For some reason starting yesterday, my phone brightness automatically goes to minimal brightness everytime i lock it. The brightness slider is on MAX (and it stays on max even when the brightness dies). Auto Brightness is OFF. Power Saving is Off.
Presus Kernel
Omega V16 rom.
nothing modified in the phone in a long time. After the issue happened, i updated the kernal, and still nothing.
The only thing that happened differently over the last few days was i used my phone too much to the point the battery would die. (and in general the screen turns to minimal brightness past 5%, but somehow this got STUCK. even when the phone is charging

Still doesn't solve the issue.
Wiped the device, new rom (Wanam), New Kernel (adam's).
Still the same issue.
Here's what happens:
Full Brightness, Lock screen,..... Unlock, Minimal Brightness
OR
Full Brightness, Lock screen,..... Unlock, (.5 second of full brightness), Minimal Brightness
Just to be clear, the problem isn't that the stock brightness isn't bright enough. The problem is that the brightness setting gets turned down to zero for no reason, (while the settings and slider) are still on max
Do you have any apps that might be doing it? That's the only thing I can think of, maybe you've set up a Tasker profile up wrong and is causing it or something.

well tried Wanam with Adams kernel
then
tried wana with Stock kernel . Wiping before every install.
Both didnt work.
So i wiped every thing. /Data, /SdCard, /Cachem etc. literally everything. Then installed wanam with adams kernel. And somehow that fixed the issue
Everything was fine. I had the brightness set to 60%, which was reasonably bright for me. Retrieved the phone from the table to place a call and realized the screen was looking dim. I thought perhaps I'd accidentally turned on Auto Brightness, but I realized it wasn't the case. I restarted the phone, but the problem still persisted. I did a factory reset; still the same. I reflashed the firmware, but saw no resolution to the issue. Incidentally, after the flash and the subsequent setup, I tried to increase the brightness, but the phone refused to permit it, with a message about some heating issue. I was able to do so several seconds later, however, and while there have been no more "heat" warnings, the phone's brightness hasn't been the same. I seem to have lost about 20%: what I had at 60%, I have the same level of brightness now at 80%. And the maximum brightness, on the same token, isn't the same as it was earlier. I'd appreciate any suggestions. If any of you have faced a similar problem and had a found a solution to it, do let me know.
weird ... Guarantee if still possible.

That's pretty encouraging...or is it? Nevertheless, would've appreciated some solution, but it looks like I'm going to have to make that trip to the service centre.

I saw in a review before i bought mine that if it heats up the brightness of the screen is auto. lowered in order to try to keep a resonable temperture. But nothing about your simptoms. Did you try a different kernel here on the forum or to reflash the stock kernel ?

I've an LG Optimus G too.
It can happen two things:
First, the phone takes down the brightness when the temperature is too high, it happen automatically.
Two: Auto brightness is enabled. Then, the phone uses front camera to see how much ambient light are everytime, then it go up and down.
You're talking about the first case, so charge the battery 100% and then unplug it and let them alone for some minutes in order to leave the temperature going down. Then go to setings, screen, and disable smart screen snd auto brightness.
Try it for some time and send us your experience! =D

There is ambient light sensor near proximity sensor,camera is not used for automatic brightness.
He can disable temperature warning with Optimus G Tweaker which can be found in Play Store.
He must be rooted firs,he can do that easily with framaroot app.
Thanks a lot, everybody. Unfortunately, I've sold my OG and moved on to the Nexus 4. I appreciate your responses, nonetheless. Have a good life ahead!

:good: Thats right, in the opposite of the front camera you can find the proximity sensor and the brightness sensor, if you have eye-recognizement enabled in block screen options, then i think it uses the front camera for both things (brightness and eye-reco.).
Near the front camera it only has notification led.
I'm root, but i dont know if someone want to desable temperature warning... it can be... destructive! LoL
Hi guys, I don't know if this is supposed to be either a feature or a bug, but since I replaced the battery cover from the original Quick Cover folio case (CCF-210) to the non-folio one, everytime I charge the phone the Notifications LED becomes dim as if brightness setting was set to zero. I have the unlocked AT&T E980 model immediately flashed with Panama ROM (full stock, non rooted) since I bought it a month ago. I made a few tests to check if this is a hardware or software issue (if it's an issue at all) and so I did the following:
* Using the non-folio case, when phone is NOT charging, the LED brightness is NORMAL (i set it to 80% brightness)
* Using the non-folio case, when phone is charging, the LED brightness is DIM (as if 0% brightness). I check the settings it's still set at 80%
* Using the Quick Cover case (auto screen off is turned ON), when phone is either charging or not, the LED brightness is NORMAL
Is anybody else experiencing this? Is the phone supposed to do this or not? I'm thinking of hard resetting the phone, but I wanna make sure I'm the only one experiencing this before I do.
No response from anyone? I guess I'm alone on this one...

I do know that when charging your phone there is a setting for the LED to change the colors or disable it, on certain roms. that's the only thing I can say about it.. sorry I wasn't more help

Thanks for the response. Yeah, I tried changing the settings and then testing it again, but the LED keeps on dimming out (dropping to 0% brightness) when I connect the charger. LED works fine & normal when the charger isn't connected. It's nothing that affects performance though, it's just a really weird and annoying behavior.
Since it looks like I'm the only one experiencing this, I'd probably try to hard rest one of these days (when I'm not lazy anymore hehe) and hope it fixes the weird behavior.
how to make it brighter in general
i was gonna ask a similar question, are you saying the notification LED in home button right? Mine is so dim when charging, i can hardly see it, I have seen it much brighter when powering off phone and turning on phone, how can I make it brighter at all?
I am on ROOT E988 version by the way, stock ROM

Yes, that's exactly it. So it's not specific to just the E980 Panama ROM since your experiencing the same on your E988. Same here, I can hardly see the green notification or the red breathing light when the charger is plugged in, especially during daytime. So is this supposed to happen or is it a bug? Do anyone else notice this on your LG OGP?

