Registry fix for Universal keyboard backlight duration?

Does anybody know of a way of extending the Universal's keyboard backlight duration longer than the highest option of 10 secs? My eyes are hurting trying to see the keyboard at night. :shock:
Don't want it a lot. Maybe 20 or 30 seconds? Perhaps this is a registry setting?
TIA

Dont even need to change a registry setting mate
Go to Start > Settings > Buttons
Then click on the Backlight tab, it brings up the options here to either have the light sensor enabled or disabled, and also how long you want your keyboard backlight on for

Sorry
read ur post wrong
Only realised myself the highest option is 10 secs!
Doh!

Yes, there is a registry setting...
HKCU\ControlPanel\Backlight\QKeyLedTimeout
Change it from 10 to whatever you want. I originally set it to 60, but found that was way too long. I've got it set at 30 right now and that seems to be working well for me.
You need to soft reset after making the change before it will go into effect. Remember to turn the device off before you soft reset to make sure the cache is flushed and your change is saved.
HTH,

What about a way to change the sensitivity of the keyboard light sensor? We all I think find it not sensitive enough, and when it's too dark to see the keys, it still doesn't come on.

My light sensor does not work, I thought it was a firmware glitch !! does your keyboard light sensor work ??????????
O2 XDA Exec UK

In what way doesn't it work? Are the keyboard lights always on or always off? At night, in the dark, do the keyboard lights come on when you press a key? Have you got the ambient light sensor enabled in the Control Panel?

I thought my light sensor wasn't working either when I first got it, not realising that you had to tap a key before it would light up.
I was also one of those that didn't know where the stylus from the box went (it was the spare)

Thanks for your reply, I have since hard reset and gone for corporate mode, and it has started working originaly in a pitch black room no matter what key I pressed, it refused to light up.

Automatic screen brightness using camera or Light meter

it is possible ?
I'm using the KAISER, when in a building i set the brightness to low becuase it has a very bright screen and it's just a waste of battery
But when i go outside i can't see a thing, need to set it to high again
And then i just forget to set it to low again
is it possible to make it be automatic ?
(bright outside - high brightness, dark outside - low brightness)
Thanks !
p.s.
does the KAISER have a light sensor like the Universal's keyboard light sensor ?
if so, is it possible to use that ?

ah man i hear you. when my sister got her blackberry pearl, and i saw it automatically change brightness, i was jealous. aha. unfortunately, the sensor is hardware thing.
i'm not sure about the kaiser but i know the hermes has a keyboard light sensor, but it's on the keyboard, and only says whether to turn on the keyboard backlight or not. not too useful, i'd think.

Hermes and Kaiser have front cameras...

but camera is a no-no for battery

Even once a minute, or on power-on?
Well, maybe yes.

I nice Solution would be a Button you press it, and the Brightness gets configurated automaticly: perfect for battery because you do this only on need!
And there could be a standart brightness reseted after having standby on
I dont know how to use the Camera in VB.Net someone knows?

I was thinking more in the direction of the front camera and the timer ....but bettery above all .... if it is possible it would be awsome !
the buton pressing idea is (forgive me) pointless ... if i wanted to press a button i might as well press the on screen button i already have ! (spb mobile shell)
thanks for the idea though !
it's great to see so many people taking interest, hope it will stick !

SPB software is my solution. You can map your jog dialer for brightness. I use that for volume, so I use touch screen to slide my brightness.
http://www.spbsoftwarehouse.com/products/pocketplus/?en
look at the screenshot or demo. Map the brightness as botton4 is a option because brightness is a program link for you to set what ever button as you wish.

blah, i have an at&t 8525, so i forgot about the front facing camera. my current solution is to set the backlight to reasonable indoor setting, and i have VJLumos mapped to my Button5 press&hold. so whenever i go outside, I run VJLumos, and when I get back inside, I run VJLumos again (which turns it off) and it automatically goes back to the previous backlight setting.

how to set dimmer of the backlight

Hello
thanks for help
in my previous kaiser , after 30 second the screen backlight dim (don't shut down, set to minimal position) and after 1 mnute the kaiser completly go on stanby
this is all ok
But in my new P6500
after 30secondes the back light completly switch off !! but the p6500 still wake, and after 1 minutes it goes to standby
How can i set or make some regsitry tweak to make P6500 go to dim backlight after the preset time just like kaiser ??
Thanks

The Sedna screen is different from the one on your Kaiser , you can read whats on the screen even when the backlight is completely off.

