What You Should Know about that Black Dot on Your Phone

Nowadays, having a smartphone is necessary, but with it comes the inevitable wear and tear from everyday use. One of the most common issues is a black spot on the screen. 

If you have noticed this issue on your device, you may be wondering what caused it and what you can do to fix it. Fortunately, screen repair experts have the answers! Read on as they detail the cause and solutions for the appearance of a black spot on your phone screen. 

What Is that Black Dot? 

Do you have a black spot on your phone screen? You are not alone! This issue is surprisingly common and can be caused by several different things. Fortunately, there are ways to repair it and potentially save your phone from further damage. 

Phone screens are incredibly durable and can withstand much wear and tear. Unfortunately, even the best-made phones can suffer from black dots.

You see this black dot due to the pixels on your phone screen that do not light up. The pixels are the tiny dots on the screen that display different colors. You can see a black dot on the screen when these pixels do not light up.

According to screen repair technicians, this black dot is usually harmless and will not affect your phone’s performance. However, the large or growing black dot could indicate a problem with your phone’s display.

Why Does This Happen?

This annoying black spot might result from a manufacturing defect known as a dead or stuck pixel. Dead pixels are caused by a transistor that has stopped functioning correctly. On the other hand, stuck pixels are caused by a transistor stuck in an on or off state. Both types of defects can be fixed, but it is essential to understand the difference between them and how to repair them.

Dead pixels are caused when a transistor fails to turn off completely. It causes the pixel to appear black or a color that is not the same as the rest of the display. You can identify a dead pixel by looking for a black or colored dot on an otherwise uniform background. 

Dead pixels can usually be repaired by software or hardware solutions. Software solutions work by repeatedly turning the pixel off and on to revive it. If this does not work, hardware solutions such as replacing the damaged transistors can be used.

On the other hand, stuck pixels are caused when a transistor fails to turn on completely. It causes the pixel to appear white or color different from the rest of the display. Stuck pixels can be identified by looking for a white or colored dot on an otherwise uniform background. 

Can This Spread?

No, dead pixels do not spread. It is a common misconception and one that many people have about dead pixels on computer and phone screens. 

It is essential to note that dead pixels are not contagious and does not spread from one pixel to another. Therefore, they are a static issue and cannot “infect” other pixels. While more than one dead pixel can exist on a screen, it will not spread to other areas.
