Auto brightness not working correctly - Samsung Galaxy S7 Edge Questions and Answers

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

Auto screen brightness doesn't work?

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

Automatic backlight broken or just badly designed?

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.

My screen is too bright, what will make it dim below "10"?

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.

Crappy Automatic Brightness Sensor?

Is it just me or does everyone's Epic's have terrible brightness sensor hardware/software? My sensor seems to have about 2-3 settings of brightness, and goes from completely dim to super bright in random situations and nothing in between.
Cyanogen just posted on his twitter that in the past he changed the sensor's abilities through coding modifications. Could we do something of the sort for the Epic's sensor?
Agreed. The sensor is horrible. Also, the transition between brightness settings when set to automatic is near instant instead of slowly transitioning, which makes it more obvious that its changing brightness.
I would agree that it is terrible. Mine also send to sometimes turn auto brightness back on if I've turned it off.
It would be great if someone found a way to mod the code for it!

I thought the screen was just too bright at its lowest setting. Fortunately someone came up with a fix for it that can be found in the developer section. As far as the automatic sensor I would suggest turning off "Power Saving Mode" in the Settings>Sound & Display as well. I've read somewhere that this causes the brightness level to vary on its own.

Hehe, that was me. Stay tuned for more. I have coded up and will post, tonight, a new version that will let you modify the brightness curve (from the command line, for now)
As for automatic mode, I have figured out how to modify some aspects of it at the kernel level, such as the ambient light thresholds at which it switches to a different brightness level. By modifying the brightness curve, we can achieve at least some more control. But to make it really good may be significantly harder.
Personally, since manual brightness is always available by swiping horizontally on the status bar, I have little desire to use auto mode anyway.

The sensor is actually pretty sensitive. It's just that Samsung chose to have a really small range of brightness steps for automatic brightness.

More like they installed an awesome dimmer switch and lights, but the fixture only does three modes; high, medium, and still pretty damn bright.

is there an app/mod to adjust auto brightness settings?

I'm on Android Nougat 7.0 stock with TWRP and root. The auto brightness goes too low when in a low lit room. Previous versions of Android adapted as I would increase the brightness and eventually learn how I liked it in differently lit rooms. However, Android 7 doesn't appear to be doing this.

Adaptive display is to adjust the colours not the brightness.
Turning off auto brightness would mean adjusting the brightness everytime I went into a different light environment. That would defeat the object.
Not very helpful but thanks for trying.

you could always turn off auto brightness and try and find a middle of the road setting, but I know what you mean, when playing games on mine the screen seems to go darker in darker rooms, seems the wrong way around to me, I just move my hand away from any sensors and it sorts itself out, the 2 dots next to the top speaker.

Well on Android 6 I would manually adjust it when it was too dark or too bright and Android would remember and adjust it to how I liked it, meaning I didn't have to manually adjust it anymore. Android 7 doesn't seem to have it. I guess I'll just put up with manually adjusting it for now.
Lux. It would set how dim or how bright the screen would be in a certain level of ambient light.
