How to Fix a Red Dot on an iPhone
IPhones have LCD screens made up of tiny little squares, or pixels, that change colors to display images. Sometimes, however, these pixels become "stuck" and remain a single color -- red, green or blue -- regardless of what color the image is. If you see a red dot on your iPhone's screen, this means a pixel is stuck. Gently rubbing the screen where the pixel is will make it work again.
Things You'll Need
- Damp cloth
- Pencil with unused eraser
Turn the iPhone off. Take note of where the red dot is on the screen.
Put a damp cloth over the screen.
Rub the edge of an unused pencil's eraser on the iPhone where the red dot is located, over the cloth. Continue to rub for 30 seconds.
Turn the iPhone back on. Keep rubbing until the phone is fully illuminated.
Stop rubbing and take the cloth off. The red dot will be gone.
