Buying Used? iPhone 6s Display Inspection Checklist vs. Common Defects

Are you considering buying a used iPhone 6s? Ensure you know what you're getting into by inspecting the display carefully. A faulty display can significantly degrade the overall user experience, leading to frustration and disappointment. This article will guide you through a thorough display inspection checklist and highlight the most common defects to watch out for.


Importance of Display Quality

The iPhone 6s features a 4.7-inch Retina HD display with 3D Touch, offering a resolution of 1334-by-750 pixels at 326 ppi (pixels per inch). With a display as high-resolution as this, even small defects or issues can be magnified, impacting the user experience.


Why Inspect the Display?

  1. Image Quality: High-quality displays ensure clearer images, smoother videos, and more vibrant colors.
  2. User Experience: A good display enhances the experience for activities like browsing, gaming, and watching videos.
  3. Value for Money: A functioning display increases the resale value of the device, making it a worthwhile investment.

Checklist for iPhone 6s Display Inspection

Before making a purchase, follow these steps to ensure the display is in good condition:


Step-by-Step Process:

  1. Physical Inspection
  2. Step: Look for scratches, cracks, or visible damage.
  3. Rationale: Surface damage can be easily visible and affects the appearance and functionality.

  4. Clean the Display

  5. Step: Use a soft lint-free cloth or a specialized iPhone cleaning solution to remove dust and fingerprints.
  6. Rationale: A clean display allows for a more accurate inspection.

  7. Test Brightness and Contrast

  8. Step: Adjust the brightness settings and check for uniformity across the screen. Ensure the contrast is consistent.
  9. Rationale: Uneven brightness or contrast issues may indicate a potential problem with the backlight or color uniformity.

  10. Look for Glitches and Dead Pixels

  11. Step: Use a display tester tool or app (e.g., "Dead Pixel Fix" on iOS) to identify any dead or stuck pixels.
  12. Rationale: Glitches or dead pixels can diminish the overall display quality, making it less enjoyable to use.

  13. Test Touch Functionality

  14. Step: Tap, swipe, and pinch the screen to ensure touch responsiveness is consistent.
  15. Rationale: Poor touch functionality can render the device unusable and affect the user experience.

  16. Explore XR Content


  17. Step: Show photos, videos, and run intensive apps to see how the display performs under different conditions.
  18. Rationale: Real-world usage can help highlight any inconsistencies or defects not obvious in a static test.

Here are the most common display defects you should be aware of when inspecting a used iPhone 6s:

How to Identify and Test Common Defects

Here's how to identify and test for common display defects:


Dead Pixels

  1. Display Testers: Use tools like "Dead Pixel Fix" on iOS to look for unresponsive pixels.
  2. Contrast Pattern: Use a solid color background or an image with high contrast to better identify dead pixels.

Scratches

  1. Inspect Actively: Use a magnifying glass to examine for visible scratches.
  2. Feel the Display: Gently feel the surface for differences in texture.

Backlight Bleed

  1. Dark Screens: Set the display to a dark mode and look for any light leakage around the edges.
  2. Contrast Image: Use a black background to highlight any backlight bleed.

Color Shifting

  1. Visible Uniformity Check: Look for any noticeable color changes across the image or screen.
  2. Calibration Tools: Use display calibration tools to test for color consistency.

Screen Burn-in

  1. Static Image: Display a static image to check if any ghosting remains.
  2. Advanced Testing: Use tools like "Pixel Fix" to monitor if the issue persists.
