Your iPhone screen is comprised of hundreds of thousands of tiny pixels that render an image. Each pixel is made of three colored subpixels; red, green and blue. Normally these subpixels electronically cycle through the three colors depending on the displayed image, but if one get stuck in the “on” position, a solid-colored dot appears on your screen. Gentle pressure on the stuck pixel may fix it, but results are not guaranteed.

Step 1

Make note of where the stuck pixel is on your iPhone screen. Use a dry erase marker or low-tack painter's tape to mark exactly where the stuck spot is. Repairing a stuck pixel requires precision.

Step 2

Power down the phone. Place painter's tape over all openings, such as the headphone jack and USB connector.

Step 3

Wrap a blunt-tipped object, such as a permanent marker cap, pen stylus or the edge of a pencil eraser, in a damp, soft cloth. Avoid fabrics that may scratch your screen. Don't dampen the cloth so much you risk water damage to your iPhone.

Step 4

Apply pressure on the stuck pixel with the wrapped object. Apply gentle pressure on only the stuck pixel for 10 seconds.

Step 5

Wipe up any remaining moisture on the iPhone's screen and power on the iPhone. Check for the stuck pixel. Repeat the procedure if the pixel is still stuck.


  • Try this pixel-saving technique at your own risk. If you cause more damage in your repair efforts, you may end up with more than just a single red pixel on your screen. Your warranty may not cover stuck or dead pixels, and you may either have to live with the screen problem or pay for repairs.


  • Work slowly, carefully and deliberately. Pressing too hard in too wide of an area can cause more damage to the stuck pixel or surrounding pixels.

  • If your iPhone is jailbroken, you can download and run the ScreenTest app available from Cydia. This program focuses on the stuck pixel and performs a color-changing cycle in an attempt to “unstick” it.
