Hello all,
I've been poking and prodding my new USA GSM Galaxy Nexus all day and I noticed something: the screen seems to have a dynamic contrast function, similar to that of new TVs. I would like to turn this function off, although I don't see anything in the stock ROM to do this.
NOTE: I AM NOT TALKING ABOUT "AUTOMATIC BRIGHTNESS".
I want to see if anyone else can reproduce this or if it's just me.
Turn off "Automatic brightness"
Set your phone to 100% brightness.
Hold your Galaxy Nexus in portrait mode.
Go to this page in your browser on your Galaxy Nexus:
http://www.samsung.com/us/
(make sure to request the desktop site and not the mobile site in your browser of choice)
Scroll down to the bottom of the page and zoom into the black section with all the links. Zoom in as far as you can. If you're using Chrome, the words "Who We Are" should go across the length of your screen.
Scroll your screen so the words "Who We Are" is at the top of the screen and no white background is present at the top of the screen. The lettering should be pure white. Remember where they are.
Slowly scroll the page up by swiping your finger down the screen so that you gradually see more of the white background and less of the black background until the black background completely disappears off the bottom of the screen.
Swipe back up so that the words "Who We Are" are in the same vertical position they were in Step 6.
Repeat steps 6-8 multiple times at a faster rate. As you keep scrolling, watch the brightness of the screen and/or the whiteness of the words "Who We Are". When you first start to see white, the white will be white, but when more white starts to take over the screen, the phone switches to a less-intense white. (I'm assuming to save battery)
Is anyone else experiencing this?
download supercurio's voodoo mod sequel, the displayexpert beta in the voodomods forum. there is an option to turn off the dynamic brightness limiter. works perfectly!
This comes up once in a while, and many people say they see this issue. But I just can't see it! The sgs2 has the option to turn this off, but nexus doesn't.
Is this available in the kernel code to view and tweak,or is it closed?

Are you considering adding this into AOSP and letting Google know, or just tweaking/adding to other custom ROMs? Or just curious?

I'm not really a dev in any sense, but would like to see if this function is in the kernel and not hidden. If its not hidden then I'd imagine someone would have added an on/off option by now. So I'm not the person to handle this. My ability is at most compiling my own kernel with a little code change, at most, unfortunately.
Yeah. There is some kind of brightness limiter like plasmas have it too to meet energy star standards. Its a lot less noticeable on a phone screen and probably helps with power management. It can be a bummer on plasma watching hockey or movies like ice age. I would gather there is a way to tweak it. On plasma, no go.
teach a man to fish, you feed him for life. teach a man to fastboot, and you create competency. and less threads on xda.

all plasmas can turn off dynamic whatever. i am referring to what is called auto brightness limiter aka ABL. i know samsung and panasonic utilize it in their plasmas. no way to tweak it. there is something similar with samsung phones with amoled. bright images get toned down because all the white/brightness suck a lot of juice. i don't know if it can be tweaked on phones, but i think it can somehow.

I need instructions on how to do this on an unrooted Galaxy nexus GSM..step by step..Thank YOU!
SONY XPERIA S's Auto Brightness is always on, so there's no need for some application to do that for you.
TEST : Press your DIAL icon and type this code : *#*#7378423#*#* : Press Service tests : Scroll down to : Ambient Light Sensor : Press it and you should see some values. Now put your finger on the sensor and those values will change. Now you know the sensor is working OK.
The build in Brightness which is in Settings/Display should be set over/or to 60%, if it is set under that value the auto brightness will not be ''AUTO''
And of course you can do a test in broad daylight, when the sun is up
Put your finger on the sensor and see the step by step brightness difference/changing.
Unrelated-hint : If you want to enter another secret menu this is the code : *#*#4636#*#*
You'll see :

Well the point for this is that I saw so many threads about Auto Brightness apps, modes, tweaks and some other stuff, that are irrelevant when you know that the Auto Brightness is ON and ALWAYS working. The Auto Brightness is ON, so there is no need for some application occupying space on the phone, to do what your phone already is doing by itself.
And you're right, that's not a secret menu, but it's not a sub/menu in Settings either

The proof is in my first post. But more easy, go out in the sun, put your finger on the sensor and the brightness will decrease automatically and vice versa.

