Using stock 4.0.1 here, and have always had the brightness set to auto. But it never seems to do anything? If I am in a light or dark room it is always dark, often darker than the lowest brightness setting.
I am just worried that the sensor might not be working, if the phone needs to be sent back it needs to be done soon. Anyone else with this issue? I know the sensor that turns off the phone screen when in call works, but the auto brightness might use a different one.

Auto brightness is just simply low on this device. There are some hacks in the dev section to increase it...but they don't work on my ROM.
I just started using juicedefender to adjust the auto birghtness
So auto brightness itself is broken and sensor is pry OK? I wonder if there are any apps to test it.

Simply put a bright light to it and watch the screen brighten up. The sensor is fine.. auto brightness simply is a little too conservative, probably because more people would moan about battery life than screen brightness.
My auto brightness works just fine. Sometimes I have to the screen off then on for it to adjust. Other than that, the levels are fine. I'm on 4.0.3.

Has anyone noticed that their auto brightness is kind of broken after upgrading to JB? For example, if I'm in a really bright area and go into dark, the screen does not dim itself, however this can be fixed by going into settings and un-checking and checking the auto brightness box.
Obviously this is pretty annoying... Is there a fix for this?

I've noticed the same. It stays bright a lot of the time in dark places. I haven't noticed it staying dim in sunlight though.
To me, the way it was before seemed broken. It would constantly change its brightness level. This was effected by the light reflected off clothing, etc
I love it now

He he good one
But I Dont find any issue with it either. In fact, if you dig in, you'll find the process consumes 30% lesser battery than before ie. Screen + sensor timing and refresh for both...

I'm actually pretty sure this is the default behaviour for ICS as well its only 3rd party roms that added in the ability to auto dim as well as auto bright the stock way is it only goes dimmer if the screen turns off and back on other wise it stays at the maximum brightness
Sometimes if I'm using the widget to move from full to auto brightness and tap very fast, it'll sit at full brightness. If I toggle slower its fine. Definitely some bug there.
I think auto brightness is much better in 4.1.1. Before it was far too dim, now it seems just right in all conditions.
I'm using the app "Lux Auto Brightness" and it couldn't be doing a better job.
Definitely check it out if you're unhappy like I was with the stock auto-brightness
Sent from my Galaxy Nexus using xda premium
that has been the default behaviour from ages for stock goole rom:
the autobrightness only can increase...it doesn't decrease, unless u lock and ulock the phone or check and uncheck autobrightness
that the intended behaviour google want..the brightness get increased, but not decrease..
So you're saying that the auto feature in 4.0.4 was broken then?

Yes, it delayed the lock screen and when I set my phone down under a bright lamp and it woke up hours later in pure darkness, it might soft reset.
happens to me as well on stock 4.1.1. if I'm in a dark room and put the phone under a lamp or something, the brightness goes up instantly, but it never comes down until I lock/unlock the screen again.
in fact most of the time I think the thing is too bright (but that may be because I come from a nexus one always on the lowest setting since the autobrightness there didnt really work well).
it's a minor annoyance definitely
Same Problem with Note2!
Hi guys,
found this thread during my search for this brightness issue. My Galaxy Note 2 has the same strange behavior. But I figured out something: when I lay down the device to a table or bring it to 0 degrees in my hand, automatic brightness it's decreasing perfectly! Can you confirm this behaviour at your nexus? I guess it's a kind of strange Samsung " feature", maybe?
Thanks, Michael
Ahoy, I was also researching my auto brightness issues when I found this thread. I can confirm the behavior from the previous post on my SGS2 on Jelly Bean 4.1.2.
If the phone is in vertical position and I do the lamp test, it will stay on maximum brightness no matter what, but in horizontal position dimming works perfectly.
Regards,
zytrel.
Has anyone noticed stock auto brightness is equal to the LOW setting? The only thing it does, whether it's a dark room or bright room is flip the brightness to LOW.

I don't have a case yet.
I agree that auto-brightness is too low. I manually set the brightness.
I agree the auto brightness is pretty low. However I like it, and it saves battery.

The auto brightness is to high for me too. In low light conditions if I turn off the auto setting I can force the screen lower.

I notice when the screen dims especially on auto dim that the screen flickers or strobes like the tail lights on cadillacs, I cant read any thing easily. The best way to see it is to quickly scan from the top of the screen to the bottom or vise versa in a dimly lit room, you will see a stepped image.
That's why I haven't used stock auto-brightness since my last HTC phone. I've used third party apps to control my brightness, since I had the original Note. Lux is my favorite. So much control over the brightness settings. You can control the lowest brightness setting the phone will hit in addition to numerous other variables. Works really well for me.
Mine works flawlessly. It usually is set at the lowest setting until needed to be boosted.
This gorgeous screen still suffers from being too damn bright in the dark! Needs a filter on it so your retinas don't burn in the dark.

I had to use lux auto brightness to lower mine it was very bright. You might want to use it to increase yours if it's low .
Just curious if anyone else is having this issue.
I have the box checked, but I found myself manually adjusting, thinking it just wasn't very sensitive. I turned on auto brightness, moved the slider all the way to dim, went out to the sunlight, and it had no effect. Unchecked, and rechecked the box, restated the phone, did the opposite in a dark room... No effect.

