Is it possible to tweak the auto brightness levels now that we have EC10 kernels (someone had told me that auto brightness levels were controlled by kernels)?
It seems like this would be an awesome opportunity for some battery life savings...
Why not just keep it on a low setting, then bump it up whenever you need to?
Just slide your finger along the notification bar or use a widget.
I know I know. I just thought itd be nice to get some use out of the ambient light sensor...
Hi! My question is: Is there a BIG difference between leaving lowest brightness setting and auto-brightness? If so, how much? (Hours, battery usage, etc)
Thanks! I hope this thread will be informative for everyone..
Auto-brightness consumes more battery because it is constantly changing brightness, if you want the best battery power just use the lowest brightness
as aaitken said auto brightness consumes more battery . its better to use low brightness and use a brightness control widget from market and change the brightness manually when required

If you have a stock firmware, or a stock based ROM, you can adjust brightness anywhere you can access the notification bar. This is built into TouchWiz. Just hold your finger on the notification bar until you see the pull-down shade, and slide your finger left or right to adjust brightness.
I leave my brightness on lowest and adjust as necessary with this, i.e. when I'm in a bright setting, and need to turn my brightness up.
Also there is brightness options in AOKP with the toggles and in CM9 (and most other AOSP roms) as a power save widget bala_gamer's option's also a good way
Thank you very much for your helpful answers..
Hello,
I'm one of those first users who has received GS3 in the first days of June and a user of the FoxHound Rom which is very good since doing some undervolting, modifying the kernel and changing some other setting like free ram modem changing I achieved a very very long battery life (at least +50% of battery life) and a butter like transition as screen effects.
The only problem for me, which would be with every GS3, it's the maximum brightness. It's too low. In the FoxHound mod there's the famous STweak which theoretically has a setting to improbe the maximum brightness from 28 (default) to 35... but I don't think that it works.
Do you know some other root app or some kind of mod which allow a really improvement of maximum brightness? Cuz as default, this display is too dark under the sun, which is one of the the two major defects of this smartphone (the other one is the materials... I'm ok with the chassis made of PC but the backcover made of PC too, no. I'd have rather chose some aluminum alloy or mg alloy with MAO treatment.)
Thanks in advance guys.
Auto brightness is profoundly terrible on the S3.

Try Lux Autobrightness in Google Play. It works for me.

Does it increase battery drain?

I guess it will but not much so far.
No guys, wait a moment.
If I'm not wrong, your talking about apps which modify AUTObrightness. But as for that I've already solved just with STweaks which allows to modify autobrightness setting. My concern is for MAXIMUM brightness..Maximum brightness is not modified by autobrightness settings.
As for me lux doesn't change the maximum level.

I`am only interested in the minimum autobrightness values. And this apps solves it for me.
As for minimum value I agree but this doesn't solve at all what I asked in the first post

Uhm ... that's bad ... I mean, what I need is exactely the FoxHound (graphic aosp like, all samsuns built-in apps, downclock and downvolt option on both CPU and GPU, STweaks, kernel like siyah) just with better maximum brightness ... so changing to an aosp rom, I'd prefer to avoid it.
I'm giving a shot to the tone tweak but I don't see any remarkable improvement at the moment...

Where are those modifications to Auto brightness? I don't see anywhere in STweaks where they can be made.
"min_bl" in brightness curve setting.. if you increase it the screen will remain at lower brightness level at higher environment brightness.. practically you change how it reacts to environmental brightness. As for me, it works.
But here you cannot decrease the minimum brightness level.
Any hint?
How can I change the brightness levels on the s3? I would like to have a lower brighter level than the minimum level and be able to lower all with the brightness bar. I tried going into framework-res.apk and lowering some values for auto brightness in array.xml but that didn't work. It just gave me a black screen and sent me to the lock screen whenever I tried to adjust the brightness. I know that there are apps that can lower screen brightness but I would just like to do it with the brightness adjuster and save a little memory. Any help is appreciated. Thanks.
I found an answer to my question. It involves going into service.jar, system.apk, and SystemUI.apk and making some changes. Found the information in this thread

Although, this thread is for the Samsung Galaxy SL, much of the info appears the same for the S3. Will be testing and updating later
Or u can use "Eyesaver" app its wery nice
Hi all,
I frequently use my phone at night in a pitch black room. It is therefore nice to have a very dim screen. The most I can dim it is not enough.
Yes, I know of programs such as ScreenFilter which provide a software overlay of the screen. But, that doesn't help battery life, and the screen is still emitting the same amount of light.
Is there a way to edit some build.prop setting or something to reduce the minimum brightness? I'm on CM10.1 if it matters.
Thank you!
