Hi, My T-Mobile DVP's auto brightness doesn't work after i upgrade it to mango. It worked in pre-mango, if i cover the light sensor or light it up, the screen brightness would be changed. But it isn't like that in mango (version 7720), no matter i do, it is always at the lowest brightness level. The light sensor still works well in EM, it can detect lux value so i think this is a faulty OS firmware.
So after upgrading to mango i lost two sensors: compass and light sensor (Well, compass still worked in EM in pre-mango but in mango it doesn't work, even in EM). I lost my faith in Dell, too . My Dell laptop dead one month after end of its warranty and cannot be repaired, now this one ...
Anyone have the same problem ?

Hmm its not instant and it takes 5-6 seconds to adjust, because the light sensor is working fine in the EM app it means its working fine with the phone, also covering with hand doesn't work. Try putting it under a couch then put it by a windows on a sunny day.

Doesn't work for my DVP. I think this should be mango firmware's fault, so all DVP should have this problem. Could you please let us know which version your DVP is ?
Anyone who has upgraded to 8107, do you have this problem ? If the problem is fixed in 8107 i'll think about upgrading it manually
Try this: Turn off auto brightness, change the brightness from low to either medium or high, then turn auto brightness back on.
For some reason the brightness setting (that is inaccessible when autobrightness is on) functions as a limit when autobrightness is on. If it's set to low then autobrightness will never raise the brightness above low. Set it to high and try it again.

Good finding ! It worked ! But there is another problem . That is when i light up the sensor, it bring the screen brightness to the highest level, but it suck in that level even when i cover the sensor. I waited 2 minutes but it just didn't change, it was always on the highest level. Then after i locked/unlocked, it turned back to the lowest level.
So auto-brightness is not a completely unusable like compass, it's just too faulty to be able to use

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?

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.

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

so whenever i restart the phone or set the phone's brightness to manual and turn the auto brightness on,the auto brightness slider wont work...i have to shoot some light on the sensors and then the slider works again and brightness gets adjusted accordingly...anyone else experienced this bug?or is it just for me and should i replace the phone?

Everything is fine here man after update.
Brightness slider works fine after update .
it won't work for me too, not even in Good lighting condition, should i replace it? it was working fine till yesterday.
Yea same problem for me.
Same thing happening to my "max pro m1"
whenever the "Auto brightness" is on the brightness slider doesnt work/respond at all.
I tried almost every thing..........
1) Installed latest Update "15.2016.1805.318" of 66.76 MB
2) Restart Multiple times
3) HARD RESET the phone
Still not working
Is it a because faulty/bad light sensor
OR
will it be fixed by some software updates in coming future...

But it just a software bug
I installed android pie gsi
There was no such problem in the rom
Adaptive brightness totally stopped working after I upgraded to 8.1. Turning it off/on returns brightness to 16% no matter how I play with the brightness itself, whether while adaptive brightness is on or off. Covering the sensor has zero effect and it used to work pretty well.
Edit: phone is ta-1003
Little update with the incredibly useful reply from Nokia support: (/s)
Welcome to Nokia Mobile Care!
Some time the brightness screen is not working, I understand the inconvenience that you face. it is depend on the sensor and condition, on the all brand phone face this issues. do not worried. you can restart the device. make sure that if you use screen protector for sure this issues exist.
You also can take manual action if disabling enabling take you time. I hope you understand.
Also you can take 3rd apps from play store to try is that working better.

I have the same issue with the auto brightness setting: it goes to 11% and that's it. Not sure if this started after the N 8.1 update.
Where is the ambient light sensor located on the phone?
