[REQ]Tint of display?

Is it possible to change somehow the tint of luminescence display? Make it more warm or cold. Display in my SGS has a very cold shade, a lot of blue. I would like to add a little red to align white.

It's a characteristic of AMOLED screen. As you use it longer, the blue tint will start reducing.

Though that doesn't change the fact that the possibility to change or affect white point and/or gamma of the display would sometimes come quite handy. The color temperature of Galaxy's display is indeed quite high, yet it is so good picture-wise that this becomes an issue (ie. when viewing photos).

Just open any movie with the stock video player. Go to Settings and then Colour Tone. It will affect the whole system.you have 3 options warmer, normal and colder. Hope this will help

That's a great tip, thanks! Even though it's most likely just a bug
So you obviously can alter the display's color temperature system wide somehow. I wonder if this could be made into an app with customizable warmth settings... Too bad I'm not a programmer...

And speaking of the devil...

Menu - settings - 3º option
It appears blank on my phone, but leads you to temperature settings
The screen has a blue reflection when off. I also tested it playing the same video on the phone and on my laptop (300 nits LED screen) and the video on the phone was defintely more green-blue.
This is more noticeable on low brightness setting, try it on Kindle app, test settings, you have a slider for brightness. You'll see how low brightness leads to a blue-green tint, not neutral gray.

if some one could could develop an app for the sgs that does this i would pay.

settings menu is only available if you start the videoplayer app and select a video to play within.
if you start a video from the gallery, there is no option

Is the galaxy s i9000 different in this respect from the samsung vibrant. My vibrant does allow me to adjust color tone in the video player, but IT DOES NOT change the color tone of the WHOLE SYSTEM. Once I exit out of the player, everything is back to blue. Also the warm tone in the video player looks fake, just applies red on top of the blue, looks weird.

Do you guys find this annoying? - Browser Brightness Setting

I want the Browswer to either,
1 - utilize the auto brightness function
2 - keep the brightness the same as what my setting is on
Is this that hard to do? why does the browser get it's own friggin brightness setting? At lease give us an option to take route 1 or route 2 on top of being able to change it.
Definitely something to think about in future roms.

And here is another example of why I despise auto brightness settings on screens. I like mine cranked all the way...except on my Sharp Aquos because that would lead to retinal bleeding at over 450nits

Just swipe from left to right along the notification bar to change the brightness to what you want.

i'd much prefer it automatically matching the brightness to the system setting. Hopefully, that will be fixed in the upcoming roms.

BTW, to increase screen brightness, turn Power Savings off in the Display settings. Doing this keeps the screen at 100% all the time --the browser and other apps will not dim the display anymore.

Very annoying. I have no idea why someone would do this. It makes no sense.

Same here, i don't need a very bright screen to browse
But having a auto for browser is basic setting in my mind though

But then you go outside and you can't see your screen because it's so low. This is specifically the reason it bugs me. I too love low brightness indoors but it sucks when you can't see the screen very well to turn it back up.

My only complaint is every page has to be white like a bright sheet of paper.
Back in the old days, computers had white text on black screens. Worked great at night or in dark rooms.

Screen colour problem, please help

I was looking at Google Map when I noticed the colours changing. It was as if the contrast was suddenly being reduced making the colours look washed out. When I went to my Home screen my windmill live wallpaper is also looking washed out because the grass no longer looks very green. Has anyone else experienced this problem?
I attach some screen captured to show what it looks like.

Go to settings>display>screen mode you have changed the color management. And see if you have enabled auto adjust screen power. Maybe on of those are responsible.

Do you use Custom Power saving?
Could be your battery running out, so its reducing your display to save power.

I'm not using power management and I have the phone on charge.

I've discovered why there's a difference in my Google Maps screens. It seems that sometimes the map is overlaid with a white circle which makes it look washed out. I attach a screen shot so you can see what it looks like. I think the circle is highlighting an area around my satnv location.
But I'm still not happy with my windmill which still looks washed out.

The colours on my windmill home screen have mysteriously returned to normal

wow man there is a huge difference.... no way my gnote is not doing this for sure... try to upgrade to 2.3.6 and see if that fixes it

you're sure it's not a 'feature' of the windmill LIVE wallpaper?
On the second image you have good weather, the sun is shining. On the first image however, it seems as if you have bad weather, no sun, only clouds, thus the gray layer.
So maybe it's nothing the Note is responsible for, but the weather dependend Live Wallpaper.

I know is not the same problem but maybe related,my device have some brightness change in the display,many times i'm reading and see the screen do some dimming the screen lower down the brightness and go back after like 30 seconds to the normal bright,I have enable the Auto screen power but i try desable and the result are the same.

I think you are probably right for nothing has changed except the weather.

any current roms have this feature?

hi all, looking for a rom for my N7 that can change the display to only display red for when i use sky safari on it while out stargazing. (red helps protect night vision) on my nexus one with CM7 it has render effects settings screen where you can change the color of the whole os to basic colors etc. any roms out for the N7 that can do this globally as well? and before you say it yes sky safari has this feature inside, problem is unlock screen does not as well as say accidentally hitting home etc. one bright flash of white light and you loose dark adaptation for 5-10 even 20 min so its kind of important and most people go the easy simple route of putting red cellophane on their screens, but if i can get around that and i know its possible to i would like to.

google skymap has a night view mode built in.

apparently sky safari has a night view mode built in also, look for it in the settings.

yeah sky safari has it, and it also has a setting to keep the device from sleeping because the problem is the lock screen and any other screen you might accidentally pull up will not be a dim red light and will instantly damage night vision if pulled up. anyways i rooted my N7 and took at look at a few roms and so far have not found one with this feature. looks like it was put into CM7 for the potential power savings due to the screen on the nexus one as well as many other phones being AMOLED. on tablets with LCD's theres no savings to be had so nobody's implemented it into a JB rom so far.

Tasker might do what you need. You make a profile to do things like dim screen brightness, change wallpapers, dim/kill LED notifications, etc. Set it to trigger when you open your Skymap app & your light sensor senses that it is dark (I don't know what that setting looks like).

This app has astronomers moder for the red tint.

Blurry effect when scrolling on dark screens

Hello guys,
I was hoping to know if you also have this effect on your oneplus 5's.
The best way to describe is when you are on dark screens like twitter's night mode and you have some images with dark margins.
When you scroll up or down, does it appear a trail that disappears after some miliseconds? Like the screen refreshing itself making that trail disappear.
If you wanna try do this: twitter, night mode, follow for instance Nvidia (his logo is black and dark). Then go to home screen of twitter and try to find a nvidia's twitt. When you find it, look to his logo and go up and down. Do you notice something on the image itself? Like a trail of black pixels or blur effect that disappear after a while?
Hope that you can understand me.
Edit: don't know if I can post links here, if not please tell me that I remove it. This link is from Reddit where it appears an image where you can try this effect:
https://www.reddit.com/r/GalaxyS6/comments/34t923/is_your_screen_defective_test_for_yourself_by/
Edit 2: it appears that the effect is more visible on low screen brightness
Best regards.

Yes, I have noticed it as well though I also had it on my OP3. I think it is more of a thing with OLED screens and low brightness.

Yes, I agree. As this happened on my note 4 as well as my axon 7, oneplus 3 and oneplus 5

Yep, I've experienced that once. Dark purple logo on black screen

It happens on Amoled screens when the backlight is low. I have seen the same thing on all my Samsung phones as well.

I also confirm, low brithness OLED screen (samsung s3, s4, s5, s7, op3, op5)
oled are good for low battery consumption and high contrast ratio (blacks).
Otherwise, lcd pannels will be faster and more accurate with colors.
