When we buy a mobile phone, most of them can present factory problems that if we detect them in time we can demand that we change it or be repaired using the guarantee. Some of these problems have to do with your LCD screen and then we are going to tell you what you should do to fix the dead pixels on my phone screen.
Before continuing we will explain to you that it is a dead pixel, on an LCD screen it is made up of hundreds of pixels and each of them by three sub pixels. The pixels are responsible for providing the color and image that we see on the screens.

This pixel that does not light up or does not produce color, is known as a dead pixel, there is another term that is good for you to know and that is the stuck pixel. This is nothing more than the non-functioning of one or two sub pixels . And therefore it does not produce the color that it should and that is when we see colors that do not correspond to the rest of the image.
