Hello all,
I'm just curious as to how this feature is supposed to work. I have my device set to automatically adjust while it's on medium brightness and I've noticed that the brightness jumps from low to medium frequently, especially when I'm on just one page.

I believe it just counts the number of white pixels on the screen on the omnia. this is why it jumps so much. The only way to prevent the jumping is to set the birghtness on low, with the auto setting off. Even on medium or high it jumps when the page has a certain % of white pixels. Like for opening the browser its really annoying however on low brightness the colours are really nice and its just perfect for me. Its just too bright on med or high brightness for my preferences.
But the way how the "feature" itself work I have no clue. Maybe a light sensor. But the jumpiness is caused by the number of white pixels on the amoled screens, and occurs only on samsung devices I believe.

Thanks for that explanation, Marvin
Under display settings, there's this "Auto Adjust Screen Tone" that confuses me. Looking for the explanation as for what it does, I found it supposedly plays with the screen brightness based on the on-screen image, but it's very vague. What's the point of having both this and auto brightness? How do they work together?
Setting it on and off shows absolutely no difference. Does it really save battery at all?
Doesnt really do much for me either. I think its for a better accurate brightness level when you turn on auto brightness. When you turn on auto brightness and the adjust screen tone I think that would mean that the auto brightness would adjust its brightness by the sensor next to the front camera and the auto adjust screen tone would adjust to the image being displayed makeing the brightness best for the envrioment your in(how much light is in your room). Lets say your in a dark room and your trying to veiw a dark image, so the screen would get brighter even if the sensor is saying "theres no light here" based on the screens image. Thats my guess and someone correct me if im wrong. Idk if it saves battery but I just adjust my screen brightness manually.
It should actually be an attempt to match the color temperature of the screen to your environment. For example if you're outside it'll shift everything more blue (around 5,500 degrees kelvin) than if you're indoors with a "warm white" lamp lighting the room (closer to 3,200 kelvin). All this in an attempt to make colors appear more accurate wherever you are. It's safe to assume it uses the camera to read the colors of your environment, I'm pretty sure the light level sensor only measures luminance (brightness). Hope this helps.

^^^ that's what you'd think from the name, but if you read the description it says adjust display brightness based on image on screen to save battery. So I think for example if you have a mostly white screen it'll reduce the brightness. If done right, you won't notice it because it'll still look plenty bright.
Has nothing to do with temperature. I wish there were a feature for that.
I'd try it for a while to see how it feels. Probably a good feature.
This is my first AMOLED screen phone and something I think I may be noticing that maybe you guys can help confirm or deny about AMOLEDs vs LCDs, is that at night when turning the brightness down (way down, like -50 in the Lux Dash app as an example) results in getting the screen to a point where not bright enough to hurt your eyes at all but the blacks are too dark. So there's no real ideal brightness setting in a dark room that equals no eye pain but still allows you to able to see everything on the screen. Or are my eyes just too sensitive and most other people don't need to turn it down as much as I do and therefore don't have this problem?
You tried night mode
Lux is garbage. Factory adaptive brightness and still being able to use the brightness slider to allow on-the-fly adjustments is far superior - it works perfectly on this phone. And in a pitch black room, with adaptive brightness, setting the slider from 0-25% results in an extremely dim screen (1-2 nits) will information still perfectly viewable. Blacks may have uniformity issues, but that is the nature of OLED panels since it is extremely hard to control voltage at near-black levels when the brightness is extremely low.

Amoled displays, when used with automatic brightness adjustment, have a small problem - when you are viewing them in the dark, they appear too dark. Their contrast ratio is infinity, which means that dark colors are basically zero luminosity or close to zero. A lot of internet imagery is calibrated for lcd displays, so when you lower your phone brightness to make the brightest parts viewable on an amoled display, the dark colors become too dark and blend together. This is especially true when you are viewing a screen in a dark environment. There's nothing you can do but increase device brightness by hand when you are using automatic brightness adjustment and viewing in the dark,

You do realize that Adaptive Brightness simply changes the brightness of the screen in response to the light sensor reading?
In other words, the phone doesn't care about your preference - it will change the brightness to preset levels.
On Samsung phones, this situation is far more intelligent. The phone still uses the light sensor to adjust the brightness, but the phone also applies a user preset to augment the brightness - when you slide the brightness slider up, the phone will make auto brightness adjustment higher, and vise versa.

