How to reduce brightness/turn off backligh?

Greetings
I want to save some energy on my Vox, and I'm wondering, is it possible to change (reduce) brightness of backlight on Vox, by using specific program or other trick? Original backlight is really too strong for me!
I've searched for information about it, but I've found nothing...
And if that is not possible, I want to totally turn off backlight. Without it screen is bright enought, I can clearly see everyting on it. Only in good sunny weather could be some problems with it, but I can always turn it on again. So is there any program or other trick to disable backlight?
I founded program called OldSap's OS Power, which should do this. But download page is offline! So maybe someone has got that program and want to share it?
Any solution?
Thanks to all

To decrease brightness you can use Light Toogle from this topic. It works fine with my C600 and should with Vox.
For enegry saving you can also reduce CPU clock (manual with OmapClock or automatically with Tornado PowerControl).

Unfortunately this program doesn't work on my device (it shows only white screen with some chinese "软件大" and do nothing...). Backlight works normal with this program background running...
Other solutions? Maybe this OldSap's OS Power?
It's seems to be easy thing to shut down the backlight, isn't it?

Vox has only two backlight states (excluding no backlight) - full and dimmed. You can use Tornado LowLight or Tornado Power Control to switch between dimmed and full backlight.

torrentonly, thank you very much! This is what I'm looking for!
Program runs perfect, problem solved
Once more time - thanks!

[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

How to develop a screen filter app (for brightness setting)

Hi,
You would have probably come across apps to adjust display brightness by applying a "filter" on the screen, e.g. Screen Filter - does anyone know how to develop an app like this?
I have searched high and low, and cant find out how to get started - any help would be amazing.
Thanks.

Im interested in this topic too Im currently developing an app where the app is active 5-10 min, and its not suitable to let the lockscreen be active. However, its likely that users, and the battery, wants to dim the brightness down, say 50%. But i cant find a way to programaticly to that. Is this so called screenfilter the solution?

Hey, I dont think this is what you are looking for pippi - this Screen Filter app is used to lower brightness beyond what the phone normally allows.
Its probably something like this you need to code...
"WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.screenBrightness = 100 / 100.0f;
getWindow().setAttributes(lp);"
Can anyone help me with my question? thanks...

Aha, thank you very much! Ill look at that tomorrow, got some stuff to do before new years eve, cheers!

Cm7 Automatic Backlight Settings

I wrote down 2 pages and hit post but xda logged me out and now I'm really, let's say it, mad
Hello everyone.
Shorter version:
CM7
Pros:
1. Amazing battery life.
2. More options and settings (after all it is cm).
3. Nicer user interface.
4. Flash player 11 for arm6 is working perfectly.
5. No bloatware.
6. Fast enough and stable (not one fc so far).
Cons:
1. Front cam. Although back one is working fine it would be nice to have a front one as well. Minor issue though, I don't use it anyway.
2. Fm Radio is always turning my bluetooth on when I start it and use it. Don't know if it is supposed to do that but it is a real battery drain and I don't want to use 3rd party apps if that is even possible. This is a minor issue since I don't use it often.
3. Led notification turns green at 90% and more when charging and my phone tricked me to unplug quite a few times Also a minor issue.
4. Default automatic brightness is just terrible. I know that they can be modified through cm settings>display>automatic backlight but I am not sure what values to enter to get the best and optimum results. I just cannot get them quite right.
So, to conclude. Cm7 is just great and really ready for daily use. I only need to set up the automatic backlight properly and this is where I need your help. If anyone knows the best values for these settings, please, write them down in this or the original cm7 thread.
Best wishes

I've set the status bar notification for backlight to 25/50/75/100. I feel that these values suit every possible condition.

Hi Alex, you must have misunderstood me. I'm not talking about those settings. I don't want to adjust brightness manually. I'm talking about window length, reset threshold, sample interval and custom light sensor levels so my phone can automatically adjust brightness. These can be found in cyanogen settings>display>automatic backlight

Ah, ok then.. Unfortunately I did not have the patience required to set/tweak them.

Fix adaptive brightness (windows rt/8)

I customized a luminosity curve for my surface rt, just edit the registry keys.
Download extract and run the attached .reg file and confirm the insertion of the Keys, then reboot the system.
Alert to make a backup of the old keys if you want to restore the previous state.
This change is compatible with all windows 8 but I have tested only on the surface.
Adaptive brightness varies proportionally to the user manual brightness, I suggest to manually adjust the brightness bar to about 20%, if you place the bar at 0 the brightness will be minimal with no automatic adaptation.
Appreciated thanks
New version v2
New improved version.
Try it and tell me if it's okay.
In the zip you will find the normal version and one with more brightness in the dark
I suggest to manually adjust the brightness bar to about 25%

So you have a fix, that's great. But to what? You didn't state what the problem is. Neither did you way what you are doing differently over the default values. Why would me, or anybody else for that matter, want do download this?

In my surface the luminosity curve does not satisfy me.
The display seemed to have only three levels of brightness, setting an average value (ie on the desk in the room in the morning) adaptivity did not fit values ​​for low-light (night) and lots of light, that is to say the brightness in the dark was not a minimum making it annoying for the view and unnecessary consumption of battery, instead with shaded light levels brightness became easily maximum, with again a waste of battery.
This forced me to move often the brightness bar manually, but now with my calibration does not touch more because it adapts automatically to any light condition.
Also the adaptation of brightness occurred after 3 seconds by the change of light, whereas now changes instantly in 0,1 seconds (100ms).

I like it a lot, just what I was looking for.
I use mostly in low light conditions my surface so it is very useful.
Just one remark: it is too sensitive so it is changing screen brightness very quickly even when I just touching the upper part of the screen and making a little shade on the light sensor...
So I think instead of 1 msec. would be better 3 msec.
Would you please and make a 3. version of the settings with 3 msec.?

100ms not 1ms! However, this file will change only the time in 300ms

You are right, 100 ms. I was in a hurry. Thanks for the fast response and update

Your v2 seems to be working fine for me. Before applying it I could really tell when my surface was adjusting the screen, after applying it the transitions seems smoother and less abrupt.
I have been looking for documentation about how all of these things really work and the closest thing i could find was this link http://superuser.com/questions/644538/customize-adaptative-brightness-in-windows-8
but they seem to be using a different registry location than what you are and different registry names
regardless your settings seem to work immediately after restarting the sensor service
