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."
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/8
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

Adaptive Brightness Issues

With adaptive brightness on my screen frequently (every 20 seconds or so) changes brightness slightly even when the ambient light isn't changing. It's very annoying when reading and most noticeable with light backgrounds.
Is this a common issue or does it sound like I have a defective sensor?

Same here.
So annoying I had to turn adaptive off.
Seems to be when I move, probably changing sensor and it's too sensitive. My head mush change/reflect light on sensor
Anyway it's so distracting that I can't use adaptive brightness, except when pitch dark I can set to 0% adaptive to have lowest light output

Yep, reminds me of a disco strobe light!

No issues here. I actually think the brightness swing is much better than the OG Pixel XL. I can just leave the setting at 50%. On the OG XL I'd have to turn the brightness down in the living room with lighting from 1 lamp and a tv because it'd be burning my retinas.

I installed Lux Dash and disabled "adaptive brightness" and let Lux handle it. You can go into the profile editor for Lux and setup different presets for different levels of light, you can also adjust the min and max allowed brightness and even setup how you want it to adjust brightness (fade, only set on unlock, dynamic, etc)
It has really made this screen amazing and even helps with battery because most the day my screen doesn't go above 15-20%

I've been fine here with the Adaptive Brightness too. Doesn't change too often at all for me.
Sent from my Pixel 2 XL using Tapatalk

I installed Lux also and that did the trick. I assume the sensor is fine since Lux uses it with no problem. It's odd that some of us are having problems and others aren't but it doesn't seem to be a sensor issue.

Having this same issue any solution?

I'm curious but how exactly is it reacting for you? Are you just sitting in bed with the lights on and it's still adjusting up and down the brightness? Cause that's what I'm doing right now and it hasn't fluctuated at all. If I put it on the bedside table it'll brighten up and when I pick it up it dims but that's it.
Sent from my Pixel 2 XL using Tapatalk

Yeah that's too much fluctuations don't you think I mean on my iPhone x or any other iPhone that I have have used so far I never could tell that the adaptive brightness was on but this device does it in an obvious way and way too frequently that im not sure anymore if this is what it's supposed to do I chatted with a Google agent and they forced quit ambient service thing from system apps and I think that still didn't resolve the issue. I will pop up in a vz store tomorrow and check out if their display devices are doing the same

I'm curious to hear what the tell you. Lux has helped me a lot bit I still notice it. To be fair I think I only notice in a dim or dark room with the TV on but this is the first phone I've used where it's noticeable to me. I'm also wondering if this is how it's supposed to work or if there's something wrong with my phone.

What I described was too much? Sounds appropriate to me. If there's extra light on the phone, I want it to get brighter. If that light goes away, I want it to get dimmer. Now if it was happening with no light changing then I would be annoyed. I keep it at 29% with Adaptive Brightness on and it's not too dark in outside light and not too bright in pitch dark.

I'm having the same issue. I'm on my second Pixel 2 XL so I don't think it's a sensor problem. I only notice it in lower lighting but it's really annoying when it happens. Haven't seen this issue on any other phone. Im trying out Lux now and set it to only adjust when waking up. There were similar issues when Lux was set to Dynamic.

Ever since Google thought they knew better than everyone else and got rid of auto brightness for adaptive brightness, it's been trash for me. I CONSTANTLY have to raise it in dark rooms and lower it in bright rooms. AKA, I might as well turn it off because I'm manually adjusting it every time anyway.
All in all, it's terrible.

You know Adaptive Brightness is a mix of manual and auto brightness right? I remember auto brightness actually having the issues you're describing because there was no way to adjust it if it was set. If you have Adaptive Brightness on high enough, it should be bright enough in dark and bright situations. I believe people's issues are that it adjusts too often or the opposite, it's too dark in light rooms and too bright in dark rooms.

Yeah I know it's supposed to be a mix somewhat. It's supposed to match the setting you set to whatever the surrounding brightness is relative to your brightness setting.
That's exactly WHY it's trash in my opinion though. It's a flawed methodology. I don't want it matching my setting relative to anything. I want it low in the dark and bright in bright rooms or the sun to be legible and not more. It tries to do some meet-you-in-the-middle garbage and it just doesn't work well.

I found the threshold for the lowest brightness in pitch dark with Adaptive Brightness on to be 29%. That should be dark enough in dark rooms and outdoors it's readable to me. What percentages have you been trying?

Mines doing the same thing. Did anyone work out whether it was hardware?
I used a sensor app to see what light was reporting, and it was stable. I can only assume it's a bug.
For those who aren't sure - if the screen is on, and not moving, without any changes to ambient or direct light, every 20 or so seconds the screen will dim to a warmer colour, and then 20 seconds later will brighten to a whiter colour.

