do you guys know how to or what apps can change the auto adjust level? and please dont say just manually change it, i like to use the auto feature, its there so i can be lazy.
Settings > display > brightness

You can go to settings> display> brightness and set it to auto brightness, or you can get the app "Quick Settings" it has a bunch of toggles

I think the OP wants something similar to what's in Cyanogen roms. I think he wants to adjust how bright or dim it gets on certain light conditions. I think I saw an app called Luminous or something. Now I'm drawing a blank.

Maybe if you found the file that holds the values, you could pull and push the file till you find what you like?
EDIT:
Try this, maybe this will work. I think this is what I saw once.
Lux Auto Brightness

I think I might give it a try later on.
Juice defender has an option to set the brightness all the way from -80% to +150%. So autobrightness would have a larger (or smaller, if you prefer) range.

Have it. Recommend it. Slick app from a great responsive developer.
just use the notification bar
Hey guys
I found out that if you tap the notification bar on the top and slide your finger left or right, you can adjust brightness as you like. I think that is the easiest and quickest tip I found on this forum. not sure where I found it.. hope that helps..
^^ only works if the brightness toggle is off.. Awesome feature on sammys..

There is an app i am using that allows you to adjust the levels that the auto brightness use.
Called: LogGraph
it gives you a graph divided by roughly 12 steps of the brightness sensor so 0-12.
you can set the brightness level at each step the default (which i am using) is roughly:
Sensor% - Brightness level%
0-0
10-5
20-10
30-15
40-20
50-25
60-30
70-40
80-60
90-80
100-100

Thanks I was wondering why it didn't work.
Sent from my Hercules using XDA App
Reviving a slightly older thread here for some feedback.
Lux is a great and well designed app; I've been having issues with it - it doesn't seem to sample from the sensor (light or camera) when it wakes up, even though that is how I set it. I sent an e-mail to the developer, so hoping he can help me out. I also found it hard to understand the "levels" both in basic mode, and the lux/luma in advanced mode. I came from Cyanogenmod (on an Evo 4g) so I understand how the sensor works, but for some reason, whether it be the GS2 or Lux, the sensor does not seem to pick up a lot of variation in ambient light. I can cover up the sensor with my finger and the value that is getting doesn't seem to go below 2.
So I'm still struggling to get the auto-brightness (with an app or with the factory algorithm) to work properly compared to what I was able to get on my Evo 4g w/ Cyanogenmod (which was perfect by the way - once I have it all set up, absolutely perfect auto-brightness).
Actually I edited the framework-res.apk file and that did the trick. I tried lux before but it still didn't work like the default auto brightness.
I'm just sayin!

I'm guessing this is something that can't be edited live or on the fly? It's got to be signed and flashed?
If that works, cool, but I'm totally hoping for an edit I can make live to system files from Root Explorer for instance.

I believe you that Lux doesn't work like the factory auto-adjust...no matter what an app. developer does, you can't replicate the responsiveness of what would be in the framework.
Could you explain further the edits you did and what it corrected? I am a software developer and I can figure out the basics, just was looking for an idea of what you edited in there and the specifics to get me going.
Thanks in advance!

I basically followed what they did here http://forum.xda-developers.com/showthread.php?t=1235212 to decompile the apk. I made adjustments to the value that represents the brightness under the lowest lighting conditions. I slightly increased the brightness under that value to help mask the blobs under low lit conditions. Hope this helps.

Yeah, saw that last night and just finished. Will probably need to dial in the values a bit to find what is optimal for me.
I'll post a Framework for others to use once I get mine all set. This is definitely the way to go for adjusting autobrightness.
I know this is possible in CM9's display settings, but I'm currently running AOKP. Is there any other way to lower the minimum screen brightness?
I've given Tasker root permissions, approved it as a device administrator, and approved it as an accessibility service. Still, when I use a task to lower the brightness to very low levels, the brightness will only hold for a fraction of a second before it ramps up to the factory minimum.
So is there some system component I can modify to allow lower brightness, or is this only available as a ROM control like in CM9?

