I searched the whole internet, but can't find any solution for my problem.
I have auto brightness enabled, but it only works one way. It's highering the brightness but then, when light conditions are darker it doesn't dim the screen down but it does turns off the lights of the capacitive buttons and keyboard...
How can I get this device lowering the brightness automatically?
Can someone help?
I am running stock, deodexed, rooted 5.7.894
Thanks in advance!
Try running a different ROM. I think the 894 was the original ROM.

5.5.959 was the original, IIRC. 5.7.894 was a leak that was never pushed OTA. 5.7.906 and 5.6.890 are the only pushed OTAs, 5.7.906 being the latest. Go Settings > About Phone > Software Update and DL the 906 OTA.
Erhm, ... thanks for your advice, but it's not my intention to update the firmware due to many mods I applied which are not working anymore in 5.7.906, the Atrix Camera and FM Radio app for example...
Can at lease anybody confirm this auto brightness behavior?
Autobrightness works fine for me. Rooted stock 906 on XT862.
Do you have something covering the light sensor in the upper right? To the left of the camera and LED?
Autobrightness works for me too, BUT its just highering the brightness, it's not dimming when it gets darker.

I guess I should have been more clear - autobrightness does both on my phone, so the functionality is running fine on my stock, rooted 906. In fact, it has always been fine on my phone.
Since you are rooted, you could try a few things: install Clockwork Recovery, or Safestrap recovery, if you have not already, and run a Nandroid backup and then try a factory reset to see if that solves the issue (if it does not, that was the point for the backup; you can then Nandroid restore back to where you are now.) Or you can use Titanium Backup to backup your third party apps, try a factory reset and them use TiBu to restore apps to get your apps set up again and see if that solves the problem.
Not that it helps you much but I've ways had issues with auto brightness on my phone, regardless of rom. Fastboot flashes don't fix it either.
And now that I think about it I don't think mine dims either.

Well, that's what I was thinking, too. The last time I really know that auto dimming worked was on my Milestone 2. I did as doogald sugessted but it doesn't work.
I have put so much time and effort into modding my 5.7.894 that I won't upgrade to anything, except of ICS if it's ever becoming stable.
But I appreciate any hint or information sharing.
Thanks.
notice the scratch-retardant screen cover that you affixed. the transmittance of some screen covers are low. so, i digged a pore on the screen cover above the light sensor
Sent from my XT883 using xda app-developers app
cstn makes a good point. Some GNex users have reported issues with proxy sensors detecting the screen protector and never waking the phone, so the same may be happening with your light sensor in some form. If there is a screen protector covering it, I would trim that area away and test.
Same problem with rooted stock Bell XT860
I have been having the same problems with auto-brightness getting brighter, but never dimming. I am currently running what appears to be a stock Bell 5.2.476 (2.3.6) which was rooted before I bought the phone. I installed a third party application to do the brightness control as a workaround, but so far it is a bit annoying about changing the brightness levels excessively. I suspect that some fine tuning will fix that.

Sensor works but won't dim
I have the eclipse rom and it won't dim either. It's supposedly .906 and I even tried adjusting the levels too. My car app will auto dim when it's running.
http://forum.xda-developers.com/showthread.php?t=1235212
Does anybody know what code is responsible for auto-dimming? Is there a System app that does it? My phone is rooted, so it would be nice if I could find a way to replace whatever is doing the auto-dimming with something that works. I have an app that does it, but it takes over the brightness completely, so there doesn't appear to be an easy way to manually set the brightness temporarily while it is running
I always wonder how open an operating system is when such settings are NOWHERE to find, wheather it's the speaker volume, or brightness settings, or lockscreen or anything. It's almost like Symbian.
Well, hate mode off
I'd also LOVE to know where these settings are stored.
My Car Dock Home app will auto dim when it's running and only when docked, so maybe it will help someone that knows a lot on how these apps work. My wife's droid 3(same as mine) does not auto dim either and she's is running official .906 rooted and I tried several roms (Eclipse 2.2.2, Eclipse 3.0, Liberty 2.0) and no luck.

