[Seemingly Solved]New to LG G3 D851, Annoying brightness problem!! - G3 Q&A, Help & Troubleshooting

I just got a G3 and every time I reboot, the brightness resets itself to 100%!!
Auto brightness is off.
Is this a known issue? Is there a fix? The phone is rooted with twrp recovery.
Please and thank you!
Seemingly solved edit: So I pop in the sim card after getting everything set and rooted and all that jazz...Why would a sim card not being inserted prohibit the brightness settings from sticking? I couldn't tell you. First for me.

What if you set the brightness as Auto ?

Even if the auto brightness is on, the brightness always defaults to 100% after a reboot. If the auto brightness is on when I reboot the phone, the auto brightness is off and at 100% when the phone comes back on.

Edit: Ok, not only does the brightness setting not stick, the screen timeout defaults to 2 minutes as well!!! Highly annoying, these two little bugs. HELP!!! :crying: :crying: :crying:
I usually use Nova Launcher, so I got around to installing that and it didn't make a difference. I've removed the slider from the notification tray, done a factory reset through twrp...nothing helped.
Really hope this isn't something I have do just "deal with". I'm about to get around to deleting all the nonsense LG and Google put onto the phone...hopefully it'll have some sort of positive impact.

Did the SIM card fix your timeout issue as well? My phone came with the sim card pre-installed but my screen timeout resets to 30 seconds after every reboot.

Anyone can help me please?
If I use the buttons at the pulldown menu to set the brightness to automatic it goes back to 50% after a cuple of time. When I set it into the Settings Menu it works normaly.
Good to know that I'm not the only one experiencing this irritating anomaly. Anyway, I have not found a solution as of yet. I'm running the latest build, and the problem is still there.
Problem solved by a member of telefonino.net (maorr):
-Open build.prop
-Search this line "ro.config.disablesmbacklinght=true"
-Change in "false"
-Reboot the phone
Now the problem is gone :good:

[Q] Screen Timeout and Brightness Settings not Persistent

I am using LG G3 D855, up to date version. My problem is if i set Brightness Auto , and Screen timeout 30 sec. After every restart it keeps Brightness resetting to 100% And Screen timeout to 2 mins. Did Factory reset, Without Signing in to Google too. Still the same.
Should i Flash the orignal firmware again ???

I was doing without sim card !! got a sim card inside and worked ! so dont forget to insert a sim card
I'm having a similar issue with my AT&T version. I set the screen timeout to never turn off and every time I restart the phone it's back to 30 seconds.
I have a couple of LG G3 D852's...both exhibiting the same issue. Another D852 saves the settings just fine even after reboot/restart. Thing I also noticed is that when powering off the 2 D852's, I'm unable to power them back on unless I do a battery pull as well. Not sure if this is just coincidental.

BEWARE!!! YUREKA stock cm 12 users

This bug deserved a new thread.
If you've updated your phone to cm12, 5.0.2 then DO NOT DO THE FOLLOWING:
1. in Settings>Display and lights DO NOT keep "Adaptive Brightness" and "Color Enhancement" switched on at the same time. If you do, and then EVER try to manually reduce the screen brightness to minimum, YOUR SCREEN WILL BO BLANK. PERMANENTLY. Not kidding.
AND IT WILL NOT RETURN TO WORKING CONDITION without a factory reset.
Things that won't work:
1. Pulling out the battery and trying to reboot it. Nope. Been there, done that.
Hope CM takes note of this.

Cure for it
well i have experienced it. but to avoid it you can choose the option
setting>status bar> and check Adjust brightness by sliding across the status bar.
so whenever the screen turned off you can swipe on the top from left to right so that brightness can be adjusted again!
you dont have to reset your phone.

I faced this today only.... screen went completely blank for a few sec, although I was not aware of this bug, but the brightness slider on status bar saved me....
So many bugs in this CM12.... huh...
and the screen off effects are gone as well after CM12 ugrade...

happened to me also.... I thought it was a problem with a theme... so i initially rated it 2 stars on play store, but after i saw it was a problem with cm, i went back and gave that theme a 5 star rating...
SOLUTION!!!!
It is still possible to take control over your phone in this situation. If your screen goes blank, this doesn't means that your phone has stopped working, the phone is still functional and you just have to find a way to increase the brightness. If you ever encounter this problem just swipe the screen twice from top to bottom to open the status bar and then slide your fingers on the screen where the brightness controller is present. This will surely solve your problem without any factory reset bull****. Please note that during this complete process the screen will remain blank. I have tested it a hundred times and it works 100%.
this works ... instead of factory reset

how to set the display contrast
or colour enhancement

Just install vysor in your pc and plug your phone to the pc. Now control your phone using your pc and increase the brightness same wy you reduced it. No need for any factory reset. Hope this helps.
you should Try this
Facing The Phone to Direct Sunlight or if in the night. face it near to the bulb. It will adapt light from the bulb and screen works then you can turn off adaptive brightness. That's works for me.

Does everyone's screen auto dim?

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

Brightness Problem after boot

Every time I boot my lovely handset the brightness is maxed out no matter where it was positioned via the slider in the settings menu previously. It takes a good couple of minutes to sort itself out and within that time the screen flashes/glitches ever so slightly as if it's trying to remember the above settings. I can move the toggle slider left/right and there is not much of a change either. Weirdly if I tap the back of the phone when this is happening it will change the brightness on every tap. After this initial booting time it is perfectly fine and works as it should and doesn't happen again until reboot. I am on stock everything and this has happened on 1.30 and now on 1.80 firmware(s). Only a slight annoyance but I'm more worried about hardware failure. Does anyone else have or know about this problem?

Yes, mine is super bright on boot and shutdown, too. I actually thought this was by design.
