Automatic Light Adjustment - Touch 3G General

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!

2 Tytn Questions

Hi All,
Got, (Finally) my Tytn 3 days ago.
2 quick questions, (that might sound stupid to some of you.... )
1. is there a key-light on the QWERTY keyboard?
2. when I'm outdoors, (sun light) the screen is almost unreadable....
Any suggestions?
Thanks
1) yes.
2) increase backlight

so how do I turn the keyboard light on?
The brightness is set to MAX......
10x
the keyboard light turns on automatically when the room brightness is not enough (there's a light sensor between the "P" key and the green phone key)
For screen backlight.. I don't know.. mine works well even in high sunlight (when set to maximum brightness) however there's a tool from vj that increases backlight over the maximum value (like when you start the "camera mode") but as far as I know it can be used for small amounts of time (if you don't want to damage your device)
http://www.vijay555.com/?Releases:VJLumos
VJ has an app that will allow the screen to overbright like it does for the camera. It is in the latest WM6 rom. its called BrightScreen.
This helps a little in really sunny places but I also find the screen hard to read outdoors.
The Keyboard has an auto sensor that should activate it only in low light conditions. Change this setting under Settings > Buttons > Backlight Tab

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.

Possibility of Auto-Change Backlight ???

Hey guys,
do you think it's possible to wirte a program which automatically can change the backlight according to the actual daylight condition.
Maybe it is possible to start the program when you wake up your device. then the program turns on the built in (front) camera for about a second or maybe more. The camera "checks" out the light intensity. If its very bright the backlight condition is set to the max.
his is only a idea. I'm thinking of it because for example today it's a very sunny and i can almost read nothing on the display of my touch cruise!!
What do you think about it?
greetings
any idea?
Or does any software like this exist?
Maybe the guy who wrote this program below could be of assistance:
http://forum.xda-developers.com/showthread.php?t=379270
Well, it doesn't have to be so hard...
All we need is a small service that reads from a file the approximate sunrise-sunset time and alters the brightness accordingly. If anyone has the time, he can additionally take advantage of the current time zone and calculate those limits automatically all year long!
Destinator 7 does the exact same think by turning night colors on and off. It is actually better than a build in brightness sensor because it never fails!
Nevermind...did not read the question thououghly
Yeah good ideas,
but a time sceduled scenery has also disadvanteges. When its clowdy outside it causes unnecessary battery consumption.
MVBklight 1.4.2 is not working on my polaris!!

I come from a rather sunny country (greece) so I really missed this!
Anyway, those PDAs have actually very low brightness screens. In a bright day you cant actually see anything. On the other hand, I have yet to see a rainy/cloudy day that requires a reduction to the maximum brightness level. Overall I think that a time scheduled solution should be the best solution for no sensor-equipped devices.

I second that! Even though I'm not from Greece but it's never too bright during the day. Right now my solution is to map the camera button to backlight so I can change it quickly.
Changing the brightness according to the time of day would not be as helpful as changing it according to the ambient light level. If you walk inside a dimly lit building during the day, you don't need the backlight to be as bright as if you were outside. Also, even outside, a cloudy day can be considerably dimmer than a sunny day.

I totally agree, but given the fact that there is no ambient light sensor in our devices I dont think that we can do any better. Two scales, one for day and one for night and we are OK for most cases. Yes, as you point out this strategy fails but it is better than:
1. No brightness change at all
2. Manual changes.

Thats the crux. Some devices especially the newer ones have a camera on the front. I'm no photo-expert but i think every camera is a "ambient light sensor".
The camera also reacts on different light conditions. You can see this by turning on the fps function. But i agree that it would be a lot of work.
Maybe we have to wait till more people and programmers own htcs with such bad displays like the polaris.
Titan Photo Sensor
I found myself thinking about this auto-backlight topic on my way home tonight after a long trip using my 8600 as a GPS. The screen went from being a clearly-visible screen during the day portion of the trip to a flashlight in my eyes at night. While I knew I could adjust the backlighting manually, I didn't want to mess with it while driving. Also, living in Arizona, I can barely make out the screen when in daylight unless the screen is on maximum brightness, but max brightness is horrible on battery life, so I would rather not set it to that by default.
Anyway, the Titan has a photo sensor on the keyboard which is used to determine dim lighting conditions and automatically illuminate the keyboard. I'm not sure if the exact lighting value being detected by the photo sensor can be read, but if it can be, then it should be relatively easy to write an application that would automatically adjust the backlight setting whenever the keyboard is slid open.
The application could both use location-based sunrise/sunset algorithms to set the default backlight value based on time of day, and also allow the setting to be overridden momentarily (perhaps only until the screen is turned off again) by opening the keyboard and sampling the ambient lighting conditions.

