[Q] Screen Brightness - Galaxy S II Q&A, Help & Troubleshooting

Hi,
When I go to settings to try to change the level of brightness, this is greyed out and cannot be selected.
I have tried tuning the auto brightness on/off but nothing doing.
I can however adjust brightness by swiping the top bar (the one with the time, battery etc on it).
Any ideas? Am I just missing something blindingly obvious?

If you are running out of battery you can not adjust brightness.
charge the battery and check it again.

Lock brightness levels?

I noticed everytime I swipe to check my notifications my brightness levels change forcing me to set them again. I don't like the auto brightness optiom so I wanted to know if there was an app that would lock the brightness levels
Not that I know of. There are widgets that let you toggle brightness options, but don't lock them there.
It sounds like your solution is to stop sliding your finger from left to right on the notification bar. That's what's changing your brightness. Just pull it straight down when you need it.
I may be misunderstanding the issue, but it sounds like the power saving setting under settings> sound and display. The option is at the bottom by tv out. Alternatively turn off auto brightness (assuming you haven't already.)
Edit: there's also a brightness setting in the browser (menu> more> brightness setting)

It seems that TouchWiz has a brightness toggle built into the notification bar. If you just barely pull down, then slide sideways, you change the brightness. Just pull down faster and/or straighter to avoid it.

Auto brightness in 2.1

It's either missing for me or I can't find it after updating to 2.1. Any ideas?
They removed it.
My first suggestion would be to use the search function on the forum...

You know, I've seen a million posts just on this forum that say "Auto Brightness is now in the widget" and "Auto Brightness is always on" and now you're the first saying it's gone.

Because if you actually use the widget you will see it isn't "auto" its preset. Off Mid Full.
From what I can see, especially when using outdoors, the brightness level you set in "settings" determines the minimum brightness level.
Whereas, the actual brightness level is equal or higher than the minimum dependent on background light intensity.
Try to test it under sunlight, cover the light sensor then uncover it, should work.
Auto brightness is present. Its on the widget with your wifi settings. The brightness widget has three settings low, auto and high. I have tested it several times and the phone does respond to light and does get brighter. It seems they changed the sense algorithm for it. But it works, just not like it used to.
EDIT:
Here's a quick way to test, if you have desk lamp that's florescent you can set the widget to the the auto setting (second option). Unlock the phone and hold it up close to the light, if done correctly you can even see the text on the phone get gradually brighter. Now quickly cover the sensor and you will see it dim. You can use direct sunlight as well in the same idea.

Exactly. In the auto setting, you can adjust the maximum level in the settings, like it used to work.
To all those saying it's gone:
PUT IT UNDER A LIGHT! It's not that hard to see for yourself
Use the widget, set it so there is no green bar under the brightness, then press it once.. it will then get brighter on its own in bright light

[Q] Is my display losing brightness? Or is it a bad app?

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
Sent from my SAMSUNG-SGH-I717 using XDA
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.

[Q] Display current screen brightness

Is there a way to show the current display brightness set by Android's "auto" brightness?
I'd like to analyze sometimes in what level it's being set by the light sensor so I could consider controlling manually.
Sometimes it's just too high for the ambient, and could be using less battery.
I tried some apps on Google Play, like Brightness Motion, that show current screen brightness on widget or status bar but when in auto mode they'll only display "auto" instead of the percentage.

Have you tried this one? And here's another one.
Let us know if you find something that works.

The screen is way too bright and there's no way to adjust it when outdoors

So when you're outdoors, even if it's overcast there's no way to slide the brightness down (It auto-snaps to full brightness) even though it's not needed.
I have situations where i could easily use half brightness but my phone forces auto max light
YES, I know i can disable auto brightness completely, but that would not be convenient.
Any fix for this?
I use an app called Lux. Tons of options with it.

It doesn't actually lower the brightness some sort of overlay , no?

Hmmmm, Im not sure how it works but it does have an auto mode which you can tweak on the fly.
I have noticed that also. It also jacks up the contrast to make it easier to see.
It makes pics you took look terrible when viewing them outside. I had to learn to NOT delete them until I check them indoors. I assumed some pics I took were crap at first, but it was just the jacked screen contrast that made them look bad.
On my S9+ in bright sunlight it happens that not only something happens to the contrast and colors (eg. reds become somewhat pinkish) but also black elements on screen start flickering/smudging while scrolling. It looks like the device turns into some sort of brightness boost mode.
Does anyone else experience anything like that?

That's exactly what happens to me. Also if you slide the screen you can see how it the colors are totally distorted.

Check out the screenshot. There's an option to enable brightness slider in the notification bar. Becomes easier to adjust brightness just by sliding down the notification bar.

Did you read what the problem is? outdoors it snaps to max no matter what. (Unless not in auto mode)
Any solution for this problem?
Turn off auto brightness when outdoors..
Guys I've noticed that even if you turn off auto brightness go out in the sun and turn the screen up to max manually,it will kick up into super brightness mode or shine a led light at the sensor when indoors simulating the sun,just like it does with auto brightness on.sammy really want us to get burn in I think so we have to buy new screens all the time?

Never had a screen burn in on a Samsung phone. Don't worry
Guys, idk if this is a S10 only feature (or Android Pie), but when I'm on that situation, if I lower the brightness slider and leave it there for a second or two, the brightness will actually stay down and not jump back up again. Worth a try.

After the S9+'s update to Pie some of the old settings get copied to the new OS, but if you don't go into the settings and check, things might not be configured correctly - I had to choose a different setting and then choose again what was previously selected to ensure that it was written into the Settings correctly.
With the new update the "Automatic Brightness" applies to the AOD - see here in this screenshot, my search of the Settings for the word "auto brightness", see what comes up in attachment #1.
What you need to do is go to the "Adaptive Brightness" and turn it on, then manually adjust your brightness under a few different conditions (EG: Indoors lights off, outside and overcast, and bright sunny day). Now your phone will understand what setting you want for different conditions and automatically adjust the brightness based on lighting conditions, see attachment #2.
The "auto brightness" is now used for the AOD, and has nothing to do with brightness when unlocked. The reason it "auto snaps to full brightness" is likely because previous settings were just copied over after the update and you haven't setup (and trained) the new "Adaptive Brightness" for various light levels. The AOD has both "Auto Brightness" and double-tap the clock to adjust AOD brightness.
