Screen Test Tool

Test your phone or monitor for dead pixels, light spots, and backlight bleed — auto-cycles through 6 colors.

Use this screen test tool to detect bright spots, dead pixels, and screen burn-in issues.

Run Screen Test

A bright spot on your iPhone screen appears as a localized glowing area that is noticeably brighter than the surrounding pixels. This guide covers bright spots on all iPhone models, from older LCD-based models (iPhone XR, 11, SE) to newer OLED models (iPhone 12, 13, 14, 15, 16), explaining the causes and repair options.

iPhone Screen Bright Spot: Causes, Diagnosis and Repair Options

What Is a Bright Spot on an iPhone Screen

A bright spot on an iPhone screen is a localized area where the display emits more light than the surrounding pixels. Unlike dead pixels (which produce no light and appear dark), bright spots actively glow.

Bright spots can range from tiny pinpoints (single pixel issues) to large cloudy patches. The underlying cause determines whether the spot can be fixed and whether it will spread over time.

The cause of the bright spot differs between iPhone models:

  • LCD iPhones (iPhone XR, 11, SE, 8 and older): Bright spots are usually backlight-related
  • OLED iPhones (iPhone X, XS, 11 Pro, 12, 13, 14, 15, 16): Bright spots are usually pixel-level or pressure-related

Most Common Causes of Bright Spots on iPhone

Physical Pressure Damage

Physical pressure is the leading cause of bright spots on iPhone screens. When force is applied to the display — from dropping the phone, sitting on it, or pressing on the screen — the internal display layers compress and damage in that specific area.

Pressure damage spots appear as:

  • Clearly defined bright patches
  • Most visible against dark backgrounds
  • Permanent and unchanging
  • Often located near the center of the screen
  • May be accompanied by color distortion in the same area

This type of damage cannot be repaired without screen replacement.

Backlight Issues on LCD iPhones

iPhone XR, 11, and SE models use LCD displays with LED backlights. When a backlight component fails or degrades, it can cause light to concentrate in a specific area, creating a bright spot.

Backlight causes include:

  • LED failure: A failing LED in the backlight array creates a brighter-than-normal spot
  • Light guide damage: The light guide plate can be damaged by impact, causing uneven light distribution
  • Adhesive degradation: The adhesive holding backlight layers together can separate, causing localized bright spots

Backlight-related spots glow more intensely at higher brightness levels and are most visible against dark backgrounds.

OLED Pixel Issues on iPhone X and Newer

iPhone 12, 13, 14, 15, and 16 models use OLED displays, which do not have a backlight. Each pixel produces its own light. Bright spots on OLED screens can occur from:

  • Individual pixel malfunction: Certain pixels fail to dim properly, appearing brighter than neighbors
  • Image retention/burn-in: Static images displayed for extended periods cause uneven pixel wear
  • Manufacturing defects: Subpixel driver circuits that are slightly over-driven
  • Drop impact: Physical damage to the pixel circuitry

OLED bright spots tend to be smaller and more pinpoint-like than LCD backlight spots.

Dust Trapped Between Display Layers

Dust particles can become trapped between the display layers during manufacturing or after screen repairs. These appear as:

  • Darker or differently colored spots against bright backgrounds
  • Slightly fuzzy edges
  • May change with viewing angle
  • Often more visible on white screens

Unlike pressure damage spots (which are bright on dark), dust spots are more visible on light backgrounds.

Manufacturing Defects

Some bright spots are factory defects that were not visible when the phone was new but became noticeable over time. Defects can include:

  • Uneven adhesive application between display layers
  • Dust trapped during assembly (missed in quality control)
  • Subpixel driver circuits with minor over-driving

Manufacturing defect spots typically have soft, diffuse edges and may only appear under certain conditions.

