[Q] Automatic Brightness problem

A few days ago I started to use the Automatic Brightness, but it doesn't worked very well...
When I am in bright area , the brightness increases, but when I leave the area or cover the brightess sensor, the bright the screen should change his intensity, but he remains the same, at high brightness. The brightness decreases and becomes what it should be according to automatic mode only after lock-unlock screen.
Anyone can help me?

I think the sensor dont have problem.

I think if you check the option "Display -> Brightness -> shade bright screens" (or somethink similar to that, i have to translate) it could make it work properly. A broken brightness sensor doesn't control anything anymore, my old DHD had one.

i think its a software problem

Same problem on my razr i
But on some razr HD, there isthe same problem. Maybe the software version....
I use "custom auto brightness" apk on market, and work great for increase AND decrease brightness.

For information, same problem with JB 4.1.2 update...
Anyone have the same problem and a real solution ?

Thanks this app worked very fine!

Just use the app lux auto, my brightness sensor was working ok but it always too much bright wasting battery, after installing lux auto and understanding how it works i have to say its perfect now!

Is the pink tint on all devices or is it a defective screen issue?

Hi, I have noticed the pink tint to the screen when using adaptive brightness below 30-40% and was wondering if it effects all devices.
I have read a lot of people talking about it and that it happens because the screen goes so dark and some people are saying that it is supposed to happen. Is this true and if not is it effecting all devices?
I am on my 3rd device now the first one i took back after a few hours as the screen was tinted really yellow and uneven and my second one had image retention pretty bad and would happen after 5 seconds of the nav bar being displayed and i dont know if it effected them as i didnt try adaptive brightness as i didn't ha e them for long enough.
The one thing i find really weird though is that i have been using the lux app to test if it was to do with the phone going so dim and while there is a slight pink tint when putting the brightness down on the lux app it is no where near as bad as when adaptive brightness is being used and the lux app goes a lot darker.
Thanks.

I've seen all does it specially at night. I consider this is normal

Its because you're brightness is below 0. If you use adaptive brightness at night its lower than 0 without adaptive brightness. You will see the same thing if you use the lux brightness app.
Edit: I noticed you used the lux app, you're correct its not as bad with it, but it's still there. I could be a software implementation or a bug for all we know.

So it is actually on all devices and not a select few?
I got 7 days to return it for another one but if it is on all devices and there is nothing that can fix it i dont think there is no point in risking it for another nexus 6 that could have a worse screen like uneven colours.

This is more of a feature than a defect, frankly...
Not that it is pink, but that it can be dropped down as low as it can.
Basically, there is a minimum brightness threshold. The lower the brightness, the less power it consumes. If you set the brightness below a certain point, the colors (because of the nature of the amoled) will start to mess up a bit. Most vendors will set the minimum brightness high enough to not have this happen. Google sets it a bit lower to save a bit more power, without making the colors go *entirely* crazy by setting it WAY too low.

Its made like that to conserve power. All nexus 6 are like that

I thought it was a defect too until I started researching and like someone suggested turned off adaptive brightness which made the tint go away completely even at lowest brightness setting.

Adaptive brightness is actually a really nice feature.
If the pink bugs you too much, you can (if you know your way around a compiler, that is...) bump up the minimum a little.

What if adaptive brightness is off, and the brightness is set to at least 70%, and the pink tint crap still happens? kernel issue? nougat issue? Because it's very annoying, randomly happens to me. usually, going into twrp and clearing cache fixes it. sometimes it doesn't though.
Help.
EDIT
Never mind. I figured it out. it was night mode that was causing the pink tint via purenexus settings.

Outdoor Mode (hidden brightness menu, WHY?)

title says it all, why is this hidden and can only be accessed thru settings, and it's not a one time toggle, you'd have to go into settings every time you pull your phone out. just why? would be great for the brightness slider to just go to max instead. anyone know if theres any mods for this? or just what this is about, seems strange.

i dont have this mode
what android version u have

I cannot find this mode on my Exynos Note 8! Have you flashed another rom?

Mine always stays where ever put the slider. But then, I have auto brightness off.

Yeah what version you got? Wish we had outside mode.

I have a 950F exynos 128 GB, and It does not have such setting...

Because it's samsung. They will probably never make a good software. Just search for "automatic brightness bug". They just ignored this problem. No wonder they just hidding that option.
Outdoor mode can be enabled by editing something in system folder. Most of custom firmwares provides that function.

I've never seen that setting on mine. It's automatic for me.

