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.

Under what setting is it on the G3 so I can check the G5?

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
I've had the watch since tuesday, but am having a problem with it: when going into ambient, screen visibly dims, but ends up lighting back up... Tried several brightness settings, and it does it with all, except maximum brightness (ie 5).
So basically, when going into ambient, the screen progressively dims, but then brights up and ends up settling at the ambient brightness level it should reach when brightness is set at 5.
Have tried several watch faces, and factory resetting, but it doesn't change a thing.
Anyone experiences that?
Also tried setting brightness with Autowear: only the awake brightness is affected- the ambient brightness always stays the same...
For what is worth, it's particularly obvious with the Dandy default watch face, as it's the same in awake and ambient mode (minus the seconds hand). Set this one up, set brightness at 1, get in a low lit room, and then, I for one see the ambient brightness get dimmer, then get visibly brighter and settle there... Not that obvious in a bright room, but blatant in a dark one.
Also, I realized the watch reports the Android Wear version is 1.3.0.2176821 while it's the latest 1.3.0.2284253 on the phone. Same as, the watch reports the Google Play Services version is 8.1.20 (2283517-534) while it is 8.1.15 (2250156230) on the phone. Don't know if it matters...
Just turn on theatre mode when charging.

That, I already do. But the sun sets long before I go to bed, and lay the watch on the charger. And it's as soon as the sun sets that the watch is much too bright to me in ambient mode...
Guys how are you doing? I'm having a strange issue with my phone, i've searched the forum about it but couldn't find anything about it other than a couple of messages without any conclusion. This problem is mostly noticeable when having the screen in minimum brightness, it's like the backlight flickers a bit. If writing an SMS for example, whenever you press a keyboard key the screen flickers (it's very faint but noticeable). Also, when you open any app, it's like the brightness goes up a bit and down again, it's a very strange issue. Is anyone having this problem? Seems to be a software glitch because if you leave the phone in a static screen, that doesn't happen. It's updated to the latest fw version btw, it always happened.
To make it clear (and if anyone wants to try it), this happens with auto brightness, and the slider set to the minimum in a dark condition, whenever the brightness is medium/high at least i can't notice it.
Hi all, despite 3.2.6 update which has improved auto brightness performance, is still quite far from being good.
The problem is when the phone is unlocked directly under light or in bright environment. After moving to darker environment the display doesn't dim by itself. It has to be turned off and on to successfully adapt. But in opposite way, it works. When turned on in dark, it adapts correctly after going to the light.
It has to be issue within OOS, because on customs roms (cm,aosp based) autobrightness works perfectly. Maybe it is weird but it's bothering me quite a lot
Is there any way how to fix it? Other then install lux, which breaks ability to give permissions due to overlay error.

According to Carl Pie, OnePlus messed up initially on the auto brightness. However, they have rectified it and the current stock implementation is as follows: when you move to a brighter area and unlock the screen, the screen immediately adjusts for the light making the display brighter. But when you move to a darker area, the adjustment is not immediate but it will darken slowly. This is intentional. After moving to a darker area, leave the screen on for sometime and check whether it darkens. If even after some time it doesn't, then it is an issue.
