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.

Screen Brightness Keeps Changing

I took off the automation for the screen brightness and I manually set it. However, after about a day and a half it changes by itself. I can not figure out what is changing it. I use Dolphin browser...but I don't think that is changing it. Does anyone why the screen brightness is not static?

for web browsing the brightness setting can be different then the phone itself .. idk if thats what u mean but just a little fyi ... since the update however if its set to auto ive found the web browsers brightness is not adjustable

For me it was doing the same thing till I noticed that the drop down curtain at the top of the screen is a manual brightness adjuster as well. If you happen to drop it down just enough to see the date and move your fringer to the right it brightens, if you move it to the left it dims. I found myself pulling it down and accidentally changing it alot until I figured out why. Since then it never changes now that I know to pull the curtain straight down and don't move left or right with it.

Another setting that I noticed would randomly adjust the backlight brightness is Settings -> Sound & Display -> Power Saving Mode. I've disabled this and my backlight no longer changes an I have noticed no difference in power consumption (with it checked or not, the display consumes a lot of power ;-)

This was sooooo frustrating for me until I found that setting and unchecked it. When I turn off auto-brightness, I don't want the brightness changing unless I change it lol.

That's gotta be it! Is there anyway to disable that?

setting it to auto brightness will

This sounds kind of funny when I had autobrightness and the powersaver automation on the battery would drain faster. When I turned it off the battery lasted longer.

Have you ever accidentally swiped on your notification bar? This will change the brightness and it's supposed to be some shortcut to change the brightness.

Same experience here. The auto-brightness really keeps the screen pretty bright at all times, it just dims it a little bit in dim lighting. If you set it manually, you can keep it dimmer than the auto-brightness will ever dim it.

Crappy Automatic Brightness Sensor?

Is it just me or does everyone's Epic's have terrible brightness sensor hardware/software? My sensor seems to have about 2-3 settings of brightness, and goes from completely dim to super bright in random situations and nothing in between.
Cyanogen just posted on his twitter that in the past he changed the sensor's abilities through coding modifications. Could we do something of the sort for the Epic's sensor?

Agreed. The sensor is horrible. Also, the transition between brightness settings when set to automatic is near instant instead of slowly transitioning, which makes it more obvious that its changing brightness.

I would agree that it is terrible. Mine also send to sometimes turn auto brightness back on if I've turned it off.
It would be great if someone found a way to mod the code for it!

I thought the screen was just too bright at its lowest setting. Fortunately someone came up with a fix for it that can be found in the developer section. As far as the automatic sensor I would suggest turning off "Power Saving Mode" in the Settings>Sound & Display as well. I've read somewhere that this causes the brightness level to vary on its own.

Hehe, that was me. Stay tuned for more. I have coded up and will post, tonight, a new version that will let you modify the brightness curve (from the command line, for now)
As for automatic mode, I have figured out how to modify some aspects of it at the kernel level, such as the ambient light thresholds at which it switches to a different brightness level. By modifying the brightness curve, we can achieve at least some more control. But to make it really good may be significantly harder.
Personally, since manual brightness is always available by swiping horizontally on the status bar, I have little desire to use auto mode anyway.

The sensor is actually pretty sensitive. It's just that Samsung chose to have a really small range of brightness steps for automatic brightness.

More like they installed an awesome dimmer switch and lights, but the fixture only does three modes; high, medium, and still pretty damn bright.

Auto brightness not working correctly

When I'm in a light room the screen goes brighter but if I walk into a darker room, the screen doesn't dim unless I lock and then unlock the screen.
Anyone else having similar issues?

Yep got the same here. Thought I had a faulty ambient light sensor but obviously not.

Just tried it by covering the light sensor to make sure, no problem here (G935F). My only concern related to brightness is that the s7 just has auto brightness, but no adaptive brightness.

Uncheck the auto box and recheck. Then don't touch the slider. It's usually because in marshmallow the slider moves with the auto bright and most people touch it which makes it hold position.

There seems to be a bug somewhere still. I just tried to move the slider while auto brightness is ticked and to cover the light sensor afterwards again and it still worked and to my surprise it even took into account that I lowered the brightness and took also a lower brightness at the covered state and took my initial setting after uncovering, pretty nice, so there is indeed still adaptive brightness. After ticking und unticking auto it went back taking the default steps for brightness as before.

Having the same issue here

Definately not touched the slider.
Also, I have tested the light sensor and it appears to work fine so definately a software issue. Though I imagine we will see some software updates to fix bugs shortly after the official release date.

So you can adjust the slider with the box checked and get various levels of auto? Does it learn?

Yes.
I can't tell for sure, when I change further steps the previous seems to stick, at least to some extend so there is a logic behind it, but I can't tell for sure if it really is based on each step and sets it accordingly or if it's just changes the range it operates in. Anyways I'm a happy camper.
Also, I could reproduce the device not changing the brightness, when I put it to full at darkness it won't move anymore in auto. But as soon as I lower it again it will also change accordingly again, maybe at those with the stuck brightness the min brightness is only raised, but not lowered anymore, but just an assumption and doesn't help anyone atm unfortunately.

This is the first Galaxy phone I had, that Auto brightness actually works the way I like it.

It seems to be working fine now. It just takes a few seconds for the screen to dim (maybe I was being impatient).
After testing it further it's actually really good auto brightness.

It works, just takes some time to adjust to the lighting. Maybe the default settings are set to a certain time. Maybe with root we can adjust this..

It seems to only do it quickly when the device is lay down (as 954wrecker said). Maybe Samsung did that so it doesn't annoy you when using your phone.

this is definitely a bug imo... the auto brightness doesn't change for me either...

I also have an auto briteness issue, when I disable AutoBrite and set it manually about half my apps override the setting and enable AutoBriteness in the app's screen usually dimming the screen? SpadesFree one example and I do not see an override in the app.

Confimed that I'm having same issue, auto brightness not adjusting and slider not movingoing. Have to move it manually

Same issue. It needs to be fixed manually by editing services.jar (root needed)
Nothing else will work. None of google play apps will help with that issue. Does not matter what you do, it will always dimming if you don't fix it in framework.jar

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.
