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).
Does anyone know of a way to get the auto brightness adjustment for the us versions? More specifically I am on Verizon...
You see I would like to extend my screen on time (who wouldn't) without giving up the convenience of auto brightness if I can

So, I spend a lot of time in direct sunlight with my phones. The S4 was unusable. The Note 3 in the current configuration I have it in, is *just barely* tolerable.
I know that if I am on stock TouchWiz, then the "auto brightness" setting will net me the highest NITS (brightness) values. If I go to manual brightness and set it to 100% bright, it still will not be *as bright* as if I were on Auto Brightness.
So being a hater of stock Auto Brightness, I wanted to try out Lux Brightness but then I read somewhere that this app even when set to Auto, will only get you the same peak brightness that the "Manual Brightness" gets you. It cannot get the peak NITS that TouchWiz Auto Brightness offers?
I also read somewhere that CyanogenMOD based AOSP ROM's are hacked to allow you the highest possible NITS that TouchWiz Auto Brightness offers.
Neither source of info for the above two paragraphs were solid though. Can anyone help shed some light (no pun) for me on this subject?
Seems like an odd thing to overlook....
No
thanks
It's on the Tab Pro and Tab S
In "Settings->General->Power Saving" there's an option to enable Screen Output Mangement. This will automatically lower brightness to save power...
...not sure if it act as a auto-brightness depending on the light in the room you're in but give it a try!
Pretty weird samsung didn't include auto brightness on all the tab 3 models this was present.
Don't mean to necro this thread but the Samsung+ application (device health monitor?) has a setting under battery life that can trigger auto brightness if you want. My tablet doesn't have a normal auto brightness so I have to use that.
Auto brightness is turned off on my galaxy s8 + but yet still seems to auto brighten when in the sun. Is this normal? And if so is there a way to keep the level of brightness the phone goes to when in the sun rather than having it dim once moved to a darker area?
