Can't control my screen's brightness - LG Optimus Black

Hello everybody,
The problem is the brightness of my screen. It is usually at the minimum brightness(or even lower than that because I can't see anything under sun) and I can't change it. Sometimes it is a bit brighter when I restart and sometimes I can control it as it should be. It does not change anything when I change the brightness settings. I tried other firmwares from
http://luivit.altervista.org/firmwareP970/index.php
but did not work still the same!
Help please guys...

Do a hard reset if not already done

I tried but did not work... Any other advice?

what do you mean about "can't change it" ?
can't find the menu ? option is blocked ? change is possible but no result ?...

Does the automatic brightness setting work? Be it optimized or power saving mode.... I mean try putting your device under light and dark alternatively.. if your brightness doesn't change automatically then problem could be with your light sensor!
Then It's a hardware problem not software one.. and no attempt of flashing any Rom can help you with that. If your device is within warranty, then just flash any basic Rom without rooting it and visit a LG service station!

[Q] Ambient light sensor not working :s

Since a while, I've issues with my ambient light sensor : autobrightness sometimes worked, sometimes not.
Now, it doesn't work at all anymore.
I've tested the ambient light sensor via service test, the value remains stucked to 0...
Do you think my light sensor is broken ???

It looks like it's broken. Do you have warrenty? send it for service, don't forget to relock bootloader before you do.
service test always show 0... try AndroSensor from play store and u will see under light that value is changing under bright light

Thanks. It stays stuck at 0.000 lux with Androsensor. It must be broken...

Hum... after reboot, it works again, and I can see the value changing in AndroSensor. But it will fail again, I'm pretty sure... I should try a factory reset to see if it fix the issue.
If you have Xperia T then it's a known issue as in JellyBean the ALS is broken and always shows 0. It fixes itself after the reboot (still showing 0) but it breaks again after a while.

Yes, I've just seen your thread... But I've been using JB for 6 months and this problem only occurs since 1 month. No hope to definetely fix this, even doing a factory reset ?
You are a lucky one, I wish my sensor was working for such a long time...
In my case I tried everything - different ROM and kernel combinations but the ALS was always dead after a couple of minutes. The only solution was to get back to ICS...

Outdoor Mode (hidden brightness menu, WHY?)

title says it all, why is this hidden and can only be accessed thru settings, and it's not a one time toggle, you'd have to go into settings every time you pull your phone out. just why? would be great for the brightness slider to just go to max instead. anyone know if theres any mods for this? or just what this is about, seems strange.
i dont have this mode
what android version u have

Mine always stays where ever put the slider. But then, I have auto brightness off.
Yeah what version you got? Wish we had outside mode.
I have a 950F exynos 128 GB, and It does not have such setting...
Because it's samsung. They will probably never make a good software. Just search for "automatic brightness bug". They just ignored this problem. No wonder they just hidding that option.
Outdoor mode can be enabled by editing something in system folder. Most of custom firmwares provides that function.
I've never seen that setting on mine. It's automatic for me.

IT is not a bug, and yes, there are ways to increase brightness beyond standard maximum, I remember from the days of my note 3, that many people posted very bad screen burn in and excesive batt drain when changing the lines to attain the most bright screen possible, same applies to speakers, might as well get blown, The auto brightness in note 8, in fact is very well implemented, because it learns your preferences, that is, if set to auto, and you move the slider, whenever the phone detects the same lux level, it will set the level you chose, infact, when in autobrightness, when sensing too much light, it will set an extra ammount of brightness

Agreed. Works very well. Was using GPS Google maps for the first time yesterday, screen was automatically too bright. I used slider to lower brightness, it learned my preference.

