[POLL] Extreme auto color boost under the sun

Hello!
Some of you maybe have noticed that when the Galaxy S faces the sun, in auto-brightness mode, the color are suddenly boosted by a crazy amount in an attempt to preserve color saturation perception despite the incoming light.
Do you think this is a useful feature helping readability or does it do more harm than good ?
I can disable or tweak it very easily in Voodoo color. I have mixed feelings about this, that's why it's still on, but some people asked me to disable it.
I need your opinion and experience
Please don't vote if you don't understand what it is about and never experienced it.
Thanks !
Note: this color boost is associated only to the automatic 100% brightness level.

that is actually just brightness at 65% or higher
by default on regular operation when the brightness is set to auto it is always below 50% that's why people complain about colour being pale and such
if you set the brightness to 65% or more you can appreciate the full bloom effect of the SAMOLED screen vs AMOLED
i use a simple brightness widget to set it how i want, but it's mostly on auto, except when i want to WOW! people

@AllGamer we don't talk about the same thing.
It's not the standard brightness level, that's something that append only in the situation I described
If you are lucky enough to have a sunny day you can try it by yourself.
I didn't manage to reproduce it using artificial lights, seems that any light i have is not as bright as the sun ^^

i do use the phone outdoor almost on a daily basis, specially during lunch time when we walk to the restaurants meanwhile checking for emails, forums, weather, prices, another restaurant nearby, etc, etc.
so i've seen the screen colour/brightness changes in many different occassions.
unless there is another method to control the colour without controlling the brightness and vice versa, then i'm pretty sure i'm getting the same effects when i manually slide the brightness bar all the way to 100%, 85%, 75%, and 65%
anything less than 60% wont show the blooming colour effect

sorry @AllGamer, you don't get yet ^^
I don't know if you read the original post?
I can show you the source code in kernel if this is necessary.
This special color boost (really extreme color boost) appends:
In auto brightness mode
When it's bright enough to make the auto-brightness mode reach the 100% level (named gamma 24)
When already at auto 100% and screen facing the sun.
Well, that's not so bad, it's just a poll

Here is the link to the source
http://github.com/project-voodoo/sa...nux-2.6.29/drivers/sensor/optical/gp2a.c#L329
Code:
if(autobrightness_mode)
{
if(current_gamma_value == 24)&&(level_state == LIGHT_LEVEL4)

So far I've only experienced that once in my 3 month old SGS. I usually use it indoors.
I think you can replicate that by ticking Outdoor Visibility in the camera app.

Seen it alot of times, It does seem to help quite well, So i say keep it

yeah, that is what i call the colour blooming effect, just like in the PC blooming effect on the video cards

Absolutely! the Outdoor mode in Camera and Video apps are similar (but are triggered manually)

woops... just tried the Outdoor Visibility and it is not the same as what I experienced before. You really must be outside & under the bright sun. I'll try it again tomorrow.

it just does it to the entire screen but stronger, there is an widget to control screen modes and it can be toggled manually when set to 100%

I pointed at the sensor with a 12LED flashlight (Need to be quite close for the blooming effect to activate, ~5-10cm), and it bloomed away after 3-5 seconds.
I've never been bothered by it and never really noticed it in bright light, so I would think it's a positive feature that helps readability in strong sunlight.

You cannot reach this mode with manual controls.
It depends on data measured by the light sensor, it's in kernel.

well i guess i'll have to install your Modifications, to see if there's really a difference
but from my point of view, when the level at set to 100% looks the same as when the phone is working outdoor under bright sunlight 12 noon lunch time.

It's in every standard kernel!
Ok, I give up ^^

I say keep it. It seems like it would be functional. Looking forward to the warmer colors at more brightness levels, as my phone very rarely runs at 100% brightness.
What I don't like (maybe others agree?) is the sudden drop in brightness at low ambient light levels (not complete darkness).
Thanks for your work on the color issue. This is really what I look forward most to in future voodoo releases!

well it'll definitely be nice to be able to access the bloom effect under low brightness level
i like more colours
i was under the impression supercurio was coding something to do that

Anything that makes the screen better in the sun is a good thing.
Even with the SAMOLED, things can sometimes be harder to see outside, especially while web browsing.
It doesn't matter if the colors are off in the pictures when you can't even read the web page.

