[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?

Z3 Compact LED Flash

Hello! :laugh:
I was wondering, for everyone who currently owns one, is the LED flash on the back quite dim when being used as a flashlight? I had a Z1 for a while and the flashlight usage was really really low. Other flagship smartphones have huge dual flashes on the back which are really good for a powerful flashlight in the dark.
Just wondering if they've improved that aspect at all. Thanks! :good:

I can confirm that LED flash is not too strong comparing to other phones and my last iPhone 5. Maybe due to glass on the back. But I think for camera is fine.

It's not dim but it's not that bright compared to my moto g for example

plenty strong enough for me to see it, but yeah its not as strong as some. i actually like it that way, i can notice it but it doesnt light up the whole room at night...
on the z1c it was a larger led but it didnt look all that much more bright too me (it was a little more noticeable)

It's rather dim - especially if you compare it to the SGS III (my previous) and Galaxy Note III.
I often use LED in the phone as a flaslight and consider it an important feature.
You may find those two links interesting:
1. An app called Power Torch, which allows you to turn off flashlight straight from the lock screen with a long-press of the power button: https://play.google.com/store/apps/details?id=be.ppareit.powertorch
2. LED boost thread - I dind not try it yet, but certainly will try after safe root method will be available: http://forum.xda-developers.com/crossdevice-dev/sony/mod-torch-boost-led-power-using-z1-t2886705

Anyone else having auto brightness issue?

Sometimes brightness gets too low.... even in lighting conditions and i have to adjust it manually. I think there is some callibration problem

I am also facing the same issue. But I have accepted this considering the low cost of the device

Its not about the price because earlier i had moto g turbo...a bit lower price than this but there was no such problem. And with g5 plus its not like there is brightness problem...in normal lighting...it gets too bright also sometimes...hope it can be fixed in os updates or in custom roms.

Turn off your adaptive, set brightness to Max. Turn on adaptive. It will adjust accordingly now

I actually may have jumped the gun. Still doesn't adjust very well on its own.

Yep facing same issue

So I've messed around with this a lot and I keep adaptive on with my brightness set around mid point. It seems to adjust pretty well for me.

Yes, same here

Tried the mentioned steps of disabling adaptive and re-enabling after maxing out display and found it to be better now

i actually like the lower brightness

Same as some others here, brightness is too low in dark places.

Remember that adaptive brightness also changes as to what your brightness slider is at. Personally, I used to have this issue while having my brightness at 1/2. Now I have it at 3/4 and my issues seem to have gone away.

Yeah, I find the auto brightness pretty useless. It's too dark in some indoor lighting situations yet too bright in an almost-dark room. I find it easier to just adjust it when I need to. I wish it worked well, but I don't like the way it adjusts the brightness. It might be fine for some people, but it's not for me.

Turn off auto-brightness. Pull down notification shade/shortcuts. Adjust brightness according to your liking.
Then again, I never liked auto anything. I like to be in control.

Seems it worked. There is a sensor that manage the this process? Thank you for your reply.

Camera flash brightness with default camera app

Hi,
I was very disappointed with camera flash intensity one day while my colleagues were taking portraits in low light with their high intensity flash on xiaomi mobiles but my Oneplus Flash couldn't do anything.
I thought it was the hardware design and i thought to live with it.
But yesterday i installed magnifier app from playstore and observed that the flash was brighter compared to camera app.
My question is, is there a way to increase the intensity by increasing the amount of current pumped to the LED?

You may be able to do it with a custom kernel. Though they generally only offer options for the notification LED, not the flash.

[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.

For me disabling the auto contrast doesn't fix the issue. The screen still goes crazy on sunlight. Any other suggestions except flashing a kernel?
