Depending on the content being displayed, the phone adjusts the display backlight dynamically. Example: when you go from a mostly white image to a mostly black image the backlight is reduced.
I'm not talking about "Adaptive brightness", which adjusts brightness according to ambient light.
I find this behavior really annoying, especially when watching movies. I want my brightness and backlight exactly where I set them.
There used to be a hidden settings app called Content Adaptive Backlight Settings on Oreo (see this or this), where you could disable this behavior.
This app, however, is missing from Pie. I'm not sure if it changed names or what, but I'm looking for the same/equivalent option to disable content adaptive backlight.
Does anyone know how can I disable this? Thanks!
I'm using stock rom, September 2019 update.
I noticed too this behaviour and it's really annoying.
I follow this thread to see if there's a solution.

Hi,
I have noticed the default camera app sets the display brightness to full when loaded. It's irritating since the picture you see on the display when taking the picture is different from when you view it in the gallery.
So I installed Quicksnap and noticed it does the same.
So, do ALL the camera apps do this or is there some way to stop it happening?
Thanks all,
Oobly

you might want to check the outdoor visibility in the settings of the camera
That's with outdoor visibility off. With it set to on it goes even brighter and oversaturates the colours. Anyone else got some feedback on this?
Thank you.
Well, from scratching around in the ROM and looking at kernel source code it looks like the mDNIe settings are to blame. There are different profiles for different display tasks and the camera ones seem to be setting the brightness up. Will play around with the files associated with each profile, maybe I can fix it meself.
Hi there!
For sometime now I want to move to LP but I find too many things that are missing compare to my current KK.
I'm using Lux Auto Brightness on my current device and on LP it caused so problems (fullscreen overlay, presist notification etc..)
I was wondering how is the stock auto brightness of the LP (if it's any different from the current KK) or is there any alternative for LP to the Lux?
Thanks!
I absolutely love the stock brightness settings. You set a desired screen brightness with the slider and it adapts the screen in a way, so that depending on environment light you perceive the screen at the same brightness u initially set. In my opinion it works really, really well.

What is your opinion about the brightness compare to KK?
I recall seeing some very poor performance form the stock brightness management in sunlight.

Stock auto-brightness (erm, I mean "adaptive brightness") sucks on Lollipop IMO. It's another example of something that wasn't broken but Google tried to fix it anyway and utterly borked it in the process.
My experience is that it does not "adapt" nearly enough. If I set the slider to the right level in daylight, when I go into a dark room I am blinded. If I set the slider to the right level in a dark room, when I go into sunlight I cannot see the screen. Frankly I cannot see the screen adapting at all. If it is adapting then it's in within a very narrow range. I even did a software repair to see if that would solve it, but it didn't.
I've not used Lux, but I've not heard good things about it in Lollipop and am loathed to install an app to do something that previously was handled fin by the OS. Stock auto-brightness worked very well for me in KK.

Are you sure that you have adaptive brightness enabled at all? I can see it adapt quite clearly on mine.

I'm using Lux on LP and don't have any issues. The persistent notification can be set so it's only visible in the swiped down notification view, but not perpetually visible in the notification bar (in Lux settings, set notification visibility to lowest priority). What do you mean by "fullscreen overlay?"

You need to add Package installer and SuperSU to the sleep list in Lux.

I just faceplamed myself so hard
I think I found the problem; when battery saver mode is enabled, when it kicks in, it will set your screen brightness to a certain fixed level. But when you charge the phone again and battery saver mode deactivates, it will not automatically re-enable adaptive brightness, so you need to re-enable it manually.
My experience was that kitkat was better on the screen brightness. Lollipop works fine and adapts well, except that in bright sunlight it won't turn up the brightness as much as kitkat did.
Little background: somewhere in kernel code or some other core module of the operation system manufacturers or ROM creators set minimum brightness value for the device. This value was in some of my other devices called min_brightness. I remember faintly that I was able to set the value by running some script in Init.d. Unfortunately I did it several years ago for my other device and cannot remember the details.
The minimum brightness in Colt OS is 31 and seems to be similar other roms, which I tried.
Another option to set the value is Xposed module called Minimum Brightness. Unfortunately it has zero effect on my device. forum.xda-developers.com/xposed/modules/mod-minimum-brightness-t2993161/amp/
Another option is to use app called Brightness Tweak, which does its job somewhat but the result is not exactly desirable. The problem is that it makes the brightness curve not smooth and setting semi-bright values is impossible. It is however able to set the value to 1. https://forum.xda-developers.com/android/apps-games/app-brightness-tweak-t3339579
By the way, I find screen filter apps in adequate because they reduce contrast and add complexity to setting the brightness. Setting minimum brightness affects swipe status bar and brightness sliders as well as auto brightness functionalities. In addition MX Player.

Try to use "ScreenDim" app
Thanks for the suggestion. I tried the app, but in my opinion the brightness adjustment method is very convenient. The is no slider in notification or sliding status bar. Also the min brightness is not adjusted globally so other brightness adjustment method are unaffected.

