[Q] Can someone explain auto brightness on S4 - Galaxy S 4 Q&A, Help & Troubleshooting

Like topic said, when I set the brightness slider to auto, I can drag it from -5 to +5. What is this and how does it affect the autobrightness?I find the phone to be too dark in a lit room and to bright in a dark room. Will dragging it either way make a difference? And what does it do? Is "auto" not "auto"?

Is it really so hard to understand? When brightness is set to auto you can use this slider to make screen more or less bright in the same conditions. Another words if you think that auto brightness sets illumination always too dark you can drag slider right or too bright drag it left. But unfortunately if your screen is too dark in one condition and too bright in another this slider won't help you.

My screen is too bright, what will make it dim below "10"?

Even on the dimmest settings, the Vibrant is too bright for me in bed, where the light disturbs my wife.
It seems that, with root, you can lower the brightness further - at least on other phones. Is there any way to do this with the Vibrant?
Thanks!
The "Dimmer" app will toggle it from your current brightness down to 10 but if you find something that will go lower let me know.
It has an automatic brightness control based on input from the sensor. You may need to disable this in the settings too, but I would think it would be automatically dimming itself already in a dark room.

Right, but that doesn't get dim enough in some situations and the minimum brightness you can select manually is 30. "Dimmer" will take it all the way to 10 but I would like to see something that would take it to 1 or 2.
I agree. It's too bright in low light situations.
If you find a solution please post it.
Try the Screen Filter App from the market. You can get UNBELIEVABLY low brightness. Which means much better battery.
+1 on screen filter. New version now dims taskbar too.

How to reduce notification brightness?

Even with the least brightness selected for the display, the notification in lock screen comes with highest brightness. Any way to reduce this ? This is usually too bright for in a dark room.

Changing Brightness Curve

Hello everyone,
after having had most roms from here on my N4, something bugs me on pretty much all of them: When Auto Brightness is selected, the Phone is way to dim in sun light. When i move the Brightnes slider the display gets really bright, but as soon as i release it in max position, the brightness goes down to maybe 70% (might be lower).
So is there a way to "costumize" the auto brightness curve the phone uses so that it goes up to 100% brightness faster?:good:

Anyway to turn off auto brightness for second screen?

It's too dark to use sometimes unless I lift it up, making it hard to see notifications quickly. (When main screen is off) When it's on auto, it gets too dark most of the time unless it has direct view of light. Any way to turn off auto brightness on it or make it brighter?

Do you experience brightness issue?

I've noticed weird brightness issue at Auto Brightness turned off and when I set it at full. It is actually going even brighter when is brighter outside and it's getting darker again when going into darker environment and it is making me crazy because firstly I don't want my battery to drain more when using brightness sensor and actually don't like the feeling of brightness going up and down that's why I TURNED OFF autobrightness. Could you reproduce the same behavior?

Yes i have this when dark mode is turned on, Even with Auto brightness off it will still change the brightness when i am outside in the bright sun and it also changes the way the text appears adding sort of black lines on the edges of the letters (to give it more contrast ?). It's a feature not an issue i think it also doesn't happen indoors even when lights change. For some reason it only happens when it's very bright outside.

Yeah, but every feature should have "turn off" button, but Xiaomi couldn't help it with forcing something on us as always...
Under Settings/Display/Contrast & colors try using either Increased contrast or Standard. NOT Automatic contrast.