He is right, but auto brightness works with 30% and up of a brightness.
Sent from my LT26i using xda app-developers app
The best value is 60 %. Any value under that will not make much difference regarding Auto Brightness.
I keep my phone on 30-40% and i can clearly see that auto brightness works and makes huge diference.
Also IMO 60% is to hell bright, and i can bet you barrelly can use display more then 2:30-3:00 hours.

Keeping the level at 60 %, which is the default setting will not drain the battery that fast. Under that, as you stated that you are keeping it at 30 %, well, in a few years you will need glasses. It's a smartphone,with HD screen resolution, let it do his job, make the best of it. Normal level is 60 %, not 100 % but for sure not 30 %

Can you cite any scientific data to support your claim of loss of vision due to chronic use of low backlight screens or are you repeating a myth that our grandparents told us when we tried to read a book in darker rooms? All you can get from extreme cases is temporary eye muscle fatigue, nothing more.
http://science.howstuffworks.com/life/human-biology/reading-in-dim-light.htm
Another thing, I have done some endurance tests concerning impact of backlight on battery life and between 30% and 60% there is a substantial difference (few hours) in battery life.
Temporary eye muscle fatigue it's already SOMETHING you can GET from low light reading,right? But anyway,the truth is always somewhere in the middle. The point is that there is no need for an application to handle the Auto Brightness.
THERE IS A TRUTH IN EVERY MYTH!!!

This thread is about Auto Brightness. I will ignore all off-topic comments.
I'm listening to your comments, and I put my brightness on 60%.
I know that the auto brightness is working, I've tested it many times. The best test to see something is to put the phone under a light bulb. You'll see the screen going brighter.
I'm curious why to put on 60%, I always have my phone on low brightness. When it's sunny, it brightens up itself.
Cheers
Give it a try, 60 % it's the default brightness on SONY XPERIA S. The phone's battery will not drain,and you'll see better what's happening on your smartphone screen
Best of luck.

Set it how you want it, this 60% perfect and non battery draining setting is bulls*it. It's just an original preset, that doesn't mean anything
Logic tells the less % the less battery drain.

I love this tablet! It's super fast, the battery life is great, and the s-pen features solidifies it in keeping it a next gen iPad killer! But I have one question. Is it me, or does it seem like the auto brightness is a little too dim for the screen most of the time? I find myself when playing games (mostly dark ones like Need for Speed Most Wanted) that I have to turn the auto brightness off and manually adjust it in order to see and keep up with the fast paced action that's going on. I also find myself doing this for movies as well & I wanted to see if any of you guys had similar issues.
PS, it works great when I'm in a bright area, as the auto adjust does its job correctly and crank the screen up, but I'm rarely outside with the tablet. It just seems like when I'm inside of a building the screen is entirely too dim
Thx,
Eddie

turn off the auto brightness and put it at 40%. Will be perfect. Auto brightness has issues.
Screen Dimmer
The minimum screen brightness is too damn bright to use in the dark.
Run the app, click "Load" next to "n5dim", change your brightness to the minimum (and then up a bit and back down) and notice how much dimmer it is.
The brightness at all other levels stay the same.
Source: https://github.com/mzhou/n5dim
Fast Charge
This works by setting the registers on the bq24192 charger chip to allow as much input current (from USB/AC) as possible, as well as allowing as high a charge current as possible (to the battery).
From limited tests I've performed in the past, this actually isn't enough to get faster charging, so further investigation will be needed, though your testing will be much appreciated.
It will take effect on the first time you plug in after clicking "Load". If you're already plugged in, you need to unplug and replug for it to take effect.
Source: https://github.com/mzhou/n5charge
General
To use either of these, you need any kernel which supports modules (CONFIG_MODULES=y).
I've attached (modules_boot.img) a stock kernel with the config changed to support modules.
modules_441_boot.img is for 4.4.1, while modules_boot.img is for 4.4.0.
Does this dim further than setting '1' in /sys/devices/mdp.0/qcom,mdss_fb_primary.160/leds/lcd-backlight?
(Also I noticed your CSE email, a fellow UNSW student?)

