Screen Brightness: I have set the screen brightness to medium and and timeout to 60 seconds. I have started to notice that it will change the settings on its own. I will notice the screen is dim then look at the brightness setting and it will be set to minimum. Another thing that is driving me crazy is that it will dim the screen if you don't touch it regardless of the screen time out.
I have also noticed that sometimes when typing the screen does not follow were the words are going.
Other than these two minor pet peeves I absolutely love this phone. If it had a vag it may replace my wife.
The screen dimming is probably done by u. If u run your hand back and forth at the bottom of the notification bar it will change your brightness. Auto brightness has to be off. Its a cool feature that the original epic had.

u might want to disable the "power saving mode"... i had the same issue as u, but it seems to be fine since i disabled power saving mode
That's the thing I have my settings to auto brightness off
Edit: I will try turning the power saving mode off
Did not know that about the notification bar dimming the screen that's a cool feature.

Thanks I bet the notification bar might be it. That is awesome, I can't believe I didn't know that yet.
IF your in the internet browser that came with the phone and you turn up your brightness all the way and then you notice while your look at page all of a sudden your brightness will go back down to like 10% I found out the culprit.
the browser has a BROWSER BRIGHTNESS option in the menu. you can turn auto on or theres another slider there and it appears factory setting is all the way left or lowest.
this was pissing me off today while I was waking in the sun, I thought I had my brightness on all the way but with in 5 seconds while look here on XDA, the brightness kept going back down on its own and I do not have auto on. the thing I was doing to get it back up bright again was to do the notification swipe to the right and that would only temporary fix it.
While I'm at home in the evening, I've been trying to turn my brightness down to the lowest level. I tried the system slider and also tried different widgets and apps bit there has been one issue with all of them. Every time I put the phone into sleep/lock, the brightness setting doesn't stay are the lowest setting. (Auto-brightness off). The brightness would reset to 20 - 30%.

There's probably an app you have installed that is messing with it

Go to
Settings --> Display
There's another option called "Auto adjust screen power" which auto adjusts LCD brightness as well.
Just a guess really.. Hope it does something for ya
Is it possible to decrease the backlight of the phone even further than the minimum (for using in bed)? I tried modifying the min brightness setting in build.prop and it makes the brightness slider go further down, but it doesn't actually get any more dim. Is there any way to set this other than using a "screen filter"-type app. Thanks!
Yaab from the market, try it out

use and app called screen filter. it places a transparent layer over the screen and dims it further. it works better on amoled than on led lit screens since amoleds don't use a backlight. with led backlights it doesn't dim it, just darkens the images (backlight level remains the same).
I can't remember why I settled on Display Filter instead of Screen Filter. But there's another option for you.
My old Nexus 7 2012 flicker as hell when the brightness is totally dark with low wifi signal active. I wonder if the new one has the same problem???
My tablet flicker when:
1. Weak WiFi signal.
2. Backlight dimmed to under 30%.
3. A program that constantly accesses the net. Such as Google Maps.
Thanks
Mine does, oddly I think I'm the only one experiencing it.
Turn off auto-brightness if its on.

I tried that, put brightness to about 30%, then bam, my backlight shut off! Took me forever to turn the brightness above 30% to get it to come back on again.
On the new 2013 Nexus brightness at the completely lowest setting is never completely off! It should just barely be lit but in a dark room you can clearly see the screen even at the very lowest setting. I keep mine at way under 25 percent, or much less than a quarter of the way and its comfortable enough to read indoors. I also keep Auto Brightness turned off and don't get any flicker.

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
