hi
is there any way to disable the led of the hardware buttons. i know where the buttons are. i dont need a light to find them. and it looks ugly when they light up. after i used them i always wait to touch the screen until they are off.
I think neldar knows the most about this since he has done the backlight notifications mod. It would be super to have an option in the recovery to disable backlight in the buttons. They are annoying at night when using Screen filter to dim the screen, buttons are very bright in contrast to the screen.
Agreed. I would love to be able to switch them off.
Yes this is true and really anoying!
At night they are much to bright. Would love a "disable" option, too.
Is it maybe possible to dimm the buttons, too?? This would really be awesome
ok, i'm not the only one who wants that leds switched off. but isn't there anyone who has an idea how to do that
Anyone figured this out yet?
i found an app in the market called“ leds hack“. it supports samsung vibrant, but it dont works on my phone. isnt it the us-name for the sgs? maybe the rom is the problem. i'm on darkys 9.3
i tryed to find the script that controls the backlight. here: stackoverflow.com/questions/4152053/android-turn-off-key-lights i found this info:
A: The keyboard backlight can be controlled via /sys/class/leds/ keyboard-backlight/brightness. It appears that it's a simple on-off control (echoing '0' turns it off, echoing '1' or higher turns it on). For some reason, the default system backlight control stuff seems to set this to "83", but I don't know why. I can't seem to see any difference between 83 and any other number. The file is readable by anyone, but only writable by root, so you'll need root access to the phone to manipulate it this way.
can anyone tell me where i can find the file on my phone...
Has anyone found the answer?
This is honestly something that I would even pay for if a dev wanted to create a little app or mod that could do this quickly and easily for those that are not confident to make these changes on their own.
No one? :/

this doesnt exist on our android.
There is is /sys/devices/virtual/misc/melfas_touchkey/brightness
you can do
echo '1' > /sys/devices/virtual/misc/melfas_touchkey/brightness
to turn it on, but i have not found a way to turn it off permanently
Can some one bind this to light sensor? So that we can have it disabled during day and have it enabled at night??
how can i edit this files? i cant find an editor or something like that. i'd like to play around with this script?

I don't have the folder /leds. What version of android do you have?
I found this. As a new user, I can't send links to the forum, I paste the important part:
Samsung GT-I9000
s3c-keypad
- scancode = 26 (confirmed with keylayout/s3c-keypad.kl)
/sys/class/backlight/s5p_bl/brightness
drivers/input/keyboard/s3c-keypad.c
drivers/video/backlight/backlight.c
- brightness and actual_brightness 's get/set method. (actual_brightness is read only)
drivers/video/samsung/s3cfb_tl2796.c
- Samsung's implementation. MIN_BL = 30. Lower than this == black out.
Could it be useful?
Thanks

Hi All.
I have wondered why the software that controls the backlight, with the light sensor, doesn’t adjust the backlight to the lowest setting, when the phone is in total darkness.
I use my phone in complete darkness almost every night, but I think the backlight is way to bright. I know I can adjust it manual, but why not automatic?
Do any of you bright heads, know a reg value to change or another solution, so I can "allow" the backlight to go to the lowest setting, automatically?
I find this anoying also. Any help would be great.
Anyone? I have looked in the registry but cant find anything... :-/
as far as i know there is no software\tweak that can change backlite to min
Same here. In my case, I'd like the backlight to be a bit brighter in brighter conditions, especially when in the car on a sunny day and I'm using iGo. Manually, I can set the backlight higher. I had a sony ericsson phone with a similar light sensor, but you could adjust its maximum threshold and the general brightness. Surely there's a software solution here somewhere!
I searched a little and quickly found some things:
1. The Diamond seems to have an in-built process to adjust brightness according to light sensor. Don't know if it works, though.
2. The registry keys are found at "HKEY_CURRENT_USER\BackLight\". You can modify brightness there, and it will affect the control panel BUT not change your current brightness. There is an Event you must trigger to update brightness. In many devices, this is the BacklightChangeEvent, in some others, this is SDKBacklightChangeEvent, and some others something different. Depends on the device and the manufacturer.
I wrote an app to change the registry value and trigger both SDKBacklightChangeEvent and BacklightChangeEvent. I can see on the control panel the value has changed, but the visible Brightness won't change. Seems HTC decided to make their own DLL to manage that, instead of standard windows mobile events.
So, I searched a bit further and I found that into "HKEY_LOCAL_MACHINE\Drivers\BuiltIn" there is a key called "Frontlight" which is apparently defining a value which points to Backlight.dll. This must be HTC's implementation of the Backlight manager. I was like "yay this will be my first windows mobile dll reverse engineering" BUT, I didn't find this file anywhere on the device, unfortunately.
If anyone could find it on the Diamond, please pass me the info !

