How to FIX S8 S9 S10 Note 8 9 10 RED SCREEN ISSUE DEFECT Samsung GALAXY burn in OLED

Work around to fix the screen for the time being. Screen burn-in, not to be confused with the similar — though completely temporary — image retention (or image persistence), is a permanent display artifact created when static images remain on the display for extended periods of time. When this occurs, an outline of the image can remain “burnt” into the screen even after it has been turned off, or replaced with a different picture. It’s an issue which can be found in almost all displays, though modern technologies have gone some way to reducing it.
As for how long it takes for this to occur, it’s difficult to provide a precise time because it depends on many factors, such as screen brightness, the type of hardware, and the type of image.
To start off, you'll need to undo the burn-in on your phone. It's a fairly simple process which only requires the installation of an app that'll invert your screen, which forces the pixels to unstick from their current burned-in color(s). The app we'll be using is called AMOLED Burn-in Fixer, and will work on all devices with an AMOLED screen. After you've fixed the burnt-in pixels, you'll want to make sure the problem doesn't happen again. The easiest way to do this would be to enable always-on Immersive Mode, which will autohide your navigation and status bars to keep them from getting etched into the screen, while still giving you access to these functions by simply swiping in from the edge of your screen.
The process is fairly simple, but it does require a computer with ADB installed. We recommend hiding both the navigation and status bars since those two areas have proven to be problematic. So to ensure that the screen burn-in doesn't come back, check out the complete guide at the link below for the ADB commands to hide those bars.
