Auto adjust backlight toggle - HD2 General

I have the backlight set to automatically adjust, but when I am using my phone in the dark, I like it fixed at 10%.
Rather than going through 6 screens to manually update it every time, I would love it if someone could come up with a button (like the WiFi switch on windows market place), so that I can just hit a shortcut on the today screen and the auto adjust is toggled on and off.
The registry entry that turns the auto adjust on or off is called
HKCU\ControlPanel\Backlight and the key is Light Detect On
Any pointers or help would be appreciated!

you can make a link that opens the backlight page directly.
see the "control panel items" link in my sig.
not quite a toggle but reduces the clicks to 2.

Just made a request thread for this yesterday
http://forum.xda-developers.com/showthread.php?t=675898
Think it would be a good quicklink for sense

To be honest, I saw your thread back along and didn't quite get it. I do now though!
Can't wait to get home from work and try this. Not a complete solution, but it will certainly save me a load of hassle.
Thanks!

with ya pal!
what gets me is the sensor, when its dark its at full brightness, when its light its dim...... shouldn't this be the other way round?

[APP][Updated 29/08] Flashlight v 1.2

Have you ever been alone in the dark with only your cherished Diamond wishing you had a better light source than its dark theme can provide? It certainly happened to me, and here is the solution: Flashlight.
Why a new such program when a few freeware already exist? Well, this one is TOTALLY finger friendly.
While in the main screen, drag your finger upwards to increase the light or downwards to decrease it.
The program can also be used as an emergency beacon, flashing two colors. To set the colors, again move your finger (horizontally this time) on the red, green or blue markers. The settings are saved on exit.
Compact Framework 3.5 needed!
Update 24/08/08 v 1.1
Added SOS function. This uses Color1 from Options.
Update 29/08/08 v 1.2:
Added menu item to disable Auto backlight. This allows to get maximum luminosity. The program will remeber the setting. When exiting, it will restore your backlight to what it was before.
To use this facility with the best results, do the following:
Start -> Settings -> System -> Power -> Backlight
Uncheck Auto adjust backlight
Slide both cursors to maximum
Check Auto adjust backight
Now start flashlight, go to Options, click on Auto backlight (to uncheck it) and your device shoud have maximum light. Don't worry, it will go back to Auto when you leave the program (or whatever setting you had before you ran it).
Looks very nice and convenient especially for users who don't have flash on their devices; downloading now.
I needed this thanks!
does your tool set the backlight to the maximum or just fill the screen with a color?
Haha, very nice/funny app. Ive never used a cellphone as a flashlight. But hey, im gonna install this one. I like it

Just fills the screen. Quite honestly, I don't know how to change the backlight, but if you have any pointers I'll try.
Really useful for me
Would it be possible to use vertical dragging to change the flashing speed ?

Interesting idea. I can do that...
You need to find a way to disable the light sensor and adjust to the max brightness for this to work efficiently.
why i can not have white light without flashing? if i disable flashing i get a grey light
flashing OK, i choose red and white

Can you make it flash SOS it could be usefull in an emergency...
I think it is 3 short 3 long 3 short flashes...
There is also another flashlight app. It called 'pLamp'. Version 1.5 is compatible with VGA. Google for it. It's freeware. Works great on my diamond.

I realize that. Changing the backlight is not API implemented though as it is hardware dependent. I've been googling it for a couple of hours already and no luck yet.
so use registry?
to disable the light sensor
HKCU\ControlPanel\Backlight\LightDetectOn
set it to 0->Sensor is off (will change immediatly)
this should make it ways brighter
don't know which key adjusts the brightness level but you may set Battery-Brightness-level to max and enable Lightsensor. So if you now disable it, you have max brightness
works well for me, jsut implement it in your app and i'll be very happy
Update to v 1.1: added SOS function. Download in first post.

The problem with changing the registry is that it won't update the brightness until a soft reset, unless I'm mistaken.
yes yes yes turn backlight for max is more usefull then plenty of colours, btw 9 basic colours will be enough and still finger friendly... but still nice app

just try it yourself
after changing the key the sensor will be deactivated immediatly
no soft reset needed
and with the workaround I posted early you will get max brightness very easyly
but even without the workaround this will increase brightness massivly as the main usability of a flashlight is to enlightend darkness and the sensor dimms the display to minimum in darkness^^

HW Keyboard Backlight OFF when it's not needed (WORKING SOLUTION pls)

