for me many apps
like message,contacts,fb,chrome etc.

I'm having the same problem. My screen brightness autodims to zero randomly when I am using Google Chrome. I hope it can be fixed if it's a UI bug.
VTR-L29, EMUI 5.1

hello,
it seems that you need to disable any power saving settings
disable the power genius app if you have it
or use 3rd party app like lux lite
those are the solutions i found so far
if they would release an update soon, maybe they will fix this issue
good luck

Same problem here... Kinda retarded
Sent from my VTR-L29 using XDA-Developers Legacy app

It seems that I have found a solution.
I noticed that (im my case) the screen dims every time when the keyboard pops up, so I have uninstalled google and swift keyboard updates and installed a different keyboard.
No problems with brightness since I done that, so give it a try.
Also, the screen brightness was not reducing when it was on maximum (with auto brightness off ofcourse).

Screen Dimming Temporary Fix

After Oreo update, it seems there's annoying bug/feature that automatically dims my screen when using camera, Facebook, chrome, pubg mobile etc.
I tried one temporary solution for that bug which actually works on my Huawei P10.
Let me know it this solution will work on your devices.
1. Turn-off Power Saving Mode
2. Go to Go to System>Developer Options>Increase Readability Under Sunlight> Toggle Off
3. Then restart and check your apps if it still auto dimming

And if you want permanently freeze or delete power genius...that solved my problem.
But I think because I delete it now in my power usage, software ia not showing...just hardware.
I dont know if its because I delete that or was a bug that I didn't notice))

where is developer options?

hello. I do not know why but it does not help me. only locking and then re-unlocking the screen restores the normal backlight and does not dim afterwards.sorry no good English.use Google translator. Olo

it doesnt help for me. any ide of this???

Works on my P10. Thanks!

Doesn't work on my Huawei Nova 3i

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).

If you disabled animations in developer options, enable them again (0,5x for exanple) and see the magic.
NO more dimming at all.

Hi - I see this thread was originally written 2yrs ago, but I currently have this 'screen dimming in app' problem with my P10 Plus. It started in the last couple of months and may be related to a software update - I'm currently on EMUI 9.1.0.
The Developer option on this thread unfortunately didn't resolve the problem for me (perhaps that's not longer relevant now).
Can anyone offer any other advice?l to resolve this?
Thanks.

Honor Play screen dimming

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]

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.

Before we can fix that via ADB but now is not possible. If anyone has a better fix please share

Screen Rotation Bug

Has anyone experiences screen rotation bug as I do? Some apps (specially facebook messenger) auto-rotates to landscape at startup even auto-rotate settings is not enabled. Though it only happens at startup and never gets stuck on landscape mode, it's pretty annoying.
I know a factory reset could possibly resolve the issue but it's too hassle just for a simple bug.
Build Number: COR-L29 8.2.0.133

nope. it's not. I thought it might be the nova launcher so tried switching back to default launcher but it's not the cause. the bug's still there.

bug is fixed in Android Pie 9.0 update

auto brightness bug?

Hello noticed many times my screen do auto brightness while i have it off.
How do i fix this?
Last official firmware thanks

Unfortunatelly I got the same problem since purchase, none update fixed that. ;/ A bit annoying.
Additionally, after latest update (.190), after every restart the default launcher is set to stock Huawei and I have to go to Settings and change it to Nova Launcher. :/

Its normal for Huawei P Series... it was since p9 or even before!
After Reboot the Settings for autobrightnes restored to default. so it not a bug, its a feature
