I think this issue is present on most android platforms and devices however it's particularly bad on my Fire Stick right now. Subject says it all, why must app developers use white instead of black for this pre-app load process? Is anyone aware of any system-wide tricks that can be used to override these white loading screens and use black instead?

Greetings,
I just purchased my Samsung Galaxy Nexus but I noticed after some months of use, some strange blue lines that appears only on blue, grey or specially light colors as white backgrounds. I am very upset since I bought this good cellphone but noticed the screen issue. People told me that those blue lines where just a software problem but the thing is that I recently upgraded from 4.2 JellyBean to 4.4 KitKat and those annoying lines still appear on specific backgrounds. I forgot to mention that those blue lines appear in full-screen mode where the notification and the digital buttons bar are when they hide while in that mode, for example: when playing games, visualizing text or images, watching videos on Youtube (all of it in full-screen mode). You got the idea, right? Its like when the full-screen mode is on and the functional bars of the Nexus fade, it is supposed to be the same color as the whole background, but not; it appears like a tone of blue instead. This has nothing to do with the camera by the way.
I now think that the issue is related to some problem with the screen and hardware. I don't really want to replace the whole screen with a new one since Nexus screens are very expensive. I can't claim a warranty as well.
So, the questions are:
¿Does anybody have or have had the exact or similar issue as me?
¿Can someone please explain me what's going on and give me a solution?
I will leave few images bellow where the blue line is more visible:
1st Picture: When Youtube is loading the video, the notification and digital-button bar are gonna fade to play the video in full-screen mode.
2nd Picture: While the video is playing in full-screen mode, on the edge of the screen where previously was the notification bar, the blue line appeared, you can see it easily.
3rd picture: While reading any type of text or viewing a picture in full-screen mode where the notification and digital-buttons bar fade, the blue line appears again and its very easy to see it.
4th Image: This case is different, on a background with dark blue and black colors, there is some blue tint effect that is slightly notorious, the picture taken from the camera doesn't show it very well.

Yeah dude, it really sucks and its kinda annoying when watching videos or reading something. Google should make something about it on future cellphones!
If you fix it or at least reduce the blue shadow a little please notice me, I am very upset about it. :crying:
My „blue lines” appeared after I dropped the phone
Seems like standard Galaxy Nexus AMOLED burn-in. Try something like this but dont expect too much.
Screen burn in. I have it too. There's no fixing it on an AMOLED display without replacing the screen. This is my first and last device I will buy with AMOLED.
I'm looking into purchasing the Galaxy Tab S 8.4, but one of my big uses is for reading on the Kindle app. Currently, on my LCD device I read with a black background and white text to reduce the light emitted as I do a lot of reading before bed, but it still is a lot of light which can keep my wife awake. Does the Galaxy Tab S actually turn off the pixels producing black, or is just very, very dark? I know AMOLED is supposed to turn them off, but I've heard conflicting reports that some devices do and some don't. Would someone be able to load up the Kindle app and set it to black with white text and let me know if it actually shuts off the pixels so it wouldn't be as bright in a dark room?
Thanks!
The Kindle app set to black background truly gives a black background, if set to use system brightness you can also get a very dim white for the text. If looking at something like the dark theme in Tapatalk you don't get black, the background is a dark grey. A bonus of running the kindle app like this is that battery life should be extended, compared to using a white background.

I could say that this is true black. Comoared to my old 7.7 which gives a slight glow when displaying pure black. This one seems like the screen is off

Same here. What he said. Your wife will be happy.
Hey XDA, wanted to get thoughts or suggestions on this.
I noticed what appears to be a stuck pixel on my m8 today, but it doesn't seem to make a lot of sense to me.
Pixel appears to be stuck on (all white), but is only visible on lighter images such as white backgrounds and other lighter colors. Not visible on gray or black images, which seems counter intuitive.
I've restarted several times, run a pixel fix app for about twenty minutes, and verified it's also visible in TWRP recovery, so definitely appears to be hardware.
Any thoughts on a fix, or why it's only visible on lighter backgrounds although is "stuck on" and all white itself? I'd figure it would be more readily visible on dark scenes, but nope!
Thanks in advance for any input.

Im not quite sure how the display works, but maybe the darker images dont activate or light up that actual pixel? Anyways, why dont you bring it to your dealer?
I use my Android tablets for reading, using Google Play Books. I prefer a bright white background. With my Nexus 7 (2013) it's a pure white background, just the way I like it. With the Tab S 8.4 I can't seem to achieve bright white. It's more like a light sepia. I know sepia is a choice but that's a very dark (to my eyes) background. I've also played around with the Screen Mode but none of the choices seem to change the GPB background at all. I've turned Reading Mode on and off but I don't see any difference.
I know there are other reading apps but I like having a large library stored in the Google cloud and the ability to switch devices and have the bookmark change with it.
Any suggestions on how to change the background color for just Google Play Books?
I'm having the same problem with my Galaxy Tab 4 7.0". I've tried everything you have and it also doesn't work. I've also noticed that when I click the home button on my device it turns bright white just before closing so I know that the app and device are capable of displaying the correct color.
I know this isn't an answer to your question, just letting you know that you're not the only one. In fact your post is the first I've seen about this issue and I've been Google searching different variations of the question.
Those are my settings, and whites are white as should be.

I seem to get better whites with Basic rather than Cinema. When I use Cinema white has a strong blueish tint, especially on video. Whites on Basic are fine while watching movies, YouTube, etc. Google Play Books is now better with Basic and Reading Mode off but it's still not as bright a white as I would like.
For example, I was watching Ex Machina. An early scene has a helicopter flying over a glacier. With Cinema it looked like a sea of blue. I changed to Basic and the snow and ice turned white. You lose the oversaturated colors with Basic but the blueish whites really bother me on the other settings.
Call me odd but i don't want a background on my homescreen or lock screen. I simply want it plain black. But I see no option to simply pick no background which with every other smartphone I ever owned or messed around with resulted in a plain black background. How do I set no background? Thanks

Just find a black image and use that.

go on google find a black background and set it as the wallpaper?
Take a picture on your phone in a dark room with your camera facing down on a desk and set it as the wallpaper?
I had thought of doing that. But I thought the idea of the no background was so that the background wasn't consuming resources. Every time I exit an app it has to load the background like android decided to turn it off while in the app. So even though the background image would be all black it's still going to have to go through that processing. I am not sure of the impact of that. I know with older devices having no background was recommended because it consumed resources. I don't know why there is a no background setting, it seems kind of stupid that it was left out.
