Anyone else's auto-brightness not working? Mine doesn't
how?
How do you know? Or what have you noticed?

I don't think that mine works either, one of the first things I noticed.

Well it never seems to change. To confirm I put it on the lowest and then on auto, it stayed on the lowest. I then tried putting it on the highest setting and then putting it on auto but again it stayed the same.
Surprised it took me so long to realise..
It takes an average reading of the light it senses over about 30-45 seconds when it's on auto and responds accordingly on mine. To check yours put a torch on over the sensor for about 30 secs and if nothing changes yours definitely isnt working properly. However I normally have it set to a manual amount instead of auto to save on battery etc.
Edit: Just tested again with a torch and this time it took 45 seconds to change... odd.
Where is the sensor located? Does it use the front camera?

It's the thing just over an inch to the left of the front camera.
I see it now. I put a bright LED flashlight over it while in a darkened room for a couple minutes and the screen did not change brightness. However, it does appear to have an IR filter over it, so maybe it is mostly sensitive

With it on full brightness (before changing to auto) I had my finger over it for a while but it didn't change. Then I left it on full brightness for about 10 minutes in a fairly dim room and no change either.
Just tried with an led torch here as well and it did sod all this time. Nothing changed. Try with another light source if you get the chance. The update rate on the auto setting is too slow really tbh. There are loads of apps in the market to test the sensors too btw.
@Case0
If it's not on auto mode it wont change at all.
Possibly it only checks at certain times, such as when an app starts. I bet that it reads IR so only certain light sources might work.

I installed a couple of sensor tester applications, and none of them can report a value from the sensor. Sensor list 2.1 detects the sensor as a lite-on al3000a ambient light sensor, but no value is returned. Not sure if this means that it is not working, or if these apps just can't read that particular sensor.
It doesn't work for me either, although I haven't tested it since the new firmware upgrade. Maybe we have a bad batch.
I never was a fan from autobrightness. I always set it to middle.
Until I got a Nexus S and noticed how awesome it is that it changes the brightness, since otherwise you can not read the display outside. It also changes instantly.
Try this. Download and install Advanced Task Killer, then Sensor Test by Atmoworker. Kill all processes to make sure the sensor isnt in use by something else. Then run the sensor test. If your value for the light meter doent move, then there's something wrong for sure, or it's in use by some process that wasnt killed by the task killer.

OK. That app does seem to read the sensor, and it does change. I didn't have to kill any tasks for it to work. It gives three readings labeled 0, 1 and 2.
0 changes from 1.0 to over 100 outside. Probably some log scale. 1 changes from -27 to over 100. 2 sits at a very small number, about 10^-45
So the sensor does work, the tablet just isn't using it properly it appears. Or something.
Ok well yeah sounds like it does work, just doesnt function the way you want it to. There are lots of apps to deal with screen brightness on the market, some free, some not so. And then there are also a few which lets it change using the camera instead of light meter. Here's a link to one to show you what I mean. https://market.android.com/details?id=org.pbxes.light2&feature=search_result I'm sure there are free versions available if you do choose this option. Good luck in finding one you like.
Well, if by "just doesnt function the way you want it to" you mean does not do anything at all ever no matter what, then yeah, it isn't working the way I want it to. Thanks for the tip, I'll see if I can find an app that works.
OK, auto brightness DOES work. I spent some time messing with it to figure it out. The auto routine started working after I did the 10 second power button off on my machine.
1) The level that you set with the slider becomes the minimum level for the brightness under auto. That's also why I didn't think that it was working, I had brightness up all the way.
2) The auto routine will adjust brightness UP within a short period of time, 10-15 seconds, if you move into bright light.
3) The routine will NOT adjust brightness down (you move into dim light) except at three points a) right before the screen saver kicks in (goes blank) or b) right after returning from the screen saver. c) you power cycle the tablet.
This means that it is quick to respond to ambient light and increase brightness, but if you have your screen timeout set long, or you keep using the tablet, the brightness will be very reluctant to adjust down. The brightness will never be adjusted lower than you set with the slider though, but it can go up all the way.
If any of you other users out there feel that the whites on this thing are too awesome for super late at night like I do, I found a app when searching for a f.lux type alternative for android. I have been using this app to help ease the stress on my eye late at night. I dont know about the techical side of what it does, or any of the jargon involved, but it applies a filter of sorts to dim the screen further than what the phone allows. I been using it a lot lately and figure I would share with you guys. If anyone has any recommendations for other similar apps, please share.

