Hello!
I bought a Base S22 a few weeks ago and so far, I'm loving this device. But one thing that bothers me is the adaptive brightness implementation from Samsung, because its not really "adaptive". Even on some cloudy days, the brightness gets maximized and I can not change it to a lower level, because I always get the "maximized for best viewing in bright light" notification. In all other scenarios the adaptive brightness algorithm works perfectly.
Is there a way to disable this kind of behavior?
My current solution for sunny days is a Bixby routine to quickly disable adaptive brightness when I'm longer outside to save some battery.
Use manual brightness control. Adaptive brightness never worked right... no surprise it still doesn't.
You can manually lower the brightness even in adaptive mode, and hopefully it will adapt to you too.
Another options are:
- Battery Saving mode has optional "10% lower brightness "
– Battery Guardian module of Good Lock (with dependencies!) may be configured to lower brightness when phone's temperature is high

That never works right either... The only draw back to full manual is finding the slider in bright light to jack it up. Auto is easier to temporarily use then. That said using the device in direct sunlight should be limited to seconds not minutes. Avoid whenever possible.
50% or less is best for battery and AMOLED conservation.
Using manual brightness control saves battery, display and your retinas

The problem is that the phone puts the brightness to the maximum and locks it there in bright light. Even when I use battery saving to lower the brightness by about 10%, it doesn't let me change the brightness to a lower level.
I don't know if this is just a thing on Samsung phones, because I heard that they use the adaptive brightness algorithm with KI from Google.

Which is why I use full manual control almost always. Invariably auto is many time too bright and has a tendency to "jump" around. Lol, human vision in much more adaptable and its nearly seamless.
The brightest stars burn the quickest... my plan is to have a display that's perfect for the life of my heavily used devices which likely will be in excess of 4+ years. Batteries are easy and cheap to replace, the displays aren't. Samsung's plan is to sell you a new phone every year.

I used to have it at 100% now doing 50%. does it really affect battery?
Adjusting the brightness in general does affect battery life. Although I'm not sure how much adjusting the %, while still using the "Auto" feature will work out. My thought on adjusting the % (while still using Auto) is not so much about battery life, but rather to have some more customization on how bright you like the screen. Many folks will criticize that Auto brightness algorithms are often insufficient and too bright or too dark for the given situations.
If battery life is your concern, I would suggest ditching "Auto" altogether. Reason being, being on Auto constantly polls the light sensor which in itself uses some battery
I haven't experimented with this phone, in particular. But on a previous device, I found anecdotally that turning off Auto and manually having it set to 40% brightness increased the battery life by around 30-40%. Of course, you mileage will vary, and it will depend on how you use your phone and other factors; as well as what brightness level you prefer.

I've always manually adjusted autobrightness and generally leave it set at around 40% and adjusting when I need to, which typically isnt a great deal each day. Very rarely go anywhere near 100% brightness. It may be worth experiementing and monitoring your battery life for auto and manual over say a week to see the results.
I was under the impression that the slider position was irrelevant if Auto was selected. So setting the slider on Auto sets the upper limit the algorithm uses?

Your second point seems to be the case, yes.
You will notice even if "Auto" is selected, moving the slider back and forth will make the screen dimmer/brighter for the given ambient lighting condition.
On older devices, your first point was true. Selecting one would override the other. If I remember properly, manually selecting a brightness level would deselect the "Auto" feature.
My understanding has always been that the slider sets the MAX brightness the screen will go up to when set to auto. So if you put it on 50% and go outside in bright sunlight the screen will only go up to 50% which may not be enough. I set mine on 100% and that way if I am in direct sun the screen will go as high as it can and still go down as low as is needed when in a dark room. I will also say that of all the phones I have ever owned this one has the best auto brightness implementation of them all as a stock feature.