Yes. Dragging the brightness slider to the minimum already sets 1 there.
There's values hard coded in the platform data to internally restrict the value to a minimum of 5 (but that's of little consequence).
The main gain is is from the "full scale current" (you can find an explanation in the datasheet for lm3630) which has been hard coded to 18 in the platform data. Bringing it down to 0 makes a huge difference.
(sup)
Nice work! I wonder why they limited it. Possibly to stop people putting their phone into an unusable state during the day?

No app will be able to get the backlight this dark.
I'm not sure what Lux does, but if it modifies the colours to produce a darkening effect, then the contrast will be very bad.

Hey there, I'm actually the developer of Lux. The main purpose of Lux is to replace your auto brightness system without the need for root access. That being said, there's no reason why this neat kernel module couldn't be added to a root plugin for Lux.

Ah cool.
I tried out Lux and I'm not sure if it's a limitation in the free version, but it only sets the backlight brightness (/sys/class/leds/lcd-backlight/brightness) to a minimum of 10 before it starts doing colour adjustment instead.
My module treats the value 1 as special for making the backlight super dark. Dragging Android's built in brightness slider uses the full range of values 1-225 inclusive.
There's no reason it couldn't just map the full 1-255 to a wider range, but I initially wanted to lean towards keeping things as stock as possible.

It does that because some devices do silly things near 0 like putting the device to sleep. You can change the minimum brightness in settings to 1 which should fix this (although I suspect it might round 0.01*255 to 2. I'll have to check my codebase).

Somehow overlooked that when I was skimming the settings. (And it does round to 2 ).
I could make 2 or anything less than 5 special so that Lux users can benefit. Or maybe just make it configurable with a parameter at insmod time...

Whatever you feel works best. A parameter sounds like the most flexible solution though.
This is exactly what I was looking for!

Flash the kernel in whatever normal way you choose.
Extract and copy n5din.ko to your phone.
Use root and put it in /data so that apps with SD card access can't mess with it.
Run "insmod /data/n5dim.ko" on your phone. This can be with a terminal emulator or adb or script manager.
I'm probably gonna be making more modules so I might make an app to simplify the process.

This is really dim! I'm impressed. If you ever decide to modify it like you mentioned earlier so that the full brightness adjustment was available I'd be interested. It would be useful to have access to all the brightness levels between yours and the ordinary minimum brightness.

Not so sure you have a hardware problem as both the stock autobrightness and Lux Lite use the same sensor to determining when the brightness requires adjustments. So I'm not sure what's going on. Well at least you have an alternative while you figure out what is really going on.

The auto brightness on the S tabs is useless. I think what happened is that they simply used the algorithm for brightness adjustment from the Galaxy phones but didn't adjust them to compensate for how dim the AMOLED panels on these new tablets go in comparison. Lux's adjustment actually works and I really like the app because it's one of the few that finally show you the actual brightness percentage.

After trying the free version I purchased the pro version. What I found is that I used two different profiles, the regular "Auto" (Day/Night) for indoors and "Cinema" for outdoors who's brightness is always higher the indoors. Swapping profiles is very easy. I even have a one brightness setting profile for watching videos with the lights off at night. So the pro version has been well worth it.

You are correct. That's how all of my Samsung devices work when enabled.
My auto brightness didn't even do anything. Didn't works since day one. When I turn it on.... it goes almost completely dark. It sucks.
I want to exchange it. But since I have 30 days with Amazon... I'm hoping the 32Ghz comes before I swap it.
Sm-t705, sm-t700
On the sm-t700 (WiFi) autobrightness works much better than on the sm-t705 (LTE-Version). I checked the hardware with CPU-Z and HW-Info apps.
The light sensor (type CM3323, Capella Microsystems) of the SM-t700 is rated max. 3000 Lux and the sensor of the t705 is rated up to 65000 Lux (type TMD3782 from AMS). I guess the algorithm or parameter settings are the same for both devices.... this might be why the prob is even worse on the 705.
!!! So if you respond to this thread always tell us which device you have !!!
- I am wondering if there is some kind of parameter file where the margins ... can be set (of course this would require root) ?
- I am anxious that an app like LUX would drain the battery more than the built in app ... what do you think ... ???

Drivers I'm sure are complied with kernel and parameters should be in source. Maybe also modification to ROM framework-res would also be needed. Remind me in a couple weeks time after I've updated the 8.4" kernel and released the 10.5" kernel. Maybe I'll have time to at least take a look.
Works just fine for mine.