Hi All,
Xperia's hardware keyboard is very good, and the backlight is really of help when the ambient goes dark or even darker.
The HW keyboard is also quite cool in the daylight, the buttons' surface letters are very clear and crisp.
But here we have, an especial feature: needless automatic backlight, in spite of bright (or not so) day light? The letters become blurry not to say hardly visible. Not to mention this is wasting battery, too.
Is there a way to turn off the HW keyboard backlight, when it's not needed?
XDA gurus, help our batteries live longer and us users type faster! Please...
I hear you!
Yeah i've noticed the same problem, so ive started making a program to set the brightness etc, ive interrogated the registry for the backlight and have a small app working now whare all the brighness levels and timmings etc can be modified.
I was going to add a menu on the progam to changes the settings based on time of day / profile used on the phone, the rogram would need to be ran in the backgroud all the time but im sure it would not drain the battery much to do this as its a lightweight process that will wait for the profile to change.
I can put up what ive done, its very simple and you can suggest improvments / whatever.
Main functions would be:
allow user to change settings based on their currently selected sound profile (on, vibrate, off) and they have individual settings.
Allow the user to change all backlight related values (I have 11 of them editable in my program currently.
I would like this to have the keyboard light off during the day really as the keyboard light coming on makes it hard to see keys during the day.

Sounds promising! Can you post your app? I would like to try it out.
Here you go...
It just modifies timers and sensors on/off at the minute, but its a start. I made it to give better control over the backlight for myself, happy to help others!
Thanks Andrew! Longlive Ireland!

So Features
What do you want it to do?
look better? YES , lol!
i was going to use tab screen to seperate out the info, there are some more values to add that can be changed, i need to group them together (eg ac and battery ones) and have a proper explanation on them (input value limit etc.)
So let me know what are the features you would like (in order of priority) and i will get cracking, lets see if we can make a good little app here.
By now I only wanted the app to turn off keyboard completely. Hope the author will succeed in that. Though I'm afraid the HW keyboard backlight settings are hardware related issue solely, nothing to do with registry/driver routine.
All the other settings are quite handy to play with the backlight of the device. Perhaps a bit more detailed instructions and explanations will be just fine.
Yet the 'About' and 'Copyright' options, maybe some easter eggs - without it the prog is a no-go
Have you tried adding the key HKCU\Software\SonyEricsson\Illumination\QWERTYBrightness ? I found this one when digging into the illumination application.
This will override the automatic brightness values for the keyboard, setting it to a fixed brightness when the light sensor turns it on.
I've set mine to 50, which works fine even if the light goes on at daylight.
Thanks bro, this is very useful hint!
I noticed also, that with '50' (it's not 'key' actually, but a 'value', I input this as a REG_SZ value), light sensor works with HW keyboard much better, more adequate - no backlight when in sunlight or electric lamps at home or in office, slightly dimmer backlight when in the dark. That must save battery life too!

screen brightness

Is there any way to adjust the screen brightness beyond Settings/ All Settings / System / Power > Backlight tab?
The sun is shining and i want to see what is happening on my screen.
No, but there are some programs that allow this.
You can use the mvbacklight(it's a today plugin, search in the forum for this), or you can use wktask or AE Button Plus which both have this functionality.
I think there is another fullscreen program in the forum for backlight for that, but I don't remember its name.
Isn´t so. You must tap at the battery-icon in Startmenu, tap at the battery then opens the energymanagement. Disable the "adjust brightness automatically", so you see the brightness-sliders. Its so, because the Iolite has a lightsensor right from the StatusLED.
Greetings Mirko
Obviously my question wasn't clear enough. I am not looking for some program, unless.... .
My problem is that in direct sunlight i can hardly read what is written on the screen.
I want more light, more contrast.
The sliders in the menu Settings/ All Settings / System / Power / Backlight are already in the right corner.
Aha! Then its open end. Nothing solution to solve this. Must use a umbrella?

