Setting to disable dimming on white screens?

So the Lumia 900 dims the screen based on white pixel percentage (for battery) like the Focus and Focus S. Is there an extra settings option to disable this like on the Focus S?

What I'm asking is if there is an 'Extra Settings' category in the settings menu with a field called auto display intensity (like on the Focus S). Thanks.

I'm not seeing it. Today starts my 30-day trial to see if it can pull me away from my investment into Android and my HTC Desire..

I think you can just turn off the Auto brightness. There are no other display settings like on the Samsung WP7's

Yeah, the screen looks a little dim on the auto setting. Someone said that is the way AMOLED screens are. When you disable the auto and change the setting to high, it looks great. I just wonder what the effect on the battery life will be.

I recommend disabling auto-brightness and setting to medium. I personally use low indoors and medium outside. Auto-brightness should be off to save power.

The original poster is correct. Even on Bright with auto turned off, the message area is grey'ish, but white everywhere else seems fine. I went and tested it with the Focus Flash, and it had the same behavior, except when you turn off the "auto display intensity" (or words to that effect) it goes white. I think the Nokia has the exact same behavior, except that we don't have a control to turn it off. I'm keeping my screen on bright to alleviate this, and I know it's hurting the battery to do so.

Auto brightness = dims based only on the ambient light sensor. Auto display intensity = dims based on % of white pixels on the screen.

Do you know of a way to switch the Auto Display Intensity?

Is there a fix to this? I got my Lumia today and when I opened the browser and loaded Google it seemed very dim. Even if you change the background of the phone to white instead of black, it looks almost grey and dimmer than some of the other whites on the phone. Is it a bug? Should I replace the phone for another one, or are they all like this?

"Feature" not a bug. Samsung presumably provides Nokia the AMOLED panel which has it programmed into the firmware. Samsung modified WP7 on the Focus S to let you disable it.

Brightness reduced when some apps launched

With auto-brightness turned off and brightness turned up all the way, I am seeing the brightness go down when some apps are launched and turn back up when the app is closed. I noticed this today when launching GoChat and then also saw it when launching the stock jellybean web browser. I am not sure but I think this has only been happening since the last software update (T-Mobile USA).
I wonder if others are noticing this.

Saw the same thing when I launched camera app, I am on the latest update.
One difference is that I'm on auto bright and the brightness never came back

From DisplayMate:
Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.​From Samsung:
Samsung Adapt Display: The Galaxy S4 "learns" what you are viewing and adjusts the display's brightness accordingly. If the phone senses you are reading an article, for example, it will illuminate from a more muted brightness.​

Well, I have auto-brightness, auto adjust screen tone and power saver ALL TURNED OFF, but this 'feature' persists... and as I said, this is not just during web browsing, this is also during messaging with a 3rd party app, namely GoChat, with black background theme.... this is just not a smart feature.

maybe this is taken care of in the new update. i haven't unpacked it just yet. hoping to do that over the weekend or maybe even tonight.

What you're describing sounds like how Adapt Display is supposed to work. Does the display act any differently when you enable Adapt Display?

I have the same issue. Turned everything off completely and it still happens. I posted about a week ago and some people were having the same issue.
Some people said it was adapt display on, but I have it off. Once I switched to.the CM10.1 the issue went away. I switched back to wicked Rom and I'm still getting the same problem.
Maybe a dev will eventually figure it out while building a Rom

It seems like this is a feature that cannot be disabled by the end user. This is from Anandtech's review
"On the brightness front, the SGS4 includes dynamic contrast functions that cannot be disabled and change as a function of what is being displayed. There's an "auto adjust screen tone" checkbox under display but don't let that fool you, that doesn't disable dynamic contrast, just white point."

If it really annoys you, you can always try rooting it and install CM10. I'll be a drastic change but at least you wont have to deal with Samsung's bloat

Occasional Color temperature / screen tint change

Has anyone noticed their screen occasionally looking slightly warmer (more yellow) than usual? Not sure if it's after the recent update or if its always been there..i think its the update.
SM-960F here
Display mode - Adaptive. But I'm comparing just the notification shade.

That is probably a result of the blue light filter. It turns on automatically at 7 pm. You can change its settings in display

Thanks for your reply but its not that. I checked.

Do you notice it in certain apps? There's also a "video enhancer" feature under "Advanced features" - try turning that off to see if it changes anything.
The one other way I notice the screen temperature change is in bright light - under Brightness, you can control the "screen mode" - adaptive is default, which means it automatically switches between cool and warm depending on what you're doing and where you are (in the sun, for example). Take a look at the settings there, because you can customize it a lot.
Edit: I see you said you are on adaptive, so you probably already looked at these. Have you tried making it a set setting rather than adaptive?

Try turning off auto brightness.

Redmi Note 5 AI auto brightness doesn't work after 9.0 PEI update

Hey guys, I wanted to ask you guys, what is the problem with my Redmi Note 5 AI/Pro after Android 9 update?
I have a rare problem with my Redmi Note 5 AI/Pro/Globle version. The problem is that, my device does not adjust it's screen brightness even it's set to auto brightness control. And the peculiarly is that it goes down automatically if i adjust it to higher level and auto brightness is active but it does not come up even if I go to eclipse.

Mine works but it's still way too dim and reduces automatically after a while even if I force it brighter manually. I thinks it's related to pie adaptive brightness which can't be turned off in miui currently.
There's a magisk module (miui auto brightness) that helps a bit - it limits how dark the phone gets but the behavior is the same.
I've seen more than a couple bug reports related to that on miui forums, maybe they'll fix it.

Same here, have to do it manually.

Auto brightness works fine (brightness slider moving slowly but brightness adjustment is as expected in auto brightness mode)

Android Pie use a different algorithm to adjust brightness, it now encourage you on manual adjust the brightness yourself and AI will try to learn it instead of the old traditional sensor brightness.

Well I don't know what Google did with adoptive brightness or ambiant display but my Redmi Note 5 is just not working with this new feature and I don't know how to go back on to my older settings. This only forces me to every time go and adjust my display brightness manually. The worst thing is that i have to adjust brightness in the bright day light, like when i come out from a dark place and i just want to check any update I can't see my screen at all until I adjust the brightness to up. And to my surprise, sometimes when I scroll down the brightness bar to adjust it to an upper level I can see the bar is on the highest level but screen brightness has been lower from somewhere else, which I can't understand.

Somebody give me any good reason for Xiaomi's new auto screen brightness control system on Xiaomi Redmi Note 5 AI after PEI update, why should I have it on my mobile when I have to adjust the screen brightness manually every time I want to check my mobile for anything. Either it's on #Xiaomi's part or #Google's but I don't want it on my device.

I can confirm that, with the 10.3.1.0.PEIMIXM rom the auto brightness function not working properly, it's horrible!

Question Adaptive Brightness - Disable maximized "Sunlight Mode"?

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.
