When adjusting brightness with the slider, it doesn't change. There doesn't seem to be a auto brightness setting and I have tried a few brightness apps and it still doesnt change. Screen is quite dim.
Currently rooted and on nexus rom.
Any suggestions?

Known issue with this device; reboot will fix it. No fixes (likely a kernel glitch) that becomes more prevelant when device is heavily loaded.

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.
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?

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.
Just picked up an ME572c and I'm very impressed for the price. However I have noticed the screen brightness levels keep fluctuating as if the light sensor is constantly detecting different light levels.
Has anyone else experienced this?

Hi,
i notice this too, but that can be related to the power saving mode. Plz turn it off and check the settings in detail. Maybe that helps.
Further inside the developer options there is another option to configure the auto brightness.
You can change the behaviour from dynamic to immediately or slow mode and active an onscreen lux, gain and brightness value display.
Btw i am not satisfied with the auto control, as for my taste the brightness is still too low in a less lighted room. Sensor is reporting 0 lux already with a brightness of 14 which would be ok for a really dark room & night but not at daytime.
What is your experience?
I tried playing with power saving mode and the auto brightness controls in developer options. While I could reduce the fluctuations, I could eliminate them completely. Unfortunately I found it too distracting and returned the device earlier today. It's a shame as everything else was quite impressive for the money.
I also found the fluctuations annoying, my solution was to turn the auto-brightness off. Honestly I dislike auto-brightness on any device, it was also one of the first things I turned off on my laptop.
I am using Lux app now and raised minimum brightness at 0 lux. Thats ok for me now.

Just bumping this to confirm this works and so that others can see. I used Developer options as well (before I found this post) and noticed the instant setting works best.
One more setting to also double check... Make sure that in developer options under auto brightness that you disable allow change gain...
Even with everything disabled it appears as if something still is changing the display. I particularly see it with something like a reddit browser when I'm viewing pictures. You click the pic, it loads and displays and then 1-2 seconds later the display adjusts based upon what is being displayed. Depending upon the picture it can be pretty annoying. I may have to root and start poking around to find out what is causing this.
with the lollipop update this issue is fixed for me.
Is lollipop really solve the problem?

Hello!
Im on lollipop, but the problem you had, still occur at me.
Did you noticed this problem, since you on lollipop?
I have the same problem. When i read, or browsing, the brightness changes in 2-3 steps.
Good evening,
just wondering if anyone else has issues with adaptive brightness after the latest PIE update? Since the update it changes the screen brightness during low light conditions from semi-low to low without any reason. And in normal light conditions it sometimes gets way too bright. And it doesn't modify the screen brightness in small steps but in one "big" step.
Btw: I did not wipe my phone before upgrading, maybe that's part of the issue.
yeah same issue here. phone seems to wake up in very low brightness mode randomly?
same here.

You will have to go back to the display brightness and adjust to the level you like, then subsequent light condition will then be adapted to your new value.
Hope this helps.
Same here. And I did full reset, after Pie upgrade