Or just turn on "Background Color" in Power Saving Settings.
Or if you want the screen brightness itself to be lower than what most ROMs allow, you can use this app called RootDim. It worked amazing on my xoom, not sure if it works on the SGSIII yet..
It requires root though..

Screen filter does the same and doesn't require root. On our AMOLED screens this can save battery.
Also you can turn off those damn capacitive key lights by going to Settings>display>"touch Key light duration"> Always off.
I can confirm that Root dim does work for the SGS3 I use it on my phone.

Lux is an amazing auto brightness app and setting it up for your tastes is incredibly simple.
Go out in the sun and turn brightness up all the way using the app then "link" that setting, go in complete darkness and set it to your taste and link it, then indoor lighting, set it, link it. It then uses just those 3 settings to create a smooth graph of brightness values that are all perfect. You can have as many links as you want but i find the less settings you put in that app the better.
I tried all the suggested ones in here btw.

I've tried and really like Lux (in fact I'm considering purchasing it soon) but I've noticed two issues. First is that sometimes it will not refresh itself and I have to open up the lux dash to get the brightness to change. It doesn't happen often, but it happens often enough to be annoying, and I have it set to automatically.
Also, (and this may simply be an issue with the S3 and not lux itself) but sometimes I will be in a decently lit room and be at 1 lux, while lights out is 0. Not a lot of variance unless it's really bright outside. Have you found anyway to increase the light sensors sensitivity?

Try setting it to be always active in the task bar, that prevents it from being killed. Also try setting it to not use raw values for light sensor readings, this gives you a simple scale of 0-10 for readings and total darkness always reads as 0.
Edit: oops reread your post. That's weird that it is reading indoor light at 1. I usually get around 2 or 3. I used to have a screen protector on that covered the light sensor and that put it all over the place. Maybe that is what's causing it?

I noticed the same behavior with the free version. In my case, the lowest value the HTC Desire S can reach with its default Android auto brightness is in fact about 15%.
In LUX settings you can configure the "0" value to be lower and "bypass" the freeware limitation (you can't configure sub-zero levels in the free version). This will work when you test it in the dashboard, but during regular use the light level never goes below the 15% limit already set by the OS.
What I did was purchase the full version (to get astronomer mode along with all the settings unlocked) so I was able to leave the 0 level at its default 15% but link some light intensity values to sub-zero percentages. Guess what? It works great! Once you go into a very dark room, the display dims as far as you set it to.
Another problem with the free version was that a few times I unlocked the phone outside in full sunlight and LUX did not increase the brightness. It appeared almost completely black because the light level was at about 15-25% (the same level it would be inside a low lit room).
Again, with the full version I did not notice this problem (I've used the free version for 1 day and the paid version for 1 day but running tests in different light levels inside and outside).
It's like the free version is a bit buggy on purpose, and I remember uninstalling LUX free about 2 months because of this; I was thinking that if the free version does not work OK, I shouldn't buy the full version. Apparently this is not the case (touch wood).
Just for the record, it's on "dynamically adjust".

If the display is a bit dirty (oily, dusty, etc) around the light sensor, you can try to clean it. If this is not the case, open the dashboard, let it determine the light level or hit "auto" a few times and make sure the reading is correct. Then just slide your finger along the yellow line to find the appropriate brightness level and long press the chain to link. Go to a brighter lit room then go back to the first room and see how LUX behaves. Also lock/unlock the phone a few times and see how it goes.
If you still have problems running LUX, disable it and check the default Android auto brightness to make sure it's not a sensor issue.
LUX also has the possibility to set the response delay under Settings -> Advanced -> Developer Settings (the last to just on the bottom, but for this you would need to buy the full version.