Well, assuming there is sufficient ambient light! In total or near-total darkness, I would be VERY surprised if it still could be read.

In near-total darkness you definitely can't read whats on the screen but you can read it when the backlight is off and you are holding the pda under direct sunlight .

Automatic Light Adjustment

I've just bought a Touch 3G and as far as I can tell the Auto setting for the Backlight doesn't seem to do anything. As my last phone (P3300) didn't have this, what should I be expecting to happen? I've tried putting a finger over what I think is the sensor (right hand "LED", beside speaker) and nothing changes.
Thanks, W.

Did you set Auto adjust backlight in system menu?

Imho it is a really subtle effect. You can see it a bit when holding the light sensor (right to the speaker) to a bright light source. The display then gets a little bit brighter.
If you would like to increase the effect or customize the stepping, try g-light ( http://www.ageye.de/index.php?s=glight/about ), it lets you set specific values for each reported value from the sensor, and set the polling interval

Jade auto adjust is poor
I had the diamond prior to purchasing the jade. The diamond auto light adjust was very noticeable compared to the jade. In fact I didn't think the Jade even had a light sensor until one of the other users pointed it out.
After a little research I found this thread. http://forum.xda-developers.com/showthread.php?t=450318
I used it on my Jade and it works great. One of my problems with the diamond was the fact that the light would not automatically dim enough in low light conditions.

Thanks for the link. Now using G-Light which works pretty well. Not perfect as its sometimes a bit erratic but certainly makes better use of the light-sensor than HTC!

Automatic backlight broken or just badly designed?

As far as the automatic backlight setting goes, it is my understanding that the phone should check how bright (or dark) it is, and adjust the display brightness accordingly (brighter when out in the sun, darker when sitting indoors / dark rooms).
However, it seems to me it just sets the backlight at ~40% and that's it. I went out into the sun with my HD2, and the brightness didn't change and I had trouble seeing what was on the screen.
Is there some kind of way I could test, if the light sensor is working? Or is this setting simply badly designed and I should set the brightness myself?
I'm currently running latest Energy ROM (23569 Cookie May 09) but it was the same with the stock ROM, so I don't think it's related.
PS. A little side question, if I may; if I perform task 29 before flashing... do I still need to do a hard reset after flashing a new ROM?

...in the very least... are there any apps that make use of the light sensor?

Well I know the acctualy percentage in the settings never changes when its on auto (atleast not for me)
But I can clearly tell a difference between being in a dark room and the backlight being on low
to being in the sun and it on max.
Ive also never had trouble reading the screen, the screen is always plenty bright enough.
Prehaps you've got a bad one?

I know an app that can measure the amount of light in lumers.

Care to share the name of that app?
Also, it's difficult for me to say if the screen is busted or not. On max brightness (as opposed to the automatic setting) it's a lot more comfortable to look at in the sun, albeit indoors it's OK on any setting really.
EDIT: I don't suppose the automatic setting can be tweaked for better performance via some registry changes?

I think it's called Lumos.
Try searching for it.

You certainly can test it. Just cover the light sensor (upper left corner above the screen) with something. I don't recommend thumb, as you might press 'start' button. You will also need any application with white background.
The brightness should clearly drop.
Auto only sets the brightness from 20% to 60% (or so it seems). But the effect is clearly visible.

No change at all.
I'll restore the stock ROM to see if it's a firmware issue, and I'll check that Lumos application.
EDIT: Lumos clearly detects light changes and works well. Seems it's either something to do with Energy ROM after all or possibly I'm just blind and I can't see any changes. I'm still going to check the stock ROM, just to be safe.
BTW, once more, can someone tell me quickly if hard resets are needed after task 29?
EDIT 2: OK, it DOES work after all, I'm just blind; the change however, on the automatic settings, is minimal. I actually had to put the phone under a light-bulb, as covering the sensor didn't really work. I wonder if it should be calibrated like the g-sensor...

night time
i think the day time brightness is fine but the night time setting is far to bright. i would love for this to be customizable as well

Can this range be increased?
For indoor use the auto-adjust works fine for day/evening/night, but outside I always need to turn off the auto-adjust, so it can go to 100%. When back indoor again, then switch to auto again and so on ... and so on ... and ...

Just installed .NET CF + Lumos and will see how it works out.
