Spots on Mobile Screen: Causes, Fixes, and Prevention Guide

Understanding Spots on Mobile Screen

A mobile screen is one of the most important parts of your device. It not only displays content but also functions as a touch interface. When you see unusual spots, it usually indicates either a hardware or software issue. While some spots are minor and harmless, others may require immediate attention.

Types of Spots on Mobile Screen

• White Spots: Bright dots that may appear due to pressure damage or uneven backlighting.
• Black Spots: Usually dead pixels or liquid damage, appearing as dark patches that do not change color.
• Colored Spots: Green, purple, or red spots often caused by stuck pixels or screen burn-in.
• Spreading Spots: Marks that grow larger over time, often linked to liquid damage or internal cracks.

Causes of Spots on Mobile Screen

There are several reasons why you might notice spots on mobile screen. Let’s look at the most common causes:

1. Physical Damage

Drops, bumps, or applying too much pressure can damage the delicate LCD or OLED layers. Even if the glass doesn’t break, internal damage may cause black or white spots to appear.

2. Dead or Stuck Pixels

A dead pixel remains black and does not light up, while a stuck pixel stays locked in one color. Both issues create visible spots that are hard to ignore.

3. Liquid or Moisture Damage

Accidental spills or humidity can seep into the screen and create dark or discolored patches. In severe cases, the damage spreads and ruins the display permanently.

4. Overheating

Excessive heat can damage screen layers, especially in OLED displays. This may lead to yellow spots or screen burn-in over time.

5. Manufacturing Defects

Sometimes, new phones develop screen spots due to poor quality control or defects. If this happens under warranty, you should request a free replacement.

How to Identify the Type of Spot

Not all spots are the same. To figure out what you’re dealing with, try these methods:

• Use a pixel test app to check for dead or stuck pixels.
• Observe whether the spot changes size or color over time.
• Check if the screen has external cracks or signs of liquid damage.

DIY Fixes for Spots on Mobile Screen

Some screen spots can be fixed at home without professional help. Here are a few safe methods:

1. Pixel Revive Apps

Download apps that rapidly change colors to stimulate stuck pixels. This sometimes revives them and eliminates small colored spots.

2. Gentle Pressure Method

Apply light pressure using a soft cloth on the affected area. This can sometimes realign pixels, but it should be done carefully to avoid further damage.

3. Software Updates and Resets

In rare cases, software glitches cause display issues. Updating your phone or performing a factory reset may solve the problem.

4. Proper Cleaning

Dust or dirt trapped under screen protectors can appear as spots. Remove the protector, clean the surface with a microfiber cloth, and reapply if needed.

When to Seek Professional Repair

DIY fixes are only effective for minor issues. You should seek professional help if:

• The spot keeps getting bigger.
• The touchscreen becomes unresponsive.
• There are visible cracks or liquid inside the screen.
• The cost of fixing is cheaper than replacing the device.

Prevention Tips for Spots on Mobile Screen

Prevention is always better than repair. Here’s how you can protect your phone screen from developing spots:

• Use a high-quality screen protector to prevent scratches and minor pressure damage.
• Avoid exposing your phone to excessive heat or moisture.
• Handle your phone carefully and use a protective case.
• Clean your screen regularly with a soft microfiber cloth.

Cost of Fixing Spots on Mobile Screen

The repair cost depends on the type and severity of the issue:

• Minor fixes: Dead pixel repair or software reset may cost little to nothing.
• Screen replacement: Typically ranges between $50–$300 depending on the brand and model.
• Warranty claims: If your phone is under warranty, you may get a free repair or replacement.
• Insurance coverage: If you have device insurance, screen repair may be covered with a small deductible.

Final Thoughts

Spots on mobile screens are frustrating but manageable. While some issues can be resolved at home, others require professional repair. The key is to identify the type of spot early and take the right action before the problem worsens. By following the prevention tips and handling your device with care, you can keep your phone’s display clean, clear, and long-lasting.