The OS is quite open in most cases, given sufficient time I could find it in the source code. The biggest openness-deficiency is in the area of device drivers. Generally the source code for drivers for things like cameras is not available, which is why it is quite common to see new ROMs with broken camera support
Since I can't post on a developers thread I figure I would post it here. This is my setting for the droid 3, I modified the Lux (config_autoBrightnessLevels) values for the first few to allow the phone to dim completely in the dark. A lux value of 2 is when you completely cover the light sensor, so I set it to 3. Lux of 10 was with my small lamp on, 20 was with my ceiling light and outdoor but not in the sun is about 4000. I still can't figure out what setting causes the dimming, but I don't think it's in the framework-res.apk

A few days ago I started to use the Automatic Brightness, but it doesn't worked very well...
When I am in bright area , the brightness increases, but when I leave the area or cover the brightess sensor, the bright the screen should change his intensity, but he remains the same, at high brightness. The brightness decreases and becomes what it should be according to automatic mode only after lock-unlock screen.
Anyone can help me?
I think the sensor dont have problem.
I think if you check the option "Display -> Brightness -> shade bright screens" (or somethink similar to that, i have to translate) it could make it work properly. A broken brightness sensor doesn't control anything anymore, my old DHD had one.
i think its a software problem
Same problem on my razr i
But on some razr HD, there isthe same problem. Maybe the software version....
I use "custom auto brightness" apk on market, and work great for increase AND decrease brightness.
For information, same problem with JB 4.1.2 update...
Anyone have the same problem and a real solution ?
::/
Thanks this app worked very fine!

Just use the app lux auto, my brightness sensor was working ok but it always too much bright wasting battery, after installing lux auto and understanding how it works i have to say its perfect now!
Seems like my phone has forgotten it's amoled. It lights up the entire screen even if it's just black. The screen is overly bright and looks washed out and I can see tons of imperfections on it that seem to move with whats on the screen. This leads me to believe it's software, (happened a few days after a cm12.1 install) .
I've tried flashing stock images and it still persists. Anyone experience something like this? Not sure the best solution.
lower your brightness? what brightness do you keep it at?
Regardless of whether brightness is 100% or 0% the screen is overly washed out. It's as though the backlight is being turned on even if there are dark pixels on the screen. Everything is just way brighter and hard to read. Not sure if it's a hardware problem or software problem. Any way for me to determine this? Only thought would be a nandroid backup from my phone being restored on another to see if it recreates the problem but i don't have access to a second nexus 6.

Can` t you go to store where they sell the Nexus 6 to compare? I reccon you`re on stock and don`t use a custom kernel for color control, my screen is beautiful imo. But also its possible that maybe you have a faulty device, it can happen ....
My screen was great. It's a recent issue that came up. It has happened in the last few days.
This is my first Lollipop device after a long time with Kitkat, so I may be missing something obvious, but I just can't wrap my head around Adaptive Brightness.
So when it's set to on it adjusts the brightness based on the light sensor, but I can also use the slider to tweak it, correct? But then sometimes the slider just stops working, moving it doesn't change the brightness at all. Only way to make it work again is to change the lighting significantly (for example I point the phone at a lamp). After the auto-adjustment kicks in I can tweak it with the slider again. Is this a bug, or yet another misguided "feature"? Do I have a hardware problem? I've tried a few sensor apps and everything seems to work fine. On top of the auto adjustment not being as good as Kitkat's, the inconsistency is really bothering me.
EDIT: I am on stock rom. I'm sure that CM12 would solve this problem if it's a Lollipop bug, but I can't be arsed with a custom rom a this time. Looking for a stock based solution, or at least an explanation for this strange behaviour.
Off late I'm noticing that whenever I turn on the display, it goes completely bright for maybe 5 seconds before adaptive brightness kicks in. Today I completely reset my phone and reflashed the latest factory image (MRA58R, I was on MRA58N previously). It was fine for a while (for a few hours) and now it has started behaving the same way. It works fine if I turn off adaptive display. This happens 90% of the time.
Has anyone else faced this?

I have filed a bug report, please star it.

I've got the same issue on 6.0 stock not rooted. I've been fiddling around with lux trying to get it to stop going to max bright in low light settings... And it seems that the light sensor is getting incorrect readings in low light and it takes a few seconds for the sensor to start showing accurate levels for the light conditions. I would love to have adaptive brightness work as it used to - don't know what changed.
Same issue here.
Woah. I'm not alone. So for all you guys, it started just recently?
yeah. I noticed it a little less than a week ago
Do you use Gravity Box?
Issue came with that mod for me and even after removing it my Adaptive Brightness still doesn't work properly.

