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.

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

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!
I want to ask you something. On direct sunlight the display light is not enough, when I manually set it to 100% the display is much more bright and everything is ok, but when is AUTO, it wont go to maximum never! I'm asking is there any tweak for this, or anyone who knows how, to be kind to make something about this.
Hey - there's a couple of programs that can manage the light sensor instead of the default built in one.
First i used lumos however i found it wasn't that customisable. Yesterday i found a program called AutoLight which works by adjusting a graph to how you want the backlight to change according to the ambient light. Works really well so far!
Just search for them on here and they'll come up.
I have noticed that the Automatic control for the backlight on the HD2 works very well. I have never feel like the phone is too dim and only in the darkest rooms do I find it to be a little too bright.
The Auto backlight does not seem to have the ability to get down the the lowest backlight level of the HD2 screen. If I turn off the auto function the screen can get to that "barely on" setting, but on auto the lowest is seems to go is to around 30%, which can be bright in the car at night or reading in bed.
Is there a way to make it so that the automatic backlight control can go all the way to the lowest setting when appropriate?
Have you looked into using 'lumos'? You can find it in the HD2 apps forum section.
I used it before and it should work for you to get the lowest backlight. I stopped using it since I figure 30% is good enough for me in most situations. During my commute, the light sensor gets hit too much and the backlights changes too often so I just turned it off. (I think it may also save me some power as well.)
If I'm reading in the dark I manually set it to 10% and in the morning I set it back to 30%. It's not too often that I will read in the dark so it's not a major issue for me.
I guess along the same lines, is there some app or widget that can be called from the home-screen icons that can control brightness on the fly?
Sense's brightness control is hidden behind far too many presses to make it comfortable to switch quickly. It's a bit annoying when I'm checking my e-mail at work walking under a set of lights, the screen will dim, then brighten, then dim, then... every two steps. Jumping to the menu to change the settings is too cumbersome, something along the lines of two clicks would be much better.
use Lumos
I had the same problem, Lumos works very well in the HD2.
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?
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.
