Hello, I'm looking for a way to reduce the screen brightness even more than currently possible. It is too bright for me to read at night at the moment.
Is there some way?
Check the market. There are way too many apps out there to do the task you wanted.
via xda app
I already have but none of the applications on the market allow me to make the screen really dark. It's still pretty bright even after using programs like AdjBrightness or ScreenDim.
I'm curently using Screen Filter but that only puts a grey overlay over the Displayed Applications.
Try this one: https://market.android.com/details?id=mobi.pruss.superdim
I haven't tested it though.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Already tried that, it is no darker than the lowest setting from the built in menu. Other Android devices can go much darker. I was hoping, that it is just a kernel issue or something like this.
How is it that sreec filter doesn't do exactly what you want? It gets very dark, doesn't it?
One other possibility would be to use Cyanogenmod or any other Rom that lets you set the light sensor levels manually. In my experience, this feature seems to save lots of energy. IF you manually set those levels to very dark, you may get what you are looking for ...

Hi guys,
i did a search but have found nothing regarding this kind of problem.
My display shows some kind of pattern on plain colors.
http://dl.dropbox.com/u/16054199/screen.jpg
Its worst on grey and white, (certainly) not seen on a black screen, and its almost not visible on the highest screen brightness. But, its very distracting on everything below and also visible in pictures etc. if looked closely.
I come from a S2 which had not this effect. Is it a faulty screen or a normal effect of the pen tile matrix?
I see the same thing when my screen dims down before it goes to sleep.

Just before it goes into sleep mode? (which afaik is even darker than the darkest setting while it`s awake).
I clearly see it under medium backlight setting, the grey elements of the market are a place where i always see it.
hate to break it to you, but that's just how the screen is(especially when the brightness is turned down & on plain colors). i've had 2 Nexus' and both did the same, even the ones on display in my local verizon store are the same way.
Turn the brightness up and it will go away. It's a quirk of the screen technology.
Allright, so i have to live with that... Thanks for your answers!
Is it possible to edit the levels of the automatic screen brightness?

If you're rooted and have Clockworkmod you can use this:
http://forum.xda-developers.com/showthread.php?t=1377410
Just make sure you meet the requirements and follow the directions in the thread. I have used this on a Verizon LTE Galaxy Nexus and didn't have any issues, even though it is in the CDMA form.
I am not the dev of this mod, just passing along the info.
awesome, thanks a lot!
I wonder if there's some kind of deeper hidden meaning to the pattern, some kind of subliminal message jk
Terminators run on Android...
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.

Anyone getting error when trying to install?
Specifically "Error processing purchase..."
Sent from my SGH-I747 using xda premium
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.
First things first, i want to APOLOGIZE if this is a repost as i haven't been able to find this issue else where unless im just that blind.

9-20120724 nightly.
When brightness is set to max, and auto brightness is turned off the following happends.
Overall brightness seems a little dimm, not a whole lot but enough to notice, however when i slide the notification slider down the bottom of the screen gets brighter, also when in email or messaging app, when the keyboard is open the top half of the screen become brighter, were talking about about 10-15%
Is there a setting i can modify in a file that represents the overall total allowable brightness, i just figure if the screen becomes brighter under certan circumstances then it might be possible?
Also the color almost seems a little be off, like white is not quite white. Annoying for extended reading sessions.
tried changing the mDNIe settings but nothing changes.

Really? Mine does the same thing. I figured it was the ROM cause stock I haven't noticed it. My HD2 did it as well. I honestly think it has something to do with battery saving. I noticed if there is a lot of white showing it dims it a little, then when there is a dark image, it increases the brightness.

can somebody share their CM10 setting for the display light control please.
i find that is it to bright when in a dark room,what setting should i change to lower the screen auto brightness ?
thanx
I am also interested as I would like to decrease the screen's battery usage.
every setting will be personal, as testing conditions and displays always differ. experiment yourself, dont go over the stock limits and if you don't like your experiment's result, reset to default and start over.
search about gamma color control to know what it does.
and there's a sticky on a colorabotive effort to find the best setting in general subforum, i think. no need to start a new thread over this.

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.

Yes, another vote for Lux. It lets you set brightness to negative levels, mine is usually around -50%. https://play.google.com/store/apps/details?id=com.vito.lux&hl=en

Nothing comes close

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 ).

Interesting information, I did not know that. You are correct, the navigation buttons are brighter than the rest of the screen at negative values. I had noticed that before but didn't know why. Works well enough for me though.
