I use auto brightness and i notice when i turn my screen on there is a lag between when it reads the ambient light and adjusts the screen. Can this lag be adjusted or can the parameters be adjusted? I thought i read somewhere that they can but i cannot find it.

I figured this would come along by now but for some reason it hasn't. On my iPhone I could set my brightness that the auto brightness would adjust accordingly. Because the auto brightness is generally too bright or too dark. Also maybe adding some timing controls for how long before the auto brightness adjusts. The displays in these devices suck down the battery like crazy this would help significantly.

I too thought we might have seen this by now. I know there have been some tweaks in ROMs, but a slider that sets the sensitivity or the upper/lower limits would be excellent.
u talking about this? http://forum.xda-developers.com/showthread.php?t=708660
extended controls has a auto brightness controller sort of if thats what your looking for

Extended controls has an Auto Brightness setting, same as Froyo Power Control widget.
What OP wants is auto setting where you can control sensitivity of light sensor.
Ok I'll try explaining again. Communication isn't my strong suite. Basically, on an iPhone you can set auto brightness, then under auto brightness checkbox you have a slider that calibrates the brightness throughout the range of the ambient light sensor. So it's still a brightness control it just works in conjunction with the auto brightness setting. Being able to fine tune the brightness throughout the range of the ambient light sensor would be a bonus because with the current auto brightness I can barely see the screen in daylight but it's not maxed out because I can still adjust it all the way up with the power control widget and the opposite is true at night, i could go dimmer at night and still see the screen clearly. Strictly copying the functionality of the iPhone wouldn't fully address this. An app would be ok I suppose but I'd much rather see a system mod. I really hate apps like Trackball alert, nothing against the author I just don't like running an additional app to address the lack of a feature in the OS itself.
Good thought
I agree completely. I'm a recovering iPhone user and the adjustable auto-brightness is a feature that I desperately miss. One of my top complaints about android.
This idea is fantastic. It's something I've been thinking about too (never knew iPhone has it though)
When indoors I sometimes find auto brightness too bright. When outdoors and its sunny sometimes its upper limit is not bright enough. In both situations I have to turn off auto.
Actually last night I noticed that auto brightness was dimmer than the lowest brightness setting. I reckon that a lower/dimmer threshold should be available too on the manual brightness settings.
Hi, I have an I9100G, with rooted stock ROM, firmware DZKI1, Android 2.3.5. I'm just curious about a couple of items in the Display settings. There's an option called Brightness - Adjust the brightness of the screen, and when we click it, we can adjust the brightness or select the checkbox for Automatic brightness. On the same screen, a bit further down, there's another setting for Auto adjust screen power - Save power by analyzing image and adjusting LCD brightness. Anybody knows what's the difference between the two?
One uses an external light sensor to adjust for lighting conditions.
the other uses an internal sensor to adjust the colour display depending on the background of the graphic and how many colours are used.
Is there a way to change where the light sensor readings trigger a change in brightness level?
Currently the phone change from lowest brightness to higher when reads 30lux and change to lowest brightness when reads 10lux.
It's annoying for the phone to change to lowest brightness when i still in a light up room but just pointed away from light sources. And also it's also not switching to higher brightness when i need it in a dim environment.
So, anyone know of some app that can adjust these values? Or point me some direction to work on it.
Light Sensor is Ok, but...
Using z-device test I compared the light sensor readings between SGS2 and the NS. The light sensor seems to be correct. Still, at 10 lux, the SGS2 is setting the brightness value to its lowest and the NS, not.
I'm starting to believe that there is a a problem between the mapping from the light sensor and the brightness level. If I'm not mistaken this can only be fixed/adapted within the ROM.

As from what i read, S2 seems to divide the screen brightness into 5 level
http://forum.xda-developers.com/showthread.php?t=1235212&highlight=auto+brightness
However, the mapping of these five level to it's correspondence light sensors reading seems to be odd.
let's just call lowest brightness as lv1 and highest as lv5,
The phone will stay on lv1 whenever the sensors read from 0-30lux
The phone will drop to lv1 whenever the sensors read 10lux.
The gaps is just too wide to give a pleasant viewing experiences, often stay on lv1 brightness while i'm no longer in pitch black area.
if there is a way to change this, i would prefer to set it as
stay on lv1 whenever sensors read 0-5lux
drop to lv1 whenever sensors read 2lux (the lowest brightness lv is only feasible for me when inside a pitch black environment)
Since there is a file determine it's brightness value for each lv, so i'm thinking there should also one for it's mapping.
Anyone noticed that under certain lighting conditions on max brightness no auto the s6 edge brightness randomnly increases?

My auto brightness turns itself off.. dunno if my finger touches the box.. but gets annoying for sure.. buggy for sure
if you have the Samsung auto app installed.. remove it..it has a bug that deactivate the auto brightness
its a well known bug ,i hope it will be fixed,mine is off but the phone acts like its on
If you have adaptive color selected, it will do that. The only reason I keep adaptive color on is it allows the brightness to go over the "max" brightness the slider allows.
It works, it's just that it over compensates in the dark.
I know there is probably not much that can be done about it, just thought I'd ask.
I think the Auto brightness is adjustable.
I agree it gets too dim, but works fine in normal lighting conditions.
The brightness is adjustable, manually. I have not found any means of adjusting the bounds of the auto brightness mode. It is the low intensity limit that needs adjustment.
I would like to be able to have a feature like adaptive brightness like what's on pure Android without a third party app...

While on auto brightness tap the sun burst directly opposite the checked auto brightness. Voila!
0-50-90
But then the whole phone goes dim. We want the brightness of the 2nd screen to stay bright at all times so we can see it.

Awesome! Didnt know about that feature!
I find the auto brightness is a little too dim. I would prefer if it was 10-15 points brighter than what the algorithm chooses. Now I leave auto brightness off in most cases of active use