This has to be a lot easier.
I found some reg settings in HKCU\ControlPanel\BackLight, one of them called "AutoBklOffset". Actually this is exactly what we're searching for here: When I enter a value >0 here, the backlight instantly goes brighter, and the automatic backlight setting is still active and works.
so, what we have to do is figure out how to enter a negative value here.
Ideas?
Hmm, I don't think we can get anything only with the registry, but we don't lose anything to try, do we ?
I'll check again the registry.
Ok. Actually AutoBklOffset is linked to "Auto backlight adjust". This means that if auto backlight adjust isn't ativated, AutoBklOffset won't do anything.
Ok, all this search was fun. But I told myself: what if I just go ahead and try if the already built-in app works ?
And yea, it already works. Meaning if you put the device in front of the sun, it will go bright, and dim if you're in a dark place.
So I guess this is a configuration specific issue and don't need a new app. I'm out of tha place !
P.S.: It would have been actually quite stupid to include a Light sensor but not using it.

You misunderstand the issue.
With the backlight set to auto try using your phone in a completely dark room - the light sensor will detect this and the phone dims. Okay, now remove the auto setting and you will find that you can make the phone even dimmer than this using the slider. The lowest auto setting is equivalent to level 3 on the manual scale - what the guys here want to do is make this equal to level 1, or lower (or in the case of one poster make the maximum auto setting equal to the maximum manual setting, or perhaps even higher if possible).
The issue is therefore not whether or not the light sensor works (it does), or whether the phone can automatically dim/brighten the display in response to the ambient light level (it can), but whether it is possible to make the full scale range in automatic mode equal to that which the device offers in manual mode.

Spot on!
Hi friends.
I have the problem using TomTom at car. When Diamond receive direct sun light it increases backlight until 70%, but not 100%; when I drive at night Diamond decreases backlight until 30%.
I would like adjust some values to 100% and 10% but I have no idea about registry or dlls.

Did you come any further with the app?
I too would like to see a solution for the narrow range of light sensor adjustment. The screen stays too bright when ambient is dark.
In my Sprint CDMA Diamond, I see these registry entries:
HKEY_CURRENT_USER\ControlPanel\BackLight
LSensorReduceBKLDelay
LSensorAvegQuene
I wonder what they do. There must be some way to change the range of adjustment or the bias of the light sensor.
First off, I apologize to anyone who looks at this thread thinking that I am posting another screen brightness program. On the contrary I am LOOKING for a program that will allow us to control the brightness level of the phone in small increments.
Before the Fuze I had the HTC Touch which on the homescreen had the option of pressing the brightness shortcut and it would jump the brightness up a notch and then reset down to the lowest value once it got to the highest. Anyone that had this phone or a similar HTC phone that ran..... HTC Home knows what I am talking about.
While using the fuze I have always wondered why I couldn't find anything like this for newer phones. Searching for the longest times on a number of different forums left me with nothing. The automatic screen brightness control of the touch pro is less then desirable. There's times when my phones plugged in but I'm reading news in bed and I want to be able to have the brightness set to low without having to go through the settings and bugger around with it all.
That said, does anyone know of something that will do this? Or is it possible for one of the awesome program developers here to create something like this?
Here's a screen shot just for referance. By pressing the lightbulb it would change the screen brightness of the phone.

