Dead pixels on the Samsung Galaxy S25 Ultra can be frustrating, appearing as small black, white, or colored dots that don’t change. These can be caused by hardware defects, stuck pixels, or software glitches. Here are several methods to try and resolve the issue.
1. Restart Your Phone
A simple restart can sometimes fix dead or stuck pixels if they are caused by temporary software glitches.
- Press and hold the Power button.
- Tap Restart and wait for the phone to reboot.
- Check if the dead pixels are still visible.
2. Use a Pixel Fixing App
Pixel fixing apps can help by rapidly flashing colors to revive stuck pixels.
- Download a dead pixel fixer app from the Google Play Store.
- Open the app and run the pixel refresh tool.
- Let the process run for 10–15 minutes.
- Restart your phone and check if the pixels are working.
3. Apply Gentle Pressure to the Affected Area
Sometimes, gentle pressure can help reactivate stuck pixels.
- Turn off the phone.
- Use a soft microfiber cloth to apply gentle pressure to the affected area.
- Power the phone back on and check if the dead pixels are gone.
- Be careful not to press too hard, as excessive force can damage the screen.
4. Use a Screen Burn-in Fixer
If the dead pixels are caused by prolonged static images, a burn-in fixer can help.
- Install a screen burn-in repair app from the Play Store.
- Follow the app instructions to run a color-shifting animation.
- Let it run for at least 30 minutes.
- Check if the pixel issue is resolved.
5. Check for Software Updates
Software updates often contain fixes for display-related issues.

- Observe if the dead pixels improve.
7. Try a White Screen Test
A bright white screen can sometimes stimulate stuck pixels back to life.
- Open a blank white image on your phone.
- Set the image to full screen and leave it on for 10–15 minutes.
- Check if the pixel starts functioning properly.
8. Enable Dark Mode
Switching between dark and light modes can sometimes help shift pixels.
- Go to Settings > Display.
- Toggle Dark Mode on and off.

9. Reset Display Settings
Resetting display settings can restore proper pixel function.
