AND a maximum.

    yes, that's what i'm talking about - auto brightness UP only

  • MichaelAlad Level 1 Level 1

    the problem isn't in adjusting the amount of backlight, the problem is the autobrightness can only increase the brightness, NOT decrease. i have to switch ipad off and on again to reduce the brightness. at ANY brightness slider position.

  • JosephHewitt Level 1 Level 1

    I noticed the brightness go down on my iPhone very slowly, but now it's stopped doing it. I have no idea why that's happened.


    I guess there's just a bug with the autobrightness and there's nothing we can do until Apple updates iOS.

  • MichaelAlad Level 1 Level 1

    it's definitely a software bug since we do know the light sensor is functional. the sad thing it's already the 6th iOS and there still is a bug..

    Yeah ! I have the same problem at first  i thought that its nothin too big !

    But last night i compared my 4S Autobrightness with that of my sister's iPhone 4

    The result was that her iPhone's autobrightness is working absolutely fine !

    I thought her iPhone is broke coz it was lookin like too dim in front if my 4S but after that i noticed that its mine iphone which is not working !

    That's my take on it as well.  What's confusing is that this change only appears to be for the iPhone 4s and up (and iPad 3 according to posters).  Basically what changed is:


    1. Phone now always checked light level and adjusts in real time.  Previously it would only check light level on unlock.

    2. Phone now adjust brightness when screen turns on as opposed to after the phone is unlocked.

    3. Brightness slider actually moves when adjusting brightness.  Before it would it wouldn't.

    4. User appears to be able to set a minimum and maximum brightness. 


    The problem is that none of this is intuitive and Apple never mentioned that they changed this setting.  For what it's worth this appears to "fix" the "problem":


    1. Turn on auto-brightness

    2. With phone locked (i.e. screen off) go to the darkest place you can find.  Unlock the phone and set the brightness to your preferred setting.

    3. Lock the phone and go to the brightest place you can find (hold the phone under a lamp if you have to) and unlock the phone and set the brightness to your preferred setting.


    At this point the phone should set it's brightness somewhere between the minimum value you set and the maximum value you set depending on the ambient light.


    This only works for the iPhone 4S and 5 and iPad 3.  My iPad 2 still works the old way where the slider doesn't move and it only adjusts on screen unlock.  Why is this? I have no idea.

  • Morac Level 1 Level 1

    Note that if the auto-brightness setting is turned off, it appears to clear out the minimum and maximum values and reset them to all the way to the left (no bar) and all the way to the right (full bar) respectively.


    Apple really needs to document their settings better though since none of this is intuitive.

  • MichaelAlad Level 1 Level 1

    no, it definitely doesn'twork on ipad 3. i have it in my hands now and it just doesn't work

  • Mr Backlin Level 1 Level 1

    I have to agree. I have the iPhone 5 and it works fine.  The iPad 3...nah, its not happening.

  • Morac Level 1 Level 1

    Maybe the change is only for the iPhone 4S and 5.  I don't have an iPad 3 so I can't test that.  My iPad 2 works the same way it did in iOS 5.  My iPhone 4S has definately changed.


    Someone else came to the same conclusion as to how it appears to work as I did: works/

  • Brickheadbs Level 1 Level 1

    The problem may be inconsistent. It started working after two days on my ipad 3 and when I told my roommate he showed me auto rightness was not working on his ipad 2.

  • MichaelAlad Level 1 Level 1

    my 4S works fine too. i mean it didn't with ios 5.1 and it does with ios 6

  • MichaelAlad Level 1 Level 1

    looks like the autobrightness bug was corrected for iphones only since we have the new iphone and unfortunately no new ipad. maybe it'll be corrected for the ipad mini and, say, iOS 6.1 ?
