Peoples....has anyone found a way to "tweak" the auto adjust backlight setting?? Would be nice to be able to set the light sensor to a pre-determined value so that it is always that value greater than the ambiant light...
Why??...well, I would like to continue using the same auto setting (saves battery, etc) but have it just a little bit brighter than what it is doing automatically at the moment.
I'm sure there is a way....would be great to have this in Shaps AC or Diamond Tweak....hmmm, perhaps post there to....
Thanks all
Not sure if this helps, but if you untick the box for auto brightness then you can slide the brightness control up and down to set the base setting then re tick the auto box. Let me know if this is what you are wanting. If not just ignore me

Nice one, but unfortunetely does not have the desired effect (just checked)....
HOWEVER, this would be a great why to build it into the system i.e. manually set the level thats works best for you in the abient lighting of the moment....then set auto adjust to keep that differential...hmmm...
I would love to find a way to calibrate that. The backlight in darkness is too high for my eyes. When I set it manually I can decrease the brightness to a comfortable degree, but as soon as I turn automatic mode back on, it gets higher.
Agree

Same here.
Is there any reg key to set up the minimum value for bl when in darkness..?
Anybody knows ?
Thanks
advanced config v 3
try with it,i ran into few tweaks for light sensor,hope it'll help you
Nope, Advanced Config's light sensor tweaks are only for the new Phone app.

Nothing easy to recognise in the Registry...I think this might need a "power" developer...
....er, thats definately NOT me
i found this:

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 !

Thank you. Its a lot of attention you have given this topic. For that I thank you. - Just too bad you cant find that dll. :-/ Hope some other helps.
backlight.dll found in Windows folder

Thanks, for reference, there are the functions:
Code:
BKL_Close
BKL_Deinit
BKL_Init
BKL_IOControl
BKL_Open
BKL_PowerDown
BKL_PowerUp
BKL_Read
BKL_Seek
BKL_Write
inside the Backlight.dll
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.

This tweak still dosnt make the phone use the whole scale. From dimmest to brightest. :-/

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.
I've seen a few references to making the "backlight" (brightness) lower than standard but I haven't found what can do this yet.. I don't need/care about a widget, I want to use it programatically in Tasker to say set the brightness to minimal or maximal in a sane fashion... Changing it in Tasker seems to have Android induced limitations.
Also, perhaps separately, would be nice to have a program which you can adjust the auto brightness sensitivity and have more control over it.
Thanks for any suggestions!
There is an app in CM6 that does this, it's really good, you set screen brightness for different light conditions. It can be set lower than standard brightness and you can have as many different brightness levels as you want.
I haven't been able to find this to use with any other ROMS, but would really love for it to be included in Enoms Rom.
The description of this app on the CM6 changelog is
Configurable brightness sensor - Jonas Larsson

Aha, yeah now that I searched for his name I see a few other requests for this outside of CM6... Maybe someday.
I find that the auto-brightness on our phone doesn't reduce to the minimum possible! Is there a setting I'm not seeing?
I always use the widget to control it because it can take it much lower than the auto brightness does.
...so are there any fixes, or would we need a custom kernel to be able do that?
Auto brightness is just very inefficient. I've been using manual brightness on this and my previous phone for a long time. You could use an app such as Screen Filter which reduces the brightness, but it seems to make the colours look a bit washed out to me.
With regards to a custom ROM or kernel, I have no idea whether this would help, but I've never seen changes to the auto brightness function on any previous custom ROM I've ever used.

From what i know, You would need a custom Kernel.. try getting ' My Settings ' From market ... gives as much control as possible to ur stock ROM for screen brightness as possible along with a host of other useful toggles.
Be sure to add a SHORTCUT onto ur home screenm for easy access
it has improved my battery life quite a bit !
I don't understand how they could screw up such a simple thing!
I'm running froyo... does gingerbread fix the auto brightness?
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 ?
