Has anyone else noticed their D3 on stock ROM min brightness is 11%? I noticed since getting my D3 that it has always been pretty bright, even at min brightness level. And using the brightness toggle from Beautiful Widgets, I saw that the two options were 11% and 100%. Is this just the widget, or is the stock ROM set up to keep brightness at this minimum level?
I use my phone in the dark a lot and it kills my eyes to look at it for too long, so I'm wondering if anyone knows how to get the brightness down any lower without switching to a custom ROM. I am rooted, of course.
Thanks for any ideas/solutions.

Brightness Widget Backlight, in the market should work. It's has configurable steps that can go down to 1%. I'm using it on CM7 and can get it lower than the lowest brightness setting.
You can lower it with Quick Settings, but a reboot changes it back. The lower brightness appears to be used when the display dims from inactivity. If you are already on the lowest factory brightness setting it can still dim some more. Thats the only purpose I see of it.
I use Brightness Level from the market and it allows you to go lower than stock does. I believe that it keeps settings after reboot as well.
Sweet, awesome replies.
Lookup screen filter, and should be on the market if I remember correctly.

I just installed and tried Brightness Level and it doesn't allow brightness levels to go below the lowest stock level. I see no purpose to that widget since the Power Widget for android allows brightness level adjustment.
I'd love something that allows for true adjustment from 1% to 100% on the stock ROM.

Screen filter rocks - been using it since I got my D3 back in November.
THE PROBLEM
To save battery while playing video Tegra intelligently decreases the backlight while increasing color brightness and contrast. Because it monitors on a frame by frame basis the changes are often unnoticable. You basically end up with the same displayed image using less backlight.
Unfortunately it seems to get stuck even after you leave the video and the changes are very noticeable as the changes were specific to the video frame you just left and not your homescreen.
This also may be the cause of some ghosting issues and for some it seems to eliminate any ghosting problems for them.
MANUAL FIX
(will reset at each reboot)
In terminal -
(You may need to type "su" and press enter before entering these commands)
To turn it off
echo "0" > /sys/devices/tegradc.0/smartdimmer/enable
To change how aggressive it is (untested)
echo "#" > /sys/devices/tegradc.0/smartdimmer/aggressiveness
Note: battery life while watching videos WILL decrease if you turn it off or decrease the aggresiveness
AUTOMATIC FIX
Trickster Mod
- has the ability to disable PRISM and set it to disable on boot.
N7scripts.rar
- A collection of scripts compiled by hamdir which, in conjunction with Script Manager (available in the market) will allow you to toggle smartdimmer/PRISM on and off at will.
- You can also use script manager to toggle it at boot if you want.
- Also includes a script to disable 3D scaling which may improve 3D gaming performance (untested)
Thanks to hamdir for his pack of scripts and for convincing me to make a new post for these fixes.
I may use this for other sysfs tweaks... mine for now.
Thanks. Easier to save and flash then manually entering in these values each time I crackflash.
If the T3 can increase the color saturation and gamma while decreasing backlight, wonder if we can increase the colors while leaving the backlight alone. All of the N7s I've played with have a dull washed out look with a warm tone for whites.

does flashing the .zip just delete the PRISM file? cuz when I manually enter the command after flashing it via CWM it doesn't allow me to any more.

How do you set up the script? I have script manager and the Scrip.rar saved onto my SD card. Thanks in advance!

Messing with the kernel I haven't had any luck. You could ask Morfic. He might be able to make something happen.
Also prism increase color BRIGHTNESS for the most part (you said saturation). That's why the homescreen ends up looking washed out and bright and not oversaturated when PRISM fails to shut off.

There's no prism file. These tweaks are changing a sysfs value. There's no file. The flashable zip adds an init.d file that runs the manual command at every boot.
In your case CWM is complaining about a file that flashes stock recovery on boot and overwrites CWM. These are completely different things. Let CWM "disable recovery flash" and you'll be good to go.

