How to fix the auto brightness bug in 4.0.4? - Samsung Galaxy Nexus

No matter what I do, the brightness never change. Is there a way to fix this in stock rom?

Auto brightness works for me on 4.0.4 but it's still set too low so I don't use it.

automated brightness control

Hi there, just wanna mention that i did search the forum, but didn't find an answer, just to be clear on that.
So, yesterday i got a desire, switched from a wildfire which i had for 2 months, there is a bit more power and fun to be had with a desire.
But as with the wildfire, i noticed that the auto brightness function isn't doing so well.
If i get up at night and it's all black in my room, the screen is way to bright, i have to use the power control to bring it down, but the downside is that it disables the auto brightness.
Is there anything that let's you tell auto brightness, if it's pitch black, brightness should be this low and so forth?
I've rooted and flashed with leedroid.
I'm running LeeDroid and I don't know if it's recalibrated or what, but it's definitely better than with the stock ROM.
Edit: Just saw I didn't read your post well enough and you've got LeeDroid as well, so my answer is not too helpful... sorry...
The Cyanogen ROMs have settings to adjust brightness.
This was one of the things that annoyed me about the desire.....so much that I decided to fully root this thing and do things my way lol
So I removed the stock ROM, Radio, HBOOT and Recovery and flashed some custom ROMs and now automatic brightness works JUST FINE ^^
Edit: Does leedroid come with automatic brightness settings?...hav u checked under the Display settings? becuase most of the ROMs that support automatic brightness needs to have it enabled and setup to work properly

Well, yes leedroid has automatic brightness, but as i mentioned, it's still too bright at night, i want to tell auto brightness that if i does not detect any light, it should turn the brightness as low as possible and so forth.
Do you turn the brightness down with power control you disable auto brightness and have to manually enable it again.
Even tho there is only one sensor, instead of having a preset value for different amount of light detected, it could be smarter.
Ex. auto brightness is on, it's dark, you go into brightness and turn it further down, phone asks you if you are turning it down because you think it's too bright, you click yes, phone learns that you want lower brightness when it's very dark, you click no, phone does nothing because you had another reason for adjusting brightness.
The next time, phone remembers that you want low brightness when it's dark, so you don't have to do it again.

Auto brightness always low

Using stock 4.0.1 here, and have always had the brightness set to auto. But it never seems to do anything? If I am in a light or dark room it is always dark, often darker than the lowest brightness setting.
I am just worried that the sensor might not be working, if the phone needs to be sent back it needs to be done soon. Anyone else with this issue? I know the sensor that turns off the phone screen when in call works, but the auto brightness might use a different one.

Auto brightness is just simply low on this device. There are some hacks in the dev section to increase it...but they don't work on my ROM.
I just started using juicedefender to adjust the auto birghtness
So auto brightness itself is broken and sensor is pry OK? I wonder if there are any apps to test it.

Simply put a bright light to it and watch the screen brighten up. The sensor is fine.. auto brightness simply is a little too conservative, probably because more people would moan about battery life than screen brightness.
My auto brightness works just fine. Sometimes I have to the screen off then on for it to adjust. Other than that, the levels are fine. I'm on 4.0.3.

Auto Brightness Turning Off

I've had my One X for a week or so now and seem to be having some issues with the Auto Brightness since upgrading to 1.28.
I am still using stock, un-rooted rom and I leave Auto-brightness on most of the time. Sometimes when my battery might be nearing empty I use a widget called 'Dimmer' which just toggles between whatever the current setting is and the lowest possible brightness (it represents that as 10 out of 255). If you use the normal brightness slider, the lowest value (at least according to 'Dimmer' ) is 30.
Now recently when I unlock my phone, the screen has been constantly dim and the brightness is set to 30, which means that Auto Brightness is NOT on and Dimmer is not on. When I check in the settings, the brightness slider is all the way down and I never set this up.
I used dimmer for about a year before now on my old Desire and it was flawless so I doubt its that, and it seems to work on 1.26 fine.
Just wondering if anyone else had been seeing random brightness drops or Auto Brightness disabling sometimes? If so, are you using a 'Dimmer' like widget?
Thanks,

[Q] Adjust brightness

Hi
I just flashed MIUI rom on my wonder.
Then I noticed, I dont get the function to adjust my screen brightness via the status bar anymore.
So, is it possible to get that function in MIUI rom using any mod or whatever?
Thanks !
I've noticed that every time I flash a different custom ROM, *somehow* the auto brightness has been enabled which prevents the status bar brightness swipe from working. Check to see whether auto brightness has been enabled, if it has, none of the settings in the phone will disable it. What you're going to have to do is download an app called Battery Doctor and use it to disable auto brightness. Then you should be able to set up the swipe function in the normal way.....
This method worked for me.....
Don't forget the thanks button if this helped...

Not able to adjust backlight after last update?

Is anyone else having this issue? No matter what I do to adjust my settings, it remains full brightness.
Go to display settings , uncheck auto brightness , now u can adjust the brightness..... If not, reboot the device.
I noticed this myself but i am rooted , using a custom kernel and xposed with some modules so i wasn't really sure what's causing the problem. Didn't have the time yet to figure it out... Is your pixel c still stock?
Still stock. I can adjust brightness with auto brightness unchecked, but the lowest setting is incredibly bright still.
I did a reboot and after that it worked again like it should... , i just checked with mine and it's still working correctly ...
