who knows how to turn off the light sensor? should that be always at maximum
Is it that thing that make my screen going dark sometimes and then bright again ?
I thought it was a bug in Android about the screen light management...
I'm very interested in turning it off me too.
I didn't look very hard, but from what I can see, you can't.

Yes, it does just that hinders and tired eyes!
The above sentence makes absolutely no sense.
sorry,I mean ,that light sensor kills my eyes
Still it makes no sense at all!

Ok guys, we all agree that his english is horrible, but it is understandable that he is saying that the changing / blinking of light, all the time, is not confortable for eyes.
I admit... for once, I understand his words...

Turn the brightness down if it is uncomfortable? The reason why it changes automatically is to adjust to the amount of light in a given place. Otherwise, you'd have to constantly change the brightness yourself in order for the screen to be visible in all conditions.
Yes, I think we all know what is that function for, that's not the point.
The problem is that, in the same place with the same light, if, for example, your head make a shadow over or if you put your finger on the little hole up right the phone, the light of the screen will change as if you where in a place darker.
So according how you move the phone or hold it, your eyes will have to accomodate very often and it's very uncomfortable.
Maybe covering permanently that little hole will be the solution... but I would prefer just to turn it off.
Covering it permanently will also permanently place the backlight in the darkest mode. Personally I like this feature, once you know it's there it doesn't give a 'wth is happening'-feeling anymore and I believe it saves battery (no need for full brightness in dark places). Also for me it kinda gives that viewing-on-paper feeling, the device is quite okay in maintaining a balance between minimum visibility and overlighted eye-blasting power
Though yes an off-feature would be welcome sometimes ^_^
I would also Love to Disable this sensor.. More Brightness! MORE more more i tell ya! lol

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:

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.

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.
When I have my nexus one set to automatically adjust brightness, it doesn't seem to do anything.
I can move it between dark and bright environments and the screen brightness doesn't seem to change at all. Am I missing something or is this feature not working on my phone?
It works fine with mine. I just clicked auto in the brightness setting. Make sure you didn't accidentally change it to a different setting with the settings widget that is by default on the first home page to the right.
works fine on mine yet not a feature i use....i just set it statically.
I find the auto-brightness to be too dim for my liking. It would be great if you could adjust the overall brightness while still maintaining the automatic scaling.
Turns out it does work, it just need to be *really* bright to make it change.
It doesn't change really at all in my office between switching the lights on and off (even though that's a really big change in light levels to me). However, if i go outside, it does get brighter.
As you say though, it does seem to be set a bit low (hence it not brightening up when my office lights are turned on I guess).
If I enable auto-brightness on mine, it seems to constantly vary the brightness in my office. It's annoying as crap and I turned it off. Am I the only one?
It's probably taking a look at the available APIs to see if it's easy to write a quick app to do auto brightness with settings to be able to tweak it.
The auto-brightness feature changes constantly for me as well.
I 'm also having issues of the varying brightness when using auto-brightness -- even though the lighting in my environment has not changed and I avoid contact with the light sensor. It's VERY annoying.
I've since switched to using a static setting for the brightness.
auto brightness was one of the first things i turned off. it was way too dim for me
Not bright enough for me. Doesnt seem to change much.
I do see the variability occasionally. Most of the time it's stable, but it will take spells of shifting up and down repeatedly. Glad to know I'm not alone.
Auto bright annoyed me as well when I first got the phone. Then I realized where the sensor is (top left) and what it was responding to. Depending on where I'm sitting, what light sources are behind me, in front of me but reflecting off of me. It's usually just responding to a light source that's just withing view of its sensor. Also, my hand has shielded the sensor more than just a few times, confusing the sensor.
Now I leave auto bright on all the time, and it more often than not does a good job.
IMHO this is one of the few broken features on the phone. In continuous lighting it jumps from bright to dim to everything in between like a jack rabbit on speed. I still use it to save battery life but it pisses me off regularly.
am also having this problem. it constantly goes much brighter, and then, suddenly goes back to dim.. very annoying... however, the light sensor for calling works well... so, is it a software issue.. hope it gets google's attention and gets fixed in next update...

+1 so I also manually go between three on the widget
Note that the light sensor is under the glass on the front of the phone. Some cover-all cases cover this, and if you use one of these I assume your phone will remain on the dimmest setting.
In general, while indoors it will remain on the dimmest setting (for me anyway), but rise to the necessary full brightness when in sunlight.