Thanks, but I think it is more of an issue of the sensor not being sensitive enough. I'm not sure if this is anything you can change in lux or if it would have to be edited in the kernel (or if it is fault of the hardware) but I just feel like the sensor doesn't go down low enough. As I said, I can get down to 1 or 0 in a decently lit room, and yes I have tried cleaning the screen. It's not like it jumps around or anything so it's not like I would notice anything in default auto brightness, it's just that it doesn't seem to be sensitive enough.
Screen filter is great!! I use as well!!!

Well for my Desire S, the lowest light level that the sensor can read is 160 lux (raw value). You can try and set LUX to use raw values because this is more accurate in my oppinion.
Another +1 for Screen filter here
Does anyone know how to use "luma" values for automatic adjustment in Lux instead of "lux" values?

What I have noticed on my phone is that "luma" readings are taken from the front facing camera, while "lux" readings are taken from the ambient light sensor (you can chose which one to use in the settings).
I suppose the front facing camera uses more battery than the light sensor; it also appears to be more sensitive because it can read more light levels.

I guess so. Thanks! But doesn't that kinda defeat the whole purpose of Lux? Because you can't use automatic mode with the camera(s).... so then what's it good for?
Well even if you don't have an ambient light sensor, you can still use the camera to check the light level when you unlock the phone and let LUX adjust the brightness level. Of course it's not dynamic but it's still better than having the brightness at 50% the whole time or changing brightness levels through a widget..
Not sure if this is a Nexus5 or Android issue ...
Not sure if this is because I'm moving from an AMOLED to a IPS LCD ...
but I find the Auto-Brightness less of a function and more of a roller coaster ride.
- At home, in a well lit environment, the phone defaults to max brightness, which doesn't seem correct.
- In a dark room, upon wake of the phone, it correctly selects a lower brightness, yet will randomly ping up to max brightness, then settle back down.
The screen on the Nexus5 is absolutely gorgeous, but it just can't seem to select and lock onto the proper brightness level with respect to ambient light.
Is anyone else experiencing auto-brightness wonky-ness? Are there any potential fixes?
Everyone AFAIK suffers from it on nexus 5.
I have a horrible feeling it's a hardware fault, as none of the other Google devices on kitkat have this issue.
yeah the auto brightness seems to be too aggressive, but i'm sure custom roms will have the ability to tweak the auto brightness settings. i think even gravity box has some tweaks for the brightness
If you download Android Sensor Box, you can check the Light sensors. I think it may be bugged with Halogen lighting (correct me if I'm wrong). My home is ~ 18 years old, and we have some bulbs that have not been changed yet (yellow). Sometimes when I use my N5 under those lighting, the sensors go whack and don't register properly picking up 0lx, then spike up to 30000lx. Once I move to areas in the house with newer bulbs, the sensors work normal, picking up the right readings. I'm not sure if it's a rom issue or hardware issue, but my cousin also has a N5 and his worked fine. I tried flashing a new rom and mine still acted up fresh after boot (1st app installed after fresh flash was Android Sensor Box to test).
As a rule I don't use auto brightness. Just get something like lux or install exposed and enable a mod to let you adjust it by sliding your finger across the notification n shade. Easier and faster.

I find that autobrightness will auto-turn on, even when i don't want it to.
There is something funky about it, I can either make the phone too dark (using lux) or too bright (using default settings)
I'm still not happy.
Tried Lux, tried adjusting the brightness tables via Gravity Box, used Twilight (to dim at night), no matter what, N5 just wants to be at full brightness all the time!
I had my Nexus 5 in the cinema the other day. The phone was sat in the cup holder by the chair for the most part of an hour when I quickly replied to a text. On turning the screen on it was on full brightness and what's worst is it took around 10 seconds for it to go down. There is definitely something not quite right with it.

