How To Fix Black Spots on Phone Screen

A pristine phone screen is essential for an optimal viewing experience. However, many users face the frustrating issue of black spots spreading on their phone screens. These spots on the screen can be due to dead pixels, stuck pixels, or screen burn-in. This comprehensive guide will walk you through the causes of black spots on cell phones and provide effective solutions to fix them.

Causes Of Black Spots on Phone Screens

Before going into the fixes, it’s crucial to understand what causes black spots on phone screens:

  • Dead Pixels: Dead pixels are pixels that have stopped working entirely and appear as black spots. These pixels do not respond to any input and remain black regardless of what is displayed on the screen.
  1. Stuck Pixels: Stuck pixels, on the other hand, are pixels that are stuck on a particular color. These might appear as black spots if the pixel is stuck off, or they can be red, green, or blue if stuck on those colors.
  2. Screen Burn-In: Screen burn-in happens when static images are left on the screen for extended periods, causing a permanent ghost-like image to appear. This is common with OLED and AMOLED screens.
  3. Physical Damage: Physical damage from drops or impacts can also cause black spots to appear on your phone screen. These spots are usually more irregular in shape compared to dead or stuck pixels.

Identifying the Issue

The first step in fixing black spots is identifying the cause. Here’s how you can do it:

  1. Dead Pixels Test: Use a dead pixel test app like “Dead Pixel Test and Fix” for Android or visit the JScreenFix website on your iOS device.
  2. Stuck Pixels: If the pixel changes color or responds to pressure, it’s likely stuck rather than dead.
  3. Burn-In Test: Display a solid white or solid color image to check for burn-in. Burn-in usually appears as faint, ghostly images of static elements like navigation bars.

Step 1: Use Pixel Fixing Software

Several apps and tools can help fix stuck or dead pixels:

For Android Users

Dead Pixel Test and Fix

  1. Download the app from the Google Play Store.

For iOS Users


  1. Go to the JScreenFix website using your mobile browser.
  2. Tap the “Launch JScreenFix” button.
  3. Drag the pixel-fixing window to the area with the black spot.
  4. Leave it running for about 10 minutes.

These tools work by rapidly cycling colors to stimulate the stuck pixels and bring them back to life.

Step 2: Apply Gentle Pressure

Applying gentle pressure to the affected area can sometimes help fix stuck pixels:

  1. Turn off your phone.
  2. Wrap a soft cloth around your finger or use a stylus.
  3. Gently press on the black spot and the surrounding area.
  4. While applying pressure, turn on your phone.
  5. Remove the pressure and see if the black spot is gone.

This method works by redistributing the liquid inside the LCD to stimulate the stuck pixels.

Step 3: Use a Screen Cleaner

Dirt and debris can sometimes cause black spots to appear on your phone screen. Cleaning your screen can help:

  1. Turn off your phone.
  2. Use a microfiber cloth and a screen cleaner.

Step 4: Screen Replacement

If the black spots persist and are due to physical damage or cannot be fixed using the above methods, you might need to consider a screen replacement. Here are your options:

  1. Contact Manufacturer Support: Check if your phone is still under warranty and contact the manufacturer for a repair.
  2. Visit a Professional Repair Shop: Take your phone to a certified repair shop or an authorized service center.
  3. DIY Replacement: If you’re comfortable with DIY repairs and your warranty is void, you can purchase a replacement screen and follow online tutorials to replace the screen yourself. Note that this can be risky and may void any remaining warranty.

Step 5: Preventing Future Issues

Prevention is always better than cure. Here are some tips to prevent black spots from appearing on your phone screen:

  1. Use a Screen Protector: A screen protector can help protect your screen from physical damage.
  2. Avoid Static Images: Avoid leaving static images on the screen for long periods to prevent burn-in. Use dynamic wallpapers and enable screen savers.
  3. Handle with Care: Be cautious with your phone to prevent drops and impacts. Use a sturdy phone case for added protection.
