Hi
after upgrading my A3 with Android 10 (EU Version) by OTA standard upgrade I also have the issue that the display brightness is often reduced to a very low level even if the brightness automatic is set off and manually set to 100% or 90%. Typical case is when putting the phone after short usage in "stand by" via the power button and then pressing the power button again for reactivation and then the display turns on on amuch lower brightness then before.
Normally i can log in and then switch manually the brightness from high to low again to high level which will give full brightness back. But doing this is really anoying and yesterday i recognized that outside with sunglasses on i cannot read or do this procedure because the phone seems to be of/dark.
So is there a fix for this display problem?
Thank you very much!

So,
Today I was messing around with GO Launcher EX and GO Locker, and I didn't like the performance, at all...so I did a search and found an app called spare parts that was supposed to help the animation speed, after a while of messing around, I noticed that my display wasn't nearly as bright as it was an hour ago. I checked and made sure that the display brightness setting was set to 100%, and that auto-adjust screen power was turned off, and the display was still about half as bright as when I started today.
How can I test if I messed something up? Or is this normal for a AMOLED display? Is there an app I can download that will force the brightness to go to 100%, to see if some app is messing with it? What the heck is going on.
Emmmmmooooo rrraaagggeee!!!
So I got a app that controls brightness , and in fact confirmed that the default controls were only boosting brightness to around 80 percent. What can affect the settings like this? Using automatic brightness, or changing the brightness through anything but this app leaves the screen dimmer than it normally is. I can't even use the touchwiz settings widget.
Interesting.
So, to further report on this odd behavior,
After further investigation, the brightness with auto-brightness seemingly drops light output further than the "0" setting in my brightness app, and further than the slider allows manually adjusting via the settings>display panel. Odd.
So,
I disabled all auto-brightness via the settings in the TouchWhiz apps (read: the browser and the video/audio player), and was just controlling brightness via the app I installed.
Later today, i turned on auto-brightness again via the Power Saving widget, and the issue where the screen dims farther than any manual settings allowed was gone. Again, i only have an issue with max brightness now-- using both the system settings panel to adjust brightness as well as using auto-brightness via both the power saving widget as well as the system settings panel.
So, in summary: the max brightness issue remains, and i can only set it to about 80% without using the brightness app i installed (the app allows me to set it to 100%....where as in the system settings, the slider goes to 100%, and stays at 100%, but the screen looks like its at about 80%. Using the brightness app i installed allows me to boost it back to 100%, but as soon as i change the brightness in the system settings app, or the power saving widget, it maxes out at 80. The slider moves all the way to 100%, but i'm only getting 80% brightness).
Note:
I have no apps installed that affect brightness...0. None of my apps have anything remotely having to do with the display, audio, or it's settings.
Maybe you can help me?
I turned off the auto brightness in the system settings/display/brightness but it seems that the screen starts to dim (sometimes). I hate this...I have to touch the screen to retain brightness. I don't want auto dimming...I want the level I set (which is about half way on the slider).
Where can I find a master override?

Adjust screen timeout. This happens when your screen is going to automatically turn off

Thanks... I'll check it out.
Also in display settings uncheck "auto adjust screen power"
Was there ever a solution to this? I am now starting to get this issue of screen will not respond to 100% brightness...and the option to change display brightness is greyed out in settings. It seems to be a problem with 'power savings' which I would like to completely remove from my phone as even when I turn it off, it is keeping me from adjusting my screen brightness when below 20% battery...and with my 5400 mah battery 20% is a full 8 hour day left...really irritating...only way to solve is to charge above 20%...or go enable power savings, then disable it again...but problem returns every time the screen goes off.
In CyanogenMod, I was a fan of the setting that allowed me to "prevent phone's auto brightness from going down".
I like auto brightness and appreciate its ability to save battery life when indoors vs. enabling me to see the phone if I go outside in a high light situation.
However, under florescent lights, or in a room with a definitive light source (single lamp in dark room)... the phone's sensor keeps jumping it between light levels where the screen brightness goes up and down.... up and down... It's a bit dizzying and makes the phone somewhat uncomfortable to use.
Anyone find an app or workaround to automatically achieve what I want... other than... disabling auto brightness when it starts, setting an appropriate brightness level, and then, trying to remember to re-enable later when I'm outside (and of course, have a hard time then seeing the phone )
?
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.
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.
Hi There,
when starting the "battery saver mode", the display of my phone switches to maximum brightness. I found an article https://www.xda-developers.com/customize-battery-saver-mode-android-8-0/ about settings in android 8 and it kind of works, but only when typing the command "settings put global battery_saver_constants "adjust_brightness_disabled=false" " into a shell (locally or via adb). Next time my phone reaches the "battery saver mode" again, the display is switched to maximum brightness again.
Currently, my phone is running latest LineageOS 16 from this source: https://forum.xda-developers.com/moto-z/development/rom-lineage-os-16-0-t3871409
Is someone else facing this behaviour?
Best regards,
Helmut
It's because the damn led is right next to the light sensor. Light sensor gets blasted with light and thinks it needs to compensate by maxing the display brightness. I've learned to live with it. Alternatively you can disable the auto brightness.