FWIW the lowest possible brightness setting can't be altered via the CM9 settings, only the auto brightness levels, both sensor input levels ("bins") and the brightness level associated with that input/bin. The minimum value of 19 for the lowest slot can't be lowered further. There are other display parameters (related to brightness) that can also be altered in the CM9 settings, but it won't accept a value less than 19.
Edit: I see from a link in your sig that you're familiar with the custom levels
Yes we can do it in the frameworks to go lower than 19. I did it on other phones. I'm not sure why it hasnt been done yet for nexus, and ive been too lazy myself.
But we can even take it down to zero or 4-5 etc so its much dimmer at night. Its on my to do list.
Also i posted some kernel code in a similar thread where this question was already asked. But mod the framework is much quicker.

I'm an idiot; I just found it in AOKP. It's in the custom backlight settings.
My experience does not mirror you guys. When I decrease the "screen dim level" in the custom brightness settings, it applies globally. I just did it in AOKP the same way I used to in CM9 and now with Tasker I've taken the screen all the way down to 1
Is there any way to decrease the minimum brightness on stock?

Yes with above linked app. I confirm it works on stock

I've used a similar app called Screen Filter. My only problem with these types of apps is that I find the black/gray filter they use greatly decreases contrast at low brightness levels (more so than a "true" brightness level at an equivalent setting). Still, if you are running a setup in which they are your only option, they certainly beat having nothing.
The problem with using a screen filter is that it limits the maximum brightness when in sunlight.
I only want to affect the minimum as it is too bright.
Has anyone been able to do this on a stock rom? I too think that the minimum brightness is too high, but I don't want to use the above linked program because it also affects the maximum brightness too. I would like to be able to set custom light levels as per cm9/cm10 and pretty much any custom ROM right now, albeit with my stock ROM. Any flashable zips out there?
Cheers,
Dan
I posted this before when all the SGS3 variants were under one forum. Now that they're locked, I just wanted to post this here as I know a lot of people liked the app. I use it everyday.
One thing I definitely miss on SGS3 coming from SGS1 and SGS2 was the ability to change the brightness setting from from the top of the notification bar. You were able to slide your finger left to right and be able to change the screen brightness.
Display brightness can do something similar and thought I'd share as I am sure a few of you might also miss the old feature. You can set a screen brightness slider anywhere on the screen and change its transparency. It works a treat to be able to change brightness quickly and efficiently. I set mine to be on the left side of the screen horizontally, and set transparency to 0 so it cannot be seen. Then when I need to change brightness quickly, I just slide the bar up or down. There are quite a few options and different sizes you can choose. Also, you can set it so that there is a one second delay. This helps to avoid touching the bar by accident and changing brightness on you.

Have it installed and really like it.
One problem I'm having is that I set it to Enable the Indicator on my screen, and it periodically turns off. A bit frustrating. But other than that, it's great.

I get the error trying to install apps every time I flash cm10 and then go back to stock. If that's the case youd notice it trying to install other apps on the market. Either case it's a market problem or the rom you're on. I normally fix by clearing market data as well as google framework data too. Then reboot and I can install apps again. It doesn't sound like an app problem though
Also the indicator shutting off I have not seen before. That could be a result of task manager app or something shutting it off somehow

I thought about that. If so, it is the system manager, because I do not run task managers.
I do have System Tuner...have nothing set in it's killer. I did set this app as excluded (which my understanding is that excludes apps from availability to kill). I think maybe it did help, but did not cure the issue.
Ultimatum rom lets you change brightness from the top. However the min brightness doesn't go low enough on this phone. Too bright in dark rooms

I use another app called screen filter for the darkness issue. Check it out! You can then make the screen MUCH darker depending on preference. I agree, the screen does not go low enough on this phone especially at night when in a dark environment.

I swear by this app. Greatest thing ever for texting at night or even (Yes I know, shame on me) in the movie theater.
My screen dim level is at 1 and my phone is still too bright. How could I reduce this even further so that sliding my brightness toggle in the notifications bar all the way to low will reduce the brightness even further? Is there not an option or a mod that allows you to pretty much dim your screen to complete darkness?

I see screen filter, the only problem I have with it is its persistent notification. As far as I can see there's no way to remove it. If I could get rid of the persistent notification I would set it to boot with tasker.
Suggestions to remove from notification?
Try lux auto brightness not sure if it has persistent notification or not.