Yeah I had a feeling that's what people might be experiencing.

To add on to this thread, this is also occuring on my gen 1 Pixel.
Ever since I upgraded to 8.1 the adaptive display will brighten/darken while the phone is sitting still in a constantly lit room.
I also appear to have lost much of the granularity in the brightness selecting bar. The first 25% or so is as dim as it goes, and only after that does it begin to alter the brightness. Previously it would begin around 10% on the bar.
Additionally, the logic behind adaptive brightness seems to have gotten worse. I previously left my brightness setting always in the same place, and no matter where I was it was either dim enough (at night) or bright enough (during the day).
Real unhappy with this update.

brightness issue

Hi everyone. I haven't seen the related kinds of thread so I decided to post it. My device model is G3223.
tl;dr: It's too bright at minimum brightness during nighttime.
So during daytime the screen looks perfectly fine, no problem reading under the sunlight. But when night comes the problem arises because the phone can't go dimer, which means that the phone is still quite bright compare to my other devices when I am trying to read in bed even though the brightness is set at minimum.
Does anyone also facing this issue? Or if it's device model related?

I have the G3221 and I have the same issues. But I found 2 solutions to the problem. (well kind of) if you disable automatic brightness ? setting it will be way too bright. After enabling the auto brightness you can lower it even further. But if it still feels too bright, you can change the white balance settings to 255 which will lower the brightness even further without actually affecting anything. I hope it helps a little. ?

Problem solved. Thanks a lot. I don't know why Sony doesn't allow us to change the brightness to the real minimum point without using automatic brightness.
For white balance I set my phone to a warm colour. For (255,255,255) [r,g,b] the screen looks too cold though, and it can also lower the brightness. I am currently using (255,147,0) so it's at least better than the original setting (0,0,0)

Speaking of warm tones, sony also hides the blue light filter in the actions section which is almost invisible and many people don't even go there. You cannot enable it otherwise. They need work on their stuff.

You can use the Twilight app to use the phone at night without stressing your eyes. It works for me when I'm reading things. ?
And of course you can use this to lower the intensity of the screen's light if not the overall brightness.
Hope this helps.

Thanks for your advice. As far as I know, apps such as twilight only draw an overlay on the screen, which means it actually doesn't affect the brightness in any ways. It just seems to be darker.
In contrast, decron04's solution can actually decrease the brightness. Don't know why Sony doesn't allow users to minimize brightness without using auto brightness.

Setting Always On Display - How?

Clock... etc... on AOD I see wrong. There is little brightness. Both when. Sometimes small brightness, sometimes more brightness. Why? My Adaptive Brightness is Off ...
On YouTube video, I can see (Galaxy S9) settings (brightness) by tapping the clock. It doesn't work for me. I have a new "A50" and I don't like this.
Do you know an application that solves this (brightness, font size)?
Thanks a lot...
(Samsung Galaxy A50, SM-A505FN/DS, A505FNXXU1ASBG/A505FNOXM1ASBG/A505FXXU1ASBB)

I am not sure but you understand it in the wrong way.
AOD may be set in 2 modes:
-always on
-on upon screen tap ( so maybe this is what you saw on S9 video)
There is no setting how bright it is - just factory default
BTW if you could set the brightness up it will eat battery like hell

Yes-I have the "show always " mode turned on. On YT video I see "Brightness adjustment". I do not see this function on "A50"... Apparently I have a different version of "AOD ".
EDIT: + The clock color sometimes changes spontaneously. And the brightness is sometimes smaller, at other times the brightness is larger...
EDIT2: I Found that in daylight AOD shines a lot. There is little light In the darkness. This dependency cannot be manually set. Never mind. That's O.K.

I just got the A50 and have the same issues. The always on display - when set to "show always" is bright enough when in a well lit area, but when theres not enough light its too dim. It changes brightness level automatically. I have the adaptive brightness turned off. I have tried various setting and still the same result. I have the S10e and there is a setting to adjust the brightness level on the AOD, but it appears to be absent on my A50. I have also noted that the latest version on my A50 (AOD) is 4.2.51.3 and on my s10e it is 5.1.38.3. Should it be the same on both devices ? Any advice would be appreciated.

AOD uses adaptive brightness but its frequency is a lot less than normal usage.

I'm quite sure that is the intended behaviour for the AOD (automatic color and brightness changes throughout the day) to avoid burning the AMOLED panel.
In fact, even though modern OLED displays have improved its durability a lot, it's still not recommended to keep the screen on at all times in the same spot, especially under the sun.

Can anyone tell me the latest version of their AOD on the A50 - it is under settings under AOD - About Always On Display - that will tell you the latest version installed.
