Backlight Off Level

I have a question, not sure if it is possible.
I have an O2 Atom running Jiggs WM6 0.7 ROM with Backlight Off set at 30 Sec. Is there a way I can set the backlight off level to any number between 1-10.
This is what I want :
1) Phone active - backlight 10
2) Standby - backlight 5
Anyone...Anything...???

as far as i know it's on or off for backlight
not a lightsource that can be regulated

Change the backlight <-> camera brightness.

I'm a old palm user, and on my Treo I used a program that could change the back-light to a lower level when it was dark.
It simply measured how "bright" the camera was. If the "picture" was dark then it changed the backlight to low. A very cool program that made the phone more "easy" to use at nights. And it did it completely automatically.
Is there such a program to the vox, or is the only thing I can do is to load one of the programs where I can change the back-light manually?

How to disable backlight for keypad and D-Pad?

As we can see - default timeout value around 10 sec. But i can't find how to disable it.
Anybody can help me?

Changing registry keys:
HKCU\ControlPanel\Backlight\KeylightTimeout (default val. 15000)
HKCU\ControlPanel\Backlight\LightDetectOn (default val. 1000)
HKLM\Services\Keypad\DisableKeyLight (default val. 0) has no effect for me.

Did you just change it, or also soft-reset?

Of course soft-reset.

O2 one doesn't come with a D-pad light. Maan I wanna kill someone...

Amswer from htc.
"???????????????????????????????????? I have looked at the cruise and also i can not find anyway to deativate the lights on the keys, so there is no way to deativate them.Sorry about that."
Idots?

Another answer from HTC.
"I am very sorry for the delay. The answer to your question is you can adjust the backlight for the screen, but not the backlight for the keys. There is no update planned for this issue.
I hope this is an answer to your questions. "
I think - this is not true. You opinion?

[APP][26-10-2009] AutoLight V2.5 - Better Auto Backlight for Topaz

AutoLight V2.5
HTC Topaz (Diamond 2) auto adjust backlight function is a good idea with a not very good implementation. It must be said to HTC excuse that the light sensor is very noisy, especially at low light conditions.
Some alternatives do exist but are not very good or are Compact Framework application (not a very good idea for background application).
AutoLight is supposed to be a better implementation for the auto adjust backlight function.
Requirements and compatibility
AutoLight was developed for HTC Topaz (Diamond 2) with WM6.1 and it critically depends on HTCSensorSDK.dll, HTCUtil.dll and on a 10 levels backlight starting from value 1.
It has been reported to work with WM6.5, on Rhodium (Touch Pro 2) and on Leo (HD2) and it might works on other HTC phones but the test is up to you. I do not think it can work on non-HTC phones.
AutoLight is a native application with a very low memory usage. On the other hand the Configurator requires Compact Framework 2 but it should be closed after the use.
The Configurator is designed for WVGA screens.
Install
Run AutoLight.cab and install in main memory (not in storage card), run AutoLight.Config.cab and install where you like, then softreset (this should also disable the native auto adjust backlight function, check for that in the Control Panel Power applet).
If you have previously installed autolight V2.x and want only upgrade to V2.4 without having your configuration reset to default use the Configurator to stop AutoLight. After that overwrite AutoLight.exe, ChangeLight.exe and AutoLightConfig.exe with the files you find inside AutoLight.zip and softreset.
Uninstall
To uninstall AutoLight use the Configurator to stop it, then use Remove Programs in Settings.
AutoLight can be also be stopped running the AutoLightStop utility.
To uninstall AutoLight Configurator use Remove Programs in Settings.
Configurator
AutoLight working depends on parameters it gets from registry. For details on parameters see AutoLight.reg.txt and AutoLigth.reg
The Configurator gives a more user friendly access to these parameters. Nevertheless, the configuration process is quite complex and should be done after thoroughly reading AutoLight.reg.txt.
The second tab of the Configurator contains a graphical representation of the calibration table used to convert light sensor to backlight values. Note that:
- the horizontal scale is not linear but goes according to square root of the light sensor value;
- the horizontal red segments represent the ranges of light sensor values assigned to every backlight level;
- the horizontal red segment whose backlight level is selected (with the control on top of the second tab) turns blue;
- the small rectangles connecting the segments are the hysteresis;
- the vertical blue line is the current light sensor value (only available when AutoLight is running);
- the horizontal blue line is the current backlight level (only available when AutoLight is running).
Freeze backlight command
When you use your phone in a rapidly changing light environment AutoLight keeps hunting the right backlight level. For example, this may happen using a GPS navigator inside a running car. The freeze backlight command solves this kind of problem by keeping the backlight level stable from the moment it is invoked.
To freeze the backlight level run ChangeLight.exe without any parameter. Using ChangeLight.exe and a hardware button mapper you can freeze the backlight level just pressing a button. From then on the backlight level remains stable until you run ChangeLight.exe again, power your phone off or change power from AC to battery or viceversa.
User offset change and increment/decrement backlight command
If you are not satisfied with the backlight level as computed by AutoLight you can add a positive or negative offset to it. The offset values, one for use when on battery and one for use when on AC power, can be entered using the Configurator.
Moreover, running ChangeLight.exe with parameter "/-" decrements backlight level by one, with parameter "/+" increments backlight level by one. The utility then adjusts current offset level accordingly. Using ChangeLight.exe and a hardware button mapper you can change backlight and offset without using the stylus.