Have you tried light control app?
No + the phone is broken already. It wont keep charge anymore.
Hello, I have disabled adaptive brightness and when I open some apps, the screen starts automatically dimm a bit. When i exit the app, the brightness returns to normal. For example it does in Chrome, messenger, stock message app, stock dialer, youtube and many more. It does not do in Gallery, weather, camera. It's absolutely useless when im going to type in messenger and screen dimms so i can see it worse. Also i am watching youtube and screen dimms. I cannot understand what is this supposed to mean such nonsense feature.
I want to ask you if somebody of you has faced with this and if he figured it out somehow.
Ive already written to honor support , they answered nothing to the piont.
I was figuring out that when i turn adaptive brightness on, this doesnt do, the screen doesnt dimm when i open any app, but adaptive brightnes randomly fades my brightness setting after switching off the screen.
All i would like is what attributes i have to set to some app that i dont want to dimm. I cannot find this out.
Any suggestions thankfull.
"Online videos and games consume a significant amount of power and may cause your phone to heat up. As a result, your phone automatically decreases the screen brightness to prevent your phone from overheating. The brightness will return to normal when your phone cools down.
Some apps automatically adjust the screen brightness for better readability. For example, when you open Contacts or Messaging, the screen brightness is adjusted automatically even when automatic brightness is disabled."
" This function cannot be disabled"
"The screen changes color in direct sunlight.
When the ambient brightness reaches a certain level (such as direct sunlight), the screen brightness and contrast are automatically increased for better readability. This feature cannot be disabled."
Yes and this is bad. Something like answer from honor support. But also messenger goes darker and it has nothing to do with overheating. When i switch on the adaptive brightness this dimming doesnt do with any app. Also with adaptive brightness off some apps do not dim as if they'd have an exception of this. It is very bad that it cant be disabled this makes this phone completely useless for everyday use because readability goes worse when it goes darker.
Same here
Yup, I have the same. I just keep the Automatic adjustment "on" so it stopes dimming. Which is anti-intuitive. You would expect this dimming beeing caused by that Automatic setting not the opposite. Let's hope they will sort it soon.
Unfortunately its the special feature implemented in firmware called "eye care" as they replied me from honor support. It needs to tell them to switch it off at [email protected]
It seems that Velis Auto Brightness app from Google Play Store does the trick (Honor 10 Stock Pie).
Settings:
Automatic brightness: ON
track light in graph: ON
SETTINGS: (advanced):
Automatic brightness: ON
Disable system handler: ON
Start when screen turns ON: ON
Interactive notification: ON
All other settings off/default.
When you turn off the screen and turn it on, go for the first time in notification area and set your desired value in Velis.
Turn off automatic handling of this app in battery section (app start).

Check in the developer settings for the current value of "Increase readability under sunlight".

Hello, that setting in notification area really worked for me, thanks. But the slider Is in steps 66% , 73%, 80% I cannot adjust it per one % but nevermind, at last this helped me.
edit: after one day testing I noticed that it doesnt work. It still dimms the apps.

Hi, it's a pitty that it does not work.. Maybe Velis app is killed by app manager? As i wrote, try to disable any battery management for Velis app. Do you see after that 1 day Velis slider in notification area? If not, it is likely killed by system app manager.
And yes, it is true that the screen can be adjusted only bys steps.
In my case more than a week for honor 10 (EMUI 9) with Velis and still no any screen dimming issues in any app.

Velis was running but the apps start to dimm anyway I dont know what happened. Even when I set brightness in notification area in Velis, apps dimmed.
Download Lower Brightness Filter :
https://play.google.com/store/apps/details?id=nu.lower.brightness&hl=en_US
Enable the permission and set brightness to 100%.
Then select brightness in phone to auto and restart the phone.
Then select desired brightness.
edit : it doesnt work....
Turn on Advanced visual effect.
I used to have the same problem too. Simply just go to setting>smart accessibility>accessibility>Advanced visual effect>turn on.
If it doesn't work go to developer option and make sure the window animation, transition animation and animation duration are set to 1x.
To enable the developer option, go to setting>about phone>build number>tap until it shows u are now a developer.
Hope it does help u.

Hello, I had it already turned on , in developer options I have all animations set to 1x, but it dimms the screen on my Honor Play with android 9.
Before we can fix that via ADB but now is not possible. If anyone has a better fix please share
It seems like there's some bug either with the app itself or with the phone's color management. When a video on Netflix is playing something happens to the contrast settings and it becomes too washed-out, and that decontrasting thing is visibly disabled when I swipe the phone's menu down during playback. You can actually see when swiping away the menu (to the point it's actually not on the screen any longer) the point where the contrast suddenly jumps between low and (too/black-crushed) high settings.
Changing the MIUI color scheme doesn't correct the problem.
EDIT: I should note that the Netflix app uses its own brightness setting which overrides the system's when content is played, and it along with the contrast thing get disabled whenever a phone GUI element is displayed (even when adjusting the volume the contrast and brightness jump momentarily).
I have same issue with YouTube. I was able to fix it by enabling Disable HW overlays in Developer options. I don't know if it will work for Netflix though.

That worked! Although the contrast like this is, as I mentioned, maybe a bit too much.
Does this setting affect battery life? Because on some XDA article this was written:
"Disable HW overlays: Hardware overlays allow apps that display something on the screen to use less processing power. Without the overlay, an app shares the video memory and has to constantly check for collision and clipping to render a proper image. Don't mess with this option unless you have a good reason to."
What hardware is disabled? Because it says "always use GPU" when I thought using non-hardware processing it means "software executed by the CPU".