IT is not a bug, and yes, there are ways to increase brightness beyond standard maximum, I remember from the days of my note 3, that many people posted very bad screen burn in and excesive batt drain when changing the lines to attain the most bright screen possible, same applies to speakers, might as well get blown, The auto brightness in note 8, in fact is very well implemented, because it learns your preferences, that is, if set to auto, and you move the slider, whenever the phone detects the same lux level, it will set the level you chose, infact, when in autobrightness, when sensing too much light, it will set an extra ammount of brightness

Agreed. Works very well. Was using GPS Google maps for the first time yesterday, screen was automatically too bright. I used slider to lower brightness, it learned my preference.

Since long I haven't seen any Note device (at least International versions) have Outdoor mode enabled by default unless you are using custom ROM. But this mode i have seen available on low range samsung devices. Actually it is hidden and one minor change in settings app enough to enable outdoor mode.
I will try to make small app without making changes in setting app, though it might needed root access.

Thank you dr ketan! I have used your excellent roms and kernels in my note 3 and 4

As I said y'day, I have made and posted Outdoor mode Tool on my Facebook wall.

hey something cool came out of this post, awesome!
so the app acts like a toggle to turn on the outdoor mode, pretty cool!

Works perfectly. Thank you.

Have noticed this mod seems to time out after 15 minutes or so. Any workaround for this?

@ dr.Ketan: since updating to oreo your app does not work anymore... do you have a solution?
THX in advance!

I am on oreo too and working fine. Check you have granted su permission

Intensity of screen colors in Android 9 Pie ???

Hello,
Perhaps it is only my perception, but after updating to the final version of Android 9 Pie, I notice how more "washed" the colors on the screen, it seems to me that in Oreo 8.1 the colors were more saturated, more vivid.
Where I first noticed, it was in the green of the WhatsApp icon, now I see it fainter.
Has anyone noticed this?
Regards!
PS: Sorry for my English!

Yes the colours aren't the brightest on Android Pie, also i noticed something wrong with the brightness, earlier the screen used to be bright enough even on 30% brightness now i always have to keep it above 40% during day time.

maybe this is due to the new battery technology IA

I don't see a difference except I feel like the intensity of the screen is a bit smoother. Yes it's not as bright but before the update when I put it from 10 to 30 there was a higher bump in brightness now its more regular. I don't use adaptive brightness because I like it to be fixed
Seems like a fix to me.
Didn't notice problem with color though

MIA2 updated to Pie and all colors have been dull and boring
After updating from Oreo to Pie my MIA2 phone has become dull and boring. The vivid colors have become silly and even the photos also got affected. The phone has lost it's brightness too. Even the red color of Quora has become dark brown. Can't understand whether this is the new phone on which I am working or it's like some old septia color version phone. It's really disgusting.

I hope they correct it soon, it was one of the characteristics that I liked most about A2, the most vivid colors. The A1 had weaker colors.
In 9.0 (10.0.1.0 and 10.0.2.0), the A2 is seen as the A1.

I recently bought an A2 and noticed the screen saturation on Android 8 to be unnaturally high, especially skin and lip tones. If I look at a regular photo on my PC, iPad or Huawei P9, colors seem OK, but on the A2, it seems as if the person is wearing lipstick for example. I haven't received the update yet, but if it reduces the saturation slightly, I will be more than happy.

Question Auto brightness too low

Hello, 3 days ago I bought oppo x3 pro. Phone is awesome, but auto brightness works very bad... It keep decreasing screen brightness to very low level.
I never seen something like that, Samsung S20 works much better, well, even realme x50 works normal. To use phone I had to disable auto brightness. Is there anything like adaptive screen brightness, I read somewhere that samsung by the time learn my preferences, and keep good brightness. Tired this with oppo for 3 days, but seems it doesn't have that option.

If it is the same mechanism as in OnePlus (not sure about it) - then the phone will "learn" after you manually set the brightness to proper level. Give it 2 weeks.
Btw. Rydzyk in avatar, hope youre not the real one

Real Tadeusz here
I was teaching for 3 days, but without success. Will try for a week now
thanks

Try clearing system cache and data in the relevant apks.
Test the light level sensor to see if it falls within an acceptable range.
I use manual brightness control almost always; doing so saves battery, retinas and sanity.
It also reminds you when it's too bright and your frying your display.

Same here. Helped me out with Lux Brightness and set the minimum brightness to 30. Works fine for me.

To me in Realme 8 it seems to have learn a minimum value for auto brightness instantly, I just set a minimum a little above of the default level (It was very low), and the phone remember that level onwards

well, mine surely isn't 'learning', it keeps defaulting to the lowest value, which is waaay to low.
Are there any alternatives to Lux Brightness that you know off?

What happens to me is that the default auto brightness deactivates itself when it wants, and reactivates also when it wants, very annoying. So I deactivated manually the auto brightness and tried Velis Auto Brightness, this app is a little complicated but works quite well, just you have first to understand the app itself and then tweak a little to your convenience. It has a little bug in Android 11, the notification of lux and % of brightness screen disappears after some time but doesn't affect the app itself.