How to decrease backlight while keeping auto adjust?

Hi!
I wonder if there is a way to lower the backlight levels on auto adjust (or increase for those who think its still not bright enough). Point is I think having the backlight on generally lower levels will naturally increase battery life. I know I can change the the brightness to a fixed level that suits me - but that would just be right for the current situation. I still want it to adjust to different lighting situations. Ideas?
It would be nice if it was possible to change how dim the backlight gets on total darkness and how bright it gets on your average sunny day.
I've been messing around with the reg to see if I could find max and min values but I can only change manual settings, not auto mode using the light sensor.
One note though: The sensor itself uses battery to measure ambient light. That being said, if you spend most of the day under a constant light source (say an office) manually dimming the device should consume less energy since the sensor is not doing much good for you anyway.
I guess it's not your case. I had this app on my Cruise to change backlight intensity. never used until now. it works on leo (running 1.48 but that should not matter) and changes backlight in 25% increments. You can copy a shortcut to the startmenu and add a quick link to your home tab or map it to a hard or soft button somehow.
I wold really like to know how to change max and min levels on auto backlight.
Try Lumos - it's a backlight replacement that allows you to customise how you want your auto backlight to work, ie. what the minimum/maximum brightness is, how fast the backlight changes, etc.
http://forum.xda-developers.com/showthread.php?t=450318
Seems to work fine. Still some tunning to do. Thanks!
I'm using Lumos now and it works great! Simple to set up and easy to customize. Thanks for the hint!
lumos is great but I found it was draining the battery quite fast on the leo.
Admittedly I was using it with the wm6.5 Check for active programme only setting. I never tested it to see if it worked without checking that box.
As far as I can tell by now the batterylife appears to be rather better than before. I haven't put in any application exceptions and didn't check the one checkbox in the settings tab. I also use a custom curve where the backlight stays at 30% until the sensor hits about 400 (30% is plenty in my opinion and still brighter than my friend's iphone in normal light condition inside).
you should try AutoLight http://forum.xda-developers.com/showthread.php?t=548402
it works fine on Leo

outdoor backlight increase

Htc Hd2 has only one flaw: outdoor display contrast. in the bright day contrast is not on the iphone display level.... if there is a possibility to increase display light and contrast?? i try lumos but result is same as before... I dont want to use antireflect foil or anything similar ....
I suppose that's very subjective. I use lumos with my own settings for the brightness curve (linear with a deep slope) and I can use it in daylight with no big issues.
In case you wanted to test, you probably could set the screen brightness to 100% manually from manila preferences to see if that suits your need, and then agjust lumos curve to your needs
I try again with lumos .... probably something I was not well set up ...
hey! -------> this time it's better and brighter!
But isn't the auto-backlight feature doing the same thing? Making Backlight bright when outdoors?
How is it compared to lumos?

Lumos gives you control over the backlight. You can set up minimum and maximum backlight as well as the backlight intensity curve (vs external light intensity).
The built in auto backlight feature is very weak. It is fine for indoor use but it does not seem to get any darker in the pitch black and does not get much brighter in direct sunlight.
I find myself manually adjusting it everytime...
Agree - the automatic backlight is not working sufficiently. You all need to log this with HTC customer support so they can add it to the next firmware release. Issues really need to be logged sooner rather than later as this phone is going to soon be too old to warrant HTC spending any more time fixing things.
I've been trying to report everything I can before windows 7 comes out and everyone forgets about the Leo.
Hm, well I recognized that the Auto-Backlight is sometimes "slow". But not always. If I walk from a bright room into a dark room the display gets darker. But sometimes it stays quite bright.
Perhaps I give lumos a try. At least to compare.
But when Lumos has so many options to set a brightnes curve, won't you find yourself setting up an adjusted brighnness curve everytime because there is no curve that fits to every situation?
Sometimes there is bright sunlight and shadowy corners, sometimes there is a thunder-storm and barely light.
The light gradient won't be a linear one .
Ok, I played around a little bit.
What are your Max values with HD2? 1178 at mine.
0 is Min value but thats clear. Only thing that is wierd: When I move to a place not directly near a lightbulb the sensor goes very fast down to zero.
It shows zero but it is not dark in the room at all.
Is it the same at yours?
