[Q] Brightness Issue. Backlight Broken? - Android Q&A, Help & Troubleshooting

Hi, I flashed a few different kernels recently to test them out. Now my screen brightness is really dim even at 100%. How can I make my brightness go back up? I could even settle for something that just makes the 100% brightness value higher.

Does anyone know if any root config files affect brightness? If so, which ones?

[Q] screen brightness issue since update. help ?

i flashed a 2.1 world generic and ive noticed the screen brightness is much lower than before on 1.6
and if i look closely i can even see the brightness getting brighter then dim again
like every 10 seconds.
i dont like this...i was wondering if anyone else experienced this.
is there a fix that i missed ?
repair your phone with PC Companion.
Why repair? The default screen bright ness is lower in 2.1 and aout brightness is on. Updating/repairing won't change that.
Install Brightness Profiles for market and set up the screen brightness from there.
i will try the brightness profiles until he replies with a reason i should repair. thanks

GB Stock Camera BUG Brightness Level Not Detected.

Hi, got a weird issue. I tried many GB roms and used my stock rom to test it. But it seem like the stock camera do not detect auto-brightness. It only detect the "LAST BRIGHTNESS SETTING" so if you set your brightness level to the lowest it will appear that way on your camera when you use it, but once you switch it back to auto-brightness it still stays the lowest level.
anyone got any solution for this?

[Q] calibrating auto bright control

Has anyone come up with a way for me to calibrate auto brightness? Would like to use it, but it turns display all the way down, and I like it a bit brighter. I'm rooted but locked. Thanks
There's an app called Lux Auto Brightness that allows you to set brightness at various light levels, including min brightness. I use it on my phone and works very well. Not sure on a tablet but worth a try.

What happened to Auto Brightness with the Marshmallow update

Auto brightness... What happened? It used to just work. You know, automatically. If you adjusted the slider it would snap out of Auto mode and lock to what ever you set it at. Going back to full auto was a s simple as selecting the checkbox again in the quick settings.
I don't know if it's part of Marshmallow or TouchWiz but now the brightness slider controls the automatic-ness of the brightness. So its more like a auto "range selector" or "sensitivity selector" it seems. Its more of a semi-automatic mode.
If you set it to ~50% the brightness will adjust +/- 10% around that setting. But it doesn't seem to just automatically do 0-100% on its own anymore.
Set it near 100% and it'll practically refuse to dim in low indoor lighting.
It also seems to respond to whether or not you're holding the phone. It'll get brighter no matter what (thankfully), but it will not lower the screen brightness until you put it down on a horizontal surface... Kind of annoying if you're reading and happen to walk in to a dim room and you're being blinded by your phone until you put it down and then pick it back up. I have Smart Stay turned off so that's not it.
I definitely prefer the plain old, dumb, just works, auto-brightness that I could snap on and off if I needed. Now its...complicated. Why "fix" what isn't broken. Was it confusing some people?
I tried Lux Brightness control app but I'm not sure it's really what I'm looking for. It's too much. I just want "set it and forget it" Automatic (0-100%) brightness like it used to be.
It's a feature. The brightness slider will now bias the automatic setting toward higher or lower brightness while still maintaining the automatic adjustment functionality. Turn off the automatic setting check-box to accomplish full manual control.
What ever happened to just plain Automatic? I don't want to have to mess with a slider. It adjusted the brightness fine before. I find that now it's either too bright or too dim for many situations and I'm constantly messing with the slider. Whereas before, auto was just auto.
Same problem here... It is very annoying

Interestingly, with my old s3 and now my current s6, when looking at battery usage, the screen was always about 15% and usually the second item in the list of things that use the most battery power. It was what I always loved about amoled. Now, screen is number one and comes in at ~50% after the marshmallow update. I wonder if it's because it's always so bright now? Or perhaps they've changed how battery usage is measured. Not much I can do about it. Just an a interesting observation.

[Q] Outdoor Automatic Brightness Not working

Hi
I'm just wondering if anyone else on here is facing the same issue? Or if this is working flawlessly for everyone?
When I have the phone on automatic brightness and go outside on a sunny day, the display will occasionally turn on the maximum brightness mode, but only for about 2-10 seconds and then it goes back to the standard maximum brightness that you can manually adjust it to. It also doesn't go back to the super bright mode after no matter how long I have tried to get it back. I even aimed the screen right towards the sun in hopes the screen would get bright again. The super bright mode works maybe once every time I turn the phone on, and then immediately turns back off, after a few seconds, extremely frustrating.
Is anyone else having this problem or know how to fix it? Maybe there is some way to manually activate the outdoor mode?
Also found this reddit thread with the issue:

Thanks
I also want to have this function manual enable but at the moment I think they don't care about this. The screen is too dim compare with other top phone. I have 2 lg g5 and I think that is the reason I am gonna sell both phones.
It may be too dim in Auto but the maximum brightness is bright enough. I don't need to burn my eyes. The maximum brightness is already too much for day-to-day use.
I do wish :
1. that 100% will be the true 100% of this screen - meaning the brightness boost I get in the sun.
2. the in the display setting, I could set the auto brightness to be + X% of the default value. For example, if I set it to +20%, then if the usual auto mode sets the brightness to 50%, it will actually set it to 60%.
Overall this phone is solid, fast, camera is amazing , sound is good ..Sure, a 3500mah could have been nice but I'm happy.
