Hi,
I have a problem with my SGS. When I turn the option "Auto brightness" on, the phone wont change it's brightness automatically and depending of the ambient light conditions..It just stays at it's lowest setting.
I made a test of my proximity sensor and it's working fine, but won't react on auto brightness..
My ROM is JM8 with raspdeep OC/UV kernel with Voodoo b4 support..
If you have Voodoo color installed auto brightness wont work afaik.
No , it's Voodoo without color fix included.
Anyway I just figured it out that it happens only when battery is under 5%. When plugged on charger everything seems to work as should.

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.
Auto brightness seems to behave very unpredictably--when I wake my phone and unlock/use it, it will remain at dimmest setting (too dim), and will seemingly randomly move to a more appropriate brightness (not with intense activity, it's really random), and will again randomly revert to dim setting (not with stoppage of activity).
Is auto brightness messed up with android or the note, and how can I fix it? Just set a manual brightness level?
Running cassie x lite rom and latest franco kernel btw.
No advice about this anyone?
Automatic brightness issue
Hello Friends, I have a similar problem as the OP, octavian90.
For my Galaxy Note, following the sequence below,
Applications > Settings > Display > Brightness
By default the slider for Automatic brightness is towards the middle/centre.
I have unchecked Automatic brightness and calibrated the slider to the extreme left.
I have come across the following strange observations -
1] When I unplug my device after charging, the slider resets to the default level.
2] After I recalibrate it to the extreme left once again and make a phone (voice) call, the slider resets to the default level over again.
Is this normal behaviour or does my device actually have a problem? I am very confused and worried. The device is not even a month old.
Eagerly awaiting your expertise. Thank you octavian90 for initiating this topic.
Friends, awaiting your much needed replies to my queries above.
Have you disabled the screen saver or what its called that adjust the brightness automaticly.? Works like a auto brightness but it can adjust some things brighter and some dimmer eaven on same light....
I just checked my settings and the have the slider all the way to the right because last time I manually adjusted brightness for reading in full daylight. It is currently on automatic brightness (I prefer that setting and don't find it changes too often or too laggy)
I just then manually adjusted slider to about 20% from left while on USB charge then turned automatic back on again. I then removed charger and it still shows automatic and slider about 20% from left.
Could be a ROM/Kernel issue? I am using Rocket ROM with Franco Kernel.
I don't think the position of the slider matters when backlight is set to auto. Or does it?

No it doesn't matter when on autobrightness. But it should remember the last manual setting chosen so not sure what is causing that glitch.
Hm never really paid attention to the behaviour of the slider. I will take a look and report back how mine works.

What I found out: On my device the position of the slider before activating auto mode is completely irrelevant because as soon as I activate the auto mode the slider is reset to its middle position.

Interesting - just turned autobrightness of and you are right - slider went to the middle. Must be by design then. Problem solved

Sorry SoonHD2, I did not understand what you meant. I am confused with the screensaver part you stated.
A humble request for an explanation, if required. Thank you.

This happens with my Galaxy Note as well. Thus, it seems like it is meant to be this way.
I will keep an eye on this and report if and when the Auto brightness slider acts differently.
Hello. I updated my T to JellyBean two days ago. I turned auto-brightness off because I thought Sony changed something and it's was working differently - the screen was always as black as possible just like there was no light around me. I just checked Service Menu and Ambient Light Sensor data. Result? Constant "0" value wherever I am - in dark room or outside at direct sun. Do you have the same problem too? Maybe JellyBean breaks ALS for now?

Mine says 0 as well, but i have no problem with the display, auto brightness works.
Are you saying auto brightness is broken on your phone?
Odp: [Help] Broken ALS on JellyBean?
Ummm yes. My bad I should have described it better. Yes I think it's broken, because ALS always shows "0" so the screen dims to the minimal value and it's totally ureadable outside with auto brightness turned on. When it's turned off it's ok, no problems at all.
I had no problems on ICS, auto brightness was always turned on and screen brightness was always set to the value where on the brightness widget that sun icon is "off" so it could adjust itself. And I had no problems in dark rooms where the screen was "correctly" dark and outside where it was very bright. Without manual messing with the brightness.

ok,
does yur screen change brightnes when you turn auto brightness off in settings?
Odp: [Help] Broken ALS on JellyBean?
I have it turned off now I couldn't use the phone because screen was too dark.
But yes, the brightness changes:
Turning AB on = brightness does not change at all. After turning screen off and on brightness drops to the minimum like I was in a dark room.
Turning AB off = brightness gets back to normal just like it's set.

Same for me, auto brightness act strange on my device too. When I thick "adjust brightness" sometimes nothing happends, not every time but it's not normal...
I'm just wondering, on ICS/JB, under brightness, mine had 'Adapt to lighting conditions' but I was still able to adjust the brightness :/
Does yours say auto brightness or adapt to lighting conditions?

Adapt to lighting condition/auto-brightness... In Polish it's "Dostosuj do oświetlenia" so in English it's "Adapt to lighting conditions" but commonly it's just called auto-brightness. I think it does not matter, we all know what's going on
Simply said - the tick option above the bar which you can adjust...
Constant "0" value read by ALS makes my phones screen always dark with auto-brightness on. Period On ICS there were no problems because ALS was working correctly.
EDIT:
I'll try to record a video and post it on youtube to show you my problem.
AW: [Help] Broken ALS on JellyBean?
Same here...auto brightnes act strange on my device with JB.

Thread can be closed - problem solved. I did a total wipe (formatting every partition except the ones connected with sdcards) in CWM and reflashed the FW. Then, after booting the device I did not check the option with restoring my saved data (Wi-Fi passwords, Settings settings etc.). The problem is gone but still auto brightness works so different when compared to the ICS one.

My phone does show ALS value of 0 as well.. but auto brightness seems to work..
ALS value = 0 for me too!
Brightness increases but not decreases until the screen goes off...
I got back to ICS and ALS works fine!

Yeah you are right. I can revive the thread somehow for any other people here. Also for me because auto brighness does not work again
But I don't care. I use manual brightness for a very long time and I got used to it. No annoying screen flickering and any other stuff
Autobrightness works, but a little different way than on ICS. ALS looks like it's off, but als_results file gives different results in different light conditions and the screen brightness really changes.
But sometimes the sensor stops working for some reason and you have to reboot to repair it. This happened to me between 2 or 3 reboots after fresh install of rom and now it's fine. (maybe a problem with illumination service).
But don't forget that the screen brightness is affected by thermal throttling and values from factory are very low. I think about 50% brightness at about 45°C xo_therm temperature.
I prefer ICS way...
it also happens in Xperia V JB ..
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.
It seems that AOD brightness level is automatic and can not be adjusted. It's even not connected wit screen "Adaptive brightness".
Is there any workaround. Do you think that this mod will work?

Make a backup of your device and give it a shot. Worst thing that can happen is it doesn't work and you lose nothing.