I'm a bit confused. What exactly does this do?

How is this different than the excellent LUMOS?

i tried lumos & g-light and eventually got back to WM6 default autolight & its working pretty good.
how this app different/better than default autolight?
because its starting from level 1 not from 2?

It changes backlight according to ambient light level.

Lumos (and G-Light) are not bad but they use Compact Framework even for the background always running process. Use a task manager to see how much memory they consume. Moreover, under stress condition (many running applications) a Compact Framework application can be forced to close.

Yes, because it starts from level 1, not 3 (at least on my Topaz is 3). Moreover, it's more configurable (if you are experienced enough to tweak the registry) and because with version 1.1 it can change backlight for different applications (details inside the zip).

Works well on WM 6.5

Cool, thanks for answering the questions. I'll try it out.

Version 1.1.1 posted.

Hi,
Does not work with T-Mobile variant of Touch Diamond 2.

Wold you be a bit more specific?
Does not install?
Does install but AutoLight.exe does not start?
AutoLight.exe starts but does not regulate backlight?

Thanks a lot, Great work
Exactly what i'm looking for.. I will keep this..

Hi
It installs fine, it just does not affect the backlight at all.
Regards

Great App!!!
In the list of task process, autolight used 3.70kb. (very little).
I have one question, how work the battery consumption of the program? Comparing the original autobaklight or the third level of backlight?

The program only runs when the device is active and does very little (it mostly sleep) so it adds almost nothing to battery consumption.
Consumption due to backlight of course depends on external light. AutoLight is darker than original service at low light level but brighter at very high level.
If you want to aggressively save the battery you must change the calibration curve to keep lower backlight levels. Inside the zip you find details on the calibration curve and how change it (registry tweaking and patience are required).

If you are sure that the AutoLight.exe process is running and that the original autolight service is disabled (from the control panel power applet) I must suppose that your branded device is somewhat different enough from tha standard Topaz to prevent AutoLight working (maybe some extra security settings).

Do you plan to make configurator for those who do afraid to directly edit the registry?

I really do not have enough free time to write a decent configurator and I prefer to concentrate on the core functionality (I want to remove the "flash" on power on due to sensor setup).
On the other hand the program is free (and copyright free also) so if someone wants to write a configurator...

May be off the thread, but can you tell how much its possible to change light settings in direction of brightest level?
I have CMP (ComMangerPro) running at that excellent program control my light settings according to schedules and places. It could be rather cool to give more light when I have chosen the highest level?

