I'm having the same problem but on Cyanogen 7.2.0
The auto-brightness doesn't seem to be able to respond properly to the light conditions. I've reflashed twice now and the behaviour is persisting. I wonder if there's been some hardware failure.

We just picked up a used Droid for the dev department to play with. The backlight comes on during boot up but goes off as soon as it gets into the OS. Settings appear to be normal (full brightness). Any ideas?
hard reset didn't help. The backlight goes off at the exact moment the buzzer announces the os startup. (if that makes sense)
try using other roms..
Working on rooting and loading a rom right now. I took the phone home with me and discovered the backlight isn't out just very dim. It will change slightly when I move the brightness slider around.
OK, it's now running Steel Droid with the same issue. I have a bright screen in recovery and during boot and a very dim one once booted.
try to un-check the automatic brightness, and set it to full brightness...
if that doesnt work... might be a hardware related problem...
Did that already. Seems like an odd hardware issue. I have full backlight in recovery and during boot.
Here is a video of the issue http://www.youtube.com/watch?v=RxHqN_lycG8
Stupid question: do you have auto-brightness active? If so, maybe your light sensor could be broken.

Auto-brightness is unchecked and the brightness is set to max. There is a very slight change to the brightness when I adjust the slider back and forth.
BTW. It is currently running CM7 with the same issue.
Hello! I have strange problems with backlight
1) back light is turned off -- i can't see anything on the screen with the day light. Changing the brightness in Settings/Display don't help.
2) but, after power off+power on, backlight is OK for 10 seconds, and turns off right after that.
I find the guy with the same problem,but on droid 2 -- youtube.com/watch?v=RxHqN_lycG8
Btw, in "AP Fastboot" mode ("M" key+PowerOn), backlight is don't turn of.
I try some ROMs, they all don't work for me. Only "kexec CM10" ROM have one difference: if I turn the phone off and on, the backlight is turning on for the 1/2 of second, I can see the lock screen, and after that it is turned off...
What can it be? How can I fix it? Any ideas will be very appreciated! I very like my Droid3,and want it back

You'll have to try to turn the brightness up manually. It may be a broken light sensor. If you get in the right light you might be able to see the background and be able to turn it up.

In the dark room, I can see everything on the screen. Unfortunately, brightness in Settings/display does not affect the backlight on my device.
I set the brightness to the maximum, but it still too dark
Is it possible that the problem is in flexible cable?
Hi,
After I installed KitKat with Cyanogenmod 11 on my Samsung S3 Mini the Automatic Brightness function stopped working.
I read all the posts regarding light sensor on this issue (for S3 Mini) and found opinions vary between "no light sensor at all", "light sensor combined with proximity sensor", "light sensor exists but obscured by hardware", "light sensor disabled in kernel"...
My questions:
Did anyone manage to activate the light sensor on CM11? Is there some change I can do in the kernel to activate it?
I also tried to test for the light sensor with *#7353#, but all I get is a message saying "MMI complete" but it didn't work. Does that work only on the custom ROM? Is there a way to do this test on CM11 ROM?
If there is no light sensor then how did the Automatic Brightness function work on the custom ROM? (and I think I remember noticing the brightness changing automatically at different light levels, but I'm not 100% sure).
Many thanks!
SIII mini doesn't have a light sensor so obviously it's not working. That's all.

If that's true, then how come automatic brightness was working with the stock ROM?
Is it possible that the stock ROM was using the camera for it?
(I wrote before: "If there is no light sensor then how did the Automatic Brightness function work on the custom ROM? (and I think I remember noticing the brightness changing automatically at different light levels, but I'm not 100% sure)." I meant STOCK ROM not custom ROM).

Huh? Previously my SIII Mini I8190N doesn't have such automatic brightness selection on stock 4.1.2. Probably you have installed a mod and let the camera determine the lightning conditions?
I can confirm, as far as I know, that there is no ambient light sensor on S3 mini, so the automatic brightness on custom rom doesn't work on our device.
Install Lux app which uses the front camera to estimate incoming light to auto adjust screen brightness.

I'm 100% sure I was able to select automatic brightness on the stock ROM. Maybe it didn't actually do anything, but it was possible to enable it...
Anyway, obviously changing the brightness level manually would be less battery-consuming, but assuming that I'm lazy and will keep it on relatively high settings, would I be saving battery life if I use the front camera for it, or would using it will actually consume more than I'm saving?
Cheers!

Lux can be triggered only when you wake up the phone so it can adjust the brightness. Usually my screen don't go beyond 20-40% when i'm indoor, In my opinion you'll drain your battery way faster with your display set to a fixed high setting.
@solution
You can easily try with Lux Auto Brightness an app witch uses the camera instead of light sensors it changes the brightness every time screen turns on

Most definitely not.
Hi, got an HTC one recently but i'm having problems with autobrightness seems like the low brightness setting for for phone turns screen completely off. I went to brightness setting manually and drag the slider to the lowest point but the screen will completely turn off just before it reaches the last point so i downloaded lux from the store and checked it the screen while turn off below 15 lux. So my question is, is this a hardware defect or can i install firmware or anyother software to calibrate the light sensor? thanks guys.
Hi.
Anybody else have problem with auto-brightness? For me the screen is too dark at night. I'm using stock firmware with all updates installed.
I have the same issue.... I still waiting for some custom ROM.... Maybe some one fix it

I'm having the same isuue on redmi 8. But i think it's due to MIUI 11 or some aggresive adaptation. I have a redmi 6 which have the same issue (although it has no auto-brightness), the screen gets too dim with no reason (as if i scroll the brightness bar to the lowest setting).
I have the same problems of auto brightness which is too dim on dark places, is there any solution even with root ??
Yes , there is actually a solution : Turn Off Automatic Brightness. Why do you guys turn on Automatic Brightness ? I never set it to Automatic.... first of all, Auto Brightness will waste more battery.... I just keep my Brightness to about 25% always... no matter if it's day/night...
