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.
I have auto dimness unchecked, and whenever the brightness is set to over 55%, after unlocking the phone it always auto dims byitself.
Is this normal? no other phone does this. Can this be bypassed somehow? It's jarring when you unlock and see a bright vibrant screen and all of a sudden it dims like 10% or so after 5 seconds.
Phone auto dims when it starts to heat up regardless of your settings.
Otherwise it shouldn't as long as it's not set to auto brightness.

Ok, but when the phone hasn't been used in 30 minutes, and not "hot" at all, this still happens. This also happened with the G3 as well.
Is there a way to turn this off? This post has over 100 views, can everyone please comment if their screen does the same thing? Are there any solutions?
What carrier/model do you have?
I just tried this on mine, Verizon, 611A software.
With Auto Brightness disabled, set to 40%, I powered off, turned it on, then unlocked. The brightness did not change. Then set it to 100% brightness (Auto still disabled), and did the same thing. Again, the brightness did not change.
I have, however, seen the screen brightness reduced when I'm using Auto Brightness. If I turned it off in a bright area, then unlock it in a dim area, the screen will be bright for a moment, then will turn itself down, presumably based on evaluating the current ambient brightness.

auto brightness is always off. It's the AT&T non rooted stock version. I just tuned brightness to 70%, powered off, powered on, and after unlocking and opening chrome it auto dimmed within 5 seconds.
Does it do it if you don't open Chrome?
I've seen apps make their own brightness adjustments (like a camera app that maxes out the screen brightness when it starts up). I want to say that Chrome (on my last phone) is one of them. Alternately, turn it on, unlock, wait 15 seconds, THEN start Chrome. If it still happens right after Chrome loads, then it's a Chrome phenomenon, not a just-turned-on phenomenon., and at least you can isolate what to chase down.

Yes it dims even if I don't use chrome. No matter whats on the screen it dims a little after 5 seconds.

Download LUX (couple of bucks) set it to manual, 100% brightness on all LUX setting areas and it will bypass LG's lame attempt to hide the fact that they can't make a phone that doesn't suffer severe battery drain and overheating.
Your problem is called High Tempurate Thermal Mitigation (throttling). I depise it but with LUX, I tell the phone what is acceptable to me, not the other way around.
If I wanted to be dictated to like a submissive I'd just get an iphone.
I don't doubt that excess temps can cause the phone to adjust its behavior. But that quickly after turning the screen on? That seems really fast for something to go over-temperature, and for a sensor to also detect it that quickly. You may be 100% right, it's just not something I'd expect to happen that quickly.
This is a serious suggestion, despite how it may sound What if you put the phone in the fridge for 15 minutes or so, then do the same test? Does the screen still dim after 5 seconds? Depending on the humidity level, the phone could start to condense after coming out of a cold environment, so use your best judgement.
For a "safer" test, hold it in front of an air conditioner for a few minutes, with the screen off. Then, still at the A/C, turn the screen on, and see if it immediately dims.
If it suddenly runs for a while before dimming, then I'd agree it's likely temperature-related. If it still behaves the same way, then perhaps it's a different cause.
Either way, Lux sounds like a nice addition to these phones, from everything I've read. I've just been too cheap to try it yet But the rather coarse auto-brightness from LG has me curious.

Have you tried the cool-down suggestions (fridge, A/C,) ?
Try installing ThermoCF to monitor the battery temperature. I find that when used for GPS (mounted on windshield) the screen will dim with direct sunlight. The temperature is in excess of 120 °F when this happens.
I just left the G4 screen on 50% brightness for about 5 minutes and the temperature remained 98 °F (this is on a wireless charger, next to a warm laptop fan exhaust). I switched to 100% brightness and the battery temperature increased to 100 °F over the next five minutes but no dimming has occurred. After a few more minutes the temperature dropped to 99 °F with the screen remaining at 100% brightness.
Different from your problem but: I turned on the developer options and set the screen to "always-on when charging" and have noticed that the screen dims after some amount of time (I haven't timed, maybe 15 minutes or so). I ended up here because I was looking for a way to change that time and may download the LUX app to do it.
Nice to know I am not the only one having this problem. I use my phone to play Ingress and sucks the battery dry faster than anything. The screen kept going dim as I was charging.
I also have this same issue on my G5. I've tried the Lux, free version, and it still dimmed on its own. I wonder if the paid version will help out my situation?