Cool!!! Thanks. Saved me from the hassle of doing a factory reset. :good:
Is there a way to keep the screen from dimming after a period of time? I set it to never turn the screen off while charging, but it still dims while the music app is up when it's charging in the car which is annoying. I can't find the setting anywhere in LG's settings or in tweaksbox.
I tried Lux as others have suggested but it still dims in my truck. Very annoying.

My screen doesn't dim ... did you turn off Auto brightness?
What would cause it to dim by itself? I only run at 61% brightness so maybe I haven't experienced this yet
My auto brightness is off and it still dims. Lux auto is on or off and it still dims.

Yup, I always have auto brightness off. It just dims after a minute or so of no input - which happens while I'm driving. I always keep it at 100% unless I'm in the dark which may be why you haven't noticed it - the screen may dim to around 60% anyways. I find it weird that you can't adjust how long it waits to dim, or turn that feature off. I'm guessing this is part of LG trying to help with battery life.

I've only ran into that a couple times and the screen dimmed to 90-95% and I had to manually turn it back up. This is different where it goes bright again as soon as I touch the screen and the dimming is much darker than 90% - more around the 50% ballpark.
Wow, yeah that sounds extreme...
I know it's a pain, but have you considered doing a hard reset to see if it is indeed setting/software related?
If the OP was referring to the "Screen brightness lowered due to high temperature" message.
Go into the hidden menu by typing 3845#*855# (replace 855 with your devices model number, mine is a D855).
Then scroll down to Thermal Daemon Mitigation OFF and make sure it is enabled (on).
Reboot the device and you can now force maximum brightness all the time.

I actually had to get a second phone a week ago because I cracked my screen (a few hours before my protector came in the mail). At least it was early enough that I got a brand new phone through insurance instead of refurbished, but both phones do it. Could be a Sprint vs Verizon difference - Verizon likes to go crazy with phone mods lol. Though I don't normally run into it with normal usage - only when the screen is set to stay on while charging through the developer option and I'm driving with music.
Mine does that. Sprint phone, happens after a minute of no input, including when the screen is set to stay always on. However, I notice this doesn't happen when running Maps.
I've already gone through two phones, same on both.

There are certain apps - and Maps is definitely one - which will not allow the screen to dim or the device to sleep. (YouTube is another for example, also iHeartRadio, etc.) Really the best thing to do is mod using something like Tasker or Stay Alive! as I mentioned in an earlier post for specific apps. I use mine for the Music app since typically I've got mine on the car charger and dash mount and it makes no sense to go through a whole screen unlocking routine to fully operate music after a while.
Anyone else having this issue? Sometimes in well lit indoor environments, it will be dimmer than I expect and then suddenly ramp up to full brightness.
Likewise in dark environments it will be dim and ramp up suddenly as well.
Yeah, I have that aswell, sometimes it's not perfect at all, I hope there will be some optimizations.

Glad I am not alone. Hope they'll be good with software updates since currently they are known for not being good in that department.
I was really happy to see that option in settings. However I was irritated by how erratic it was. Disabled it.
Even ambient display doesn't work correctly for me everytime. It's kinda random too
To be honest, I think it's partly a Marshmallow issue, as none of my MM phones have had decent auto brightness

I wish I could agree. My Nexus 6 had great auto brightness on L and M. Never had this type of behavior until the OP3.
Might be because OnePlus has implemented their own content adaptive back light like on the OPO. I turned it off by setting a 0 in the file /sys/devices/virtual/graphics/fb0/cabc
Not sure if that file is there on the OP3 but it's worth a shot

I turned it off in the settings and it was fine. I just wish I could have normally functioning auto brightness lol.
I just got my OP3 and have an issue with adaptive brightness, not sure if this is a behaviour that others have seen or if I have a defective device, perhaps someone could advise? My phone is running 3.2.1 and is fully stock, I have adaptive brightness enabled as I always have on whatever phone I use, when I activate the screen or it turns on at the receipt of a notification the brightness is at the approximate level it should be according to the position of the brightness slider and is perfectly usable. After a few minutes, this varies a bit but never more than five minutes, the screen dims to what I think is the lowest brightness level which during the day makes it difficult to see anything on screen. I can get back the previous brightness setting by turning the screen off and then immediately back on but then after a further few minutes it will dim again. The phone is not responding to any change in the ambient lighting as this is always constant and there is no obstruction to the sensor on the front of the phone. I can get a constant brightness level by turning this setting off but it can be a pain having to manually adjust when I go outdoors for example and this isn't the way I like to use my phone. So, is this a hardware fault or just a very poor implementation of adaptive brightness? I'd appreciate any feedback as this is spoiling what is otherwise a great phone.
Thanks
What should we do for this scenario. Should we raise a complaint or wait for an update. I have my phone in warranty. I am sure all of us would have it in warranty.
I've had issues with that feature since day one with my op3. No update has fixed the adaptive brightness issue, and it's the same with all of the custom ROMs I've tried. Has to be an issue with the phone. I'm hoping a software update fixes it because it's an obvious issue. In dark light, my screen dims so much that I can't really read anything on my screen.
Auto brightness is just bad on the OP3.. I've installed Lux to ease some of the problems but I'd like the standard AB to work correctly and not need an additional app..
Can´t dim the brightness at all CM13
Hi,
I have an issue were I can´t dim the brightness at all!
Killing my eyes!
Any solution?
With last 3.5.2 is been solved
