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.
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
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 ...

Even on the dimmest settings, the Vibrant is too bright for me in bed, where the light disturbs my wife.
It seems that, with root, you can lower the brightness further - at least on other phones. Is there any way to do this with the Vibrant?
Thanks!
The "Dimmer" app will toggle it from your current brightness down to 10 but if you find something that will go lower let me know.
It has an automatic brightness control based on input from the sensor. You may need to disable this in the settings too, but I would think it would be automatically dimming itself already in a dark room.

Right, but that doesn't get dim enough in some situations and the minimum brightness you can select manually is 30. "Dimmer" will take it all the way to 10 but I would like to see something that would take it to 1 or 2.
I agree. It's too bright in low light situations.
If you find a solution please post it.
Try the Screen Filter App from the market. You can get UNBELIEVABLY low brightness. Which means much better battery.
+1 on screen filter. New version now dims taskbar too.
I really love this new Always On Display (AOD) feature, it's really classy and elegant.
But, one thing I noticed is that the brightness level seems to be automatically adjusted, and when its bright it surely drains the battery.
Is there anyway to set this brightness manually? I tried changing the display brightness in manual mode, but it does not seem to use that settings.
Any suggestions would be much appreciated.
I dont think there is an option, if there is i am also interested.
I personally thought the Display sometimes was too bright.
i..e In a Dark Room and the Light was more ambient than it really needed to be.
Then the misses would ask me to turn off the night light lol!
Always On
Dear All, I just bought my S7 Edge and picked it up yesterday. I'm quite impressed with this display!
I thought the same thing you guys tought... The Always On Display is very bright!
But here is some info that I searched over the internet. Don't know about it's reliability, but seems legit.
New Always On Display
An interesting function that first appeared on the Galaxy Note 4 Edge in 2014 was always keeping a portion of the OLED screen on when the phone is off (in standby), so certain content can be displayed all day and all night long, but with a very small power drain that has very little effect on the battery running time. This is possible on an OLED display with a mostly black background because every sub-pixel is independently powered, so black pixels and sub-pixels don’t use any power.
The new Always On Display mode shows various personalized clock, calendar, status messages, notifications, and images on the main screen when the phone is on standby. It measures the ambient light level and has both day and night modes, plus it’s smart enough to stay off when the phone display is face down, or it senses a dark confined space such as a pocket or handbag. The OLED display produces an illuminated main screen image 24 hours a day so you can always discreetly check it with just a glance. As a result, the OLED Always On Display will reduce the need for a smartwatch, which seems likely to become an endangered species. We’ll cover this in more detail below.
Here is where I picked it up. Cheers Guys!
(Received a message with the information that I can't post url's.. ) sorry...
Type this in google, "always on display s7 edge brightnes" then it is the 3rd link in the url contains displaymate
same, it quite bright, and with my testing if you can keep ut at its lowest brightness, it consumes 0.3%/hr. that would be absolutely great.
there is an app always on display plus which helps in that
if you mark on auto brightness , it will be done
I unmarked Auto Brightness and seems not brights
Hello guys did anyone find a solution to this?

I've noticed that it is automatically adjusting by the amount of light in the room (and it's quite sensitive, always brighter than needed). It would be great if there was an option to manually set the brightness, but only small bunch of people are actually interested in this.

This app does not changing the actual brightens, seams to be there is no solution yet.
I tried changing the screen brightness to minimum and disabling auto brightness, but the AoD brightness seems to be controlled independently.
Trying out an app called Always On AMOLED - it has a night mode. Gonna test power consumption of both
Mine used to auto adjust but not anymore. I think the last software update changed this.
GS7
I'd love to have an adjustment setting. I'm having the opposite problem as most. Mine isn't bright enough! Oh well. Hope they change that!
AOD brightness fix for Galaxy S9 and S9 Plus. May fix others
This may not help everyone as I am giving you the solution for the S9 and S9 Plus, but look in your settings to see if you have the same thing.
Under 'Lock Screen and Security' select AOD and select 'Show Always'. Once you've selected the Content to Show, disable Auto Brightness then move the slider as far right as possible and underneath that select Show Always.
Job done. Next time you see your AOD it'll be full brightness. It is still not bright enough but better than before. If you then go into 'Clock Style' and change the colour after type and choose a fairly stand out colour, this will make your clock stand out even more.
I hope I've helped at least a few people.

i feel like its to bright... i want to dim it. dont need it to be that clear.... i wil continue my search....
Threw search and having both s7 and s9+ I noticed the 9+ has the ability to adjust the brightness of the AOD very easily in settings or double tap the screen and u see the settings. Works perfect on the 9+ as for the s7 doesnt have the same settings they both say the latest version available is downloaded but it's an s7.. so I just think that setting dont exist on the s7. The brightness is controlled on it's own and u really have no control manually on the brightness.. I think it's a new thing for new galaxies but the 7 isnt gonna do it.. eh.. so I suggest a contrast color which makes it "brighter" to the eye. And basic and big.. it's for quick glances anyways... sucks tho..
