•What is Screen Burn-in?
Ghost image or screen/image burn-in are names given to a permanent discoloration of your smartphone’s screen caused by irregular pixel usage. The prolonged use of static images can create a permanent shadow or ghost of that image on the screen. This problem is more common than you think, and happens most often on AMOLED screens.
•How did it happen?
The screen ghost happens when phosphorus compounds that emit light to produce images lose their intensity with prolonged use. Moreover, the irregular use can "burn" an image onto the screen which will be visible all the time.
•How to FIX?
Many apps which are available in the Play Store promise to reduce or even stop the problem. One is the Screen Burn-in Tool.
The concept is simple: a sequence of primary colors is displayed on your device, restoring the "burnt" pixels. In fact, this was the original function of computer screen-savers: one dynamic image that appears when the screen is idle to makes the pixels "exercise" and ensure that the same area of display doesn’t remain constantly illuminated.

Would I be correct in the assumption that if you have a program in which you can change the program's appearance, would it consume more battery power if the appearance has more "lit" pixels than "dark" or "unlit" pixels?
For example, I use a calendar program called ThumbCal. It comes with numerous skins. For the purpose of this discussion, let's assume that there are only two skins. One skin is basically a white background with black lettering, while the other is a black background with white lettering.
Clearly, the one with a white background is considerably brighter than the one with a black background. Both are equally legible, but the white background is brighter because more pixels are lit to display the white background.
My question is this, will the program use MORE battery power if the white background skin is used? It seems logical because more pixels are lit, or on.
Am I right?
Thanks,
Peter
No. On an LCD screen, like the HD2 has, there is a uniform backlight under the screen, white pixels let that light through, while black ones block it. Even on a full black image, the same amount of light is still generated, only to be blocked and dissipated in the screen just afterwards. So, consumption is independent of the displayed image.
It would be true on an OLED display, where each pixel is indeed an independent light source.

Great explanation, and completely understood. Thank you.

Hi
Just wondered if the Screen Adjuster app poses any risk of damaging the S4 screen after a while? My phone has a noticeable yellowy green tint which makes photos and videos appear slightly green. I downloaded the Screen Adjuster app which lets you adjust the red green and blue sliders and it reduces the yellow tint (although it doesn't work when playing videos annoyingly).
I have seen on other similar apps the developer putting a warning not to use the colour slider tints on OLED screens as it damages them, so I just wondered if I always have the Screen Adjuster switched on whether I am damaging my screen in the long run?
Hi 2 All,
I have galaxy s4 installed offical 4.4.2, when i open setting or task manager in very dark place, i saw abnormal brightness in background.
i thinks it should be black as it is amoled.
is it normal or serious?
is it sign of screen burn?

Open a completely black image. Download a solid black JPG from google as your test. Do the same thing with a completely white image.
Look at those images in full screen mode.
If there is burn in (which CAN happen on an LED screen, though it's actually pixel fading rather than burn in) you should be able to notice it with this test.
If you see fading in the white image, or general non-uniformity in the brightness, it's a sign of fading. (burn in)
If you see a ghost image in the black image, then something is wrong. It means the screen is lighting up when it shouldn't be.
You should not be able to see a residual image on a black screen like you used to with an old CRT computer monitor. The burn is doesn't work that way. What happens is the pixels lose some of their brightness over time. It's subtle, and if the screen is fading uniformly you probably won't notice. But when 1 spot isn't fading, you notice it quickly. This is most commonly seen with the status bar. If it's always black and the area right beneath it is always colored, then the black status bar wont' fade and the rest of the screen will.

Thanks Sir,
actually it was lcd problem
Hello guys,
To save battery thru screen use as much white background as possible cuz LCD Screen uses White pixel backlight and white will use less battery,, it's the complete opposite of amoled screen while they use black pixel.
To save battery more turn on gps but device only, cuz the Google play services (locations)
Use the wifi and network to share the location, so leave it at device only and the GPS will be offline until you use an app needs GPS
More tips I will share,
Thanks
this with lcd screen is bull****. only way to save battery on display is to set brightness down.
backlight for the whole screen makes the light, not the pixels itself like on amoled.
He actually is true but the effect is so low it doesn't matter.
To Display a black (or dark) image the LCD needs to block the backlight (which is always on) and this in fact requires more energy than letting the light pass and displaying a white screen.
Hello. Recently I've been experiencing problems with the AMOLED display of my Samsung Galaxy S4 i9500, best known as "Burn in" (The display some parts walk marked in a darker color on the display, with the notification bar and browser )
I found this app:
https://play.google.com/store/apps/details?id=com.feetstech.screenburn
It has several settings to run the program (they say that it is recommended to use in Brightest level to best execution)
If one of these App helps reduce the Burn IN, what is the recommended setting in the app?
Thank you.
Screen burns are a result of long-term image displaying.
Leaving the screen on with a static image displaying at a high brightness accelerates the process.
This is hardware degradation through usage. It is very unlikely an app can fix it. The very least it can do is hide it. But it will not magically repair the screen.