That's what I thought but it's the opposite! From HTC website: "With the*Automatic brightness*option selected, drag the slider to set the maximum brightness level.*This sets a LIMIT on how bright the screen will be when*Automatic brightness*is selected"
Source: http://www.htc.com/us/support/htc-one-m8/howto/465124.html
This means that it will only affect the lowest brightness level, not the highest, meaning you can have it a 0% and it will always go to maximum brightness when in direct sunlight. I've tested this and can confirm it's empirically true.
I've seen a couple posts about delays with adaptive brightness, but this is a different item. I'm seeing that the adaptive brightness alters the brightness a little too dramatically. In a somewhat dark room (not pitch black) the brightness will be at absolute minimum even when the brightness is about 1/3 up on the slider. In a moderately bright room that same brightness setting will be near maximum.
Does anyone else notice this as an issue? I'm just wondering if it's normal (ie, software calibration issue) or if the brightness sensor might not be seated correctly.
It's normal. Or at least it sounds like it is working the same way mine is. And yes, IMO it is a little too sensitive. The Lux app works beautifully if you want an alternative. Also, the goog is known for tweaking this feature over time with updates.
I've noticed this too. The biggest thing for me is walking down the street at dusk (so not dark out yet) I can't read the screen as it turns it all the way down, then, when I walk under a street light, it turns it all the way up to full! It's one extreme or the other, there seems to be no middle ground.
In other words "adaptive brightness has mind of its own!"
This is why I have always kept this setting off. The brightness just changing on its own always annoyed me.
When it works properly (and it should) for ones uses, it's great, it's automatic, what's not to like? It's a pita to always have to change brightness manually just to see a phone display depending on ambient lighting which varies immensely for many users.

I agree. I have it set to maybe around 15-20% (centered over the WiFi symbol below it) and I never need to touch it. Gets dark enough for night driving and bright enough to read outside. Never found it stuck on one or the other when it shouldn't be.

If you buy the app Lux you can customize how it adapts your brightness. The free version is good to but you have to use mostly default settings. By default it only adapts brightness when the screen turns on.
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.

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.

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.
hey guys,
im having trouble with adaptive brightness since some time and i am pretty sure sth has changed there.
my screen is just to dark for the most time.
some time ago i could just increase the brightness value and the adaptive brightness would work with that (higher) value, like an anchor value.
now, by doing that, i just change the overall brightness and it will jump back after some time.
is this the same for you guys? it gets obviously when being in a dark room and ramping up the brightness (with adaptive brightness enabled) to 100 percent. now when i disable adaptive brightness, exactly nothing changes in terms of brightness, however former times, there would be still an increase in brightness since 100 percent with adaptive brightness does not equal 100 percent on manual brightness (at least in a dark place). now it does.
is this the same for you? was this an update or sth?

also just tried another one, kikasura or how it is callled. same thing.
just that we are on the same page here: you still can increase the anchor value in brightness settings. or will it, too, just increase your overall brightness for a short time and as soon as lights change or you lock the screen it will be back to previous values?
I stop using auto brightness because some times he is crazy.
I prefer manual mod, like this I have the hand on it and i consum lot less battery (It's my feeling)
Adaptive Brightness is still working fine for me. The way I like to "calibrate" it is when in pitch dark, I set it all the way down to 0. From there it'll always go maximum when in sunlight and indoors it's somewhere in between and does fine. If that's not enough, try resetting adaptive brightness:

It is happening the same to me on very low light scenarios, auto brightness will go to the lower value, setting the screen without almost no bright, besides I put it manually higher. Maybe this happened after a update I dont know.

Hey guys,
So as well know, maximum brightness can only be achieved when "Adaptive Brightness" is turned on, for reason of battery usage, temperature, burning, etc...
As far as I understand, if I stand outside, in the most brightest of suns and set the manual brightness to max, once I'll activate Adaptive, the screen should get even brighter, as the situation requires it.
However, that doesn't seem to happen at all. Am I missing something? Did I not understand how this function works? Is my display just not as bright as the common note display?
Thank you!
I'm in blazing sun and toggle AB on off and screen goes to about 20% brightness ..... ??!??