How to Diagnose a Bright Spot on Your iPhone

Step 1: Identify the iPhone Model

Your iPhone model determines the likely cause and repair approach:

  • iPhone SE (all generations), iPhone 8 and older: LCD display, backlight is the likely culprit
  • iPhone X, XS, 11 Pro: First OLED iPhones, pixel-level issues more common
  • iPhone 11, XR: LCD displays, backlight issues
  • iPhone 12-16 series: OLED displays, pixel-level or pressure damage

Step 2: Test With Screen Colors

Use the Screen Test Tool to test systematically:

  1. Pure white background: Dust spots become visible; pressure spots may appear darker
  2. Pure black background: Backlight and OLED bright spots glow brightly; pressure spots less visible
  3. Gray background: Often the most revealing — mid-tones show all types clearly
  4. Solid colors: Note whether the bright spot changes color or stays white

Step 3: Brightness Test

Adjust iPhone brightness to maximum and minimum:

  • If the spot glows more intensely at higher brightness: Backlight or OLED issue
  • If the spot stays the same relative brightness: Panel damage

Step 4: Check Warranty Status

  1. Go to support.apple.com/en-us/HT207053
  2. Enter your iPhone serial number (Settings > General > About > Serial Number)
  3. Check warranty status and AppleCare+ eligibility

Step 5: Document for Repair Claims

Take photos of the bright spot against black and white backgrounds. Document:

  • Date first noticed
  • Whether it appeared after an event (drop, pressure)
  • Size and exact location
  • Whether it has changed since first noticed

This documentation is useful for warranty claims and repair quotes.

How to Fix a Bright Spot on an iPhone

Fix 1: Restart and Update iOS

Rule out software causes first:

  1. Restart the iPhone (power off, then on)
  2. Check for iOS updates (Settings > General > Software Update)
  3. Install any available updates
  4. Test again

Some temporary display glitches resolve after a restart or iOS update.

Fix 2: Check AppleCare+ Coverage

If you have AppleCare+:

  1. Go to Settings > General > About > AppleCare+ Coverage Available
  2. Check if accidental damage is covered
  3. Schedule a repair at an Apple Store or Authorized Service Provider
  4. Pay the service fee ($29-$99 depending on model)

Fix 3: Apple Warranty Claim

If under standard warranty:

  1. Visit an Apple Store or Authorized Service Provider
  2. Request a display inspection
  3. If the bright spot is determined to be a manufacturing defect, Apple will repair or replace at no cost

Apple's dead pixel policy typically covers bright spots if they exceed a certain number or size threshold.

Fix 4: Third-Party Repair

For out-of-warranty repairs without AppleCare+:

  • Third-party repair shops: $40-250 depending on model
  • Screens may be genuine Apple parts or high-quality aftermarket
  • Aftermarket screens may have slightly different color accuracy and brightness

Fix 5: Screen Replacement

For permanent bright spots from physical damage:

  • With AppleCare+: $29-$99 service fee
  • Out of warranty (Apple): $129-$329+ depending on model
  • Third-party: $40-250

Replacement screens for iPhone 12-16 use OLED technology and are more expensive than LCD screens for older models.

When Hardware Repair Is Needed

Seek professional repair when the bright spot appeared after physical impact or pressure, the spot is large and in your primary viewing area, the spot is visible on all backgrounds and persists after a restart, the iPhone is under warranty and the spot is a defect, or the iPhone has AppleCare+ and the damage qualifies.

Prevention Tips for iPhone Displays

  • Use a protective case with raised edges and shock absorption
  • Apply a tempered glass screen protector
  • Never put your iPhone in a back pocket — it can be sat on or lost
  • Keep keys and coins in a separate pocket from your iPhone
  • Avoid dropping the iPhone — use both hands and be mindful of surfaces
  • Handle with extra care during physical activities

Conclusion

A bright spot on your iPhone screen is most commonly caused by physical pressure damage from dropping or sitting on the phone, followed by backlight issues on LCD models and OLED pixel issues on newer models. The diagnostic process — testing with screen colors, checking brightness sensitivity, and identifying the iPhone model — narrows down the cause and appropriate repair. Temporary bright spots may resolve after a restart or iOS update. Permanent bright spots require screen replacement. Always check AppleCare+ coverage and warranty status before paying for repairs. Prevention focuses on protective cases, screen protectors, and never putting the iPhone in a position where it can be sat on or crushed.
