[Q] Auto brightness error... Auto brightness NOT on - T-Mobile Samsung Galaxy S II SGH-T989

I've had a problem with the t989D since I got it. Here's what I want:
**Auto brightness turned OFF and the brightness remain at minimum setting.**
However, with all the roms I've tried (Stock, Juggernaut 4.1- 5.0, Tuesday) I always have the auto brightness OFF and the screen always brightens up to about 75% whenever I turn the screen back on.
Note: the settings still show as if the brightness is set to 0%, but the actual brightness coming from the screen is the same as if I turn the bar up to 75%. When I start to move the adjustment bar a slight amount for the brightness, the actual screen light drops right away. It only stays on 0% as long as I'm using it, but then is really bright again when I lock, then unlock the screen.
Is anyone else noticing this? Beyond that, is it possible to prevent the screen from adjusting it's brightness while the auto brightness nis off?
Thanks for any assistance!!

How does the autobrightness function? IE Normally.

I've noticed with my GNEX that it seems like all of the sudden it won't auto dim. When I unlock the device it will brighten if needed, however if I walk into a dimmer area it will not auto dim. Is this the normal behavior for the light sensor?
I'm used to my Xperia Play which would constantly adjust the screen up and down.
My auto-brightness setting sets the screen brightness lower than the lowest actual brightness setting regardless of whether I'm in light or dark.
There's a fix for it here: http://forum.xda-developers.com/showthread.php?t=1377410&highlight=auto+screen+brightness
I haven't tested that out though.

Yea I was worried maybe the brightness sensor was not working since. Turns out my wife's droid 2 with CM7 acts the same way. Lowest setting until you unlock at which time it only increases the brightness, never decreasing.

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,

dim screen on wake up

most of the time when the phone wakes up and the screen stays dim and grey, as if there is a semitransparent picture in front of the screen. I can see the clock and I can unlock it, but everything is dimmed.
If I turn of the screen one or two times, it usually wakes op again without this grey dim sheet and I can use the phone in full brightness.
I turned off auto brightness, but this did not solve the problem. The brightness slider also turns upp the brightness, but it is still about half as dim as it should be.
can anyone help me in finding out why this is happening?

Auto Display goes to really dim setting sometimes

I leave my phone set for Adaptive Brightness.
First, it's annoying that setting the manual brightness to max and then turning on Adaptive Brightness means that I can't achieve super dim display in dark.
Anyhow, so I leave my phone set to Adaptive Brightness all the time.
And it usually adjusts my display bright or dim(ish) as needed.
Then randomly it'll just go to the absolute dimmest setting and stay there even after a reboot.
I have to toggle Adaptive Brightness off and back on again.
Anyone else seeing this behavior?
I think it's time to give Lux Brightness app another shot.
Hopefully they've worked out the bugs since the last time I used it.

I've not had any issues with mine, do you have a tempered glass screen protector that covers the sensor on the front of the phone? It may be detracting light confusing the sensor.
Nope, no covers. Nekid phone here.

Screen randomly dims

Does anyone know why my screen sometimes becomes less bright? I've turned off auto brightness and put it on max brightness and I can see my screen sometimes becoming very bright and then after a while it becomes darker again. Is there some hidden option I've missed?