Yeah I actually prefer the dropdown notification built into AOKP roms for brightness, but the lowest brightness is too bright. In a room with lights off, reading the amazon kindle before bed is pretty discomforting if you're trying to ease into sleep. Way too bright.
Apparently the only way to do it unless the screen filter author comes up with a way to get rid of that persistent notification/load on startup is to kernel hack, and personally for someone who isn't a developer/programmer, I wouldn't touch an opensource code with a stick
I have the same problem. The lowest brightness is still too high to read something with the lights off.
Hey, I think I actually found something.. do you have cm10? If you do, you can turn on screen filter normally then go to settings > apps > screen filter and uncheck "show notifications". That took away the persistent notification for me.
I don't know if you can do this in aopk.
i have a great solution (with a notification-so i will try your suggestion 386 once my rom is done backing up), but want to make my own personalized "build (apps, tweaks etc) thread". Where can I make it without getting slapped by the mods? In the galaxy s3 general thread or since most of it is can be done on different android phones in the the overall general thread?
Hello Everyone,
I have a problem with my amami and I doubt I am the only one but for some reason people do hardly complain: the brightness even at lowest possible setting is still too bright.
I had this back when I had original FW and I am having the same issue with CM11 (latest nightlies). Using manual control or auto-brightness doesn't make much difference, i.e. in a totally dark room the ambient light sensor reports 0Lux and the screen is still too bright.
I found a workaround already (the ScreenFilter app that people recommend all over the internet) but it sucks because it heavily reduces the picture quality, i.e. visibly reduces contrast and especially the gray color resolution. And it also doesn't reduce power consumption like real brightness value change would do.
I looked around for possible solutions and there is a trick with writting a new value of current limit to Linux settings (some mA value between 0 and 20 to some max_current file in procfs). And this really helps but also impacts the maximum brightness, the screen is hardly ready in sun light with reduced current.
Is there a silver bullet? I am thinking about writing an app for that but it would require SU permissions and is kinda dirty to implement. Can anyone recommend a better solution?
have you tried the xposed Modul "minimum brightness" ?
Install Lux Brightness. from play store.
You can overboost it or make the screen so dark that you can't even see it.
Another great screen mod is Twilight which basically dims the screen red based on clock so it helps fall sleep faster when using phone before bed.

Thanks for the hint. I tried the Lite version and AFAICS it simply uses the same trick as ScreenFilter and other "sub-zero" regulators, putting an alpha overlay on top of the image stack.
You can identify this kludge easily by looking at the button areas, they don't get darker anymore. And you can see the black level not getting real black, i.e. the power consumption is not reduced.
However, Lux seems to be one of the better toys because of the plugin interface. Unfortunately there is no HW plugin for Sony devices but judging by the quick look at the Nexus-4 plugin (it's open source!!) it should be possible to adopt this method to Z1 as well. So, maybe when someone could eventually implement that.
xposed Modul "minimum brightness" works, i tested it for you. you can make the screen dim to complete black with your normal display brightness slider without grey or black overlay. it just sets down the minimum brightness level to 1 or 0 (default is 10 or 20), so it should also work with enabled auto brightness

As far as i remember, /proc is only used to call upon information, not to set specific values. What you are looking for is placed within /sys.
To be precise in /sys/devices/leds-qpnp-ee125e00/leds/wled:backlight/. There you will find a file called max_current with which you can easily control the brightness and set it to a very low level. Note that this actually dims the screen and not just applies a filter like most apps do...
One drawback is that the value will change again after you restarted the device. I set up a little flow with Automate β that takes care of this for me. I find this solution a lot better than all the screen filter apps.
This is true for CyanogenMod 11 and GreatDevs Kernel. It might be different on Stock. I know that the path for my Nexus 7 is sys/class/leds/lcd-backlight.
I hope this helps you a little bit.

I am wondering how you can claim that the result is complete black. Calling this black is like saying "TN monitors have good black values" (I know such people, they change their mind quickly when they see my Eizo with a VA panel at night).
No, seriously, the default was already 10 (see config.xml in cm11 repo) and the difference between 1 and 10 is hardly visible. It's still way too bright for work without eye strain in the darkness.
@Wooaarr: thanks, this is apparently the way to go, I just need to find time to configure it. And yes, of course, the file is in sysfs and not procfs (automated typing, when I grew up with Linux there was no sysfs out there ).