Since long I haven't seen any Note device (at least International versions) have Outdoor mode enabled by default unless you are using custom ROM. But this mode i have seen available on low range samsung devices. Actually it is hidden and one minor change in settings app enough to enable outdoor mode.
I will try to make small app without making changes in setting app, though it might needed root access.
Thank you dr ketan! I have used your excellent roms and kernels in my note 3 and 4
As I said y'day, I have made and posted Outdoor mode Tool on my Facebook wall.

hey something cool came out of this post, awesome!
so the app acts like a toggle to turn on the outdoor mode, pretty cool!
Works perfectly. Thank you.
Have noticed this mod seems to time out after 15 minutes or so. Any workaround for this?
@ dr.Ketan: since updating to oreo your app does not work anymore... do you have a solution?
THX in advance!
I am on oreo too and working fine. Check you have granted su permission

XZ2 brightness flashing problem

Hello!
Sometimes, especially when downloading an app from Play store, when installing finishes, screen in XZ2 flashes for like 0.1sec. It goes very bright for a moment and then everything goes back to normal. Anyone knows why is that? I'm up to date with everything, ans have disabled everything connected with screen in settings, including adaptive brightness.

Do you use additional screen white balance in settings? It looks like this was the trigger for me. In certain situations it looks like phone forgot the options for color calibration and moment later was back to definied settings. So I set them back to default and since then no problem (despite more bluish screen comparing to custom white ballance settings of course )

Turn off aod
Aod ?
toniq1 said:

Always on display. Sametimes it's help but it's probably fault of ambient light sensor or screen.
It is the same If aod Off
Not good
That's a common thing with faulty oled screens, it is a hardware issue
I have the same flashing screen when I turn the screen off before the aod is displayed. It does not happen all the time. Turning off aod does not help. I doubt that it is a hardware issue as the flashing started after updating to MIUI 11 - at least for me.
I have also this problem, started a while ago when I was on MIUI 10 after I installed some kind of dark theme
This indeed looks like a AOD fault cause turning it off solves the problem, and the latest version of AOD with custom picture customization, reduced this issue for me
But it also seems like it mostly happens when the ambient light is low so the automatic brightness reduces the screen light and AOD starts to flash
I hope it won't be a hardware problem
One other thing that I want to mention is sometimes it goes really bad and the screen starts flashing for a long time, in this case phone seems to become unresponsive as not touch and not the fingerprint sensor and infrared camera doesn't work at all

It is used for past time if you're asking
So a little update on the flashing screen situation
I disabled auto brightness and set the brightness a little below middle of brightness bar and so far so good. No flashing here for a while
Also disabling the AOD completely solves the problem
Another update on the state of this flashing issue, after Android 10 update haven't seen any flashing so far, AOD display works fine, light sensor and automatic brightness work just fine.
I guess it was a software issue after all
I hope you have solved it. Do you have the anti-flick on?

Nope I don't
Anyone else who has this issue:
Try disabling hardware overlays in developer options, also check to see if the Game driver option within Developer options is set to default. Although its possible that this could be the beginnings of a hardware issue, it could also be a software related issue.
If none of the things that I mentioned work, i would try reflashing the stock fastboot rom. ( must be fastboot version)
Similar happened to me but i think this is not recoverable.

No matter what i do, it only flashes and nothing else is visible. Device purchased about 1.5 years ago.

You need to return to stock using a fastboot rom, using a recovery rom will not work.
Most likely you have corrupted files. but sure it could be an hardware issue, especially if you have dropped the phone or installed something to increase the refresh rate. If you flashed a refresh rate mod, then you need to flash the DBTO image from the fastboot stock rom.

I have TWRP installed and thought of checking it out but it simply flashes there as well. Right now i have the display on, set never sleep in Developer options and simply keeping it up until new phone arrives. Once i am on new phone, i will try factory reset on this first and go from there i think. Not sure how to get to fastboot when display is not working.
Due to such weird nature that nothing really helps i tend to think that this is HW issue.
EDIT : Turned off display by accident (because phone call happened) and now it's back to flashing disco with absolutely nothing working. Fastboot (power + lower volume key together) is of course flashing as well so inacessible.
Happened to me too. Turned off AoD, restarted, turned on and it was ok for a while. Now flashed again. Dont know what is causing this :/

I also got the same issue on my dipper. The only solution that works perfect is by flashing to LineageOS 17.1. I know it's an OLED screen faulty but Lineage really fixes it. Been using Lineage for a few months and never have this display issue again. Other custom ROMs can't fix this display issue.