I believe the slider sets the maximum brightness. So when you go out in the sunlight the spot where you placed it is the brightest it will get.

I thought that also... But when I had the slider at full bright, with auto turned on, in a pitch black room, it should have dimmed, correct?

Looks like my phone might be doing the same thing... I'm wondering if I should swap my phone out before it's too late to exchange it for an S4.

Yeah, you're right. Do you have a screen protector on that might be interfering with the ambient light sensor, by any chance?

I don't think it's a bug. The auto brightness on some LG phones doesn't work like the rest of Android phones. On some LG phones, you set the brightness to a certain level and the auto brightness will work around that particular level.
Say you have it at 75% brightness and auto brightness on, the level will go up to maybe about 85% while outdoors and maybe to about 65% in a dim room. Set it at 35% brightness with auto brightness on, the level goes up to 45% in a bright area and 25% in a dark area. That's how my old iPhone 4 used to work.

The way you described the functionality is what I have witnessed mine doing. I had to play around with it for a few days before I figured out what it was doing. No matter which level of brightness I set, auto brightness will adjust up and down from there based on ambient lighting. I do like having this option since it basically lets you further tweak the auto brightness to a comfortable level. On my other phones, a lot of the times the auto brightness was either to bright or too dark compared to what I would have preferred.
I thought there was something wrong with the auto brightness on mine as well. I have it on 70% auto bright set and it never seems to change. I have a screen protector but it has cutouts around the camera and other sensors and ear piece so I knew it wasn't that and I also tested it prior to putting the screen protector on.
Seems odd that LG would go a different route on what auto brightness is compared to the rest of the Android OEM's. sort of defeats the purpose but perhaps that is why we have to keep the setting so high to begin with.

I got mine to work. Its kinda strange. I was playing around and I shot a video as I played the video back I hit the menus button and there is a setting for auto dimming so I check it and my phone dimmed so then I checked to see if my main auto brightness would work so I went into settings and checked auto bright there too and the screen dimmed. Havent been outside yet but before this the setting did nothing see if you guys can get it to work on yours.

Yes, autobrightness on LG works this way since ICS was rolled out for LG Nitro. At 100% even with autobrightness screen will not dim, and at 0% level with or w/o autobrightness screen will not light up.

No, it's right way because brightness sensor works different than human eye and like was said here other phones usually set brightness too dim or too bright using that sensor.
I also think the work Auto Brightness is on the phone E980 strange ... I do not see any change in brightness depending on the ambient light ... Not like all the other android phones

If that is the case, why is there no effect of ambient light on the screen??? The brightness remains the same whatever be the light condition.
I thought my phone had the same issue as everyone else but noticed this weekend when I stepped into a very bright area my screen automatically adjusted the brightness to a higher setting.

Mine has worked from day one and better than my GnoteII I upgraded from... As others have said, it's configured around the amount of brightness you originally set it to.
where is the light sensor of the OGPro located...?
Well the autobrightness wasn't working as I wanted it to. Never had issues with it before on other devices.
So I downloaded Velis auto brightness
I noticed the sharp brightness sensor was sometimes juming between 2 values like 552 lux and 12 lux causing a constant change off brightness. (flikkering)
Could someone check the brightness sensor, and check if it also fluctuate? My S3 keeps steady values...
I had a faulty pro8.4 (dead pixels) on the first day and the auto focus was also not working properly.So I would like to know wheter I have an other faulty tablet or it is just the sensor that reacts differently.
thanks in advance
I have noticed the same thing. When I am scrolling through a website I notice the flickering brightness. I ended up turning the auto brightness off.
My auto brightness just doesn't seem to work at all. It just defaults to lowest brightness. Funny thing is it worked on first boot, but stopped after the very first time I turned the screen off then back on.

I installed CM today and using auto brightness, I can confirm it just goes up and down, dim-bright-dim-bright. It's disappointing that such a nice tablet has a piss-poor brightness sensor.
From my Pro Tab 8.4
My Lux values were all over the place too. Luckily there's an application on the Play Store called Lux which fixes everything. Just set it to adaptive. That's what worked for me.

Can you go to Settings >> Display >> Brightness and then click the settings icon and then the Adjust button. That should tell you the value of the sensor as seen by CM.
Does it really fluctuate there? If so, can you maybe take a quick video so I can see what you are seeing?
I'm pretty sure this is a hardware issue. My sensor flips +/-1 when I leave the tablet sitting there. Covering the sensor drops in down to about 0 and then it bounces right back to the same value when I uncover the sensor.

Wow Thanks so much for suggesting the Lux app. The stock auto brightness jitter was driving me crazy, especially when scrolling around in the playstore.
On a side note, samsung screens are hella bright when viewing at night. Going to put Lux on my phone too lol.
A autobrightness mod I use on my Nexus 10 is the XPosed framework and Gravity box module. Your can set the brightness and lux pair values then reboot. On my Nexus 10 it took three days (night/day) conditions of tuning values until I found the sweet spot. It was not too much of a bother and I've not had to make any adjustments since. Look in Gravity box for display tweaks then all settings can be modified but the pair values mentioned above are under autobrightness levels.