Is it possible to make these sort of things configurable by an app on the phone?
Or must these sort of settings be hard-coded into the kernel?

Any fix for the brightness on the Nexus 4?

The auto-brightness on the N4 is too conservative - it's always lower than it should be, especially in outdoor conditions.
I've tried some apps (Velis, Lux Lite, and others) but they tend to flicker and have annoying notification icons (even when I disable them from All Apps).
Any suggestions?
*Giving Lux Lite + N4 Plugin another try, I believe I missed out on all its features the first time. Will post back tomorrow.

It's becoming a cliche for me to recommend this app, but if you are rooted, give Gravity Box for Xposed Framework a try.

Not sure why its lower for you outdoor. Auto brightness works for me outdoor.
There are couple tricks that works for me with nexus 4. When I am in home, I bring the brightness to 0%. Outdoor, I leave the brightness on auto. At night I use an app *screen filter* by haxor industry; its free and works great. You can bring the brightness to the lowest level as possible.

Wow that's crazy. I think my N4 is TOO bright. Even outdoors
Have you compared it to another N4?
Maybe faulty screen?

in your brightness setting doesn't it have the sensor sensitivity adjustment and adjust the values of brightness
paranoid android
I have notification toggle to configure the brightness if I need too, indoors at 0 and outdoors high as above
you don't have the screen protector over the sensor right?

s7 edge too dim at low setting vs note 4

Hello,
I decided to get the s7 edge... I had the htc 10 for less than 14 days and I was not really happy with the camera .
Anyway.. I still have my note 4.. and I don't use auto brightness.. I like to manually select my brightness.. usually lower than most people.
In Display settings I also have adaptive colors..
anway.. at the same level.. the s7 is very dim compared to my note 4.. is there a setting I am missing or something?
Here are two pictures showing the difference.

Just increase the brightness slider.
Different device doesn't have the same brightness at the same percentage.
S7 just have very wide range of brightness compare to other phone.
At lowest brightness S7 is dimmer than note 4 and at highest brightness S7 is also brighter than note 4.

I am not sure about the lowest settings but peak brightness is only achieved in auto setting. It is also recommended for battery optimization.
Personally I find the auto setting superb. It also has a learning function which over time will adapt to your preferences. Just keep adjusting it slightly to your liking in different situations and you'll get there.

Automatic brightness of OnePlus 6 was removed in OnePlus 6T?

According to this german article, the automatic high brightness mode (only achieved, when the phone is in bright sunlight) has been removed in OnePlus 6T, but is still available on OnePlus 6.
The biggest problem with this is, that the maximum brightness of the display can only be achieved by that automatic high brightness mode. This problem sets the maximum brightness of the OnePlus 6T to 431cd/m², for OnePlus 6 it was 607cd/m² (due to the automatic high brightness mode).
Can anyone confirm this? Do you think, that this will be changed in a future update or what could be the reason for this removement (maybe the indisplay fingerprint scanner?)? Especially this quote worries me:
There is now feedback from the manufacturer that makes it clear that the OnePlus 6T no longer has a High Brightness Mode

I translated the article into English:
OLED Display: OnePlus 6T no longer offers High Brightness Mode
Smartphones with OLED displays often limit the maximum brightness in order to reduce energy consumption and the load on the panel. Only the High Brightness Mode with automatic regulation enables the maximum. This was also the case with the OnePlus 6, but this mode is no longer available with the OnePlus 6T.
In the OnePlus 6T test, the display of the smartphone was praised predominantly by the editorial staff, but in terms of maximum brightness there was a step backwards compared to the OnePlus 6. Instead of up to 607 cd/m² of the OnePlus 6, only up to 431 cd/m² could be measured with the new OnePlus 6T.
OnePlus 6 glows 40 percent brighter in automatic mode
Although the OnePlus 6's display glows as brightly as the OnePlus 6T's using manual brightness control, a High Brightness Mode with automatic brightness control via the brightness sensor on the front of the smartphone makes the display a good 40 percent brighter.
With the OnePlus 6T, this particularly bright mode could not be activated even with the aid of a bright LED torch. Up to now, this measure had still illuminated every OLED display brightly, provided a corresponding mode was available. But this time without success.
OnePlus confirms measurement result
ComputerBase was sure at the time of the test that it had not measured an incorrect value, but nevertheless contacted OnePlus to find out whether the OnePlus 6T again had a High Brightness Mode, which simply could not be activated on the test device - for whatever reason. After a somewhat longer waiting period, there is now feedback from the manufacturer that makes it clear that the OnePlus 6T no longer has a High Brightness Mode. ComputerBase does not have a statement on the background to this decision.
The measured value determined in the test is therefore correct and to be regarded as final. Should OnePlus offer a new High Brightness Mode with a software upgrade in the future, the editors will re-examine the display of the OnePlus 6T.

