How to Avoid Pressure Spots on iPhone 11 Screen?

iPhone 11

One of the deadliest and most frustrating issues you could have with your mobile phone is screen damages. And for pressure spots on LCD screens, it’s somewhat annoying than breaking the whole screen itself, as it requires going for replacement in most cases.


What is a pressure spot? What types of pressure spots are there?
As its name implies, pressure spots on phone screens can render the display useless (or irritating, based on how you see it) by creating spots of different shapes and styles on the screen. These spots show continually, and most times, permanently on the display and can obstruct your viewing or cause other problems such as dead pixels, flickering, or blurriness.

When you apply too much pressure on your phone’s display – whether accidentally, intentionally, or carelessly, it damaged the LCD components, hence creating different spots on the display.

Pressure spots on LCD screens can come in different forms and shapes depending on the density of pressure applied. Sometimes, the spots can be whitish, deep black, or come in various colors depending on what’s currently showing on the screen.