Hi, I have been experiencing this as well, so I attempted to fix this at ROM level. The solution requires Xposed framework, so it works only on rooted devices (related discussion).
Hi all, after updating to Android L (5.0 and 5.0.1) I've noticed that the ambient and proximity sensor will stop working after a certain amount of time. The time appears to be random at the moment. It started off with the adaptive brightness not working correctly, it would always be near max brightness in the dark and minimum in bright light, and at some points it would just stop changing altogether. So I decided to get lux autobrightness, it works better than adaptive brightness in L, but it would also stop adjusting itself after awhile.
Then I noticed that sometimes during a phone call, the phone's screen will not turn off so at the moment I decided to check the sensor's value with an app when the auto brightness/proximity wasn't working anymore. Turns out that the sensors are all registering 0 values or not changing it's readings despite being in different light conditions.
A reboot fixes this but, it's really annoying having to reboot the phone once a day.
Anyone else experiencing this?
EDIT: nvm, found out that other people are experiencing this as well. Haven't been on xda for awhile and forgot how to use the search button
When auto brightness is enabled and I'm viewing the phone in direct sunlight, the maximum brightness seems to change really quickly. It brightens and dims quickly, almost qausing a feeling of screenflicker.
With auto brightness off, the problem is non existent.
It only happens when the phone hits 100% brightness. Anyone noticed this. And is there a solution other than turning auto brightness off?
Yes I noticed this today just got mine today and sat out in sun with auto brightness on it was flashing like mad ,

For me autobrightness is useless. Simply too dark in all conditions. Also max brightness is not enough for when you have direct sun on the screen.

I have noticed the same, it's usually too dark for my taste.. would be nice if you could config how dim it goes automatically.
O saw the flickering in sunlight as well. Probably a bug
I finally gave up and installed the Lux app. Hopefully they will solve the issue in the next updates.

You're all insane. This phone has the best auto brightness I've ever used. It's very responsive without changing so fast that it becomes an issue in flickering light conditions like walking past trees where sunlight filters through or something.
I have the same problem, yes.
OLED displays have two "maximum" brightnesses; the normal maximum, which is intended for full-time use, and High Brightness/Sunlight Mode, which maxes the pixel brightnesses out for temporary outdoors full-sunlight usage.
The OP6 might have the threshold for what it considers "full sunlight" set too high, which would cause a lot of flickering in the event that the phone isn't held perfectly still in sunlight because of the light sensor output dancing back and forth across the threshold.
There's probably no changing it until someone rolls out a custom kernel in which it can be disabled or tweaked, in the meantime you can find auto-brightness apps on the Play Store that let you set custom curves (note that this'll probably require root). Hopefully OnePlus will fix it in the stock kernel themselves, terrible auto-brightness can make or break a phone in my opinion : \

I would not hold your breath. It was an issue on the 5t and not sorted during the time I had it.
Can't say I've noticed the issue on the 6 though with adaptive brightness mode enabled
Couldn't agree more autobrightness seems too dark on my op6. Under direct sunlight, I have to disable auto and full the bar myself..
Auto-Brightness is too dark for me too... Hope OnePlus will be updated this, or add the possibility to adjust the Auto-Brightness.
The minimum auto-brightness can be adjusted from the slider, it will still be auto increasing when needed but it won't go below your threshold.
I'm testing this for a few days and it's working perfect, the minimum was also to low for me initially.
I've tested the auto-brightness with a flashlight:

EVERYONE WITH BRIGHTNESS ISSUE,
There are No problems with screen, it's flawless.. Although people dealing with auto brightness issue,should disable the night mode.. Cause when night mode is active, auto brightness tends to use more dark screen as dark as possible..

Actually I like yellow tinted screen(warm colors) , for that I enabled night mode. Since then I was facing problems like too dark in direct sun on auto brightness. Too dark even in room. Today I accidentally turned off night mode while showing handset to my friends.. And voila brightness got up nd up nd up... I tried in direct sunlight, now I don't have any problem viewing my handset even after wearing shades..
If there is still problem in ur auto brightness then bro I strongly suggest u to compare ur handset with other op6 cause it could be a manufacturing defects... I heard a developer got flickering issues, he returned handset..

I have auto tightness issue also. Have not noticed flashing, but screen dims often. Even when using phone, and in a steady lighted area such as indoors.
