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.

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.

Whats wrong with manually changing it? It doesnt even take 5 seconds to change the level.

Exactly. Why would you expect your phone to automatically make your life easier or function at an optimum level?

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.

I have a question do to the screen. Whenever im scrolling through the homescreen it randomly dims and gets brighter could that be something with my rom or 4.2 or my launcher?

I think the automatic brightness option is a bit flaky on the N10. Seems overly sensitive to me. You can always turn it off and set the brightness manually.

Is there any way to change default brightness level of the auto mode?

nope, i would manually adjust it.
Was reading somewhere that the magnetic stripe on some of the cases can interfere with the light sensor. Not sure if OP is running inside a case or not.
At any rate, mine also does the same and I have it in one of those cases that auto-shuts the tablet off when closed. It does not bother me too much yet.

This would be nice. I like the auto-dim feature but it drops a little lower level than I prefer.
When I'm in a light room the screen goes brighter but if I walk into a darker room, the screen doesn't dim unless I lock and then unlock the screen.
Anyone else having similar issues?
Yep got the same here. Thought I had a faulty ambient light sensor but obviously not.

Just tried it by covering the light sensor to make sure, no problem here (G935F). My only concern related to brightness is that the s7 just has auto brightness, but no adaptive brightness.
Uncheck the auto box and recheck. Then don't touch the slider. It's usually because in marshmallow the slider moves with the auto bright and most people touch it which makes it hold position.

There seems to be a bug somewhere still. I just tried to move the slider while auto brightness is ticked and to cover the light sensor afterwards again and it still worked and to my surprise it even took into account that I lowered the brightness and took also a lower brightness at the covered state and took my initial setting after uncovering, pretty nice, so there is indeed still adaptive brightness. After ticking und unticking auto it went back taking the default steps for brightness as before.
Having the same issue here
Definately not touched the slider.
Also, I have tested the light sensor and it appears to work fine so definately a software issue. Though I imagine we will see some software updates to fix bugs shortly after the official release date.
So you can adjust the slider with the box checked and get various levels of auto? Does it learn?

Yes.
I can't tell for sure, when I change further steps the previous seems to stick, at least to some extend so there is a logic behind it, but I can't tell for sure if it really is based on each step and sets it accordingly or if it's just changes the range it operates in. Anyways I'm a happy camper.
Also, I could reproduce the device not changing the brightness, when I put it to full at darkness it won't move anymore in auto. But as soon as I lower it again it will also change accordingly again, maybe at those with the stuck brightness the min brightness is only raised, but not lowered anymore, but just an assumption and doesn't help anyone atm unfortunately.

This is the first Galaxy phone I had, that Auto brightness actually works the way I like it.
It seems to be working fine now. It just takes a few seconds for the screen to dim (maybe I was being impatient).
After testing it further it's actually really good auto brightness.
It works, just takes some time to adjust to the lighting. Maybe the default settings are set to a certain time. Maybe with root we can adjust this..

It seems to only do it quickly when the device is lay down (as 954wrecker said). Maybe Samsung did that so it doesn't annoy you when using your phone.
this is definitely a bug imo... the auto brightness doesn't change for me either...

I also have an auto briteness issue, when I disable AutoBrite and set it manually about half my apps override the setting and enable AutoBriteness in the app's screen usually dimming the screen? SpadesFree one example and I do not see an override in the app.
Confimed that I'm having same issue, auto brightness not adjusting and slider not movingoing. Have to move it manually
Same issue. It needs to be fixed manually by editing services.jar (root needed)
Nothing else will work. None of google play apps will help with that issue. Does not matter what you do, it will always dimming if you don't fix it in framework.jar

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.
Yes, I've seen both.

The backlight on the buttons is very dim, yea. I think that pic was just in good lighting to show the lights well, I don't think they are any brighter than what we have. I wish they were brighter as well.

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.