[APP] AutoBacklight Toggle + Steps [29/9/2010]

I created simple app to turn auto-backlight function on/off really quickly. I missed that feature on my HD2 and the need of doing 5 moves to get it changed was not much user friendly. So here is the solution!
Edit 2010/09/29:
Thanks for all your comments and ideas. This lead to following two versions that looks to be final.
AutoBacklightToggle (last update 2010/05/30):
Simply install the CAB below and you will get new program in Start menu called "AutoBacklight". When you tap the icon, it changes your auto-backlight setting from on to off or backwards based on your current state. Simple and effective.
AutoBacklightSteps (last update 2010/09/29):
The "Steps" are extended version of toggle. You can set predefined backlight settings that will be called each time you run the app. Let's say you select 10, 50, 100, Auto. First time you run the app, the backlight is set to 10%, second time to 50%, then to 100% and finally to Autobacklight. In next step the 10% setting will be back again.
There were few changes done on 09/29 (v1.0):
- the backlight is set to the same value for both the battery and external power.
- everyone can select what the steps will be (see below)
- everyone can select if he wants the change to be confirmed by pop-up window (see below).
Setting AutoBacklightSteps:
1) There is a new TXT file in Program Files/AutoBacklightSteps folder called AutoBacklightSteps.txt. All the setting is done in there manually.
2) The first line is used to adjust the steps. You can use numbers "10, 20, 30, 40, 50, 60, 70, 80, 90, 100" or character "A" which means autobacklight. Separate all steps with comma, otherwise it will not work. I attached the default TXT file to this post for reference.
3) The second line is used to turn the notifications on/off. Write there Notification=1 to turn it on or 0 to turn it off.

What exactly does the program do? Is Auto-backlight depending the light sensor?

Yes. Auto-backlight uses the light sensor to adjust backlight. This function can be turned on/off in setting but it is hard to get there so I made simple app to toggle it using one tap.

Thanks for the info and for the app, of course! Can be quite useful!

Good stuff! Much thanks.

Just had a genius idea. Is it possible that you could dim/brighten the backlight by holding in a hardware key? ie. Hold the button then it brightens gradually to 100% and then back down to zero etc.

Yes, you can use AEButtonPlus app and use your volume buttons to control your backlight in two stages by long pressing them (short press volume control). Low- medium-high. I love it and use it all the time.

If the default auto-backlight solution is too annoying you could just use Lumos... just Google the xda forums for it. Been using it from Touch HD to now and still works great.

I made something similar just a little while back that also functioned as a launcher for haret (ie, to launch Android) on the TP2. Are you just toggling the registry key, or are you directly controlling the function?

I love it! it's awesome!

thanks for this cool app.

Just what I wanted! THX!!!

Thanks for making this, now i can acctually SEE what happens on the screen in sunlight easily

Yep, just changing registry value. It is good that it takes effect immediatelly after you change it.

Ya, I was surprised to find that it seemed to take effect almost instantly. How do you suppose that works, some HTC program constantly polling that value?
Is it "HKEY_CURRENT_USER\\ControlPanel\\BackLight", "LightDetectOn" on the HD2 as well? I wonder if it's consistent across HTC devices.

just want to share this wonderful finger-friendly app to change the backlight and , like this app, turn on or off auto-backlight. it's called myLight. check this website for more info and download: http://mylostblog.altervista.org/my-software/mylight/mylight-04
under menu or settings, you can switch on or off the auto-backlight and if it's off, you can manually adjust the backlight easily.

thanks 4 sharing this app =).
a notification messagebox would be nice.auto backlight on/off
best regards

will this work on a tp2 or any other device? im assuming it could since all its doing is changing the registry and theyre very similar, right?

Thank you very much \(^_^)/
Outstanding! It is just what I was thinking today... I need a AutoBackLight toggle function, because I like to have my screen on 90% (in battery mode) but when I'm using it to maybe just read (white text on a black background (which I wish there was more of)) for long periods, want to save a bit on battery life or in a fairly dark room, I want to be able to easily switch to 'auto' and back again when required.
Thanks very much... will try it for a few days at least and let you know how I get on! [^_^]

Thanks for this nice Tool
best Regards