Auto brightness is there just to the right of the slider.

Ok, that is strange. Do you have the latest oxygenos?
And why do they write, that OnePlus has confirmed, that it got removed? And what about their measurements?

Oxygen 9.0.5, I have no way to measure the brightness.

Do you mean high brightness mode, when the phone is in bright sunlight and gives it an extra boost? From the reports of the lower brightness I can only assume it's because of the fingerprint scanner, if the screen is on maximum brightness already then maybe it doesn't work properly as the sensor area can't light up brighter than the screen?

@__NBH__
Yes, that is the mode I meant with "automatic brightness mode". I chose the wrong words for that perhaps. It should be high brightness mode. I edited it in the main post, thank you.
Can anyone confirm, that this mode is disabled for the OnePlus 6T?

The high brightness [emoji364] mode was available with a distinct app, what is activated the high brightness mode in strong sunlight. I read it is not available anymore in the 6T. This High Brightness [emoji364] mode is available in some OLED phones. My OP 5T knows it after I downloaded and installed the app for it, what is activating it. You can turn it on manually or you can use it automatically, it turns on when there is strong sunlight. But it doesn't work on the 6T. It is damn sad. This is one of the disappointing things about the 6T. Fak

Yes but this isnt the same.
Auto high brightness boosts the screen in direct sunlight / high brightness areas.
HBM in kernel manager just forces the screen to be at max brightness at all times, ignoring the brightness slider. This is not a solution.

it is the same.
In order for Auto HBM to work the ROM/kernel needs to support HBM. Auto HBM is nothing more than an app or widget using HBM functionality.
The fact that HBM can be set in EXKM proves the ROM supports it, EXKM itself doesn't add it.
You can use Tasker to make HBM into auto HBM. But the discussion was did OP remove HBM from, they did not.

Nice to see ABC wiz at the 6T boards! Hello

Did anyone try, if it this method works to enable the high brightness mode for sunlight?
And do you need to root your phone for this?

[problem] Auto brightness, Screen too Dim?!

no problem under sunlight but in dark environments the screen is way too dark.. I barely can see what's on the screen.
any resolution?

Hi, same , Problem,. I stopp the automatic at night.

I have the opposite problem. I find myself constantly turning down the brightness in the early morning.

MIUI is full of AI. I'm taking a guess here, but instead of turning off auto brightness, try adjusting the brightness slider in cases when you find the auto setting uncomfortable and see if it learns your preferences with time. I think I only sometimes turn it up at night when it tries to save battery and go too dark. And sometimes during the day I'll turn it down if I have the notification shade open and it seems to me that the light can be dimmer. I'm pretty satisfied with the auto setting on this phone.
Btw (a new MIUI user here, this has apparently been a MIUI feature for quite a while), have you noticed that in harsh daylight not only will it turn up the brightness to max, but it will also bump up the shadows, saturation, all kinds of crazy stuff, like a "vivid" mode on TVs? See what I mean here.

yes it does pump up the contrast for better visibility

Brightness problem too low
Yes, i am facing same issue it dims the brightness too low in dark, i have to manually increase the brightness. Really disappointed by xiaomi this time.

Flashing the Evira2.3b kernel fixes this issue.

Yes! I´m facing this too, when the phone faces the sunlight the screen gets too bright with a high contrast, looks ugly, this happened to me with Samsung Galaxy S5 mini, got fixed with an update, but so far this keeps happening in the redmi note 7, any fix? other than flash a kernel?

What a simple solution, lol, already tested, I´m good to go!

So that's the setting that controls this thing? Great!
I thought that was impossible to disable. But I actually find it quite useful. I only wanted to turn it off once. I was watching something in transit and my screen would sporadically go from "vivid to normal", depending on where the sun would hit the screen/sensor.
