Backlight too bright at night - HD2 General

At night the backlight too bright when set to Automatic - it won't go below 30% even when it is totally dark. It seems like this threshold can't be changed. As a workaround, does anyone know if there is a way to make a shortcut to the Backlight settings screen that can be used in Quicklinks, so at least it can be quickly set manually.

try lumos. it works on the hd2

Backlight/Screen Brightness - Auto Dim and Auto Off

Has anyone seen an app that dims the backlight before it turns off all the way ?
When I had my 6700, I had discovered that the OS (and I am sure on the Mogul too) was only using some, not all of the power states. I will have to play around with it, but I used one state to leave the display on, without backlight before it went into sleep mode. I also setup the wav device to be on in sleep mode to improve the ring speed.
Will have to poke around to see if you can just dim the screen...
The state that I was playing with was called UserIdle and can be found in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts
MSDN has good documentation on the power states...

This probably does not give you what you want, however this will dim the screen (although too dim in my opinion - I have not been able to change the brightness)
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\UserIdle]
"bkl1:"=dword:00000003
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\UserIdle\{EB91C7C9-8BF6-4a2d-9AB8-69724EED97D1}]
@=dword:00000000
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts]
"ACUserIdle"=dword:000000B4
"BattUserIdle"=dword:000000B4
Make sure that your display timeout/power timeouts in the control panel are set greater that the ACUserIdle/BattUserIdle otherwise they will occur before the backlight can be put in its dimmest state.

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.

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

Auto Backlight level

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.

Auto or manual brightness..that is the question

I have been experimenting with brightness on my sgs and how it relates to battery life. So should I keep the brightness on auto or the lowest?
I have noticed that when my brightness is set on lowest, the phone will sometime turn the brightness up a lot for no reason. I think it should be on auto brightness.
Ideas?
on the notification bar up there if you sweep it left our right it'll adjust the brightness too, just found that or. pretty damned annoying.
my brightness is on it's lowest always, unless I need to see in the sun.

Yeah.. In Froyo they don't have that "feature" (hopefully they don't enable it either).
I keep my light down to minimum too. I've had no probs looking at the screen here, but then again, it is winter and I am an evening person..
I'd say lowest setting is the best, the screen isn't difficult to see even at it's lowest. brightest just makes everything look more vibrant and awesome. you can have a separate brightness setting for the browser too.
i set mine to manual
the auto doesn't work well, i like it bright, and in auto mode, it is not bright enough for me

You are right. If you have your brightness set to Manual, you can adjust brightness by sliding left or right on the notification bar at the top.
It's a problem because you can by accident set it to high and therefore drain your battery fast.
I have setup Tasker to set brightness to 40 once every hour. 40 is about 16% of full brightness.

Alliance rom screen dimming issue

Running the Alliance rom, clean install on stock slot. No other major issues that I can think of. I've got it set to maximum brightness, not on auto dimmer. When the screen dims after 30 seconds or so, when its about to turn off due to inactivity, half the time when I tap the screen, it recovers to full brightness. The other half the time, it gets a little brighter than the dim mode, but not much. It stays way dimmer than the full brightness setting that I keep it on. I have to pull the notification bar down, slide the dimmer down, and back up to maximum, and I'm good to go until the next time it does it. Which could be in 30 seconds when it dims again.
Anybody else having this issue?

I have the same thing happening. Personally I have been too lazy about it to check through settings to see if I've done something. I'll check on it and see if I can find a fix.
*Update*
I've checked through all my settings and can find nothing that might cause it. I don't have Auto Brightness set, nor do I have Auto Adjust Screen Tone turned on. I saw nothing in the Alliance Settings either. I believe it is a system setting that is probably buried in code somewhere (far beyond my knowledge).
**Update** I reported the bug in the Alliance Forum.
I tend to agree. I've looked through settings, etc. just as you have, to no avail. I'm nearly certain it's done it since install, so I don't think it's something that I've changed. But I could be wrong. I've also tried it with auto adjust turned on, does the same thing. Auto adjusts to a dimmer setting sometimes
