So I was looking for a way to reduce brightness of the screen as i found it way too bright even at lowest setting and I found this info on SGSII forum so all credit goes to them. I just thought some of you might find it useful. So here it is.

Thanks LockeOn for sharing.
Just a quick how-to for everyone else before more people post on how to apply the MOD, using APK manager (I think this is the easiest method)
Steps
Download APK manager and unpack somewhere
Grab framework-res.apk from your phone under \system\framework\ (e.g. adb pull) and place it in the "place-apk-here-for-modding" folder
Run Script.bat and select option 9
Once done, go to projects\framework-res.apk\res\values\arrays.xml and edit your values as per first post.
Once edited, compile the apk using option 11
Qn: Is this a system apk. Ans: y
Qn: Aside from the signatures, would .... least. Ans: y
Prompt: In the apk manager folder u'll find a keep folder..... done then press enter on this script. Press any key to continue . . . You have to go to "keep" folder and delete resources.arsc because arrays.xml have been changed. After this You can press any key in apk manager window.
Once done, input 22 in apk manager and select "unsignedframework-res.apk" by entering the number that stands for it. After selecting it You should see in apk main window in the top right corner "Current-App: unsignedframework-res.apk". Now press 5 to zipalign apk. You will find your completed, zipaligned apk under place-apk-here-for-modding\unsignedframework-res.apk
rename back to framework-res.apk and adb push the file back to your phone.
And here are the values I use, taking some values from my Hero days
Code:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>5</item>
<item>25</item>
<item>60</item>
<item>125</item>
<item>255</item>
</integer-array>
Since some MOD (like APM for example) make changes to the framework-res.apk, it is better for you to do your own instead of begging others to do and post here.
Edit1: Updated steps as recommended by LockeOn
Edit2: using more aggressive values now after few days testing
Code:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>2</item>
<item>15</item>
<item>32</item>
<item>100</item>
<item>200</item>
</integer-array>
before this, i was always using minimum brightness instead of auto brightness thus decided to set 32 and below for majority of the values. it works for me when i am indoor and outdoor under low light. when outdoors under brightness, the increase is bright enough for me so I believe i have found my sweet spot
note that my environment and preference may diff from everyone so what works for me may not work for you

Couple of steps that I did that are different are that I used root explorer to transfer files from and back to the phone. While you are doing this you can also edit the crt animation like i did. I'll attach my apk file and you could use it if you use stock rom I believe.
You are doing this on your own and keep that in mind.
Also note that this is going to reset your wallpaper and your gmail account(meaning you have to sign in again).
What's all the hubub about? Have you tried this, https://play.google.com/store/apps/...2ZWZpc2gud2lkZ2V0cy5icmlnaHRuZXNzbGV2ZWwiXQ.?
The difference between the app and this mod is the minimum brightness. With this mod you can go beyond minimum that is set by samsung. For example, minimum for stock has value of 32 and one that I edited is 2. Plus you can add crt effect when turning off screen.
edit: I forgot to add that if you are not using automatic brightness you can simply slide your finger over the notification bar to achieve the same results as the app is offering.

Well, with settings change that I did I get almost identical auto-brightness behavior as with galaxy nexus. I quite like it.
works great! thank you
The lowest setting is "way to bright "? Seriously?
I have mine set on half to bring out the beauty of the screen

ok? if you like somebody's work hit thanks, if not just don't comment at all. the screen dim you are talking about does not lower the brightness levels, it just dims the screen meaning your battery life doesnt improve. while this mod actually does REALLY lower your brightness=>better battery life as well!
this isnt to far off topic but is there any way to adjust the brightness of the touch buttons at the bottom of the phone....it seems like you should also have an adjustment on how bright or dim those buttons illuminate

I just turned mine off. I know where each of the buttons is, and unless im in the dark, i can see them anyways. No need to have them illuminated in my opinion.

it actually is easier than flashing a zip file. all you gotta do it use some kind of root explorer apk and copy paste the file. as it regards most apps in the market, I have the feeling they just put a tint on top of the screen and make it look less bright
Where do u place the file? I have root explorer and know how to use it.

After downloading the apk file, it doesn't show up on in to-be-installed options list on the Apk Manager app.

I was wondering if someone could create (or if there already is) an app that will dim the screen a lot more than just setting it to 0. I work late hours and come home, just wanting to unwind and play some solitaire. I'm blinded by the screen. I know that there are night/clock apps that can do this. Thanks!
I second this request. The screen is quite blinding in a dark room. A night mode would be nice too have.

I would pay for this app, blows my mind how they could make a phone that can't dim lower. Even when setting brightness to 10 with Dimmer it's a real pain using this phone in the dark.

Why not just slide your finger across the task bar from right to left and it would lower the brightness to the lowest setting. To brighten go the other way.
Way easier than another app.

Thanks, but not what I was talking about. I'm talking about lowering the brightness past that for nighttime usage. I know it's possible; I have a bedside app that lowers it way past the default.
BTW, that trick only works with Auto Brightness off.
yeah this would be nice. also, having those cool filters like on CM6 would be nice too. the red filter is great for checking your phone in a dark movie theater.
OK been using adj brightness in the market and it was brilliant in brightness control. Unfortunately it doesn't work on the galaxy s2 and because my eyes play up, am finding the phone to bright for me especially when using it at night when lights are off, what alternatives are their to lower the brightness level please.?
For Amoled screens of any type "Screen Filter" seems to be the best.
I agree. Screen Filter seems to be excellent and can make the screen as dark as you ever want. (to a level that no LCD can ever go to imo)
Thanks guys it worked it is the best av seen so far.
I got mine sgs2 on Saturday and hadn't really thougth I would need an App to control this, the settings ont he power widget were good enough for me. However, I tried this out for a laugh and it works well. Will definitely use it at night time.
Although at the moment I am just enjoying the super brightness
Birghtness control from the notification bar
Can one still adjust the brightness by swiping the finger along the notification bar, like one did on the i9000?
Can one disable the automatic brightness from somewhere in the settings menu on the i9100 in the same way as the i9000?
Yep, same thing works in the SGSII.