WHAT? You have it totally backwards. Stock Android, including the Pixel, uses user input to augment the auto light sensor brightness when adaptive brightness is enabled. If my phone thinks 50% brightness is appropriate, but my slider is set to 100, it will choose something like 75% brightness instead. If I drop the slider to 0% in the same instance, it might choose 25% instead. The user preference will ALWAYS be impacting auto brightness.
Samsung phones, unless it changed with Nougat, rely strictly on what the phone thinks is best for auto brightness. The user can adjust the slider with auto brightness on, but the slider is a direct adjustment 0-100% of the true brightness level, and the slider will change automatically when there is a large shift in ambient light after the display has been turned off at least once. User preference does NOT impact auto brightness unless you set it at that specific moment.

Girl, are you kidding me? I just returned a Note 7 for Pixel XL. What were your phones?

I have a Note7, Pixel XL, and LG V20. Google how adaptive brightness works. There won't be a single article that matches how you say it works.

Give me evidence. I don't care what your hypothetical "articles" say, I had the actual phones and played with their brightness settings.

If you seriously can't tell how adaptive brightness works just by using it as compared to Samsung and LG, I don't know what to tell you. It's pretty damn obvious. If I'm the kind of person who prefers a bright screen, I can set adaptive brightness to 100% and it will always be bright, but stay relative to the ambient lighting. If it's a dim room, the screen will be bright, but nowhere near 100% manual brightness. It only hits 100% manual brightness when under bright light like the sun.
Samsung's auto brightness is still very cookie cutter. If you put 2 Samsung phones side by side with auto brightness on, they will always be the same no matter the ambient light. If I take 2 Pixels, both set to adaptive, and put one on 25% and one in 75%, they will always maintain a brightness difference even when ambient light changes. Samsung phones do not maintain user preferences once the ambient light level changes. I almost never have to adjust my Pixel. I always have to adjust my Note7 because I prefer a slightly brighter screen.

What you are saying is EXACTLY THE OPPOSITE of my experience with Note 7 and Pixel XL. I NEVER had to adjust my Note 7 brightness once I set it.
I find myself constantly adjusting Pixel XL brightness setting.
Maybe they both have "adaptive brightness", but the Note 7 version was perfect, and the Pixel XL is just sh`1rt.

Or maybe you two just have differing opinions on what a "perfect" brightness setting is...
Doesn't matter how you adjust your brightness. I'm just saying that when brightness is low, blacks are darker and disproportionate to other colors.
I love Lux especially with it's profiles. Much better control and accuracy than adaptive brightness. I just wish Lux had an auto-profile switcher based on time of day. I have a day profile, night profile, and car profile.
One thing to note is that Lux allows me to bring the darkness down below 0% to negative values, which is where I usually notice my concerns. But that's what I need to not hurt my eyes at night. So I don't blame the phone or anything - just posted this article out of curiosity. The blacks are probably just turning off completely at some point when I bring the value to below 0% which I think makes sense based on the nature of OLED.
You should just turn on night mode to help with eye strain. If 0% brightness is too bright I don't think you will ever get lux to work the way you want, but night mode helps my eyes a lot.
Pixel XL adaptive brightness adapts to what you set the brightness to. If you go from 0 to 100 in a totally dark room, you notice how the screen stays really bright and doesn't go back to 0 on Pix
Many phones use auto brightness to fullly determine brightness based on sensor and ignores user brightness. If you go from 0 to 100 with an auto brightness phone, the phone will go back to 0.
Some prefer one over the other.
Have you guys noticed that when you turn adaptive brightness off and slide the brightness slider up and down the screen temperature changes color?? This is happening on 4 pixel 2 xl that I have seen including mine...so strange. It is especially noticable on a white background. Is this only me?
edit: You can also see this with adaptive brightness on and when it ramps the brightness up and down, the color temperature changes with it.
I've noticed it while using the phone on the train, as the lighting changes, the temperature of the screen changes between warmer (more pink) to cooler (more blue/green). It doesn't last long and I assumed it's because of the adaptive brightness.
