Why is my screen dark

hello Muhammad

If you have a black spot on your iPhone 8 Plus screen and pressing on it makes it worse, it is likely a physical issue with the display. This could be caused by a number of factors, including:

1. Dead pixels: A dead pixel is a pixel on the screen that is no longer functioning properly. This can cause a black spot or other visual abnormalities on the screen.
2. Physical damage: If your iPhone has been dropped or otherwise physically damaged, it could have caused damage to the screen that is causing the black spot.
3. Moisture damage: Exposure to moisture or liquid can cause damage to the display and result in black spots or other issues.
4. Electrical malfunction: In rare cases, an electrical malfunction could be causing the black spot on the screen.

Unfortunately, if the black spot on your iPhone 8 Plus screen is caused by a physical issue, it will likely require a screen replacement. You can contact Apple support or an authorized repair center to schedule a repair.