Hi Crypticc,
You misunderstood what I wrote.
1) I referred to a partially completed sentence:
" How I just tried dropped down and not" - not what?
2) You have confused the verb 'to swipe' with an application called Swype.
As I noted, you wrote your location was from London, yet that you are not a native anglophone; No problem, but I was a little confused in the beginning.
To summarize: Your reply confused me. You partially clarified what you wrote, and now I understand. Thank-you.
* Back on topic
In order to change the brightness by swiping along the notification bar, please ensure that you have turned off the automatic brightness adjustment setting in the menu. I do not recall the exact name. Then, it should work.
I think that this can be found in : Settings -> Display -> Brightness
Best regards.

Sent from my SAMSUNG-SGH-I717
I believe you have to use apps found on the Android market. That was also the problem I found with this phone. I'm used to Samsung phones allowing you to maker the screens dim extremely dark right out the box. The Note is my first Samsung phone, and it really doesn't have that many brightness settings. The lowest setting is still fairly bright. I downloaded an app called Lux from the market, and it's amazing. I can make my phones screen almost pitch black at the lowest setting.
Nice thanks I just got lux and it better than the screen filter

Be carefull i used one that dims it to 0
and i did that accidentally and it stays in the settings after a reboot , i had to blindly find the app on homescreen and luckily got the dimmer to 15% brought the daylight back

The app called Dimmer will take you from 10 to 0 (10 is as low as you can go with the stock brightness control). However, I later found an app called Screen Filter which works even better - you can make the screen even darker, I found 0 to still be very bright in a dark room.
Even better, you can set up Screen Filter so it dims the screen a small amount all the time to save some battery life.

I really didn't like screen filter as it ruins the clarity when you dim... I used it on my evo and it was good while it lasted, but as Dr. Evo directed me to lux, it's a great app as it actually dims the brightness, and doesn't distort the screen with a filter

You're right. Lux is pretty cool. And it does go lower than the app I posted. Thanks. I'm trying it out.
I was messing around with the settings on my phone to try and eek out some more battery life. I noticed with the stock battery monitor that the screen was using the most battery (as is expected) so I turned the brightness setting all the way down using the slidebar in settings.
Then I went into the Sprint Zone app, clicked help, then my device, then power controls. There it shows what is turned on on the phone and a general breakdown of how much those things are drawing on the battery (kinda nifty). On the lowest possible brightness setting it says it's at 11% and that that's "medium" usage. Is there a way to get screen Brightness lower? I just find it odd that it still registers as medium usage on its lowest setting...
Also has anyone noticed that on the "Automatic" screen brightness setting that the screen doesn't go as dark as it could go when there is a low light condition? For example if I'm sitting in the dark with auto brightness on, I can turn it off then make the screen darker manually than it would go on auto.
Any thoughts? Or fixes?

Try rootdim. Also, the screen brightness is going to be mostly controlled by the kernel, so try using a different kernel or build one from source.

It's not in the kernel, it's in an xml or something. There are seven brightness levels (I think it's seven) based on lumens, and there's an associated screen brightness value assigned to each on a scale of 0 to 255. Stock auto brightness levels set the bottom three levels to the same brigness value. I think it's 63. Setting the brightness manually, you can go as low as single digits, maybe even zero.

That's cool you can edit the XML files, but how can screen luminosity or display not be part of the kernel or kernel modules? I have an HD2 with CM7 on it, and through installing different kernels and whatnot, I can get different features for display like render effect, auto brightness, and whatnot. Is this only just for sense ROMs then?

So maybe the stock rom doesn't let you zero it out? It's posting the lowest value as 11% as read by the Sprint Zone app. Maybe they do it as a safeguard against setting it too low and not being able to see the screen to turn it up when it gets in a brighter environment?
That's a funny thought, I could see me kicking myself over something like that. Would be nice if we could make that call on our own though, wonder how dim it is...and why not make the auto brightness go to the lowest setting (or perhaps even lower than the stock setting)? At least then it would ramp back up as needed.

Did you try rootdim? I'm pretty sure you can dim the screen lower than stock with it on this phone. I've only used it on my HD2, but it worked well with it and It's free.
Nm rootdim only allows the screen to go down to a value of 30. You can set lower values, but it doesn't change the brightness.

Correct - stock only lets the brightness go down to 11%. I'm not sure if auto brightness will ever set it that low though, doesn't seem like it does.

Yea that's what I'm saying it doesn't go to the minimum. I mean I'm sure the battery savings isn't much, but another usefulness of it going that dark is when you check your phone at night in the car you don't want the phone to be all lit up inviting attention.

I think 11% is probably dim enough for most cases. If you have a dark background that will help with the car situation. The only time I find it still too bright is when I'm laying in bed at night. I haven't rooted yet so I can't comment on the solutions others suggested but give that a try. You probably won't save that much battery though unless you're in the dark a lot.

Sorry, I gave too few info: I wonna stay on TW-base and there's only the slider, which doesn't make lower brightness than 20 (with the edits, I mentioned).
CM-, AOKP-roms offer manual adjustment and with that I got lower brightness.
I use this app when I'm reading something at night:
https://play.google.com/store/apps/details?id=pt.bbarao.nightmode
You may invert color to turn whites into black and reduce screen consumption, w/o installing or tweaking anything
I use black themes and I can adjust brightness lower than 20 by an app. My question is&was: how can I simply adjust it by system-value?