I like the auto-dim, and my phone seems to accept manual "guidance" as to how I prefer the auto-dim to work.
What I mean is that I can manually bump up the brightness slider (while auto-dim is checked/enabled), and the phone will auto-dim using the brighter setting. Or, I can bump the brightness slider down, and auto-dim will remember that and adjust the brightness.
So it's like you can control the baseline setting for auto-dim by using the brightness slider with auto-dim enabled, and then the phone will auto adjust from that baseline. I play ingress and during the day I bump up the slider, but during the night play I'll decrease the slider and still enjoy auto dim both ways, and preserve the most battery that way.
Aint looked to see if g4 has got it. I know g3 you go into hidden menu. And turn the thermal mitigations on and it stopped the throttle down. Lg has an insanley low throttle down temp.

On the g3 and g4 its under main hiden menu. I use shortcutmaster to get to them all. But the g4 the options not there. Im not sure i dont know anything about the g5. Im not interested in it at all. I am selling my g4. So i can get another g3.
Now i know theres an app 3ctoolbox. And in cpu settings you can modify the unclock temps i dont know if it does the screen.
So, the hidden menu in Marshmallow, here it is folks. Where would I be able to find the option to turn off screen dim do to thermal mitigation? Anyone have any ideas?

Mine also started to auto dim with auto brightness off. I have the H812 from Bell . I'm sure that on mine it's the proximity light sensor that is faulty or in the software. Because when i turn on the phone while blocking completely the proximity sensor it doesn't dim anymore. (knock knock doesn't work while sensor is blocked) but problem comes back if i wake up the phone without blocking the sensor. I have tried it many times and it's the same thing over and over.
Calibration in the hidden menu doesn't fix it, Lux and many other brightness apps iv'e tried don't fix the problem lol
I also use lux with cf.lumen
Lux will manage the auto brightness as per your preferences because i found the stock LG screen was about 15% lower than id like in all environments.
Cf.lumen actually changes the colour of the display rather than applying a dumb screen filter on top for night viewing.
The only thing Lux does for me is dim the screen twice since the phone already dims by itself 3-4 seconds after the screen is turned on. I can guaranty it's not an overheating problem, even after 30 minutes in the fridge it does it. I'm tempted to have the proximity sensor changed but will most likely wait for LG to release 6.0.1 to see if it will fix it.
Nougat 7.0 is days away and still no 6.0.1 MM for the G4. Pardon my language but LG really sucks . This is my first and last LG phone
Hi I Just want to ask why does my Z5 P takes about a few seconds ( 8-10 seconds ) to achieve full brightness after turning on the screen from sleep. For example, after activating the screen from sleep and going directly to instagram, I noticed that my phone isn't on full brightness but instead a bit dim( lets say approx 70-90% bright if basing on the brightness slider in settings). As I scroll at the pictures, I can see it slowly going to full brightness after 8-10 seconds right before my very eyes. Is it supposed to really act this way? I find this very annoying and bothersome as this happen not only in instagram but in fb and browser as well.
By the way, I always set my phone on full brightness and the adaptive brightness disabled. Smart Backlight Control also disabled. So what gives????
Thanks.
I do not have such issues... Min to max it changes immediately.

Hi. Thanks for the reply. I'm not talking about the moment while youre moving the slider min to max or vice versa. What Im saying is that my brightness has always been placed at max with adaptive brightness turned off and yet when I activate the screen (for example to browse instgram or google chrome) , it doesnt go full brightness right away but instead takes approx 10 seconds to achieve the max brightnes (you can actually see the screen change it brightness right before you). I find this behavior weird. Can somebody do me a favor and try browsing instagram in a very dark room and observe if the event is also happening to your unit.
Thanks.

You are right if I set the screen brightness to minimum and turn on adaptive brightness it stays at minimum brightness... Must be a software glitch...
Sent from my SO-03H using Tapatalk
anyone else experiencing this. Still happening on my phone.
I just tried to do the following to see if I can repeat this issue as well.
Turn off adaptive brightness --> turn brightness to max --> load up a page on google chrome --> turn off display --> turn display back on
The screen was on max brightness every time I did this. Although I don't have access to a really dark room right now (in the office) but I can try again when I get home and see if this reproduces the issue.