Nope. I'm running completely stock, no root, even locked bootloader (for device protection feature).
I am running completely stock marshmallow no root, boot loader is locked, no gravity box. Same problem.
Is there any program we can use to monitor the readings at the light sensor is receiving?
I have tried two apps but that doesn't seem to gather data while running in background; only works when the app is opened. Still trying to find one that does background logging.
I have the same issue.
And I thought it was Gravity Box.... now I wonder if it's the November patch? Since there is report from people who never root and using stock?
Ok, so I found an app that can log data while in background. It's called Androsensor. It also has a companion app (Androsensor Keep Awake) which helps to hold a wakelock to gather more data. I tried it and I feel it's definitely not the sensor or it's driver/binary malfunctioning, it seems to be reporting proper values. Maybe more people can try it and report back.
i just bought my phone (brand new) update it right away to 6.0 and used it and having thesame issue!
that means this is google firmware problem!
The reason I believed it to be the sensor was because I used lux to try and fix this and noticed when the bug was occurring, as the screen just turned on and went to max brightness, lux showed the values from the sensor above 20000. Oddly enough if I had lux update every 3 sec it would sometimes capture the actual light levels on the second update and adjust accordingly. I'll check out the app you mentioned and see what shakes out.
I'm having it too, also completely stock and unrooted, first noticed it a few days ago. A friend of mine also has it. He is also stock, I'm not sure about his root status though.
Ok got some interesting results this morning using androsensor. First of all I was unable to recreate the bug while using the keep awake helper app... Which leads me to believe that there may be some issue with the sensor values being calculated/averaged by the autobrightness code/program as the device wakes up from sleep. perhaps android is shutting off the light sensor when the device goes to sleep and this causes a reset? So it appears that it's not getting wrong values rather, that the data being drawn from the sensor is reset or perhaps recalculated as the device wakes back up. Almost as if it can't remember the last light level that was observed. I uninstalled the wake lock helper and was able to recreate the bug by letting the device "sleep" (leaving the screen off for maybe 5 seconds). So while the sensor showed readings of 2 lux the screen brightness was increased erroneously until the auto brightness refreshed and then after a few updates on the sensor the correct brightness was applied to the screen. Curious results. Can anyone else try to recreate the bug using androsensor and the wakelock helper program? I'm hoping I didn't run into some user error there.
I too tried without the wakelock helper and got the same result which made me believe it's not the sensor that's causing it. Will try the same with the helper app and report back.
Just tried Androsensor with the helper and I was unable to reproduce the bug, exactly what foxnutz faced.
Alright so we got some results! Just for the sake of being thorough, can anyone else replicate these results that andr0idfreak and myself saw? It seems holding a wakelock on the sensor stops this bug.
Now where do we go from here? It's been an awfully long time since I've done anything with logcat... But I think that may be our best bet to find out what's really going on here. I'll have to do some homework before proceeding. Will report back.
I think we should file a bug report here.
https://code.google.com/p/android/issues/list
I think a bug report is probably worthwhile. I thought it was some combo of xposed and gravitybox as well but I flashed my stock system back and it's doing the same thing.
title says it all, why is this hidden and can only be accessed thru settings, and it's not a one time toggle, you'd have to go into settings every time you pull your phone out. just why? would be great for the brightness slider to just go to max instead. anyone know if theres any mods for this? or just what this is about, seems strange.

Mine always stays where ever put the slider. But then, I have auto brightness off.
Yeah what version you got? Wish we had outside mode.
I have a 950F exynos 128 GB, and It does not have such setting...
Because it's samsung. They will probably never make a good software. Just search for "automatic brightness bug". They just ignored this problem. No wonder they just hidding that option.
Outdoor mode can be enabled by editing something in system folder. Most of custom firmwares provides that function.
I've never seen that setting on mine. It's automatic for me.

IT is not a bug, and yes, there are ways to increase brightness beyond standard maximum, I remember from the days of my note 3, that many people posted very bad screen burn in and excesive batt drain when changing the lines to attain the most bright screen possible, same applies to speakers, might as well get blown, The auto brightness in note 8, in fact is very well implemented, because it learns your preferences, that is, if set to auto, and you move the slider, whenever the phone detects the same lux level, it will set the level you chose, infact, when in autobrightness, when sensing too much light, it will set an extra ammount of brightness

Agreed. Works very well. Was using GPS Google maps for the first time yesterday, screen was automatically too bright. I used slider to lower brightness, it learned my preference.

Since long I haven't seen any Note device (at least International versions) have Outdoor mode enabled by default unless you are using custom ROM. But this mode i have seen available on low range samsung devices. Actually it is hidden and one minor change in settings app enough to enable outdoor mode.
I will try to make small app without making changes in setting app, though it might needed root access.
Thank you dr ketan! I have used your excellent roms and kernels in my note 3 and 4

hey something cool came out of this post, awesome!
so the app acts like a toggle to turn on the outdoor mode, pretty cool!
Works perfectly. Thank you.
Have noticed this mod seems to time out after 15 minutes or so. Any workaround for this?
@ dr.Ketan: since updating to oreo your app does not work anymore... do you have a solution?
THX in advance!
I am on oreo too and working fine. Check you have granted su permission