This is awesome. It definitely needs to be implemented in a ton of ROMs
so does flashing this decrease battery life when watching videos? im confused by op..
awesome post, thx!
yes this fix, completely get rid of the grey levels washout issues!!! and greatly improves the quality of the display, it will cost some battery life, but any boost to this average screen is welcome
now about ghosting it did reduce it a lot but sadly it didn't kill it, i still get the very random occasion of faint LCD ghosting
finally we really need to find out a way to fix the stupid low saturation, in particularly the greens are very low
google....these screen issues, lack of tablet UI and launcher rotation issues, makes want to smash it through the wall
Nice find. Hopefully Google/Nvidia/Asus will fix this in an update.
Thank you very much for this! While I don't own a Nexus 7, I *do* own an Asus TF700T and this problem also exists on it. On the TF700, this "mode" is active all of the time, no matter what you are doing and it is *very* noticeable and distracting, especially when watching videos (but it *is* noticeable everywhere else as well).
Disabling this "Feature" makes the problem go away. At the very least, you can enable/disable as needed now.
Thanks again!

Hello from Germany,
my Nexus is unlocked and rooted
Terminal:
su
cd /sys/devices/tegradc.0/smartdimmer
./enable
"Permission denied"
change user rights:
chmod 744 enable
(old settings are 644)
./enable
./enable[1]: 1: not found
so where is my fault?
ever since i disabled this gamma destroying feature and my screen keeps getting better and better
starting to fall in love with it really

Care to post how it should be done then? Might be a little bit more helpful
Also, does this affect battery life overall? Or just while watching movies?

You do not "run" the "enable" file. You need to do this:
echo "0" > /sys/devices/tegradc.0/smartdimmer/enable
or
echo "0" > enable (if you are already in that dir).
That will disable the SMartDimmer "feature". Echoing a "1" will re-enable it. I have not noticed any battery life difference....

yes its an LCD battery saving feature and so disabling it will definitely reduce battery life
choose between battery life or quality display

Yes as said in the OP smart dimmer analyzes the video frames and determines whether it can lower the backlight while increasing the color brightness and maintain almost the same image. Lower backlight = better battery life.

After I turned off the dimmer, the screen got a little brighter, so I manually turned down my normal 40% brightness to 30% brightness. So in the end I don't think I'm losing any battery life at all.

I agree - I think any battery life reduction will be *very* minor for most people... I certainly haven't noticed any difference...

Hiya,
Two Qs:
1) Is it possible to remove the LG bootscreen? Reboot the phone a lot and I think it might make it faster. Am rooted and on the latest 10h firmware.
2) Is there an app that effectively puts a brightness slider on the status/notification bar? I wouldn't mind even it was a widget. I tried Power Toggles but it only allowed for a pop up slider which isn't that convenient.
Thanks xda
hi
1> yes it is possible (if u asking for boot animation, not logo) it is stored in /system/media.
2> I also experience problems with brightness when I was using Brightness Level widget but this is sort of LG kernel bug as I can understand cause I got problems with changing brihtness to auto mode

Perfect, thanks for the reply. So I can just delete the animation from .../media?
Yeah, I guess we'll have to wait for the update or patch in a custom rom for that brightness slider.
The minimum brightness of my ROM is still strong, I wanted to know if you have to change the system values to decline further
Re: [Q] How to change the default values of the brightness of the screen?
Use YAAB app from the store..

Which ROM? You might have the ultra-brightness setting ON.
Even if it shows as disabled, try enabling and disabling it again. If you see a huge difference, you've got your answer. Sometimes this option is enabled at each boot, so beware.
Re: [Q] How to change the default values of the brightness of the screen?
Hw-config from system/etc
Better to read some advanced guide cause it's a bit hard.
Tip: you can always change defaults in cyanogen settings / screen settings (can't remember the destination)if you wanna cook rom you can grab saved preference from root/data & put them in a patch.Zip file(easiest way)

On my Note 3 I used an xposed module to give me the option of lowering the screen brightness right down to the minimum that it drops you to when you use the power saving mode. That was one of the modules I was looking for when I moved up to the Note 4 but there's nothing coming up.
I don't want to just use a screen filter, I was looking at something that would enable me to actually lower the brightness right down. Any suggestions? (I'm rooted and running stock MM with Xposed)

Cheers, I had a look at it and it's like a lot of the apps I've seen, it adds a lot of stuff I dont need. Ideally all I want is the ability to drop the brightness lower using the factory slider, not having to mess around with an external app.
I tried it but once it's installed it removes the factory slider when you remove notifications , which is a tad annoying!

It also doesn't go as far as the setting you get when you use the "power saving" mode on my Note 4. You could reduce the contrast but that's effectively just working like one of the screen filter apps. Hmm.