[App] NightStand 01-04-2010

NightStand is a simple alarm clock application with large numbers to be easily seen.
It allows for the phone to dim the screen but keeps it from turning off for that middle of the night glance to see what time it is.
Features Include:
Alarm with 8 sounds
Custom Color of the Digits
5 Minute Snooze Button
Solve an easy math problem to help you wake up (to you turn alarm off)
Automatically runs on AC power (optional)
Keep the device awake or let it go to sleep (optional)
12/24 Hour setting
How To Use:
When you run the application click on the configure button (upper right corner) to set all the settings
Three sliders allow you to set the custom color.
Alarm toggle to set the alarm and the sound.
AC Toggle to set Auto mode.
When the alarm is going off, click the snooze button to snooze or click anywhere on the screen to stop the alarm.
Update 1.1
The alarm should now go off regardless of what phase the phone is in (device awake or sleep), the app is running or not.
Screen is flipped
Update 1.2
Added an option to flip the screen
Update 1.2.1
Minor Update to start NightStand with correct orientation, Flip Screen option takes effect right away
Updated to work on HD2
Update 1.2.2
Fixed shifted screen on WVGA resolution (I think)
Added toggle for math question on exit
Phone stays awake while alarm is going off (for heavy sleepers like myself )
Looks nice.
A couple of issues on my TP2. The display is rotated the wrong way, and sliding the keyboard our causes it to get distorted. I'd prefer to use it with the keyboard out as I can tilt my phone .
I like it though, nice start.
P.S. let me know if you want the thread moving to the Development & Hacking apps forum from the Diamond one.
Dave
I just uploaded an updated version, try it out and let me know if it works better with the keyboard out.
Thanks
It crashes if you run the app with the keyboard out, and it is still upside down if I open the Keyboard after running the app.
Ta
Dave
it rotates correctly on my tp2, thanks just what i was looking for
Awesome work!I really like the big number.but,why not add a toggle button to turn off the backlight in the settings.I think it will waste lots of power when the device keeps dim.Perhaps you can add a sensor to lighten the lcd when we want to see what's the time now.
This Doesnt Work on my HTC HD2 even tho it suports WVGA Screens, WHY??
thanx.

does yours work when u slide open the keyboard and tilt it? i know i can use changescreen to change to rotation but it doesn't work with the keyboard open.
edit: i've jus hard reset and it works fine now even with keyboard open. Sorry for any inconvenience.
Same here, on my HD2 it's a nasty mix of colour. it needs something else to add?

same here, on my HD2 I've got only two color squares in the corners and one big rectangle in the middle... so no clock. settings and exit "square" button work well.
Not working on my HD2 either. Two boxes of colour on each side of the left hand side of the screen - one to change settings and one to exit plus a big box in the middle which is meant to be the digits i guess.
I got an error starting the program:
Can't find PInvoke DLL 'libgles_cm.dll'.
I got the same error on my omnia.
Can't find PInvoke DLL 'libgles_cm.dll'.
Please try to fix it. This is the program that I have been waiting for. Too Cool.

I got an error starting the program:
Can't find PInvoke DLL 'libgles_cm.dll'. (using HTC wm 6.1)
If you get the libgles_cm error i just uploaded a cab, give it a try
I got this error message when opening this program:
"MissingMethodException
This application requires a newer version of the Microsoft® .NET Compact Framework than the version installed on this device."
Please help.
you need .net 3.5
1.1 now has the correct orientation, but the display is messed up if I put the phone in Landscape and then open it.
Only a minor annoyance.
Dave
any way you could send me some screenshots so i can see if i can fix it..
Ok now working on my Omnia after installing 1.1 and the libgs cab you posted.
Two things.
First, if you have SPB Mobile Shell 3.0.1 installed, the app comes up but is shifted slightly. I believe this is because they do something with the top windows start bar. Not a huge deal but something I thought you could check into.
Secondly, Could you have a setting to determine which way to have the screen flip? I would like it 180 from where it is now. My power plug ends up on the bottom and so the phone won't sit level. If it was landscape but the other way, it would be perfect for the omnia.
Thanks,
Robb

(REQ) Backlight issues?

I generally have my backlight set pretty low for indoor purposes (20-30%) hopefully this conserves precious battery life.
However I find it mightily annoying when I'm on the move somewhere brighter than indoors eg. outdoors, and I have to check my phone and cannot see a thing because the backlight is set to "indoor settings" leaving me to navigate to settings> sound and display> backlight etc. This isn't usually a problem but when you can barely see the screen it is difficult.
Does anyone agree (hopefully a bright developer will) that it would great to have a backlight toggle on a quicklink within sense? I think a toggle between the setting you have manually selected and automatic adjustment of the backlight would be a handy application.
Any ideas? Does this already exist?
Nobody interested in this mod? Could save some battery
try myLight of mylostblog. google it. it's a very finger-friendly app that adjusts the backlight whenever you like but you have to set the auto-adjust backlight to off.
I have installed and it works well thanks for the link.
I would still like to see a toggle option between automatic and a preset value.
I would also like a toggle button or buttons for different settings (30%, 60%, 100% or customisable). Another idea would be for the auto backlight to work better. I had a Diamond and it was problematic with that. Not bad for most of the time in UK but if the sun comes out it's almost impossible to see what is on the screen. I might look at a mortscript solution using the reg key for now if I get a chance.
Yea I reckon that would be great. I think the HTC desire has this sort of toggle option in a status bar. To take the idea even further, it would be nice to see this sort of bar added to Cookies Home tab, similar to the new notifications bar added to v1.7.
Possibly: Wifi, backlight, bluetooth, 3g/2g connection all in one bar.
Im trialling MyLight now and it works well, it is finger friend and can be added to a quicklink for easy access, but looks a little dated perhaps.
