Brightness reduced when some apps launched

With auto-brightness turned off an brightness turned up all the way, I am seeing the brightness go down when some apps are launched and turn back up when the app is closed. I noticed this today when launching GoChat and then also saw it when launching the stock jellybean web browser. I am not sure but I think this has only been happening since the last software update (T-Mobile USA).
I wonder if others are noticing this and if it is occurring on I9505 models or just T-Mobile models.

Is power saving mode on?

From DisplayMate:
Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.​From Samsung:
Samsung Adapt Display: The Galaxy S4 "learns" what you are viewing and adjusts the display's brightness accordingly. If the phone senses you are reading an article, for example, it will illuminate from a more muted brightness.​

I'm experiencing similar issues as well with my S4 I9500.

power saving mode = off
auto brightness = off
auto adjust screen tone = off
still the same problem.
I see the thread talking about 33% briteness reduced during web browsing, but this shouldn't be if all brightness reducing settings are off.
And it certainly should be with other apps. My texting app has a dark theme where background = black and text = blue. When this 'feature' reduces my screen brightness when I launch that messaging app with the dark them, it becomes difficult to read.
So they are trying to save us from ourselves... and save their battery bragging rights... but PLEASE SAMSUNG, give us options to turn all this crap off!!
So... maybe I'll have to root and reROM. Just don't want a ROM with more issues than I already have with stock ROM. I hear other ROMs aren't so good with our camera.

I have the same annoying problem.First the wifi issue which we don't know if it is hardware or software,then this,i am wanter what's next..

Turning off auto-brightness reduces screen brightness by up to 34%.

No sir, Not always! Sitting here in a bright office with white walls, filled with sunlight and fluorescent light, with auto-brightness off and brightness turned up all the way, turning ON auto brightness reduces the screen brightness by quite a noticeable bit.
I've read this stated a few places that auto-brightness can actually push the brightness up higher than is possible with manual brightness, but under what conditions? It would make sense that auto would select the brightest possibility under direct sunlight conditions, but I just tested it outside under direct 11am sunlight, toggling back and forth between auto and manual (turned all the way up) -- no difference! Auto brightness did not make my screen brighter than is possible with manual brightness turned up all the way.
All.... as posted in another thread, this only appears to be a problem when launching the browser. My problem with GoSms chat was remedied when I toggled back to 'normal mode' (from it being accidentally set to 'night mode' at some point -- oops! why would an app have its own brightness setting? this should only be a global variable).

Screen Too Bright in Dim Ambient Lighting

The screen is too bright for me at home during the night even when brightness is set manually at zero. The odd thing is the phone has a dim mode when inactive that is very dim. Any way to manually access the phones inactive dim back light?

Sorry, I see using battery saving mode lowers minimum brightness.

I use this app, 'Screen Filter' during the dark.

If you only want to dim brightness download and try something like Yetanother auto brightness (YAAB) from the store.
It goes lower than stock and had a night mode.

Screen brightness/flickers

I'm finding when browsing that my screen brightness seems to auto adjust randomly ..I don't have it set on auto or anything, it's annoying. Any idea what's going on?

[Q] auto brightness

Running stock 4.4.4 and noticed that auto brightness the screen doesn't stay constant, it will fade then brighten. I was running with steady brightness but battery usage was higher than I'd like so I set auto. Don't like the way it constantly adjusts. Is this a problem with other Nexus 10's?

Hi,
It's normal for auto brightness. Please avoid placing your hand over the illumination sensor, as it is responsible for changing your brightness, so when you put your hand over it the tablet will identify the current illumination is dark, therefore the screen will reduce the brightness, and as soon as you remove it'll do the opposite. Auto brightness is all a matter of getting used to it IMHO.

Makes sense, didn't think of that, I hold it vertical. Thanks

Try using LUX which is more customizable, including response times to dim or brighten

AOD brightness is way to dim at night

Hi
The AOD seems to be bright in the morning but when it gets darker in evening it remains readable for only a few seconds and then dims down so badly that one cannot read anything on the AOD at night when there is pitch darkness.
I did set the brightness option in the AOD settings but that doesnt seem to help at all.
I'm not using Auto Brighness control also for the display.
Anyone else seeing this particularly at night?

Yes, in low light conditions the aod is to dim...in normal light conditions the aod is good!
Hope they fix it in an update!

Are you using any type of screen overlay?
Sent from my LG-H872 using Tapatalk

Yes i use Lux-Autobrightness, but deactivated the overlay-right. Otherwise some system animations wont work...like blur in the power off screen, also you cant install non playstore apps with some type of overlay active (android security-feature). But Lux is not the problem, aod is also to dim without lux! Aod simply sets the screen brightness to low in dark enviroments.