Thanks for the link and I've changed the subject title. I can't believe I didnt put that in there... That's a Newb mistake
edit Mylight. my lord I remember seeing this post AGES ago when all it was was a graphic "idea" and didnt actually do anything. Glad it got off the ground!
I need some help with options in this phone. First off all I found it annoying that the bottom 4 touch button light turns off in like 5 seconds. I know it saves battery but I want to have the option to keep on longer. I'm pretty sure there isn't a built in option, but is it possible for anyone here to mod this? (I think you can do it because there is a mod to turn them always off).
Next I feel that the lowest screen brightness is still pretty high. Is there anyway that I can reduce it? Possibly through an app? I'm rooted and everything so no problem there. Thanks
Many would like the option to change the time out on the buttons. Unfortunately no fix yet.
As for the brightness, many of the widgets to adjust brightness from the market will allow lower settings
I use extended controls..I don't think it was free but is highly customizable
This tweak is no longer supported, use Touch Wake instead!
For notebook/netbook computers switching off the screen after a certain timeout is a simple yet effective way of saving battery life and such a feature is integrated into every OS. Android also has a screen timeout feature, however this suspend function also disables the touchscreen controls (and touchkey buttons) and you have to press the power button to re-enable the screen (plus, if you did not disable the lockscreen, you also have to unlock it again).
Since this is kinda annoying I tried to find an app which could disable the screen after a timeout and re-enable it on touch, however I could not find one. After some digging I found out that there is no way with the current Android API to disable the screen without simultaneously disabling the touchscreen controls.
So I took a look at the kernel source and after some trial and error it seems I have found a stable way to implement such a screen off feature.
To enable (disable) the screen dimmer pass 1 (0) to 'enabled' in /sys/class/misc/screendimmer. Pass the delay in ms (this is milliseconds; 1000ms = 1s) to 'delay'. The default state is disabled and a delay of 15000 = 15s.

Yes, unfortunately the screen always gets dimmed even if the app has the FLAG_KEEP_SCREEN_ON set. I took a look at the kernel source and it seems this flag is not passed on to the kernel and handled only by the Android OS; so the kernel does not know whether currently an app is open which has this flag set. Maybe I can think of something, but most likely this is a limitation which I cannot remove.
This will be amazing.
I have always wanted a way to wake up the phone without reaching over to the power button. I remapped my power button to the soft search key just so I didn't have to reach over to push the power button but it obviously didn't work to wake the phone. This is something I've dreamed of, to just touch the screen or the touch keys and it would wake.
Couple questions:
1) Is it possible that only touching the 4 soft keys will wake the screen (instead of the screen)?
2) How does this affect battery? Is a wake lock held? Does the phone sleep correctly to go into power saving? I'm assuming if the screen is touchable that the phone isn't sleeping and as such, this will be a battery drainer.

1) Currently the screen is re-enabled both when touching the screen and the touchkeys. I think that makes the most sense. However, one could easily modify the code to limit this to the touchkeys.
2) The phone is not put to sleep, only the screen is disabled. So compared to the normal screen lock this will drain the battery much quicker. This tweak is not intended as a replacement for the stock screen lock, but as an addition. You can set the screen lock to a value like one or two minutes, so it will properly lock the phone for example if put it in your pocket, while having the screen dimmer set to a lower timeout like 15sec, so the screen will be disabled and some battery saved if you just pause for some time for example because you wait for a download to finish or talk to somebody. So, if you use it right, you should save some amount of battery.
I found a bug after running this mod for about a couple hours. The screen would not turn on after leaving the phone for about half an hour. The touchkeys would light up and the when I clicked the volume keys I could hear the volume settings changing.

Hey guys, as you all know, there usually is no way, of how to control led brightness and duration in a stock ROM, except for Zeus ROM. Now I just found a way, of how it probably could be controlled, but I dont know, how to set it correctly... Just open the hidden menu (3845#*970#), then go to device test, scroll all the way down, to LED current control and there you can set different things, but I dont know, how to set it correctly... can anyone explain the settings maybe or even build an easy to use app, which would allow all of the stock users, to control the LED brightness and maybe even the brightness of the LEDs.
And I also discovered, that with some random settings i chose, my softkeys all are illuminated blue, which I like very much, maybe also a feature, that is settable somehow... Would be really cool, if we could use this somehow. There also are some paths, that show, which file is being used, but it doesnt tell me anything, so maybe someone here can take benefit of it I hope so
I would love yo have them all blue
hmm, I don't get the point. when you control screen brightness, it's leds brightness logically... I mean, it's global. decreasing brightness decreases luminosity of leds light. backlight is about zones or areas.
My point is, I first of all want full control over the Softkeys. I want to be able to set color, duration or permantent light and also the brightness of the softkeys. I for example would like to have them blue at full brightness and permanently illuminated, since I hate it if they go out completely and I miss the right button... I know, it's not that much of a deal, but dont you think as well, that it would be cool, to be able to control it? It's not about the screen brightness, but only about the softkeys. Get what I mean and want?
okay I see. there is the notification app already which control a part of softkeys. maybe you could understand how to control them if you're able to decompile the app to see the source code ?