There are two sensors, one is a light sensor and the other is a proximity sensor to detect when you've taken the phone from your ear. I think you're referring to the second.

+1 constant occiliation on dimmness levles under consistant light. It goes from way too dim, to just right then back dark again. I too hope that google will correct this with the next update. Hopefully the patch gets pushed soon, i'd like that extra memory
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?

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.

I really like the auto brightness feature, but it's consistently too bright for my taste.
Is there a mod or tweak out there that will allow me to lower/adjust my automatic brightness levels to save some battery life?
(Currently running Blackhole 3.0 / DL09, will go to Blackhole 4.0 once it's out tomorrow)
anybody have any ideas
Unless you know how to modify the kernel source (which I believe is written in C, correct me if I'm wrong devs) or modify some file that is the delegate for the ambient light sensor, you're SOL buddy.
Its probably hardwired into the kernel, would be my guess.
Hmmm, I thought automatic meant automatic. My bad. J/K

Yes, automatically too bright in most situations. Yet not bright enough in sunlight.
I almost need to cover the light sensor some to fool it.
This is where Samsung fumbles. Their software is poor. Whomever is writing the code, set the light sensor to brightness conversion wrong. At least on DL30 they fixed one mess up. On the original rom, when you plugged in external power, the brightness would go to a fixxed level. If you were outside in a car and plug in power, it would dim the display. Indoors at night, plug in power, and it would BRIGHTEN the display. What's up with that.

What's the purpose of having a light sensor if it never works?
Often when I pop my phone open to do a specific task, '5 seconds' is about as long as it would have taken to do that whole task. And it's just annoying to unlock the screen, begin to attempt doing something, and then notice 'oh hey, the screen is basically unseeable!' and have to interrupt whatever you're doing. Or, even worse, when you're going from place to place and go through areas that are lighter and darker, forcing you to keep interrupting your work.

You guys nailed it. The screen is far brighter than I need while indoors at the office, but step outside and it just doesn't keep up with the bright Colorado sun (I can adjust it manually to a level that can be seen in sunlight just fine).
I could spend 5 secs adjusting the backlight each time the light environment changes, but why not spend 30 min optimizing the auto brightness levels and then never have to worry about it...
I know with my Moto Droid, someone had made a code that altered a particular file to change the lowest brightness level, but I have yet to see that for the Fascinate. It's a shame since the Fascinate's screen is so much nicer, but not set up optimally.
I know some dev's had also integrated the ability to change the auto brightness levels within custom ROMs for the Moto Droid. That'd be a great feature on the Fascinate!

That is to peoples own preference. I use auto most of the time and its fine. Doesn't work would indicate it doesn't change the brightness at all.
You can't expect it to auto sense it to every persons liking. Also does power control change it so you can see the screen, cause that doesn't take '5 seconds'

Try Screen Filter - its in the app store. With screen filter applied I keep my phone set to auto and screen filter reduces that more - in my case 50% more.
Well in the DL30 rom you don't have to go to the settings menu to change the brightness, just press and hold on the notification bar and then slide left and right to change the brightness.

Anyone else noticed the button Backlight brightness being very low?
It's like a dark blue light and I almost can't see it.
Also the Touchscreen doesn't react sometimes while scrolling. For example while seeking trough files in a file manager it stops sometime instead of scrolling further while swiping.

I can't see any buttonlight at cloudy daylight. This makes it pretty useless. If there were visible dots at daylight, the light would be usefull for night use but as I said you can't notice any dots at daylight
The big problem is the RGB led luminosity. It's like the button backlight, but it is useless if i can't see it...
The odd thing, or I guess another observation in general...is that I have rarely had "misses" with the back or recent buttons. It seems like they made the touch area much much bigger than just around that dot. So, although this is annoying, the actual effect it's having is minimal to me.
Yes, I was tempted to find a transparency to stick on the top just for effect I do sometimes hit the "Reply" icon in Outlook messaging when I mean to hit the back button below it.
It would be nicer if the blue light was a lot brighter. Maybe a firmware update?

What I don't get is why OnePlus just didn't give an option to always keep the capacitive buttons lit permanently, or at least increase their timeout period. With all the other ways you can customize Oxygen OS, this seems like an odd miss. Samsungs have had that option forever.

As mentioned in another thread about this, there is an app called Keyboard Backlight Controller. I have it so they stay on when the screen is on. You have to disable and enable after each boot but it's not awful. It's better than nothing. In sunlight though, you can't see it at all.
