Auto brightness not working on iPhone 5?

I'm having the same issue....

Same issue here with my iPhone 5. Older iPhone 4 with iOS 6 update works just fine.

Confirmed to have the same issue as well. ********.

This seems to work for now. http://forums.imore.com/iphone-5-forum/240720-auto-brightness-bug.html#post19240 91

I'm having the same issue.

I have a same problem with iPhone 4S my iPhone 4 is alright yet ?

I have a same problem in my I phone 4s when Update to IOS 6

Yup same issue here. It's a little annoying and I see NO change what so ever from low light to bright situations. Sub. to this post for an answer.

EDIT: Did some messing around with it and it seems that it is just REALLY slow to respond at all. It will however move slightly when placed in extreme differences. So hopefully Apple comes out with 6.1 real fast for a few things like the Wifi/Maps/Lighting issues. Cheers

There is nothing wrong with the auto brightness.

When you have auto brightness enabled the slider works as the minimum brightness setting with auto brightness.

If you have the slider too high the brightness cant reduce because youre not letting it.

Set your brightness at about 25% and you'll see what I mean.

Umhm ***? Isn't the point of auto brightness is for the phone to automatically dim the screen if it's too bright out?

having the same issue here. is there a software fix from apple. can anyone from apple respond.

The link above seems to work but its kind of dumb as its worse than how it used to work on my iphone 4. there are a couple of time it does not work like the lock screen etc in iphone 4 but it does work very well at other times.

I'm having the same problem. It did for the first night I had the phone but I never got into daylight until Saturday and now it's not adjusting. It looks like a software problem as 4S customers are saying the same thing too.

After some further research it appears that in iOS 6, auto brightness can remember preffered brightness setting dependnt on ambient light settings.

For example with auto brightness on, if you are in side with moderate light and you feel the screen is too dark you can increase the slider to an amount you are happy with and it will remember that brightness for that ambient light setting. Then you can go out side and set another pre-determined brightness for lotsof light and the phone will remember.

SO, if you were in a dark room and then turned auto brightness on and maxed out the slider it will remember that in dark setting s you like brightness full hence no auto brightness.

Ok so I've done a bit on this too as more testing the better. I set my brightness low for dark conditions ie at night in bed. Switching the light on and holding it up it'll gradually get brighter up to its brightest.

Then when turning the light off its gradually got darker. This was in the situation where I didn't lock the phone.

I then applied light to the sensor and the phone lit back up again. I then locked the phone and turned out all the lights. When I entered my pass code it stayed at the lower brightness. So it just seems that you the previous post is true in that iOS 6 remembers what light you like for the current situation.
