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?
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?
I always thought the auto levels on my phone (galaxy nexus) were too low at night or in the dark in general.
I changed mine to the following...Anyone have any tips on better levels? I find this leaves the screen brighter at night, and increments more evenly vs stock and hopefully saves some battery being its not at full brightness until its in super bright sunlight.
0=60
6=60
9=60
14=60
20=60
30=60
46=100
68=100
103=100
154=100
231=130
346=130
519=130
778=130
1168=175
1752=175
2627=210
3941=210
5912=225
8867+=225

how do you get to change these settings? any file that needs to be edited?

I have definitely had to adjust them on all my devices. On my N4(mako)* I turned them way down at low levels and way up at high levels. On my N7(flo) I had to lower them across the board.
There are so many variables: personal preference, the environment in which you use your device, the hardware of your screen, the age of your device (some screens get dimmer as they get older), and the response curve of the lux sensor in your device. Thank science we can customise it.

Hey guys
Was just wondering if setting the display mode to Basic will use less battery than if you set it to Adapt display.
Colours are more vibrant and brighter on Adapt display.
Where as colours on basic are less vibrant and less bright .
AMOLED Cinema is an optimal setting. If you select that and deselect Auto-brightness and set the brightness level to something comforting to the eyes, you may be able to achieve better battery life. Adaptive displays uses CPU power and forces the CPU to analyze GPU algorithms to tone down the display when needed, thus draining some power.

Same I use Basic.
Colors are most accurate and in fact Basic represents 99-100% of the sRGB color standard.
Other options too over saturated.
Basic reminds me of conventional LCD panels. By the way, stay away from from "AMOLED Photo," makes colors way too warm.
Am gonna stick to Basic .
I tried Adaptive display and battery was drained badly
Greetings,
the one feature MIUI has done right is brightness values. The maximum is really bright in sunlight, and minimum is dark enough to not hurt your eyes at night. This was why I moved back to MIUI from Android 9 AOSP ROMs. I wonder if it's any better on Android 10? Or are there any workarounds to at least dim the display more at night?
Im on LOS 16 and i luv the screen brightness.
Reduced screen brightness in the dark a bit...just in automatic mode move brightness slider to darker. Seems Android saves the darker values for next time !?
