I was trying to lower the brightness very low to test how it would affect battery drain and it seems that the phone won't let 3rd party apps lower the brightness lower than what you can set it to, in the phone's settings. I tried an app called timerrific that lets you schedule various settings changes, but the phone seems to be overriding it. When I set the brightness to go down to 15% via the app, it does go very dim, but then immediately bounces back up to lowest level the phone's settings let's you set it at. Also, I had auto brightness off and the power saving mode off.
Has anyone been able to get the phone to go to very low brightness?
Thats a good question and would like the answer too... to me, the lowest brightness which must still HOG the battery as sometimes it seems to drain very fast with usage (and I have it on the lowest setting)... seems overly bright. I would without a doubt use it at a lower brightness to conserve energy depending on what I was doing at the time.

Not sure what you mean? For example, if I set the brightness to go down to 5% through the app Timeriffic, the screen will dim down to where I can barely see anything, but then it immediately raises back up to the lowest setting you can set in the phone's normal settings, which seems to me to be about 25-30%.
Yep

This is actually correct, the screen is what makes the "Automatic" brightness setting on the SGS phones look brighter than their LCD brethren. As we all know, currently all AMOLED displays use some kind of Pentile Matrix. All HTC devices (The N1 included) currently use RG:BG Pentile Matrix.
Do a google search on: "RGBG Pentile" and Samsung's site details it.
The SAMOLED display Samsung has made uses a new Pentile Matrix called RGBW:
Do a google search on: "nouvoyance" and it's the first site (sorry for the odd instructions, won't let new users post links )
Using the new RGBW, a white subpixel is introduced on top of the standard RGB stripe. From my reading, this allows the screen to achieve the same resolution to the eye with 33% less subpixels and is a brighter display in the process.

Good explanation, but are saying that no you can't dim it to low levels because it makes it look brighter than it is? If so, I don't buy it. I see it being dimmed to a low level. It just doesn't stay there.
Aldiko reader can get the screen even more dim

Also since there is less air gap in the new display, it is brighter.

This is just me speculating, but I'm thinking maybe the brightness setting is universal to android devices, except that it's calibrated to normal lcd. So the same voltage(or however they regulate the display brightness) on an LCD will look brighter on the Super AMOLED. For me, the dim setting on the auto-brightness seems too bright.
One thing I've noticed is I can take the brightness down to its lowest setting and it still seems bright..however on almost every phone I've used its like this.
The weird thing is on the Captivate I can open the browser, men then scroll down to settings and it has a brightness toggle there that takes it lower.

Yeah that does take it down lower than the home screen by a small amount. I put the browser brightness on the lowest setting and the global brightness on the lowest. Both auto brightness and power save are off. When I switch from the browser to the home screen, it brightens up a touch. So, it does go lower, but not all that much though, and it's only for the browser.

You can totally dim it more. In doing so, it will use even less power than an LCD screen at the same brightness setting.

Yeah, that's what I thought was cool about this type of screen, but I still don't know how to to dim it below the the lowest setting in the phone's control panel (which isn't very low). 3rd party apps I've tried don't really work, or they work, but the phone immediately raises it back up. Are you saying you've dimmed it down to where you can barley see the screen, like 5-10 percent? That's what I'm looking for confirmation on. If so, what app did you use?

I have used this app and seems to be pretty good, makes the brightness lower than system brightness.

i use brightness level too but the brightness goes back to the highest level when you plug the phone in and you cant use the presets on the widget anymore

I tried this app, and while it's a good app, it still doesn't make the screen go super dim. It looks to me like the lowest level (0%) is the same as lowest setting from the control panel. Zero percent should really be totally black.
Screen Filter
Here is your 100% working solution.
It doesn't work with the bright level, it applies a shade/filter to the screen. No matter what app you're using.
Set the bright to the lowest with your default system settings, because if you use a third party that goes below normal, with some apps like explorer, it set it to minimum allowed be system or whatever you set and then you will notice a setp up, shaded but a change.
I'm using it weeks ago and I found it's the best choice to suft the web at night. Also you can turn off softkeys lights

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.

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..
So, we all know that at the moment one of the main things that kills the battery life is the screen.
I don't know how you feel about it but I think the Z1 is really bright, even when at minimum. If we could lower the brightness beyond the normal controls wouldn't that help with the battery life?

Seconding the Lux Lite vote: https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite
With it set to Dynamic and Day, in profile editor change:
Lux - 0 = -55
Luma - 1 = -55
and leave all other variables the same.
That seems to give me a good range of brightness for my eyes - readable in bed with no lights on in the room without waking my partner and full brightness in head on daylight.

It's physically impossible to reduce the brightness at a Lux of zero beyond what the panel/kernel allow. However you CAN apply a dark filter over the entire screen to simulate the effect of reducing the brightness. This appears to be what Lux Lite and Velis Autobrightness both do.
It works fine for me and when viewing the screen in the dark there is very little light emitted using the settings I stated above. However if you don't make the changes I stated above you won't see the darkening effect.

That's a shame. :\ When my phone is docked it shows a full screen
clock: black background, dark gray digits so any screen filter would
just decrease contrast. I guess I'll need to fix a dark plastic sheet to
the dock to physically cut down the brightness.
I ended up putting a microfiber screen cleaning cloth over the device. It's wrinkle resistant
and big enough so it covers both the front and the back without slipping off. It doesn't look
like it but when near the screen it let's through a surprising amount of light making the
fullscreen clock easily readable. Compatible with all Android versions and doesn't require
rooting.
May I ask, it is possible to dim the three buttons below with Lux?

If u have root
I have created a script to lower my brightness below the actual amount, i didnt use any app from playstore as it actually just placed a black overlay on the screen and the brightness was actually still the same
Well go to my Contributions in my signature and under scripts look at the brightness Adjuster script
Try it
Do not set too low value

Hey everyone,
I would like to present you app that I created to automatically adjust screen brightness. Tested on LG K8, Android 6.0. App is using front camera to determine lighting in smartphone environment. I created it because I recently changed my phone and as it turned out this one does not have light sensor, and that was cumbersome for me (day or so after using phone I faced situation when I was outside, it was very sunny and brightness was set to like 10%. It was impossible to unlock phone because I couldn't see anything on screen even if I tried to cover phone screen from that light, so phone was totally unusable!). I didn't find this kind of app on Google Play so that's why we have this thread.
FEATURES:
- automatically adjusts screen brightness
- automatically turn on device boot
- 5 frequency options
HOW TO USE:
1. Download.
1.1. [6.0+] Give permissions.
2. Choose one of available options (I recommend using medium refresh rate).
MORE INFORMATIONS:
Of course app will be improved. I want to add notification with brightness adjust bar, and improve algorithm that is determining what brightness level will be set.

Great idea... However on my k8 its a bit confused... i tried it in the office during daylight, it was quite dark instead of bright and when i covered the front camera its become bright... maybe you could put some options there to manually adjust intesity levels related to the picture brightness?
Good idea

Hey guys,
Is it just me or the minimum brightness level on OP6 its too bright for the eyes?
I use night mode ofcourse, but still... I would prefer to reduce the brightness a little more. I'm rooted, do I have any good options?
I use auto brightness, but also find it a little bit too bright. I don't have root access, so I just use a screen filter app (https://play.google.com/store/apps/details?id=nu.lower.brightness) to reduce it to 60%. It also helps for the battery life
I have the opposite problem, I find the minimum brightness far too dark. There should be a setting to raise / lower minimum brightness to suit individual needs.
