First things first, you need to know that a screen-burn-in is a hardware problem. Attempting to fix it using software is almost always an exercise in futility. It is no surprise, therefore, that the reviews of most of these apps are mixed. But then what exactly do these apps do? And what about users who claim that their issue was fixed after they installed and used the app?

While some of these apps can be of help, and there are reviews where people have claimed they work, the general philosophy of these apps is to try and “burn” the rest of the screen to match the colors of the area. While this might work for you initially, you should know that eventually, you aren”t helping solve the issue. Think of these apps as temporary workarounds until you replace your display.
