[Q] duration of backlight on hardware keys - LG Optimus 3D

hi there, could some one help me work out how to control the duration of the bottom touch capacitive keys on my lg p920 3d, as they only stay on for 6 or 7 sec i need them to stay on while im using it,as at night its just not possible to know where the keys are!my old lg p970 black had it and the led lights would stay on really dim but enough to see them,so if you can post a link or know of a app that can do this let me know

Try this: http://forum.xda-developers.com/showthread.php?t=1216824
It will keep the LEDs on while the screen is on. And it can do some other stuff.
But it is not possible to reduce the brightness of LEDs.
Over the time you will find yourself remembering the position of the 4 keys and maybe the function to reduce the timeout of 6s to lower values will come in handy

{HOW} do i make the LED light stay on longer

how do i make the LED light on the touch capacitive buttons stay on longer
IE: the "Home" key the "Search" key (all the keys at the bottom of the phone)
they stay on about 10 seconds and i need them to stay on longer
i can not see them unless they are lighted
while i am getting pretty good at guessing where they are at when they are off.
i would still like them to stay on longer so i would not have to guess
i have Dimmed them in the "Hidden Menu" (Because i thought them too bright)
there was no where to set them to stay on longer
staying on for 30 seconds would be ideal
anyone have any idea on how to do this ?
thanks
just touch the screen and they come up.

the LED Notification app lets you tweak your touch buttons for brightness and such, but I don't know if there is a setting to adjust how long they normally stay on while inactive.
The developer could probably add that pretty easily though.
Something like that will kill your battery

Backlight

Is there any way to completely disable the backlight on the samsung galaxy s 4g?
What I mean by this is that I don't want the soft keys on the phone to light up at all
I would like to see a reply to this as well...I use Screen Filter and it does a great job at dimming the screen beyond the minimum I can with Android, but it doesn't affect those buttons...they're blindingly bright in a blacked out room...

Prevent Light sensor from switching off LED buttons?

Hey guys, I'm running Khalpower's V4 (following the video tutorial which was great)
I realized the light sensor now controls the 4 lit buttons at the bottom part of the phone. I'm okay with it but I realized that sometimes its not accurate and it really distracts me going on and off. Any idea if I can turn off the light sensor controlling when the buttons are lit?
Thanks!

[Q] Help with hardware buttons - brightness

Anyone come across a place in the code where you can configure the brightness of the light behind the hardware keyboard and the hardware buttons on the face?
Here's the deal, the buttons on the front facing of the phone are just too damn bright, and now that I have one of those privacy-shield screen protectors on (love it, btw) the hardware buttons are way too bright, about 3 times the level of light that emanates from the screen.
I desperately need to figure out how to dim those front face buttons, because it's really screwing with my eyes while i'm trying to work with the device.
Everything I search for on XDA comes up with using the hardware buttons to set the brightness levels, but nothing about setting the brightness levels of the backlit buttons themselves.
While we're poking around on it I figured we should see about the brightness level of the hardware buttons on the keyboard, too. I think they're fine, but someone else might want to adjust it and it stands to reason to concentrate the info all in one spot.
Anyone come up with a clue while browsing through the device, or know how to do this? I don't want to lose all the illumination, just dim it a bit.
Thanks!
Clue 1:
In kernel source, /arch/arm/mach-msm/board-doubleshot.c
Around line 2300 some info defined.
More as it's found, going through all kernel source line by line takes a while.

How do the soft key lights work?

The soft key lights on this device seem to work differently then most other android devices with back light soft keys. I've been trying to figure this out for a while. When exactly does the phone decide to turn them off, and and why can't I turn them off using apps like screen filter, and even on the stock t mobile rom?
Is this a hardware or software issue?
What I know is that the soft key lights in kj6 (gingerbread) roms turn on every time you turn the screen on or touch the screen, and turn off after 3 seconds of inactivity (not touching the screen or pressing any buttons).
But it seems that in some situations the soft keys turn off and stay off, even when touching the screen, which is seemingly random. Why does it do this?
Does anybody know when exactly the soft key lights decide to turn off?
From what I can tell, the Team Acid ICS driver does what it is supposed to do -- turn on and off the lights when the magic number is written to the right sysfs location.
The control of the lights is supposed to happen in the Android world with PowerManager and LightsService. The "problem" is that it seems as though the chip that controls the touchkeys and their backlight have a mind of their own and turn on the lights when you touch them. This gets the Android world's idea of if they are on or not confused, resulting in LightsService not "turning off" the light as it thinks they are already off.
I'm working through a good way to resolve this. Messing with the framework code is not the best as it means that TeamAcid would have their own version, and keeping up with upstream changes would be more difficult. Unfortunately, how it was done in GB is something of a mystery as it isn't clear to me from the Samsung code drop.

Are the soft key lights on the sgs4g the same as the original us versions of the Samsung galaxy (the vibrant/captivate)? If they have a fix for this (I assume they might because they have a larger development community) , would it work for our device?
I'm looking into if I can find some dev information for the Cypress/Melfas key controller, and possibly the Atmel mXT224 and looking for other devices that use it (Motorola Atrix, for example). If I can disable the "LED on when touched" behavior, things are a lot easier.
i was wondering about this as well... my back button, is messed up and has no sensitivity at all so im trying to disable the whole bar and just use an onscreen nav bar. i know that paranoid as it in their settings but that rom eats up the battery like a mad man ill be down to zero by noon i dont get that problem with CM9 BUT CM9 doesnt have the onscreen Nav Bar
does any one know where i can find more info on adding this nav bar to CM9?
Aokp has it too

You might try Hefe Kernel Of Darkness (second post in that thread) to mainly turn off the touchkey backlight.
I'm curious as to what poor back-button sensitivity problems you are seeing. You can PM to keep the thread clean.
